Definitions

  • the invention relates to a microwave rotating joint device.
  • the telecommunications antennas via relay satellite, must have very large orientation capacities, typically: 0 ⁇ ⁇ ⁇ 120 ° (elevation) 0 ⁇ ⁇ ⁇ 360 ° (azimuth)
  • the complete microwave transponder is located behind the antenna.
  • thermal control is very difficult to achieve; it significantly affects the satellite's power consumption budget.
  • the invention makes it possible to integrate the electronic transmission and reception equipment on the satellite platform, thanks to the use of a new microwave rotating joint device.
  • Rotary joint devices generally use the properties of symmetry of revolution of coaxial or cylindrical propagation modes. Therefore, they require the use of transitions between the access guides (inlets / outlets) operating according to a certain type of propagation (rectangular, cylindrical guides) and the rotating joint itself.
  • the adaptation conditions mean that the band of use does not then exceed a ratio of approximately 1.5.
  • the device of the invention does not have such frequency limitation.
  • US-A 3668567 describes a dual mode rotary microwave coupler which comprises a main circular guide consisting of two parts located in the extension of one another and movable in rotation one by relation to each other around their axis of symmetry, each of these two parts being provided with two accesses orthogonal to each other and orthogonal with the wall of the guide, and a hybrid input coupler having its two outputs coupled to the two accesses of the first part by means of two guides.
  • the invention provides a device in which low-pass filters are interposed between the hybrid couplers and the accesses to the two parts of the main guide, at these accesses, and in which two cut-off guides are arranged on either side of the main guide, each of these guides being provided with two accesses which are orthogonal to it and which are orthogonal to one another, an input hydride coupler having two outputs coupled to the accesses of the first of these guides, and an output hybrid coupler having its inputs coupled to the ports of the second of these guides, this first and this second guides being guides closed at their free ends.
  • the device of the invention comprises a main circular guide consisting of two parts 10 and 11 located in the extension of one another, and movable in rotation relative to each other about their axis of symmetry ⁇ .
  • Two accesses 12 and 13 to the first part 10 of the main guide are orthogonal thereto and orthogonal to each other. They are coupled to the outputs 14 and 15 of a first hybrid coupler 18 of 3dB coupling value via two guides 16 and 17. This coupler 18 is connected at the input to two guides 19 and 20.
  • These two accesses 12 and 13 are located at a distance d1 from a short-circuit plane 21 produced by a cut-off guide.
  • Two accesses 22 and 23 to the second part 11 of the main guide are orthogonal thereto and orthogonal to each other. They are connected to the inputs 24 and 25 of a second hybrid coupler 26 of 3dB coupling value via two guides 27 and 28. This coupler 26 is connected at the output to two guides 29 and 30.
  • These two accesses 22 and 23 are located at a distance d2 from a short-circuit plane 31 produced by a cut-off guide.
  • the short-circuit plane 21 is located at a distance d1 from the two accesses 12 and 13 such that all the energy propagates in the main guide from the first part 10 to the second part 11.
  • the short-circuit 31 is located at a distance d2 from the two slots 22 and 23 such that all of this energy which comes from the slots 12 and 13 propagates in the guides 27 and 28.
  • the guides which make the connection between the hybrid couplers 18 and 26 and the main guide 10, 11 are rectangular guides.
  • One of the two inputs of the hybribe coupler 18, numbered 19, receives a signal which is transmitted to the two guides 16 and 17 and which, by coupling with the main guide via the two ports 12 and 13, allows transmission in this one of a wave with circular polarization.
  • two main guides 35 and 36 are used on either side of the main guide 10, 11, shown in FIG. 1.
  • two accesses 37 and 38 to the guide 35 are orthogonal thereto and orthogonal to each other.
  • a hybrid coupler 39 connected at the input to two guides 40 and 41, has its two outputs connected to two guides 42 and 43 which are coupled to these two ports 37 and 38.
  • a hybrid coupler 45 connected at the output to two guides 46 and 47, has its two inputs connected to two guides 48 and 49 which are coupled to two ports 50 and 51 of the guide 36, these two ports being orthogonal to this guide 36 and orthogonal to each other.
  • the two cut-off guides 35 and 36 have their free ends 58 and 59 closed and located at a distance from the planes of the accesses 37, 38, and 50, 51 such that all the energy is transmitted from one part of the coupler 39, via ports 37 and 38, to the junction, then from the junction to coupler 45, via ports 50 and 51.
  • the excitation of the circular polarization wave of the main guide 10, 11 is done without obstacle in this main guide; it follows that if four filters 54, 55 and 56, 57 of the low-pass type are placed which bring a short-circuit plane into the plane of the accesses 12, 13 and 22, 23, the device can be used for another frequency band such that it can propagate within a diameter of the guide less than the diameter in the fictitious short-circuit planes 21 and 31 which are obtained by cut-off guides. For use at higher frequencies, the diameter of the guides 35 and 36 must therefore be less than the diameter of the guide when cut.
  • the low-pass filters 54 and 55 have short-circuit planes in the planes of the accesses 12 and 13, it is therefore possible to operate with a second frequency band.
  • each hybrid input coupler 18, 39 which corresponds respectively to a single output from each hybrid output coupler 26, 45 .
  • each hybric coupler of input its second input to convey a second signal at the same frequency as that conveyed by the first input.
  • the electrical contact between the two parts 10 and 11 of the central conductor can be made using a coupling device shown in FIG. 4.
  • the electrical junction in the P plane occurs at the bottom of a corrugation.
  • Such a type of junction makes it possible to obtain good electrical continuity without requiring very good mechanical contact.
  • this circular polarized wave can be done using a single access 22 (or 23) after having placed a polarizing device in the second part 11 of the main guide.
