Abstract: An antenna array includes a plurality of first antenna elements and second antenna element(s). The first antenna elements operate at least in a first frequency band and a second frequency band, and any frequency in the second frequency band is higher than any frequency in the first frequency band. The second antenna element(s) operate at least in a third frequency band, and the third frequency band at least partially overlaps the second frequency band. The first antenna elements are arranged at intervals, and the second antenna element(s) is/are disposed between at least two adjacent first antenna elements. A center distance between every two adjacent first antenna elements is within a preset size range, so that a gain of the antenna array in the first frequency band is greater than or equal to a target value.
