摘要: A new microstrip ultra-wideband (UWB) bandpass filter (BPF) with dual notched bands based on E-shaped resonator is proposed in this paper. The basic UWB BPF composed of lines and rectangular patch mutiple-mode (MMR). To achieve bands, the used coupled to main transmission line BPF. has passband from 2.9 GHz 10.6 GHz, first band designed 3.5 3.9GHz second 6.7 7.3GHz, both which have less than 0.8 dB magnitude insertion loss greater 20dB return loss. simulation results show that good wideband filtering performance sharp rejection skirts outside passband.
