The RF in RFID: Passive UHF RFID in Practice. For those who want to know why things RFID are the way they are and what can be done about it, this book provides users of UHF RFID with an understanding of how identification information gets from a tag to a reader and in some cases back to the tag...

...tags block visibility of other tags in close proximity. are available in many different shapes, sizes and materials. Far-field UHF uses electromagnetic waves propagat-. Along with performance capabilities, it is crucial to con- ing between reader and tag antennas, delivering a wider. sider...

The need for harmonic mitigating devices is growing because of the rapid increase in variable speed drive (VSD) usage in industrial and commercial applications and the corresponding growth in harmonic-related problems. A new state-of-the-art passive universal harmonic filter (UHF) is designed...

...or production tracking can be a confusing task these days. With all the information fl oating. around about HF (High Frequency), UHF (Ultra High Frequency), microwave and GPS based systems, and. whether to use active or passive based tags, it may seem like these systems can be used almost anywhere...

This paper is an investigation of the feasibility of. applying a mechanically flexible magnetic composite material to. radio frequency identification (RFID) planar antennas operating. in the lower ultrahigh-frequency (UHF) spectrum (~300-. 500 MHz). A key challenge is that the magnetic loss...

...featured Write Once, Read Many (WORM) tags. Both of these companies and many others understand that the final EPC standard, being. referred to as Class 1, Generation 2 or UHF Gen2, require read write capabilities. Matrics, Alien, and other reader manufacturers have. introduced many new products...
