Karl-Dieter Grüske
Nürnberg (FAU) looks back on a 271-year long history of
teaching, scholarship, and research. At present, we are
one of the largest research universities in Germany with nearly 39,700 students, 660
professorships and 13,000 members of staff in research and administration, including
our university hospitals. According to several parameters, our University ranks among
the top universities in Germany. The Erlangen-Nuremberg region has developed into
a world-class centre for microwaves and photonics in recent times – not least because
of several institutes both at and affiliated with FAU, the two Fraunhofer Institutes and
a Max Planck Institute for the Science of Light. FAU provides perfect conditions for
interdisciplinary academic work to students and researchers alike. Within the wider
Nuremberg metropolitan area, FAU likewise plays a crucial role as an employer, incubator for innovation and education hub.
Apart from outstanding research and excellent educational facilities, the Nuremberg
metropolitan area and Franconia offer many tourist attractions that are worth visiting.
Therefore, I strongly recommend that you use your free time here to have a look around
and get to know the region.
I wish you all some pleasant days here with us; do have an enriching conference and
inspiring discussions. Be our distinguished guests and enjoy your stay!

Monday – Opening Ceremony (11:30 – 13:00, Room G1)
Embrace Circuit Nonlinearity to get Transmitter Linearity and Energy
Efficiency
Dr. Earl Mc Cune, IEEE MTT Distinguished Microwave Lecturer, Besser Associates,
USA
Wireless communications signals have evolved greatly over the past century, from the
use of Morse Code to very complicated digital modulation schemes such as wideband
CDMA (WCDMA) and 3GPP Long-term evolution (LTE). This progression challenges
the design of transmitters to be simultaneously energy efficient, low distortion, and
spectrally clean. The increasing peak-to-average power ratio (PAPR) characteristic of
these signals is a particular problem. Because it is important to understand why this
is happening this presentation begins with a discussion of the physical implications of
Shannon’s Capacity Limit combined with the Fourier Transform.
A ’backwards’ design perspective is then presented, where we begin design from a
maximally energy efficient circuit (a switch) and then make it generate the required
signals instead of the conventional approach of beginning with linear circuitry and then
finding ways to improve its energy efficiency. This directly leads to the design and
implementation of polar-modulation to improve both the energy efficiency of the power
amplifier and linearity of the transmitter. Design of intentionally compressed circuitry
is very different from conventional linear amplifier techniques, and these new design
techniques will be discussed.
The presentation will cover the use of both linear amplifiers and switches for the power
amplifier module, and the implications of using these approaches on the power supply
design, system integration, and performance measures. This presentation will bring the
subjects of OFDM, Shannon’s theorem, spectral efficiency, and switch-mode amplifiers
together in an exposition of polar modulation transmitters that is both entertaining and
informative.

Advanced Multistatic Radar for Personnel Screening with MillimeterWaves
Dr. Sherif Sayed Ahmed, Rohde & Schwarz, Munich, Germany
Securing air traffic has become very challenging nowadays due to the unpredictable
threats and the ever-increasing demand on aviation transportation. Securing passengers as well as critical infrastructure buildings, e.g. airports, is progressively relying
on advanced technologies to efficiently and reliably detect threats as early as possible. The introduction of body scanners some years ago to the airport security chain
was one of the important measures to achieve threat detection including metallic and
nonmetallic items, e.g., plastic explosives and ceramic knives. By which, a major security gap of the conventional metal detector gates is basically eliminated. To enhance
their capabilities, however, demands arose to utilize millimeter-wave technology along
with full-electronic screening. Bearing in mind the associated costs of millimeter-wave
components and their integration, the movement towards multistatic operation in order
to reduce the number of needed channels has become essential. Advanced digital
processing techniques allow in addition to boost the capabilities of these imaging radar
systems to a new era, where close-range operation with large apertures and high 3D
resolution becomes a reality. This talk presents the state of the art in the screening
20
GeMiC 2015 – Conference Programme
research and technical expertise, an advanced technological solution has been introduced recently and is expected to serve the security branch at various locations inside
and outside the airport’s space.
Dr.-Ing. Sherif S. Ahmed is with Rohde & Schwarz in Munich, Germany,
where he is currently specialized in modern microwave imaging technologies. For several years, Dr. Ahmed has been working on advancing personnel screening methods for the airport security sector. His current R&D activities include: near-field microwave imaging, stand-off imaging, along with
the non-destructive testing, multistatic radar, advanced signal-processing
techniques and last but not least terahertz technology.
Dr. Ahmed received the B.Sc. degree with Honors in electronics and communication engineering
from Cairo University, Cairo, Egypt, in 2004, the M.Sc. degree in microwave engineering from the
Technische Universität München, Munich, Germany, in 2007, and the doctoral degree (Dr.-Ing)
with Honors from the University of Erlangen-Nuremberg, Erlangen, Germany, in 2013. He was
the recipient of the University Academic Award of the Technische Universität München in 2007,
the Innovation Award of Rohde & Schwarz in 2009, and the IEEE MTT Microwave Prize Award
in 2013.

An Engineering Approach Towards Creating Ubiquitous THz Applications
Dr. Stepan Lucyszyn, European Microwave Lecturer and Director, Centre for Terahertz
Science and Engineering, Imperial College London
Within the wider terahertz (THz) frequency range (ca. 0.1 to 10 THz), the sub-millimetre
wave frequency band (between 0.3 and 3 THz) is still considered to be a largely unexplored part of the electromagnetic spectrum. This ‘THz Gap’, between conventional
electronics and photonics, offers the real potential for both scientific and commercial
exploitation. However, while the majority of THz groups focus on the former, it is the
latter that offers the key to bridge the THz Gap to ubiquitous applications. To this
end, new engineering solutions are needed in modelling (mathematical & numerical),
design (synthesis & analysis) and fabrications (precision & volume production).
As ubiquitous THz applications emerge, the costs of associated passive components,
active devices and metrology will fall, creating a positive spiral of growth in all areas;
enhancing our modern day living and with the prospect of a huge societal and economic impact. This lecture will examine the various facets associated with adopting an
engineering approach towards creating ubiquitous THz applications. More specifically,
for the many engineers currently working at microwave and millimetre-wave frequencies (below ca. 100 GHz), the challenges for working with shorter wavelengths and
with more complicated carrier transport and molecular physics will be explained. The
lecture will also give, by example, a unique perspective on THz engineering – with conventional approaches and new paradigm shifts – from nano structures, metamaterials
and solid-state & vacuum electronics to complete systems level integration, ubiquitous
applications and their impact.

S01.1: Design Method for Harmonically-Tuned, Dynamic Load-Modulated Power
Amplifiers
Konstantinos Mimis1 , Gavin Watkins1

Toshiba Research Europe Ltd., United Kingdom
Time: 14:00–14:00
In this paper, an alternative technique for the design of harmonically-tuned, dynamic
load-modulated power amplifiers is proposed, investigated and compared against traditional load-pull in simulations. The method exploits the flexibility of "continuous"
modes of amplifier operation while it optimises the harmonic terminations for back-off
performance. The large signal transistor model of a 10 W GaN device (CGH40010) is
used to simulate performances at two frequencies of 0.9 GHz and 2 GHz. The simulated efficiencies and intrinsic waveforms show that the proposed method represents
a more comprehensive design path for harmonically tuned dynamic load-modulated
PAs. Moreover, it can lead to optimised performance for the amplification of modulated
signals.

Time: 14:20–14:20
Linearity, along with efficiency and bandwidth, belongs to the fundamental requirements of power amplifiers for nowadays communications systems. This paper discusses how to bring together these partly contradictory goals in power amplifier design.
Continuous class-J PAs provide a constant efficiency over a large bandwidth. However,
the linearity is not constant due to the unequal current and voltage waveforms along
the design space of the continuum. Nevertheless, it is possible to equalize linearity of
28
GeMiC 2015 – Conference Programme
such a PA over the desired bandwidth. For the PA presented, −50 dBc ACLR with an
average power of 38 dBm and an average efficiency of 21.5 % were achieved at 2.14
GHz using a WCDMA test signal . For CW measurements, 48.5 dBm maximum power
and 63 % peak drain-efficiency were reached.
S01.3: New Output Network Design Approach for Voltage-Mode Class-S PAs

Ferdinand-Braun Institut (FBH), Leibniz-Institut für Höchstfrequenztechnik, Germany
Time: 14:40–14:40
This paper presents a new approach for realizing the output network of class-S power
amplifiers in the 900 MHz band. The idea is to use bond-wires instead of lumped
inductors thus improving Q factor and broadband impedance termination at the output
of the switching stage. A filter made of bond-wires and planar capacitor was designed
and fabricated. Measurements were also performed in a class-S PA module and
compared to the convention. Measurements of the proposed network were performed
and compared with filter solution using SMD elements.
S01.4: Complexity of DPD Linearization in the full RF-Band for a WiMAX Power
Amplifier

Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Germany
Time: 15:00–15:00
In this paper, the influence of bandwidth on DPD is investigated empirically. A classAB GaN-HEMT power amplifier (PA) targeting the 3.5 GHz band for WiMAX is used
with a 20 MHz OFDM signal. It is found that frequency dependent memory effects in
the band have a strong impact on the amount of memory taps needed for the DPD
predistorter model. The overall characteristic is dominated by the non-linear behavior
of the transistor, the memory effects, and the IQ imbalance introduced by the low cost
modulation hardware. Using DPD models with memory that can handle IQ imbalance
the EVM is improved by at least 12 dB in backed-off operation.

