“…Figure 5 reveals that the proposed structure can work on a broad bandwidth from 860 MHz to 930 MHz, which covers the total band of North America (902-928 MHz) and Europe (865-868 MHz). It is worthwhile to mention that this obtained measured reading range is much higher than the ones previously presented [15,16].…”

Abstract-In this paper, we report a single layer modified T-shaped dipole antenna for UHF-RFID tag applications. The designed RFID tag antenna consists of a pair of T-shaped dipole strips loaded with four half discs patches and a tag chip placed in the center. The antenna's size is 80 × 40 × 1.6 mm 3 . Performance of the proposed design was investigated with simulations and measurements. The main feature of this design is that the RFID tag antenna can operate effectively at 868 MHz and 915 MHz frequency bands which make it broadband. The maximum reading range measured in an anechoic chamber is 4.25 m and 5.27 m at 915 MHz and 867.5 MHz, respectively. Furthermore, the RFID tag antenna can work on metallic plates when inserting a foam spacer between them. The final result has a simple configuration, low profile and can be suitable for practical applications dealing with free-space and metallic objects.

“…For example, one studied the traceability through the food production chain and used equipment to read the tagged items in the supply chain [5,6], where other possible related software architecture was presented in [7]. Later on, different EM issues related to the materials that tags are attached to were preliminarily analyzed for purposes of understanding the influence of material [8], or even approaches to design new tags that should have improved performance if attached to liquids [9]. Deeper evaluation of performance starting from simulations and a radio-link budget point of view was presented in [10], while first-presented empirical evaluation of the commercial reader was given in [11].…”

The Internet of Things (IoT) has a lot to offer and contribute to the retail industry, from the innovations in retail store experience to the increased efficiency in the store management and supply chain optimization. On its way to real-world applications, Radio Frequency IDentification (RFID) became the main enabler for the final IoT deployment. However, to improve the technology performance even further, it is important to overcome the fundamental limitations of its physical layer and, consequently, to better understand how to use the technology in an optimal way. The analysis provided in this paper employs the simulation/measurement study on RFID technology advancement and the influence of radio propagation in a realistic model of the retail environment. The results are provided for different types of the retail layouts and materials that influence tag responsiveness.

“…However, in practice, there are still unresolved issues related to the design of RFID tag antennas in some special environment, such as the identification of liquid-filled bottles. It is crucial to further explore cost-effective RFID tag antenna solutions for liquid-filled bottles [4]. Furthermore, the resonant frequency of the RFID tag antenna may shift significantly in the complicated environment, for example, the presence of other nearby objects, the difference of liquid contents in the bottle or the variation of the bottle shapes.…”

“…In particular, it is challenging to design a high-performance UHF RFID tag antenna suitable for placing on a liquid-filled bottle or container, due to the high conductivity, high relative permittivity (about 80) and the variety of liquids. Although many structures have been proposed [3][4][5], they are still big, inefficient, or not easy to use.…”

It is challenging to design a high-performance UHF RFID tag antenna on a liquid-filled bottle due to the high conductivity, high permittivity, and the variety of liquids. A systematic way how to design a high-performance UHF RFID tag antenna on a liquid-filled bottle is presented. A simple design consisting of a folded dipole and a loop matching structure is first proposed for a tag antenna placed on a water bottle. A co-design approach is adopted to make the water and bottle surface become a part of the tag antenna to eliminate the significant influence of the environment. The measurement results at 915 MHz show that the reading range of the simple design can reach 8 m in the absence of the water bottle and reach 4.2 m when it is placed on a water bottle. The folded dipole on the water bottle is then optimized to improve the gain significantly, and a maximum gain of −5.54 dBi is achieved at 915 MHz. Furthermore, the impedance bandwidth for the tag antenna on the water bottle is greatly improved by increasing the number of loops in the impedance matching structure from one to three, and the −6 dB impedance bandwidth of over 100 MHz (simulation) or 84 MHz (experiment) is achieved. A reading range of 5.6 m is achieved when the tag antenna is placed on a water bottle at 915 MHz.
