Design of Aperture Coupled Rectangular Microstrip Patch Antenna to Operate in S-Band at 2.25Ghz

In the recent years the development in communication system requires the development of low cost, minimal weight and low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies .This technology trend has focused much effort into design of micro strip patch antenna. The objective of this paper is to design an aperture coupled rectangular micro strip patch antenna which operates in S- band at 2.25GHz.This antenna is mainly intended to be used in many applications in communication systems such as satellite technology and military applications. The proposed patch antenna is designed and simulated on HFSS software. Ansoft HFSS employs the finite element method, adaptive meshing and brilliant graphics to give you unparalleled performance and insight to all of the 3D EM problems. After the simulation the antenna performance characteristics such as return loss, bandwidth, 3D and 2D radiation pattern, gain vs frequency plot are obtained.
