A Compact Slotted Patch Antenna with Enhanced Gain Antenna for Satellite Application

Abstract

ABSTRACT

A compact patch antenna is designed using high frequency structure software. The rectangular shaped antenna slotted T shape slots in the antenna. The proposed antenna is designed on FR-4 substrate with dialectic constant 4.4. After analyzing, the return losses and gain of antenna is calculated. The proposed antenna is analyzed at two frequency 29 GHz and 31.5 GHz. The calculated result for return loss of multiband patch antenna is -33.59 dB and -26.2588 and gain of patch is 7.5705 dB and 8.7085 dB respectively.
