Analysis of cylindrical conductor-backed coplanar waveguides

CAD-oriented closed-form expressions are presented for calculating the quas istatic parameters of a conductor-backed coplanar waveguide (CBCPW) on a cy lindrical substrate. The effect of the curvature on the quasistatic paramet ers is also discussed by using the formulas derived by the conformal mappin g techniques. Furthermore, comparisons are made between the present results and the results available in the literature for CBCPW on a planar substrat e and microstrip on a cylindrical substrate.
