<p>The invention relates to a method of operating a transmitter (100) of a radio communications system, wherein a process of horizontal beam forming of an antenna characteristic of an antenna system (110) of the transmitter (100) is performed by applying (300) predetermined sets of weight factors (w_1_1,.., w_8_4) to signals associated with different antenna elements ( 110_1_1,.., 110_8_4) of said antenna system (110) for controlling the antenna characteristic in a horizontal direction, wherein at least one of said weight factors (w1l_1,.., w_8_4 ) is modified (310) so as to control said antenna characteristic in a vertical direction.</p> |
