Definitions

  • the present invention relates to a receiver element for microwave signals with circular polarizations, produced in a planar structure according to the printed circuit technique associated with a dielectric support, as well as a planar antenna comprising an array of such elements.
  • a reception element or an antenna composed of a network of reception elements
  • a radiating element as a radiating antenna
  • Patent of the United States of America No. 4,054,874, filed on June 11, 1975 and issued on October 18, 1977 in the name of the transferee Hughes Aircraft Company describes, among other achievements, a microwave antenna composed of elements allowing the emission or reception of circularly polarized signals, each element being composed in this case of a pair of conductive dipoles associated in cross by their central part to constitute a single device, coupled to the ends of corresponding transmission lines.
  • the lengths of the transmission lines differ by a quarter of the wavelength associated with the frequency of the signals transmitted or received, so that these useful signals are in quadrature of phase.
  • the object of the invention is to propose a new structure for an element for receiving microwave signals, these signals being able to be indifferently with left circular polarization or with right circular polarization, as well as an antenna composed of such elements.
  • the receiving element also comprises in the same median plane at least two dipoles each consisting of an electrically conductive strip of length substantially equal to half the wavelength of the signals to be received and arranged along said axes to allow effective coupling between these dipoles and the corresponding triplate transmission lines, an insulating sheet being interposed between these dipoles to electrically separate at least the portions of these two dipoles which are opposite one another, and this pair of dipoles being located opposite the recesses.
  • both of these two structures have the same essential advantages, namely the possibility of receiving signals with circular polarization left or right at the same time, and the almost absence total coupling between the circuits corresponding to these two types of received signals since at the center of the dipoles, the coupling is only capacitive, and precisely where the electric field is zero or very weak.
  • the receiving element shown in FIGS. 1a and 1b is produced according to the technique of the printed circuit associated with a dielectric support and comprises the following symmetrical planar structure.
  • a first plane 10 said median and which constitutes a plane of symmetry for the structure described, there are provided two completely separate dipoles 1 and 2, each consisting of an electrically conductive strip whose length is substantially equal to half the wavelength of the microwave signals to be received.
  • These dipoles 1 and 2 are here arranged in an electrically symmetrical cross, along two perpendicular axes, and separated by a thin insulating sheet 11 (the dimensions of this sheet can, if desired, be limited to those necessary to isolate one of the other the portions of the dipoles which are actually opposite one another).
  • This same median plane 10 also contains two triplate lines 3 and 4, intended to ensure the transmission of the signals received by the dipoles to a reception device not shown. These two lines 3 and 4 must be independent and have no electrical connection between them.
  • a first end 3a of line 3 is located opposite one end of dipole 1 and aligned with it, so as to achieve with this dipole a capacitive coupling and, similarly, a first end 4a of line 4 is located opposite one end of the dipole 2 and aligned with it, to also carry out a capacitive coupling.
  • the second ends 3b and 4b of line 3 and line 4 are fitted with connectors 5 and 6 respectively and each constitute a connection intended to be connected to the electronic reception circuits, not shown.
  • the receiving element finally comprises, on either side of the median plane 10, two planar dielectric layers 12 and 13 each comprising on their outer face an electrically conductive surface, 14 and 15 respectively, which constitutes a ground plan.
  • these conductive surfaces are provided non-conductive recesses 7 and 8 respectively, the recess 7 in the surface 14 revealing the dielectric layer 12 and the recess 8 in the layer 15 revealing the dielectric layer 13.
  • the recesses 7 and 8 are circular, with a diameter slightly greater than the length of each dipole, and are located opposite the dipoles so that they are entirely contained in the cylindrical contour which these recesses define.
  • the line-dipole and space-dipole couplings can be strong simultaneously, thanks to the presence of ground planes preventing parasitic radiation from the three-plate transmission lines and that of the recesses authorizing the reception exclusively of a look at the dipoles;
  • the reception is that of circular polarization signals, both left and right, since the proposed structure does not eliminate either of the two possibilities, the separation of one or the other taking place only later;
  • the coexistence of these two possibilities of reception of signals of different circular polarizations is accompanied by good electrical insulation between the corresponding circuits, thanks to the complete separation of the two dipoles 1 and 2 (opposite to that which is described in patent No. 4,054,874 already cited).
  • the element can be equipped with a reflecting metallic surface 16, arranged on one side of the element (see FIG. 1b) and parallel to the median plane 10 of the latter.
  • This conventional arrangement (see for example FIG. 2 of French patent application No. 78 31 879) reinforces the reception efficiency, the waves received which reach said surface 16 being returned to the dipoles.
  • This reinforcement is optimal if the distance between this surface 16 and the median plane 10 is equal to or substantially equal to a quarter of the length I wave associated with the frequency of the useful signals to be received (by equal, we mean electrically equivalent given the media between the surface 16 and the plane 10, there is indeed an air layer and a dielectric layer, the layer 13).
