More Information
Summary:This article presents a compact circular-sectored microstrip antenna embedded with circular slots and a sectoral ground plane for enhanced bandwidth and applicable for UWB communications exhibiting an equivalent Fractional Bandwidth of 156.04% (2.5-20.25 GHz) and allows a compactness of about 79.15% using Rogers RT-Duroid 5880 as a substrate for lesser surface wave loss and attaining broader bandwidth. The gain of the antenna ranges from 1.85 to 6.10 dBi throughout the resonant frequency band and the results obtained from measurement are validated to justify the applicability of this antenna for various WLAN and Wi-MAX frequency bands.
