A NOVEL WIDEBAND TRANSITION BETWEEN A CONDUCTOR-BACKED FINITE GROUND CPW AND A MICROSTRIP LINE.

This article describes a transition between a conductor-backed coplanar waveguide (CPW) and a microstrip line, which provides a very low loss alternative to a standard microstrip-to-coplanar line transition at higher frequencies. This simple topology is easy to incorporate in a monolithic circuit. The introduction of slots, along with the elimination of parasitic parallel plate modes and parasitic losses, are the main features of this transition. This MIC transition is designed for a center frequency of 20.5 GHz. The simulated and measured results of the transition, along with the design procedure, are detailed in the article.
