Ultra-wide band E-shaped patch antenna

Abstract

Broadband Microstrip antennas using E-shaped patch is reported. Here, a new design of E-shaped patch antenna is proposed for ultra-wide band response. A detailed parametric study explaining the effects of various patch parameters like, slot dimensions and their position, microstrip feed line dimensions and its position along the patch base is presented. The slots and feed line position in the patch optimizes the impedances over lower and higher order resonant modes which yields ultra-wide band response. A bandwidth from less than 1.5 GHz to more than 10 GHz is obtained in E-shaped patch design. The E-shaped patch yields bore sight radiation pattern with gain of around 1 to 2 dBi over most of the bandwidth.
