A meandered line multi-resonator design is proposed for a chipless Radio Frequency Identification (RFID) tag. The tag is equipped with a set of identical resonant elements and two orthogonally polarized monopole ultrawide band (M-UWB) antennas. The proposed multi-resonator design is realized on an FR-4 substrate (ε r = 4.4; tan δ = 0.01) in a surface area of 13 × 17 mm 2 , occupying a coding density of 4.52 bits/cm 2 by encoding 10 bits of data. The bit is encoded using absence/presence coding and frequency shift coding technique. The data can be read and transmitted from the multi-resonator structure through the orthogonally polarized M-UWB antennas operating in the frequency range of 2 GHz to 4.5 GHz. The span of the meandered line multi-resonator design is 13 mm × 17 mm. The tag is designed using ADS software and tested using vector network analyzer (VNA).

Orientation Independent Chipless RFID Tag Using Novel Trefoil Resonators

In this paper, a compact and fully passive bit encoding circuit, capable of operating as a chipless radio frequency identification (RFID) tag is presented. The structure consists of novel concentric trefoil-shaped slot resonators realized using Rogers RT/duroid R 5880 laminate, occupying a physical footprint of 13.55 × 13.55 mm 2. Each resonating element is associated with a particular data bit, having a 1:1 resonator-to-bit correspondence. Bit sequences are configured through introducing modifications in the geometric structure either by addition or exclusion of each nested slot resonator. Such changes manifest directly in the electromagnetic signature of the tag as presence or absence of corresponding resonant peaks. The proposed 10-bit tag offers minimized inter-resonator mutual coupling and insensitivity to changes in polarization and incident angles thereby demonstrating orientation independent functionality. Moreover, error-free encoding is achieved through stabilizing the shift in resonant frequencies for a variety of different geometric configurations and orientation of the structure. The tag operates within the license-free ultrawideband ranging from 5.4 to 10.4 GHz, providing spectral bit capacity and bit density of 2 bits/GHz and 5.44 bits/cm 2 respectively. INDEX TERMS Chipless tag, on-off keying (OOK), radar cross-section (RCS), radio frequency identification (RFID).
