Definitions

  • the field of the invention is that of embedded network antennas, for example on satellites, reflector array antennas type (still commonly referred to as “reflectarray antennas”) or phased array antennas (or “Phased”).
  • Array Antennas are embedded network antennas, for example on satellites, reflector array antennas type (still commonly referred to as “reflectarray antennas”) or phased array antennas (or “Phased”).
  • the prior art FRA 2874749 describes a reconfigurable reflector array antenna.
  • the term "reflecting array antenna” is understood to mean an antenna comprising radiating elements, also called phase-shifting cells, defining a reflective network and charged to intercept with minimal losses of the waves comprising signals to be transmitted, delivered by a primary source, in order to reflect them in a chosen direction, called the pointing direction.
  • phase-shifting cell provides it with phase control devices.
  • phase controls can be achieved by providing the radiating elements with controllable components (diodes, MEMS); this is called an active reflector network, or by modifying the physical form of the radiating element; we then speak of a passive reflector network.
  • MEMS controllable components
  • the active reflector network makes it possible to realize reconfigurable covers at the cost of a significant complexity, the passive reflector network is mainly attractive for its simple planar geometry.
  • each reflector array consists of a set comprising a support with reflector patterns generally etched, a spacer and a ground plane, although the latter two elements are not not specific to the cover, the spacer may typically be a honeycomb structure.
  • the present invention proposes a device for storing the radiating networks in a compact volume and in particular for storing the substrates carrying the radiating patterns in means that can be easily deployed in space. It thus allows the implementation of a large number of radiating networks under a footprint and under a reduced mass compared to a concept using as many radiant networks constituted by rigid panels and the interchangeability in flight of the covers of an antenna. changing as needed the radiating network.
  • the reconfigurable network antenna comprises a source capable of delivering signals in the form of a wave, the loading and placement means making it possible to selectively position a subset of radiating patterns opposite the source. .
  • the reconfigurable network antenna comprises a beam forming distributor supplying the radiating elements so as to constitute a direct radiation type antenna.
  • the radiating patterns may be coupled to controllable phase control devices which may be of the diode or MEMS type.
  • the scrolling system of the radiating pattern film comprises a first motorized drum and a second drum with a permanent return moment.
  • the radiating networks further comprise a ground plane and a spacer.
  • the scrolling system further comprises spacing rollers, fixed on a ground plane and permitting the scrolling of the patterning film radiating at a fixed distance from said ground plane so as to impose a space between said film and said ground plane.
  • the film is thus storable by winding. It is then sufficient to position it by unwinding in front of a single ground plane so that it is operational, allowing to put in relation to the source a selected radiating network.
  • the film is positioned on a support whose distance to the carrier film of the radiating patterns can be adjusted.
  • the first film comprises, on one and the same face, first constituent parts of the radiating patterns and second constituent parts of the ground plans.
  • An adequate unwinding operation makes it possible to match a first film portion and a second portion so as to constitute the following assembly: radiating patterns / spacer constituted by the air / a ground plane.
  • the first film has on one of its faces, the radiating patterns and on the other side the ground plane.
  • the antenna comprises: a motorized drum, an armature and means for deploying said film on the surface of the armature.
  • the deployment means comprise a reel of the film, and a cable for pulling the film from the reel, said cable being driven by a drum.
  • the deployment means comprise pulleys for scrolling said film.
  • the reconfigurable network antenna further comprises means for scrolling a second film.
  • the antenna further comprises an armature having a first face and a second face and deployment means of the first film on said first face and the second film on said second face so as to position against a selected area of said first film and a selected area of said second film.
  • the deployment means of said films comprise a first reel of the first film, a second reel of the second film and two cables for drawing said films, said cables being driven by a drum.
  • the deployment means comprise pulleys for scrolling said films.
  • the antenna comprises a sensor for reading position information etched on an edge of the first and / or second film.
  • the reconfigurable network antenna comprises a set of frames for deploying in parallel and in the same plane, several films comprising sub-sets of radiating patterns for selectively positioning a subset of patterns. radiating opposite the source.
  • the reconfigurable reflector array antenna of the invention can be embedded on a geostationary telecommunication satellite in Ku-band (12 to 18 GHz). But, the invention is not limited to this application. It concerns in fact radar antennas embedded on satellites, flying possibly in formation, or on airplanes or spacecraft, such as shuttles. Thus, the invention is well suited to SAR antennas [synthetic aperture radar, C-band (4 to 8 GHz) or X-band (8 to 12 GHz)].
  • the array antenna is a reflector array antenna type antenna and comprises a support structure SS adapted to be secured to a satellite (not shown) and on which is all d first fixed, in a chosen location, a primary source S responsible for delivering at a selected solid angle DPS main direction, called pointing direction of the source, waves comprising signals to be transmitted.
  • the source is for example made in the form of a horn, the radiating elements are reflective elements capable of reflecting the waves comprising the signals to be transmitted.
  • the antenna also comprises a system for deploying a film F 1 carrying different subsets reflective patterns constituting the reflector networks, with respect to a fixed ground plane by maintaining a spacer between said reflector gratings and the ground plane.
  • the solution is to arrange the networks each comprising a set of reflective patterns, one after the other on a thin film. More precisely, the film is wound on two drums T 1 and T 2 . By the rotation of the drums, the film passes in front of a mass plane PM from which it is separated by a constant distance maintained by two spacer rollers re 1 and re 2 positioned relative to the ground plane.
  • the space E (in this case the space) between the film and the ground plane replaces the spacer of the reflector network.
