摘　　要：介绍了一种Ka波段E面膜片波导带通滤波器。首先对该滤波器等效电路进行理论分析,并利用CST软件进行仿真优化,给出仿真曲线和测试曲线,仿真结果和测试结果吻合良好,相对宽带为2%,带内损耗小于2 dB。该滤波器具有Q值高,体积小,容易加工和集成等优点。A Ka-band E-plane septum waveguide band pass filter is proposed. Through the analysis of filter equivalent circuits, the filter is designed and simulated based on Computer Simulation Technology（CST）. The simulation and measurement curves are obtained, which agree well with each other. With the fractional bandwidth of 2%, and the insertion loss less than 2 dB, the filter has the advantages of the high Q factor, small size, and simple fabrication etc.
