CAD models of losses for elliptical and circular cylindrical CPW on multilayered dielectric substrates

The paper addresses a CAD oriented closed-form expressions for the losses based on stopping distance for different configurations of elliptical CPW (ECPW) and cylindrical CPW (CCPW) on a finite-thickness multilayered dielectric substrates. The analysis of the structures has been done using conformal mapping and SLR technique. Comparisons with 3D-EM simulators are presented to validate the expressions between 1 GHz – 60 GHz. The average deviation of the model against the comparison is 2.78 %.
