Definitions

  • the invention relates to a three-plate microwave module.
  • each line in one or the other cavity is carried out using spacers, each line penetrating a cavity through a window.
  • a second line is arranged in a third plane so that the coupling opening is located between the first plane and a third plane.
  • Such a module makes it possible to avoid any contact during a change in propagation mode, for example during a triplate-coaxial-triplate transition necessary for connecting different transmission planes.
  • Such a module can be used to perform division, phase shift or distribution functions in triplate mode. It allows thus to realize generalized couplers by using elementary modules all identical.
  • Such a module can advantageously be used at the output of a slot antenna directly driven in triplate mode.
  • FIGS. 1, 2 and 3 represent a microwave module according to the invention which allows a change of plane between two triplate lines 10 and 11 with possibly, as shown in these figures, a change of direction between these lines 10 and 11.
  • the heart of this module is a set of two cavities 12 and 13 produced respectively in conductive blocks, for example metallic, 14 and 15. These cavities 12 and 13 are located one on the other and are separated from each other at using a conductive piece, for example metallic, planar 16, for example a disc, the circumference of which is associated with the assembly of two edges of the cavities 12 and 13 makes a coupling slot 17 making it possible to convey electromagnetic energy from one cavity to another. The transfer of energy therefore depends on the geometric shapes of the cavities 12 and 13 and on the coupling slot 17.
  • triplate line 10 Access to a cavity 12 (or 13) is done using a triplate line 10 (or 11).
  • the positioning of this line (10 or 11) inside the corresponding cavity is conventionally carried out at mid-height of the ground planes using spacers made of dielectric material 18 and 19 (or 20 and 21) .
  • Each triplate line (10 or 11) enters the corresponding cavity (12 or 13) through a window (22 or 23) whose geometry is dimensioned in a manner known to those skilled in the art to ensure electrical continuity and continuity of impedance.
  • the module according to the invention comprises two levels of triplate circuits; each of them being formed by two ground planes arranged on either side of a line (10, 11) which allows the transfer of energy; the central ground plane, produced by part 16, being common to the two levels.
  • the coupling opening 17 therefore allows transmission between the two lines 10 and 11 which are isolated from each other by direct current.
  • the cavities 12 and 13 are configured as shown in FIG. 2, and the module according to the invention makes it possible to transmit electromagnetic energy, conveyed by line 10 in a first plane and according to a first direction, second line 11 located in another plane, this second line 11 being directed in another direction whose projection in the first plane makes an angle ⁇ with the first direction.
  • the change of direction of propagation function in the same plane can be obtained by configuring the cavities 12 and 13 as in FIG. 4 for example.
  • the upper cavity 13 is completely closed and is filled with a spacer dielectric disc 24, for example of about 6 mm.
  • the bottom cavity 12 for its part, is provided with two access windows 22 and 23 ensuring the passage of the two lines 10 and 11.
  • the device of FIG. 5 has also been produced with eight windows: top and bottom for each access whatever the configuration of the parts. Performances in all respects similar to the configuration in FIG. 5 were measured, irreparably reflecting the versatility of the concept.
  • the geometry of the part 16 is essential because it determines the shape of the slot 17. It is therefore subject to careful optimization.
  • Figure 7 gives an example of possible shape for the part 16, here the shape of a cross, using for example the first line 10 at the lower level and the other three lines 11, 28 and 29 at the upper level. But any combination of levels provides the same functionality. In the module of the invention, therefore, we play on the shape of the part 16 (disc, cross, disc provided with notches ...) to obtain the desired operation.
  • module of the invention it is therefore possible to use the module of the invention to the maximum of its possibilities in a foreground (for example power division, hybrid junction, etc.) before using its possibilities linked to such a transition between two planes.
  • a foreground for example power division, hybrid junction, etc.
  • Such a module can be attached in one piece in composite technology by cooking.
  • the part 16 can be produced, for example, by machining, by etching, by metallic deposit, etc.
  • triplate circuits suspended, for example, by rivets using air as a dielectric.
