Abstract

A novel triple band-notched slot planar inverted cone antenna (SPICA) is proposed for UWB applications. The unnotched ultrawideband antenna is composed of a cone shaped radiating patch and a wide circularly slot on the ground plane. To obtain anti-interference characteristics, an elliptical complementary split ring resonator (ECSRR) was etched in the radiating patch and a parasitic V shaped strip was added adjacent to the upper edges of the cone shaped patch. This will result in triple notched bands at WiMAX, WLAN and X band satellite communication downlinks. The results show the antenna has a wide impedance bandwidth of 140% for SWR <; 2 from 2.2 to 12 GHz with triple undesired bands (WiMAX, WLAN and X-band satellite communication downlinks) rejected. Other advantages, such as stable omnidirectional radiation patterns, easy fabrication as well as compact size make the design applicable to UWB applications.
