Abstract
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.