In this paper, a high power, high efficiency and wideband two-stage GaN-HEMT power
amplifier (PA) is presented and illustrated together with the design, implementation, and
measured results. The scope of the design was to build broadband input-, interstage-,
and output matching networks based on source-/load-pull simulations and a systematic approach. The large-signal measurements indicate that the achieved output power
is higher than 50 W, the power gain locates in the range of 27-28 dB, and the PowerAdded-Efficiency (PAE) reaches 45-55 % over a frequency range of 2-2.8 GHz. Moreover, linearized modulated measurements were also performed by applying a 5 MHz
Wideband Code Division Multiple Access (WCDMA) signal with 9 dB peak-to-average
power ratio (PAPR). The resulted adjacent channel leakage ratio (ACLR) at 2.2 GHz
was achieved at -38 dBc, with an average output power of 5 W and an average PAE
of 18 %.

In this paper, we present a novel time domain technique for measuring the relative
permittivity er of samples based on pseudonoise test signals (M-sequences). Analog
correlation is the key enabler of our system, providing high time resolution while minimising the effort required for sampling. Moreover, a linear error model is proposed
and the system’s measurement uncertainty is assessed. A comparison with reference
measurements of PTFE samples concludes this paper.

Time: 14:20–14:20
The space observation radar TIRA (Tracking and Imaging Radar) is a system unique
in Europe: The system primarily serves as the central experimental facility for develof objects in space. TIRA also provides valuable support for space missions: space
agencies from all over the world use the special capabilities of the Fraunhofer scientists and their system. Due to the recent renewal of the radome, it was required that
the quality and electromagnetic properties of the radome panel material was verified
before mounting. There are several ways to determine the dielectric and magnetic
properties of bulk material, e.g. capacitor or co-axial probe measurements but only
few techniques can be used for non-destructive measurements of thin dielectric sheets
at higher RF and millimeter wave frequencies with high accuracy. The proposed article
describes a measurement method based on an open rectangular cavity attached to a
specially fabricated fixture. The theoretical background, the mechanical design will be
described and several measurement results will be shown.

During recent years the developments in microwave material processing have shown
that the microwave curing of fiber reinforced plastics can be much more energy efficient compared to conventional heating methods. This motivated the development of
various microwave systems and processes. Nevertheless, for a successful system and
process design the detailed knowledge of the dielectric materials parameters is mandatory. Therefore, a system for in-situ monitoring of curing processes of thermoset resins
under microwave heating was developed. The main function of the measurements

opment and investigation of radar techniques for the detection and reconnaissance
instrument is the dielectric characterization of resins based on the cavity perturbation
technique. The electromagnetic source used for dielectric characterization of the material under test is used for dielectric heating at the same time. The single mode cavity
operates at 2.45 GHz in the TE111 mode. It has an unloaded quality factor of 11500.
Moreover, a calorimetric analysis of the exothermal curing process is envisaged.

cal and Electronic Engineering, Australia
Time: 15:00–15:00
This paper proposes the principle for rotation sensing based on an open-ended microstrip line loaded with a split ring resonator (SRR). It is shown that the variations in
the depth of the resonant notch in the reflection coefficient of the structure can be used
to sense the rotation angle of the SRR. This effect arises from the rotation-induced
break of symmetry for this geometry. The proposed sensor benefits from a compact
size, relatively high dynamic range, and immunity to the environmental changes such
as temperature variations.
S02.5: A Cylindrical Cavity Resonator for Material Measurements with Coupled
Resonant Modes for Sensing and Position Offset Compensation of the Dielectric Specimen

Time: 15:20–15:20
A cylindrical cavity resonator is separated into two resonating sections by loading it with
a metal sheet in the middle of the cavity. The metal sheet of finite thickness contains a
circular aperture to support symmetric and asymmetric modes in the cavity. The pair
of two modes can be simultaneously employed for sensing dielectric characteristics
of rod-shaped specimen passing from top to bottom through the cylindrical cavity. In
32
GeMiC 2015 – Conference Programme
conventional cavities employed for sensing dielectric rods or tubes, a single resonance
TM010 mode may result in unwanted detuning of the frequency. The unwanted shift
in resonance frequency is caused due to nonuniform electric field distribution, where
the total volume of the sensing region is a large fraction of the overall cavity volume.
Unlike the conventional design, the main advantage of coupled cavity arrangement is
to distinguish the position offset of the dielectric specimen within the sensing region
of the nonuniform electric field. The asymmetric mode functions similar to the convendielectric specimen towards the edges.

This contribution deals with the analysis of a modified Saleh-Valenzuela channel model
for the UHF band. The development of the channel model is based on indoor channel
measurements within a large exhibition hall in a line-of-sight scenario in order to
study new cognitive radio systems. Contrary to the conventional modeling, the path
voltage gain is modeled by a Rayleigh probability density function. Due to the broadband consideration the channel model can be used for a variety of different operating
frequencies.
S03.3: A Digital Up-Sampling Technique for a Heterodyne Digital Centric Transmitter
Pierre Bousseaud1 , Renato Negra1

RWTH Aachen University, Germany
Time: 16:40–16:40
In this paper, a digital up-sampling technique is presented for digital communication
transmitters. This method allows to up-sample the I/Q baseband modulated signals to
an intermediate frequency based on a 4:1 multiplexing technique, before being again
up-converted at the carrier frequency. The frequency conversion is made in two steps
and permits to avoid the nonlinear behavior of direct up-converting architectures. Also,
the mutual coupling between the output power amplifier (PA) and the phase-locked
loop (PLL) can be reduced by choosing the local oscillator frequency (LO) far enough
from the carrier output frequency. A fully integrated CMOS transmitter with an on chip
PA is thus becoming feasible. A PLL at the frequency of 4.8 GHz has been designed
in a 65nm CMOS process along with a digital 4:1 multiplexer in order to target the
band-VII Long Term Evolution (LTE) applications in the 2.55 GHz frequency.

The signal-to-noise ratio (SNR) of the analog-to-digital converter (ADC) typically limits
the sensitivity of wideband receivers for Software Defined Radio (SDR) or Cognitive
34

Radio (CR) applications in the presence of a strong interfering signal. A Stacked ADC
configuration – two or more parallel ADCs, each with a different drive level – promises
an increased dynamic range of the analog-to-digital interface. Based on simulation
and measurement results, the paper will discuss the capability of the Stacked ADC
configuration with respect to interfering signal characteristic.
S03.5: A Wide Dynamic Range Four-Port Spectrum Sensor for Cognitive Radio
Ilmenau University of Technology, Germany; 2 Technische Universität Ilmenau, Ger-
many
Time: 17:20–17:20
This paper presents a compact, low-cost spectrum sensor with very large dynamic
range to detect arbitrarily modulated input signals with respect to identifying the spectrum holes available for cognitive radio applications. The sensing technique is based
on the combination of a tunable preselector filter and a four-port circuit consisting of
logarithmic diode detectors. Since the four-port is a passive circuit, the sensed signal is processed without requiring additional power consuming nonlinear circuits (like
mixers and its necessary local oscillator driver circuits) in the schematic arrangement.
Also, the use of logarithmic diode detectors enables the detection of signals over a
wide dynamic range exceeding 80 dB, making it almost comparable to that of available heterodyne receivers. Such a technique provides a fast, low-cost and low-power
sensing strategy, therefore making it an extremely interesting alternative to the present
heterodyne receivers used for rapid wide-band sensing, which is a key prerequisite for
any cognitive radio system.

