ABSTRACT: The microstrip patch antenna is probably the most simplest and popular planar antenna. From the
appearance of the satellite communication we need to improve two key aspects in the communication systems: The
quality of the service as well as the costs. One of the ways to achieve these two aspects is the miniaturization of
communication components. This research is about design of planar antenna for satellite communication applications
using various performance improvement techniques. This project explores the capability of the microstrip antenna at a
higher frequency for the satellite communication.
KEYWORDS: microstrip patch antenna (MSTPA), Ku- Band
I. INTRODUCTION
An antenna is one of the most important elements in the RF system for receiving or transmitting signals from and into
the air as medium. The microstrip antennas have been object of study for researchers around the world with the purpose
to use them in the telecommunications with the objective of reducing size, cost and improving the quality in the
communications [1].
The microstrip antennas are designed in such a way that its structure dissipates the power in the particular direction in
form of radiation when applied with electrical signal as shown in Fig.1. The important advantages of these planar
antennas includes low profile, adaptability to the form of the structure, simple and cheap manufacturing and can work
on different frequencies and different polarizations [2]. However, common microstrip antennas are suffering from
limitations like narrow bandwidth, limited power capacity and tolerance problems.

The study includes the design of a single layer coaxial feed rectangular microstrip patch antenna operating at 11.7-12.5
GHz and 14.0-14.5 GHz in Ku band. It is expected that the design may reduce the drawback effects of the microstrip
antenna like low gain, narrow bandwidth and poor directivity.

LITERATURE REVIEW
With the development of the satellite technologies and its consequent miniaturization it appeared that microstrip
antennas giving the possibility of reduced costs, size and maintaining or improving the quality of the satellite and
terrestrial links. With its low cost and size it is possible carry out the satellite technology to more people around the
world.
A single layer coaxial feed rectangular microstrip patch antenna designed by introducing different slits on the patch so
that it can resonate at different frequencies in Ku-band [3].The location and dimensions of each slit determine the
resonance frequencies and also other antenna parameters [4]. The dual band can be achieved in antenna using different
pair of slits on patch [5].
III. DESIGN AND RESULTS
After taking account the design requirements such as bandwidth and dielectric constant, the microstrip patch antenna
was designed and optimized using HFSS V.13. The design begins with a single layer coaxial feed rectangular
microstrip patch antenna resonating around 15 GHz frequency. The radiating patch was implanted on Glass PTFE
substrate having 1.6 mm thickness. Design parameter analyses are calculated using fundamental equations from [1].

Design 3 : MSTPA with slit and notch on patch

On implanting one slit and notch on patch of conventional MSTPA, the antenna resonates at 12.1GHz
frequency which was convincing to our required band of operation.

Further design and optimization of conventional MSTPA has to be done by implanting different slits on patch for
introducing 14 -14.5 GHz frequency operation in the antenna with lesser harsh effects on previous design.
V. CONCLUSION
Simulation results show that by implanting slits and notches on the patch there is shift in resonance frequency. By using
these techniques, a compact shaped MSTPA has been introduced for Ku-band satellite applications. From this it is
concluded that it is also possible to build a planar antenna array to obtain much better and improved antenna parameters.
