A radio-frequency antenna for acquisition of a magnetic resonance signal
has two electrodes that are connected with one another via a discrete
tuning device. The first radio-frequency antenna) is tuned to a resonance
frequency by the tuning device. The tuning device has a first tuning
element influencing the resonance frequency of the radio-frequency
antenna and a second tuning element influencing the resonance frequency
of the first radio-frequency antenna. The tuning elements are connected
in series and fashioned as inductors. The radio-frequency antenna also
has two tap points at which an acquisition signal representative of the
acquired magnetic resonance signal is tapped and conducted away via feed
lines. The tap points are respectively arranged between the electrodes
and the tuning element and one of said tap points is between the first
and second tuning elements.
