ABSTRACT:
A tunable radio-frequency unit for a magnetic resonance device has a radio-frequency antenna and a radio-frequency signal line connected to a signal terminal of the radio-frequency antenna. The length of the radio-frequency signal line corresponds to a whole-number multiple of a half-wavelength of a radio-frequency signal on the radio-frequency signal line, for a given operating frequency of the radio-frequency antenna. For switching a short circuit on and off, a switching arrangement is connected at an end of the signal line lying opposite the signal terminal.
