Summary: This paper presents a new analog design for a long-read range RFID tag antenna aimed at localization applications. The design focuses on characterizing the antenna impedance through the study of capacitive effects created by gaps and the introduction of open circuited L-shaped stubs. The results show that the proposed antenna design significantly improves performance through the introduction of gaps and stub structures with optimized dimensions. The proposed antenna operates in two frequency bands and is mainly composed of three split rectangular resonators.

Summary: This article addresses the issue of using smartphones to read UHF RFID tags and fetch relevant information. The proposed ShakeReader system allows users to 'read' the interested tags by making predefined gestures in front of them, causing changes in RFID measurement data and motion sensor data. Experimental results demonstrate that ShakeReader can accurately pair interested tags with their corresponding smartphones with an accuracy of >96.3%.

Summary: This work presents a polarization diversity-based rotation sensing methodology using common-off-the-shelf (COTS) UHF RFID tags identified with a software-defined radio (SDR) UHF RFID reader. The proposed methodology utilizes the tag-to-reader message after fully coherent demodulation to calculate a difference signal of the backscatter load modulation states, which is then used to compute the rotation speed by evaluating its phase change over time. Experimental results are provided for validation and evaluation of the system's performance and limitations.

Summary: A novel combination of loop and dipole antennas into a Yagi-like structure is investigated for implementing a wearable antenna. Compact Yagi-like textile structures are designed and compared, with parasitic elements acting as reflectors or directors to limit radiation towards undesired directions. Performance of these structures is measured in terms of reflection coefficient and near-field distribution, with read range performance measured using RFID reader and tags.

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.
