Abstract
An antenna for reception of satellite radio signals emitted circularly in the direction of rotation of polarization has a conductive base surface, an antenna connection point, an antenna element connection point and at least two antenna elements. The first antenna is a conductor loop disposed parallel to the base surface. The loop antenna has capacitors disposed along the conductor loop. The antenna connection point is coupled to an interruption of the loop antenna. This connection point feeds a ring current into the loop antenna. At least one additional antenna element extends between the antenna element connection point and the loop antenna. The additional antenna element has a polarization orientated perpendicular to the polarization of the loop antenna and an orthogonal phase in the far field.
