<p>An antenna capable of creating a steerable circularly polarized directive beam is disclosed. It includes a plurality of circularly polarized radiator elements adapted to receive and emit electro-magnetic signals; a conductive base plane; and mounting means for each radiator element relative to the base plane. The antenna may include moving means adapted to rotate at least part of the radiator elements independently and angularly to obtain a phase shift relative to an unrotated radiator element or a differently rotated radiator element and the mounting means may be adapted to allow independent rotation of each radiation element relative to the plane.</p> |
