    摘要: Method and device for measuring two orthogonal electromagnetic field components using a cross coil and for evaluating the components in the distance measurement in electronically course-steered vehicles (13). For rapid and ensured detection of malfunctions of the distance measuring system, use is made of an antenna effecting concurrent positionally and timewise measurements, and with the coils each consisting of bifilar or trifilar coil wires representing a redundant measuring system. A monitoring unit is used to continuously compare the signals generated by the various wires of the antenna when scanning the magnetic field. When a malfunction occurs in one of the channels, vehicle steering control is continued by the respective other channel and the defect is indicated via the monitoring unit. As monitoring signals, use can also be made of direct currents superimposed in the coils.

    摘要: The present invention relates to a planar antenna (1) for excitation of the TE01-mode of an electromagnetic wave and adapted to be arranged in a waveguide tube (2). The planar antenna comprises a substrate (6) of dielectric material having a first surface (7) intended to face towards a filling good surface and a second surface (8) facing in an opposite direction. A first group (9) of a plurality of dipole arms (10) is arranged on the first surface (7) or the second surface (8) on a perimeter of a circle with a predetermined radius. A second group (11) of a plurality of dipole arms (12) is arranged on the first surface (7) or the second surface (8) on the perimeter of the circle with the predetermined radius. The dipole arms (10) of the first group (9) extend in a first direction and the dipole arms (12) of the second group (11) extend in a direction opposite the first direction. Furthermore, the present invention relates to an antenna system comprising a cylindrical waveguide tube (2) having a bottom plate (3) and a tube portion (4) and a planar antenna (1) as mentioned above.

    摘要: A vehicle window heater includes an arrangement of heating conductors provided on the window. A radio receiving antenna is located in the vicinity of the heating conductors. An interference-suppressing arrangement decreases the effect upon the antenna of interference fields emanating from the heating conductors and includes an arrangement of auxiliary conductors located in the vicinity of the heating conductors. The auxiliary conductors along their lengths are insulated from the heating conductors. Each auxiliary conductor at at least one of its ends is conductively connected to the vehicle body for high-frequency condition.
