摘　　要：本文利用矩量法和一般的网络分析技术分析了平面电路中各种E面膜片不连续性。通过引入广义波导概念,自然地考虑了膜的厚度效应,应用分析结果,设计和试制了2个W波段E面带通滤波器,实验结果与设计指标符合较好。Various E-plane septa discontinuities in planar circuits are analyzed by the moment method combining with generalized network analysis technique. By introducing an i-dea of generalized waveguide, a unified treatment of such problems is realised, and the effects of the septa thickness are taken into account. A general formulation for calculating the equivalent circuit parameters of the discontinuites is derived. Based on the present analysis,E-plane bandpass filters are designed and fabricated in W-band. The experimental results agree well with the theoretical predictions.
