MOBILE DEVICE HAVING A RFID SYSTEM

摘要

A mobile terminal having an RFID(Radio Frequency IDentification) system is provided to prevent an RFID Tx carrier leakage signal from being inputted to an RFID receiving circuit by separating an RFID transmitting antenna from an RFID receiving antenna and to achieve the miniaturization of the mobile terminal by using the RFID transmitting antenna as an antenna for mobile communication in common. A mobile terminal having an RFID system, which reads information from an RFID tag arranged within a certain distance, comprises an RFID transmitting antenna(110) and an RFID receiving antenna(120). The RFID transmitting antenna(110) transmits a radio signal to the RFID tag. The RFID receiving antenna(120), installed separately from the RFID transmitting antenna(110), receives an RFID radio signal from the RFID tag. The RFID transmitting antenna(110) is manufactured in the form of a whip antenna, a PIFA(Planar Inverted F Antenna) or a patch antenna. The RFID transmitting antenna(110) is a main antenna which is used as an mobile communication antenna for transmitting/receiving mobile communication radio signals.
