摘要
针对一般E面波导滤波器结构存在阻带特性较差的缺点,本文对E面双条带结构进行了全面的分析。这种结构具有阻带特性好的优点。文中给出了简明的矩阵公式,并进一步提出了改善E面结构带外特性的可行方法。利用所得公式,分析和设计了Ka波段E面双条带波导滤波器,实验数据和理论分析吻合较好。
In contrast to conventional E-plane structure, E-plane dual strip integrated circuitfilters combine the advantages of low cost, high stopband perforrnance. After analyzing the structure, a set of concise rnatrix forrnulae and a practicable way to irnprove the stopband attenuation ofthe E-plane filter are presented in this paper. A Ka-band E-plane dual strip waveguide filter isdesigned by using these formulae. The numerical results agree well with the experimental data.
