The E-shaped patch to enhance the bandwidth of printed monopole antenna for UWB

Abstract

In this Paper, a printed monopole antenna (PMA) with an E-shaped patch has been proposed for UWB applications. The conventional PMA is designed with the center frequency of 6.77 GHz with wide bandwidth. The bandwidth is enhanced to cover the UWB band by modifying the rectangular patch in to E-shape. The rectangular slots in E-shape generates the resonating modes and it will help to enhance the bandwidth to cover UWB. The simulations demonstrate more than 3.99 dBi peak gain with UWB bandwidth (3.1- 10.6) GHz and excellent monopole radiations in both principal planes. A prototype has been fabricated using commercially available low-loss dielectric material FR4 (glass epoxy) with dielectric constant (εr)= 4.4. The experimental validation of predicted simulation results is under process.
