<p>In order to make it possible to increase the traffic capacity in mobile radio networks and to reduce the transmitted power, it is necessary to provide base stations for producing directional beams. The invention is thus based on the object of providing a mobile radio system and an antenna assembly which allow an area to be illuminated to be subdivided into a plurality of area segments, using a conventional transceiver, without any major circuitry complexity, and thus economically. The mobile radio system which is provided has at least one base station (10) which has a plurality of first transmitting/receiving devices (401-404), and an antenna device (23) associated with it. Furthermore, an RF beamformer (22) is provided, whose first ports (1 to 4) are associated with the first transmitting/receiving devices (401 to 404) and whose second ports are associated with the antenna device (23). The RF beamformer (22) interacts with the antenna device (23) in such a way that an individual antenna directional characteristic is permanently assigned to each first port (1 to 4). <IMAGE></p> |