Time: 16:20–16:20
Printed ultra-wideband (UWB) monopole antennas are proposed with compact size
and single/dual band-notched characteristics to prevent interference with nearby communication systems. It is shown that a dumbbell-shaped defect in the radiating element
of a UWB monopole antenna can produce a notch band. The frequency of the notch
can be easily adjusted by changing the physical dimensions of the defected structure.
It is further shown that, a pair of complementary split ring resonators (CSRRs) embedded in the dumbbell-shaped defect can be used to produce a second notch. The
proposed dual band-notched antenna can be used for the rejection of interference
with Worldwide Interoperability for Microwave Access (WiMAX) systems covering the
3.3–3.6 GHz band, and either lower or upper wireless local area networks (WLANs)
operating in the 5.15–5.35 GHz and 5.725–5.825 GHz bands, respectively.

A novel concept for implementing delay elements in chipless TDR RFID tags is presented. The concept is based on filter design techniques and aims for low dispersive
36

and compact designs. Since dispersion has influence on ISI and phase distortion, a
reduction of the dispersion leads to an increase in the system’s performance and the
reading range, respectively. This is first analyzed with the help of a system-theoretical
simulation. From the filter design methods considered in this paper, the Butterworth
method shows to be suited best for this purpose. An adaption of the Butterworth filter
design regarding group delay design requirements is derived. A filter design is carried out and a delay section with low group delay dispersion is implemented. Finally,

Based on the properties of surface modes in slab waveguides, it is shown that the
cutoff of the surface modes can be obtained from the zeros of the reflection coefficient
at wavenumbers close to the light line. Afterwards, a surface wave periodic structure
is analyzed by the method of excitation of eigenmodes. By considering the field distribution in surface modes of the open waveguide structure, the unit cells are loaded by
appropriate metamaterial resonators. The metamaterial resonators introduce a new
surface mode below their resonant frequency while the eigenmodes of the guided
structure are not affected strongly. This method can be employed to obtain an arbitrary
frequency band for near field imaging applications.

In this paper, a novel electromagnetic bandgap (EBG) structure has been introduced.
Initially, the EBG structure is theoretically analysed using lumped element equivalent
circuit model. Thereafter, the dispersion diagram of the EBG is extracted by simulating the EBG unit cell in eigenmode Solver of CST Microwave Studio. The simulated
bandgap values shown by the dispersion diagram are then experimentally validated by
using a test structure which consists of a 4x5 matrix of the novel EBG unit cells. The
simulated and measured insertion loss of this test structure depict surface wave suppression within the estimated frequency bandgaps. Finally, three rows each consisting
of 7 novel EBG unit cells are integrated between two patch antennas. The mutual
coupling reduction between the patch antennas with and without the novel EBG is
compared to show its surface wave suppression effect.

SP1.1: Jamming and Spoofing of GNSS Signals – An Underestimated Risk?!
Alexander Rügamer1

Time: 09:00–09:00
GNSS technology is used for many applications: The surveying industry uses GNSS
for monitoring the continental drift, stakeout fixed-points, measuring maps of areas and
many other location based services. The construction industry uses GNSS for machine
control and logistics, the agriculture for precise farming, power steering assists and
other tasks like manure, reaping and plowing. Since the last 10 years GNSS also
entered in many daily life applications like car navigation and location based services
(Google Maps, Facebook). But GNSS is also used as a sensor for many safety-critical
applications: the example of guided lading approach of airplanes is well known but it
is less known that GNSS – and here specific the Open Service of the US NAVSTAR
GPS – is used as a crucial sensor for timing and synchronization of reference stations
for telecommunication, electrical power supplies, exchange markets and banks.
For many years the availability and faultless function of GNSS was taken for granted.
Jamming (the intentional interference targeting the unavailability of the system) as well
38
GeMiC 2015 – Conference Programme
as spoofing (the faking of a false position/time towards a target GNSS receiver) was
no concern for nearly all users except the military.
But recent events started a gradual paradigm shift: the unintentional jamming of the
Newark Airport, NY, USA by an UPS driver with a US$ 100 devices available on
ebay; the capturing of a US drone using a GPS spoofer by Iran; the demonstration of
students from the University of Austin, Texas, US to hijack a US$ 80 million dollar Yacht
to tamper the phase measurement units used for energy network synchronization and
control.
In this presentation we review these events and show how our currently used GNSS
technology was attacked and affected. Then we discuss different measures to detect
and even mitigate these threats on algorithmic, receiver, antenna and system level.
Finally, we conclude with providing solutions and recommendations for hardening
and protecting GNSS receivers by e.g. using array antennas and/or services like the
Galileo Public Regulated Service (PRS) with civilian anti-spoofing guaranteed by the
strong encryption used there.

important. For positioning, satellite receivers, GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System), WLAN (Wireless

approaches for seamless pedestrian navigation in indoor and outdoor environments.
Commonly the first choice for navigation is the Global Positioning System (GPS). However, the lack of precision and availability of GPS in urban and indoor environments is

with a self-made spoofer as well as their laboratory demonstration to use this spoofer
a prevalent problem. As an alternative or complementary solution for indoor environments positioning approaches based on the received signal strength (RSS) in WLANs.
Nowadays, because of an increasing number of public and private base stations WLAN
positioning becomes more and more attractive for navigation and is already integrated
into many smart phones. The positioning accuracy can be improved by combining
WLAN positioning with dead reckoning, using low cost inertial sensors.
One remaining challenge is estimating the heading, or better the pose, of a person.
Indoors, magnetic disturbances lead to unreliable compass outputs. Estimating the
heading of a pedestrian using the speed vector calculated from consecutive positions
has a very low accuracy, as pedestrians move very slowly compared to the positioning
variance of indoor positioning systems. Also, pedestrians can turn anytime without
changing their position.
A tracking approach for estimating the azimuth angle regarding north and a twodimensional position of a mobile unit carried by a pedestrian is presented. Using
WLAN signal strength measurements the position of a mobile receiver can be estimated using so called fingerprinting methods. If the signal strengths measurements
are collected with directional antennas additionally the azimuth can be estimated. For
sensor data fusion of WLAN signal strength measurements, acceleration measurements and angular rate measurements a particle filter is presented. Measurement
results are presented. Including step detection based on acceleration measurements
reduces mainly the positioning error, including angular rate measurements reduces
mainly the azimuth estimation error. Especially in indoor environments this approach
facilitates the use of electronic guides that offer additional information by means of
augmented reality, e.g. on museum exhibits in visual range.

SP1.4: Sensor networks in animal tracking: future perspectives on wildlife research

Museum für Naturkunde Berlin, Germany
Recent technical advances such as satellite based animal localization and automatized data collection have revolutionized wildlife research. However, most applications
are restricted to the use on medium-sized to large mammals and birds due to the considerable size of available transmitters. Hence utilization of such modern technology
is difficult for small-bodied bats, which comprise the second largest order of mammals
with more than 1100 species worldwide. For this reason radio-telemetry still represents
the state of the art of bat tracking, a method that requires high labor costs for the manual observation of one or few individuals at a time. A system for tracking bats using
sensor technology, combining stationary and mobile nodes that exchange information,
will revolutionize research on behavioral ecology of bats. We present applications of
the BATS sensor network that will give deep insight into the secret life of bats.

The sensor technology (described in the other contributions of this session) being
developed to track bats in their wildlife will allow to generate a stream of positions
for a couple of bats simultaneously. Biologists are interested in extracting behavioral
patterns from these streams. They have some knowledge of bat behavior, so in the
first step, known patterns are defined. If they can be detected in the position streams,

the effectiveness of the approach is shown, and interest can be moved to the remaining parts of the streams. For this purpose, low-level events are defined that can be
extracted from the streams exploiting continuous queries. They may have a duration.
Examples are "rose up", "went down", "paused" and some more. High-level events can
then be generated from these by defining patterns, e.g. sequences. Complex-event
processing is used to define the patterns and to generate the events from them, like
"ate beetle" and "flew straight". The top-most category are activities. Each bat performs exactly one activity at a time, so its behavior is given by a sequence of activities.
Examples are "sleeping", "hunting", and "flying to a destination". Activities can also be
regarded as the state of the animal. A change of activity (or change of state) is indicated by a specific event. Hence, bat behavior can be modeled as a state-transition
diagram, where transitions are labeled with events. The article presents the definitions of events and activities and shows their detection capabilities on some example
position streams.

