Definitions

  • the present invention relates to wireless communication devices with antenna (s) -cornet (s), more particularly intended to ensure communications in the millimeter frequency bands.
  • the invention aims more particularly to improve the integration of one or more horn antennas on a printed circuit (in English " Printed Circuit Board " acronym PCB).
  • V-band the frequency band of the order of 60 GHz, called V-band, is a preferential solution, by its frequency bandwidth, of the order of 10 GHz, making it possible to obtain bit rates up to 6 Gbps.
  • Such a rate is appreciable for making wireless links for short ranges, typically of the order of one meter, which can replace wired solutions, such as as HDMI (acronym for " High Definition Multimedia Interface ”) or USB-C (Universal Serial Bus Type C).
  • antennas are essential components in transceiver systems.
  • miniaturization and antenna performance are essential for their integration with current and future transceivers.
  • a horn antenna can be a response to this demand by its intrinsic compactness, its good radio performance, but especially by its low losses in the millimeter frequency bands.
  • a horn antenna is a guide device with a progressive section consisting of a straight waveguide, for example of rectangular section, extended at one of its ends with a radiating opening of generally frustoconical shape. or truncated pyramid.
  • An advantageous type of horn antenna is one with one or more ribs inside the opening, which makes it possible to increase the bandwidth of the antenna.
  • the object of the invention is to respond at least in part to this need.
  • the horn antenna is a surface mounted component (CMS) via the flange (s) supported by the support of the PCB and fixed on the latter, and the horn antenna is arranged with the waveguide and the radiating aperture on either side of the PCB support and with each rib in direct contact with or near a track of the PCB, so as to allow a direct connection or a coupling capacitive between them.
  • CMS surface mounted component
  • the horn antenna is molded in one piece.
  • the invention essentially consists in defining a horn antenna whose structure allows it to be made by integral molding of a usual material, in particular a metallized plastic or a zinc-based alloy, while being of small dimensions. Its rear shape with a recess at the rectangular portion of the waveguide and its fixing flanges, allow it to be mounted as a surface mounted component (CMS) usual vertical PCB and makes it perfectly compatible with the classic processes of setting up by "pick-and-place".
  • CMS surface mounted component
  • ribs make it possible to reduce the dimensions of the radiating opening (horn) without having to implant an additional dielectric element, to generate the two types of horizontal and vertical polarizations, and to increase the polarization purity.
  • the shape of the ribs can be easily optimized to obtain the best possible performance of transmission of HF signals (Hyper Frequencies).
  • the CMS mounting of the horn antenna also allows to have a very small footprint in height because the radiating aperture can be centered on either side of the PCB support plane.
  • the horn antenna said vertically polarized, has ribs arranged in the plane of symmetry of the end of its radiating aperture which is perpendicular to the plane of the PCB.
  • the horn antenna said horizontally polarized, has ribs arranged in the plane of symmetry of the end of its radiating aperture which is perpendicular to the plane of the PCB.
  • the PCB comprises at least one indentation, of complementary shapes with at least a part of the opening radiating from its small base, in which the radiating opening is at least partially embedded, the guide of right wave surrounding in the extension of the bottom of the notch at least one conductive track on the face of the PCB on which the horn antenna is mounted.
  • the horn antenna is adapted to radiate in the plane of the PCB.
  • the waveguide of each horn antenna has a recess, so as to confer an asymmetry.
  • the horn antenna can be advantageously centered on the plane of the PCB support, so that its height (H), defined by the height of the radiating aperture, is substantially distributed for half (H / 2) of both sides of said support plane.
  • Each horn antenna is preferably fixed on the support of the PCB by brazing using a technique by reflow or wave.
  • the device comprises at least one alternation of two cornet antennas arranged side by side, one of which said vertical polarization has its ribs arranged in the plane of symmetry of the end of its opening radiating which is perpendicular to the plane of the support of the PCB, and the other said polarization horizontal has its ribs arranged in the plane of symmetry which is perpendicular to the plane of the support of the PCB.
  • one of the ribs of the vertically polarized horn antenna is in direct contact with a printed track while the other of the ribs is at a distance from the printed track.
  • the two ribs of the horizontally polarized horn antenna are in direct contact with the two printed tracks.
  • step d / is performed simultaneously with other components mounted on the surface of the PCB.
  • the invention also relates to a wireless communication apparatus for communications in the millimetric frequency bands, comprising at least two wireless communication devices described above, each comprising a number of n identical alternations of two horn antennas, the two devices being arranged facing each other over a short distance, of the order of 1 cm.
  • the invention finally relates to the use of the wireless communication apparatus as described above, for transmitting and / or receiving a number of n + 1 data streams in parallel at a frequency around 60 GHz.
  • a wireless communication device intended to provide transmissions / receptions of signals in the millimeter frequency bands, and more particularly at 60 GHz.

  • the support 20 of the PCB is advantageously provided with metal zones 25 around the end of each of the tracks 23, 24 and two indentations 26, 27 made on an edge of the support 20.
  • these indentations 26, 27 are in the general shape of isosceles trapezium.
  • the bottom 28, 29 of these notches is arranged near the end of each of the tracks 23, 24.
  • the support 20 of the PCB supports an alternation of two horn antennas 3, 4, each molded in one piece, which are distinguished by the inner ribs 32, 33; 42, 43 they comprise, as explained below.
  • the horn antennas 3, 4 according to the invention may advantageously be produced by injection molding a metallized plastic or even a metal alloy.
  • each antenna 3, 4 comprises a straight waveguide 30, 40 of rectangular section extended by a radiating aperture 31, 41 or truncated pyramid horn.
  • the end of each horn 31, 41 has two planes of symmetry P1, P2 perpendicular to each other.
  • each right waveguide 30, 40 has an asymmetry due to a recess 35, 45 on its lower part.
  • This recess 35, 45 allows vertical placement of each horn antenna on the support 20 of the PCB, advantageously compatible with a pick & place type of mounting process.
  • Two ribs 32, 33 or 42, 43 extend opposite one another in one of the symmetry planes P1, P2, over at least a portion of the length of the waveguide 30, 40 and the horn 31, 41.
  • Each antenna 3, 4 finally comprises peripheral zones 34, 44 around the waveguide 30, 40 and around a portion of the horn 31, 41. These peripheral zones 34, 44 form flanges for fixing or holding each horn antenna 3, 4 mounted in SMD surface component.
