Abstract

A microstrip patch antenna with two E-shaped stacked patches for UWB sectoral applications is proposed in this paper. The E-shaped patch antenna has an impedance bandwidth of about 34%. By adding a second E-shaped patch at the top of the first patch a bandwidth of 54% has been obtained. The characteristic dimensions of the second patch as well as the shift between the two patches have been optimized to achieve the ultra-wide bandwidth and radiation pattern stability over the whole band. The distorting nature of this antenna has been quantified using time domain characterization tools and the influence of the ground plane on impedance bandwidth and radiation has been studied.
