<p><P>PROBLEM TO BE SOLVED: To provide a position detector which can accurately detects the present position of a moving body, and does not require the registration of information for the detection of a position, a position detecting system, and a radio communication system. <P>SOLUTION: The position detector includes an antenna which is used exclusively for each of a plurality of resonance tags disposed at equal intervals in sequence along a moving path on which a moving body moves so that resonance frequencies of adjacent tags may be different, a resonance tag reading part which reads the resonance tag through each of the antennas, and a position detecting part which detects the position of the moving body based on the number of the resonance tags read by the resonance tag reading part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
