Analysis and Measurement of the RFID System Adapted for Identification of Moving Objects

A system study of ability of using a commercially available 869 MHz RFID system for identification of moving objects has been performed. The study has been focused on a power budget of received signal levels and on identification of main signal fadings and their quantification. Two types of TAG antennas have been used. Comparisons of their radiation properties when operated in the close vicinity of the human body (or a simple phantom of a human body) have been performed. Suitability of their use is discussed. Results of this study provide deeper insight in the given problem and information in which way the system should be improved in order to comply with the intended purposes
