摘　　要：本文用直线法对椭圆微带线的色散特性进行了研究,导出了色散特性方程.在共焦椭圆情况下,当频率较低时,本文结果与准TEM波分析结果趋于一致。同时给出了两种微带结构的色散曲线。In this paper, the basic principle of the method of lines is extended to the research of dispersion characteristic of elliptical microstrip lines using modified boundary conditions. A dispersion characteristic equation is derived. The results of this method are in agreement with those calculated in qu-asi-TEM case in low frequency for confocal ellipses. At the same time, the dispersion characteristic curves of two kinds of special microstrip lines are given.
