The invention relates to a multilayer film element (1) and to a method for producing the same. The multilayer film element (1) comprises a flexible dielectric carrier layer having a layer thickness of less than 800 μm. Furthermore, it comprises a first electrically conductive layer, in which a first coil-shaped conductor track (27) is shaped in a first region (71) of the film element, and a second electrically conductive layer, in which a second coil-shaped conductor track (37) is shaped in the first region (71). The dielectric carrier layer is arranged between the first and second electrically conductive layers, and the first and second conductor tracks (27, 37) overlap at least in regions and are coupled to one another to form an antenna structure. A first conductor track section (28″) comprising at least a three-quarter turn of the first coil-shaped conductor track (27) overlaps at least in regions a second conductor track section (38″) comprising at least a three-quarter turn of the second coil-shaped conductor track (37) with respect to a direction (63) perpendicular to the plane spanned by the carrier layer. |