Time: 12:00–12:00
Energy-critical systems such as tiny and ultra-light mobile sensor nodes that are used
to track the behavior of their animal hosts (e.g., bats) demand for a new flexible system software infrastructure. A major challenge is the restricted availability of system
resources (e.g., energy, memory), but also the occurrence of spontaneous network
connections with other mobile and stationary sensor nodes in range. Hence, similar
to underlying hardware components, the operating system has to be light-weight (in
terms of memory usage), energy-aware (in terms of energy-efficient algorithms and
system components), and needs to provide the infrastructure that serves as a basis for
other involved computer-science and electrical-engineering teams (e.g., which provide
efficient network protocols).
In this talk, we present our latest results of our research on an energy-aware operating
system supporting the BATS research project. We propose methodologies to quantify
the energy consumption of operating-system components underneath but also applications running on top. We shine a light on the operating system’s dynamic software
reconfiguration and updating capabilities, which give us more flexibility in testing different implementations. Moreover, this allows us to save further energy by deploying
code that makes sure that a mobile sensor node is always in the most energy-efficient
state its current geographical position, workload, and intended use permit.

Time: 13:00–13:00
The present publication describes an innovative concept for fawn saving during pasture
mowing in spring time. Conventional approaches like scaring by dogs or scarecrows
are ineffective and time consuming for large areas. Other technical solutions have
different drawbacks or insufficient search performance. Within the active UHF RFID
localization system the process of identifying fawns and rescuing during mowing is
separated. To recover them during the mowing sequence the fawns, covered in high
and thick grass, are marked with active UHF RFID Transponders. The UHF RFID
Transponder is mounted at the eavesdropper of the fawn. Through the usage of chip
antennae a size of a 2 euro coin is reached despite working within the UHF band. Due
to an unknown position of the transponder different approaches to ensure detection
are investigated. An efficient power management enables a lifetime of 1 month. In
addition the UHF RFID Transponder is supplied environmentally friendly with a zinc
air battery.

This paper describes how dynamic range and accuracy of an on-wafer load pull measurement system can be improved without costly investment in equipment. Applying
prematching to the transistors on the wafer reduces ohmic losses, leads to a better
figure of merit $\Delta$GT, and thus increases the accuracy of the whole system. The
approach is verified for X-band GaN power transistors.

around it. Thus, the resonant frequency is scaled accordingly based on the permittivities of various materials under test. Therefore, the permittivity information is translated
to a resonant frequency shift of the patch antenna. The patch antenna was fabricated
on Isola Astra 300 microwave substrate and measured with different solid and liquid
material on top of the patch antenna. In addition to that a simple readout circuit was
proposed and realized in 250 nm SiGe BiCMOS, which can be used in the future to
convert the reflected power of the antenna into a corresponding DC-value.

This paper is about first fundamental investigations whether radar technology can detect smallest impurities in the production of high-quality granulated sugar. Based on
some theoretical considerations the sensitivity of microwave interaction with some
reference targets and some typical impurity particles is explored using a measurement
setup at predominantly W band (75 – 110 GHz). In dependence of various adjustable
parameters like bi-static angle, polarization, and frequency band a selection of suitable measurement configurations is finally discussed. The goal is to detect smallest
impurities primarily inside and of course as well on the surface of a sugar heap.

Current-handling capability of interconnection lines must be considered to avoid electromigration. In monolithic design, all design rules have to be rigorously followed which
indicates that the maximum metal width is limited. In order to handle high current
and simultaneously obey the design rules, stacked and mesh interconnections are
employed. In this paper five coplanar waveguides (CPWs) for high current-handling
are investigated using a commercial CMOS technology. The measurement shows that
a mesh CPW reaches lower attenuation constant than stacking of metals under similar
current carrying capability. The lowest measured attenuation is 0.81 dB/mm at 10 GHz
and 1.46 dB/mm at 40 GHz in a mesh CPW, which can continuously flow a DC current
of 145 mA without electromigration.

The technological advancement of upcoming synthetic aperture radar (SAR) satellite
missions leads to innovative challenges for the calibration as well. In order to provide
an active reference target for an accurate absolute radiometric calibration the knowledge of the backscattering characteristics is essential. For the recently developed DLR
C-band transponder named "Kalibri" several strategies for an accurate determination of
the radar cross section (RCS) have been analyzed. Based on comparison with respect
to accuracy and feasibility, several recommendations for the best transponder calibration strategy could be established. The resulting RCS of the transponders retrieved
from the most suitable measurement method is presented as well as a cross-validation
to prove the plausibility of these results.

grated Waveguide (SIW). The proposed divider consists of cascaded-connected N-1
directional couplers inserted a number of metallic posts within the SIW with suitable
coupling coefficients and a right angle corner, and realizes an equal power division
in a same direction by using honeycomb structures composed of a large number of
small-size holes vertically installed with the SIW. By optimizing the circuit parameters
of directional couplers and the right-angle corner at a center frequency of 17 GHz
based on the H-plane planar circuit approach [1], a good performance of an equal
power division within ±0.3 dB unbalance and 20 dB return loss can be obtained with
a relative bandwidth of about 2%. Verification of this design procedure is performed
by em-simulations and experiments.

This work presents a loss compensated cascaded single-stage distributed amplifier
(CSSDA) in commercial 65 nm CMOS technology. The CSSDA is composed of three
distributed stages connected in a cascade configuration to target high gain. The idle
interstage drain terminations are omitted because of multiplicative gain mechanism.
The high gain is maintained over very large bandwidth through the inductive peaking
technique. Further, CSSDA single cell is modified by a loss compensation technique
to remove the high frequency losses of the artificial transmission lines which shows
a significant enhancement in gain bandwidth (GBW) product. The simulation results
show a GBW of 540 GHz for the loss compensated CSSDA (LC-CSSDA) which is
significantly higher than GBW of 350 GHz for conventional CSSDA. The 2-stage (LCCSSDA) shows a GBW of 835 GHz which is almost twice the GBW (426 GHz) of a
conventional 2-stage CSSDA.

This paper presents a quadrature-phase coupler providing 90-degree output phasedifference over wider bandwidth compared to other single-stage planar couplers. The
proposed design is suited for the applications where high power RF signals need to be
combined with quadrature phase. It uses a symmetric rat-race coupler to achieve wider
bandwidth as compared to its asymmetric counterparts. The proposed coupler has a
peak-to-peak phase-deviation of 16 degrees and a magnitude-imbalance of lower than
0.5 dB over the entire bandwidth spanning 2 GHz to 3 GHz. The measurement results
comparing the proposed coupler with a) a branch-line coupler, b) a rat-race coupler

This contribution extends previous work of the authors on microwave couplers using
vias. In [1] a novel concept for microwave coupler design using vias (plated through
holes) in multilayered printed circuit boards was presented. By placing thru vias inside
a ground via cage, high coupling between the vias can be observed. In this work it
is shown that appropriate definition of via ports leads to a filter-like behavior of the
structure. By adjusting the dimensions of the structure and by adding further thru
vias the filter behavior can be controlled. Results are validated by physics-based and
full-wave simulations up to 25 GHz.

Time: 09:30–09:30
Where unused frequency bands become scarce, their resourceful handling is essential.
Consequential, to enable best use of various frequency bands with a single device, the
need for reconfigurability emerges. Complementary to already existing technologies,
a novel transistor-based circuit is introduced that makes passive, reciprocal, electronic
reactive tuning possible. Ultimately, a tuneable inductance was chosen as an example
for reactance circuits due to its outstanding relevance for modern, reconfigurable circuit
design.
The general development process of the inductance circuit is outlined through an
abstracted process overview. It enables a broad understanding of the challenges
and possibilities of this approach. Also, by extensive circuit analysis with ideal and
non-ideal element values, the gap between numerical simulation and guidelines for
practical implementation can be narrowed. From the resulting analytic expression, the

key figures of an electronic tuneable inductance are derived, namely the range of
inductive tuning, the quality factor and the achievable frequency range.
These values enable the circuit designer to set up a reasonable starting point for developing a tuneable inductance circuit and gives the means to estimate its unprecedented,
passive output behaviour.

