Characterization of double directional RFID in an indoor environment with human body

Radio frequency identification (RFID) system has the significant advantage that is capability in reading data correctly and readily without contacting the object surface. Moreover, it can communicate in several mediums and can detect data in unsuitable environment such as more humidity and more vibrating. From these advantages, RFID is bring to apply on daily activities in present moment [1]. The interesting issue is implementation of RFID technology on human body to locate the position and to identify the person. Because the population has grown rapidly, it necessary to separate the detail from each person. To make usage comfortable in communication, RFID system is the best suitable choice to be suitable in identifying and locating human body. This paper introduces the concept of measuring double directional channels in RFID systems. Antennas independent channel data were derived by doing the measurements. The data was useful for investigating the impact of RFID antennas and analyzing signal distortion.
