Abstract
In a circularly polarizing local antenna for a nuclear magnetic resonance imaging apparatus, a first antenna system is fashioned as a frame coil. A second antenna system has two sub-coils arranged lying opposite one another, which are both penetrated by the frame coil. The combination of the first and second antenna systems exhibits a circularly polarizing characteristic in a volume that lies inside the frame coil and outside the subcoils.
