摘　　要：多导体传输线的串扰分析是信号完整性分析中经常遇到的问题。多导体传输线之间的串扰问题与传输线之间的分布参数存在密切联系,其分布参数分为分布电容矩阵和分布电感矩阵两个方面。本文采用有限元方法对由五条导线构成的一个多导体传输线结构进行建模,计算了该结构的单位长度分布电容矩阵和单位长度分布电感矩阵,分析了该结构中的串扰现象,通过与文献中结果对比,计算结果一致性很好,方法可行有效。The Crosstalk analysis of multi - conductor transmission lines is critical to the signal integrity. It is closely related to distributed parameters of multi - conductor transmission lines. In this paper, the finite element method is used to calculate the distributed capacitance matrix and the distributed inductancema- trix of the multi - conductor transmission lines, whichis formed with five conductors in a single - layered dielectric medium. The results are compared with the work of the previous literatures. They are in good a- greement, and the method is feasible.
