Abstract :
A three line microstrip coupler on anisotropic substrate has been analyzed by using empirical and semi-numerical relations for obtaining strip-, gap and fringe-capacitances of the system. From these capacitances the coupler mode impedances, phase velocities and velocity equalization for various W/h and S/h values have been obtained. The results are within 5% of the ones obtained from vigorous numerical techniques.
