Antenna transponder arrangement for power transmission and angle measurement

摘要

The arrangement includes a stationary antenna (2) with a meander antenna line (6) for generating a spatially changeable meander magnetic field. A rotatable transponder (3) acts together with the antenna. The transponder includes coils (10) which are inductively coupled to the meander magnetic field. The coils are arranged in such way that the single induced voltages are added. The transponder and the antenna are divided by an air gap (13). The antenna includes at least one antenna loop line (8) which is evenly formed and which is surrounded by the inner and outer meander antenna line.
