ABSTRACT
A UWB system operates from 3.1 to 10.6 GHz. In such a wide band, the UWB systems can get interference from existing narrow band systems such as WLAN systems working in 5.15 to 5.35 GHz, 5.725 to 5.825 GHz bands, WiMax operating at 3.5 GHz, and satellite communication bands operating around 8 GHz. Thus, it is desirable to have a notch at those bands in the UWB band-pass filter (BPF) to avoid interference.
