1. An antenna array comprising:

  • a ground plane layer;

    a first set of antenna elements arranged on the ground plane layer and being configured to provide operation of the antenna array in at least three frequency bands respectively corresponding to three cellular frequency bands;

    a second set of antenna elements arranged on the ground layer and being configured to provide operation of the antenna array in two of the three frequency bands;

    the first set of antenna elements and the second set of antenna elements are substantially arranged along a longitudinal direction of the antenna array; and

    the first set of antenna elements and the second set of antenna elements are arranged on alternating positions along the longitudinal direction,wherein a ratio of a spacing between antenna elements of the first set to a wavelength of a first frequency band of the three frequency bands is substantially half of a ratio of a spacing between antenna elements of the second set to a wavelength of a second frequency band of the three frequency bands.
