A multiple mode resonator is proposed to form an ultra-wideband (UWB) bandpass filter (BPF). The design consists of a ring resonator in the middle connected by interdigital coupled lines fed from both sides of the network. This ring resonator is studied to relocate its first four resonant modes with...
