IMPROVING THE PERFORMANCE PARAMETERS OF MICROSTRIP PATCH ANTENNA BY USING EBG SUBSTRATE

Gaurav Kumar Sharma, Narinder Sharma

Abstract: The objective of this paper is to analyze the performance of electromagnetic band gap (EBG) antenna for base station applications through simulation. The proposed analysis is carried out using the high frequency structure simulator (HFSS). In our method, to overcome several intrinsic limitations of patch antennas such as constrict bandwidth, low gain, excitation of surface waves, the EBG concept is applied. The patch antenna and patch antenna surrounded by the EBG cells are characterized in terms of return loss and radiation pattern in an anechoic chamber.

Keywords: Microstrip patch antenna, electromagnetic band gap structure, bandwidth, gain
