Summary: In this article, a compact chipless RFID tag with a small size and high data density is proposed. The tag consists of nested octagonal loops arranged in a concentric configuration and is designed to improve the resonating modes with respect to the number of resonating elements. An 11-bits data capacity is achieved within a physical dimension of 10 x 10 mm(2), resulting in a high data density of 11 b/cm(2). The tag advantages include its compact size, high data density, and improved resonating modes.

Summary: This article introduces a 14-bit chipless RFID label that can be used as a decimal numeric keypad for secure access control applications. The label, made of a low-cost single layer design with 10 RF loop scatterers, codes information in the frequency domain. The resonators are carefully selected to be highly resonant and sensitive to the presence or absence of the human finger, allowing for detection of key pressing events.

Summary: The proposed research introduces a novel chipless RFID tag that is fully passive, data-dense, and compact with a size of 15 x 15 mm(2). This tag has a 15-bit data, allowing for 2(15) unique ID combinations. It achieves a bit density of 6.67 bits/cm(2) due to its data-dense structure. The tag is optimized and analyzed for various flexible laminates including Rogers (RT/duroid®/5880), Kapton® HN, PET, and HP-photopaper, using silver nanoparticle-based conductive tracks for printability. The conductivity of the silver ink used is 9 x 10(6) S/m. The fully printable tag structure, optimized with HP-photopaper substrate and silver nanoparticle-based ink, aligns with the concept of green electronics as it utilizes an organic paper substrate. The tag also exhibits humidity sensing behavior due to the moisture-absorbing nature of paper. With its attractive features such as robustness, flexibility, simple printing, and compatibility with budget-friendly extensible substrates, this tag can be applied in rough environments for sensing purposes.
