Hybrid frequency contactless transponder unit, module for and method of manufacturing

摘要

The contactless transponder unit (6) comprises a chip module (1), a first antenna (7) connected to said two upper conductive contact zones (4) of the chip module (1) and a second antenna (8) connected to said two lower conductive contact zones (5) of the chip module (1). The chip of the module is configured in such a way as to operate the first antenna (7) at a first frequency range and the second antenna (8) at a second frequency range, the first frequency range being different than the second frequency range.
