Abstract: One example antenna apparatus includes S groups of antenna bays, S groups of phase-shift feeding networks, and S beamforming networks. An ith group of antenna bays include Ni bays, an ith group of phase-shift feeding networks include Ni phase-shift feeding networks, and the Ni bays are connected to the Ni phase-shift feeding networks. In a first state, an ith beamforming network is configured to form ni beams corresponding to the Ni bays, where Ni first ports corresponding to the beamforming network are connected to the Ni phase-shift feeding networks, ni second ports corresponding to the beamforming network are connected to ni antenna ports, and ni is less than Ni. In a second state, an ith beamforming network is configured to form Ni beams corresponding to the Ni bays, where Ni first ports corresponding to the beamforming network are connected to the Ni phase-shift feeding networks, and Ni second ports corresponding to the beamforming network are connected to Ni antenna ports.