The problem of transmission of electromagnetic wave through a thin conductive ferromagnetic layer is considered here with the assumption that its thickness is less than
skin depth. It is supposed that the conductive film is sputtered on a dielectric substrate.
Solution of boundary problem jointly with the spectrum of eigenmodes under magnetic resonance condition and spin pinning conditions gives an opportunity to develop
the algorithm of numerical calculation of the transmission and reflection coefficients.
Transmission of microwaves through thin ferromagnetic films has been experimentally
studied. The experimental investigations of millimeter waveband penetration through

description of one dimensional (1-D) wave propagation in layered media with moving boundaries and an approximate method to calculate backscattered signals from
moving objects of arbitrary shape with the help of full wave simulations of motionless, stationary objects. Both approaches are matching well for the shown kind of
applications. In this publication the author presents the deviations between both approaches and their origin. Furthermore a new FDTD approach is presented for the
one-dimensional case to consider the Doppler effect of moving boundaries in layered
media. An outlook for the three-dimensional approach is given.

Time: 08:30–08:30
In this paper we propose an approach to improve the B1 distribution in terms of homogeneity and penetration depth of a coil element by utilizing a high impedance surface
(HIS) as the RF shield for 7 T magnetic resonance imaging (MRI). The transverse
magnetic field distribution in the case of a HIS and a perfect electrical conductor (PEC)
being the shielding plate are compared for different separation distances from the
dipole coil to the shielding plate. As the PEC shield is adjacent to the dipole coil, an
undesired surface current is induced on the PEC shielding plate by the dipole coil,
whereas the induced surface current on the HIS shield is sufficiently suppressed due
to the high surface impedance. As a result, the dipole coil with a HIS shield exhibits
a broader and stronger field distribution, and thus achieves an improvement on the
transverse B1 homogeneity as well as the penetration depth. As the separation distance increases, the impact of the induced current is weakened and thus variations on
the field distribution with different shielding scenarios (HIS and PEC) are reduced. The
proposed approach has been validated by numerical simulations and experimental
measurements, which show a good agreement.

MRI RF excitation with various local transmit antennas has been compared to the
commonly used full-body transmit antenna in terms of transmit field distribution, field
strength and local SAR. The antennas (volume and surface coils) have been designed,
decoupled and matched by using a 3D field simulation software. The examined objects, a liquid-filled cylindric phantom and the arm of a human body model have been
included in the simulation setup. According to this study, the use of local transmit coils
results in an immense reduction of required transmit power and a saving potential
of local SAR, independent of the choice of local antenna type. However, concerning
homogeneity birdcage coils offer the best performance.

In MRI systems, RF fields are affected by the presence of the human body in the
scanner causing mismatch between the RF coil and the feed cable. A power amplifier
incorporating an unconventional Cartesian feedback loop is presented which works to
maintain a fixed current in the RF coil against impedance variations. The performance
of the system is investigated by model simulation, including stability analysis, linearity
improvement and mismatch compensation. A prototype amplifier is measured to verify
the model.

This paper presents a compact balanced antipodal Vivaldi antenna for medical microwave imaging applications. The antenna is supposed to operate in a matching
liquid with a high dielectric permittivity. The proposed antenna covers the frequency
range from 0.5 GHz to over 3 GHz. In the presented design, the substrate between
the tapered radiating parts of the antenna is removed and as a result the matching
liquid fills the resulting cavity. Thus higher directivity and narrower beam in the E-plane
are obtained. The results of the simulation are verified with the measurement of the
fabricated prototype.

A wideband, body contact, directive beam, circularly polarized, single arm, Archimedean
spiral antenna for radiometric temperature measurement inside human body in S-band
and an SAR (specific absorption rate) measurement method using a thermal camera
are described in this paper. A new approach of designing the spiral antenna based on
using the estimated effective permittivity of a multilayered microstrip line to design the
dimensions of spiral antenna is proposed. The purpose of using the effective permittivity is to set the position of the active region at the operating frequency (3.5 GHz),
which achieves the highest radiometric efficiency. Two simulation models are designed
to verify the reflection coefficient (S11 ) and SAR distribution. The reflection coefficient
(S11) of the fabricated antenna is less than -15 dB in the frequency range of 1-4 GHz.
A new multi-layered, low cost phantom is purposed to be used in SAR measurement.
Four layers of sponge soaked with (6 g/`) saline solution are used as a load for measuring SAR distribution of the fabricated antenna. The radiometric efficiency has been
estimated from simulation and measured SAR distribution. By assuming a target of 1
cm diameter, placed 1 cm away from the antenna within a human tissue compatible
environment, the highest efficiency is 1.4% at the operating frequency.

This paper presents a method to compensate CMOS process-, voltage-, and temperature (PVT) variations in a linear two-stage RF power amplifier (PA). The proposed
circuit technique mitigates bias point fluctuations caused by non-controllable uncertainties like wafer-dependent electron mobility, increasing die temperature due to substrate
self-heating, or supply voltage deviations. A scaled PA replica cascode circuit and a
over a wide range of PVT variations. As demonstrated by simulations and verified by
measurements, almost constant PA operating conditions over a temperature range
of more than 80°C and worst-case corners can be achieved. The proposed biasing
scheme has been implemented using a 28nm standard CMOS process. The PA is able
to deliver more than one Watt of RF output power at a peak power-added efficiency

analyzer (VNA). By combining the measured S-parameters of the 30x2 µm2 IMPATT
diode and simulated data of a short ended coplanar waveguide (CPW), an E-band
amplifier design flow based on SIMMWIC (Silicon Monolithic mm-Wave Integrated
Circuits) technology is as proof of concept presented. According to the simulation
results, the maximal gain of the designed amplifier achieved 34.4 dB at 67.8 GHz with
30 mA biasing current. With different biasing currents (20 ~ 40 mA) the avalanche
frequency of the embedded IMPATT diode could be varied from 71.3 GHz to 91.5 GHz.
This leads to an 8.6 GHz (62.8 ~ 71.4 GHz) dynamic tuning range of the amplification
frequency.

This paper presents a 60 GHz differential single-stage power amplifier IC with extrapolated 24.5 dBm output power and 12.9 % power added efficiency at 1 dB compression.
The circuit is based on distributed amplification with four parallel cascode stages and
power combination with a transformer. It shows a 3 dB gain bandwidth of 12 GHz from
51 GHz to 63 GHz with maximum power gain of 12.3 dB at 58 GHz. It consumes 600
mA from a 3.3 V supply and was fabricated in a 250 nm SiGe BiCMOS technology
with peak fT and fmax of 180 GHz and 220 GHz, respectively. The high linearity of the
circuit exceeds the capabilities of the available measurement instrumentation. A maximum output power of 16.5 dBm has been observed; extrapolation from the measured
data and matching simulated performance allow predicting an output power of 24.5
dBm at 1 dB compression. This value, to the best knowledge of the authors, would be
the highest reported to date for 60 GHz silicon power amplifiers.

This work adresses the temperature dependence of tunable components based on
inkjet-printed low temperature sintered Barium-Strontium-Titanate (BST) thick-film layers. To evaluate the temperature dependence, metal-insulator-metal (MIM) parallelplate capacitors were fabricated and characterized over a temperature range between
-60°C and 100°C. A relative capacitance shift below 8.7% was measured in the unbiased state and 1.4 % in the biased state. To evaluate the impact of this shift, a phase
shifter was fabricated and characterized within the same temperature range. Around
4.5 GHz a maximum figure of merit of 49.6°/dB was measured having a 87° phaseshift by applying 50 V tuning voltage. The relative phase-shift due to temperature is
below 4.7%, which shows promising results for wide temperature operation range.

with a transverse slot is used to guarantee the wideband performance. Electronic
equivalent circuit and analysis method is explained. The results of fabricated prototype agree well with the simulation. A phase shift of 90º with ≤ 1.5 dB insertion loss
and 36% relative bandwidth is achieved for 15 dB return loss. Amplitude and phase

This paper presents a novel concept for a planar cross-polarized transition to a 61 GHz
dielectric lens antenna. The transition to the circular waveguide antenna feed consists
of a combination of a microstrip line and a slot line. Each of these planar waveguides
excites the H11 Mode in the circular waveguide with a 90° polarization angle to one
another. The developed double layer transition topology was realized on a Rogers
5880 substrate employing the microstrip line on the top and the slot line on the bottom
layer. The concept was implemented and tested on a circular waveguide-fed dielectric
lens antenna for a 61 GHz radar system. Experimental results show a transition loss of
around -4 dB for the microstrip and -9 dB for the slot line feed with excellent crosstalk
suppression greater than 40 dB for the two polarization channels. The bandwidth of the
built cross-polarized transition is greater than 10 GHz. The results prove that the novel
transition concept is very well suited for compact, broadband and low cost polarimetric
millimeter-wave radar systems.

