IC Tag Antenna Materials

A base material of copper or aluminum foil combined with an insulating film is etched to create the desired antenna circuit pattern. UACJ Foil supplies IC tags across a wide range of frequencies, from 13.56 MHz to 2.45 GHz. IC tags are projected to replace barcodes due to their capability for contact-free inventory management.

  • * Note: This product was jointly developed with a major RFID (radio frequency identification) manufacturer.

  • Product designs can employ aluminum or copper (rolled or electrolytic) foil.
  • Patterning methods can be tailored to reflect quantity and precision requirements.
  • Roll-to-roll production helps reduce costs.
