Abstract
Radio-frequency identification (RFID) tag antenna, tags and communications systems using the same are presented. The RFID tag antenna includes a patterned conductive loop having a plurality of longitudinal conductive sections and a pair of transverse conductive sections connecting to each end of the longitudinal conductive sections to serve as a matching network. A pair of extended conductive arms is electrically connected to the patterned conductive loop via two nodes. A bonding pad with an RFID chip disposed thereon is arranged at the central area of the pair of extended conductive arms.
