In a device and a method for data transfer between two parts moving relative to one another while maintaining a slight distance between the parts, a transmission device with at least one transmission antenna (connected with a transmitter) and a reception device with a reception antenna (connected with a receiver are used). The transmission antenna and/or the reception antenna is/are fashioned as radio-frequency conductors and are arranged such that signals fed into the transmission antenna during at least one segment of the relative movement are received by the reception antenna by capacitive or inductive coupling. One or more compensation devices is/are arranged between the transmitter and the receiver. The compensation devices counteract signal distortion caused on the radio-frequency conductor by propagation of the signals. Higher data transfer rates can be realized in a cost-effective manner given the use of radio-frequency strip conductors as transmission and/or reception antennas.
