Abstract :
A novel rectangular-waveguide-to-coplanar-waveguide transition is described. The transition uses a ridge in one of the broad walls of the waveguide and a nonradiating slot in the opposite wall to split and rotate the electromagnetic fields of the rectangular waveguide TE/sub 10/ mode into the coplanar waveguide (CPW) fields. This transition should permit the use of CPW-based circuits in the millimeter-wave frequency range and the development of microwave probes above 50 GHz for fast and inexpensive testing of the millimeter-wave circuits.<>
