An adaptive antenna array comprises a plurality of parallel spaced linear arrays. A first group of closely spaced linear arrays 230 has a distance between adjacent linear arrays of about 0.5 g . A second group 240 has a wider separation between adjacent linear arrays, in the range 1 - 10 g . The antenna elements of the linear arrays may be dipoles or flat plate elements. A reflector may be included. The array might also include a third group (502,504) of transmit linear arrays. The first group 230 provides a good sector coverage beam whilst the second 240 group provides good spatial diversity. The adaptive antenna array has application in cellular telecommunication base stations using the UTMS WCDMA standard.
