One example antenna apparatus includes S groups of antenna bays, S groups of phase-shift feeding networks, and S beamforming networks. An igroup of antenna bays include Nbays, an igroup of phase-shift feeding networks include Nphase-shift feeding networks, and the Nbays are connected to the Nphase-shift feeding networks. In a first state, an ibeamforming network is configured to form nbeams corresponding to the Nbays, where Nfirst ports corresponding to the beamforming network are connected to the Nphase-shift feeding networks, nsecond ports corresponding to the beamforming network are connected to nantenna ports, and nis less than N. In a second state, an ibeamforming network is configured to form Nbeams corresponding to the Nbays, where Nfirst ports corresponding to the beamforming network are connected to the Nphase-shift feeding networks, and Nsecond ports corresponding to the beamforming network are connected to Nantenna ports.

Embodiments of the present application provide an antenna adjustment method, an antenna, and a base station control center, where the antenna includes: a detection unit, configured to detect a current orientation parameter of the antenna; an obtaining unit, configured to obtain remote electrical tilt data of multiple element arrays in the antenna that are corresponding to a target frequency band, where the remote electrical tilt data is determined according to a difference between a target orientation parameter of a beam of the multiple element arrays and the current orientation parameter; and an adjustment unit, configured to adjust an orientation of the beam of the multiple element arrays according to the remote electrical tilt data. According to the embodiments of the present application, multiple element arrays in the antenna that are corresponding to each frequency band can be separately adjusted, thereby improving antenna performance.
