抄録

An Ultra-wideband (UWB) bandpass filter (BPF) based on an elliptical open stub-loaded resonator (EOSLR) and dumbbell-sided cross-circle (DSCC) defected ground structure (DGS) is proposed in this paper. The measured results show that the 3 dB bandwidth of the filter is 3.49 ∼ 11.04 GHz, the skirt factor (S.F) is 0.844, the upper stopband rejection is greater than 20 d B at 11.70 ∼ 26.80 GHz, and the stopband width is 15.1 GHz. The proposed filter has the advantages of high selectivity and extremely broad upper stopband and it can be applied in UWB Wireless communication system.
