ABSTRACT:
A method of forming directional antenna beams, comprising: directing at least two antenna beam signals by means of a beam formation matrix and pre-phasing pre-determined antenna beam signals formed with an antenna array in such a way that the signal of at least one antenna beam has a different phase compared with the signals of other antenna beams. The pre-phasing is implemented with a pre-phasing element, which comprises phasing coefficients in digital implementation. The pre-phasing element is implemented in such a way, for example, that the power of the sum signal of the antenna elements is evenly distributed to the different antenna elements in a pre-determined variation range.
