Design and development of novel miniaturized UHF RFID tags on ultra-low-cost paper-based substrates

In this paper, an overview of design requirements and novel approaches for improved performance UHF radio frequency identification (RFID) tags is presented. Two matching techniques, inductively coupled structure and serial stub structure are discussed. Different antenna configurations are proposed, focusing on low-profile, low polarization mismatch and high directivity. Paper substrates, that could potentially utilize inkjet printing techniques, are also investigated for the realization of ultra-low-cost RFID tags.
