RFID SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a high-accuracy RFID system allowing reduction of a size of an antenna portion.

SOLUTION: This RFID system comprises an interrogator and a responder. The responder has: a power source reproduction part for reproducing power of voltage according to reception intensity of an interrogation signal carrier wave on the basis of the carrier wave received from the interrogator; and a response signal carrier wave generation part generating a response signal carrier wave of a frequency according to the voltage by use of the power of the voltage according to the reception intensity reproduced by the power reproduction part.
