一种电容加载宽带波导滤波器

A capacity-loaded broadband waveguide filter

依据波导滤波器的基本理论,借用电磁仿真软件,设计了一种电容加载宽带波导滤波器。仿真结果表明,该滤波器中心频率在19.5 GHz,相对带宽为21.5%,带外抑制好,矩形系数高。

According to the basic theory of the waveguide filter,a capacity-loaded broadband waveguide filter is designed via the electromagnetic simulation software.The simulation results show that with the center frequency of 19.5 GHz and the relative bandwidth of 21.5%,the filter features good out-of-band rejection and high rectangle coefficient.
