Study of an ENG-Inspired Two-Sided UHF RFID Tag Antenna

Abstract:

In this paper, a two-sided tag antenna’s equivalent circuit model and related formulas based on the complex impedance are derived to guide the design and adjustment of a tag antenna’s structure. An ENG-inspired NFRP element is introduced in the design of the tag antenna. A two-sided UHF RFID tag antenna, only 19.2×32×0.7mm³(0.059×0.098×0.002 λ_0³) in size, is proposed. Its central frequency is 915MHz which can be easily adjusted according to different requirements. The bandwidth of in S₁₁ in -3dB is 10MHz.
