Abstract
A laminate is formed from a carrier layer and an electrically conductive layer. In one section, the conductive layer is formed into an antenna structure. The laminate is formed by placing a mask onto a packaging film and vapor-depositing aluminum onto the packaging film and the mask. After removal of the mask, only a desired antenna structure remains on a section of the packaging film. Then a microchip, is adhesively bonded to the packaging film and conductively connected to an end of the antenna structure, so that data can be written in or read out without contact in a wireless transponder system.
