| 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。

| Abstract: | 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 waveguide E-plane filter,several narrowband and wideband band-pass filter are designed,the results agree well with those from HFSS or published. |
