“…In [28], high-capacity combshaped tags are presented. Frequency-domain-based high-capacity tags were recently presented [29] having a closed-loop structure and [30] a 32-bit single quadrant anglecontrolled tag. In [31,32], a novel design methodology to design CRFID tags via systematic loading of a square split ring with circular and square slots are presented.…”

This paper presents a unique geometry of a chipless radio frequency identification (RFID) tag for encoding a large number of bits in a very small form factor. The tag geometry consists of semi-octagonal copper strips, sequentially laid on a single side of an ultra-thin substrate. A unique and robust encoding mechanism for the tag identification (ID) is proposed. The operating frequency spectrum of the tag ranges from 3.1 to 10.5 GHz. The tag is compact, having an overall size of 14.5 × 28 mm2. The proposed tag exhibits very high code density of 9.85 bits/cm2 and spectral efficiency of 5.4 bits/GHz. The unique geometric configuration of the proposed tag allows it to encode up to 40 bits of data as an RCS signature. This chipless RFID tag seems to be a potential candidate for a wide range of modern RFID applications.

“…This also leads to high code densities, which depends upon the physical configuration and size of the tag in question. The EM signatures of these tags are measured as radar cross section (RCS) and EM resonances present in the RCS are used to decode the encoded information [18].…”

In this paper, a unique structural design methodology for chipless radio-frequency identification (RFID) tags in frequency domain is presented. The tag geometry is developed by loading an open-loop resonator with micro-metallic-cells (MMC). The realization give rise to a checkerboard resonator type with electromagnetic signatures in its radar cross section that are extremely efficient to manipulate. The resonators layout is distributed on either side of a Rogers substrate to double its coding density. The proposed chipless RFID tag has a memory of 8-bits in total. The operating band of the tag is 6.5-10.5 GHz. The tag has a high bit coding density of 10.94 bits/cm 2 and spectral efficiency of 2 bits/GHz. The tag has a very compact size of 17.4 × 4.2 mm 2 . The simple structuring methodology and efficient resonators layout will give RFID system designers the flexibility to apply the proposed tag in a wide range of modern applications.INDEX TERMS Chipless radio frequency identification (CRFID), frequency-domain (FD), miniaturization, open-loop, radar cross section (RCS), resonators, tag.

“…In these types of tags, information is encoded using the FD technique, where the presence and absence of the resonant peaks are encoded as '1' and '0', respectively. In another method presented in [8], open stub resonators are used to design chipless tags. In [9,10], the TD technique was used to encode the data by using the reflected signal from discontinuities placed at specified locations in the structure.…”

This paper presents a novel methodology for designing high-capacity frequency domain chipless RFID tags based on the backscattering principle. The tag consists of multiple square open-loop resonators loaded with a varying number of square metallic patches to form a mesh structure. Thus, in contrast to conventional designs, the overall physical size of each resonator remains fixed and does not change with respect to its operating resonant frequency. The RCS response of the proposed tag can be easily manipulated by varying the loading factor of each resonator. The tag size is further miniaturized by placing resonators on both sides of the substrate used. The tag configuration with resonators arranged in the form of a single row (4 × 1) printed on both sides of the substrate is finally chosen for maximum robustness and efficiency. The frequency shift coding (FSC) technique is used to encode more than one bit per resonator by using segments within sub-bands. The proposed tag encodes 16-bit data in a frequency band from 5.9 to 10.5 GHz and has a very high code density of 23.51 bits/cm2 and a spectral efficiency of 3.47 bits/GHz. The design methodology is novel and leads to a very efficient chipless RFID tag that can be used in a variety of high-data-capacity applications.
