Dispersion Analysis of a Microstrip Line at Higher Frequencies by Using Sonnet and Matlab

Abstract

This paper we mainly emphasize on simulation & synthesis of microstrip line by using powerful simulation tools like sonnet and matlab. Many researchers have investigated the dispersion characteristics of microstrip lines at different higher frequency range. This paper we analyzed the microstrip line with characteristic impedance 50Ω at frequency range 1 to 20GHz for Alumina, Gallium Arsenide and Silicon substrate materials. All parameters of the microstrip lines are exactly determined from the empirical formula of microstrip line. Here we compare the results of the dispersion formulas on the software tools.
