To fulfill this requirement, an RF-based wireless power transfer (WPT) technique is used at the IoTSN, and an uncrewed aerial vehicle (UAV)-based access point (AP) is utilized to provide the necessary RF power. In particular, a simultaneous wireless information and power transfer (SWIPT) transmitter technique (<inline-formula> <tex-math>$T_{x}$ </tex-math></inline-formula>) is used at the AP, where WPT is used to wirelessly energize the IoTSN. while wireless information transfer (WIT) is used to collect sensor data from the IoTSN. The conventional <inline-formula> <tex-math>$T{x}$ </tex-math></inline-formula> systems are designed for only communication applications. In contrast, in this study, the simulation and measurement results demonstrate that the proposed <inline-formula> <tex-math>$T_{x}$ </tex-math></inline-formula> system achieves SWIPT operation with a latency of 10 seconds at a distance of 16 meters in a real environment. The system uses a relay-controlled battery power operation to make it more energy-efficient, resulting in a 449.24% increase in operational lifetime, thereby making it suitable for UAV-based BLE-IoTSN applications in harsh environments.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"10 ","pages":"188-198"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147558062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reflectarray’s unit cell (UC) employs a metallic resonant patch embedded in the printed dielectric material. By adjusting the vertical position of the patch, different electromagnetic wave reflection paths are obtained. This provides an additional degree of freedom for phase shifting. Specifically, phase shifting in the K-band relies entirely on the different lengths of reflection paths. In contrast, the D-band phase-shifting depends on metallic resonant patches with varied sizes and the different lengths of reflection paths. This unique configuration effectively avoids the coupling issues that challenge conventional dual-band reflectarrays. Besides, the period of the UC can be sufficiently small at K-band (only 0.1 free-space wavelengths) to provide good phase correction and a large beam tilting angle. The reflectarray with multiple metal layers is implemented in a single substrate with an ultrathin profile, using the advanced multi-material industrial-level additive manufacturing technique. The reflectarray antenna can be potentially used in base stations for K-band satellite communications (SatComs) and mm-wave point-to-point beyond 5G communications simultaneously.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"10 ","pages":"262-270"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These incidents pose serious risks to society, resulting in adverse effects and significant harm. Radio frequency (RF) fingerprinting technology offers a new approach to wireless network security. RF fingerprints are based on the physical level of the device and cannot be easily changed. Even devices produced from the same batch have subtle differences. This paper proposes a unique identity feature detection and identification method of RF signal unaffected by complex environment. Based on distributed electromagnetic spectrum system, I/Q data of target signal is acquired. The I/Q distance-received signal strength (RSS) characteristic curve is obtained by processing and further processed to obtain the characteristic parameters. After the features of the target radio device are extracted, they are stored in the RF fingerprint database. Feature identification is achieved by comparing the newly extracted features with those already present in the database. Finally, the target signal is marked according to the feature. The experiments verify that the method has good environmental invariance and discrimination. This allows for direct association between a detected signal and its stored fingerprint.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"10 ","pages":"271-286"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each harvesting path is interfaced with an ultra-low-voltage step-up DC–DC converter configured to provide a regulated 3.7 V output and charge supercapacitors for energy storage. The TEG path directly processes millivolt-level DC output, while the PEG path incorporates voltage step-up, full-wave rectification using low-forward-voltage Schottky diodes, and multi-stage LC filtering to condition low-frequency AC signals before conversion. Experimental evaluation under realistic wearable conditions demonstrates that typical human activity can generate usable energy: the PEG generated <inline-formula> <tex-math>$2.9~mu $ </tex-math></inline-formula>W during routine seated office activities, whereas the TEG generated <inline-formula> <tex-math>$310~mu $ </tex-math></inline-formula>W under the same conditions. Start-up analysis indicates that the converter can operate from inputs as low as 20 mV, although higher input levels significantly reduce activation time and improve stability. The results confirm the complementary behaviour of the two sources, PEG providing higher instantaneous power during active motion and TEG supplying continuous low-level energy during stationary periods, thereby mitigating intermittency and enhancing overall system reliability. The proposed hybrid architecture demonstrates the feasibility of self-powered wearable systems under practical human activity scenarios.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"10 ","pages":"243-253"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed sensor employs a splitter/combiner-based feeding network with differential ring resonator architecture to compensate for environmental effects. The sensitivity is enhanced by integrating an interdigital capacitor (IDC) within the sensitive split region of the resonators. The sensor is experimentally validated for sensing thin solid materials with variable thicknesses, and different concentrations of ethanol and methanol solutions. In solid sensing, the maximum differential resonant frequency shift is 236 MHz for a 0.5 mm thick CA sample. In liquid sensing, a total differential resonant frequency shift of 270 MHz for ethanol and 106 MHz for methanol is achieved over the full 0 to 100% concentration range. A thermal stability study shows that the differential sensing scheme exhibits strong immunity to environmental temperature variations, maintaining a constant differential resonant frequency of 246.25 MHz in response to temperature change. In addition, a controlled biodegradability study of the CA substrate shows maximum weight losses of 17.8% and 40.1% for thick and thin samples, respectively.

An asymmetry in the transponder array is intended to support wireless power transfer (WPT) by focusing the incoming wave onto one rectifier to maximize its efficiency. In this study we use a commercially available integrated circuit (IC) for UHF RFID transponders making the constructed retrodirective transponder compatible with the EPC Gen2 protocol.
