Mobile device having RFID system

Abstract

A mobile communication terminal has a radio frequency identification (RFID) system to read information from RFID tags at predetermined distances. An RFID transmission antenna to transmit or receive a wireless signal for mobile communication to/from a base station, or transmit wireless signal to the RFID tag, and an RFID reception antenna to receive RFID wireless signal transmitted from the RFID tag. Accordingly, ingress of the RFID transmission carrier leakage to the RFID reception circuit can be prevented. Additionally, a small size antenna such as a chip ceramic antenna is used exclusively for RFID reception, and the RFID reception antenna is also used as a mobile communication antenna. As a result, the mobile communication terminal can be compact-sized, the size of transmission signal can be increased, and dynamic range increases without having to increase the sensitivity of the RFID tag, to extend the communication distance.
