Summary: In the past decade, IoT technology has made significant advancements in various fields. Intelligent transportation systems (ITS), as a core application of IoT, have gained great attention from researchers. Radio frequency identification (RFID) is an essential technology in IoT and plays a crucial role in identifying tagged vehicles in ITS. However, the existing commercial-off-the-shelf (COTS) RFID tags cannot support the hash function, which poses a challenge for unknown tag identification protocols. To address this issue, we propose two approaches to efficiently identify unknown COTS RFID tags.

Summary: This paper presents the design of an ultra high-frequency (UHF) RFID sensor tag integrated into a textile yarn using E-Thread(R) technology. The temperature detection is based on the change in impedance matching between the tag's antenna and chip, caused by the variation in resistance of a thermistor integrated within the tag system. A differential approach is proposed for environment independent detection, eliminating the need for pre-calibration using a reference tag. Experimental characterization demonstrates the potential of this RFID sensor in detecting temperature variations or thresholds between 25 and 70 degrees Celsius through differential activation power variations.

Summary: The proposed research introduces a novel chipless RFID tag that is fully passive, data-dense, and compact with a size of 15 x 15 mm(2). This tag has a 15-bit data, allowing for 2(15) unique ID combinations. It achieves a bit density of 6.67 bits/cm(2) due to its data-dense structure. The tag is optimized and analyzed for various flexible laminates including Rogers (RT/duroid®/5880), Kapton® HN, PET, and HP-photopaper, using silver nanoparticle-based conductive tracks for printability. The conductivity of the silver ink used is 9 x 10(6) S/m. The fully printable tag structure, optimized with HP-photopaper substrate and silver nanoparticle-based ink, aligns with the concept of green electronics as it utilizes an organic paper substrate. The tag also exhibits humidity sensing behavior due to the moisture-absorbing nature of paper. With its attractive features such as robustness, flexibility, simple printing, and compatibility with budget-friendly extensible substrates, this tag can be applied in rough environments for sensing purposes.

Summary: Synthetic aperture radar (SAR)-based microwave imaging systems are widely used in various applications. The scanning speed is a crucial factor in SAR imaging systems, and widening the distance between measurements can increase it. However, this causes the presence of grating lobes that degrade the quality of microwave SAR images. To address this issue, a novel methodology is proposed in this study, which incorporates the amplitude and phase of the field radiated by the transmitting and receiving antennas in the backpropagation imaging algorithm. This method exploits the directive pattern of the antennas to reduce the level of grating lobes in SAR images.
