Abstract:
1. An antenna for reception of circularly polarized satellite radio signals, comprising: at least one conductive base surface; at least one conductor loop oriented horizontally above said conductive base surface, wherein said conductor loop is configured as a ring line radiator having a structure, and formed by means of a polygonal or circular closed ring line, in an substantially horizontal plane, spaced apart from said conductive base surface by a height h; an antenna feeder comprising an arrangement for electromagnetic excitation of said at least one conductor loop; at least one antenna connector coupled to said arrangement for electromagnetic excitation; wherein said ring line radiator forms a resonance structure that is electrically excited by said arrangement for electromagnetic excitation, so that a current distribution of a running line wave in a single rotation direction occurs on said at least one conductor loop, a phase difference of which, over one revolution, amounts to substantially 2π; at least three vertical radiators which run toward said conductive base surface which are disposed on a circumference of said ring line radiator, said at least three vertical radiators being spaced apart at equally long extended length distances of the structure of the ring line radiator, wherein at least two of said vertical radiators are electromagnetically coupled both with said ring line radiator and with said electrically conductive base surface, and at least one vertical radiator is coupled to said excitation network, and thus to said antenna connector, to support a vertically oriented component of an electromagnetic field.
