Abstract (en)

An adaptive antenna, comprising at least two modules (H1, H2) and at least one column of radiators (1) arranged on each of the antenna modules, characterised in that the modules (H1 and H2) are arranged edgeways next to each other and each of the modules has at least 8 radiators (1) along a vertical axis of the module (H1, H2). The resulting axes of antenna azimuths divide a 120° angular sector into equal sectors. A method consists in that the beam is modified and the modulated LTE signal is transmitted. CQI value is determined by means of UE, the CQI being transmitted in UL return channel to all elements of the antenna. By means of BBU, a path corresponding to the highest CQI which is optimal for the beam is chosen. The modulated LTE signal is multiplied by controlling vectors [K] and [L] of a multiplier system in an RRH module, and then it is transmitted to the power divider (2), and subsequently to the radiators (1) of one polarisation.
