An RFID tag to be used, for example, for tagging livestock. The RFID tag has a high resistance to mechanical and thermal stress due to a physical separation of a main antenna and an integrated circuit forming an RFID circuit. The RFID tag may comprise an inlay with the main antenna and a chip module with the integrated circuit and a loop antenna inductively coupled to the main antenna. The inlay and the chip module are safely embedded in a tag housing. The compact chip module with electrical connections between the loop antenna and the integrated circuit can be reliably protected.
