摘　　要：对阶梯阻抗谐振器的谐振特性等进行了分析和计算。设计了一种新型缺陷地结构双T形微带带阻滤波器和一种新型缺陷地结构双H形微带带通滤波器,对其滤波性能进行了仿真计算。该文设计的滤波器具有宽带宽,高衰减,结构简单等优点,可供射频电路应用参考。In this paper, resonant conditions, resonant performances etc. of stepped-impedance resonator are computed and analyzed. A novel double T-shaped microstrip bandstop filter with DGS and a novel double H-shaped microstrip bandpass filter with DGS are proposed, and their performances are simulated. The filters designed in this paper have advantages such as wide bandwidth, high attenuation, simple structure, easy manufacture and low cost etc. , and can be applied in RF circuit.
