| 摘 要： | 本文根据变分原理,推导并计算出了波导纵向金属膜片取任意模式数时的等效网络。讨论了模式数的选取与等效电路精度的关系。利用这个等效电路,从传输参量的观点出发,导出了这种结构的带通滤波器的优化目标函数,提出了对所设计的带通滤波器进行计算机模拟的方法,并在2厘米波段设计了一只实验滤波器。实测结果与设计和模拟结果一致,最后给出了机加工误差对滤波器特性影响的模拟结果。

| Abstract: | In this paper, the equivalent circui parameters of E-plane metal insertsin a waveguide with arbitrary accuracy are investigated. The relationship betweenthe mode number chosen in calculation and the accuracy of circuit parametersare discussed. The object function for the design of bandpass filters by usingthis structure is given and the computer imitation technique for analyzing theperformance of a designed filter is presented. An experimental filter designedby using this method is tested and the results are in good agreement with theo-retical and imitated data. Errors in the attenuation of the filter caused by ma-nufacture are graphically shown. |
