Abstract: A foil element and a method for producing such a foil element. The foil element includes a dielectric carrier layer, which spans an xy plane of a Cartesian coordinate system having an x-axis, a y-axis and a z-axis, and at least one electrically conductive layer which is arranged on the carrier layer and in which a conductor track is shaped in a frame-shaped region of the foil element. The frame-shaped region is formed by the area of a larger, outer rectangle having sides each running parallel to the x-axis or y-axis, from which area the area of a smaller, inner rectangle with the same orientation as the outer rectangle is cut out. A mechanical property of the carrier layer is different along the x-axis and the y-axis. More than 50% of the length of at least one conductor track section runs obliquely with respect to the x-axis and the y-axis.

Abstract: The invention relates to a foil element (1) and to a method for producing such a foil element. The foil element (1) comprises a dielectric carrier layer (10), which spans an xy plane (E) of a Cartesian coordinate system having an x-axis (61), a y-axis (62) and a z-axis (63), and at least one electrically conductive layer which is arranged on the carrier layer (10) and in which a conductor track (27) is shaped in a frame-shaped region (5) of the foil element (1). The frame-shaped region (5) is formed by the area of a larger, outer rectangle (80) having sides (81, 82, 83, 84) each running parallel to the x-axis (61) or y-axis (62), from which area the area of a smaller, inner rectangle (90) with the same orientation as the outer rectangle (80) is cut out.
