Abstract
A local coil system for detecting magnetic resonance (MR) signals in a magnetic resonance tomography (MRT) device includes an energy reception antenna for inductively receiving energy for the local coil system from a magnetic field changing over time with an energy transmission frequency. The energy reception antenna includes a conductor loop running in loop-like fashion from a first loop connection to a second loop connection. At least one path filter that blocks for harmonic frequencies of the energy transmission frequency is arranged over the course of the energy reception path, and/or at least one path filter that blocks for harmonic frequencies of the energy transmission frequency is arranged over the course of an energy reception path leading from the loop connections to a rectifier.
