Abstract: A numerical analysis is presented in terms of finite element of hybrid-mode propagation characteristics in microstrip transmission lines, which include characteristics impedance, velocity ratio, dispersion characteristic and the effect of strip thickness. The results of calculation are compared with previous approximate calculations. It is shown that the finite-element method is an efficient numerical analysis for microstrip transmission lines. -
