Definitions

  • the present invention relates to a waveguide antenna output for a planar antenna with an array of radiating elements or receivers of microwave signals as well as a system for transmitting or receiving microwave signals comprising a planar antenna equipped with such an antenna output, and finds an important application in systems for reception of 12 gigahertz television signals, in particular of television signals retransmitted by means of geostationary satellites.
  • French patent application n ° 82 04 252 previously filed by the applicant On March 12, 1982 describes a planar microwave antenna comprising an array of radiating or receiving elements produced on the one hand from three layers and on the other hand from two supply networks placed respectively between these layers for receiving signals. More specifically, the elements include a first layer with a first circular recess, first and second networks of microwave transmission lines located on either side of this first layer and coupled for the reception of signals with each recess along two perpendicular axes.
  • a first object of the invention is therefore to propose an antenna output for a planar antenna with arrays of elements in which the drawback mentioned above is completely eliminated.
  • the invention relates to, in a system for receiving, or transmitting taking into account the reciprocity nature of the antennas, microwave signals with orthogonal polarizations, an antenna output for a planar antenna with an array of receiving elements produced in two networks of microwave transmission lines and three plates arranged so that the first plate comprises first recesses, that the first and second networks of transmission lines are planar, situated on either side of this first layer and, for the reception of the signals, coupled with each of the recesses by as many distinct ends forming excitation probes along two perpendicular axes, and that the second and third plates are located on the other side respectively of one and the other of these networks and include second and third recesses aligned with the first, these third recesses being short-circuited in a plane para It lies on the faces of the plates, and these plates being metallic or dielectric with metallization of the walls of the recesses, said antenna outlet being characterized in that the opposite single end of each of the two networks of transmission lines also forms an excitation probe and is coupled to
  • the structure thus proposed ensures, thanks to the presence, on the back of the antenna, of an element inverted with respect to the receiving elements of the front face, the reshaping, the rigorous synchronization of the signals traversing respectively each network of lines of transmission: in fact, in this element inverted but otherwise similar to the others, the excitatory probes reemitting the signals they carry have the same "vertical" deviation as those of the elements on the front face, deviation which is equal to the thickness of The central plate.
  • This provides a broadband antenna output.
  • Another object of the invention is to provide an antenna outlet located in the center of the latter and therefore avoiding the installation of additional transmission line lengths, which would adversely affect the efficiency of the antenna.
  • the invention relates either to the antenna output which has just been described, with three plates and two networks of transmission lines, or, more simply, to an antenna output for a planar antenna with an array of receiving elements.
  • the planar microwave antenna according to the invention comprises, with reference to the figures, an array of receiver elements produced in the following manner.
  • a first layer 10 in which circular recesses 11 are provided, arranged in a two-dimensional network, are placed the conductive strips of two networks 20 and 30 of transmission lines, electrically independent and each carried by one thin dielectric sheet providing mechanical support for these Line networks.
  • a second layer 40 with circular recesses 41 and a third layer 50 with circular recesses 51 are provided respectively.
  • the recesses 41 and 51 are located opposite the recesses 11.
  • the recesses 51 of the third layer are short-circuited in a plane 52 parallel to the faces of the layers 10, 40, 50, to a depth of course less than the thickness of The layer 50, so as to constitute a reflective plane for the received microwave signals.
  • the recesses 41 end here, without this provision being essential, by a tapered flare 42 which contributes to reinforcing the gain.
  • the first, second and third layers 10, 40, 50 are either metallic, or made of dielectric material with metallization of all the walls of the recesses 11, 41, 51 which pass through them respectively.
  • the ends of the networks 20 and 30 of suspended ribbon transmission lines are arranged, on the receiving element side, along two perpendicular axes opposite the recesses of these receiving elements. These ends (not shown here because of the increase in complexity of the figures which would result therefrom) form in a known manner two exciting probes, carrying out in each of the elements The guide-network coupling which allows the reception of the microwave signals coming from the medium of spread; The penetration lengths of these probes can possibly be different from each other in order to optimize this coupling. From these ends which are equal in number to that of the receiving elements, Networks 20 and 30 progress in successive stages of combination towards a single opposite end, 121 and 131 respectively, constituting a point of convergence reached after electrical paths of equal Length. These two ends 121 and 131 collect, for one, the set of microwave signals received with a fixed linear polarization, respectively, and for re au T, the set of received microwave signals having linear polarization perpendicular.
  • a single circular waveguide 60 located here in the center of the rear face of the antenna, is then associated with these two ends 121 and 131 in the following manner.
  • this waveguide 60 occupies a position opposite to that of the waveguides formed in the receiving elements by the association of successive recesses 41, 11, 51, which means, more precisely, that this guide 60 , oriented towards the rear of the antenna, successively comprises a circular recess 65 in the rear layer 50 of the antenna, a circular recess 61 in the central layer 10, and a circular recess 64 in the front layer 40.
  • terminal sections 122 and 132 of the ends 121 and 131 of the transmission networks 20 and 30 are put in place opposite the recesses 65, 61, 64, in a similar manner to places opposite ends of the networks 20 and 30 in each of the receiver elements oriented towards the front of the antenna, so as to also constitute excitation probes. It then appears clearly now that, if one of the networks, in this case, is reached first by the microwave signals arriving from the propagation medium and penetrating into the receiving elements, the advance phase shift created in this network.
  • the microwave signals received being thus again rigorously in phase, it only remains to place in the waveguide 60 a depolarizing structure (not shown, because of known type: it is generally a dielectric wafer placed longitudinally and diametrically in the guide), then a mode separator (therefore having two outputs as symmetrical as possible towards two frequency converters) to again dispose of microwave signals with orthogonal polarizations which had been emitted (or retransmitted by the intermediary geostationary satellites).
  • the mode separator can be for example such as that described in the article "A wide-band square-waveguide array polarizer" published in The review IEEE Transactions on Antennas and Propagation, May 1973, pages 389 to 391 (see in particular La figure 1 of this document).
  • the two frequency converters, or reception heads, grouping the electronic circuits associated with the antenna can be in particular, in the case of the reception of television signals at 12 gigahertz transmitted via satellites, of the type of the head reception described in The review "L'Onde Electrique", volume 62, n ° 3, March 1982, pages 39 and 40.
  • the present invention is not limited to the embodiment described above and shown, from which variants can be proposed without departing from the scope of the invention.
  • the proposed antenna output remains advantageous even for an antenna called to receive signals of only one type of polarization and comprising for this purpose only a single network of transmission lines enclosed between two plates; indeed, even in this case, the proposed structure remains very economical, for the reasons indicated above, compared to current solutions with additional transmission lines and external connectors.
  • the invention extends to any system for receiving microwave signals comprising a planar antenna as described, the choice of the example of 12 gigahertz television signals not being limiting of the operating frequency or of the nature of this system (it can be incorporated into terrestrial as well as satellite transmission networks).
