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 operating (FIG. 12a, FIG. 12b) two or more non-collocated narrow beamwidth antenna arrays to form jointly a broad beamwidth antenna radiation pattern wherein the time averaged antenna pattern is substantially null free.
