Near field communication (NFC) is a subcategory of Radio frequency identification (RFID) that is completely vital as a part of 5G and IoT. The Device-to-Device (D2D) communique, Vehicle-to-Vehicle (V2V) communique, Machine-to-Machine (M2M) communique, and Internet-of-Things (IoT) are the modern-day techniques, which contributes an essential function in present wireless and mobile communique. But the primary hassle for the cutting edge wireless communique system is the ‘steering withinside the layout of ultra-low latency’. Ultra-low latency wireless transmission makes use of asynchronous transmission. Universal Filter Multi-Carrier (UFMC) is a brand new modulation method alongside an advanced filtering wireless mechanism that overcomes this hassle. This paper is provided that the increment withinside the range of sub-bands complements the Bit Error Rate (BER) for UFMC. Here efforts are furnished for the discount withinside the BER through growing SNR.

This paper is based on an experimental setup for RFID tag characterization using an Alien 9900+reader. The first part uses a technique based on the joint acquisition of the tag response versus transmitted power and distance for determining the RSSI (Received Signal Strength Indicator) conversion toward the received power. The second part presents an experiment which illustrates the effect of absorbing panels on the read range. Observations showed that having no absorbing panels improves the read range of the tag. Multipath have been observed being beneficial for the read range.

Radio Frequency (RF) power transfer is an enabling technology of RFID systems. CMOS RF rectifiers enable miniaturization and improved integration with full systems. For certain applications, rectifiers may need to be deployed in high or low temperature environments, which can affect their power conversion efficiency (PCE). This work presents the design of a high efficiency 915 MHz CMOS Dickson charge-pump in a 2S nm FDSOI process, and investigates antenna-based impedance matching as a method of maximizing the PCE for different temperatures and CMOS process variations. With a co-designed antenna, the proposed rectifier achieves $ 5.4times $ higher PCE compared to simple inductive-matching at -20dBm. The PCE is then analyzed for CMOS process and temperature variations. It is shown that the rectifier can maintain 94% of its peak PCE at -15dBm at -10°C through input-impedance matching. The proposed rectifier and matching technique achieves the highest PCE compared to state-of-the-art Dickson multipliers, while having the smallest die area.

A novel localization method is proposed and demonstrated which exploits the phase profile combined with the location of the moving robot to locate target tags using only a single straight-line interrogator antenna trajectory. A system that integrates a mobile robot with an integrated RFID reader and antenna is used to obtain phase measurements of target tags when the robot is moving along its trajectory. The cross-range location of the target is obtained from the stationary point of the fitted phase curve. The down range distance is estimated by finding the integer number of wavelengths which fits the cross-range location and curve shape. The proposed method could reduce the localization error to around 12 cm which is similar to the SAR method using a straight-line trajectory, but with much lower computational complexity.

Commodity passive RFID system has been widely used for sensing, localization, gesture recognition and tracking due to its low cost and ubiquity. However, the orientation of RFID tag’s body to the reader’s directional antenna could significantly affect the sensing performance. In this paper, we will theoretically analyse the impact of orientation in RFID-based sensing. Then, we will propose a signal ratio based algorithm to mitigate the impact of orientation in RFID-based sensing.

In this paper, two array configurations of chipless RFID sensor tags are proposed for the detection of crack on a large metallic surface. A single sensor tag contains compass-shaped and a pair of L-shaped resonators. The metallic object under observation is identified by resonant frequencies of L-shaped resonators and crack on metallic object is observed by shift in resonant frequency of compass-shaped resonator. The unit cell tag provides read range of 120 cm and sensitivity of around 75 MHz/mm for 6 cm wide square-shaped surface. However, its performance degrades for larger surface. Therefore, a $3 times 3$ array of sensor tag is proposed for larger surface area. The $3 times 3$ array configuration can detect crack but can’t identify crack location due to the identical elements. To resolve the issue an idea of series array having five rectangular resonators with non-identical dimensions hence multiple resonant frequencies is presented. It helps to identify presence and position of crack on relatively large metallic surface.

Tracking and monitoring workers in large job sites is a difficult job. Therefore, RFID technology may be the solution to reduce down the time to monitor the workers and obtain the related information. UHF RFID technology has the advantage of reading from a farther distance beside the provision to store information about the tagged worker offering a better reliable solution for their traceability and safety. Here, a UHF RFID tag antenna is proposed to develop an “IoT enabled RFID system” for the monitoring of workers. The designed tag has a simple structure and does not require any metallic vias. The proposed tag exhibits a perfect conjugate match to that of the integrated Higgs-4 chip in the European band. The tag is first designed for free space and then optimized to work on a worker’s helmet with a read range of 4.6 meters.

The last two years were strongly shaped by the COVID-19 pandemic and the social distancing countermeasures. The worldwide research changed as well, focusing on the problems created or exacerbated by the novel coronavirus. The Pervasive Electromagnetics Lab of the Tor Vergata University of Rome with a great engagement of several medical engineering students focused on applying sensor-oriented RFID to improve personal safety. In particular, the sensorization of the filtering facepiece respirators (FFRs) was one of the COVID-inspired research topics. FFRs integrating RFID-based sensors were designed and tested. In this contribution, the most significant results achieved are summarized regarding humidity-sensing and cough-monitoring FFRs.
