Embodiments of the present invention relate to an antenna array. The antenna array comprises at least two subarrays. Antenna units in a same subarray are fed by using a same feed port. In the antenna array, adjacent two antenna units in each row and/or each column are respectively fed by using different feed ports of the at least two feed ports. In each subarray of the at least two subarrays, a distance between adjacent two antenna units in each row and/or each column is greater than or equal to a preset threshold. The antenna array in the embodiments of the present invention can generate multiple beams, significantly increase communication coverage in a scenario of a millimeter-wave narrow beam, and avoid a disadvantage that a conventional millimeter-wave multi-beam high-gain antenna has insufficient capability of angular coverage. Meanwhile, multiple subarrays having large unit intervals are overlapped with each other, to implement effective use of an array aperture and improve antenna coverage, so that at the same time when spatial coverage of a beam is increased, communication requirements of multiple users are met, a system beam is easy to control, a structure is simple, and implementation is easy. |
