<p><P>PROBLEM TO BE SOLVED: To provide an RFID reader/writer where resonance frequency is adjusted with great accuracy. <P>SOLUTION: The RFID reader/writer 100 divides a resonance frequency adjustment capacitor into at least a first resonance frequency adjustment capacitor C3 and a second resonance frequency adjustment capacitor C4 in parallel, the first resonance frequency adjustment capacitor C3 is incorporated in an RFID reader/writer module 2, and the second resonance frequency adjustment capacitor C4 is placed outside the RFID reader/writer module 2, so that the capacitance value of the first resonance frequency adjustment capacitor C3 is larger than that of the second resonance frequency adjustment capacitor C4. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
