摘要

本文提出了一种阶跃阻抗环谐振器多共振下的宽带带通滤波器。用经典的奇偶模方法分析了谐振腔的特性。结果表明，该滤波器可以在宽带上工作。为了演示，设计并制作了一个中心频率为2ghz、3db分数带宽(FBW)为96.7%的滤波器。实验结果与仿真结果吻合较好。

Wideband bandpass filter using open stub loaded square ring

A wideband bandpass filter under multiple resonances of stepped impedance ring resonator is proposed in this letter. The classical even- and odd-mode method is used to analyze the characteristics of the proposed resonator. It is observed that the proposed filter can operate at a wideband. For demonstration, a filter with central frequency at 2 GHz and 3-dB fractional bandwidth (FBW) of 96.7% is designed and fabricated. The experiments have good agreement with simulation.
