Design of a UWB Bandpass Filter with a Notched Band and Wide Stopband

A novel ultra-wideband (UWB) bandpass filter (BPF) is proposed and implemented in this article. The proposed UWB BPF has a highly rejected notched band and improved out-of-band performances. It is composed of two cascaded interdigital hairpin resonator...
Research into ultra-wideband technology has risen dramatically since the US Federal Communications Commission (FCC) authorized the frequency band of 3.1 to 10.6 GHz for commercial purposes. 1 A bandpass filter is a key component of a UWB wireless communication system. Many BPFs have been developed based on various kinds...
