“…For a constant temperature, the read range follows a normal distribution with a sharp peak at the resonant frequency. However, as the temperature increases, the graph is skewed with the same normal distribution with slightly lesser read range values [44][45][46][47][48][49][50][51][52][53][54]. General structure of PTFE sensing antenna is depicted in Figure 6.…”

In this paper, a comprehensive survey on thermal and geometric design parameters of composite materials utilized in the fabrication of modern RFID systems has been discussed mainly due to its advantages such as lightweight and high strength. Designing of RF antenna setup requires careful consideration of material, geometric and fabrication parameters. Polymer materials were chosen as the substrate and subjected to extensive studies to determine and predict the capability of the miniaturized RFID antenna. The effect of the polymer matrix composite (PMC) material on the antenna parameters such as gain, bandwidth, and return loss is analyzed and realized that improvement in bandwidth and perfection in impedance matching can be further accomplished by employing fractal structure. It is also discovered that the thermal properties affect the impedance and operating frequencies, thus enabling multilayer PMC deploying fractal structured RFID antennas to be used for many applications such as logistics, aerospace, biomedical, and mining.

“…With respect to off-the-shelf time-domain readers, high-speed digital oscilloscopes with impulse generators and radar systems have been used [67,170,244,[267][268][269]. The main benefit of using a time-domain reader system is the spreading of the transmitted power over the frequency band of interest with a short single pulse, which provides for high peak power with a low average power.…”

Chipless RFID systems can be considered as a special case of passive RFID systems, where the tag contains no power source and no electronics. Instead, the tag's information is stored in its structure and accessed through its electromagnetic (EM) scattering response. However, robust response detection, which is primarily a function of the measurement method, measurement equipment, and processing method used, is still a major challenge in the chipless RFID field. The consequences of not properly capturing a tag response include, incorrectly assigning an ID or incorrectly reporting a sensing parameter. Due to the criticality of these challenges, this review seeks to provide an overview of the current measurement methods, equipment architectures, and processing methods as they relate to chipless RFID tag response detection and decoding. Since chipless RFID started gaining popularity around 2005, the developments in this area have been focused on three major categories: timedomain, frequency-domain, and spatial-domain systems. Frequency-domain systems have emerged as the most popular among these three categories, and thus, this review focuses on techniques used for these systems.

“…Note that processing multiple RFID tags may cause collision. In such cases, tag-totag anti-collision can be implemented by one of the earlier presented techniques in [36][37][38][39][40][41][42][43]. The remainder of this paper is structured as follows.…”

A Novel Printable Tag of M-Shaped Strips for Chipless Radio-Frequency Identification in IoT Applications

There is a growing interest in chipless radio-frequency identification (RFID) technology for a number of Internet of things (IoT) applications. This is due to its advantages of being of low-cost, low-power, and fully printable. In addition, it enjoys ease of implementation. In this paper, we present a novel, compact, chipless radio-frequency identification (RFID) tag that can be read with either vertical or horizontal polarization within its frequency bandwidth. This increases the sturdiness and detection ability of the RFID system. In addition, the difference between the vertical and horizontal responses can be used for tag identification. The proposed tag uses strip length variations to double the coding capacity and thereby reduce the overall size by almost 50%. It has a coding capacity of 20 bits in the operating bandwidth 3 GHz–7.5 GHz, and its spatial density is approximately 11 bits/cm2. The proposed tag has a 4.44 bits/GHz spectral capacity, 2.44 bits/cm2/GHz encoding capacity, a spatial density at the center frequency of 358.33 bits/λ2, and an encoding capacity at the center frequency of 79.63 bits/λ2/GHz. A prototype is fabricated and experimentally tested at a distance of 10 cm from the RFID reader system. Then, we compare the measured results with the simulations. The simulated results are in reasonable agreement with the simulated ones.
