Abstract
A data carrier configuration includes a semiconductor chip. A first conductor loop is connected to the semiconductor chip and has at least one winding and a cross-sectional area with approximately the dimensions of the semiconductor chip. At least one second conductor loop has at least one winding, a cross-sectional area with approximately the dimensions of the data carrier configuration and a region forming a third loop with approximately the dimensions of the first conductor loop. The third loop inductively couples the first conductor loop and the at least one second conductor loop to one another. The first and third conductor loops are disposed substantially concentrically.
