Abstract
A cellular beamforming base station antenna is provided having a reflector, a plurality of signal ports located at the bottom of said reflector, a calibration circuit, a plurality of beamformers, coupled to the signal ports, and a plurality of radiating elements, coupled to the beamformers. The plurality of radiating elements are arranged into a plurality of vertically aligned columns disposed across a width of the reflector, the plurality of radiating elements are each also positioned in one of a plurality of horizontally aligned rows along the length of the reflector. Elements in one of the plurality of rows of elements are connected to at least a first of the plurality of beamformers. Elements in another of the plurality of rows of elements are connected to a second of the plurality of beamformers. Outputs of the first and second beamformers are connected to the calibration circuit which is connected to different ports located on a bottom of the reflector.
