A wideband high-gain and high-efficiency slot array antenna based on groove gap waveguide
Paper in proceeding, 2018
A groove gap waveguide based wideband high gain and high efficiency 8×8-element slot antenna array has been proposed for mmWave applications. A 16-way power divider based on groove gap waveguide is used as feeding network in this work. The antenna sub-array consists of four radiating slots that are backed by a groove gap cavity layer. The proposed antenna frequency band is from 48.8 GHz to 66.7 GHz and achieved maximum gain is about 27.4 dBi with a total efficiency of about 90 %.
