Definitions

  • the present invention falls within the general framework of consolidation of radio functions on aircraft.
  • the antennas linked to these functions are different technologies.
  • the aerials intended for the MLS Omni system are of the "quarter whip" type while the radiating elements of the L1 GPS systems or GLONASS are mainly formed by structures monolayers with microstrips of the patch type printed on substrates with high dielectric permittivity.
  • GLONASS is offered from the GPS antenna, its performance are not certified.
  • the object of the invention is to overcome the aforementioned drawbacks by offering a unique multilayer antenna structure, very compact, adapted to aeronautical constraints and respecting specifications of the GPS L1, GLONASS and MLS Omni functions when taken in isolation.
  • the subject of the invention is a printed antenna multifunction for reception of radio waves emitted by GPS, GLONASS and MLS radio navigation systems, characterized in that it includes first, second and third patches circular parallel to each other and superimposed in this order above of the same ground plane which is parallel to them, the centers of patches being aligned on the same z'z axis perpendicular to the plane of the three patches, the patches being separated from one another by thicknesses a dielectric material forming a substrate for each of the patches, and in which the first and second patches form with the plane mass the antenna structure for receiving GPS waves, GLONASS, the MLS receiving antenna structure being formed by the third and second patches, the second patch serving also of ground plan for the MLS antenna structure, the third patch of the MLS structure having a diameter smaller than that of the first and second patch of the GPS structure, GLONASS, and in what the surface dimensions of the dielectric substrate separating the third and second patches are lower than the first and second patch and in that it includes a first ground wire connecting the
  • the invention has the advantage that it allows from a same radiating element consisting of a printed antenna with two circular patches superimposed, on identical substrates, to realize the functions of the GPS L1 and GLONASS systems with performance radio receivers that comply with the ARINC standard 743A. It also has the advantage that it provides the function MLS Omni with a single printed antenna with circular patch and central reception, operating on a higher mode, the mode TM020 whose radiation is of the monopolar type which allows a grouping of radiating elements by superposition.
  • Figure 1 a diagram representing the grouping by superposition according to the invention of a GPS antenna L1, GLONASS and an MLS Omni antenna.
  • Figures 2a and 2b an embodiment of an antenna adapted according to the invention to the reception of radio waves from L1 and GLONASS GPS systems.
  • Figures 3a and 3b the addition of an antenna structure suitable for receiving radio waves from the MLS system Omni.
  • FIGS. 4a and 4b of the gain curves of the structure antenna according to the invention at the frequencies 1572 MHz and 1628 MHz of reception of GPS L1 and GLONASS signals.
  • Figure 4c the angular directions ⁇ of the survey plans gains used for plotting the curves in Figures 4a and 4b.
  • Figure 5 a gain curve of the antenna structure MLS of the invention.
  • Figure 6 a final embodiment of the antenna according to the invention provided with coaxial sockets for signal routing detected to receiving circuits.
  • the antenna according to the invention which is represented according to the block diagram of Figure 1 consists of two structures superimposed antennas referenced 1 and 2 above the same ground plan 3.
  • the antenna structure 1 is adapted to the reception of L-band signals from GPS or GLONASS systems while the antenna structure 2 is suitable for receiving signals from MLS Omni system.
  • the antenna structure 1 is shown in Figures 2a and 2b in top view and in profile view along section aa '.
  • She includes a first patch composed of a conductive film 4 deposited on the upper face of a dielectric substrate 5 whose face lower, parallel to the upper face is fully metallized to form a ground plane 3.
  • the conductive film 4 has a shape circular in order to obtain a reception diagram with symmetry of revolution.
  • Coaxial links connect output ports 6 and 7 to inputs 8 and 9 of an external 3 dB coupler 10.
  • Output ports 8 and 9 are connected respectively at points A and B of the conductive film 4 by metallized holes crossing the thickness of the substrate 5.
  • the points A and B are arranged respectively on two perpendicular axes x ', x and y'y at the same distance d from the center O of the conductive film 4 to produce two signals in phase quadrature.
  • the sign of the phase shift between the two quadrature signals determines the right or left direction of the polarization.
  • the signals applied to the two inputs 8 and 9 of the coupler 10 come out recombined into a single signal on the output 11 of the coupler 10. The latter is charged in a known manner by an adaptation resistance R.
  • a second dielectric substrate 12 is placed above of the first conductive film 4 and a second patch in the form of a circular conductive film 13 centered on an axis z'z passing through the center O of the conductive film 4 and perpendicular to the planes of the two conductive films 4 and 13, is deposited on the outer surface of the second 12 substrate parallel to the first conductive film 4.
  • a ground wire 14 connects the center O of the film 4 to the ground plane 3 so as to ensure good galvanic grounding of the antenna on the equipment on which it is intended and so as not to disturb the TM 10 modes and TM 01 for receiving the antenna, their vertical electrical component being zero at this point.
  • a third substrate dielectric referenced 15 in Figures 3a and 3b is placed above conductive film 13 and a third patch in the form of a film conductor 16 of circular shape centered on the axis z'z is deposited at above the dielectric substrate 15.
  • the plane of mass of the MLS antenna consists of the second conductive film 13.
  • Signal recovery MLS is carried out by a coaxial plug coming to engage in a metallized hole 18 connecting the center of the conductive film 16 through the thickness of the three substrates 5, 12 and 15.
  • the diameter of the conductive film 16 forming the third patch either lower than the conductive films of the other two patches and that the surface dimensions of the dielectric substrate 15 interposed between the second and third patches 13 and 16 are lower than those of the conductive film of patches 4 and 13.
  • FIG. 6 A representation of the antenna according to the invention provided with coaxial sockets P1 P2 and P3 for the connection of metallized holes 6,7 and 18 to external receiving circuits is shown in Figure 6 where the elements homologous to those of FIGS. 3a and 3b are marked with the same references. This provision ensures the connection of the ground wire 14 through the outer conductor of the coaxial link.
  • Total thickness: h 11 mm
  • This arrangement makes it possible to obtain diagrams of radiation of the GPS L1, GLONASS function performed with the structure of FIGS. 2a and 2b which are not disturbed by the presence of the MLS structure and which meet the ARINC standard, as as shown in FIGS. 4a and 4b, the gain of the GPS structure L1, GLONASS at frequencies 1572 MHz and 1628 MHz remains much higher than minimum gain required by the ARINC standard in all plane directions represented in FIG. 4c, having in common the axis z'oz, the original plane being that which contains the x'ox axis.
