Definitions

  • the invention relates to a multi-antenna arrangement for an antenna diversity system in a motor vehicle window pane with a heating field arranged therein, according to the preamble of claim 1.
  • Such multi-antenna arrangements are used for the reception of frequency-modulated signals, such as FM radio.
  • Such an antenna is known from EP-A-0 065 263.
  • This known multi-antenna arrangement for an antenna diversity system consists of two antennas on the rear window of a motor vehicle, one of which, referred to as the auxiliary antenna, through the heating field, the other, as the main antenna designated, is realized by an antenna conductor arranged in the free space above the heating field of the rear window.
  • the Terminal pair of the heating field antenna has a connection point on the lowermost heating conductor and a second ground connection point on the adjacent section of the window frame.
  • the invention is therefore based on the object, a multi-antenna arrangement for an antenna diversity system in a motor vehicle window pane according to the preamble of claim 1, preferably for reception in the range of the meter waves (VHF) with more than two antennas, so that the middle Reception quality with each individual antenna is as good as possible and the number of interferences that occur simultaneously in the signals of the different antennas is as low as possible.
  • VHF meter wave
  • RF decoupling within the meaning of claim 1 exists when the received signals of the antennas, in particular with regard to reception interference, such as e.g. Dips in the RF level are different.
  • FIG. 1 shows a window pane surrounded by a metallic frame, which is referred to below as the mass.
  • the heating surface is used for the formation of at least two FM antennas.
  • suitable pairs of terminals which are each formed from the conductor part connection point (5a, b) and an adjacent earth point on the frame, can be Manufacture FM antennas whose signals are largely independent of each other.
  • additional VHF antennas can be attached in the partial areas of the window which are not covered with conductors, the reception signals of which also differ from the other VHF antennas, in particular with regard to the interference to be avoided.
  • FIG. 1 shows a window pane surrounded by a metallic frame, which is referred to below as the mass.
  • the heating surface is used for the formation of at least two FM antennas.
  • the left half of the window above the heating surfaces is covered with a VHF monopoly (5c), which is designed as a parallel conductor that is combined at the connection point.
  • the dimensions of this monopoly are selected using the available space in such a way that the average reception power assumes the best possible value. With the usual vehicle dimensions, the width of which in the FM range is approximately half a wavelength, monopoles with a favorable length of a quarter wavelength can thus be realized.
  • the distances from the frame and from the heating fields are set favorably according to known aspects. In the example in FIG. 1, the space above the heating field in the right part of the window is used for the design of an LMK antenna according to known aspects.
  • the heating field generally represents a mass for the LMK frequency range, just like the window frame, in terms of radio frequency.
  • the dimensions according to the dimensioning of the LMK antenna are as set out in DOS-P 34 10 415.1 Viewpoints set.
