摘要

提出了一种计算微带传输线中对称两层不连续的散射特性的方法。该不连续结构由微带线的容性部分和其接平面上的梳状槽谐振器组成。该技术是基于横向共振方法。用复截面波导te波的基函数描述了梳槽谐振腔内的电磁场分布。结果表明，该结构能够设计出具有复杂散射特性的无源器件(滤波器)。后者包括与微带传输线的谐振相互作用的至少三个频率的带宽和宽阻带。

Analysis of Symmetric Two-Layer Discontinuity in Microstrip Line: Capacitive Section in Microstrip Line And Comb Slot Resonator in Ground Plane

A technique for calculating the scattering characteristics of a symmetric two-layer discontinuity in a microstrip transmission line is proposed. The discontinuity consists of a capacitive section of a microstrip line and a comb-shaped slot resonator in its ground plane. The technique is based on the transverse resonance method. Electromagnetic field distribution in the comb-slot resonator is described in terms of basis functions of TE-waves of a complex cross-section waveguide. It is shown that proposed structure enables a design of passive devices (filters) with a complex scattering characteristic. The latter covers both bandwidths and wide stop bands with at least three frequencies of the resonant interaction with the microstrip transmission line.
