ABSTRACT:
A communications antenna assembly is disclosed, suitable for use in fixed antenna multiple access systems, such as fixed wireless access schemes and satellite communication systems. Such systems have independent base station transmitters which, in the case of fixed wireless access schemes, may be subject to over capacity and/or obstructions between the subscriber and the base station and, in the case of non-geostationary satellite communication systems continuously move. The antenna is operable to communicate with at least one of two communication stations at each of two directions from the antenna assembly, said assembly comprising: a beamformer connected to the antenna and arranged to allow the antenna to provide at least two antenna beams, one substantially in each of the communication station directions are provided substantially simultaneously, such that in use the antenna assembly can communicate with the two communication stations. A corresponding system and method of use is also described.
