ABSTRACT:
The invention provides a multiple beam antenna and a method of fabricating such an antenna. The multiple beam antenna comprises: a flexible substrate having a conductive layer; a plurality of directional antennas; and a plurality of electrical connections being routed from each of the plurality of directional antennas to at least one area of the substrate. The plurality of directional antennas and the plurality of electrical connections are formed in the conductive layer, and the flexible substrate is shaped so that the plurality of directional antennas point in prescribed directions. This provides a low cost, high functionality multiple beam antenna. The multiple beam antenna can be shaped such that the directional antennas cover a full 360° or alternatively cover any range of other angles, (e.g. 270° or 180°).
