Abstract: This application provides an antenna apparatus. The antenna apparatus includes a signal processing module and an antenna. The signal processing module is configured to perform feeding for a signal received or to be sent by the antenna. The antenna is configured to send or receive the signal. The signal processing module is separately connected to the antenna and a radio frequency unit in a pluggable manner. In addition, the signal processing module includes at least a feeding network. By using the antenna apparatus provided in this application, signal processing components are integrated into a pluggable module. In this way, the antenna apparatus can use different signal processing modules as required by different scenarios.

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.

Abstract: Embodiments of this application disclose an antenna calibration method and system. The system includes a baseband processing unit, a remote radio unit, an antenna array, and a coupled antenna. The antenna array sends a radio frequency calibration signal sent by the baseband processing unit, or receive the radio frequency calibration signal. The remote radio unit provides a plurality of transmission channels, where the plurality of transmission channels correspond to a plurality of transmission ports. The coupled antenna receives the radio frequency calibration signal sent by the baseband processing unit, and transmit a coupled signal corresponding to the radio frequency calibration signal to the baseband processing unit, or send the radio frequency calibration signal. The baseband processing unit calibrates, based on a difference between the radio frequency calibration signal and the coupled signal, a plurality of to-be-sent baseband signals corresponding to the plurality of transmission channels.