  • the film is held flat under a tension force generated by a moment acting continuously on the drum T 1 or it is wound. This moment can be generated by a torsional spring located inside the drum or any other device. Variations thermo-elastic type are thus compensated permanently which allows a maintenance of the flatness of the substrate.
  • the change of the subset of reflective patterns is obtained by winding the film on the drum T 2 until the desired pattern is positioned in front of the ground plane and in front of the source.
  • a motorization on the drum T 2 associated with a position sensor allows the positioning and its control.
  • These functions can be obtained by a stepper motor and a gearbox for example gearing, located in the drum T 2 associated with a sensor reading position information etched on an edge of the film or any other device for these functions.
  • the film scrolls in one direction or the other and is kept wound on the two drums by the action of the permanent moment acting on the drum T 1 .
  • the movements of the reel and the drum can also be obtained by a common motor (gear drive notched pulley for example), in this case a torsion spring must make the connection between the outer portion of the reel and its axis to ensure the permanent moment whatever the state of winding of the film.
  • the film comprises a reflector network RRi highlighted in figure 1b and positioned selectively opposite the source, (whereas the neighboring networks RR i-1 and RR i + 1 are represented as not being operational), each reflector network comprises several phase-shifting cells capable of imposing on the waves (delivered by the source) a phase shift with a selected frequency phase dispersion, in order to reflect them in a chosen direction.
  • the chosen phase shift and / or phase dispersion in frequency chosen varies (s) from a reflector network RRi to another, so that the coverage area (or "spot") of the beam of the antenna, and / or the shape of this zone, vary according to the selected RRi reflector network.
  • the moving assembly must be immobilized by a known type of stacking device.
  • the low mass and low bulk of the carrier film reflector patterns wound on the drums provides an antenna with a large number of covers in a compact package.
  • the ground plane is unique for all covers which avoids accumulated carriage and the spacer is replaced by vacuum which favors the RF performance of the reflector array antenna.
  • the first film may carry the ground plane and the antenna may advantageously comprise a single motorized drum associated with the antenna.
  • the Figures 2a and 2b schematically illustrate this configuration example.
  • the figure 2a illustrates a top view of the armature Ar comprising a set of pulleys P or1 , P or2 , P or3 , on which, thanks to a cable C 1 , a single film carrying the array of reflectors / spacer / ground plane F 1 + MP is deployed from a reel D 1 .
  • the figure 2b illustrates a sectional view highlighting the scrolling system of the film having on its upper face the reflector patterns and on its underside the ground plane on the armature. The film from the reel D 1 is pulled via the cable C 1 by the motorized drum T 3 , the cable and the film thus being driven over the pulleys.
  • the antenna comprises both a first film F 1 comprising the subsets of reflector patterns stored on a first reel D 1 and a second film F 2 constituting the ground plane stored on a second reel D 2 .
  • the Figures 3a and 3b illustrate this variant in which a single drum T 3 can advantageously be used to deploy simultaneously the two films with a single engine associated with a set of two cables C 1 and C 2 and references by three pulleys Pou 1 , Pou 2 , Pou 3 .
  • the figure 4a illustrates a top view of an antenna according to the invention on board a Sat satellite and shown in the deployed position, highlighting three armatures Ar 1 , Ar 2 , Ar 3 , coupled to three reels D 11 , D 12 , D 13 , the reflector gratings being on non-rolled films F 11, F 12 , F 13 .
  • the frames are deployed from a stacking element G, the position of the source S being adjustable to be incident on a selected reflector panel.
  • the figure 4b illustrates this same antenna sectional view and highlighting the armature Ar 2 .
  • RF performance is further enhanced by the provision of an empty gap which is a spacer for excellent dielectric performance.
  • the films consist of a dielectric material, whether or not reinforced with metal etchings, or in a material which reflects electromagnetic waves of thin thickness.
  • these materials are for example of the ARLON, KAPTON, ROGERS or CUCLAD type consisting of a film with a thin thickness of 50 or 127 micrometers.
  • the flexibility of these films makes it possible to obtain, in association with the voltage maintaining devices, the required planieties which are for example of the order of 200 micrometers RMS for a Ku-band reflector network of 1mx1m.
  • the invention has previously been described in the case of a reflector array antenna but is equally applicable to antennas of the direct radiation network type.
  • the distribution of the signal to the radiating elements is no longer done using an illumination source. It is done using a beamforming splitter (also called Beam Forming Network) with access input and as many access outputs as elements Radiant.
  • the distribution network is preferably waveguide type, to reduce distribution losses. In the case where the radiating elements are small, it may be judicious to adopt a hybrid approach for the distribution network, combining a waveguide type technology for long-distance routing, and a planar technology to proximity of the radiating elements to benefit from its compactness.
  • the radiating elements are planar technology type. They include a ground plane, an excitation mode (opening in the ground plane, coupling power supply, probe supply), and one or more planar patterns (patches, see grid type etching).
  • the radiating elements are potentially equipped with lateral cavities, which increases the decoupling between radiating elements and can help in their development.
  • the reconfiguration of the diagram is effected by modifying the phase of the signal radiated by the radiating elements.
  • the way to proceed may be to change the form.
  • the networks can be made on two films.
  • the figure 5 illustrates such a configuration highlighting two films F 1 and F 1 , carrying the reflective patterns.
  • Drums T 1 , T 1 ', T 2 , T 2 allow to ensure the scrolling of said films.
  • the desired spacings are calibrated by means of spacer rollers re 1 , re 1 ' , re 2 , re 2' positioned relative to a support.