Transmission loss of E11x and E12x modes in suspended dielectric image guide is
measured at about 100 GHz. Commercial high-resistivity silicon is used as a low-loss
dielectric. Dielectric loss tangent of the silicon is measured separately at 100 GHz in
a rectangular waveguide resonator test fixture as (1.5±0.5) x 10-4. A copper metal
image guide resonator fixture of 22.83 mm length is used to determine transmission
loss of the image guide modes. Measured loss of E11x mode is within 14.6 dB/m to
22.1 dB/m. Measured loss of E12x mode is 3.24 dB/m to 3.72 dB/m. These loss values
are much lower than loss of typical substrate-integrated waveguide, they compare well
with loss of co-axial cable, and come close to the loss of air-filled rectangular metal
waveguide.

The conventional approach for radar level measurement of liquids in tanks is to perform
echo measurements in the free space above the liquid. In this paper, the alternative
approach of distance measurement using a bypass, which is a communicating pipe
connected with the tank, is discussed. The goal behind the presented work was to
optimize these systems in order to allow for high precision level measurements. It is
shown with a system theoretical model of the cylindrical bypass pipe that the given
dispersion might introduce severe systematical measurement errors. A time-variant
inverse filtering technique has been developed to compensate for the dispersion, and
the implementation in a Frequency Modulated Continuous Wave (FMCW) radar level
meter is discussed. For further optimization of the system’s performance, especially in
the case of weakly-reflecting liquids, a metallic float is used as an improved radar target.
The proposed concepts have been evaluated by means of measurements with a 5.7
to 6.7 GHz FMCW radar system for level measurement using a bypass pipe with an
inner diameter of 38 mm. Measurement results show that the distance measurement
error is decreased from +/-4.96 mm to +/-1.44 mm by means of the proposed inverse
filtering approach.

Civil, free space radar systems are often limited in bandwidth by regulatory authorities. Consequently, the accuracy of such radar systems is severely limited, which
reduces the usage in industrial applications. However, it is still possible to achieve
high accuracy, when an FMCW radar system combined with a phase evaluation algorithm is used. In this paper the accuracy requirements for the application of the phase
evaluation algorithm are derived. Furthermore, it is shown, that in certain cases an improvement of the SNR does not allow for a higher accuracy. To avoid this limitation, an
algorithm based on sweep time variation is presented. The objective of this algorithm
is to reduce accuracy degradations by unwanted reflections in FMCW radar systems.
Thereby, it becomes possible to use the combined frequency and phase algorithm.
68
GeMiC 2015 – Conference Programme
To evaluate the proposed algorithm, measurements with a 61 GHz ISM band FMCW
radar are taken and processed. The basic algorithm only achieves an accuracy of 1.8
mm in the measurement. With the new algorithm an improvement in accuracy of a
factor up to hundred can be achieved, as it allows for the combined frequency and
phase evaluation. The accuracy of the proposed algorithm is about 20 µm in the same
measurement.

This paper presents a 79-GHz micro-strip patch array antenna in a low-temperature
co-fired ceramics technology. The ceramic tape used has a low loss tangent (0.0013 at
79 GHz), a good shrinkage-control (with zero-shrinkage process), and it also enables
the photolithographic process for the outside layers of metallization. To verify the
performance of this material system for applications at 79 GHz, an array antenna
was designed with a radiation efficiency of 81 percent. A hybrid feeding-network was
chosen for the antenna. On the top layer the micro-strip patch antennas were used as
the radiating elements (with two layers of ceramic tapes as the substrate). They were
connected by the micro-strip lines (series-feed). A via guard-ring helps to suppress
parasitic surface waves due to the thick substrate. A vertically oriented power divider
(parallel-feed) keeps the mainbeam direction constant in a given frequency bandwidth.
The simulated and the measured half-power beam-widths are 9 degree and 70 degree
in the E-plane and H-plane, respectively. The measured bandwidth of 10-dB return
loss is around 4 GHz. The measured antenna gain (at WR12-flange) is 15.4 dBi.
This antenna has a geometry of 28mm x 3.2mm x 1.2mm and is suitable for 79 GHz
middle/short range radar applications.

best figure of merit for the given radar tachymeter application was selected. This approach can be successfully employed for sparse antenna array designs where multiple
constraints such as aperture size limitations or number and spacing of antenna array
elements are given. Distance and angle measurements taken with the implemented
optimized array show excellent results. The standard deviations in range and azimuth
were 8.6 mm and 0.1°, respectively for a range of several hundred meters.

Time: 14:10–14:10
In this paper a novel multiport measuring system is presented. It allows for the measurement of both reflection and transmission coefficients. The system features an
advantageous power distribution, which can be appropriately tuned in order to enhance the measurement accuracy. The system performance has been experimentally
verified by S-parameters measurements of a bandpass filter. The obtained results
are in a very good agreement with the values measured using a commercial VNA.
Moreover, the measurement results clearly show that the tunable power distribution
increases the measurement accuracy.

Description of nonlinear active devices is very complex, as it is a function of multiple input variables. Therefore, extraction of behavioral models based on traditional Designs
of Experiments, such as, factorial or Latin hypercube, may be unacceptably expensive
in terms of sample evaluation time. In order to limit the total number of samples required to obtain accurate behavioral models, the adaptive sampling technique may
be used. It is based on the surrogate models, which are extracted in every sampling
iteration. As nonlinear description consists also of many output variables, a common
synthetic quantity is proposed to limit the surrogate modeling cost. It is defined as a
total change of all the quantities. The approach was evaluated in simulations of a 0.15
um pHEMT model. The modeling accuracy is not impeded, while significant modelingcost reduction can be observed. Measurement examples will follow in the final version
of paper.

This paper describes application of the Surface Integral Equation (SIE) approach to the
analysis of scattering by different structures inside uniform waveguides and cavities.
The formulation of SIE makes use of the full four dyadic waveguide Green functions,
and the integral equation is solved by means of the Method of Moments (MoM). In
our work we show the methodology for obtaining the modal index number for different
Green function components by means of finding the convergence of modal series. We
also demonstrate effectiveness of this formulation by comparing the obtained results of
analysis for a given number of terms with solutions obtained by means of commercially
available software, which is based on the Finite Integration Technique (FIT).

First, a new waveguide transition is presented with the smallest size reported to date
yet excellent performance over a modest narrow bandwidth of 8%. This transition
method is then utilized to create an extremely high performance modification of the
Pickett-Potter dual mode feed horn. The result is the most compact possible feed with
a standard rectangular waveguide port yet the radiation pattern is fully symmetrical
and the backlobe is typically lower than -40dB. Unlike previous designs, this new feed
is the easiest to manufacture because it does not require stepped transformers or
multiple diameter cylinders.

The upsurge in the demand for high capacity communication links results in a rapid
growth in the field of optical fiber communication. Recent advances in satellite communication urge for the transmission of high frequency signals with minimum losses and
it is regarded that Radio-over-fiber (RoF) is the solution for such broadband analog
applications. Considering the many advantages offered by low-temperature co-fired
ceramics (LTCC) multilayer technology, it is promising to use this technology for passive alignment of an optical fiber to a laser diode, eventually hybrid-integrated with an
electro-optical modulator for microwave frequencies. In this paper, we analyzed the
necessity of efficient coupling of optical power into the fiber in an optical link based on
intensity modulation and direct detection. We also estimated the alignment tolerance
as +/-20 µm, which can be realized exploiting recent advances of LTCC technology.

Multiband and wideband monopoles constitute a research topic strongly motivated
by the growing frequency spectrum needs in the area of wireless communication applications. In this paper, a multi-band, multiple rhombus shaped, monopole antenna
is proposed as an alternative to the circular/elliptical disk/ring monopoles for broadband application. The simulation results are in good agreement with the measurement,
showing a multiband behavior with good radiative properties. The scattering parameter S11 exhibits four resonant frequencies close to f = 1.68 GHz, 3.38 GHz, 6.58 and
13.85 GHz, the measured gain is G = 3.1dB, 4dB, 6.3dB, 6.9dB, respectively.

Through the use of sensors to provide information about the vehicles surroundings,
driver assistance systems increase traffic safety. These sensors must not deliver wrong
data due to noise or external distortion. In FMCW Radar systems additionally a highly
linear ramp is essential. Hence nonlinear ramps have direct impact on the baseband
spectrum. Weak targets could be covered and therefore not detected.
This paper describes a method for evaluating the RF ramp linearity, based on analysis
of the baseband signal. Therefore the analysis is easier, as the baseband frequency
is only a few MHz depending on chirp modulation parameters and target distance.
The instantaneous frequency is measured, so that deviations from the ideal slope can
be detected immediately. Results are compared with simulations and high frequency
measurements with a commercial availably spectrum analyzer which calculates the
mean frequency deviation over a high number of ramps.

implementation. Additionally, a detection algorithm based on a speckle filter has been
tested for an exemplarily bulk solid scenario, and the influence of the penetration depth
of the bulk solid, the antenna beam width, and the filling level on the measurement error
has been analyzed. With a minimum signal to noise ratio of 10 dB, a measurement
error smaller 2 m has been obtained for the given scenario.

