<p><P>PROBLEM TO BE SOLVED: To provide an antenna capable of making normal communication with a wireless IC tag even when a face of an antenna of the wireless IC tag attached to an object faces any direction in three-dimensional directions. <P>SOLUTION: The loop antenna (2) is used for a reader/writer for making communication with a wireless IC tag (4) to read information of the wireless IC tag (4) and to write information to the wireless IC tag (4). Both ends of an 8-shaped antenna wire (5) of the loop antenna (2) remotest from its crossing part (6) are located in parallel, electromagnetically coupled (13) with each other and formed to be a loop, the inside of the loop is formed for a space through which the wireless IC tag passes. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
