摘要：The invention relates to a carrier assembly (99) for receiving an RFID

transponder chip (2), the carrier assembly (99) having an attachment side (S2) for beingattached to a consumer device. The carrier assembly (99) comprising: i) an antenna layer(50) comprising an antenna having contacts (T1, T2) for being coupled to the RFID

transponder chip (2); ii) a magnetic layer (70) covering at least part of an inner side of theantenna layer (50), wherein the inner side faces the attachment side (S2), and iii) anelectrically conductive shielding layer (90) covering at least part of the magnetic layer(70) at the attachment side (S2) of the carrier assembly (99). The invention also relates toan RFID transponder device comprising such carrier assembly, and to a consumer devicecomprising such RFID transponder device. The detuning effect due to the environment ismade less dependent of the environment, i.e. the detuning due to the electricallyconductive shielding layer (90) is dominant. The invention provides an RFID transponderdevice which may be applied to virtually any surface, even though it has been optimizedfor only one situation.
