ABSTRACT:
An antenna for a base station comprising a plurality of antenna arrays (40; FIG. 6a) each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams formed by the arrays provide a coverage in azimuth wider than each array. Means are provided for selecting (72, 80, 82; FIG. 6b) for a given call more than one of the best received signals from the multiplicity of narrow overlapping beams and for combining the selected signals to form a single receive signal input for an r.f. transceiver for the given call.
