Performance of inkjet-printed narrow-line passive UHF RFID tags on different objects

Inkjet-printing offers a potential alternative to conventional tags manufactured by etching. The inkjet-printed narrow-line tags discussed in this paper are fabricated using less conductive materials than conventional tags. This paper presents the performance of the narrow-line tags when used on different materials. We present read range comparison of passive ultra high frequency (UHF) inkjet-printed narrow-line radio frequency identification (RFID) tags in air and attached to diverse objects. We have also compared the results to a dipole-type commercial copper fabricated tag. Measurement results show that materials under identification affect narrow-line tag performance such as read range and operational frequency and bandwidth.
