Optimal Structure Determination of Microstrip Patch Antenna for Satellite Communication

Microstrip Antenna design has experienced more development in the past period of years and still is subjected to more development. There are different kind of microstrip antenna which can be used for many handheld devices and in the communication devices like satellite link, radar system, radio and cellular mobiles. In this paper the behavior of microstrip antenna is analyzed with two types of electromagnetic band-gap structure such as frequency selective Structure (FSS), and photonic band-gap (PBG) structure. The major characteristics of EBG structure are to show the band gap features in the suppression of surface-wave propagation. This aspect helps to give better antenna performance such as increasing the gain and reducing back radiation. In particular, the distance between EBG cells and the patch is free from the outside control of the cell period, which can be arbitrarily selected, and the final setup offers footprint reduction. With these factors the Gain, bandwidth, and the Voltage standing wave ratio (VSWR) are analyzed using the FEM based EM simulator HFSS.
