Title: Frequency and polarisation selective multibeam antenna
Filed: 2006-10-11
Abstract: An antenna comprises a substantially hemispherical dielectric lens 1, at least one antenna feed element 5, 6 and a selective reflective surface 2 on the planar face of the lens 1. The electromagnetic energy which passes through the selective reflective surface 2 is either absorbed or reflected by a further plane surface 3. The selective reflective surface 2 may relate to frequency and / or polarisation of the electromagnetic radiation signal being transmitted. The said dielectric lens 1 may have a constant, continuously radially varied or radially stepped refractive index. The antenna may be arranged to have a small radar cross section. Wedge or cylindrical shaped segments 4, from a sphere or cylinder dielectric body of a similar radius and formation as the said lens, may be used to form a stratified structure of selective reflective surfaces 2, 3. Single or cluster feed arrangements may be used with mechanical steering of the beam or beams by rotating the lens and reflective surface about a first symmetrical axis extending across the planar face of the lens 1 and by rotating the feed, lens and reflector about a second symmetrical axis extending through the lens, which is perpendicular to the first axis. Electronic scanning is also mentioned. Also disclosed is an antenna comprising a partially hemispherical lens with two plane faces with an angle of less than one hundred and eighty degrees between them, two spherical lens segments and two selective reflective surfaces which are arranged such that in operation one spherical lens segment combines with the partial hemispherical lens to provide a complete hemispherical lens with a first antenna focus and the other spherical segment combines with the lens to provide a second antenna focus. The antenna provides a cheap, compact arrangement for steering multi-beams possibly in array formations.
