Abstract
A novel ultra-wideband(UWB) bandpass filter with dual notch-bands and wide stop-band is proposed. The designed UWB BPF is cascading a coupled simplified composite right-left-handed (SCRLH) resonator and a ring slot resonator (RSR). The SCRLH resonator creates two different notch-bands. And the RSR unit suppresses the higher-order harmonics at the upper stop-band. The UWB BPF demonstrated good insertion/return losses and out-of-band rejections in simulation.
