Modified Peano-Gosper Fractal Geomatry Based Wideband Microstrip Patch Antenna Design Analysis

Sarbjeet Singh, Suman

Abstract: In this paper, the modified Peano Gosper curve has been applied on the perimeter of square patch of microstrip antenna to obtain new antenna design. The proposed antenna was designed, fabricated and characterized on a 1.6 mm thick FR4 substrate. The proposed antenna has dual band characteristics for 3.43 - 3.655 GHz and 3.97 - 7.12 GHz band with maximum negative return loss of -40 dB at 4.33 GHz. Wide bandwidth was achieved by placing an air gap between the patch substrate and ground plate. The proposed antenna has wide bandwidth of 3.15 GHz and peak gain of 1.90 dB.
