“…Furthermore, the low hardware cost of the decoder could be applied to wireless sensor networks (WSNs), where the energy saving is a crucial design issue, not only for tags but also for readers, as in space applications [24,25].…”

Low complexity and efficient algorithms for Radio-Frequency Identification (RFID) are crucial to foster low-cost and energy-saving solutions. With the aim of lowering the complexity of the radio circuitry, and inspired by the superposition codes concept, we propose a novel encoding algorithm for tag-to-reader communication channels of modern RFID systems. We show that the developed scheme-despite the simplicity of its hardware realization-allows a coding gain comparable to the one obtained by the more complex Viterbi decoding of the Miller 4 modulation scheme used in the EPC Generation 2 Class 1 RFID standard. Simulation results prove the effectiveness of the proposed solution for low-cost tags, under different signal-to-noise ratios (SNRs) and interrogation time durations. Although our numerical evaluation mainly focuses on the EPC Generation-2 standard, we believe that the proposed scheme will also be attractive for future Ultra-wideband RFID systems.

“…Its feasibility has been proved by both considering the experimental measurements and the system simulation. It is characterized by an improved size compared to the square shaped chipless tag based on SIW technology proposed in [13]. It offers a numerous encoding states in a reduced surface using the frequency shifting technique from 5.5 to 8 GHz.…”

“…The proposed prototype in [12] is based on three split ring resonators, and it uses the geometrical angle relative to the reference ring resonator to encode data. SIW technology is applied in [13] using rectangular resonant cavity associated to an UWB antenna, as a chipless tag for space applications. Three tuning posts are used to shift frequency from 3.1 to 4.8 GHz.…”

This study presents the design of a compact Radio Frequency Identification chipless tag, with reduced size, important quality factor and improved results. The proposed prototype is based on Substrate Integrated Waveguide technology using the Half-Mode Substrate Integrated Waveguide technique to reduce the tag size by the half and preserve the same response. Further, the operating frequency band is from 5.5 to 8 GHz inside a compact surface of 1.3 × 5.7 cm². The frequency domain approach is adopted based on the frequency shift coding technique. Keywords-Radio frequency identification (RFID); chipless tag; substrate integrated waveguide (SIW); ultra wide band (UWB) I.

“…Further, the UWB antenna, which is the second parts of the tag, is a novel bowtie meander antenna. Also, the encoding principle in [21] and [22] is based respectively on the missing air via in the substrate and the added metalized posts to ensure the shifting encoding. In this paper, we exploit the two techniques at same time, proving that we can find many frequencies and that each frequency defines an encoding state in a reduced sub-band of UWB.…”

“…The proposed chipless RFID tag is based on 3 dipoles like strips which are properly arranged at particular distances. Recently, in [20] and [21], a new concept of design is demonstrated based on the SIW technology. The tag encodes the data by changing the effective permittivity of the substrate integrated resonator which gives a unique frequency signature without any need to increase the tag size.…”
