1. An antenna array, comprising:
a plurality of first antenna elements operating at least in a first frequency band and a second frequency band, wherein any frequency in the second frequency band is higher than any frequency in the first frequency band, wherein the plurality of first antenna elements are linearly arranged at intervals, and wherein a first center distance between every two adjacent first antenna elements is within a preset size range such that a gain of the antenna array in the first frequency band is greater than or equal to a target value, and wherein the preset size range is greater than or equal to 0.45 times a first wavelength corresponding to the first frequency band and less than or equal to 0.8 times the first wavelength; and
at least one second antenna element operating at least in a third frequency band, wherein the third frequency band at least partially overlaps the second frequency band, wherein the at least one second antenna element comprises a plurality of second antenna elements disposed between every two adjacent first antenna elements, and wherein a third center distance between every two adjacent second antenna elements is equal to a second center distance between each of the first antenna elements and each of the second antenna elements that are adjacent.
