Abstract
A magnetic resonance coil arrangement for a magnetic resonance device includes at least two coil elements that may be read and/or controlled via an amplifier, and a matching circuit for power and/or noise matching between the at least two coil elements and the amplifier. Components of the matching circuit are dimensioned for wideband matching to a frequency band. The frequency band is limited by outermost relevant coupling modes that are displaced from the resonant frequency. The coupling modes occur due to the interaction of a coil element with at least one adjacent coil element.
