Design of pentagon shaped microstrip patch antennawith metamaterialfor multiband application

Abstract

The need in today's wireless applications is to design antennas that are compact, robust and effortless to integrate with RF circuit components. Microstrip patch antenna is one such type which satisfies these requirements. But the two main performance parameters of an antenna namely the gain and the bandwidth are near to the ground for patch antennas. Usually the gain range of a patch antenna is 1–2dB. Most straightforward approach of increasing these factors involves the use of low dielectric substrate with increased thickness, but this inevitably leads to generation of surface waves. As a result, sensible substrate thickness has to be employed. In this paper pentagon shaped patch antenna with metamaterial on the substrate for multiband application is proposed. The analysis is done using Ansoft HFSS software version 15.0. The performance parameters analysed are bandwidth, gain and return loss. The proposed antenna design covers UWB range, C, X, Ku, K, Ka and a portion of V band.
