Abstract

A novel triple-band notched circular ultrawideband (UWB) antenna with a band rejection characteristics at WiMAX, WLAN and C-band is presented. A design involving two concentric G-shaped circular slots etched on the circular patch structure and a U-shaped slot on the CPW transmission line is used to reject and control the notched frequency bands. The proposed antenna has good UWB characteristics from 3-12 GHz with VSWR <; 2, except frequency bands of 3.3-3.6 GHz, 3.7-4.2 GHz, and 5.1-5.9 GHz. The designed structure exhibits good radiation characteristics over the desired band and is a good candidate for UWB applications.
