Abstract
The present embodiments include a magnetic resonance antenna having parallel-running longitudinal antenna rods arranged in a birdcage structure and antenna ferrules connecting the parallel-running longitudinal antenna rods at ends of the parallel-running longitudinal antenna rods in radio frequency terms. The magnetic resonance antenna includes a plurality of radio-frequency switching elements configured to interrupt at least a part of the parallel-running longitudinal antenna rods to detune a natural resonance frequency with respect to an operating magnetic resonance frequency in radio frequency terms. At least some radio-frequency switching elements of the plurality of radio-frequency switching elements are arranged at end sections of the parallel-running longitudinal antenna rods.
