Abstract :
The paper addresses a CAD oriented closed-form expression for dispersive and conductor thickness based line parameters for symmetrical coplanar strip lines(CPS) on a finite-thickness dielectric substrate. Then, based on the analysis of CPS´s, elliptical coplanar strip line (ECPS´s) is studied. CAD oriented closed-form expression for the losses based on stopping distance for ECPS´s is obtained. The expressions are simple and accurate for microwave circuit designs and are applicable to both thin and thick conductors. Comparisons with published data from full-wave methods, experiments, HFSS and SONNET are presented to validate the expressions derived for all the cases. The average deviation of the model against the experimental result is 2.06 %.
