Abstract EN
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 designed based on CPW open stub feed PIFA antenna.
By changing the length of the open stub, the impedance of the PIFA antenna could be tuned in a large scale for conjugate impedance matching.
The open stub makes it easy to tune the resonant frequency to alleviate the fabrication detuning or the environmental detuning, even after the manufacture.
Moreover, the CPW structure of the open stub feed can resist the effects of the metallic surface and increase the antenna gain for the compact PIFA antenna.
Modeling analysis and simulation are in good agreement with the measurement results.
It showed that the UHF RFID metal tag could be designed compact with good performance based on the CPW open stub feed PIFA antenna.
