Definitions

  • the present invention relates to the field of plastic waveguides for the propagation of waves of frequencies between 1 GHz and 10 THz, and more particularly relates to an improved assembly for the propagation of waves comprising such a plastic waveguide.
  • It also relates to a wired or wireless communication link for the transmission of high-speed signals, which comprises such an assembly.
  • Waves with frequencies between 1 GHz and 10 THz are non-ionizing radiations which can penetrate a wide range of non-conductive materials such as wood, plastic, ceramics or even paper.
  • Plastic waveguides have thus been reported for the propagation of terahertz waves.
  • Low loss materials are also used so as not to increase losses through attenuation due to propagation.
  • the size of the terahertz waveguides thus protected is also increased.
  • Dielectric coaxial waveguide disclose plastic dielectric waveguides comprising a central core and a shell separate from the core, or the core and the shell have different permittivities.
  • EP2958187A1 discloses a dielectric waveguide comprising a central core and a tube connected to the core with plastic dielectric supports, which can be made integrally with the tube.
  • the present invention relates to an assembly for the propagation of waves of frequencies between 1 GHz and 10 THz, simple in its design and in its operating mode, reliable and economical while allowing high-speed data transfer.
  • Another object of the present invention is a wired or wireless communication link comprising such an assembly for the propagation of waves of frequencies between 1 GHz and 10 THz, said link being inexpensive, offering a wide bandwidth and a high degree of mechanical reliability.
  • Another object of the present invention is a device for receiving / transmitting electromagnetic waves in the frequency band between 1 GHz and 10 THz comprising such an assembly for the propagation of waves.
  • the invention relates to an assembly for the propagation of waves of frequencies between 1 GHz and 10 THz.
  • this protective envelope truly isolates from the outside the waves propagating inside the waveguide and outside the waveguide, and consequently makes it possible to minimize the impact of disturbances. exterior on them.
  • this protective envelope also prevents access to the space or spaces in which the waves propagating outside the waveguide evolve. It is therefore possible to have one or more areas of contact of the assembly with the outside without significant loss of signal strength.
  • this protective envelope, or sheath is arranged concentrically with this waveguide.
  • this space or these spaces are under vacuum.
  • this space or these spaces can be filled with a dielectric material having a permittivity lower than the permittivity of said waveguide.

  • such a configuration of the protective envelope makes it possible to limit the contacts of the assembly with a flat surface and, consequently, limits external disturbances.
  • this cross section can also be chosen from the group comprising square, rectangular, elliptical, ...
  • Said waveguide having a cross-section in the form of a cross may be solid or have one or more holes.
  • a waveguide with a cross-section in the shape of a cross makes it possible to double the number of possible propagation modes compared to a waveguide with a rectangular section, while reducing interference phenomena, or cross-talk, to a minimum. This is obtained by virtue of the orthogonality of fields oscillating at the same frequency.
  • Such a configuration is particularly advantageous in the context of full duplex communication, that is to say communication without interference.
  • such a configuration makes it possible to improve the compactness of a communication system integrating such a device compared to fully multimode communication devices.
  • This or these holes can be filled with a dielectric material having a permittivity lower than the permittivity of said waveguide, which then contributes to the rigidity of the assembly for the propagation of the waves.
  • the protective envelope and the waveguide are made of polytetrafluoroethene (PTFE - Teflon®).
  • the protective envelope and the waveguide are made of at least one material chosen from the group comprising polyurethane (PU), polytetrafluoroethene, polyethylene (PE), polypropylene (PP), polystyrene (PS) , polycarbonate (PC), Mylar (PET), plexiglass (PMMA), polyvinyl (PVC), polychlorides, polyvinyls, Nylon (PA), acrylonitrile butadiene styrene (ABS), polyactic acid (PLA) and combinations thereof .

  • This set for wave propagation is one piece. Not resulting from the assembly of initially separate elements, this assembly advantageously exhibits increased mechanical strength and stability to ensure the guidance of the waves in the frequency band between 1 GHz and 10 THz.
  • such an assembly can also be obtained by any conventional method for manufacturing plastic parts such as by extrusion or by injection molding, and is therefore easy to manufacture. Its manufacturing cost is also low.
  • said protective envelope also comprises one or more irregularities for generating electromagnetic waves.
  • such an irregularity may consist of a local modification of the section of the protective casing.
  • the assembly for the propagation of waves can thus form a oriented antenna for wireless communications.

