“…A Ultra-Wideband (UWB) impulse radar based reader is presented in [30], which interrogates a chipless tag with a UWB pulse and analyses received backscatter in the time domain to obtain the IDs. A chipless RFID transponder based on phase encoded backscatter is proposed in [31], which comprises 3 microstrip patch antennas loaded with open circuited high impedance stubs. The antennas re-radiate backscattered signals with distinct phase characteristics that are encoded as hexadecimal bits for the proposed chipless RFID tag.…”

The Radio Frequency Identification (RFID) technology has gained interests in both academia and industry since its invention. In addition to the applications in access control and supply chain, RFID is also a cost-efficient solution for Non-Destructive Testing (NDT) and pervasive monitoring. The battery free RFID tags are used as independent electromagnetic sensors or energy harvesting and data transmission interface of sensor modules for different measurement purposes. This review paper aims to provide a comprehensive overview of the innovative designs and applications of RFID sensor technology with new insights, identify the technical challenges, and outline the future perspectives. With a brief introduction to the fundamentals of RFID measurement, the enabling technologies and recent technical progress are illustrated, followed by an extensive discussion of the novel designs and applications. Then, based on an in-depth analysis, the potential constraints are identified and the envisaged future directions are suggested, including printable/wearable RFID, System-on-Chip (SoC), ultra-low power, etc. The comprehensive discussion of RFID sensor technology will be inspirational and useful for academic and industrial communities in investigating, developing, and applying RFID for various measurement applications.

“…This task obviously presents different challenges that have been faced in the last years by original approaches to the exploitation of different EM signature strategies for encoding the information. For example, the ID has been stored in the frequency response of the tag [16,17], as well as in the timing of the response [18,19],and also by exploiting the phase [20,21] or the polarization [22,23] of the scattered field. Moreover, a suitably designed chipless RFID can be also employed as a sensor for monitoring quantities, such as humidity [24][25][26], temperature [27], and gas [28], even in harsh environments [29].…”

A novel, chipless, Radio Frequency Identification (RFID) sensor is proposed for monitoring angular rotation. The rotation state is recovered by collecting the cross polar response of a tag, based on a periodic surface composed of a set of dipoles. The encoding mechanism allows the sensor to be very robust, even if it is applied on metallic objects, or in an environment with strong multipath. The proposed sensor does not require a large operational bandwidth. Instead, only a small set of reading frequencies are required. The number of reading frequencies required is dependent on the number of the employed dipoles. It is demonstrated that the rotation state of an object can be monitored within a span of 180 degrees, with up to a three-degree resolution, by employing a chipless RFID sensor comprising of four dipoles. The far field reading scheme and the absence of any electronics device allow the sensor to be employed in harsh environments.

“…Multi-state multi-resonator tags, where more than one bit of information is associated to each resonant element, have been proposed to increase the density of bits per frequency and per surface [36,37]. Another strategy consists of using more than one domain (hybrid tags) [45][46][47][48][49], e.g., encoders based on frequency position and polarization diversity [47], or encoders where frequency domain is combined with phase deviation [46].…”

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

et al. 2017

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.
