D-Band Slot Array Antenna Using Combined Ridge and Groove Gap Waveguide Feeding Network
Paper i proceeding, 2019

In this paper, the design of a cavity-backed slot array antenna based on combination of ridge and groove gap waveguide for D-band applications is investigated. The proposed subarray has 2×2 slots with impedance bandwidth of 20 % covering from 127 GHz to 155 GHz. A feeding network combining groove gap waveguide and ridge gap waveguide has been proposed also in this work. The feed network has been designed as a combination of ridge gap waveguide and E-plane groove gap waveguide to reduce the losses in the feed network of a large antenna array, thereby increasing the total efficiency of the array antenna.
