腔体内单极天线的电流分布及输入阻抗的研究

The Study of the Currents and Input Impendance of a Monopole Antenna in a Rectangular Cavity

本文利用矩量法与并矢格林函数相结合,研究了腔体内单极天线(或探针)的电流分布及输入阻抗。通过选择分段正弦基函数,不但使矩阵阶数大大减小,而且改善了矩阵元素级数的收敛性。本文的数值结果还给出了腔体内有耗介质对输入阻抗的影响。

The study of the currents and input impendance of a monopole antenna(probe) in a rectangular cavity is given by using moment method and Dyadic Green's Functions. The order of the matrix is lower, and the convergence of the series of its elements are accelerated by using the piecewise sinusoidal base functions. The effect on the lossy medium on the input impedance is also given.
