微帶線在有限接地情況之洩漏模傳播研究

Abstract

在本文中,我們探討有限寬度接地平板對微帶線第一高階模與主模的影響，並探討二種有限接地平板的特例:對稱結構與反轉結構。 另外，我們也將介紹一種新發現的洩漏模，並介紹此種洩漏模的電流分布以及色散特性。

The finite ground plane effects on the first higher-order mode and the dominant mode of a microstrip is presented. Two special cases of the finite ground plane (the symmetric structure and the reverse structure) are discussed in this thesis. A new additional leaky mode is reported. We introduce the current distributions and the dispersion characteristics of this mode.
