Abstract
Abstract A circuit unit having an insulating substrate (1) on which a conductive, flat coil (3) is located. The coil (3) can consist of a plurality of coil layer sections (9, 17) separated by insulating layers (11). To interconnect the individual coil layer sections (9, 17) into a coil, at least one opening (13) is provided in each of the insulating layers (11). The connection between the first coil ends (15, 19) of the coil (3) and an integrated circuit (7) or a module (23) containing the integrated circuit (7) can be formed solely by the coil ends (15, 19) and the connection points (27) of the integrated circuit (7) or the contacts (25) of the module (23) touching. The individual turns of the coil (3) can be disposed and dimensioned so as to permit embossing of the circuit unit without restriction within an area (37, 38) conforming with the standard.
