A Compact Microstrip Fed T Shape Patch Antenna with Swastika Ground

Abstract

A highly compact triple band patch antenna with dimensions 14×14×1mm3 is presented in this paper. The antenna is fed by a 50? microstrip line. The antenna mainly consists of T shape radiating patch and defected ground plane in swastika shape. The proposed antenna is simulated using HFSS simulator and return losses of the antenna at resonant frequencies of 13.1GHz, 15.8GHz and 18.8GHz are -22dB, -23dB and -37dB respectively. The bandwidth of the proposed triple band antenna is (12.7-13.4) GHz, (15.5-16.1) GHz and (18.4-19.2) GHz. The radiation pattern of antenna is bi directional and suitable for satellite and radar applications.
