Characteristics of asymmetrical conductor-backed coplanar waveguides

Abstract

Abstract Analytical formulae for the quasi-TEM parameters of asymmetrical conductor-backed coplanar waveguides without or with upper shielding are presented. Their accuracy is verified through a comparison between the calculated and the available results for the specially symmetrical case. In addition, the line parameters of each asymmetrical conductor-backed coplanar waveguide are calculated, approximately based on simulating an asymmetrical coplanar line with two symmetrical ones. Good agreement is found for a wide range of geometric parameters.
