  • the present invention relates to an antenna, in particular a helical antenna, use of such an antenna and a method of manufacturing such an antenna according to the preamble of claims 1, 15 and 16.
  • the design plays, i.e. the outer Appearance, when designing antennas a big one Role.
  • modern mobile devices increasingly not only in a cellular network, i.e. in one Frequency range, but in several frequency ranges be usable.
  • Multiband antenna systems are currently used, which consist of several individual antennas, for example of cylindrical symmetrical helical wire structures or planar antennas (eg so-called PCB boards).
  • a dual-band antenna which consists of a helix antenna and a parasitic element which is arranged next to the helix antenna but is not connected to it.
  • EP 0 893 841 A1 furthermore discloses an inexpensive manufacture of a helix antenna by punching out a thin sheet.
  • this helix antenna which can be operated in only one frequency band, is not mechanically sufficiently stable, so that in a further working step it is reinforced with non-conductive materials which have been applied using injection molding technology.
  • the present invention is therefore based on the object propose an antenna, which on the one hand is as possible easy and inexpensive to manufacture and on the other hand much leeway in the design of the exterior design Antenna enables.
  • the antenna should enable easy expansion to a multiband antenna.

  • the helical basic series connection of the convex curved antenna elements only by another parasitic antenna element in the form of an elongated web which runs parallel to the helix and is also arranged in such a way that the individual elements of the antenna, viewed in the longitudinal plane of the antenna do not overlap, so that this is also parasitic Antenna element together with the helical basic structure can be made from the same stamped and bent part.
  • the Parasitic and web-like antenna element is not just too connected in parallel to the helical base structure, i.e. at the lower antenna end connected to this, but especially so close to this helical Basic structure arranged that a clear electromagnetic coupling between the individual Antenna elements is given and on the other hand the construction volume the antenna becomes minimal.
  • the distributed Partial inductances and capacities of the individual Antenna elements are used in such a way that the thus a parallel connection and a series connection of preferably elliptically curved half rings and straight Are existing antennas in several frequency bands can be operated.
  • Antenna contact spring which is the electrical contact between the antenna and the electronics of it too produces operating device, in one piece from a single Stamped and bent part are manufactured, which is special is inexpensive because the antenna contact spring with the Basic antenna structure during the same production step can be manufactured.

However, the antenna elements 2, 3 can also run at an angle to each other. From Fig. 1 it can be seen that the individual elements of this helical antenna are arranged in this way are that they - viewed in the longitudinal direction of the antenna - Do not overlap at any point, which otherwise the punching process would hinder or even make impossible.
