Definitions

  • the present invention relates generally to a radiating element device, such as antenna, as well than a method of manufacturing such a device.
  • the antenna is for example intended to be integrated into a satellite.
  • the supporting structure is made of a fiber material of carbon which is metallized on its surface.
  • This structure carrier defines a plurality of elementary cells closed matrically arranged like a “nest bees. "Electronic circuits are arranged at inside these cells.
  • the supporting structure supports an antenna body on which radiating elements are attached. Each radiating element radiates in response to receiving an output signal produced by an electronic circuit.
  • the lower surface of the supporting structure defines a bottom supporting conductive connecting elements suitable for applying input signals to electronic circuits.
  • the antenna described in this technical document anterior has the main disadvantage of a structure complex that requires many manufacturing steps.
  • a first objective of the invention is to provide a device for radiant elements whose structure is considerably simplified compared to the prior art.
  • a another object of the invention is to provide a method of manufacture of such a device, the method not comprising a reduced number of steps compared to the technique anterior.
  • the constitution of the device is considerably simplified in that it does not understand including an antenna body to support the elements radiant.
  • the connecting means comprise point-to-point contact means distributed over a second face of said module which is opposite to said first face and on a support, of the printed circuit type, on which is added the supporting structure.
  • resin can be used to keep the module inside the cell.
  • a method of manufacturing a device provides that at least one module is introduced electronic, on the first side of which is arranged a radiating element, in a respective cell of a supporting structure including a plurality of cells elementary, and we report the second side of the module bearing first means of contact on the support bearing second contact means so as to establish point-to-point contacts between said first and second means of contact.
  • each module 1 includes at least one circuit microwave electronics embedded in a material dielectric and together forming a block.
  • a module 1 comprises a plurality of stacked elementary structures forming a block coated in a dielectric material.
  • Each structure elementary includes a lower dielectric layer on an upper surface of which is arranged a circuit integrated, and an upper dielectric layer covering the circuit.
  • a connection to connect a first circuit integrated mounted on a dielectric layer of a first structure among the plurality of structures at a second integrated circuit mounted on a dielectric layer of a second structure among the plurality of structures is consisting of (a) - an input coplanar line arranged on the upper surface of the dielectric layer lower of the first structure, (b) - a line coplanar outlet arranged on the upper surface of the lower dielectric layer of the second structure, and (c) - a coplanar connecting line connecting a end of the input coplanar line and one end of the output coplanar line.
  • a link between the exit (or entry) of one or the single electronic circuit in module 1 and one element radiating 2 is provided for example by a microstrip line (not shown).
  • the radiating element 2 is arranged directly on the first side of this module, on the surface of the coating dielectric material, and is fixed by example by gluing on this face of the module. So the manufacturing of the antenna uses elementary modules each carrying a radiating element on one of its faces 2.
  • the antenna uses a supporting structure 4 defining a plurality of cells through hole elementaries 40, 41, 42, 43, 44, 45, 46, 47, and 48 inside at least one of which cells an electronic module 1 and its element are introduced associated radiant 2.
  • the supporting structure is for example in Magnesium and advantageously has the function of ensuring that both a function of heat dissipation and electromagnetic shielding between modules 1 which are introduced into neighboring cells.
  • Elementary cells 40-48 are arranged matrix like a "honeycomb", each cell being delimited by four walls of the structure carrier 4 and taking a general shape of a parallelepiped.
  • each module 1, carrying a radiating element 2 on one of these faces, is introduced into a cell respective of the supporting structure 4. If the module has a volume lower than the volume of the cell in which it is introduced, a resin, typically made of material dielectric, 10 is introduced into the volume of the cell 40-48 not occupied by module 1, to keep the module at inside cell 40-48. It can nevertheless be planned to machine each module 1 so that its volume coincides with that of a cell. In this case, no resin addition is not required.
  • Each module 1 relates to a face opposite the face on which the radiating element 2 is arranged, elements contact 11, 12 and 13.
  • Electronic circuits, typically microwave, included in a module 1 receive low frequency LF power signals as well as useful high frequency HF signals.
  • the supply of HF signals to an electronic circuit in a module 1 is carried out for example by means of lines coplanar, metallized vias, microstrip lines, etc ... while the LF signal supply of such circuit is carried out by means of a wire connection.
  • the antenna also includes a support, of the type printed circuit, 3 on a main surface of which protrude from the ends, or points of contact, 31-33 intended to be put in contact with the contact points protruding correspondents 11-13 of module 1.
  • the points of protruding contact on the main surface of the support are coplanar line ends, wire connection connected to signal generation sources, such as power signal or HF signal.
  • the supporting structure 4 is reported, in cells 40-48 of which were previously introduced the modules 1, on the support 3 carrying the contact points 31-33 so as to establish contacts point by point respectively between the contact points 11-13 and contact points 31-33.
