Abstract
A coplanar waveguide- (CPW-) fed dual-band-notched antenna with sharp skirt selectivity for ultrawideband (UWB) applications is presented. The proposed antenna is composed of a radiant patch with a C-shaped slot and a C-shaped stub on the back surface of the substrate. By using the C-shaped slot and the C-shaped stub, dual-band-notched characteristics can be generated. In this way, a more practical and effective approach to design an UWB antenna with sharp notched-band-edge selectivity is developed. The measurement results show dual notched bands of 4.96–5.42 GHz and 5.71–5.91 GHz, which can reject the interference between IEEE 802.11a bands (5.15–5.35 GHz and 5.725–5.825 GHz) and UWB systems. The fabricated antenna shows good omnidirectional radiation patterns with acceptable gain and group delay.

Ultrawideband (UWB) technology has recently become one of the most promising candidates for short-range highbandwidth indoor and outdoor wireless communications systems
Since the UWB systems occupy an extremely wide band from 3.1 to 10.6 GHz, it is necessary to reject the interference with the existing wireless local area network (WLAN) for IEEE 802.11a operating at 5.15–5.35 GHz and
