Definitions

  • the invention relates to a microwave antenna for left-and right-circularly polarized electromagnetic waves comprising a waveguide radiator and two over a 90 - driven coupler (hybrid) to 9 0 ° to one another perpendicular to the axis of the waveguide radiator disposed excitation radiators - 3 dB.
  • Such a microwave antenna which can also be used for satellite reception and is known in practice, is shown in FIG. 1.
  • Waves with left or right polarization can be generated or received by feeding (transmitting) or removing (receiving) the high-frequency energy at one of the two connecting gates of the hybrid that are decoupled from one another.
  • the other connection gate is either closed or used to receive or send the orthogonal components.
  • the quality of the circular polarization depends crucially on the fact that the two connecting lines L 1 , L 2 between the excitation radiators S designed as plugs immersed in the waveguide radiator HS via plug connector ST and the hybrid H, and the metal pins and the plug connectors are exactly the same are long.
  • the length difference in the area around 12 GHz is only about 0.1 mm if there is a deviation from the required 90 ° phase difference of max. 3 0 should be observed.
  • these high demands on the manufacturing accuracy of the cables and connectors can only be met with the aid of complicated and expensive manufacturing and assembly techniques.
  • the invention has for its object to provide a microwave antenna of the type mentioned, which has a simple and inexpensive structure, as far as possible suitable for mass production, with high accuracy of the phase difference of the polarization components.
  • This object is achieved in that the exciter radiator, the hybrid, and their connecting lines are implemented in printing technology on a substrate, the part of which supports the exciter radiator and is arranged transversely in the waveguide radiator.
  • the printed circuit is produced photographically with a single template.
  • the advantage is achieved in a simple and elegant manner that the connectors required for the known antenna and their inaccuracies are eliminated and, moreover, the connecting lines between the excitation radiators and the corresponding connections of the hybrid are practically arbitrarily precise and by a correspondingly large template are also extremely inexpensive to manufacture.
  • the circuit board is ideally suited for mass production, without fear of any deterioration or fluctuations in accuracy. Rather, with the antenna according to the invention, the deviations from the 90 ° phase difference can easily be kept below 1 °. In addition, it also has a lower damping compared to the prior art described.
  • the structure according to the invention eliminates any weather protection that may be necessary (for example by covering the radiator aperture) because the substrate arranged transversely in the waveguide radiator already provides adequate sealing against weather influences.
  • a longitudinal current-free plane is generated in this way at a distance of a quarter wavelength from the short circuit, in which the installation of the substrate does not cause any interference.
  • FIGS. 2 and 3 show an exemplary embodiment of the microwave antenna according to the invention, FIG. 2 representing an axial section and FIG. 3 a plan view of the substrate to be inserted transversely into the antenna.
  • the microwave antenna has an open circular waveguide radiator part 1 widened in a funnel shape in the radiation direction and a round waveguide radiator part 3 short-circuited at the end 2.
  • a substrate 7 is inserted between the two radiator parts 1, 3, which are firmly connected to one another by means of fastening flanges 4, 4 'or 5, 5' and screws 6, and consists of a carrier plate 8 made of insulating material coated on both sides with a metal covering, the one facing the radiator part 1 , together with the housing, the metal layer 9 forming the ground surface has a circular recess whose diameter corresponds to the inside diameter of the circular waveguide, so that the electromagnetic waves can pass through the carrier plate 8 unhindered.
  • the metal layer 10 is, apart from two antenna connection lines 11, one connected to it, made up of four ⁇ / 4-long, interconnected in a rectangular configuration interconnects 12, two further lines 13 of exactly the same length for connecting the hybrid 12 with two below 9 0 ° to each other excitation radiators 14, the equal lengths of the protruding into the radiant section 1 Endab - cutting the lines 13 are formed, and two exciter emitters 14 diametrically opposed, extending into the operating position also in the radiant section 1 short, remaining with the Ground surface lo connected metal strips 15 etched away.
  • the lines 11 and 13 are formed as 5 0 -Ohm lines in microstrip technology.
  • a channel 16 is formed between the flanges 4 and 5 for the contact-free arrangement of the connecting lines 13, the hybrid 12 and the connecting lines 11, the latter via a plug connection 17, part of which is arranged in a holder 18 further cables 19 are connected.
  • the linearly polarized wave carried in the lines 11 is converted into a circularly polarized wave that can be emitted or received by the funnel radiator.
  • the entire microwave antenna can be manufactured very precisely in terms of dimensions due to the complete structure in printing technology in an extremely simple and inexpensive manner.
  • very good adaptation and interference-free coupling at the insertion point of the substrate 7 are achieved.
