In this paper a 3 bit chipless RFID tag able to be printed using mass production techniques is introduced. The structure proposed is based on dipole like structures and three of such dipoles conforms a tag. Several chipless RFID tag prototypes were fabricated on PET substrate and measured within the frequency band from 2 GHz to 5 GHz. In contrast to the already reported printed tags where inkjet printing is used, the proposed tag is fabricated using screen printing techniques which enable fast mass production of tags in a very short time with thick conductive tracks of ~10 μm. A good agreement between simulation and measurement was obtained and a reading distance up to 1 m is obtained with a transmission power of 3 dBm. The obtained results confirm the use of low cost printed tags for mass market applications.

“…Concerning chipless RFID tags, the interest in this work, transmission lines loaded with multiple resonant elements, each tuned to a different frequency, have been proposed as multi-resonant frequency domain based tags [31][32][33][34][35][36][37][38][39][40][41][42][43][44]. In such chipless-RFID systems, the interrogation signal is a multi-frequency sweeping signal covering the spectral bandwidth of the resonant elements, and the ID code is inferred from the dips present in the frequency response (retransmission based tags) [31][32][33][34][35][36][37] or in the radar cross section response (backscattered tags) [38][39][40][41][42][43][44], caused by the resonant elements. Therefore, the presence or absence of dips at predefined frequencies (each one corresponding to a different bit) is associated with the logic state '1' or '0'.…”

High data density and capacity in chipless radiofrequency identification (chipless-RFID) tags based on double-chains of S-shaped split ring resonators (S-SRRs)

Abstract. The data density per surface (DPS) is a figure of merit in chipless radiofrequency identification (chipless-RFID) tags. In this paper, it is demonstrated that chipless-RFID tags with high DPS can be implemented by using double-chains of S-shaped split ring resonators (S-SRRs). Tag reading is achieved by near-field coupling between the tag and the reader, a CPW transmission line fed by a harmonic signal tuned to the resonance frequency of the S-SRRs. By transversally displacing the tag over the CPW, the transmission coefficient of the line is modulated by tag motion. This effectively modulates the amplitude of the injected (carrier) signal at the output port of the line, and the identification (ID) code, determined by the presence or absence of S-SRRs at predefined and equidistant positions in the chains, is contained in the envelope function. The DPS is determined by S-SRR dimensions and by the distance between S-SRRs in the chains. However, by using two chains of S-SRRs, the number of bits per unit length that can be accommodated is very high. This chipless-RFID system is of special interest in applications where the reading distance can be sacrificed in favor of data capacity (e.g., security and authentication). Encoding of corporate documents, ballots, exams, etc., by directly printing the proposed tags on the item product to prevent counterfeiting is envisaged.

“…In recent years, rapid advancements in materials have led RFID tags to be printed on paper using conductive ink [6][7][8][9][10]. This type of fabrication has remarkably lowered the cost and size of RFID tags, but the low conductivity issue remains as a drawback.…”

This article proposes a design of chipless RFID tag with dipole array structure that is fully printable using conductive ink. The proposed tags encode data based on spectral signature modulations. The reading range is considerably increased (2 m) while maintaining low transmission power (1 mW). Several prototype chipless RFID tags were fabricated and measured in the SHF and UHF bands. The proposed dipole array structure enhances the antenna gain of the passive tags and contributes to overcoming the low conductivity of conductive ink. In order to verify the utility of our proposal, the tags are manufactured on paper, using conductive ink, for the purpose of economic mass production.
