Definitions

  • the present invention relates to an illumination source for a telecommunications antenna.
  • the sources of illumination with conventional traps which have the advantage of being more economical to produce are of low directivity but sufficient to illuminate a reflector of the parabolic type. They are made up of parts with an axis of symmetry (circular guide, trap, etc.) and must be supplied by a standard rectangular waveguide. This feeding is carried out by a transition either continuous or by step.
  • a French patent application published under the number 2 096 684 describes a device for coupling a circular waveguide to a parabolic reflector of revolution which comprises a circular guide, excited according to TE11 mode, a first end of which is at the focus of this reflector, and the other end of which is connected to a rectangular waveguide.
  • An incomplete cylindrical annular cavity surrounds the first end of the guide.
  • a transition element formed of a series of waveguide sections of gradually varying shapes and dimensions, connects to the rectangular waveguide. But a continuous transition must be long to have good adaptation characteristics.
  • a step transition as described in the document cited above, makes it possible to reduce the length but is difficult to manufacture using low-cost technologies.
  • the present invention aims to overcome these drawbacks.
  • a source of illumination for telecommunication antenna comprising: - a radiating part having a circular opening; - a transition formed by gradually varying waveguide sections; - a connection flange to a rectangular guide; characterized in that said source is made of moldable material, in that the radiating part is formed by a collar provided with at least two concentric grooves forming two traps, and in that said source comprises means for fixing in a support .
  • Such a source has the great advantage of being a broadband illumination source (10.7 - 12.75 GHz) designed to illuminate an antenna reflector and this, with very high level radio performance, mechanical performance and climatic conditions that meet very severe requirements and whose industrial development calls for economic technologies.
  • the invention makes it possible, in fact, to produce, by molding, a fully integrated trap and therefore has a much lower cost compared to the sources of the prior art obtained by electroforming or EDM.
  • the source 10 according to the invention is a guide which, at its first end, has a circular opening 11, and, at its other end, has a rectangular opening 12.
  • a radiating part 13 provided with two traps 14 and 15 and the opening 11 whose diameter determines the operating frequency; a transition 16 between this part 13 and a rectangular waveguide standard space, not shown in the figure, which allows connection to a microwave head; - A flange 17, which ends this transition 16, which allows the connection to this rectangular guide.
  • This source will be described more precisely going from its first end to its second end.
  • this source 10 includes: - A cylindrical flange 21, located in a pocket location of this first end, whose axis is the axis of symmetry ⁇ of the source 10 and which is provided on its face located on the side of the first opening with two concentric circular grooves 14 and 15 which produce the two traps; - Two concentric cylindrical flanges 18 and 19 located in its middle part, whose axis is the axis of symmetry ⁇ of the source 10, these flanges being flanges for fixing the source 10 in its support; - a pressurization nozzle 20; - the connection flange 17 located at the second end of the source 10.
  • this source 10 comprises six steps 22, 23, 24, 25, 25 and 27 which are symmetrical with respect to two planes P1 and P2 of perpendicular section and the size of which decreases progressively from the circular opening 11 to reach that of the second rectangular end 12. It therefore comprises: - first two steps 22 and 23 in circular guide; - three steps 24, 25 and 26 in a rectangular guide whose corners have been rounded; - a last step 27 in rectangular guide.
  • the part 28 external to the source corresponds to the place where the material is poured between two forms used for molding.
  • this source can be produced according to a manufacturing process comprising: - The casting of a moldable material, for example an aluminum alloy, or a dielectric material such as an epoxy resin, in a mold formed of two joined shapes; - drying of this material; - demoulding.
  • a moldable material for example an aluminum alloy, or a dielectric material such as an epoxy resin
  • the moldable material is a dielectric material
  • a metallization step for example with nickel.
  • the molding tools are, for example, made of special steel. They have several moving parts, the main ones being: - two symmetrical shapes, the longitudinal junction plane of which contains the axis ⁇ of revolution of the source according to the invention; - a central nucleus whose male form faithfully reproduces the cylindrical waveguide followed by the rectilinear transition.
  • a supply system of moldable material allows the part to be filled inside the molding tools.
  • a system of movable parts for ejecting the molded part makes it possible to extract this part from the molds without deforming it, thus retaining all of its geometric characteristics.
  • the invention has the great advantage of requiring no rework in machining.
  • its radioelectric design and its manufacturing process are suitable for the medium series, even the large series, and thus make it possible to reach low price levels.
  • Such a production method also allows integration into an additional cost of a pressurization nozzle.
  • a protective radome can be fixed on the opening plane of the circular part 13: It can thus oppose the penetration of runoff water into the source. It also serves to plug the source when it is pressurized.
  • this source 10 Due to the traps 14 and 15, this source 10 has a well symmetrical radiation pattern: of the order of - 10 dB around 50 °.
  • Such a source has a very good standing wave ratio (ROS) of the order of 1.07 for frequencies varying from 10.7 to 12.75 GHz, whether made of metallized epoxy or aluminum.
  • ROS standing wave ratio
  • the invention makes it possible to obtain a very compact radiating source and directly connectable to a standard rectangular guide. It also makes it possible to produce the part by very economical technological means such as: - aluminum alloy molding; - molding of metallizable epoxy resins; - electroforming with non-destructible core; - EDM.
  • Illumination sources in accordance with the invention can be produced using mass production technologies, for example: - in precision alloy aluminum casting; - in epoxy resin molding with metallization, for example nickel.
