Abstract :
In contrast to the inductively coupled structure published earlier, a capacitively coupled structure in designing broadband radio frequency identification (RFID) tag antennas for the UHF band is investigated. The proposed structure not only successfully widens the tag operating bandwidth but also enjoys better radiation efficiency than its inductive counterpart
