Abstract :
The paper addresses a CAD oriented closed-form expressions for the losses based on stopping distance for semi-ellipsoidal coplanar waveguide (SECPW) and semi-circular cylindrical coplanar waveguide (SCCPW) on a finite-thickness dielectric substrate. The analysis of the structures has been done using conformal mapping technique. The expressions are simple and accurate for microwave circuit designs and are applicable to both thin and thick conductors. Comparisons with 3D- EM simulators like HFSS and CST are presented to validate the expressions between 1 GHz-60 GHz. The average deviation of the model against the comparison is 2.48 %.
