Abstract
In one embodiment, the present invention is a dual-polarized antenna array constructed from first and second instances of a planar antenna that are co-located and orthogonal to one another. The planar antenna comprises three conducting elements and a transmission line. The first conducting element comprises a straight segment and two arms of equal length. The proximal ends of the two arms are attached to opposite ends of the straight segment. The arms extend away from the second and third conducting elements and towards one another. The second and third conducting elements are separated by a gap and together form a mirror image of the first conducting element. The transmission line has first and second conductors that are coupled to the second and third conducting elements, respectively. In another embodiment, the present invention is a tri-polarized antenna array constructed from three orthogonal co-located instances of the planar antenna.
