Definitions

  • the present invention relates to a system for receiving orthogonal polarization microwave signals essentially comprising, following a parabolic reflector, a reception horn, a bandpass filter, possibly a polarizer, as well as a mode separator and a housing containing electronic amplification and frequency conversion circuits.
  • This system can be used in particular for the reception, whether individual, collective or community, of circularly polarized television signals transmitted in the frequency band 11.7 to 12.5 gigahertz by geostationary satellites, in successive channels which partially overlap and between which discrimination can only be made by polarization (left circular for one of the channels, right circular for the other).
  • the realization of such systems currently involves the precise assembly of the essential organs mentioned above, an operation which is industrially costly.
  • the object of the present invention is to propose a system as defined above, but of a considerably simplified and therefore considerably less expensive embodiment, which allows mass production.
  • the invention relates to a system for receiving microwave signals with linear orthogonal polarizations essentially comprising, following a parabolic reflector, a reception horn, a bandpass filter, a mode separator and a box containing electronic amplification and frequency conversion circuits, characterized in that the horn and the filter are produced as a waveguide and are, with the mode separator and the housing, carried by the same support consisting of two half-shells symmetrical with respect to their longitudinal assembly plane and capable of being manufactured by a common industrial process such as, in particular, molding or injection of metal or plastic material subsequently metallized.
  • the system is designed to receive signals with circular orthogonal polarizations, it further comprises, before the mode separator, a polarizer also produced as a waveguide. In either case, the advantage of the system is obvious, namely its simplicity of manufacture and assembly.
  • connection between the waveguide part and the circuits contained in the housing can then, according to the invention, be ensured either by a mode separator in conventional waveguide with rectangular cross section subdivided or not into two separate guides depending on whether or not we want to receive two signals of different polarization simultaneously, either by the presence in the waveguide part of a mode separator consisting of at least one coaxial element penetrating inside this guide part wave, or finally by the presence of a mode separator consisting of at least one element for receiving microwave signals, produced in a planar structure according to the printed circuit technique associated with a dielectric support and arranged transversely to the longitudinal axis of the waveguide part.
  • the system according to the present invention relates to the reception of microwave signals with circular polarizations and comprises for this purpose, following a parabolic reflector not shown, successively a receiving horn 2, kept at the focus of the reflector, a bandpass filter 3, a polarizer 4 with a dielectric or metallic blade, a mode separator 5, as well as a box 6 containing the electronic amplification and conversion circuits frequency required as an interface between the actual reception system and the final television receiver.
  • the polarizer 4 is not provided.
  • These elements 2 to 6 are, according to the invention, produced as a waveguide (here square or cylindrical) and carried by the same support, which is a set of two half-shells 10 and 11 symmetrical with respect to the longitudinal plane according to which they can be assembled one on the other (using for example fixing screws).
  • These two half-shells 10 and 11, of simple structure can therefore be produced by the implementation of a common industrial process, for example by molding, or by injection of metal, or by injection of plastic material subsequently metallized.
  • the half-shells are symmetrical, but not identical and therefore cannot be produced with the same mold.
  • the connection between the waveguide part and the circuits contained in the housing 6 is ensured by the subdivision of the mode separator 5 into two waveguides 5a and 5b of orthogonal rectangular straight sections, these two guides being coupled respectively to two plates 12 and 13 for supporting these circuits placed perpendicularly to each other in the housing and can be produced in printed circuit.
  • Each plate 12 or 13 carries, for the microwave signals of corresponding circular polarization (left or right), the necessary amplification and frequency conversion circuits.
  • cables-22 and 23 down to the signal processing unit and the television receiver.
  • the housing 6 is used to carry the plates 12 and 13, but also to guarantee the mechanical protection and the tightness of the assembly thus produced.
  • connection between the waveguide part and the circuits contained in the housing 6 is provided by the presence, in a cross section (seen in the plane bb of FIG. 2) of the system, of an element 15 for receiving microwave signals, produced in planar structure according to the technique of the printed circuit associated with a dielectric support (such elements are already known and will not be described here).
  • This element is then coupled, via two coaxial lines 16 and 17 carrying respectively the left and right circular polarization signals, to the two plates 12 and 13 (at the other end of these plates the down cables 22 and 23 are always provided).
  • the half-shells are not only symmetrical but identical and can therefore be produced with the same mold, which further reduces the costs of industrial manufacture.
  • Figure 2 corresponds to the case where the element 15 is put in place by pressing against a shoulder 18 located inside the half-shells 10 and 11, then screwing, and
  • Figure 3 in the case where these half-shells are made in two parts 10a, 10b and 11a, 11b assembled by screwing along the plane AA so as to enclose the element 15.
  • the mode separator may consist of only one waveguide, with rectangular cross section, coupled to a single support plate for the amplification and conversion circuits.
  • the connection between the waveguide part and these circuits can also, in another embodiment, be ensured by the presence, in this waveguide part, of a (reception of a single signal) or two (simultaneous reception of two signals of different polarization) coaxial elements penetrating into said part sufficient to operate the sampling of the signals; the coaxial element or elements thus provided are coupled by their other end to the circuits of the housing 6.
  • the bandpass filter can, instead of being provided after the reception horn, be placed only between the guide (s) wave of the mode separator and the corresponding plate or plates for supporting the circuits of the housing 6.
  • each half-shell can itself be produced in two separate parts which can be assembled, in particular in the case where the mode separator comprises a receiving element in planar structure, and where the assembly plane of the distinct parts of each half-shell then coincides with the plane of installation of this receiving element.
  • the two half-shells 10 and 11 are, preferably, provided with members for fixing the mechanical link arms with the parabolic reflector, as well as with a radome placed on the receiving horn 2 to complete the weatherproofing of the system.
