Summary: A new method for detecting microwave harmonic Doppler signatures of held objects in cluttered environments is introduced. By combining a passive harmonic tag with a pulsed microwave radar, motion of tagged objects held by a person can be accurately detected with high signal-to-noise ratio and range accuracy. The research presents a new derivation of dynamic harmonic signal response based on truncated Bessel function expansion, and successfully matches the experimental measurements with simulated results.

Summary: This study presents a design for frequency-selective radio frequency (RF) harmonic tags for harmonic Doppler radar tracking. The tags receive incident microwave signals and retransmit a second harmonic signal, making it easier to detect compared to the fundamental frequency. The proposed approach utilizes frequency selectivity implemented by the tag antenna, eliminating the need for additional circuitry to differentiate multiple tags within the same field of view.

Summary: In this study, papers for thermal transfer printing of UHF RFID antennas were prepared by coating and calendering. The impedance of the UHF RFID antennas depended on their design, coating composition, and calendering conditions. Passive UHF RFID tags had approximately the same impedance in the 860-960 MHz frequency band. The communication quality of passive UHF RFID tags was evaluated by measuring the reading range, showing that experimental UHF RFID tags performed similarly to commercial ones at 860 MHz frequency.

Summary: This article presents an ink-jet printed ultrahigh-frequency (UHF) radio frequency identification (RFID) label for tagging fruits. The proposed tag antenna is based on a hybrid configuration, which consists of a loop, dipole-like strips (DLSs), and eye-shaped rectangular nested slots. The loop fulfills impedance matching proposes, while the eye-shaped slots assist to maintain high imaginary impedance to mitigate capacitive effects of high permittivity surfaces of fruits. The fabricated prototype of the proposed tag antenna achieved a read range of 3 m after mounting on apple. Moreover, the tag antenna is also tested for sensing spoilage of apple fruits.

Summary: The CRADLE system utilizes combined RF and acoustic detection and localization for remote parametric ranging of passive tags. By transmitting both RF and ultrasound waves into a region of interest to search for tags, and localizing the tags based on acoustic time of flight, the system can achieve sub-decimeter accuracy at distances up to 6 meters. Future improvements could enable localization of centimeter-sized tags with sub-centimeter accuracy out to several meters.
