A novel twist between Gap Waveguides for compact slot-array antennas

Abstract:

A compact twist connecting a Ridge-Gap Waveguide and a Groove-Gap Waveguide at 38 GHz is presented. This twist is intended for feeding an array antenna. Simulations show a return loss better than 20 dB between 37.3 GHz and 38.3 GHz. The insertion loss is below 0.4 dB within the same frequency band. This bandwidth may be enough for many applications.
