QUICK COMPUTATION OF [C]-MATRICES AND [L]-MATRICES OF GENERALIZED MULTICONDUCTOR COPLANAR WAVE-GUIDE TRANSMISSION-LINES

An enhanced spectral domain quasi-TEM analysis of generalized coplanar waveguide transmission lines (GCPWTL) is presented. The analysis star ts from the formulation of a convolution-type integral equation for th e electric field at the slots. Chebyshev polynomials including Maxwell singularities are used as basis functions to solve the integral equat ion by the Galerkin method, Fast and accurate quasi-analytical formula s are used to calculate the Galerkin's matrix entries, thereby signifi cantly reducing the involved CPU time and increasing reliability and a ccuracy. These features make this technique useful and competitive as CAD tool for coplanar waveguide designs.
