An antenna diversity arrangement (200) comprises a plurality of antennas (204a, 204b) capable of forming a plurality of antenna beams. The amplitude and phase relationships between the signals driving each of the antennas (204a, 204b) are first determined for an arrangement where each antenna is replaced by a point source. The results of this analysis are then transformed by reference to the characteristics of the real antenna arrangement (200) to determine appropriate driving signals.The resultant antenna diversity arrangements (200) can have antennas (204a, 204b) located arbitrarily close to one another with near-zero correlation between any pair of the antenna beams, thereby providing a compact and effective arrangement.
