Current distribution and dispersion analysis for different dielectric substrates of microstrip line by using SONNET

This paper we mainly emphasize on simulation & synthesis of micro strip line by using powerful simulation tool sonnet. Many researchers have investigated the dispersion characteristics current distribution of micro strip lines at different higher frequency range. This paper we analyzed the micro strip line with characteristic impedance 50Ω at frequency range 1 to 20GHz for FR-4, Roger 3001, Teflon, Polyimide and Taconic RF-30, 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 current distribution on the software tools.
