| Zusammenfassung: | A compound radio antenna 1 comprising a plurality of directional antenna elements a-f and provided with control circuitry 2,3,4 adapted selectively to enable one or more of the elements a-f in direct response to detected characteristics of received radio signals. The antenna 1 is able to make use of angular and/or polarisation diversity, and is able intelligently to steer from a substantially omni-directional mode of operation to a highly directional mode in response to the received radio signals, thereby helping to improve sensitivity and gain while reducing interference. |
