A compact planar tag antenna, which is designed using two closely placed concentric step-impedance rings, is presented for metal-mountable applications in the UHF RFID passband. The tag antenna can be easily constructed using a flexible polyimide and a foam substrate with a dimension of 40 mm $times40$ mm $times3.32$ mm ( $0.122lambda times 0.122lambda times 0.010lambda$ ). Narrowing the line width of the rings are found to be useful for increasing the antenna resistance and reactance, and a conjugate matching condition is achievable between the antenna and the microchip. The proposed tag antenna can read a maximum read distance of $sim 15$ meters with an effective isotropic radiated power of 4 W. In this design, the two intercoupled stepped-impedance rings are cascaded concentrically. An inductive stub is utilized for bringing down the tag resonant frequency. A transmission line model has been constructed to design the tag antenna, and a detailed analysis has been performed to understand the resonance properties. It is important to note that the proposed tag antenna’s operating frequency is stable, and it is not easily altered by the backing metallic object.
本文介绍了一种紧凑型平面标签天线，它采用两个紧密放置的同心阶跃阻抗环设计，适用于超高频 RFID 通带内的金属安装应用。该标签天线可以使用柔性聚酰亚胺和泡沫基板轻松制作，尺寸为 40 毫米（0.122 美元/λ）×40 毫米（0.122 美元/λ）×3.32 美元（0.010 美元/λ）。缩小环的线宽有助于增加天线的电阻和电抗，而且天线和微芯片之间可以实现共轭匹配。在这种设计中，两个相互耦合的阶梯阻抗环是同心级联的。利用电感存根降低标签谐振频率。设计标签天线时构建了一个传输线模型，并进行了详细分析，以了解其谐振特性。值得注意的是，拟议的标签天线工作频率稳定，不易被背衬的金属物体改变。

This work deals with the soil moisture estimation based on received signal strength using low-power LoRa-based soil moisture sensing device. The proposed antenna design is a type of printed inverted F antenna and tuned with a capacitor in the loamy ground with varying properties. The electric field simulation results are given to depict its distribution above the ground with varying moisture content, and the measurements results give the comparison between the proposed printed antenna and the helical LoRA antenna. In the laboratory measurements, it is shown that a difference of approximately 13 dB between the dry and the highest moisture level (40 %) can be achieved in simulations, whereas in measurements, where the signal strength difference is measured from 10 % to 50 %, the difference is 6–7 dB. The proposed antenna tuned in an actual and very lossy soil, achieves very wide bandwidth and consequently less sensitivity to the soil moisture variation. Still it achieves somewhat better results of soil moisture estimation in relation to the conventional helical LoRa antenna. Generally, the results imply that this approach can be most effective in summer period, when smart irrigation is crucial due to droughts, sudden downfalls and the necessity of water consumption management.

The application of animal tracking holds significant importance across diverse economic domains, encompassing sectors including livestock husbandry, agricultural practices, and the conservation of wildlife populations. It aims to track and understand animal behavior, movement patterns, and health status. The predominant use of RFID technology is observed within the domains of logistics, localization, and the tracking of goods. Notably, the application of this technology in the field of animal tracking has experienced a significant surge in popularity in recent years. This paper conducts a systematic literature review focused on understanding how RFID technology is being applied in the field of animal tracking. We have conducted a state-of-the-art research regarding animal tracking solutions in the scientific literature and patents. We have analyzed these solutions targeting which animals are being tracked, which problems are addressed, operating frequency, and whether other technologies are combined with RFID for animal tracking purposes. Among the categories of problems addressed, livestock management emerged as the main area, followed by animal tracking and traceability. Mammals, especially cattle, are the most common type of animal monitored. Considering RFID technology, passive UHF tags appeared more often. Moreover, many works also employed cameras and GPS together with RFID. Finally, this work can significantly contribute to this field by systematically presenting a state-of-the-art application of RFID for animal tracking.

The emerging need for green technologies motivates the development of new approaches to manufacture electronic consumables. In case of low-cost mass-production sensors, the problem becomes even more severe due to the generation of environmental waste. Here we demonstrate an RFID-type sensor based on a caramel substrate with a micron-scale conductive layer. The device, being primarily made of sugar, attracts insects, which consume it almost completely. As an application, we demonstrate a tag that can be applied for remote pest monitoring. In the experiment, a long-range UHF RFID communication channel is established and monitored over time. An RFID-on-caramel tag consumed by insects loses its connection with a reader, indicating the presence of pests. We show the new caramel-based devices to communicate with a reader over a 10-meter distance, paving the way to remote crop monitoring. Such low-cost biodegradable sensors are highly promising for smart agriculture, warehouse management, and stock monitoring approaches.

