Abstract
passive radio frequency identi¯cation (RFID) tag antenna with circular polar-
ization (CP) radiation is proposed to operate at 902{928MHz and mount on metallic surfaces.
A U-shaped terminal short-circuited feedline welded to a tag-chip is embedded in a rectangular
slot to achieve a coupled feeding and a good impedance matching. By employing two truncated
corners and two L-shaped slots with unequal length on the patch, a good left-hand circular
polarization (LHCP) and compact size are obtained. The measured impedance bandwidth of
the antenna is 85MHz (875{960 MHz), while the simulated 3-dB CP bandwidth is 6MHz (912{
918 MHz). The proposed tag antenna shows reasonable read ranges when mounted on the metal
plate in the following experiment.
