This paper summarizes the activities on RFID done during the last 2 years at the University of Cagliari, describing the advancements in the field and the collaborations established with other institutions. In particular, our main recent activities dealing with RFIDs are the following: study and exploit the advantages of SIW technology in the design of wearable RFID tags operating in the European UHF band, aiming for high isolation from the human body and high robustness with respect to the antenna-body distance variation, while maintaining a reasonably small size; overcome the very limited performance of epidermal antennas, due to the presence of the lossy body, which is cause of strong electromagnetic interactions, by using an appropriate configuration to obtain a platform tolerant epidermal antenna; investigate the possibility of designing fully 3D Printable RFID tags effectively using conductive filaments and polylactic acid substrates.

With the promise of the massive deployment of 5G/mm-Wave technologies, low-maintenance and highly scalable wireless systems are desirable to meet the needs of the next generation IoT systems. Mm-Wave backscattering devices present great potential for IoT systems with their compact form factors, minimalist design, and available spectrum. This paper provides a review of the current state-of-the-art in semi-passive RFID/mmID tag technology, non-line-of-sight (NLOS) repeater architecture, and 5G/mm-Wave energy harvesting enabling low-latency wireless communication, precise localization, long-range capabilities, dense wireless sensor networks, and powering these next generation ultra-low-power RFID systems through the 5G wireless power-grid.

This paper presents a fair comparison between the read range of chipless RFID in co-polarization and cross-polarization in real environments. This comparison is a direct consequence of the bound on the read range for the chipless technology presented in [1]. The approach is based on an analytical model and validated by simulations and measurements. Results are mainly function of the considered residual environment. In static environments (such as anechoic chambers), co-polarization offers the highest read range due to the higher Radar Cross-Section (RCS) of the resonators with identical residual environments. However in dynamic environments (which include all real environments), cross-polarization is more robust since, even if resonators RCS is 6 dB lower than co-polarized tags, the associated residual environment is 10 dB lower. Thus read range in cross-polarization outperforms by a factor of 26% the one obtained in co-polarization in almost all real applications.

A miniaturized microstrip fed folded dipole antenna for RFID applications has been proposed. Two RFID resonance frequencies of 2.4 and 5.8 GHz are accommodated by the antenna. The simulated reflection coefficients are −13.4 dB at 2.4 GHz (2.28 to 2.49 GHz) and −38.5 dB at 5.8 GHz (5.4 to 6.6 GHz). The antenna design is simple, and it provides better impedance matching, and constant omnidirectional radiation pattern. The proposed antennas dimensions are optimized to get the best results at the desired band.

In this paper, two-port circular-ring slot resonator antennas are proposed as RFID tag and reader. The scattering parameters are measured by keeping these antennas in two orientations i.e. same orientation and orthogonal in the complete sub-6 GHz band. Formulas are presented for the forward link and backward link to obtain the path loss. In the forward path, the path loss is found from 24.45 dB to 72.64 dB in frequency range 3.5 to 3.75 GHz while for the backward link, it is 21.70 dB to 66.96 dB range in the same frequency band. Orientation sensitivity confirms the reported antennas can be useful up to 30 cm distance in RFID systems for the 5G frequency band.

In this paper a Battery-Assisted Passive (BAP) RFID based-on sensing system is proposed with the goal of backscattering sensor data to a reader in human monitoring activities. A suitable Printed Circuit Board (PCB) has been designed to integrate the sensors, the tag and the antenna. The sensors consist in two accurate units able to return the body temperature and the systolic pulse signals, from which the heart rate has been estimated. For the sake of transmitting the gathered sensor information, a data packet has been arranged and returned to the interrogating reader. The device size has been minimized by adopting an 866 MHz ceramic antenna. A very appreciable working distance between the tag and the reader has been obtained both in case of device worn or not. In addition to the electromagnetic properties, design aspects of sensors, microcontroller, and RFID chip and have been taken into consideration to realize a comfortable device.

This work puts forth elliptical direction of arrival (DoA) estimation and localization, using phase-based, narrowband measurements. The method exploits a multistatic architecture, where illuminating and receiving antennas are placed in the same line, perhaps in sharp contrast to conventional wisdom. Ambiguities inherent in phase measurements are analytically addressed. Experimental results with Gen2 UHF RFID tags show similar performance in terms of DoA estimation compared to the MUSIC algorithm. In terms of localization accuracy, the proposed method outperformed state-of-the-art algorithms in all cases, offering mean absolute localization error as small as 9 cm, at the expense of additional effort for calibration.

In the last several years, wireless Battery Management Systems (BMS) have slowly become a topic of interest from both academia and industry. It came from a necessity derived from the increased production and use in different systems, including electric vehicles. Wireless communication allows for a more flexible and cost-efficient sensor installation in battery packs. However, many wireless technologies, such as those that use the 2.4 GHz frequency band, suffer from interference limitations that need to be addressed. In this paper, we present an alternative approach to communication in BMS that relies on the use of Near Field Communication (NFC) technology for battery sensor readouts. Due to a vital concern over the counterfeited battery pack products, security measures are also considered. To this end, we propose the use of an effective and easy to integrate authentication schema that is supported by dedicated NFC devices. To test the usability of our design, a demonstrator using the targeted devices was implemented and evaluated.
