Summary:Global UHF-RFID metal tags are highly desired in the automotive, aircraft and energy sectors. The traditional solution to implement global tags is utilizing broadband tag antennas. However, most existing broadband metal tags cannot cover the ETSI and FCC bands simultaneously. This paper proposed a dual band metal tag to solve the problem. The overall dimension of the tag is only 26.5 mm × 26.5 mm × 3 mm. Moreover, the proposed tag delivers a unique orthogonal-polarization feature. The linear-polarization achieved at the ETSI band is orthogonal to that presented at the FCC band. Measurement results demonstrate that the proposed metal tag provides read ranges up to 10 and 12 meters at the ETSI and FCC bands respectively.
