Definitions

  • the present invention relates to a power distributor device in a waveguide operating in linear polarization.
  • This device allows a distribution of power between several radial channels from a guide, of circular shape for example, supplied with linear polarization.
  • the first appointees generally have the disadvantage of large dimensions while the second appointees present problems of adaptation and isolation between channels. Dimensions criteria generally limit the use of such devices to relatively strong coupling levels (> 10 dB).
  • the object of the invention is to overcome these drawbacks by means of a very compact device allowing all ranges of coupling.
  • the present invention proposes for this purpose a power distributor device in a first circular waveguide operating in linear polarization fed by a wave, of wavelength ⁇ g, in fundamental mode, characterized in that it comprises at its end a second circular guide at the cut-off forming a short-circuit plane with the first guide, and in that it comprises two slots arranged at the periphery of the first guide parallel to the axis of this first guide, at an angle 90 ° in a mean plane perpendicular to this axis at a determined distance from the short-circuit plane so that the energy coupled in the slots is maximum, the radial direction of one of these slots forming an angle determined by relative to the plane of polarization of the incident wave in the mean plane perpendicular to these two slits, and at least one secondary slit parallel to the first two, arranged at a distance k ⁇ g 2 , k being an integer greater than or equal to one; from the mean plane perpendicular to the first two slits such that its radi
  • This arrangement makes it possible to obtain significant deviations in the coupling levels between channels and to offer space-saving offers. reduces a significant number of coupled channels.
  • the present invention provides a device in which low-pass filters are arranged at each radial slot so as to bring a short-circuit plane at each of these slots for frequencies greater than a determined frequency band, and in which the second guide is also provided at its end with a cut-off guide of smaller diameter, and two radial slots of perpendicular directions arranged at the periphery of the second guide at a determined distance from the short-circuit plane between the first and the second guide.
  • this device is a device in which in that the second guide comprises at least one secondary radial slot (47) disposed at k ⁇ g 2 , k being an integer greater than or equal to one, of the mean plane perpendicular to the first two slits.
  • This arrangement advantageously makes it possible to transmit several frequency bands.
  • the device of the invention comprises a main waveguide 10, of circular shape for example, which extends to a end by a guide 11 of the same shape, but of smaller diameter.
  • Two access guides 12, 13 orthogonal to the main guide 10 and orthogonal to each other are coupled to this main guide 10 by two resonant slots 14, 15 situated in the same transverse mean plane at a determined distance 1 from the plane 18 formed by the connection the main guide 10 and guide 11.
  • a secondary access guide 16 is arranged perpendicular and radially to the main guide 10 at a distance ⁇ g 2 in the mean plane perpendicular to the slots 14 and 15.
  • This access guide 16 is coupled to this main guide 10 by a resonant slot 17.
  • a wave linearly polarized according to the fundamental world of wavelength ⁇ g propagates in the main guide 10 from its free end 26.
  • the resonant slot 17 shown in FIG. 1, or the slots 23, 24, 25 represented in FIG. 2 ensure the coupling of the components of the wave which are respectively parallel to them, that is to say the components which correspond to the projection of the main polarization according to angles ⁇ i, each angle ⁇ i being the angular position of each slot relative to this polarization.
  • junction plane 18 of the main guide 10 and of the guide 11 forms a short-circuit plane, produced by this guide 11 at the cut-off for the fundamental mode in the frequency band considered.
  • the slots 14 and 15 have an angular deviation of 90 ° in order to capture all the incident energy.
  • the two slots 14 and 15 are arranged at a distance 1 from the short-circuit plane such that the energy coupled into these slots is maximum.
  • the direction of one of these two slots forms a determined angle with respect to the plane of polarization of the incident wave in the mean plane perpendicular to these two slots, so as to fix the power distribution between these two slots.
  • the secondary coupling slots distributed over the main guide 10 are located at a suitable distance (modulo ⁇ g / 2) from a short-circuit plane for the fundamental mode in the frequency band considered.
  • the angular positions of these slots with respect to the direction of polarization of the wave therefore define the expected coupling values.
  • FIGS. 3 and 4 the component 30 of the polarization of the incident wave 31 perpendicular to the plane of the slot 17 is transmitted, on the other hand, the component 32 parallel to this plane is not, it is coupled, for example at 3 dB, in this slot 17;
  • FIG. 3 representing a cross section of the device of the invention in a plane perpendicular to the slot 17, with a schematic representation of the direction of polarization 31 of the incident wave and that of its two orthogonal components 30 and 32 considered before coupling in the slot 17, and Figure 4 showing the same data 30 ⁇ , 31 ⁇ , 32 ⁇ after coupling.
  • the angle of the polarization of the incident wave ⁇ relative to the vertical varied and became an angle ⁇ after coupling in the slot 17.
  • the distributing device of the invention is not limited to a single frequency band, a low-pass filter (35, 36, 37) can be arranged, as shown in FIG. 5, at each slot coupled to the first main guide. ) which brings a short-circuit plane to the level of the corresponding slot (14, 15, 17) for the frequencies higher than the frequency band to be extracted.
  • the second guide 11 at the cut-off may also be provided with several slots, for example three in number (44, 45, 47) as in FIG. 1, at its periphery and coupled with it in the same way as for the first main guide, a third guide 50 at the cutoff being arranged at the end of this second guide.
  • Low-pass filters making it possible to select a frequency band greater than the first, can likewise be placed at the level of these three slots 44, 45 and 47.
