Abstract
A mobile terminal is provided having an radio frequency identification (RFID) function and includes an antenna which transmits and receives a radio signal; a radio frequency identification matching circuit which changes an operating band of the antenna to a frequency band where an RFID radio signal is input and output; a communication module which processes a mobile communication radio signal transmitted and received via the antenna; and a switch which connects the antenna to either the communication module or the RFID matching circuit according to whether an RFID function is used or not. Accordingly, the compactness of the mobile terminal can be realized, and the RFID communication performance can be enhanced.
