A dual polarised edge coupled patch antenna element includes a patch radiator (1) and a ground plane (6), the ground plane being disposed in a substantially parallel relationship with the patch radiator (1). A first feed track (2) is connected at a first feed position on a first edge of the patch radiator and a second feed track (3) is connected at a second feed position on a second edge of the patch radiator, the second edge being at a right angle to the first edge. The first feed position is offset from the centre of the first edge and the second feed position is offset from the centre of the second edge, and the first feed position and the second feed position are each offset in a respective direction away from a corner between the first side and the second side.
