Triple Band Reflector Based Square Shaped Microstrip Patch Antenna With Band Gap Structure For Uwb Application

Abstract

In this proposed paper Ultra Wide Bandwidth (UWB) antenna with Deflected Ground Structure (DGS) for wireless communication is presented and analyzed. Our proposed antenna design is consisting of L inverted L slots and U-slits on the radiating patch and Band Gap Structure (BGS) at the ground with triband frequency operation in various wireless communications. This triband antenna is designed using the FR4 substrate with permittivity level of 4.4. The proposed antenna dimension is 22.7 x 22.7mmwith gain of 3.2 dB. The antenna proposed in this paper operates at triple bands centered at 3.7 GHz, 6.7 GHz, and 9.5GHz with corresponding return loss of -11.8dB, -20.1dB and -13.0dB.
