Definitions

  • the invention relates to an antenna for satellite reception with a parabolic mirror surface and a receiver arranged in its focal point above a flat base surface.
  • Such antennas are known. It is planned to broadcast television programs via geostationary satellites. Receiving antennas are required in the customer's property for reception. There is a desire to build such antennas as compact as possible so as not to limit the installation options.
  • the object of the invention is to propose an antenna of the type mentioned at the beginning, the overall height of which is reduced compared to conventional parabolic antennas.
  • the above object is achieved in the case of an antenna of the type mentioned at the outset in that the mirror surface consists of a plurality of concentric mirror rings, the focal points of which are essentially at the receiver, that the inner edge of each mirror ring is closer to the base surface than the outer edge of the next inner mirror ring and that a transition surface runs between these edges.
  • the overall height of the mirror surface is thus considerably reduced compared to a parabolic.
  • the necessary distance of the receiver from the center of the mirror surface is also reduced.
  • the shape of the mirror rings is in each case part of a parabolic.
  • a carrier body holding the mirror rings can be simple.
  • the carrier body is formed from a solid plastic body.
  • these are arranged so that the focal point lies in the line of alignment of the transition surface.
  • the antenna shown in the figure has a receiver 2 arranged over a base area 1.
  • the base surface 1 is the underside of a carrier body 3, which can be formed, for example, by a solid plastic body.
  • a carrier body 3 which can be formed, for example, by a solid plastic body.
  • mirror rings 4, 5, 6 are provided, which can be metal mirrors or metallized plastic on the mirror side.
  • the shape of the mirror rings 4, 5 and 6 correspond to rings of different parabolas. Your focus is on the recipient 2.
  • the mirror rings 4, 5 and 6 are arranged such that their inner edge 7 is closer to the base surface 1 than the outer edge 8 of the next inner mirror ring. Between the edges 7 and 8 extend transition surfaces 9, which are non-reflective. The transition surfaces 9 are aligned so that their alignment line passes through the receiver 2, so that the transition surfaces 9, seen from the receiver 2, do not form any shading in the region of the inner edges 7 of the mirror rings 4 to 6.
  • the outer edges 8 are then offset from one another towards the base surface 1, as shown in the figure.
  • the inner edges 7 can lie at the same height above the base surface 1 in order to utilize the available height B.
  • the overall height B is significantly smaller than the overall height C of a parabolic mirror of the same diameter would be. Such a parabolic mirror shape is indicated by dash-dotted lines in the figure. Obviously, the overall height has been reduced from B - C.
