“…The sensing potential of this tag makes it suitable for use in IVsolution level observations, blood-bags' remote management, and other remote healthcare applications which can greatly reduce the workload of medical staff. Moreover, to track and tag medicines and pills, a spider web-shaped conformal tag is proposed by Sharif et al (2020) that works in the near-field with uniform electrical field characteristics.…”

Recent advancements in radio frequency (RF) sensing technology can be attributed to the development of the Internet of Things (IoT), healthcare, RF-identification, and communication applications. RF sensing is a multidisciplinary research field that requires expertise in computing, electronics, and electromagnetics to cover all system features, including protocol development, antenna design, sensor integration, algorithm formulation, interconnection, data, and analytics. The overarching aim of this work is to present detailed information about RF technologies and their innovations and application diversity from the novel work carried out at CSI Lab 1, together in one platform with an extensive survey. This study presents state-of-the art applications and RF sensing that include W-Fi, radar, and SDR and RFID-based sensing. A comprehensive survey and study of the advantages and limitations of each non-contact technology is discussed. Additionally, open research gaps have been identified as well. Decades of knowledge and experience have been put to use to meet new challenges and demands. The development and study of RF systems, IoT, RFID sensing, and research and deployment activities, are briefly discussed. The emerging research projects with industry, institutional research centers, and academic studies are also addressed. Finally, an outline of identified potential future research areas is provided, emphasizing opportunities and challenges.

“…It is necessary to successfully read valuables goods with 100 % probability such as medicines, and jewelry. However, one of the key technical issues in the design of UHF near-field RFID reader antennas is to generate a sufficiently strong and relatively uniform field distribution [7][8][9][10][11][12] . In addition, low-cost commercial tag antennas are linearly polarized posing orientation sensitivity issues.…”

This paper proposes a nature-inspired spider web-shaped ultra-high frequency (UHF) radio frequency identification (RFID) reader antenna and battery-free sensor-based system for healthcare applications. This antenna design consists of eight concentric decagons of different sizes and five straight microstrip lines that are connected to the ground using 50 Ω resistors from both ends except one microstrip line, which is left for connecting a feeding port. The reader antenna design features fairly strong and uniform electric and magnetic field characteristics. Likewise, it also poses wideband characteristics by covering whole UHF RFID band (860 – 960 MHz) and tag reading volume of 200 × 200 × 20 mm 3. Additionally, it has low gain characteristics, which are necessary for the majority of nearfield applications to prevent the misreading of other tags. Moreover, the symmetric current distribution throughout the structure in this design addresses the orientation sensitivity issues associated with low-cost linearly polarized tag antennas. The measurement results show that the reader antenna can read medicine pills tagged using low-cost passive/battery-free RFID tags, tagged expensive jewelry, intervenes solution, and blood bags positioned in various orientations. As a result, the proposed reader antenna-based system is a strong contender for near-field RFID, healthcare, and IoT applications.
