RFID DEVICE INCLUDING DUAL ANTENNA

摘要

PURPOSE: An RFID device with a dual antenna is provided to include a separate antenna for NF(Near Field) and FF(Far Field) RFID communication in one RFID tag in order to use both two communication methods. CONSTITUTION: A voltage multiplier(110) includes multiple rectifiers and multiple capacitors. The multiple rectifiers separate RF signals. The rectifiers rectify the separated RF signals. The multiple capacitors generate power voltage used as operating voltage of RFID. A first antenna(11) performs NF communication. A second antenna(12) performs FF communication.
