THEORETICAL CHARACTERIZATION OF COPLANAR WAVEGUIDE USING CONFORMAL MAPPING

Mukesh Kumar, Rohini Saxena, Anil Kumar, Pradyot Kala, Reena Pant

Abstract

In this paper we present the estimation of the characteristic impedance and the effective dielectric constant of Coplanar Waveguide(CPW) using conformal mapping theory and performances are predicted using theoretical analysis. Numerically efficient and accurate formulae based on the conformal mapping method for the analysis of coplanar waveguide structures are presented. The analysis formulas for Coplanar Waveguides are derived and verified with Matlab. Characteristic Impedance of CPW for different dielectric material as well as for different thickness of the substrate material is under consideration in this work. With the help of CPW transmission techniques, substantial amount of efficiency has been achieved.
