RFID (radio frequency identification) tag, in particular for washable items

A RFID (Radio Frequency Identification) tag for washable items, the tag comprising:

• a module comprising:
• an ultra-high frequency (UHF) microchip connected to a near field UHF antenna arranged inside the module, the UHF microchip supporting radio communication at ultra-high frequency;
• and
• a high-frequency/near field communication (HF/NFC) microchip supporting radio communication at high frequency protocol;
• a UHF dipole antenna arranged on a textile or polymeric substrate to form at least one loop;
• and
• an air-coil high frequency HF metal antenna arranged outside the module,
• wherein said air-coil HF metal antenna and said module are arranged inside the at least one loop of the UHF dipole antenna,
• wherein the module includes a printed circuit board (PCB) substrate,
• wherein the UHF microchip, the HF/NFC microchip, and the near field UHF dipole antenna are arranged on a surface of the PCB substrate, and
• wherein the air-coil HF metal antenna is arranged around the PCB substrate.
