Optimization of Coupled Transmission Line Parameters Based on Mode Impedance Extraction

Multi-conductor transmission lines are important channels for the propagation of electromagnetic energy and signals and are an important part of electronic systems. The odd-even mode impedance is an important parameter of coupled microstrip lines. In this paper, an RLGC parameter extraction algorithm is learned to improve the efficiency of transmission line parameter extraction; a sensitivity matrix is established for error analysis and optimization of transmission line parameters. By combining the above, the optimization of the structural parameters of the coupled microstrip line is realized according to the target impedance value by automatic iteration in order to obtain the required structural parameters of the coupled line. And the above algorithms are packaged into a standalone executable program in Python.