Time: 09:10–09:10
Mitigation of wind turbine interference (WTI) requires modelling of its impact on radars,
navigation systems and terrestrial radio links. A proper analysis of this interference,
in particular including the effect of diffraction by numerical field simulation requires a
high computational effort as the problem is electrically extremely large. We propose
a 2D Fresnel diffraction approach applied to tower and rotor of the wind turbine (WT)
that is including the effect of perfect conducting or real ground. In order to speed up
numerical integration an artifice using Babinet’s principle is used. The theory allows
for calculation of the time variant diffraction loss (or obstacle gain) and phase modulation. Results are compared with numerical 3D field simulations (Uniform Theory of
Diffraction).

Modern radar systems demand for high data rates to enable high resolution radar
imaging. Compressed Sensing (CS) has received great awareness in the last five
years, because CS enables a reduction of the sampling frequency by exploiting the
sparsity of the acquired signals and thereby allows to minimize the data rates. In this

paper, we describe a novel formulation for compressed sensing, where the dictionary is
represented by the signals in-phase (I) and quadrature (Q) components. Experimental

In this paper, the application of compressed sensing (CS) to pseudo random binary
sequence (PRBS) radar is analyzed. We show that under the principles of CS theory,
the sampling rate of the signal can be reduced without loss of resolution. CS theory
is used to reconstruct the signal of an UWB PRBS radar system with a bandwith
of 20 GHz, when the radar signal is undersampled with a sample frequency lower
than the Nyquist frequency. Finally, the performance of the reconstruction is evaluated
under the presence of static and moving targets.

This paper presents an off-line synchronization concept for the characterization of
integrated circuits with receivers operating in the Gb/s range. The concept relays on
the use of a programmable FPGA board with fast transmitters, a configurable delay
board and an undersampling test register at the receiver side. The synchronization
is done in two steps - in the first step the optimum sampling instant for each channel
is determined and set. In the second step a periodic sequence of ’01’ is sent on

them back over a slow feedback channel. With the feedback the sender can align all
channels to each other for signals with a period of two symbol lengths. This process
is repeated for logarithmic rising period lengths until the data period is longer than the
expected maximum relative delay of all channels.

Time: 09:30–09:30
This work addresses the optimization of Fractional-N Phase Locked Loops (Frac-N
PLLs) used to produce frequency chirps for Frequency Modulated Continuous Wave
(FMCW) radar applications. In a Frac-N PLL, we have two main clock domains which
are the reference and the divided clock domains. Clock domain crossings have to
be considered during chirp generation to produce highly linear chirps. Moreover, with
wideband chirps, integer divide ratio increments during chirp generation may cause
transient frequency glitches which also affect the chirp linearity if not taken care of.
In this work we propose techniques to address these issues in Frac-N PLLs. The
proposed techniques lead to highly linear wideband chirp generation and thus improve
the distance calculation accuracy by a factor of 2 and the distance calculation precision
by a factor of 1.5.

The PIC simulation of a Ka-band gyro-TWT using metal photonic band gap (MPBG)
waveguide as its RF interaction circuit is presented to study the electron beam-wave
interaction behavior. The MPBG guide is chosen as an interaction circuit to accomplish
the single mode operation of the amplifier by its mode selective property at short

demonstrated using "CST particle studio" code. The energy transfer phenomenon
from the gyrating hot electron beam to the propagating electromagnetic (EM) wave
has been studied. The PIC code predicts that the peak output power in the MPBG

The longitudinal beam shape properties, crucial information to operators, can be monitored in modern superconducting linear accelerators measuring the generated THz
radiation. Recent semiconductor technology may help to replace the single element
THz detectors (e.g. used at the ELBE accelerator in Helmholtz-Zentrum DresdenRossendorf (HZDR)) as well as the costly and bulky THz spectrometers. That’s why
we develop a simple integrated on-chip spectrometer in a GaAs technology that shall
be able to resolve 5 to 20 frequency points in the frequency range between 0.1 THz
to 1.5 THz. The core element is an integrated Schottky diode used as a power sensor
connected to on-chip antennas and filters. First results show that a multi-narrowband
antenna approach is very promising regarding complexity, sensitivity and selectivity.
This paper explains the design and presents the first simulation results for an onchip Schottky diode detector operating at 300 GHz that will be used on the on-chip

laminate for E-band (71–76 GHz) wireless photonic transmitters. The BT circuit enables proper biasing for millimeter wave photodiodes (mm-wave PDs) through the
RF-choke, and in addition, protects the hybrid integrated RF amplifier from being damaged by the DC voltage using the SCL DC-block. The planar RF-chock design is based
upon two slotted split-ring resonators (SRRs) and is integrated in the DC bias line in
order to prevent the leak of the RF signal into the voltage circuitry. Numerical results
of the DC-block section show that in the entire 71–76 GHz band, the return loss (RL)
is higher than 36 dB while the insertion loss (IL) is lower than 0.4 dB. The overall
performance of the complete BT circuit (DC-block and RF-choke) has been calculated
by the 3D full-wave electromagnetic field simulator based on the finite element method
(RL > 20 dB, IL < 0.6 dB and RF signal suppression in the DC bias line (IS) > 30 dB).
A via hole fencing surrounds the BT circuit to reduce the RF propagation losses into

Applications in radar systems and communications systems require very often antennas with beam steering or multi beam capabilities. For the millimeter frequency range
Rotman lenses can be useful as multiple beam forming networks for linear antennas
providing the advantage of broadband performance. The design and development of
Rotman lens at 220 GHz feeding an antenna array for beam steering applications
is presented. The construction is completely realized in waveguide technology. Experimental results are compared with theoretical considerations and electromagnetic
simulations.

It is well-known that mm-wave (millimeter wave) communications have high potential for future wireless broadband systems. However, there are important challenges
that need to be overcome when implementing those systems, both at the hardware
level and due to the hostile propagation conditions. This is especially important for
spectrally efficient communications based on large constellations, since the power
requirements are higher, as well as the amplification difficulties, specially for large,
dense constellations. In this paper we propose a multi-antenna transmitter combined
with a frequency-domain receiver for broadband mm-wave systems based on large
and dense constellations. Our transmitter is compatible with highly-efficient, low-cost,
strongly nonlinear amplifiers, while allowing spacial multiplexing gains.

In this paper two integrated auxiliary VCOs working at a center frequency of 34 GHz
cations are presented. The oscillators are using different realizations of the resonator
inductance which are compared in terms of quality factor and their influence on the
phase noise of the resulting oscillator output signal. The improvement in quality factor
at a frequency of 34 GHz between the oscillator using microstrip transmission-lines
and the oscillator using spiral inductors is simulated to be around 76% which causes
a simulated absolute improvement in output signal phase noise of around 4.5dB. Both
oscillators are realized as test circuits with which the difference can be measured to
be around 5dB proving the advantage of spiral inductors in terms of quality factor for

S17.2: A tunable Marchand balun at K band in Silicon Germanium (SiGe) technology

Naval Research Laboratory, USA
Time: 10:50–10:50
This paper presents the design of a switch-based, tunable Marchand balun at K band.
The tunability is achieved by using pass gate CMOS structures that ideally switch in
or out sections of the balun, thereby controlling its frequency response. The balun is
fabricated in a high performance SiGe BiCMOS process with standard 180 nm CMOS
technology. The ability to tune the response across a frequency range is demonstrated.
The balun is characterized in terms of mixed signal scattering parameters. Extensive
layout and simulations have been executed. The authors believe this is the first demonstration of a tunable balun using pass gate structures to change the lengths of the
balun windings in the high region of the microwave range.

Communications in the TV White Spaces are gaining increasing interest due to the
crowded frequency spectrum and rising demand for higher data rates. Especially the
dynamic access by Cognitive Radios is under research, offering a more efficient usage
of the spectrum. Due to the broadband nature of Cognitive Radio systems and the
presence of numerous strong interfering signals, the expectations on the linearity
of such systems are extremely hard. In this paper, an integrated CMOS broadband
highly linear fully differential LNA is presented, which enables a receive path to fulfill
the hard linearity requirements for broadband cognitive TV White Space applications.

