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.
