<p><P>PROBLEM TO BE SOLVED: To provide a RFID (Radio Frequency Identification) tag, which is configured so that even when a plurality of RFID tags are closely arranged, the deterioration of communication characteristics by mutual interference between the RFID tags is prevented, and the plurality of closely-arranged RFID tags can be collectively read by a reader. <P>SOLUTION: The RFID tag has: an IC chip 3; a first antenna 1 connected to the IC chip 3; and an impedance matching circuit which performs impedance matching between the IC chip 3 and the first antenna 1. The tag further has a conductor 4 superposed on the impedance matching circuit through an insulator substrate 2 so as to cover the circuit. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
