Abstract

The proposed cavity-backed slot antenna is comprised of baffles, reflectors and thick ground plane. The baffles and reflectors are used to increase an antenna gain, thus reducing the coupling among slots on a thick ground plane. The height of the baffle and reflector were altered and the characteristics of corresponding $2{\times}2$ cavity-backed slot array antennas were measured separately. Themeasured antenna gains were above 15dBi, at f=42GHz and a wide impedance bandwidth over 27% at a center frequency of 42GHz.
