Abstract
An inductive power transfer unit includes a winding unit for inductive power transfer during a power transfer operation, a flux guide, and an antenna. The antenna is arranged with the flux guide for generating or receiving an antenna signal during an auxiliary operation, wherein a compensation winding is arranged, such that the compensation winding compensates for an induced voltage and/or induced current in the antenna guide during the power transfer operation.
