Abstract

Coplanar waveguides (CPW) are often suggested as an alternative to microstrip lines in GaAs monolithic microwave integrated circuits, especially when the active elements include planar diodes and GaAs FETs. This paper compares losses in coplanar waveguides with those in microstrip lines to provide a basis for the choice of the guide. Conductor and dielectric losses are lower in microstrip than in CPW when the substrate height is equal to the ground plane spacing in the CPW. When radiation loss is included and the ground plane spacing is allowed to increase in the CPW, the guides are comparable. The text of this paper is in digest form.
