Definitions

  • the present invention relates to a network antenna on a printed circuit.
  • a network antenna on a printed circuit appears as a plate, consisting of one or more superposed printed circuits, one of which has on one of its faces radiating dipoles, and on the other face an energy distribution tree. .
  • These printed circuit boards have a surface area substantially equivalent to the parabolic antennas of equivalent gain and must be rigidly held by a rear structure.
  • This rear structure prevents “deviations” and deformations due to wind and gravity, it requires an interface with the printed circuit.
  • the object of the invention is to lighten or even eliminate this rear structure by stiffening the antenna by a front plate with radiating openings.
  • European patent application EP-A 0 089 084 describes a receiver or radiating element of microwave signals with left and right circular polarizations successively comprising a first insulating layer in which is provided a mini-horn of square section whose inner surface is metallized, a first supply network for the reception of signals whose polarization is of a first type, a second insulating layer in which a mini waveguide is provided with the same square section on the side of the first network and of rectangular section with the other end, and also 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 is provided a 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 invention for its part, provides a network antenna on a printed circuit, of elongated shape, comprising at least one printed circuit, this first printed circuit consisting of a substrate on which radiating elements are arranged on a first face, a energy distribution shaft on a second face, and an elongated front structure, superimposed on the first face of this printed circuit, this front structure consisting of a substrate pierced with radiating openings arranged facing the radiating elements of this printed circuit, characterized in that the substrate which constitutes the front structure is at least metallized on the surface and in that traps, made up of annular grooves, are placed around the outer ends of the openings drilled in the front structure.
  • the invention comprises a second circuit which is superimposed by its first face on the second face of the first printed circuit, a ground plane being arranged on the second face of this second printed circuit.
  • the proposed solution makes it possible to limit the couplings between radiating elements, a drawback that is encountered on conventional network antennas.
  • this structure makes it possible to place traps around the openings.
  • the front structure has the advantage of protecting the antenna from mechanical shock (projectiles, transport, etc.) and makes it possible to tension a flexible radome without difficulty.
  • the known art network antenna represented in FIG. 1, is in the form of a plate made up of a first 10 and a second 11 superposed printed circuits, the first having on one of its faces of the radiating dipoles 12 and on the other a power distribution shaft 13 which makes it possible to supply these dipoles by bushings 14 to allow these dipoles 12 to emit radioelectric radiation and the second having on its second face, which is external, a ground plane 15.
  • the size of the radiating dipoles 12, of the energy distribution shaft 13, and of the ground plane 15 have been voluntarily increased for the clarity of the drawing, but these are simple metallic deposits.
  • this antenna has a rear structure 16 which makes it possible to stiffen it.
  • the array antenna according to the invention also includes two printed circuits 10, 11 as described above, but the rear structure 16 has been lightened.
  • This antenna further comprises a front structure 20 consisting of a metal plate, pierced with openings 21 of conical shapes, superimposed on the first face of the first printed circuit 10, each opening 21, of direction perpendicular to the surface of this first circuit printed 10, facing a radiating element 12.
  • a radome 22 protects the antenna in bad weather.
  • the front structure 20 makes it possible to stiffen the antenna, and to vary the radiation pattern of the antenna, using different directions of opening.
  • Annular grooves 30 are drilled in the metal plate, which composes the front structure 20, around the outer ends of the openings 21 to form traps which allow the radiation pattern to be symmetrical.
  • FIG. 3 represents a variant of the invention in which the radiating elements are consist of a patch 23 disposed at the end of a small rod 24, which makes it possible to modify the radiation pattern of this antenna.
  • the antenna according to the invention can be used for example in a frequency range from 1 GHz to more than 20 GHz. The higher the frequency, the closer the radiating elements and the more the thickness of the front structure decreases.
  • the front structure 20 can consist for example of a plastic substrate whose surfaces have been metallized.
  • the rear structure 16 is no longer compulsory, because the antenna can be fixed using the front structure 20.
  • the elements can be, as shown in Figure 2, radiating dipoles 12 linked to the distribution shaft 13 by the printed circuit. But it can also be small antennas, linked to the distribution shaft by the printed circuit, or any other form of radiating elements.
  • the radiating openings 21 can take shapes other than conical, for example cylindrical shapes, the dimensions of which will depend on the frequency and the desired gain and the axis of each opening can be oriented at will relative to the direction normal to the plate supporting the radiating elements, in order to conform the antenna lobe as desired. These openings can be arranged with respect to each other in a manner different from that shown in FIG. 3. In fact their position depends on that of the radiating elements on the first printed circuit.
  • the antenna of the invention has been shown in the form of a plate, but it can have any shape: cylindrical, conical, and even a variable thickness, allowing it to adapt to any existing structure.
