Patent ID: 11831084

Abstract:
A dual-polarized antenna, an antenna array, and a communications device are disclosed. The dual-polarized antenna includes a base board, a horizontally polarized antenna, and a vertically polarized antenna. The substrate includes a first substrate and a plurality of second substrates stacked on the first substrate. The horizontally polarized antenna includes a first radiating element disposed on the first substrate, and a first feeding unit that feeds the first radiating element. The vertically polarized unit includes a second radiating element and a second feeding unit that feeds the second radiating element. The second radiating element includes a first metal patch disposed on each second substrate. In the foregoing technical solution, the base board formed by the stacked substrates is used as a support part, so that the horizontally polarized antenna and the vertically polarized antenna are disposed on the base board, thereby reducing space occupied by the dual-polarized antenna.
