Device and method for data transfer with high data rate between two parts moving relative to one another at a slight distance

A method for data transfer between two parts that are moving relative to one another while maintaining a slight distance between the two parts, said method comprising the steps of:

• transmitting signals by radiation via a non-galvanic transmission path using a transmission device mounted on a first of said parts moving relative to one another, said transmission device comprising at least one transmission antenna connected to a signal transmitter;
• receiving the transmitted signals using a reception device mounted on a second of said parts moving relative to one another, said reception device comprising at least one reception antenna connected with a signal receiver, at least one of said transmission antenna and said reception antenna being formed as a radio-frequency conductor;
• arranging said transmission antenna and said reception antenna respectively on said parts to cause signals fed into the transmission antenna from the signal transmitter to be received by the reception antenna via said non-galvanic transmission path during at least one segment of the relative movement between the first and second moving parts, by capacitive coupling or inductive coupling across said non-galvanic transmission path;
• and
• disposing at least one compensation device disposed between the signal transmitter and the signal receiver, and with said at least one compensation device, counteracting signal distortion that occurs on said radio-frequency conductor due to propagation of said signal in said radio-frequency conductor.
