Definitions

  • the invention is based on a vehicle antenna according to the preamble of claim 1.
  • Such a vehicle antenna is already known (EP-A1-0 261 762), in which a slot antenna for AM and FM reception is built into the roof of a motor vehicle.
  • the known vehicle antenna has the disadvantage that its reception characteristic or transmission characteristic has a relatively strong directionality.
  • the invention has for its object to develop a vehicle antenna according to the preamble of claim 1 such that it has the most uniform all-round directional characteristic as a transmitting and receiving antenna.
  • a vehicle antenna according to the preamble of claim 1 by the features specified in the characterizing part of this claim.
  • the advantages that can be achieved with the invention consist in particular in the fact that the vehicle antenna, as the transmitting and / or receiving antenna, has an all-round directional characteristic that is as uniform as possible. Another advantage is that the antenna is not visible from the outside and is therefore theft-proof. The antenna is also washable.
  • a preferred field of application for the antenna is a motor vehicle transmission and reception antenna.
  • 10 denotes a motor vehicle, on or in whose metallic body 11 there are three slot antennas 12, 13 and 14 which are insulated from the body.
  • the slot antenna 12 has, for example, the shape shown in FIG. 2, that is, it consists of a flat, rectangular sheet metal part 15 with a longitudinally symmetrical slot 16. This slot antenna is mounted in or on a side door 17 of the motor vehicle 10.
  • the slot antennas 12 and 13 have, for example, the configuration shown in FIGS. 3 and 4, that is, they consist of a U-shaped sheet metal part 20, the base 21 of which contains a longitudinally symmetrical slot 22.
  • the slot antenna 13 or 14 is preferably attached behind a motor vehicle license plate 23; see. Fig. 4.
  • the three slot antennas 12, 13 and 14 each connect an antenna cable 25, 26 and 27, which is preferably a coaxial cable, with a central feed point 28, which with the output or the input of a radio transmitter and receiver 30 in Connection is established.
  • the cables 25, 26 and 27 are dimensioned so that they each n. ⁇ / 2 are long, where n is an integer and ⁇ is the mean operating wavelength.
  • the three slot antennas 12, 13, 14 can also be electrically connected in series.
  • at least one of the slot antennas can be designed as a vehicle window antenna known to the person skilled in the art, in which a conductive covering which contains a slot is fitted in or on the window.
  • the vehicle antennas are suitable, for example, for a frequency range of approximately 500 MHz if the length is approximately 550 mm, the slot length is approximately 350 mm and the slot width is approximately 7 mm.
