Abstract

The invention relates to an antenna array in a telecommunication system, wherein a number (1, 3, 6, 12) of rectangular panels consisting of 8 columns with 4 vertically spaced antenna elements are combined together to build up the antenna array, the radiation pattern of which is adaptively steerable.
