<P>PROBLEM TO BE SOLVED: To provide a position detection system for detecting the position of an ID tag reader more accurately by aligning the polarization surface of the linearly polarized antenna of the ID tag reader to that of the linearly polarized antenna of each ID tag when reading an ID. <P>SOLUTION: The position detection system 1 reads an ID transmitted from the ID tag 10 having the linearly polarized antenna 10a by the ID tag reader 20 having the linearly polarized antenna 20a, and detects the position of the ID tag reader 20 by a position detector 30, based on the read ID. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
