Definitions

  • the invention relates to a device for covering the aperture of an antenna a parabolic reflector, an exciter and a cover made of rigid material has, whose outer diameter corresponds to the diameter of the reflector and on its side facing away from the reflector is curved outwards (DE 44 36 596 A1).
  • Covers are mainly used on antennas to protect them Weather conditions attached. By depositing dirt, moisture and ice the transmission properties of the antennas can be adversely affected. Through ice can also result in a significant weight load on the antennas mechanical damage can result.
  • FR 2 669 469 A describes an antenna with a parabolic reflector, in which the Protection of exciter and converter attached to the reflector a one-piece, overall arched Plastic cover is connected to the reflector.
  • the invention has for its object the device described above with respect To simplify construction and assembly.
  • the cover from one with the Shielding ring connected to the reflector and from a sealing ring which closes the same at the free end is made of plastic cover, which is designed as a flat cone and its Wall with a plane perpendicular to the axis of the shielding ring Includes angles between 4 ° and 6 °.
  • Such a device for protecting antennas is simple in construction and easy to use assemble. It then consists of only one part, namely the cover when the shielding ring is integrally connected to the reflector.
  • the lid designed as a flat cone, does not have one disturbing influence on the electromagnetic properties of the antenna. This is especially true for the radiation pattern of the antenna, but not because of the flat cover, at least is not significantly affected. Due to its outward sloping course it is also ensured that dirt, moisture and ice are not present in substantial quantities can attach to the antenna.
  • the Cassegrain version of the antenna could also be equipped with a subreflector be equipped.
  • An approximately cylindrical shielding ring 4 is attached to the reflector 1, the outer diameter of which corresponds to the diameter of the reflector 1.
  • the shielding ring 4 is particularly useful for antennas with smaller dimensions connected in one piece with the reflector 1. So he will be at the Manufacture of the reflector 1 molded onto the same. Basically, the shield ring 4 but also be a separate part. It is then connected to the reflector 1. Of the Shielding ring 4 is on its side facing away from the reflector 1 by a plastic existing cover 5 closed. The lid 5 is curved outwards. Its more precise structure 2 shows:
  • the cover 5 is designed as a flat cone. Its straight wall runs towards a plane, which is arranged perpendicular to the axis A of the shielding ring 4, under a Angle ⁇ between 4 ° and 6 °. For example, it is 5 °.
  • the wall thickness of the Cover 5 is dimensioned depending on the frequency. It is in the range from 10 to 60 GHz for example between 8.5 mm and 1.5 mm.
  • the cover 5 is produced by injection molding. He has one circumferential cylindrical edge 6 for its attachment to the shielding ring 4. For this purpose for example screws are used.
  • a dielectric is preferably used as the material high quality plastic used. This is, for example, an acrylonitrile-styrene-acrylic ester polymer (ASA).
