Synthesis formulas for conductor‐backed coplanar waveguide

Abstract

Abstract Simple and accurate formulas are presented for the synthesis of conductor‐backed coplanar waveguide (CPW). These formulas are derived by applying function approximation and curve‐fitting technique to the respective quasi‐static analysis results. The results obtained from these formulas are compared with the results of quasi‐static analysis and experimental works available in the literature. Average percentage error is found to be better than 1% for 1086 conductor‐backed CPW samples having different electrical parameters and geometrical dimensions. © 2008 Wiley Periodicals, Inc.
