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 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:
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.
