Definitions

  • the conductive coating serves for reflection of heat rays and thus, for example, in motor vehicles or in buildings for improving the thermal comfort. In many cases, it is also used as a heating layer to heat a transparent pane over its entire surface electrically.
  • transparent coatings can also be used as surface antennas for receiving electromagnetic waves because of their electrical conductivity.
  • the conductive coating is galvanically or capacitively coupled to a coupling electrode and the antenna signal is provided in the edge region of the disk.
  • the antenna signal is supplied to an antenna amplifier, which is connected in particular to the electrically conductive body in motor vehicles, whereby a high frequency technically effective reference potential for the antenna signal is predetermined by this electrical connection.
  • the usable antenna voltage results from the difference between the reference potential and the potential of the antenna signal.
  • the antenna structure of the present invention comprises at least one electrically insulating, preferably transparent substrate, and at least one electrically conductive, preferably transparent coating which at least partially covers at least one surface of the substrate and at least partially serves as a planar antenna (surface antenna) for receiving electromagnetic waves.
  • the conductive coating is adapted for use as a planar antenna and For this purpose, it can cover the substrate over a large area. Due to the fact that it can also be used to transmit electromagnetic waves, the planar antenna is referred to here and below as a "surface radiator".
  • the antenna structure can be realized for example in the form of a single-pane glass. Alternatively, the antenna structure according to the invention can be realized, for example, in the form of a composite pane.
  • the antenna structure according to the invention furthermore comprises at least one first coupling electrode electrically coupled to the conductive coating for coupling useful signals out of the planar antenna.

  • the second coupling electrode is preferably above for a frequency range a cut-off frequency of 170 MHz selectively permeable.
  • the second coupling electrode is arranged near the first coupling electrode.
  • antenna signals at the various coupling electrodes are coupled depending on the potential difference and distance to a surface portion of the surface coating antenna conductive coating: the greater the potential difference between a surface portion of the conductive coating and the coupling electrode and the smaller the distance to this surface portion, the more signal is decouple the coupling electrode (and the less signal is then coupled out at another, "competing" coupling electrode).
  • the spatially close arrangement of the two coupling electrodes that occurring during signal reception potential differences are substantially equal for both coupling electrodes. Due to the frequency-selective transmission behavior of the second coupling electrode, it can furthermore be achieved that interference signals are coupled out via the second coupling electrode and useful signals via the first coupling electrode. Due to the spatially close arrangement of the two coupling electrodes can also be achieved that noise of all interfering with the surface antenna interference sources above the threshold or passage frequency of the second coupling electrode reliably and safely be coupled out of the surface antenna. The signal / noise ratio of the surface antenna can be significantly improved.

  • the close arrangement of the second coupling electrode at the Störttlen preparationzone causes upon receipt of the interference signals of the interference source potential differences between a Störttlen preparationzone containing surface portion of the surface antenna and the second coupling electrode, which are larger than potential differences between this surface portion and the first coupling electrode, so that the interference signals predominantly from the second coupling electrode are coupled out.

  • the second coupling electrode is capacitively coupled to a conductive structure acting as a ground.
  • a frequency-selective transmission behavior of the second coupling electrode is adjustable in a simple manner by the capacitive properties of the electrical coupling.
  • the second coupling electrode with the interposition of a frequency-selective component, such as a capacitor is galvanically coupled to the acting as a mass conductive structure.
