Abstract
An RF air coil transponder includes a rotatable carrier, such as a rigid reel. A coil is wound about the reel and at least one field influencing body for influencing the electric and/or the magnetic field within the coil is supported by the reel. The rigidity of the reel enables the coil to keep its form and guarantees precise distances between windings, especially when a winding machine forms the coil. Adjusting the angular position, shape, composition, size, and/or surface are of the body effects adjustment of the resonant frequency.
