  • the antenna elements are designed as glued ladder bands or trim strips.
  • WO 02/23668 A1 also shows a bumper antenna arrangement with a conductive surface in the bumper. This surface forms with respect to the motor vehicle chassis (body panel) a slot that affects the Antennenstrahldia- program. Antenna connections at several points on the conductive surface can be used to gain signals for diversity operation.
  • WO01 / 59878 Al a arranged in the vehicle outside mirror antenna is known.

  • the actual attachment such as bumpers or mirrors must not be reconstructed consuming when it is to receive an antenna.
  • the fixture for the component is to be insulated from the chassis in order to be used as an antenna, e.g. B. holding device as a dipole or as a loop antenna or, if such isolation is not desirable, it is sufficient to take an insulated antenna conductor by the holding device or pass in tube-like design of the holding device.

  • an insulated antenna conductor can be easily passed through the tube.
  • the tube itself acts as a shielding for electromagnetic waves, but as in a conventional loop antenna at least the magnetic field component can be received with a pronounced directivity in the direction of the road, especially in truck mirror mounts, which is particularly advantageous for communication with lane-side signal systems or toll systems power.
  • these can advantageously be connected together to form an antenna system and enable a diversity operation by means of a switching device.
  • Metallic retainers may also preferably be split in the middle to receive insulation.
  • the individual parts can be set up as individual parts of a dipole or as individual receiving elements of a diversity receiving device.

  • Figure 1 shows a bow-like holding device 1 for a rearview mirror 2 of a truck 3. It usually consists of a bow-shaped metallic tube whose two ends are fixed to the metallic outer wall 4 of the truck cab and thus on the chassis. If the tube ends of the holding device 1 are electrically separated from the chassis via insulation 5, the holding device itself can be used as an antenna.

  • FIG. 2 shows the same arrangement as FIG. 1 with the difference that the holding device 1 has an insulating point 13 approximately in its center, in particular on the spine comb remote from the motor vehicle 3.

  • the antenna feed line 6 is not performed as in the figures 1 and 2 via a separate wall duct 62 in the vehicle interior, but continued as an insulated antenna conductor 63 through the inner tube 12 of the holding device 1 therethrough. If, as Figure 3 shows, the antenna conductor 63 is guided through the entire inner tube of the holding device 1 or 11 until the transition to the antenna feed line 6 at the re-exit at the other end of the tube, an antenna conductor loop forms, even in the absence of insulation of the holding device. 1 and 11, respectively, with respect to the chassis is adapted to receive the magnetic field component of a radio frequency signal.

  • the insulating point 13 on the spine of the holding device can also be extended so that the free ends of the antenna conductors 632 and 633 protrude into the insulation (FIG. 5) - this lengthens the antenna length for the electric field component with the possibility of targeted adjustment of the directivity.
  • the holding device 1, 11 caused by an extension of the isolation 13 by means of a suitable plastic less scratch marks especially when maneuvering the truck in the vicinity of buildings or other motor vehicles.

If this holding device 1 is electrically separated from the chassis of the motor vehicle 3 according to FIG. 6 by an insulation 16, the holding device 1 or a further metallic holding device 11 for the bumper can be used 15 are used as an antenna and connected to antenna feed line 6 and 61, respectively. Since the bumper 15 is usually made of plastic, the two holding devices are not electrically connected to each other. If the insulation 16 is missing and the metallic holding devices 1 to 11 consist of metallic pipe sections, an insulated antenna conductor 64 or 65 can be guided through the pipe sections of the holding devices 1 and 11, respectively, according to FIG.
