The Generalized Transmission Line Equations are employed to analyze the circuit parameters of the microstrip lines. The static distributed capacitances and inductances of non-uniform microstrip lines are extracted. By comparing the differences between the port’s S-parameters respectively obtained by the extracted static circuit parameters using circuit method and by the Method of Moment directly, the applicable frequency range of the extracted static distributed circuit parameters can be found. The results show that the extracted static circuit parameters can be used in a frequency band from DC up to millimeter wave.