A new flexible substrate UHF RFID tag on metal with a resonant ring and surface-etched slots that can be read at a long distance is proposed in this paper. The tag has a compact footprint of 50 mm $times50$ mm $times1.1$ mm ( $0.152,,lambda times 0.152,,lambda ,,times 0.003,,lambda $ at 915 MHz). It consists of two rectangular patches with a closed resonant ring and 4 surface etching slots, a narrow inductive stub, and a square ground. With the above structure which can make the tag adjusts both the resistance and reactance of the chip. The antenna has 7 adjustable parameters and can also be resonated at different frequencies. In the simulation, the proposed tag reaches a high power transmission coefficient (99.99%), which is an almost perfect conjugate matching, and the tag can reach a long reading distance of about 11 m on the metal containers. Finally, the tag is fabricated on the flexible polyethylene terephthalate substrates and tested. With an EIRP (effective isotropic radiated power) of 4 W, the tag can be read at a long range of 7.29 meters on metal planes and 3.71 meters on curved metal surfaces.

This paper outlines the components of a digital spectrum twin (DST) and potential application maps that can inform automated or enhanced spectrum management decisions. The DST is fundamentally a map and image database, with environmental, measurement, and prediction maps that allow parallel intelligence operations to generate useful information using aggregating rules that operate on the twin. We demonstrate several application maps generated from measured data collections and propagation modeling associated with the POWDER platform in Salt Lake City, Utah. In total, the methods of this paper provide a blueprint for generating similar DSTs in any other radio bands and regions of the world.

This paper describes an RFID system for head orientation tracking (R-SHOT), a novel wireless and battery-free approach for monitoring head kinematics. R-SHOT uses two linear polarized antennas mounted on a metal frame backpack, three commercial RFID tags placed orthogonally on the subject’s head, an RFID reader, software for data collection and processing, and an IMU for calibration. Training datasets were collected using stationary head positions with varying yaw, pitch, and roll, which were then used to develop a second-order multi-variate model to predict the Euler angles (R2 = 0.997 and standard error = 1–3°). Attempts to use a first-order model, reduce variables, and increase the number of static head positions for model training did not yield favorable results. Challenges in model development due to noise and asynchronous sampling were overcome using a Kalman filter and linear interpolation. The R-SHOT model developed using static head positions was found to predict Euler angles - when applied to full head motion - with low error, especially when the head position was closer to an extreme. The development of this model holds the keys to future real-time application of R-SHOT for patient care and mobility aid solutions.

This paper presents the design and implementation of a wirelessly powered RFID system enclosed inside closely sealed aluminum containers. The system enables power and data transfer to an RFID tag enclosed inside a closely sealed 1 mm thick aluminum container at a distance of up to 1 m from the reader. Utilizing custom-designed magnetic dipoles operating at 103 kHz, the system achieves a maximum harvested power of $408~mu text{W}$ AC and $96~mu text{W}$ DC. Also, bidirectional communication is demonstrated at a maximum data rate of 1.2 kbps. To the best of our knowledge, this is the first demonstration of a passive RFID system operating at a distance of 1 m, while its RFID tag is enclosed inside a closely sealed aluminum container, and without using batteries.

The year 2023 was extremely fruitful for RFID community as it offered a diverse range of perspectives, methodologies, and findings, among all the spectrum of RFID communications and systems. In this context, the IEEE JOURNAL OF RADIO FREQUENCY IDENTIFICATION took the opportunity to gather new florid research contributions in the field of RFID technology in two special issues devoted to hot and cutting-edge research topics: “Augmented RFID sensing systems for environment, healthcare and safety” and “RFID Sensor Fusion for Navigation of Robots and Vehicles”. Sensing capabilities and location-awareness, especially focused to the development of autonomous robots, represent two vital applications for the development of next-generation industrial systems, technologies that serve people and communities. In Fig. 1 it is depicted the output of an online search on the IEEE XPLORE database by selecting only papers published in journals (journals + magazines + early access) from 2015 to 2022, with focus on “RFID Sensing” (blue bars) and “RFID localization” (red bars). There is a clear trend of growth in recent years, which highlights the topicality of the journal proposed special issues in selecting themes of interest to the community.

As a real-time representation of physical entities in the digital world, digital twin (DT) has been widely used in many industrial fields, which has brought remarkable efficiency improvement and cost reduction. With the evolution of 6G network, the requirements for ultra-low delay and intelligence are gradually improved, and digital twin edge network (DTEN) came into being. DTEN mainly collects real-time information of physical objects through edge nodes such as BSs and APs, and builds dynamic models on demand based on these information, which has the ability of description, diagnosis, prediction and decision-making. Aiming at the traffic management and resource allocation in DTEN, a QoE-driven wireless communication resource allocation method based on DTEN is proposed, and the overall architecture design of DTEN system is completed. By integrating DT and RL technologies, the DTEN system models can be self-improved and dynamically adjusted, and the data-driven resource allocation model can be updated efficiently. The simulation results show that the proposed algorithm guarantees a high level of QoE for users. Compared with Q-Learning algorithm alone, the proposed algorithm can support more users’ access under the same congestion performance and reduce the iteration times of the algorithm by about 70%.
