Definitions

  • the invention relates to an antenna arrangement, which has a carrier on which at least one antenna element is arranged, and a printed circuit board, connecting means being provided which electrically connect the at least one antenna element to a contact region of the printed circuit board, according to the features of the preamble of the patent claim 1.
  • an antenna arrangement in the form of a roof antenna arrangement, which has an antenna hood as a carrier, wherein a rod antenna is arranged on the antenna hood as an antenna element.
  • the foot of the rod antenna is screwed with a threaded piece in a corresponding mating thread in the antenna hood, wherein an electrical contacting of the rod antenna via electrical connection means with electronic elements takes place under the antenna cover.
  • the electrical connection via these connecting means is satisfactory, but the assembly is unsatisfactory, since it requires a lot of effort. So the threads must be provided so that the rod antenna can be screwed into the mating thread.
  • the mating thread in turn must be continued via connecting means and contacted at the corresponding point below the antenna hood.
  • the object of the invention is to improve an antenna arrangement, in particular a roof antenna arrangement, in comparison to the known state of the art, in particular with regard to its ease of assembly.
  • the connecting means are designed as an electrically conductive connecting foil having a contact surface, wherein the contact surface of the connecting foil rests against the contact region of the printed circuit board when the carrier is intended to be connected to the printed circuit board.
  • a connecting foil has the precedence that there are great freedoms with regard to the laying of the connecting foil; in particular, the connecting foil can be moved freely from its contact area to the antenna element or can adapt to the shaping of the carrier.
  • such a connecting foil may, for example, be clipped, latched, glued or the like to the carrier as it follows its contours.
  • a further significant advantage according to the invention can be seen in the fact that the connecting foil, which produces the electrical connection between the antenna element and its contact region, can be arranged on the carrier such that a contacting between the contact region of the connecting foil and a contact surface of the PCB occurs when the carrier is properly assembled with the circuit board and permanently connected. This means that contacting automatically takes place automatically when the carrier and circuit board are connected together. As a result, not only the assembly effort is significantly reduced, but also increases the reliability of contact because no parts can be forgotten if they have already been arranged preparatory to the circuit board and to the carrier.
  • the connecting foil is arranged with its contact surface on the carrier and the contact surface of the connecting foil is connected in electrical operative connection with the contact region of the circuit board, when the carrier is intended to be connected to the circuit board

While it is conceivable, on the one hand, that the rib (generally the anvil) exits directly from the surface of the carrier, in this variant with the at least one slot there is the advantage that the rib is somewhat yielding with respect to the carrier, if carrier and PCB are brought together as intended. By means of this at least one slot, therefore, it is possible to realize the prestressing when the contact region of the connecting foil comes into contact with the contact region of the printed circuit board by means of the rib and is pressed against it.
  • the connecting foil with its contact surface is arranged at least partially around at least a partial region of the counter-holder, in particular around the free end region of the rib.
  • the contact surface of the connecting foil for forming an electrical contact on the rib (generally on the anvil) is determined and at the same time a kind of pin-shaped or lance-shaped contact is formed, which forms a corresponding contact surface of the connecting foil to the contact region of the printed circuit board.
