Antenna for the reception of circularly polarized satellite radio signals for satellite navigation on a vehicle

摘要

An antenna for the reception of circularly polarized satellite radio signals comprises a conductor loop that is arranged above a conductive base surface and that is configured as a ring line radiator that forms a resonant structure. Vertical radiators extending toward the conductive base surface are present at the periphery of the ring line radiator, with the excitation of the conductor loop taking place via one of the radiators as an active radiator. A specific number of passive vertical radiators galvanically coupled to the ring line radiator is furthermore provided.
