Octagonal Shaped Flexible Chipless RFID Tag for Internet of Things

Design of A 20-Bit Chipless RFID Tag Utilizing Multiple Resonators in UWB Frequency Range

“…The PET substrate, as shown in Figure 4 provides an additional feature of flexibility [8]. The PET substrate thickness is 0.1 mm, its dielectric constant, 𝜀 𝑟 is 2.9 and its loss tangent value, 𝛿 is 0.0025.…”

“…However, the industry also has a growing interest in developing a tag with no active electronics, like an utterly passive RFID tag. Chipless RFID tag basically requires neither battery nor power source or a silicon chip to capture information wirelessly [8]. Chipless RFID tag is fundamentally a simple passive antenna or resonator.…”

Near Field Rfid Tag for Iot in Sub-Six GHZ Band

“…Modern digital solutions are attempting to complement the traditional security features through embedding RFID tags in official paper-work and banknotes [6][7][8]. On the other hand, wearable RFID tags on flexible substrates have importance in security applications, biomedical applications, structural health monitoring and other logistic applications [9][10][11][12][13][14][15][16][17][18][19][20]. Although traditional RFID systems based on the use of silicon RFID chips are very common and extensively used in practice, some of their limitations, such as cost and robustness, are driving many researches towards alternative solutions, namely chipless RFID.…”

“…The chipless RFID is quite similar in function to the optical bar code, and hence it is also known as RF bar code technology. Chipless RFID system is generally based on multiresonators which perform frequency signature encoding signed in [10][11][12][13][14][15][16][17][18][19][20]. In [11], multiple octagonal shaped resonators are used to present a nine-bit RFID tag on both flexible and non-flexible substrates for Internet of Things (IoT) applications.…”

Depending on the type of the substrate, the range of frequencies was determined.…”
