The patch (32) comprises a first edge (F) connected electrically to the ground plane (8) and a further edge (G) arranged substantially parallel to the first edge (F) and a longer length than the first edge (F). In one embodiment a plurality, preferably four, patches (32) extend radially about a common point. <IMAGE>
