Definitions

  • the invention relates to a device for excitation of a waveguide in circular polarization by a planar antenna, for example printed or plated.
  • This device is a compact device for excitation of a waveguide in double circular polarization with wide band and high polarization purity. It makes it possible to generate a wave in right and / or left circular polarization in a guide with a section, for example square or circular.
  • Such a device is intended to be used in a multisource antenna with frequency reuse in circular polarization.
  • TEM Transverse Electro-magnetic
  • Document US-A-3,665,480 discloses a printed antenna associated with a waveguide.
  • the antenna has a radiating opening in the form of an annular slot formed in a conductive plate and orthogonal feed lines, arranged between two conductive plates separated by a dielectric, coming to terminate under the central disc delimited by the annular slot.
  • Such an antenna is of poor quality in terms of bandwidth and polarization purity and therefore incompatible with use in pure circular polarization on telecommunication frequency bands.
  • the object of the invention is to propose a device for excitation of a waveguide by a planar antenna having improved qualities in terms of bandwidth, ellipticity and compactness.
  • Such a device has excellent adaptation in a wide frequency band and excellent purity of circular polarization in this band.
  • the device of the invention consists of a guide 10, for example cylindrical, excited in circular polarization by an antenna 11, for example plated or printed, with a single resonator.
  • This antenna therefore includes a flat metallic pattern deposited on an insulating substrate.
  • the shape of the antenna is scalable depending on the performance to be expected (typically square or circular depending on the shape of the waveguide).
  • the bottom of the waveguide 12 serves as a ground plane for the antenna, here in the form of a disc.
  • the antenna is supplied by two coaxial attacks 13 and 14 adapted and situated at 90 ° from one another relative to the center of the guide, these two attacks being isolated from each other using a dielectric 18.
  • Each coaxial attack is supplied in phase quadrature by a 90 ° hybrid coupler (15) which can be a hybrid coupler with branches for example.
  • An access 16 of this hybrid coupler 15 generates right circular polarization; the other access 17 generates left circular polarization.
  • This hybrid coupler 15 is unbalanced in amplitude so as to compensate for the couplings between probes and to generate in each polarization a field having a minimum ellipticity ratio.
  • the antenna for example plated or printed, is constituted by a double resonator 11, 20, which makes it possible to increase the bandwidth of the device.
  • the two parts 11 and 20 of this double resonator having here, for example, the form of two concentric metal discs, are spaced apart by means of a dielectric 21.
  • the antenna 11 (with a double resonator or with a single resonator), for example plated or printed, is supplied by four coaxial attacks 22, 23, 24 and 25 supplied with quadrature (0 °, ⁇ 90 °, ⁇ 180 °, ⁇ 270 °) by a device 26 composed of a hybrid coupler and two "mousetraps"("Rat-race in English or rings hybrids) or a hybrid coupler and two suitable "tees". Each hybrid coupler and each "mousetrap" or “tee” is balanced (3dB coupler) and thus generates pure circular polarization waves in the waveguide.
  • the hybrid coupler produces the phase quadrature necessary for circular polarization.
  • the "mousetraps” or “tees”, constituting in fact a balun device, can, moreover, be replaced by other types of “balun” (balance unit "in English) or balancing systems.
  • the device of the invention can include a resonator (figure 1,2), two resonators (figure 3), but it can also include more than two resonators: three, four ...
  • these resonators are not necessarily circular in shape: they can have any shape: circular, square, cross, star, hexagonal, or have notches or asymmetrical accidents. They may also have recesses (surfaces unmetallized) of any shape within their outline.
  • dielectric layers (18, 21) for supporting these resonators (11, 20) can be partially or totally replaced by other types of supports (spacers, columns) of any material (conductor or insulator) known to man. art.
  • these resonators can be extended out of their plane or in their plane by metal parts which may or may not come into electrical contact with the wall of the guide.
  • the guides used can be circular, square, but also hexagonal, polygonal, elliptical or other. They can present accidents such as excess thickness or furrows in the longitudinal, oblique or transverse direction, or present local accidents such as pawns, iris, slots. They can also be globally or locally flared or narrowed, or both successively, according to a determined law for example.
  • the excitation system can just as easily be located inside the guide.
  • the device of the invention can be powered by 2, by 4 but also by a greater number of accesses, which can be connected to the first resonator (11), but also to the other resonators (20 ).
