Definitions

  • Each elementary cell of the transmitting network is capable of introducing a phase shift to the incident wave emitted by the primary source (s) in order to compensate for each difference in the path of the radiation emitted between the primary source (s) and the transmitting network.
  • planar antenna is meant an electrically conductive flat surface (conventionally metallic) capable of emitting / receiving electromagnetic radiation.
  • An example of a planar antenna is the microstrip disc (“ patch ”).
  • elementary cell architectures can also be used, such as multilayer structures based on the concept of frequency selective surfaces, or on the concept of Fabry-Perot cavities. Radiant elements such as dipoles, slots etc. can also be used at the elementary cell level.
  • an elementary cell of a transmitting network can operate in reception or in transmission, that is to say that the first antenna of the elementary cell can also be a transmission antenna, while the second antenna of the elementary cell can also be a reception antenna.
  • Such an antenna with a transmitter array has a thickness, defined by the distance (called the “focal length”) between the radiating source and the electromagnetic lens.
  • the various electromagnetic and geometric parameters e.g. the typology of the radiating elements of the phase-shifting cells and of the emissive zone, the surface of the electromagnetic lens, the focal length, etc.
  • the parameter D -and therefore the parameter F- must be doubled to obtain a gain of 6 dBi (isotropic decibel) and maintain the same relative bandwidth at 1 dB or 3 dB.
  • the F / D ratio is typically between 0.3 and 0.7. If one wishes to maintain the F / D ratio, it is then necessary to increase F.
  • Such an antenna of the state of the art is not entirely satisfactory insofar as the search for a high gain for the antenna will therefore lead to increasing the focal length, and thereby the thickness of the l. 'antenna.
  • the search for a strong gain, while maintaining the same relative frequency behavior, will therefore require good control of the excitation of the phase-shifting cells over a large aperture.
  • controlling the excitation of phase-shifting cells over a wide aperture can prove to be a complex task, in particular when the operating frequency of the antenna is of the order of ten / hundred GHz or THz, and this because of a need for great precision in the assembly between the emissive zone and the electromagnetic lens.
  • control electronics of the switches must be positioned with care so as to disturb the radiation transmitted by the phase-shifting cells to a minimum.
  • such an antenna according to the invention makes it possible to facilitate the excitation of the phase-shifting cells over a wide aperture, when a high antenna gain is desired, by virtue of such an electromagnetic coupling zone which allows excitation of the phase-shifting cells in near field.
  • the size and shape of the resonant cavity can be adapted to optimize the radiation received by the phase-shifting cells, for example to homogenize the amplitude and the phase and to increase the coupling efficiency.
  • an electromagnetic coupling then makes it possible in particular to obtain an antenna with a reduced thickness compared to a slot antenna, to avoid a significant decrease in the electromagnetic field received by the phase-shifting cells located on the edges of the electromagnetic lens. , or to be freed from a dependence (in frequency) of the electromagnetic radiation received by the phase-shifting cells during beam depointing.
  • such a resonant cavity makes it possible not to lose energy on the lateral parts of the antenna, which makes it possible to increase the quality of the radiation transmitted by the phase-shifting cells located on the edges of the electromagnetic lens, and to increase the quality of the radiation transmitted by the phase-shifting cells located on the edges of the electromagnetic lens.
  • control the law of illumination of the electromagnetic lens (apodization or " aperture taper " in English).
  • the set of electrically conductive elements forming a contour of the resonant cavity, allows electromagnetic shielding in the vicinity of the side portions of the transmitter array antenna.
  • the set of electrically conductive elements comprises first tracks electrically connected to the polarization lines, makes it possible to consider deporting the control electronics of the switches (for example under the antenna) so as to interfere with the minimum the radiation emitted by the radiating source (s), and the radiation transmitted by the phase-shifting cells.
  • the antenna according to the invention can include one or more of the following characteristics.
  • the electromagnetic coupling zone extends in a dielectric medium.
  • the dielectric medium can be air.
  • the electromagnetic coupling zone comprises a dielectric substrate, comprising interconnection levels; the first tracks being formed on the interconnection levels; and the set of electrically conductive elements includes first vias, arranged to electrically connect the first tracks between the interconnection levels.
  • an advantage obtained is to envisage an integration of the resonant cavity within the dielectric substrate.
  • the set of electrically conductive elements comprises second tracks electrically connected to the bias lines.
  • the second tracks are formed on the interconnection levels; and the set of electrically conductive elements includes second vias, arranged to electrically connect the second tracks between the interconnection levels.
  • the antenna comprises switching means configured to switch between the first and second tracks, the first or second unswitched tracks being at floating electric potential.
  • floating electric potential is understood to mean that the unswitched tracks are not subjected to a reference electric potential at the operating frequency of the antenna.
  • an advantage obtained is to add a degree of freedom to adjust the electromagnetic behavior of the resonant cavity. More precisely, there is a first resonant cavity, the outline of which is formed by the first tracks and the first interconnection holes. Likewise, there is a second resonant cavity, the outline of which is formed by the second tracks and the second interconnection holes.
  • the switching means therefore make it possible to switch between the first resonant cavity and the second resonant cavity.
  • the first resonant cavity can be configured (size, shape) to widen the passband, while the second resonant cavity can be configured (size, shape) to increase the depointing range.
  • the set of electrically conductive elements is arranged so that the contour of the resonant cavity has an increasing cross section from the emissive zone towards the electromagnetic lens.
  • an advantage provided by such a shape of the resonant cavity is to promote a large gain for the antenna.
  • the set of electrically conductive elements is arranged so that the contour of the resonant cavity has axial symmetry.
  • axial symmetry is meant a symmetry along an axis corresponding to the normal to a plane defined by the electromagnetic lens.
  • an advantage provided by such a shape of the resonant cavity is to promote the directivity of the antenna, that is to say the ability of the antenna to concentrate the energy radiated in a solid angle or in a direction specific.
  • the emissive zone is planar.
  • an advantage obtained is to allow monolithic integration of the emissive zone into the resonant cavity when the resonant cavity is formed in a dielectric substrate.
  • the electromagnetic lens is planar.
  • an advantage obtained is to allow monolithic integration of the electromagnetic lens into the resonant cavity when the resonant cavity is formed in a dielectric substrate.
