Abstract
A beamforming network for use with a plurality of antenna elements arranged in a planar array of linear sub-arrays includes first and second sets of beamforming sub-networks. Each beamforming sub-network in the first set of beamforming sub-networks is associated with a respective one of the linear sub-arrays and is adapted to generate, via the associated linear sub-array, fan beams along respective beam directions in a first set of beam directions. Each beamforming sub-network in the second set of beamforming sub-networks is associated with a respective one of the beam directions in the first set of beam directions. For each beamforming sub-network in the second set of beamforming sub-networks, each of the output port is coupled to an input port of a respective beamforming sub-network in the first set of beamforming sub-networks that corresponds to the associated beam direction. The application further relates to a multibeam antenna comprising such beamforming network.
