Design & Simulation of Rectangular & Circular Patch Antenna with Electromagnetic Band Gap Substrates

This paper presents the design and simulation of rectangular & circular patch antenna with Electromagnetic Band Gap Substrates (EBG) substrate using High Frequency Structure Simulator (HFSS). The two different configurations of broadband micro strip patch antenna, multi stacked rectangular patch antenna & multi stacked circular patch antenna are analyzed. Return Loss & Gain are performance parameter. The substrate used in these two configurations is RT Duroid having dielectric constant 2.2. The result calculated is return loss of rectangular patch & circular patch with EBG substrates are -13.98 dB & - 43.4437 dB and gain of rectangular patch & circular patch with EBG substrates are 5.7478 dB & 10.4954 dB respectively.