The proposed LNA has a bandwidth of 300 MHz to 1 GHz and works without any
external components. It utilizes Complementary Derivative Superposition to cancel
third order intermodulation products and has an IIP3 of 19 dBm, CP1dB of -3 dBm
and Noise Figure of 2.6 dB within the TV White Space 470 MHz–790 MHz, while

This paper describes an available graphene process with respect to material properties and also the work in progress to complete the graphene process back-end
implementation to be MMIC-compatible. This process extension is critical to enable
fully integrated circuits and systems based on graphene transistors. A stable process
back-end is proposed, characterized and tested on both silicon and quartz substrates.
Based on this, a process cross-section is now available for EM simulations. A prototype chip of RF passive devices including spiral inductors, MIM capacitors and thin
film resistors, TFRs, is fabricated and measured on both substrates. On-wafer measurements of the fabricated passive devices up to 30 GHz show good agreement with
EM simulation results.

In the last few years, several low TCE LTCC materials have been developed for direct
wafer bonding to silicon. BGK, a sodium containing LTCC was originally developed for
anodic bonding of the sintered LTCC whereas BCT (Bondable Ceramic Tape) tailored
for direct silicon bonding of green LTCC tapes to fabricate a quasi-monolithic silicon ceramic compound substrate. This so-called SiCer technique is based on homogeneous
nano-structuring of a silicon substrate, a lamination step of BCT and silicon and a
subsequent pressure assisted sintering. We present a new approach for an integrated
RF-platform-setup combining passive, active and mechanical elements on one SiCer
substrate. In this context RF parameters of the silicon adapted LTCC tapes are investigated. We show first technological results of creating cavities at the silicon ceramic
interface for SiCer-specific contacting options as well as windows in the ceramic layer
of the SiCer substrate for additional silicon processing. A further investigated platform
technology is deep reactive ion etching of the silicon-ceramic-composite-substrate.
The etching behavior of silicon on BCT will be demonstrated and discussed. With the
SiCer technique it is possible to reduce the silicon content at the setup of RF MEMS
to a minimum (low signal damping).

A new, accurate, and fast approach for determining the temperature coefficients of
the thin film materials used in RF BAW components has been developed allowing
the precise modeling of BAW components at different ambient temperatures. The
presented method is based on the investigation of several resonance frequencies of
the resonators with different layer-stacks. The problem of determining the temperature
coefficients from broadband resonator simulations and measurements was formulated
as an overdetermined linear system of equations and solved by using the weighted
least square method. The presented approach has been verified by measurements.

In this paper, an approach towards the realization of a hybrid MEMS-CMOS RF oscillator module using the novel silicon-ceramic (SiCer) compound substrate technology is
described. Piezoelectric aluminium-nitride MEMS resonators with quality factors Q up
to 2,200 and resonant frequencies of 240, 400 and 600 MHz have been investigated
as frequency-selective elements. For RF-compatible hybrid-integrated assembly and
packaging, the SiCer compound substrate has been adapted, promising an efficient
integration of both, microelectronic and micromechanical devices, on a single carrier
substrate. Multiphysical circuit design and simulations using parametrized behavioural
MEMS models have been carried out, indicating stable oscillator operation at the design frequency. As one prospective application, such an oscillator module could form
part of a compact and power-efficient reconfigurable RF transceiver frontend in SiCer
technology, e.g., for mobile communications.

In this work we will present the capabilities of this monolithic SiCer (silicon on ceramics)
[1] compound by producing a parallel-plate RF-MEMS switch with flexible electrodes
and integrated coplanar waveguides. The series switch is one part of a LTE demonstrator and is developed in a heterogeneous process design. Here, the aim is to create
a low-voltage switch for mobile use with a simple layout. The modelling and simulation of the parallel-plate switch with flexible electrodes is carried out using ANSYS
(electro-mechanical simulation) and CADENCE (circuit simulation). To demonstrate
the advantages of the composite substrate, the coplanar waveguides for the RF-signal
and the control lines for the actuation of the electrostatic parallel plates of the switch
are processed by screen printing them on the LTCC tapes before sintering the composite. The relocation of the waveguides into the LTCC avoids damping influences on RF
signals by the silicon. An optimal process flowchart for modifying the silicon surface is
shown through which bond areas with a homogeneous bond strength between silicon
and LTCC are achieved and certain areas with cavities at the bond interface can be
produced.

Time: 09:45–09:45
Latest trends in nearly all domains of daily life require "smart" systems, meaning the
combination of sensors and actuators in different physical domains with an intelligent
signal processing. As market trends tend to more diversity as well as cheaper and
smaller devices, i.e. integrated, heterogeneous systems, shorter design cycles and
more flexibility hold the key for the development of such smart sensor/actuator systems.
Currently, the design flows for heterogeneous systems are separated. If seamless
RF-MEMS design methodology for monolithic and hybrid systems overcomes current
methodology and tool discrepancies in electronic and mechanical-design flows, further
capabilities can be made available. This paper gives an overview of requirements on
and solution approaches for an integrated design flow for RF-MEMS.

A theoretical approach for the specification of shunt MEMS switches suitable for TunMEMS switches designed with series metal-insulator-metal (MIM) capacitors at the
grounding plane of a CPW transmission line provide the basic design block for the
TMN. In the down-state, the MEMS switch makes an ohmic contact with the transmission line, as consequence, the down-state capacitance of the switch is dominated
by the MIM capacitors. The proper dimensioning of the MIM capacitors enables to
directly increase the capacitance ratio of the switch in order to operate at frequencies
below 10 GHz. Based on predefined CPW transmission line configurations on com-

14:00–15:40
Heikki Rekonen, Sales Director, AWR Group, National Instruments
Integrating RF circuitry onto printed circuit board (PCB) designs and correctly capturing the desired behavior for the digital, RF/microwave, and analog circuits within it is
just one of the many challenges that PCB designers face. To deal with this complexity
successfully, NI AWR Design Environment software enables a cross-platform design
flow with other PCB tool vendors such as Cadence, Mentor Graphics and Zuken to
name just a few. Marketed as AWR Connected, these cross-platform PCB flows offer
PCB designers a seamless solution that brings PCB or package layouts from major
EDA vendors into NI AWR software for microwave/RF circuit design as well as electromagnetic analysis. The flows works by extracting user-specified data from the PCB
vendor tool — conductors, nets, components, pins, substrate, material properties —
and producing an intermediate file that can then be quickly and easily imported into
the NI AWR Design Environment for additional circuit-level simulation with Microwave
Office and electromagnetic simulation with AXIEM and Analyst.

antennas under test (AUTs) a planar near-field measurement system offers beneficial
features like the possibility to mount the AUT at a fixed position and a simpler nearfield to far-field (NFFF) algorithm compared with algorithms required in cylindrical
or spherical near-field ranges. Nevertheless planar systems are like other antenna
measurement systems prone to many errors: The planar scanner, the probe or the
AUT can be misaligned, the positioning accuracy of the scanner can be too low or
coupling between AUT and probe can occur.
In this presentation the general working principle of planar near-field antenna measurement systems will be explained and compared to others. Afterwards issues and
weaknesses of planar near-field systems will be discussed and approaches to resolve
some of these problems will be pointed out. Goal of the presentation is to give a
general overview over the challenges of planar near-field measurements.

Markus Laudien, Lead Application Engineer, ANSYS Germany GmbH
Scenarios like antenna placement inside a complex geometry, an assembly of coupled
antennas or large antenna arrays are important parts of today´s RF systems. Due
to the complexity of these structures both the design process as well as the electromagnetic simulation of these systems are often challenging. Based on new simulation
methods like co-simulation, Domain Decomposition for finite arrays; FE-BI Hybrid
solver techniques and High Performance Computing ( HPC) the simulation procedure
can be strongly improved. Re-use of portions of the mesh can be applied to save
geometries of extreme differing size. Besides practical example cases like antenna
arrays the workshop will address the simulation approaches for antenna placement
on larger geometries or coupled antennas. A discussion will point out the advantages
and limitation of the simulation techniques for the different applications.

a complete radar system. This integrated framework provides a unique avenue for
both digital and RF engineers, as well as system engineers, to collaborate on complex

approach that provides an accurate model of the radar’s performance but also avoids
excessive resource (CPU, RAM) in order to achieve this goal. Furthermore, we show
how the algorithm can be reused in the prototype phase.
