A Multitude of RFID Tags: A Broadband Design for Stackable Applications

RFID technology has been a part of our lives for a number years. However, research and development are ongoing to produce novel, improved tags for higher ranges working at lower power as well as to differentiate between tags in logistic applications for conventional chip-based RFIDs. Because of such improvements in already existing infrastructures and close-proximity scenarios, the second ultrahigh-frequency (UHF) RFID student design competition was held in May in San Francisco during the 2016 IEEE Microwave Theory and Techniques Society (MTT-S) International Microwave Symposium (IMS2016).
