A Study in Characteristic Impedance of a Microstrip Transmission Line by COMSOL Model

Abstract

In this paper, a sample of microstirp transmission line has been presented. Microstrip transmission lines have been widely applied in microwave
purposes. The characteristic impedance of this sample was studied. This characteristic is an important parameter, especially in impedance matching.
Then the equations are proposed to realize the effective parameters on the characteristic impedance. By ADS software these parameters are validate
and finally, A COMSOL model for a microstrip is proposed. The electrical field through a microstrip is plotted and magnetic flux density through a
microstrip sample is presented. The results by this modeling method, proof the ADS simulations and the equations.
