“…It is also observed that the quality factor of passive components which are realized on organic substrates is comparatively low [13], but these tags provide other numerous advantages which are incomparable. These advantages include recycling, environmental friendly, low-cost, easy availability and light weight nature of these tags.…”

A compact 16-bit chipless RFID moisture sensor tag with a size of 13.2 × 19.6 mm 2 is designed, fabricated and analyzed. The presented moisture sensor tag is realized on a paper substrate with silver nano particle based ink patches as conducting material. The frequency band of operation is 0.5 to 14 GHz having an overall bandwidth of 13.5 GHz. It is loaded with slots of different lengths and widths, etched on the conductive material. The tag exhibits stable sensing characteristic towards moisture in the real environment. The flexible, sensitive and environmental friendly nature of the proposed tag makes it suitable for wider, low-cost and organic electronics applications.

“…Radio-frequency spectrum is used to transmit the encoded information. The communication is carried out between tag (RFID) and reader (RFID), where the tag is responsible for encoding the data and thus the encoded data is identified by RFID reader [7]. The encoded information is based on frequency signature and hence, each tag has unique tag ID.…”

In this paper chipless RFID tag, capable of carrying 9-bit data is presented. The tag is optimized for several flexible substrates. With growing information and communication technology, sensor integration with data transmission has gained significant attention. Therefore, the tag with the same dimension is then optimized using paper substrate. For different values of permittivity, the relative humidity is observed. Hence, besides carrying information bits, the tag is capable of monitoring and sensing the humidity. The overall dimension of the tag comprising of 9 ring slot resonators is 7 mm. Due to its optimization on the paper substrate, the tag can be an ideal choice for deploying in various low-cost sensing applications.

“…It is experimentally analysed using climate chamber by Weiss Technik WK11-180. 30 The sensing characteristics are scrutinized by implementing diverse levels of moisture in the chamber. The Figure 10 shows that for every 15% increase in the moisture, the RF response of the respective tag shows a subtle drift towards left side, that is, the lower frequencies.…”

A compact 27-bit linearly polarized chipless radio frequency identification tag is presented in this research. The proposed tag is designed with an overall tag dimension of 23 3 23 mm 2 . The tag comprises of metallic (copper) rings-based structure loaded with slots. These slots correspond to a particular sequence of bits. The circular tag is analysed using 2 different substrates, that is, Rogers RT/duroid/5870 and flexible Rogers RT/duroid/5880. The radar cross-section response of frequency signatured tag is analysed for humidity and temperature sensor designs. Humidity sensing is achieved by deploying a DuPont Kapton HN heat resistant sheet on the shortest slot of the tag, that is, the sensing slot. Temperature sensing is attained using Rogers RT/ duroid/5870 and Stanyl polyamide as a combined substrate. Hence, the miniaturized, robust, and flexible tag can be deployed over irregular surfaces for sensing purposes.

It ensures connectivity of physical and virtual objects to the internet at an unprecedented rate, thus, transforming traditional objects into smart ones. 1,2 This technology is an integral part of internet future, and it will interconnect uniquely identified embedded items through ubiquitous communication of physical objects. 3,4 IoT uses wireless and pervasive computing technologies to make objects intelligent. 1,5 The idea of IoT can be implemented using radio frequency identification (RFID) technology. RFID is a promising technology which has revolutionized automatic identification and wireless sensing of tagged objects. 6 RF waves are exchanged between a tag and reader using wireless transmission. RFID is a fairly handy technology because it facilitates non-line of sight communication which improves the tag's efficiency and provides longer reading range. [7][8][9] At the item level tracking, RFID technology is replacing optical barcodes. 7 The fabrication of microchip circuits is really expensive, and this sets a certain limitation on the manufacturing of RFID tags. This problem can be solved by excluding the microchip from the tag design. RFID tag without silicon chip is famous as chipless RFID tag.
