Definitions

  • the invention relates to a planar antenna according to the Preamble of claim 1.
  • the currently known antenna systems for the Reception of satellite signals, especially TV, Astra and DSR signals within the DBS band (Direct Broadcasting Satellite) from 11.70 Ghz to 12.50 Ghz for electronic means of communication are based on the electromagnetic excitation of dipole groups that are fed to each other in certain phases and thus linearly or circularly polarized Generate radiation fields.
  • Such planar antennas are mostly in triplate technology or microstrip technology realized.
  • the planar antenna is electronics in particular a converter downstream, which the Signals processed depending on the application.
  • planar antenna and electronics are connected mostly by means of a hollow waveguide with capacitive Coupling of the radiator sum signal.
  • planar antenna with downstream Electronics are the required dimensions of the individual assemblies disproportionately large by one sufficiently large reception or transmission power achieve so that the antenna is unnecessarily heavy in weight and becomes unwieldy, making use of such Spotlight systems for the handheld area is unsuitable.
  • manufacturing requirements are related on dimensions of the individual parts for the used Hollow waveguide very large, and the coupling of the Signals between planar antenna, waveguide and Electronics problematic, so that even at low Manufacturing deviations the signals from a component insufficiently coupled to the next. Also is a noise adaptation by means of such Hollow waveguide not possible.
  • JP-A-62-048103 a fastening part for a microstrip line antenna is known, by means of which the antenna can be connected to a coaxial conductor. It is based on a microstrip line antenna, which consists of a dielectric material, on one surface of which the microstrip line is attached and on the other surface of which the grounding conductor is attached. The grounding conductor has a much greater thickness than the dielectric material.
  • the generic microstrip line antenna of JP-A-62-048103 also has a fastening part which is fastened to the grounding conductor by means of screws. A central pin lies in the fastening part and is held in position by means of a cylindrical dielectric body.
  • the central pin has an area with a smaller diameter and an area with a larger diameter, the area with the smaller diameter penetrating the dielectric material and the microstrip line and being connected to the latter by means of solder.
  • Such a design of the center pin has advantages and disadvantages.
  • the advantage is that, on the one hand, the soldering of the free end of the part to the microstrip line and, on the other hand, the connection to the external circuits, not shown, is facilitated by the thicker area of the central pin.
  • JP-A-62-048103 now has the task of preventing these reflection and radiation losses.
  • JP-A-62-048103 proposes to extend the area of the center pin with a smaller outside diameter in the direction of the grounding conductor and to encase it in the area of the grounding conductor with a bushing made of a dielectric material, which creates an additional characteristic impedance arises and by means of which an impedance matching between the areas of different diameters of the central pin can be carried out.
  • JP-A-62-048103 proposes suitable diameters D 1 and D 2 .
  • a coaxial socket not disclosed by JP-A-62-048103 must be inserted into the fastening part. From JP-A-62-048103 an impedance matching in the fastening part is known.
  • the fastening part of JP-A-62-048103 is large in size relative to the dimensions of the planar antenna, as a result of which the connection of the planar antenna and the downstream electronics takes up a disproportionate amount of space.
  • the transmission losses of the fastening part are also large, as a result of which the efficiency of the antenna is adversely affected, since impedance-based adaptation of the planar antenna and the downstream electronics is not possible.
  • the object of the invention is therefore a radiator system with planar antenna, coupling element and downstream To miniaturize electronics that out parts are easy and inexpensive to manufacture and by means of an impedance matching between the planar antenna and the downstream electronics is possible.
  • the coupling element is advantageously only from a few parts that are easy to manufacture.

  • the Surface resonators are either square or rectangular.
  • the impedance matching of the components by means of the coupling element advantageously relatively easy due to the length and / or changes in diameter of sections A1, A2 and A3 from inner and outer conductors.
  • Advantageous dimensions can be determined with the help of suitable ones numerical approximation methods are determined, whereby the dimensional changes as well as material changes of a part to the dimensions to be selected or Material constants of the other parts.
  • a good impedance and noise matching is obtained with the values for the Coupling part. With the values described it is Radiator system for a frequency range of 11.70 - 12.50 GHz optimized.
  • An impedance matching can also be achieved in this way by the inner diameter of the outer conductor and the outer diameter of the inner conductor is chosen to be constant being, at the same time adjoining dielectric washers with different Dielectric constant between the base plates of Planar antenna and downstream electronics are arranged. The thickness of the respective washer and their material determines the wave resistance of the Section. Using a suitable numerical The optimal values can be calculated using the process.
  • the Planar antenna, as well as the downstream electronics are relatively inexpensive and easy to produce, which makes a big one, especially with large quantities Cost advantage results.
