Millimeter wave high gain antenna based on gap waveguide technology

Paper i proceeding, 2018

© 2017 IEEE. In this work, we present wideband gap waveguide planar array antenna for millimeter wave point to point backhauling systems. The proposed antenna is designed using ridge gap waveguide technology and the design is based on the cavity-backed slots as the core radiating elements. There exists a coupling slot in the cavity layer which allows the excitation of the radiating slot elements using ridge gap waveguide feeding section. The designed antennas have 8×8 or 16×16 radiating slot elements and the antenna operate over 15% relative bandwidth from 56-67GHz frequency range with -11 dB reflection coefficient. The measured gain for the slot arrays are within the range from 27 dBi-33dBi at the center of the band.
