An RFID tag (10) to be used, for example, for tagging livestock is disclosed. The RFID tag (10) has a high resistance to mechanical and thermal stress due to a physical separation of a main antenna (18) and an integrated circuit (22) forming an RFID circuit (26). Namely, the RFID tag (10) comprises an inlay (14) with the main antenna (18), and a chip module (20) with the integrated circuit (22) and a loop antenna (24) inductively coupled to the main antenna (18). The inlay (14) and the chip module (20) are safely embedded in a tag housing (12). In particular, the compact chip module (20) with the electrical connections between the loop antenna (24) and the integrated circuit (22) can be reliably protected.
