Tunable Compact UHF RFID Metal Tag Based on CPW Open Stub Feed PIFA Antenna
For 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 d...
