  • the front end disclosed in WO 96/19737 has a shielded one, as stated at the beginning Space for electrical circuits and two adjoining this space, which are designed as a transmitting antenna and receiving antenna.
  • the cavities for the transmitting and receiving antennas have the shape of horns in which Radiator elements (e.g. in the form of wires) are installed.
  • the shielding of the space accommodating the circuits is done on the one hand by a housing placed on the circuit board for the circuits and on the other hand by the walls of the antenna horns which are fixed on the side of the circuit board opposite the circuits.
  • the design of the front end of a radar device which can be found in the publication WO 96/19737, is relatively complex in terms of production technology because it consists of a large number of individual parts.

  • the ' features according to the invention not only lead to a simplification in terms of production, but also to a material saving, because the electrical circuits and the antenna arrangement are incorporated in a common housing and separate housing arrangements for the electrical circuits and for the antenna arrangement are therefore superfluous.

In addition, the pins can be easily soldered into the openings in terms of process technology, so that a permanent, less fault-prone contact between the transition line and a planar line can be produced on the printed circuit board.
  • An improvement in the electrical contact between the transition line and the planar line and also the mechanical stability of the transition line can be achieved in that there is at least one further pin extending from the line arm, which is angled perpendicularly with respect to the other pin (s), so that when the line arm is inserted into the circuit board, it lies on a conductor track of the planar line and can thus be contacted.
