ABSTRACT:
An antenna arrangement for a magnetic resonance imaging apparatus is composed of an array having at least three linearly polarized local coils which mutually overlap to such an extent that they are geometrically decoupled. Each local coil is separately connected to a combination network wherein a complex operation between the output signals of the respective local coils is produced such that a radio-frequency signal corresponding to a circular polarization is obtained.
