Definitions

  • the invention relates to a supply line for an antenna system of a vehicle, comprising at least one arranged between two connection points electrical conductor, and an antenna system with such a lead according to the features of the respective preambles of the independent claims.
  • Printed film antennas are currently being installed in different versions in vehicles. Many RF services can be covered with such foil antennas. Today, radio, TV, mobile communications and other communication antennas are realized with this technology.
  • antennas are not visible, i. integrated into spoilers, bumpers, fenders or other plastic parts of the vehicle.
  • An important installation space for antennas in the vehicle is the disc, especially the rear window, which normally contains whole antenna systems (for example FM, DAB, TV).
  • These (antenna) structures are applied with the aid of silver ceramic pastes.
  • the surface conductance of such antenna structures is not very good.
  • Another disadvantage is the minimum width of a trace of about 0.5 millimeters to 1 millimeter (mm).
  • Antenna systems for vehicles so-called pane antennas, have a carrier, for example a plastic film, with at least one antenna structure arranged thereon, which has a foot point, wherein at the base point a supply line is connected.
  • a carrier for example a plastic film
  • at least one antenna structure arranged thereon, which has a foot point, wherein at the base point a supply line is connected.
  • This carrier is usually arranged on or in a pane of a vehicle, preferably the rear window, for which it is necessary to provide the base of the antenna structure with a feed line, either to send high-frequency signals to the antenna structure via this feed line, so that they from there can be emitted, and / or to be able to pass on the high-frequency signals received with the antenna structure to a downstream electronic device.
  • this feed line is used as a cable with an inner conductor and an outer sheath, in particular a coaxial cable.
  • the invention is therefore based on the object to provide a supply line for an antenna system of a vehicle and also such an antenna system with which the above-described disadvantages are avoided.
  • a supply line for an antenna system in which the electrical conductor is formed by at least two conductor tracks arranged on a carrier.
  • the presence of at least two, preferably exactly three or even more than three strip conductors has the advantage that when one of the strip conductors is damaged, in particular severed, the further signal transmission is ensured.
  • the support can be laid without problems, especially if it consists of a flexible or thin rigid material.
  • such a supply line can then be used in the field of vision of a vehicle window of a vehicle when the carrier is transparent.
  • the presence of the lead in the field of view of the disc does not obstruct the viewer's perusal. This is especially true even if the tracks are very thin, preferably designed with a width of one micron to 100 microns.
  • the at least two conductor tracks run parallel to one another in the region between the two connection points.
  • These two interconnects are connected in quasi-parallel fashion between the connection points, so that when an electrical interruption of one interconnect takes place, the other interconnect still ensures the signal transmission.
  • the at least two conductor tracks intersect at least once in the region between the two connection points.
  • three strip conductors are arranged on the carrier repeatedly crossing between the two connection points. This makes it possible to ensure a particularly good signal transmission, in particular even in the event that once again a printed conductor or even two printed conductors have been interrupted.

This has not only advantage during the use of the supply line in the vehicle, but also in the storage and, above all, during installation, since any damage does not lead to a failure of the entire antenna system.
  • the individual strip conductors have a width of one micrometer to 100 micrometers, since they are not perceived by a viewer or only insignificantly due to this very thin width when the supply line is in the field of vision of a vehicle window.
  • the carrier is a transparent plastic film, whereby thin rigid transparent carrier can be considered.
  • transparent plastic films have the advantage that they can be laid, for example folded, kinked, bent, rolled or the like, depending on the installation space conditions.
  • a supply line in a region starting from the one connection point is designed to be planar, while in the further course it is angled or rolled to the other connection point, in order to thus realize an adaptation to the space requirements.

  • the antenna structure in the region in which the carrier of the antenna system merges into the carrier of the feed line also made continuous are and thus pass over.
  • the surface of the carrier for the antenna structure may be large in area to accommodate the respective antenna structures for the respective frequency range, whereas the carrier for the lead from the large area protrudes, for example, as a kind of narrow tab or "tail."
  • the length of this protruding part of the carrier for the lead in turn depends on the space requirements, especially after, where the lead must be performed to contact the connection point at the end with an electronic device (for example, an amplifier, a trap circuit, a display device or the like) to become.
