Patch Antenna using Metamaterial Structure for Performance Specification

In this work, The drawback of Patch Antenna was impedance bandwidth. For this purpose, Rectangular microstrip patch antenna loaded with metamaterial structure has been proposed for improving the bandwidth by using CST MICROWAVE STUDIO in this paper. The proposed antenna is designed at a height 3.2 from the ground plane by using CST MICROWAVE STUDIO. The bandwidth of Microstrip patch antenna is 12 .1MHz and return loss is -10.36 dB at a band.The bandwidth of desired antenna is increased up 63.7 MHz at 2.865 GHz. The return loss of proposed antenna is reduced up to - 27.48 dB at 2.865 GHz. This proposed design has small size, easy to fabricate and better directivity.
