摘要
采用混合S参数法研究了入射波和集总电源共同激励下微带线的终端响应,对于微带线上的传输线模式波和天线模式波的计算采用了Galerkin积分方法,避免了采用广义函数束方法 (GPOF)从仿真结果中提取信号的过程,从而简化了计算步骤,减少了计算时间;通过与电磁仿真软件HFSS仿真结果的比较,验证了该方法的正确性;并采用混合S参数方法计算了不同微带线参数对耦合效应的影响,研究表明,当微带线长度变长,宽度变宽,介质基板厚度变厚,介质基板相对介电常数变大时,耦合效应变强,其中耦合效应受长度影响最大。
A hybrid S parameter is used to study the terminal response of microstrip line subject to arbitrary plane wave and port excita- tions. The forced wave and modal wave are calculated by Galerkin＇ s solution. Compared with traditional method GPOF, It greatly improve the computational efficiency. Correctness of this method is validated by the comparation with the full--wave simulate software HFSS. The influence of different parameters on the mierostrip line terminal was investigated using the hybrid S--parameter method. The results show that, the coupling effects will be stronger when the microstrip line is longer, wider, thicker and the relative permittivity is biger, and the in- fluence of longitude is strongest.
