“…The complex permittivity of the fabric was measured at the frequency of 1 GHz that is close to the operating band of the designed UHF RFID transponder. It was determined in the laboratory stand composed of Compass Technology Epsilometer (Compass Technology Group LLC, Alpharetta, GA, USA) with integrated Copper Mountain R60 1-Port 6 GHz Vector Network Analyzer (Copper Mountain Technologies, New York, NY, USA) [ 56 ]. The relative permittivity is equal ε r = 1.03 and the dielectric loss tg δ = 0.01 at f 0 = 1 GHz (thickness of fabric: 400 µm).…”

In order to respond the growing interest towards radio frequency identification textile transponders, the authors propose a new approach to design radio frequency identification (RFID) devices by introducing the RFIDtex concept. The coupling system of inductive loops is implemented in the textronic structure with the RFID interface in order to split the transponder into two independently manufactured components. Then both modules can be easily integrated into the RFIDtex tag. The presented simulation and measurement results prove the concept of manufacturing a relatively small antenna in the form of a meandered dipole sewn in with a single thread, and further, that can be connected to the RFID chip through the coupling system without galvanic junctions. The achieved parameters clearly indicate that the tag can correctly communicate with the read/write device as well as the coupling between its both parts works properly, and the impedance matching is possible in this case. The possibility of confectioning products with electronic identification tags at the textile factory site and improved resistance to the impact of environmental conditions are the main advantage of the proposed approach to the RFID devices designing. The RFIDtex transponder idea proposed by the authors was restricted in the patent no PL 231291 B1.

“…Any design is a trade-off of these characteristics and must be optimized based on the application of interest. In an RFID-based sensor, usually small size, planar, and high gain antennas are desired to ensure longer read range and lower fabrication cost [ 50 , 51 ].…”

We present a survey on battery-less Radio Frequency Identification (RFID-based wireless sensors that have emerged in the past several years. We discuss the evolution of RFID turning into wireless sensors. Moreover, we talk about different components of these battery-less RFID-based wireless sensors, five main topologies that transform a simple RFID chip into a battery-less wireless sensor, and state-of-the-art implementations of these topologies. In battery-less wireless sensors, the read range is of key importance. Hence, we discuss how each component of the sensor plays its role in determining the read range and how each topology exploits these components to optimize read range, complexity, and/or cost. Additionally, we discuss potential future directions that can help provide improvements in RFID-based wireless sensor technology.

“…Among others, such a structure is susceptible to detuning (e.g., in the vicinity of metal objects), as well as being affected by even relatively small changes in the geometric dimensions of the radiator (e.g., during sample production), reflected in fluctuations of the impedance value, such that impedance matching in the RF front-end is possible in only a narrow frequency band (e.g., 865-868 MHz). On the other hand, the impedance matching loop short-circuits the input terminals of the RF unit for DC current, and blocks transponder activity [14]. However, it is worth paying attention to this construction, because it enables impedance matching of the antenna to the RFID chip over a wide frequency range (e.g., 860-960 MHz), despite its simple structure [13].…”

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.
