“…Similar to those hairpin resonators discussed above, such implementations could support both OOK and ASK encoding schemes. Interesting implementations of this resonator include that by Nair et al [99], the work of Deng et al [100] and also the tag presented by Sharma et al [101]. Other works of note include the tag developed by Jalaly and Robertson [102], which uses dipole resonators, and the work of Fan et al [103], which uses L-shaped resonators.…”

Chipless Radio Frequency Identification (RFID) has been used in a variety of remote sensing applications and is currently a hot research topic. To date, there have been a large number of chipless RFID tags developed in both academia and in industry that boast a large variation in design characteristics. This review paper sets out to discuss the various design aspects needed in a chipless RFID sensor. Such aspects include: (1) Addressing strategies to allow for unique identification of the tag, (2) Sensing mechanisms used to allow for impedance-based response signal modulation and (3) Sensing materials to introduce the desired impedance change when under the influence of the target stimulus. From the tabular comparison of the various sensing and addressing techniques, it is concluded that although many sensors provide adequate performance characteristics, more work is needed to ensure that this technology is capable/robust enough to operate in many of the applications it has been earmarked for.

“…Several topologies relating to those used based on resonators have been suggested for chipless tags. Such topologies include circular loop [ 20 , 21 , 22 ], square loop [ 23 , 24 , 25 ], U-shaped [ 26 , 27 , 28 ], C-shaped [ 29 , 30 ], L-shaped [ 31 , 32 , 33 , 34 ], slotted [ 34 , 35 , 36 ], rhombic [ 37 , 38 ], octagonal [ 39 ], and microstrip-line [ 18 , 40 , 41 ]. It is also worth noting that the authors have suggested textile wearable application technology devices in the literature [ 42 , 43 ], which can be used as chipless RFID sensor tags in identification and tracking applications.…”

“…Therefore, the degradation of detection performance is quantified. The proposed system does not require calibration tags, and with respect to the reader location, the new approach produces appropriate results under various tag orientations and positions [ 4 , 19 , 34 , 35 , 53 , 54 ].…”

A novel methodology is proposed to reliably predict the resonant characteristics of a multipatch backscatter-based radio frequency identification (RFID) chipless tag. An ultra-wideband impulsion radio (UWB-IR)-based reader interrogates the chipless tag with a UWB pulse, and analyzes the obtained backscatter in the time domain. The RFID system consists of a radar cross-section (RCS)-based chipless tag containing a square microstrip patch antenna array in which the chipless tag is interrogated with a UWB pulse by an UWB-IR-based reader. The main components of the backscattered signal, the structural mode, and the antenna mode were identified and their spectral quality was evaluated. The study revealed that the antenna-mode backscatter includes signal carrying information, while the structural mode backscatter does not include any tag information. The simulation findings were confirmed by experimental measurements obtained in an anechoic chamber environment using a 6-bit multipatch chipless RFID tag. Finally, the novel technique does not use calibration tags and can freely orient tags with respect to the reader.

“…In [12], a single-layer humidity UHF RFID chipless sensor tag is presented along with wired measurements on paper substrate. Table 1 summarizes the state of the art of single-layer chipless RFID tags presenting increase in the coding capacity [14]- [16], orientation independence [14], [17]- [19], size miniaturization [20], dielectric sensing [21], and imaging [22]. However, in most of these works [14]- [22], chipless tags are realized on high-performance expensive copper laminated substrates except in [17], [22], where 3-D printing technology and photolithography are used, respectively.…”

“…This work also studied the effects of variation of the tag-reader orientation (both in E and H planes) on the reading of the proposed tags. Our work can be differentiated from the existing works on slot L-shaped resonators [19], as it is designed on high-performance substrate and measured in co-polarization with two measurements approach. Also, most of the presented analyses (e.g., effects of rotation, metals inks, and direction of tag reading) are based merely on simulations results.…”

Single-Layer, Flexible, and Depolarizing Chipless RFID Tags

This work presents the designs of single-layer chipless radio frequency identification (RFID) tags based on the RF-encoding particles (REP) approach. These tags are the first realized for reading in cross-polarization resulting in a higher immunity against multipath, and thus, achieving robust readings in a practical environment. The proposed chipless tags are of credit-card size, with a frequency band of operation ranging from 3 to 6 GHz within the ultra-wideband (UWB), compliant with low-cost additive fabrication techniques, and realized with low-cost plastic and paper substrates. A study on reader-tag polarization and rotation angle is performed for the proposed designs and compared with the existing designs of two-layers. For the first time, it is presented that the low-cost single-layer tags can be read in realistic environments with only one measurement.
