Antenneneinrichtung für Basisstation

摘要

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 splitting (58; Figs. 14b,14c) the transmission output of a given transceiver into two signals prior to transmission power amplification and transmitting said signals in two adjacent narrow overlapping beams.
