DUAL-LOOP INDUCTIVELY-COUPLED RFID TAG FOR AGGRESSIVE ENVIRONMENTS

摘要

The invention relates to an RFID tag for the UHF-SHF range, meant to operate in agressive industrial media. According to the invention, the RFID tag comprises a UHF-SHF antenna (2), made of an electroconductive textile thread, electrically insulated, embroidered on a textile carrier, an encapsulated RFID transponder (3), inductively-coupled with the antenna (2), and a sub-layer of textile material (4) on which the RFID transponder (3) and the UHF-SHF antenna (2) are placed, where the UHF-SHF antenna (2) has a central area consisting of a dual loop (5) though which it is inductively-coupled with the encapsulated RFID transponder (3).
