  • Tunable Compact UHF RFID Metal Tag Based on CPW

    2012-3-20u2002·u2002For the ultrahigh frequency radio frequency identification (UHF RFID) metal tag, it always has the difficulties of compact designing, especially for the conjugate impedance matching, low antenna gain, and fabrication or environmental detuning. In this paper, a tunable compact UHF RFID metal tag is designed based on CPW open stub feed PIFA antenna.

    The antenna 44 geometry and properties depend on the desired operating frequency of the RFID tag 40. For example, 915 MHz or 2.45 GHz RFID tags 40 would typically include a dipole antenna, such as a linear dipole antenna or a folded dipole antenna. A 13.56 MHz (or similar) RFID tag 40 would use a spiral or coil antenna 44, as shown in FIGS. 5 ...
