N2 - This paper presents a polarization-independent 11-bit chipless RFID tag
based on frequency-selective surface which has been designed for
encoding and relative humidity (RH) sensing applications. The 10
exterior U-shaped resonators are used for item encoding whereas Kapton
has been incorporated with the interior resonator for RH sensing. This
radio-frequency identification (RFID) tag operates in S- and C-frequency
bands. The proposed design offers enhanced fractional bandwidth up to
88% with the density of 4.46 bits/cm2. Both
single- and dual-layer tags have been investigated. The simulated
results are in good agreement with measured results and a comparison
with existing literature is presented to show the performance. Simple
geometry, high code density, large frequency signature bandwidth, high
magnitude bit, high radar cross-section, and angular stability for more
than 75° are the unique outcomes of the proposed design. In addition, RH
sensing has been achieved by integrating the Kapton on the same RFID
tag.
