摘要：
In this paper, an ultra-wideband bandpass filter was accomplished. The proposed filter is constructed by using a coupled three line microstrip structure and a stepped-impedance open stub (SIOS), connected at the symmetrical plane of the filter to increase the passband selectivity. The measured result shows the centered frequency of the passband at 3.97GHz with low insertion loss of 0.48 dB and wide 3-dB fractional bandwidth (FBW) of 45.3% from 3.1GHz to 4.9GHz. Two transmission zeros are obtained near the passband at 2.72GHz and 5.71GHz with good rejection level of 50.3 dB and 60.5 dB, respectively. The measured results of the fabricated ultra-wideband bandpass filter also show a good agreement with the simulated ones.
