Claim Text:
1. Multi-layer body comprising: a carrier having a surface on which a plurality of strip conductors and associated connections are arranged, in one layer, which have a width in the range of from 1 μm to 40 μm, wherein the strip conductors and their associated connections are arranged in patterns coupled to a plurality of touch pads on the surface such that the touchpads and certain of the connections are delimited by the patterns, of which touchpads of a first class serve as touchpads that couple out by emitting an electromagnetic field, and of which touchpads of a second class are electrically separated from the touchpads of the first class and serve to couple in by receiving an electromagnetic field, and wherein, for both classes of touchpads, a plurality of touchpads of the respective class are electrically coupled via a first portion of the connections; at least a second portion of the connections lead to at least one contact element outside of an area of surface having the touchpads at a first edge side, in that at least a first portion of the contact elements are coupled to in each case one contact element at a second edge side opposite the first edge side, via contact connection lines, which contact connection lines are provided by said strip conductors in a pattern, and in that at least some of the contact connection lines pass through the area of the surface having the touchpads, wherein a first distance (x′) between a contact connection line passing through a gap and a touchpad is smaller than a second distance (y) between touchpads of the first class and touchpads of the second class, wherein the first distance (x′) lies between 1 μm and 50 μm.
