    Abstract: A system for electromagnetic excitation of an object under examination during magnetic resonance tomography includes a radio frequency (RF) device for generating a radio-frequency signal and a plurality of antennas for emitting the radio-frequency signal. A signal connection exists between the output of the RF device and the plurality of antennas. A source impedance of the signal connection to the output of the RF device at a connection point of the plurality of antennas is significantly higher than the impedance of the plurality of antennas at the connection points, so that the plurality of antennas are fed in a current source feed mode if a radio-frequency signal is present.

    Abstract: When a portion of a structure enclosing a local coil is inserted in a homogeneity region of a basic magnetic field of a magnetic resonance system, the local coil is operable to receive magnetic resonance signals originating from a specific detection zone for the local coil arrangement. At least one conductor is arranged in the structure. Field lines of a compensation magnetic field generated by current encircling the conductor form a compensation magnetic field angle with the basic magnetic field in an edge area of the detection zone. Return conductors complete an electric circuit containing the conductor and extend in the direction of the basic magnetic field and/or are arranged such that field lines of an interfering magnetic field counteracting the compensation magnetic field encircle the respective return conductor and form an interfering magnetic field angle with the basic magnetic field in the edge area.
