Definitions

  • the present invention relates to an element for receiving microwave signals with orthogonal polarizations or, according to the principle of reciprocity of antennas, a radiating element for such signals produced in a similar manner, this element comprising on either side of a microwave transmission line. the end of which constitutes an excitation probe a dielectric layer.
  • the invention also relates to a planar antenna comprising an array of such juxtaposed elements, and finds in particular an application in the field of reception of 12 gigahertz television signals retransmitted by means of satellites.
  • a reception element or an antenna composed of a network of reception elements
  • a radiating element as a radiating antenna
  • a planar antenna comprising such elements is described in the article "New wideband high-gain stripline planar array for 12 GHz satellite TV" by E. Rammos, published in the journal Electronic letters, Volume 18, n ° 6, 18 March 1982, pages 252 and 253. Despite encouraging performance, this antenna is not entirely satisfactory with regard to its performance.
  • the object of the invention is to propose a receiver element and an antenna (composed of a network of such elements) in which the efficiency is improved.
  • the invention relates to a receiving or radiating element as defined in the preamble and characterized in that it also comprises a second transmission line and a third dielectric layer arranged such that this element comprises respectively, on either side of the first layer in which a first recess is provided, the first and second microwave transmission lines arranged along two perpendicular axes, and also comprises, the other side of one of the transmission lines, the second layer with a second recess located opposite the first and, on the other side of the other transmission line, the third layer with a third recess located opposite of the other two but short-circuited at a distance from this other transmission line less than the thickness of this third layer so as to constitute a reflective plane, the first and second transmission lines being constituted on the one hand by grooves produced symmetrically in the adjacent layers and on the other hand of conductive tapes carried in the median plane of these lines and whose ends penetrate followed nt said axes inside the recesses to constitute the excitation probes achieving with the propagation medium a coupling
  • This element comprises the following structure: on either side of a first layer 10, in which a first recess 11 (in this example, circular) of metallized interior surface is provided, a first transmission line 20 and a second transmission line 30 consisting of conductive strips 21 and 31 carried in the median plane of grooves 22 and 32 by a thin dielectric sheet 23 and 33 providing mechanical support for the conductors.
  • the end of the central conductors of these suspended ribbon microwave transmission lines referenced 24 and 34 penetrates along two perpendicular axes inside the recesses, thus constituting two excitation probes which achieve coupling with the propagation medium allowing reception of the signals microwave; these two ends have a penetration length opposite the recess which is distinct, as specified below.
  • the other end of each line constitutes its output, in the case of reception.
  • a second layer 40 also comprising a second recess 41 of metallized interior surface located opposite the first recess 11, and, similarly, on the other side of the line 30 is provided a third layer 50 with a third recess 51 of metallized interior surface located opposite the other two.
  • This recess 51 is short-circuited in a plane parallel to the faces of the layers, at a distance from the line 30 of course less than the thickness of the layer 50, so as to constitute a single reflective plane for the received microwave signals.
  • the element thus described behaves like a waveguide-line transition with a suspended substrate, in which the axis of the guide is perpendicular to the plane of the lines.
  • the first, second and third layers 10, 40 and 50 may be metallic, or else made of a dielectric material with metallization of the walls of the recesses 11, 41 and 51 which pass through them respectively.
  • the diameter of the recesses must be both sufficiently small, relative to the wavelength associated with the frequency of the microwave signals, to avoid the appearance or attenuate the propagation of the undesirable higher modes and sufficiently large to allow the propagation of the main mode in the considered bandwidth.
  • the recess 41 ends with a tapered flare 61 possibly covered with a polyurethane type screen, these arrangements helping to enhance the gain and improve the characteristics of the radiation.
  • a 3 dB hybrid coupler can be provided, with its two inputs connected respectively to the outputs of lines 20 and 30 and its two outputs providing said right or left circularly polarized signals. It is also possible, instead of the coupler, to provide a depolarizing structure in front of the receiving element. Finally, without a coupler or depolarizing structure, signals are obtained having two perpendicular linear polarizations.
  • the present invention is not limited to the receiving or radiating element described above, from which variants can moreover be proposed without thereby departing from the scope of the invention.
  • the invention also relates to a planar microwave antenna which is composed of a whole network of such receiving elements, the conditions seen previously and relating to the diameter of the recesses being then supplemented by the fact that, for a positioning of the elements satisfactorily next to each other, this diameter must be sufficiently small (compared to the wavelength in vacuum associated with the frequency of the microwave signals) so that the distance between the elements can be less than said wavelength. It is indeed only with this last condition that the appearance of undesirable secondary lobes, called lobes of the network, is avoided.
  • this radiating or receiving antenna is quite similar to that of the radiating or receiving element, and everything that has been said above about it can be transposed as is in the case of the antenna , except for transmission lines.
  • the antenna no longer comprises only two transmission lines leading from the receiving element to two output connections but, more precisely, two networks of microwave transmission lines, electrically independent like lines 20 and 30 and intended , like them, to ensure the transmission of the microwave signals received towards the electronic circuits external to the antenna.
  • a 3 dB hybrid coupler can be provided (or, instead of the coupler, a depolarizing structure in front of the entire antenna) for the reconstruction of the polarized signals. left and right circular.
  • These networks are each composed, in a manner well known in numerous embodiments (see in particular the network structure shown in FIG. 1 of French patent application No. 7011449), of a succession of combination stages. If the antenna comprises n receiving elements, the first n ends of each network are used, as already described for a single receiving element, for coupling with the propagation space of the signals to be received, while the opposite opposite end of each of the two networks, the point of convergence of all the transmission lines across the successive combination stages, is connected to the electronic reception circuits external to the antenna (and, for example, in the first place to one and the other of the two entrances from 3 dB coupler which allows the reconstruction of signals with right and left circular polarizations).
  • An antenna produced in this way lends itself particularly well to a low-cost modular embodiment, in which elementary blocks forming subsets of receiving elements can be used in an appropriate number and by joined assembly for the constitution of antennas of dimensions , gain and directivity diagram well determined, either for example a symmetrical antenna of square shape, or more generally asymmetrical antennas, in particular of rectangular shape, having different radiation patterns in two orthogonal planes.
  • This last characteristic is particularly interesting for the antennas of reception of television signals with 12 gigahertz retransmitted by satellites, since an opening with 3 dB lower than 2 ° is in this case, essential only in the equatorial plane to separate the signals of two "distant" satellites, in this plane, of 3 ° (see the recommendations of the CCIR, Geneva, 1977).
  • Another modular type embodiment can also be advantageously proposed: if it is desired to have a planar antenna which must receive or transmit microwave signals only of one type of polarization (linear, or circular while maintaining a depolarizing structure) , said antenna can be obtained from that described above simply by omitting the central layer 10 and one of the two supply networks 20 or 30.
  • the application of the invention to the reception of 12 gigahertz television signals retransmitted by satellites is not limiting, although the antenna described is in fact mainly intended for coupling with one or more reception heads of such signals (an example of these reception heads is described in particular in the review "L'Onde Electrique", volume 62, n ° 3, March 1982, pages 39 and 40).
  • the invention is applicable to all kinds of networks of purely terrestrial microwave transmission, and on the other hand the choice of an example of application at the frequency of 12 gigahertz is not exclusive of any other possible operating frequency in the microwave range, linked to the intended application.
