This paper describes the application of the complex image concept to the quasi‐TEM analysis of multiconductor coplanar waveguides (CPW). Some troubles that arise when this technique is applied to conductor backed structures are addressed and solved. A Galerkin scheme is used to solve the integral equation for the slot electric field in a very efficient manner: The employed basis functions account for edge singularities—so that the Galerkin matrix size is kept small—and lead to quasianalytical expressions for the matrix entries. In this way, we have developed a very fast quasistatic solver for arbitrary CPW geometries that is suitable for CAD purposes. © 1998 John Wiley & Sons, Inc. Int J RF and Microwave CAE 8: 405–416, 1998
