Abstract:
1. An antenna for reception of satellite radio signals emitted circularly in the direction of rotation of polarization comprising: a) a conductive base surface; b) an antenna connection point; c) an additional element connection point; d) at least one antenna output connector; e) at least two antenna elements comprising: f) a plurality of networks comprising a matching network and a phase shifter network configured to connect said at least two antenna elements to said at least one antenna output connector wherein said additional element connection point and said at least one loop antenna are coupled to each other by said plurality of networks, wherein in reciprocal operation of the antenna, the radiation fields of said loop antenna and of said at least one additional antenna element are superimposed with different phases in a far field of the antenna; wherein said at least one additional antenna element has a polarization orientated substantially perpendicular to the polarization of said loop antenna and an essentially orthogonal phase in the far field.
