RFID devices using metamaterial antennas

A radio frequency identifier (RFID) tag can comprise an RFID chip, an antenna provided by a patch cell stack; and a feed line electrically coupling the RFID chip to the antenna. An equivalent circuit for the patch cell stack can comprise at least one inductance group comprising at least two series i...

Zusammenfassung:	A radio frequency identifier (RFID) tag can comprise an RFID chip, an antenna provided by a patch cell stack; and a feed line electrically coupling the RFID chip to the antenna. An equivalent circuit for the patch cell stack can comprise at least one inductance group comprising at least two series inductances, and at least one shunt capacitance. The antenna can have a composite right- and left-handed (CRLH) structure.
