Abstract:
A method for producing a radio frequency identification transponder includes providing a conductive sheet covered by a mask layer, processing the mask layer by a laser beam so as to form an exposed portion of the conductive sheet, wherein the processing is carried out after a radio frequency identification chip has been attached to the conductive sheet, and etching the exposed portion so as to form a groove in the conductive sheet, wherein the groove defines an edge of an antenna element of the transponder.
