Patent ID: 8270375

Claim:
An apparatus of a multi-antenna telecommunication system, the apparatus comprising: an analogue radio frequency level beam forming unit comprising a plurality of correlated antenna elements configured to form at least two antenna beams, the plurality of correlated antenna elements comprising an average separation of more than half of a communication carrier wavelength, the analogue radio frequency level beam forming unit comprising at least one phase-shift module connected to at least two correlated antenna elements and configured to receive a beam-specific data stream and feed the beam-specific data stream to the at least two correlated antenna elements by using beam forming phases which implement a chosen antenna beam, the correlated antenna elements being arranged in at least one row or column, and the separation between outermost successive antenna elements being greater than separation between middle antenna elements; and a signal feeding unit connected to the beam forming unit and configured to feed beam-specific data streams to the beam forming unit, wherein the beam-specific data streams are allocated to one transceiver and wherein each beam-specific data stream comprises different data.
