Definitions

  • the invention relates to a dielectric antenna according to the preamble of claim 1.
  • the excitation distance determines the main lobe distance reached and thus the overlap level of neighboring main lobes.
  • the minimum excitation distance is given by the necessary aperture size of the individual radiators, which is required to generate a suitable illumination characteristic. However, this usually leads to an insufficient overlap level.
  • Dielectric antennas with correspondingly suitable radiation properties are known from DE 22 60 648. However, the constructive form of the antennas shown there is too complex.
  • DE 38 29 370 The same applies to DE 38 29 370.
  • the solution described there requires a very complex mechanical construction. Furthermore, the radiation properties deteriorate due to the pathogen penetration. Therefore, the principle of the invention in DE 38 29 370 cannot be used for more than two radiators.
  • the object on which the invention is based, to arrange an antenna with suitable bundling properties so closely adjacent as an exciter in a mirror antenna that a sufficiently high overlap level is achieved is achieved by the invention characterized in the main claim.
  • Part of this body is a transition area 1 with a length of (0.6 ... 0.8) ⁇ Lep.
  • the body is fed by a dielectric filled waveguide 2 with a diameter of (0.7 ... 1) ⁇ Lep.
  • a cross-sectional jump 3 of the body is a cross-sectional jump 3 of the body to (1.1 ... 1.4) ⁇ Lep.
  • the transition to the largest transverse dimension D of the emitter takes place here, depending on the diameter difference, either abruptly, stepwise or conically.
  • excellent radiation properties can be achieved with the dimensioning described.
  • the directional diagrams measured in the X-band are one Emitter of polystyrene reproduced (Fig. 2 and 3).
  • FIGS. 4 and 5 show the directional diagrams of this radiator for the case where the diameter at the radiator end 4 (FIG. 1) has been reduced by 0.3 ⁇ Lep over a length of 0.1 ⁇ Lep. This measure results in an even lower side lobe level and leads to a further improvement in the diagram symmetry.
