Abstract

The disclosure relates to a compensation capacitor for an antenna of a magnetic resonance scanner and a corresponding antenna with a compensation capacitor. The compensation capacitor has a first electrode and a second electrode arranged in parallel. An insulation material configured to resist high voltages and a dielectric with low dielectric losses are arranged between the first and the second electrode. The second electrode and/or the dielectric may be moved relative to the first electrode such that a surface area of a projection of the surface of the first electrode along the surface normal of the first electrode to the surface of the second electrode and/or the dielectric is variable.
