摘要： A contactless device includes a miniaturized antenna. The antenna includes an inductive coupling element that presents a field coupling surface area to couple to a magnetic field. The inductive element may be made of layers where conductive loops are formed parallel to the layers or perpendicular to the layers. When conductive loops are formed perpendicular to the layers, the effective field coupling surface area is increased. The inductive element is positioned on an outside edge of a memory card compatible device with the field coupling surface area perpendicular to the card.

摘要： The invention relates to a multilayer film element (1) and a method for the production thereof. The multilayer film element (1) comprises a flexible dielectric substrate layer having a layer thickness of less than 800 μm. The multilayer film element further comprises a first electrically conductive layer, in which a first coil-shaped conductor (27) is formed in a first area (71) of the film element, and a second electrically conductive layer, in which a second coil-shaped conductor (37) is formed in the first area (71). The dielectric substrate layer is arranged between the first and second electrically conductive layers, and the first and second conductors (27, 37) overlap at least in some sections and are coupled with each other to form an antenna structure. A first conductor section (28") comprising at least a three-quarter turn of the first coil-shaped conductor (27) overlaps, at least in some sections, a second conductor section (38") comprising at least a three-quarter turn of the second coil-shaped conductor (37) with regard to a direction (63) standing vertically on the plane spanned by the substrate layer.
