“…Thus, the differential passive probe with signal-to-signal delicate contact tips was used to connect the antenna to the vector network analyzer with two 50 Ω coaxial ports. The measure procedure-described in detail in [9]-constitutes in the S-parameters determination: where Z0 denotes the reference impedance of 50 Ω. The laboratory stand included VNA Keysight PNA-X N5242A and a commercially available probe (Micromanipulator 44-8000-D-NA) which was moved using a manipulator (Micromanipulator model 110) with three-axis direct lead-screw/lead-nut drivers of resolution 2.2 µ m (10 mm max range in each axis).…”

“…In economic terms, this is due to the increasing availability of RFID equipment on the market, especially new constructions of transponders based on intelligent semipassive chips with additional functionalities (such as power harvesting or physical quantity measuring capabilities) [8]. In technical terms, the good forecast in this area in the coming years is due to progress in recognition of the operational principles of RFID devices and the possibilities of determining their parameters [9,10].Regardless of frequency parameters (operating frequency f 0 and frequency band: low (LF), high (HF) or ultrahigh (UHF)), world regulation of the radio-transmissions (e.g., ISO/IEC 15693, 18000-63 [1,11]) and standardized system implementations (e.g., HITAG, MIFARE and ICODE; NXP Semiconductors, Eindhoven, The Netherlands), the read/write device (RWD) and one or several transponders with a unique identification number (UID) attached to identified objects can be always found in every RFID system (Figure 1). Application efficiency in the automatic identification field is mainly described by the three-dimensional interrogation zone (IZ) [12].…”

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.

This article concerns the use of an integrated RFID system with a mobile robot for the navigation and mapping of closed spaces. The architecture of a prototype mobile robot equipped with a set of RFID readers that performs the mapping functions is described. Laboratory tests of the robot have been carried out using a test stand equipped with a grid of appropriately programmed RFID transponders. A simulation model of the effectiveness of transponder reading by the robot has been prepared. The conclusions from measurements and tests are discussed, and methods for improving the solution are proposed.

The problem considered in the paper concerns the synthesis process of antennas for autonomous semi-passive RFID transponder/sensors dedicated to active glazing units. Glazing units are frequently used in modern multi-storey buildings to create amazing facades. When they are integrated with photovoltaic (PV) modules, active units are obtained. It is desirable, mainly for economic reasons and in order to ensure the high efficiency of a micro-photovoltaic power plant, that active glazing units are equipped with a system for monitoring their operating parameters. In connection with this, design problems occur that fall within the fields of sensor technology and radio communications. The main purpose of the presented study was to prepare appropriate input data for design tools used in the synthesis of antenna systems in the UHF band. Many important issues are considered including: proximity to structural elements of the building facade and PV cells, which disturbs the shape of the radiation pattern and affects the impedance parameters of the antenna system; the need to ensure easy integration of the RFID sensor and the specified object, without significant interference in the production of glazing units; appropriate shaping of the radiation pattern in order to enable reading and writing of the RFID tag from both inside and outside the building; impedance matching to the selected RFID chip in the broadest possible frequency range, etc.
