摘　　要：详细介绍了一种适用于毫米波段的E面膜片波导带通滤波器的精确设计方法。首先采用模式匹配法分析了矩形波导内的E面膜片，获得了相应的等效集总电路参数；随后运用综合法设计了一款工作于Ka波段的波导带通滤波器；最后加工了测试样品，实测数据与理论计算结果吻合良好，表明该方法具有令人满意的精确度。目前，利用所述方法设计的带通滤波器在某通信系统中得到应用，并取得了良好的效果。A kind of rigorous design method of band pass filter with E-plane strip mounted in wavegnide is presented. Firstly, E-plane strip mounted in wavegnide is analyzed by employing mode matching technique and, the equivalent lumped circuit is obtained; Secondly, a wavegnide band pass filter operating at K-band is designed; Finally, the sample is manufactured, the measured results agree well with the calculations. At present, the filter is applied to a certain communication system and, good effects are achieved.
