This paper presents a wideband high efficiency slot antenna array based on ridge gap waveguide technology at 60 GHz for millimeter-wave applications. The antenna sub-array consists of four radiating slots that are excited by a cavity. Some tuning pins are placed inside the cavity to achieve wideband performance. A 4×4 slots array antenna is designed using 4-ways power divider. The proposed structure exhibits 30% impedance bandwidth (|S11| < -10 dB) covering form 50 GHz to 67.8 GHz. The gain up to 21.5 dBi is obtained with total efficiency more than 90%.

Nyckelord: 60 GHz applications , gap waveguide technology , wideband slot antenna array
