摘要： An antenna system comprising a base station, a plurality of antenna elements combined to an antenna, whereas the plurality of antenna elements of one antenna is connected to an antenna element mapper each connected to the base station via an antenna port. The inventions relates also to a method for providing antenna elements of an antenna system with antenna signals whereas the antenna signal is distributed to multiple antenna elements and weighted with antenna element specific parameters. The object of the invention is to provide a configuration that can individually control more antenna elements than the number of antenna ports. This is solved by arranging the antenna elements in an antenna element array wherein all antenna elements are controlled individually; storing antenna port specific beam forming vectors in the antenna array; and every antenna element of the antenna element array is individually controlled by an antenna element specific vector element of the beam forming vectors.
