Claim 0:
1. Antenna arrangement, comprising:
a magnetic antenna comprising a loop interrupted one or several times and at least one tuning element for tuning the magnetic antenna, and
a tuner connected to the tuning element,
wherein the tuner is configured to provide a control signal for tuning the magnetic antenna in dependence on a phase position of a signal advancing into the magnetic antenna, and to control the tuning element with the control signal to tune the magnetic antenna,
wherein the tuner is configured to provide the control signal for tuning the magnetic antenna in dependence on a phase relationship between the signal advancing into the magnetic antenna and a phase signal,
wherein the tuner is configured to derive a signal from the signal advancing into the magnetic antenna to obtain a derived signal,
wherein the tuner is configured to provide the control signal for tuning the magnetic antenna in dependence on a phase relationship between the derived signal and the phase signal,
wherein the tuner comprises a signal combiner configured to combine
the phase signal or a phase-shifted version of the phase signal, and
the derived signal or a phase-shifted version of the derived signal, to obtain a combined signal,

wherein the tuner is configured to control the tuning element with the control signal to regulate a DC component of the combined signal or a low-pass filtered version of the combined signal to a predetermined set value.
