Opis:: W artykule zaprezentowano problem syntezy obszaru poprawnej pracy dla propagacyjnych systemów RFID, przy założeniu ich prawidłowego funkcjonowania nie tylko w stanach statycznych (obiekty nieruchome), ale także w trudnych warunkach dynamicznych (obiekty zmieniające swoją lokalizację i orientację w przestrzeni). Dodatkowo wskazano przesłanki, które zapewniają wykorzystywanie obszaru poprawnej pracy jako podstawowego parametru aplikacyjnego systemów RFID.
Nowadays there is often a need to design and implement innovative solutions in Radio Frequency IDentification (RFID). It should be noted that among all factors (Section 1) [4-8] affecting the operation of RFID systems the interrogation zone is the most useful parameter at the design stage [1, 2, 4]. This parameter defines the possibility of using RFID applications for particular automated identification processes. It also comprehensively covers the energy and communication aspects involved with operating of individual components (Fig. 1). At the present state of knowledge the lack of precise specifications (from manufacturers) of electrical and structural properties of offered elements is the main reason for inhibiting the practical implementation of the anticollision identification process. The ability of the interrogation zone synthesis (Section 2) in the RFID system for particular applications consists in the possibility of using complete base of information and taking into account many variables, such as the system parameters, conditions in which it operates, as well as antenna placement and orientation in space (Figs. 2 and 3). The problem of interrogation zone synthesis for the anticollision UHF RFID systems operating under dynamic conditions is presented in the paper (Section 3). The professional test stand (Figs. 4 and 5) for the model verification was constructed.

Opis:: W artykule zaprezentowano dwie metody wyznaczania czułości chipu identyfikatora funkcjonującego w propagacyjnych systemach RFID pasma UHF. Czułość jest reprezentowana przez minimalną moc, która zapewnia prawidłowe działanie identyfikatora w systemie. Parametr ten stanowi podstawę dla syntezy trójwymiarowego obszaru poprawnej pracy w wielokrotnych systemach RFID, przy założeniu ich prawidłowego funkcjonowania nie tylko w stanach statycznych, ale także w trudnych warunkach dynamicznych.
Nowadays there is often a need to implement innovative solutions in Radio Frequency IDentification (RFID) which relate to different economic and public activity (in industry, commerce, science, medicine and others) [1-3]. It should be noted that among all factors affecting the operation of RFID systems, the interrogation zone is the most useful parameter at the design stage (Section 1). This parameter defines the possibility of using RFID system applications in automated identification processes [1, 4]. It also comprehensively covers the energy and communication aspects involved with operation of individual devices of the RFID system (Fig. 1). However, the power supply conditions of passive transponders are critical when the interrogation zone is calculated [5]. Two methods for determination of the chip sensitivity of a transponder working in RFID systems of UHF band are presented in this paper (Section 2). The sensitivity is represented by the minimal power (2), which ensures proper operation of the transponder in the RFID system. This parameter is the basis for synthesis of the 3D interrogation zone for anticollision UHF RFID systems operating in static (fixed location and orientation of objects in space) or dynamic state (objects changing their location and orientation in space). The professional test stand for verification of the sensitivity determination has been also constructed (Section 3).

Opis:: The operation of an anti-collision RFID system is characterized by the interrogation zone which should be estimated in any direction of 3D space for a group of electronic transponders. The interrogation zone should be as large as possible. However, the many problems in this area are due to the fact that energy can be transferred to transponders only on a limited distance. The greatest flexibility in developing RFID applications and shaping the interrogation zone can be achieved using the system with an antenna multiplexer. Therefore the problem of the interrogation zone determination in HF RFID systems with two orthogonal RWD antennas is presented in the paper. The perceived issues have been effectively dealt with and the solution has been proposed on the basis of the elaborated model. Conducted studies have been used to develop the software tool JankoRFIDmuxHF in the Mathcad environment. The research results are analysed in an example system configuration. The specialized measuring stand has been used for experimental verification of the identification efficiency. The convergence of the measurements and calculations confirms a practical usefulness of the presented concept of interrogation zone determination in anti-collision systems. It also shows the practical utility of the developed model and software tools.

Opis:: The new numerical model of directional radiation pattern, in which part of energy is emitted in side and back lobs, has been presented in this paper. The model input values are determined on the base of primary parameters that can be read from the datasheet of used antennas. The special software tool NmAntPat has been elaborated to carry out the described task. The elaborated model, program and output files can be easily implemented into an analysis of radio wave propagation phenomenon in any algorithms and numerical calculations. The comparison of the graphical plots that have been obtained on the base of measurements, producers’ data specification notes and modelling results confirms the model correctness.