  • the element which has just been described can, in accordance with the invention, be used for the production of a planar microwave antenna composed of a whole array of such elements, according to the same technique of the printed circuit associated with a dielectric support, with the structure described below with reference to Figures 3a and 3b.
  • a first median plane 100 is provided a whole set of (mxn) pairs of dipoles 1 m, n and 2 m, n (referenced in the same way as the dipoles 1 and 2 of the element considered in isolation, but with the indices m, n to characterize them each, m and n being, in the example here considered, equal to 25, but which can naturally take other values).
  • the dipoles 1 m , n and 2 m , n are, as before, arranged in an electrically symmetrical cross, along two perpendicular axes, but being completely distinct, with electrical insulation provided again by an insulating sheet (i.e. a single sheet of the same surface area as the complete antenna, or pieces of insulating sheet provided only in the dipole area, these pieces possibly themselves being able to be limited to dimensions just sufficient for the portions of dipoles which are facing each other are effectively isolated from each other).
  • an insulating sheet i.e. a single sheet of the same surface area as the complete
  • the 2. (mxn) dipoles (1 m, n ), (2 m, n ) each consist of a conductive tape whose electrical length is substantially equal to half the wavelength of the microwave signals to be received.
  • the dipoles are grouped into ( mxn ) first dipoles 1 m, n and into (mxn) second dipoles 2 m, n , all the first dipoles on the one hand being parallel to each other d 'one pair of dipoles to the other, all the second dipoles on the other hand also being parallel to one another from one pair of dipoles to the other.
  • the median plane 100 contains, in addition to the (mxn) pairs of dipoles, the association of two networks of triplate microwave transmission lines, not shown to simplify the figures. These networks are, like lines 3 and 4, electrically independent of each other, intended to ensure the transmission of the signals received by the dipoles to the reception device (not shown), and for this purpose each composed of a succession of stages of combination of the received signals. Such networks are known in numerous embodiments (see, by way of nonlimiting example, the network represented in FIG. 1 of French patent application No. 70 11 449).
  • the first (mxn) ends of one of the networks are located opposite one end of the 1 m , n dipoles (mxn) (the same for all these dipoles) and each aligned with the corresponding dipole end, so that perform a capacitive coupling with the dipoles concerned; similarly, the first (mxn) ends of the other network are located opposite one end of the (mxn) dipoles 2 m , n and aligned with them respectively, to also perform a capacitive coupling of the dipoles to the networks.
  • the opposite end, or second end, of the first network is the point of convergence ⁇ of all the transmission lines making up this network; it is equipped with a first connector and constitutes a connection intended to be connected to the electronic circuits of the reception device; it is the same for the second end of the second network, equipped with a second connector.
  • the antenna finally comprises, on either side of the median plane 100, two planar dielectric layers 112 and 113 each having on their outer face an electrically conductive surface, 114 and 115 respectively, which constitutes a plane massive.
  • These conductive surfaces 114 and 115 each comprise a set of (mxn) non-conductive recesses revealing the corresponding dielectric layer 112 or 113.
  • These 107 m, n and 108 m , n recesses are circular, with a diameter slightly greater than the length of the dipoles and are located opposite them, so that each pair of dipoles is entirely contained in the delimited cylindrical contour. by the corresponding recesses.
  • the antenna thus proposed has the same front ages as the single element described above (quality of the useful couplings, almost total absence of harmful couplings, possibility of simultaneous reception of signals with circular polarization left or right, variants in the characteristics of the dipoles , etc ).
  • the element and the antenna as described comprise dipoles, but an embodiment without dipoles (all other things almost equal) can be proposed, with the same essential advantages recalled above.
  • the dimensions of the recesses are such that they become resonant diaphragms for the frequency of the signals to be received, the intensity of the coupling diaphragms-triplate lines then being linked to the importance of the penetration of the end of these lines in the cylindrical contour limited by the recesses.
  • the element or antenna according to the invention is equipped with a metallic reflecting surface such as 16 (see the element in FIG. 1b), this surface can, in particular to avoid any coupling between neighboring receiving elements, be limited by (mxn) lateral metal walls with a diameter slightly greater than that of the recesses. These walls are perpendicular to the reflecting surface which now constitutes a bottom wall and placed on the ground plane of the corresponding dielectric layer (see Figure 4 where an element is shown equipped with such a wall 17).
  • the element or the antenna can also be equipped, in particular to avoid any horizontal radiation from one receiving element to another, with a metal crown 18 of diameter identical to that of the wall 17 and placed on the ground plane of the other dielectric layer.
  • the element and the antenna which have been described above find an essential application in the field of television transmitted by satellite, for the equipment of systems for receiving these television signals.
