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

Abstract

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