摘要
本文提出了一种具有新型枝节加载谐振结构的超宽带滤波器,具有良好的超宽带特性,其3dB带宽为2.65GHz-10.95GHz,并且通带内3.18GHz-10.46GHz的范围内S11>20dB。通过仿真的结果可以表明使用本文采用的枝节加载形式,可以实现滤波器良好的的选择性以及阻带特性。
In this paper,a new method of ultra-wideband(UWB)bandpass iflters is developed based on stub loaded resonator,and has a signiifcantly widened passband.The iflter has a 3dB passband covering 2.65GHz-10.95GHz,and S11>20dB from 3.18GHz-10.46GHz in its band.THE simulated results are in good agreement,demonstrating that the UWB bandpass iflter has good in-band performance and wide upper-stopband by adopting the proposed stub loaded resonator.
