Inkjet-printable UHF RFID tag antenna on a flexible ceramic- polymer composite substrate

The utilization of inkjet-printing technique to develop a printable UHF RFID tag antenna on flexible ceramic-polymer composite material is demonstrated. The substrate material is fabricated using high permittivity Barium Titanate (BaTiO
3
) ceramic powder mixed with polydimethylsiloxane (PDMS) polymer. A UHF RFID tag antenna is inkjet-printed using silver nano-particle to exploit the potential advantages of high dielectric flexible composite material when used as a tag substrate. Our preliminary results yielded a small flexible UHF RFID tag antenna with read range comparable to commercially available tag antennas.
