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 of beams formed by the arrays provide a coverage in azimuth wider than each array. Means are provided for recognizing unique identifier signals (70; FIG. 6b) incorporated in call signals passing through the antenna; and coherent detection means for discriminating between unwanted call signals and wanted call signals using said unique identifier signals.
