Abstract
CAD-oriented closed-form expressions are presented for calculating the quasistatic TEM parameters of asymmetrical coplanar waveguides (ACPWs) with finite ground planes. The effect of the ground-plane width on the quasistatic parameters has been investigated by using the formulas derived by the conformal mapping techniques. Comparisons have also been made between the present results and the results available in the literature for both the conventional coplanar waveguide (CPW) and ACPW. The results are in good agreement with the results derived by the conformal mapping technique and the spectral-domain method. It has been shown that the present expressions can also be used for calculating the quasistatic parameters of both symmetric and asymmetric CPWs with finite and infinite ground planes.
