Fast computation of multiport parameters of multiconductor coupled microstrip lines

A fast approximate analysis method is presented for computing multiport parameters of uniform and nonuniform multiconductor coupled microstrip lines based on physical parameters considering dispersion and loss. A method for transient voltage analysis based on multiport S-parameters is also presented. The method is adequate for microwave and high-speed integrated circuit CAD software. Computed results for both S-parameters and transient voltages waveforms show good agreement with those by other methods or by measurement.<
