A Broadband Millimeter-Wave Rectangular-to-Coplanar Waveguide Transition.

The article presents an error analysis and appropriate test method on the broadband transition of rectangular waveguide (RW) to coplanar waveguide (CPW) at U-Band, which uses a transverse E-plane probe to get a wide bandwidth. Topics include the back-to-back (BTB) transition design, simulation results and findings of the transition, and key parameters of the transition.
