Abstract
The importance of the radio-frequency identification (RFID) technology and photovoltaic (PV) systems has been growing systematically in the modern world full of intelligent products connected to the Internet. Monitoring parameters of green energy plants is a crucial issue for efficient conversion of solar radiation, and cheap RFID transponders/sensors can be involved in this process to provide better performance of module supervision in scattered installations. Since many components of PV panels disturb the radio-wave propagation, research in the antenna scope has to be carried out to reach the proposed fusion. The problem with RFID transponders being detuned in close proximity to glass or metal surfaces can be solved on the basis of solutions known from the scientific literature. The authors went further, revealing a new antenna construction that can be fabricated straight on a cover glass of the PV panels. To achieve the established task, they incorporated advantages from the latest advancements in materials technology and low-power electronics and from the progress in understanding radio-wave propagation phenomena. The numerical model of the antenna was elaborated in the Hyper Lynx 3D EM software environment, and test samples were fabricated on the technology line of ML System Company. The convergence of calculated and measured antenna parameters confirms the design correctness. Thus, the studied antenna can be used to elaborate the cheap semipassive RFID transponders/sensors in the PV panel production lines.
Highlights
The radio frequency identification (RFID) technology is often used in automated processes in various areas of human socioeconomic activity [1]
RFID devices are increasingly used in sectors such as security and access control systems, logistics, trade in fast-moving consumer goods (FMCG), research experimental samples and valuable materials in the world supply chains [5]
Important applications can be found in the automatic vehicle identification (AVI) area, including reliable and safe object identification in rail or road transport along with the tracking and navigation of moving vehicles [6]
Summary
The radio frequency identification (RFID) technology is often used in automated processes in various areas of human socioeconomic activity [1]. It should be noted that the RFID technology is becoming more and more common in distributed sensor networks, in which it is used to monitor operation parameters of various types of installations. Micromachines 2020, 11, 420 of the chip is keying This method of passing signal back to the interrogator is called the backscattering. This property allows to distinguish the RFID transponders from well-known short-range devices (SRDs) [19]
