Definitions

  • the present invention relates to a radiating element or receiver of microwave signals with left and right circular polarizations, as well as a planar antenna comprising an array of such juxtaposed elements.
  • This invention finds its application in the field of reception of 12 gigahertz television signals retransmitted by means of satellites.
  • a previous French patent application filed by the applicant company on May 4, 1981 under No. 81 08 780 describes a planar microwave antenna composed of receiver elements and comprising on the one hand two superimposed planar dielectric layers each comprising on their outer face a conductive ground plane with non-conductive recesses located two by two opposite one another and revealing the dielectric layer, on the other hand two distinct plane networks of .plate lines located in the median plane between the two layers plane dielectrics, and, optionally, pairs of dipoles arranged in a cross in the same median plane as these networks opposite the non-conductive recesses.
  • the two networks of triplate lines intended to ensure, whether the dipoles are provided or not, the coupling of each receiving element with the antenna output are arranged in the same single plane, which, taking into account the density of the lines d feeding as soon as the number of receiving elements is high enough, makes their realization quite delicate.
  • the object of the invention is to provide a more economical antenna.
  • the invention relates to a receiver element for microwave signals with left and right circular polarization (or, according to the principle of reciprocity of antennas, a radiating element for such signals produced in a similar manner) which successively comprises a first insulating layer in which is provided a mini-horn of square section and metallized interior surface, a first supply network for the reception of the signals whose polarization is of a first type, a second insulating layer in which is provided a mini-guide square section wave on the side of the first network and rectangular section at the other end, and of metallized inner surface, a second supply network for the reception of signals whose polarization is perpendicular to that of the signals received by the first network, and a third insulating layer in which a metallized interior surface mini-waveguide, of the same rectangular section on the side of the second network and short-circuited, so that its length is less than the thickness of this third layer.
  • the antenna also relates to an antenna comprising a network of such elements, juxtaposed as close as possible.
  • the antenna thus proposed, while retaining good performance and ensuring satisfactory insulation between receiving elements, is relatively simple to produce, since the supply networks are now distributed on two distinct levels, and therefore have less complexity than when implemented in a single plan.
  • FIG. 1 in perspective, an example of planar microwave antenna comprising a whole array of receiving elements in accordance with the invention
  • FIG. 2 a section showing the arrangement of the supply networks
  • FIGS. 3a and 3b two diagrams showing the installation of the depolarization device for obtaining signals with right circular polarizations and left.
  • Each of these two supply networks consists of a series of successive stages of combination of the signals received by each receiver element, according to a conventional geometric arrangement such as for example that shown in FIG. 1 of the United States patent. 'America N ° 3 587 110 issued on June 22, 1971 to the nor of the transferee RCA Corporation. Recesses can be provided (see FIG. 2) in the layers adjacent to the plane of the supply networks so as to allow, in a balanced arrangement such as that of FIG. 4 of this same cited patent, the progression of the lines of these networks from each of the individual receiver elements of the antenna to the single output connection of each of the two networks, passing through the successive combination stages.
  • a 3dB hybrid coupler is provided at the output of the two supply networks, the single output connection of one of these networks being connected to an input of the coupler and the single output connection of the other network to the other input, and the two outputs of this coupler supplying said signals with right or left circular polarization (see the diagram in FIG. 3a).
  • the present invention is not limited to the embodiment described and shown, from which variants can be proposed without thereby departing from the scope of the invention.
  • the right or left circular polarization signals can be obtained not with a 3dB hybrid coupler placed downstream of the antenna, at the output of the supply networks, but with a depolarizing device, of the type known to meanders for example, placed in front of the antenna as shown in the diagram in Figure 3b.
