Wide Scanning Gap Waveguide Slot Array Antenna for 100 GHz Applications Using decoupling Technique
Licentiatavhandling, 2024
This thesis presents our first beam scanning array design at 100GHz, a high-efficiency one-dimensional wide-scanning solution based on GWG slot array antenna. Utilizing a novel decoupling technique, for the first time, the all-metal slot array achieves ±60° wide-angle scanning at E-plane, with 3-dB scan loss and >91% total efficiency. Subsequently, various slot array decoupling techniques are also compared and studied to analyze their unique properties and suitable application scenarios.
The proposed slot antenna will be used to manufacture a 100 GHz phased array demonstrator, and it will also serve as the basis for future two-dimensional scanning antenna designs.
