Abstract
In a method for producing an apparatus for wireless communication, particularly a contactless card, a E-passport, a Smart label or the like, or for producing a prelaminate for such an apparatus, an antenna is produced by applying an antenna structure to a substrate using an additive method, such as metal deposition. The substrate can be made of a PVC or polycarbonate material. A transponder is then produced by connecting a bare chip to the antenna using a direct assembly process, such as a flip-chip process. In a next step, the apparatus or the prelaminate for the apparatus is produced by connecting the transponder to further layers using a laminating method, wherein at least one of the further layers in directly adjoining relationship to the substrate is made of a same material as the substrate.
