Abstract

In order to avoid the interferences from systems operating over 5-6 GHz, a novel design of compact-size wideband notched antenna is presented in this paper for ultra-wideband (UWB) applications. The reference antenna consists of a half circle shaped ground plane and a half circle shaped radiator with a half elliptical cut. A wide notched band is achieved by using an extended strip and a loaded strip. It has advantages of a wide impedance matching from 3.1 to 10.6 GHz and a good band-notched performance in 5-6 GHz with gain suppression better than 10 dB.
