Abstract
A method for manufacturing a tag encompassing an antenna or coil that is capable of at least one of wirelessly transmitting information to remote receivers and receiving information from remote transmitters. The method includes die-cutting a coil or antenna shape from an electrically conductive flat double foil having an upper electrically conductive flat foil layer of a soft, inelastic metal and a lower synthetic film substrate layer, the die-cutting including cutting with a die-cutting tool having a single die-cutting blade which matches the desired antenna or coil shape, the blade completely perforating the upper electrically conductive flat foil and at least partially separating the lower synthetic film substrate so that a gap the distance created in the flat foil by die-cutting remains after the die-cutting tool is removed. Subsequently the cut shape is bonded with additional layers including an electronic chip module.
