Computer aided design oriented analytical formulas were presented for determining the characteristic parameters of multilayered cylindrical coplanar waveguide (MCCPW) with asymmetrical slot widths. Closed form expressions were derived for evaluating the effective relative dielectric constant and characteristic impedance by using a sequence of conformal transformations. The effect of the asymmetric slot widths of MCCPW on the quasistatic parameters were investigated. And comparisons were also made between the present results and the results available in the literature for the cylindrical CPW. The derived formulas show good accuracy.
