Design and Fabrication of a High Gain 60-GHz Cavity-backed Slot Antenna Array fed by Inverted Microstrip Gap Waveguide
Artikel i vetenskaplig tidskrift, 2017

This paper deals with the design of a 16x16 slot array antenna fed by inverted microstrip gap waveguide (IMGW). The whole structure designed in this work consists of radiating slots, a groove gap cavity layer, a distribution feeding network and a transition from standard WR-15 waveguide to the IMGW. Firstly, a 2x2 cavity-backed slot sub-array is designed with periodic boundary condition to achieve good performances of radiation pattern and directivity. Then a complete IMGW feeding network with a transition from WR-15 rectangular waveguide to the IMGW has been realized to excite the radiating slots. The complete antenna array is designed at 60-GHz frequency band and fabricated using Electrical Discharging Machining (EDM)technology. The measurements show that the antenna has a 16.95% bandwidth covering 54-64 GHz frequency range. The measured gain of the antenna is more than 28 dBi with the efficiency higher than 40% covering 54-64 GHz frequency range.
