摘要

研究了一种中心金属芯的新型矩形空腔的结构。利用有限元法确定了内部尺寸(芯半径)对该同心谐振器的H-和e -两个最低模的本征频率和电磁场本征函数的影响。此外，研究了同轴输入输出矩形同心谐振器在ka波段的散射矩阵参数。指出了在此基础上实现小型带通滤波器的可能性。分析了影响通带反射系数的因素。

Investigation of Parameters of Rectangular Concentric Resonator

Structure of a new type cavity of rectangular shape with a central metallic core is considered. The influence of internal dimensions (core radius) on the eigenfrequencies and the eigenfunctions of electromagnetic field of the two lowest H- and E-modes of such concentric resonator are determined with the help of the finite element method. Moreover parameters of scattering matrix of rectangular concentric resonator with coaxial input and output ports are investigated for the Ka-band. Possibility of realization of small-sized bandpass filter on its basis is shown. Factors influencing on the reflection coefficient in the pass band are analyzed.
