Abstract
A system for providing independent or co-spatial antenna patterns for independent inputs from a basestation comprises a phased-array antenna having a plurality of antenna columns radiating generally redundant antenna beam patterns. The array employs a feed network for feeding the antenna elements of the array. The feed network receives a plurality of independent inputs. Each of the inputs is split to feed specific ones of the antenna elements and to be combined and correspondingly weighted for output to a shared plurality of the antenna elements of the array. In one embodiment this combining and weighting is carried out by at least one hybrid matrix combiner. The weighting may include adjusting amplitudes and phases of the outputs by the combiner.
