A High Gain Ridge Gap Waveguide Fed Slot Antenna Array for 60 GHz Applications

چکیده مقاله

In this paper, a high gain high efficiency 16×16- element slot antenna array is presented for 60 GHz applications. The antenna is designed based on gap waveguide technology. A corporate feed network is realized by a texture of pins and a guiding ridge in a bottom plate. The simulated results show about 16% of reflection coefficient bandwidth (|S11| < -10 dB) covering 57-67 GHz frequency range. Also, the gain of the antenna is more than 32.5 dBi with an efficiency higher than 85% over the desired frequency band.
