摘要: In this paper, an ultra-wideband (UWB) bandpass filter (BPF) is proposed, which formed by interdigitated structure and a defected ground structures (DGS) four short-circuited branches. This has sharp selectivity due to two zeros at low frequencies. One of the low-frequency 1.2 GHz other 3.8 GHz. The proposed working frequency range 3.85 11.83 center 7.89 was designed using RT/Duroid 5870 medium with thickness 0.862 mm. total fractional bandwidth 101%.
