頻率相關多重耦合傳輸線電容和電感之計算

Abstract

一個計算多重耦合傳輸線電容和電感矩陣的方法被提出。這個傳輸線系統包含了任意條傳輸線、一個接地平面、一個平行於接地平面的介質介面。一個半經驗模型的近似頻率相關參數可使用靜態的電容矩陣求得。在高頻的時候分散效應變得重要，這個模型對於電腦輔助應用設計將是有用的。

A method for computing the capacitance matrix and inductance matrix for a multiple coupled transmission line system has been presented. This system includes an arbitrary number of perfect conductors, one infinite ground plane, one dielectrics interface which is parallel to the ground plane. The closed-form expressions for the frequency-dependent parameters of this proposed semi-empirical model are derived in terms of the quasi-static capacitance matrix. The model should be useful in the computer-aided design of coupled microstrip structures at higher frequency where the dispersion effects become important.
