Claim Text:
1. An antenna array comprising: a ground plane; a first set of radiating elements configured to operate at a first frequency band, wherein a plurality of radiating elements of the first set operate at only the first frequency band; a second set of radiating elements configured to operate at a second frequency band, wherein a plurality of radiating elements of the second set operate at only the second frequency band; a third set of radiating elements, wherein a plurality of radiating elements of the third set are configured to operate at the first frequency band and a third frequency band, the third frequency band not overlapping with the first frequency band and the second frequency band; the plurality of radiating elements of the first set and the plurality of radiating elements of the third set are arranged along a first substantially vertical direction of the ground plane; each radiating element of the plurality of radiating elements of the first set is adjacent to a radiating element of the third set; at least one pair of adjacent radiating elements of the second set are displaced off the first substantially vertical direction of the ground plane; a vertical spacing between the at least one pair of adjacent radiating elements of the second set is different than a vertical spacing between the radiating elements arranged along the first substantially vertical direction of the ground plane; a combination of the plurality of radiating elements of the first set and the plurality of radiating elements of the third set provides operation of the antenna array at the first frequency band; a combination of all radiating elements of the third set provides operation of the antenna array at the third frequency band; and a combination of the plurality of radiating elements of the second set provides operation of the antenna array at the second frequency band.
