We characterize a passive UHF RFID tag based on a stretchable dipole antenna which is screen printed on ultra-thin polyurethane substrate with silver ink. Our results show that the change in the conductor properties due to strain is large enough to modify the electromagnetic properties of the antenna notably, yet small enough so that the tag retains high performance even under 20-% strain. By comparing...
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...
This paper investigates the effects of conductor thickness on the performance of passive RFID tags fabricated using inkjet technology. Judging from the obtained results the performance of printed tags continues to increase as more conductive layers are added. However, the results show that the amount of performance improvement reduces with increase of the number of layers.
