Abstract
An antenna is provided, in combination with an associated switch array, the antenna comprising a number of antenna elements mounted above a ground plane for providing coverage over a predetermined range of angles in azimuth using a number of beams. Each of the antenna elements is connected to a switch in the switch array and the switch array is operable to connect selected pairs of the antenna elements to a signal path to thereby generate each of the different beams, at the same time connecting unselected antenna elements to ground.
