It is computed from the area A bit and the bandwidth fraction B bit needed to realize a single bit on the tag by FoM = 1/(A bit B bit ).…”

This paper introduces three novel passive phase modulators for entirely electromagnetic chipless time domain RFID tags. The modulators overcome limitations of earlier approaches and allow for a highly increased signal space coverage, and, therefore, the implementation of high order PSK or QAM schemes. All three modulators are studied in theory and practically implemented up to a 16-PSK on a reconfigurable prototype tag with 4 modulation stages, realizing a 16 bit information content. Besides showing the measurement results, the assets and drawbacks of the three approaches are carefully compared and the achieved information density is related with approaches from literature.

“…The phase response is exploited in [10], whereas cross-polar components are used in [11] and [12]. Hybrid approaches and other paradigms are illustrated in [13]- [15]. This letter illustrates the design of a chipless RFID tag that encodes the information by discretizing the difference (delta-phase) between the phase of the reflection coefficient for a TE and a TM plane wave incidence.…”

A novel encoding paradigm for chipless radio frequency identification (RFID) tags based on phase quantization is presented. The most distinctive features of this approach are represented by the low requirement on bandwidth and by the encoding scheme. The former is achieved by using only a multifrequency reading without resorting to ultrawideband systems, whereas the latter relies on linking the information to the quantized difference between the TE and TM phase response of the tag. The encoding mechanism is described as well as the decoding procedure. The reliability of the illustrated approach is experimentally validated by measurements on fabricated prototypes

“…These drawbacks limit the application of RFID in harsh environments or cost-sensitive systems. Passive chipless RFID is considered to be a possible complement to fill this gap [2], [3]. This can be achieved by replacing the cost expensive and temperature sensitive microchip of classical RFID applications with a passive modulation circuitry consisting of resonators or reflectors.…”

A new concept for implementing delay elements in chipless TDR RFID tags is presented. It is based on filter design techniques and aims for less dispersive and compact designs. Since dispersion has influence on ISI and phase distortion, a reduction of the dispersion leads to an increase in the system's performance and the read range, respectively. This is first analyzed with the help of a system-theoretic simulation. From the filter design methods considered in this paper, the Butterworth method shows to be best suited for this purpose. An adaption of the Butterworth filter design regarding group delay design requirements is derived. A filter design is carried out and a delay section with low group delay dispersion is implemented. Finally, a prototype tag is realized and measured to verify the applicability of the designed filter-based slow wave structure for chipless TDR RFID tags.
