Abstract

A magnetic resonance device with a measurement chamber, an antenna arrangement that has a plurality of antenna elements arranged at least in certain areas around the measurement chamber, a gradient coil system arranged outside the antenna arrangement as seen from the measurement chamber, and a high-frequency shield system arranged between the antenna arrangement and the gradient coil system are provided. The high-frequency shield system has a reflector array with a plurality of passive reflector resonance circuits, each of which is configured such that resonance frequencies of the plurality of passive reflector resonance circuits lie below an operating magnetic resonance frequency of the magnetic resonance device and that the plurality of passive reflector resonance circuits has an inductive overall impedance.
