摘　　要：利用复功率守恒法(CCPT)分析了波导纵向E面金属插片,得到了插片基本单元的广义散射矩阵公式。针对经典低通滤波器原型,不能获得较宽带宽的带通滤波器的设计,本文基于半波分布阶梯阻抗滤波器原型求得归一化阻抗倒置器值,编写了波导E面带通滤波器CAD程序,设计了几只宽带和窄带的带通滤波器,所得结果与其它方法吻合。Waveguide E-plane with metal diaphragm is analyzed by Conservation of Complex Power Technique. The Generalized scattering matrices are calculated. For narrowband design with a low-pass filter prototype, based on a half-wave distributed step-impedance filter prototype, the normalized impedance inverter values are determined. CAD program is developed for the wavegnide E-plane filter, several narrowband and wideband band-pass filter are designed, the results agree well with those from HFSS or published.
