A Fundamental Study on the Detection of Pedestrians by Radio Frequency Identification

Whereabouts confirmation in the outdoor has become easy by GPS, but it is difficult to use in the room where GPS electric waves do not reach. To confirm whereabouts in the room, the authors are examining the detection system with IC tag. In this research, the position of the antenna and the IC tag was examined to detect the person equiped with IC tag when he is standing, sitting and moving. From the result of the experiment with passive UHF IC tag, it was shown that the detection range was 100cm ups and downs from the antenna, alsoit was understood that the detection probability rises most when installing IC tag in lower limbs. キーワード: RFID,IC タグ,通過検知
