“…The labels have the capability to store useful information for customers related to the fruit's farm location, picking date, price, expiry, and other useful data. Sharif et al (2019d) successfully tested RFID sensors for salinity-sugar contents of water by measuring the backscattered power mechanism. This research paves the path for portable device-based liquid analysis, which is beneficial for healthcare applications in future IoT.…”

Radio frequency identification (RFID) is a pivotal technology to realize the Internet of Things (IoT) dreams and considered as a last-mile solution. Therefore, this paper presents a novel compact antenna design for UHF RFID handset with angle-adjustable linear polarization using characteristic mode analysis. The proposed antenna design consists of a multi-orientation dipole partially printed on three sides of C shaped F4B substrate and an internal ground behind the handset screen. First of all, different characteristic modes of multi-orientation dipole and ground plane are analyzed using characteristic mode analysis, which shows that the vertical polarization is provided by ground plane, and the horizontal polarization is produced by the dipole. Secondly, the proposed multi-orientation dipole is connected with internal ground using two metal shorting strips to adjust the polarization angle. Finally, a suitable feeding position is selected to excite the required characteristic modes to get the radiation pattern with slant polarization. This antenna covers whole US UHF RFID band ranging from 902-928 MHz. The advantage behind slant polarization lies in reading of RFID tags with both horizontal and vertical orientations. A prototype of antenna with 45-degree linear polarization angle is fabricated to prove the concept, and the measurement results are matched well with simulated results. Furthermore, this paper paves the way to use typical android phone-sized handheld reader as terminal device for future IoT applications ranging from consumer terminal devices to infotainment solutions by providing capability of reading RFID tag with different orientations. INDEX TERMS Characteristic mode theory, angle-adjustable linear polarization radiation pattern, and UHF RFID handset.

“…For instance, some tag antennas incorporating a nested slot feed were proposed in Refs. [10,[22][23][24][25][26][27][28][29][30][31][32][33] to improve impedance matching, however, offering a read range of ~2.5 m. The nested slot technique showed large dimensions [24], with adverse effects in close proximity of water. Similarly, a conformal tag antenna with a reading range of 3.5 m [34,35] was proposed for a smart blood repository system to track blood bags [36].…”

A compact, flexible, long-range, and impedance transformer balun-like integrated UHF RFID tag antenna is proposed for the detection of water bottles. To alleviate the performance of a tag antenna in close proximity to a high dielectric material such as water, the radiating element of the tag antenna uses folded, unbalanced strips made of balun-like arms wrapped around the tag's body. As a result, a wide bandwidth with reasonably good radiation resistance is achieved. The tag's body comprises dual-loops for the impedance matching to the tag chip. This leads to a long read range of 13.33 m; > 5.83 m compared to other state-of-the-art designs. The proposed tag antenna conforms to a small footprint by wrapping the balun-like arms around the tag's body, which results in a compact form. The tag is fabricated, and the results reasonably agree with simulations.
