Abstract

The present disclosure relates to a mmWave multi-beam transmitter comprising: - an antenna array; - a plurality of beam supply paths (Path 1, Path 2, Path 3, Path 4) each configured to supply a corresponding beam; - a multi-beam lattice-based selection matrix configured to simultaneously couple two or more of the beam supply paths to a plurality of antennas of the antenna array.
