A multibeam phased lens array has been proposed, in which multiple multibeam lens antennas are arranged and electronic beam scanning is achieved by combining multibeam switching with phase-difference feeding between lenses. However, when a beam is formed in the crossover direction, grating lobes increase. In this study, grating lobes are reduced by in-phase combining of adjacent beams in the crossover direction.
