Abstract :
A CPW-Fed ultra-wideband antenna with dual notch-band using embedded slot resonator is presented in this paper. Stub-loaded open-loop resonator can be utilized to design compact dual-band bandpass filters with improved out-of-band rejection characteristic. When the stub-loaded open-loop resonator embedded into the feed line of the UWB antenna and transformed into slot resonator, dual notched band property is obtained. By adjusting the parameters of the embedded slot resonator, the dual band-notched UWB antenna can be adopted to minimize the potential interference between the UWB system and the narrow band systems, such as systems in the WiMAX/WLAN bands.
