Abstract
An antenna transponder configuration, in particular for power transmission and angle measurement is described. The antenna transponder configuration contains a stationary antenna device having at least two concentric coils with different mean radii, the mean magnetic flux in the interior of the coils approximately canceling itself out. At least one of the coils is in this case in the form of a meandering coil. A transponder, which is disposed such that it can rotate, has a configuration of coils that are inductively coupled to the magnetic field of the meandering coil. The transponder and the antenna device are separated from one another by an air gap.
