1. An antenna array structure comprising:
a plurality of first antenna elements for transmitting and/or receiving a signal at a first frequency and a plurality of second antenna elements for transmitting and/or receiving a signal at a second frequency different from the first frequency,
wherein the plurality of first antenna elements are disposed in a first layer, and aligned, as viewed from a point above the antenna array structure, to a line extending in a first direction and the plurality of second antenna elements are disposed in a second layer and aligned, as viewed from the point above the antenna array structure, to the line,
wherein a first distance between two adjacent first antenna elements is different from a second distance between two adjacent second antenna elements,
wherein in a direction orthogonal to a major surface of a said first antenna element, a centrally located one of the first antenna elements overlaps a centrally located one of the second antenna elements, and
wherein a number of the plurality of first antenna elements equals a number of the plurality of second antenna elements.
