ABSTRACT:
The invention relates to a method and a base station of a radio system implementing the method and to an antenna array of the base station which enable both antenna diversity and beam forming using the same antenna array. In the solution described the antenna array comprises, in addition to a linear part configured for beam forming, a non-linear part which is used for forming diversity. Furthermore, the non-linear part enlarges the aperture of the antenna array, thus improving the quality of beam forming.
