Abstract:
An array antenna comprising:(a) a first plurality of super elements, each of said first plurality of super elements comprising N radiating elements;(b) a second plurality of super elements, each of said second plurality of super elements comprising M radiating elements where M is not equal to N;(c) a beamforming circuit;(d) a circuit to selectively couple the M and N radiating elements of said first and second plurality of super elements to said beamforming circuit, such that in response to said circuit coupling each of the M and N radiating elements of said first and second plurality of super elements to said beamforming circuit, the antenna is provided having a first field of view and in response to said circuit coupling each of the N radiating elements to said beamforming circuit and isolating each of the M radiating elements from said beamforming, the antenna is provided having a second field of view which is different than the first field of view.