  • the present invention also relates to a device for receiving / transmitting electromagnetic waves in the frequency band between 1 GHz and 10 THz.
  • this device comprises an assembly for the propagation of waves as described above.
  • FIGS. 1 and 2 schematically represent an assembly 10 for the propagation of waves according to a particular embodiment of the present invention.
  • This assembly 10 comprises a waveguide 11 for guiding waves of frequencies between 1 GHz and 10 THz, which is made of a plastic material such as polytetrafluoroethene.
  • This waveguide 11 is here an elongated solid part having a straight cross-section in the shape of a cross, which advantageously makes it possible to double the number of propagation modes with respect to a waveguide with rectangular section.
  • the wave propagation axis is the longitudinal axis of this elongated solid part.
  • This assembly 10 also comprises a protective envelope 12, or sheath, which surrounds this plastic waveguide 11 by delimiting several spaces 13 - 16. Each of these spaces 13-16 is here delimited on the one hand by the inner wall of the protective casing 12 and on the other hand by external surfaces of the waveguide 11 with a cross-shaped section.
  • these spaces could be filled with a material having a permittivity lower than that of the waveguide.
  • This protective envelope 12 is here made of the same plastic material as the plastic waveguide 11, the assembly 10 for the propagation of the waves being in one piece. This assembly is here obtained by an injection molding process.
  • the waves propagating outside the plastic waveguide 11 are consequently contained in these spaces while being surrounded by the protective envelope 12, which thus forms a barrier protecting the latter from external disturbances.
  • this protective envelope 12 here has a thickness W of the order of 0.5 mm sufficient to effectively protect from external stresses, the waves propagating outside the waveguide 11.
  • this envelope is defined so as to be on the one hand sufficiently thick to protect the waves propagating in spaces and the waves propagating inside the waveguide from external disturbances, and on the other hand not too thick so as not to transform the envelope itself into a propagation medium for waves which would disturb the operation of the waveguide.
  • the Figure 3 shows an assembly 20 for the propagation of waves according to a second embodiment of the present invention.
  • This assembly 20 for the propagation of waves comprises a waveguide 21 for guiding waves of frequencies between 1 GHz and 10 THz.
  • This waveguide 21 is here an elongated solid part having a straight cross section in the shape of a cross provided with a central hole 22. This configuration advantageously makes it possible to increase the number of propagation modes and to minimize losses.
  • the figure 4 shows the calculated spatial distribution of the electric field for the first three modes of propagation for a frequency of 80 GHz and for set 10 for the wave propagation described in Figures 1 and 2 in the absence of external disturbance applied to the assembly.
  • the figure 5 illustrates a robustness test of the assembly 10 for the wave propagation of the Fig. 1 , in which two blocks 30, 31 filled with an aqueous solution locally surround the outer surface of the protective casing 12 in order to simulate the effect of a manual gripping of the latter.
  • These dielectric blocks 30, 31 have an electrical permittivity of eighty (80), which constitutes a major disturbance for the propagation of the waves in said assembly 10 for the propagation of waves.
  • the Figures 6 to 8 show the calculated spatial distribution of the electric field for the first three propagation modes for a frequency of 80 GHz and for set 10 for the wave propagation described in Figures 1 and 2 , when an external contact is applied to this assembly via the two blocks 30, 31 of dielectrics. These results were obtained from simulation software from ANSYS Inc., Canonsburg, PA 15317 USA.
  • the signal transmission is calculated on the one hand for an assembly comprising a cross-section waveguide of the Figure 1 for the first two modes of propagation, and on the other hand for a single waveguide of rectangular section. This transmission is calculated in the presence of blocks 30, 31 and in the absence of these blocks 30, 31.
  • the assembly and the waveguide of rectangular section have a longitudinal dimension L of the order of 15 mm according to the Z axis.
  • the protective casing has a thickness W of 0.5 mm.
  • the present invention thus makes it possible to obtain an assembly for the propagation of resistant and reliable waves at a particularly economical cost.
  • This assembly can be integrated into on-board electronics systems or in data processing centers to replace existing data transmission cables such as copper or fiber optic cables.
