Triple Frequency Micro Strip Patch Antenna Using Ground Slot Technique

Abstract

A micro strip patch antenna for wireless communications had proposed in this paper. The proposed antenna operates at three frequencies at 3.3GHz, 6.3GHz and 9 GHz which are mostly used for WLAN (C band) and radar, satellite communications (X band). Two rectangular slots are placed on the ground in order at achieve dual frequencies with good return loss less than -17dB and VSWR less than 1.4. The obtained results are simulated using ANSOFT HFSS software.
