The proposed waveguide-to-CPW transition is uniplanar, in line with the waveguide, and without air-bridge. Composed of a finline taper and a circular phase-shifter, it presents in simulation an insertion loss and a return loss better than 0.63 and 16.8 dB between 27 and 31 GHz. Measurements of the back-to-back structure are presented. (c) 2007 Wiley Periodicals, Inc.
