Bandwidth and Return Loss Enhancement of Microstrip Antenna using DGS

Abstract

This paper focuses on an inset-feedmicrostrip antenna (MSA) and enhancement of its Bandwidth and return loss using Defected Ground Structure (DGS).Two rectangular slot are used as DGS on the ground plane to get the desired results. The proposed antenna gives better result of bandwidth with DGS and return loss with DGS when compared with reference MSA without any DGS. This proposed resonating antenna is having frequency at 2.4 GHz where the bandwidth is around 290 MHz whereas the conventional antenna is having bandwidth of 76 MHz . The return loss of proposed antenna is found to be -39.11 dB General Terms Enhanced Bandwidth, Enhanced Return Loss, Electromagnetic Band Gap (EBG)
