Simple and Broadband Transition Between Rectangular Waveguide and Groove Gap Waveguide for MM-Wave Applications

摘要

A vertical wide band transition between a standard WR-15 rectangular waveguide (RW) and groove gap waveguide (GGW) in the V-band is presented. A simple step is applied to achieve a good impedance matching in transition between the RW and the GGW. A back-to-back transition is designed and fabricated to verify the simulation results. The measured results of the fabricated prototype show the insertion loss of less than 0.2 dB and the input reflection coefficient better than -16 dB over almost the whole V-band (50-75 GHz).
