Definitions

  • the present invention relates to an assembly device for fixing a radome on a reflector, intended for use in concave reflector antennas having for example the shape of at least one parabola portion, the reflector being possibly equipped with a skirt.
  • Parabolic reflector antennas are usually used for mobile communication networks.
  • Such an antenna comprises a main reflector having a concavity having for example the shape of a paraboloid of revolution about the axis of symmetry of the antenna, and a feeding device located along the axis of symmetry of the antenna.
  • antenna for transmitting electromagnetic waves transmitted or received by the antenna.
  • the periphery of the parabola is most often provided with a cylindrical wall, also called skirt or screen, which limits the lateral radiation of the antenna and thus improves its performance.
  • a radome is associated with an impervious protective surface which partitions the space defined by the reflector vis-à-vis the outside.
  • This radome can be flexible or relatively rigid.
  • a radome composed of a flexible material such as a fabric has a limited production cost and a small footprint prior to installation on the antenna.
  • such a flexible radome has disadvantages related to a relative fragility and a complex system of attachment to the skirt of the antenna, requiring self-tensing elements for its setting and its maintenance under tension, such as springs.
  • a rigid but flexible radome made of a non-flexible material, the most used today, has the advantage of good resistance to the external climatic environment such as rain, wind or snow. It is therefore essential to ensure a solid attachment capable of withstanding the wind force, particularly for reflectors of large diameter.
  • the fastening system must also allow rapid disassembly / reassembly and without degradation of the radome on the reflector.
  • the rigid radome is most often fixed on the reflector by means of different devices having in common to require a plurality of screws or bolts placed on the periphery of the radome.
  • the number of bolts is high.
  • the presence of such a quantity of metal bolts and the asperities they form on the radome can cause degradation of the radio performance of the antenna.
  • a thermoforming method is usually used in the case of materials capable of withstanding a high temperature and whose thermal expansion coefficient is adapted, to give the rigid radome a lid shape having a folded flange facilitating attachment to the skirt of the reflector .
  • the document EP1762860 discloses a radar device with a flat support comprising antennas, the support being covered by two halves of a cover, the upper half acting as a radome.
  • the upper half, the flat support, and the lower half are stacked in this order, and their peripheries are in direct contact.
  • Two watertight rings are attached to the contact surfaces of the two halves of the cover with the flat support. The stack is held together by means of metal clips.
  • the document EP2772985 discloses a fixation of a flat radome of a parabolic antenna, consisting of two annular metal parts pinching the stacked peripheries of the radome and the reflector.
  • the lower annular part has grooves for better adhesion to the periphery of the reflector.
  • the technical problem that arises then is to find an assembly solution suitable for fixing a radome consisting of a rigid material such as a non-thermoformable material, for example a low density multilayer material or "honeycomb", and having a flat flange on a reflector.
  • a radome consisting of a rigid material such as a non-thermoformable material, for example a low density multilayer material or "honeycomb", and having a flat flange on a reflector.
  • the device assembly must be inexpensive and easy to implement, whether assembly or disassembly.
  • the object of the present invention is an antenna according to claim 1.
  • the half-flanges are plastic.
  • the half-flanges are made of a rigid dielectric material having nevertheless a certain flexibility, such as for example a polymer.
  • Suitable polymers include polycarbonate PC, polypropylene PP, polystyrene PS, PVC polyvinyl chloride, acrylonitrile-butadiene-styrene ABS, etc.
  • the rim is metallic.
  • the rim may be made by folding a sheet of metal, for example aluminum or stainless steel.
  • the rim is circular and its ends are connected by a clamping means.
  • the upper half-flange and the lower half-flange bear protuberances capable of cooperating with a housing formed in the flat flange. During assembly, these protuberances facilitate and improve the positioning accuracy of the half-flanges relative to the flanged element.
  • the second section of the lower half-flange comprises orifices intended to receive means for fixing the lower half-flange on the support.
  • these orifices exist, they are arranged so as to be in vis-à-vis perforations previously made in the support.
  • the present solution has the advantage of providing a device for assembling a radome on a light reflector and at low cost with high mechanical and radioelectric performance. It should be noted that the cost of the radome and its installation on the reflector is an important part of the total cost of the antenna. In addition, it can allow assemblies that could not be made using currently known devices.
  • the invention also relates to a method of assembling the antenna described above.
  • the method comprises steps according to claim 7.
  • the value of this solution is to avoid drilling many holes in the radome, as well as the corresponding manufacturing process steps and the time required. It also does not require perforations in the metal rim.
  • the solution takes advantage of the density of the material chosen for the radome to achieve a pressure assembly so as to incorporate protruding reliefs, for example in the form of teeth, in this lightweight material, solid and soft. The number of parts to make the assembly is also reduced. The step of shaping the rim replaces the steps of drilling holes, reduces the time and complexity of assembly, and therefore the associated costs.
  • the intensity of the radiation I in dB is given on the ordinate, and on the abscissa the emission / reception angle ⁇ in degrees.
  • a rigid radome is made of a light and solid but non-flexible material, such as a sandwich-type material.
  • the radome is usually made of a flexible dielectric material such as a polymer, fiberglass, etc.
  • Suitable polymers are in particular PC polycarbonate, polypropylene PP, polystyrene PS, PVC polyvinyl chloride acrylonitrile-butadiene-styrene ABS, etc.
  • the figure 1 illustrates a partial perspective view of an example of material 1 used for the realization of the rigid radome of a concave reflector antenna.
  • This material sandwich type, comprises an upper layer 2 consisting of a flat plate of polymeric material, such as polypropylene, and a lower layer 3 consisting of a plate of polymeric material which may be similar or different from that of the upper layer 2.
  • the outer layers 2, 3 must be thin (eg 0.55 mm) and have a very low dielectric constant.
  • the layers 2 and 3 surround an intermediate layer 4, formed of cells 5 of low dielectric constant (eg ⁇ r ⁇ 1).
  • the cells 5 are of substantially conical shape and filled with air.
  • Their walls are made of polymer material, such as polypropylene. Thanks to this material, the radome 1 obtained is light and strong, while maintaining a certain flexibility that prevents it from breaking under a moderate stress.
  • the means used must ensure a solid attachment capable of withstanding the force of the wind, especially for antennas of large diameter.
  • Some materials are not thermoformable, which is particularly the case of the sandwich type material illustrated by the figure 1 . It is therefore not possible to give them a shape that would easily fix the flat radome on the edge of the reflector or skirt.
  • the figure 2 illustrates, in exploded view, an embodiment of an assembly device for allowing the attachment of an element 20 having a flat flange 21 on a support.

  • the second flange 33 forms an angle ⁇ that is non-zero with the first flange 30, which may be for example approximately 90 °, thereby forming L.
