In this paper, we demonstrate the performance characteristics of the gain, surface waves, return loss of microstrip patch antenna with and without Electromagnetic Band Gap structure (EBG) for WLAN application. Electromagnetic Bandgap Structure (EBG) is mainly focused on overcoming the limitation of Microstrip Patch antenna such as low gain, excitation of surface waves etc., The Microstrip Patch Antenna consists of dielectric substrate with ground plane at one end and patch at other end whereas in EBG concept, additional EBG substrate with EBG cells are inserted in between ground and dielectric substrate. The simulation is done by using High Frequency Structure Simulator (HFSS).We have obtained gain of 14.2 dB for circular EBG and gain of 8.64 dB for rectangular EBG model respectively. Hence, we improved the efficiency of the antenna the EBG model.