Opis:: The interrogation zone IZ is the most important parameter when RFID systems are considered. Its predictability is determined by the construction and parameters of antenna built in a read/write device. The IZ should be of sufficient size and appropriate to requirements established for an application of object automated identification. The method of shaping an antenna radiation pattern provides effective yet unconventional opportunities in this area. The idea and practical solution of the phased antenna array dedicated to UHF read/write devices are presented in the paper. On the basis of tests carried out, the authors pointed out the possibility of using developed devices for the synthesis of a determined IZ in anti-collision RFID system.

Opis:: The authors paid particular attention to the problem of antenna impedance measurements in the RFID technique. These measurements have to be realized by using two ports of a vector network analyzer and dedicated passive differential probes. Since the measurement process and estimated parameters depend on the frequency band, operating conditions, type of the system component and antenna designs used, appropriate verification of the impedance parameters on the basis of properly conducted experiments is a crucial stage in the antenna synthesis of transponders and read/write devices. Accordingly, a systematized procedure of impedance measurements is proposed. It can be easily implemented by designers preparing antennas for different kinds of RFID applications. The essence of indirect measurements of the differential impedance parameters is discussed in details. The experimental verification has been made on the basis of a few representative examples.

Opis:: W artykule zaprezentowano konstrukcję i wykorzystanie stanowiska dedykowanego do pomiarów parametrów procesu automatycznej identyfikacji RFID w warunkach dynamicznych. Podstawowym jego elementem jest opracowany pozycjoner 3D, którego konstrukcja zapewnia weryfikację funkcjonowania pojedynczego lub wielokrotnego systemu RFID. Użyteczność stanowiska zobrazowano na przykładzie modelu zmiennej orientacji identyfikatorów, wykorzystywanego podczas wyznaczania obszaru poprawnej pracy indukcyjnie sprzężonego systemu RFID. Szczególną uwagę zwrócono na problem prawidłowego zasilania identyfikatorów pasywnych.
The correct preparation of model for bilateral interaction between objects during their dynamic changes of mutual orientation in space is usually crucial to the accurate operating of a future system in real environment [1, 2]. This type of two-sided relation between elements is also the basis for operation of the Radio Frequency IDentification (RFID) systems for labelling objects (Section 1). The main parameter determining the quality of the interaction between Read/Write Device (RWD) and an identifier (transponder) is described as an interrogation zone [3]. The need for the proposed model (Figs. 1-3 - detailed described in Section 2) verification was the inspiration for developing a special measuring stand. The designed and constructed structure of a two-axle positioner (Fig. 4) is presented in the paper (Section 3). This unit is the main component of the stand (Fig. 5) and allows any change of spatial orientation according to the elements of RFID system. Furthermore, in accordance with the project assumption, an impact of its parts on the magnetic field generated by the RWD antenna is negligible. Its spatial and time parameters are fully controlled by the dedicated software application (Fig. 5a). An integration of the positioner with specialized equipment of RFID technology laboratory in Rzeszów University of Technology allows measuring the impact of dynamicchanges in the position of a few identifiers on the parameters of the anticollision identification process for labelled objects [6].

Opis:: The idea of multiband development board designed to support and advance the technique of battery-less autonomous semi-passive RFID transponders is presented in the paper. The extra function of harvesting energy from the electromagnetic field of different radio communications systems, the ultra efficient power conditioner and the energy storage block are applied in the proposed construction. The facility of utilizing gathered energy is provided to support designers in developing applications of automatic object identification. Since the evaluation board is to work without a galvanic cell, the particular emphasis is put on the mechanisms that improve energy efficient operation of the whole electronic circuit. The construction principles and operation modes (charging, cold start, sleep with charging, sleep, measurement and cut-off) of the storage unit are described in depth in the paper. The preproduction batch of the demonstrators has been manufactured on automated assembly line at ELMAK Ltd. Company, according to the elaborated model. It confirms that the author’s demonstrator of the battery-less autonomous semi-passive transponder can be reproduced on an industrial scale. On the basis of the preproduction series, the performance parameters of the final product have been estimated. The presented study should significantly contribute to the RFID technique therefore the authors set up the evaluation process of marketing research and product commercialization.
