    • 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.
    • 移动通信终端具有用于从预定距离的RFID标签读取信息的射频识别(RFID)系统。 用于发送或接收用于向基站进行移动通信的无线信号或者向RFID标签发送无线信号的RFID发送天线以及用于接收从RFID标签发送的RFID无线信号的RFID接收天线。 因此,可以防止RFID传输载体泄漏到RFID接收电路的入口。 此外,诸如芯片陶瓷天线的小尺寸天线专门用于RFID接收,并且RFID接收天线也用作移动通信天线。 结果,移动通信终端可以小型化,可以增加传输信号的大小,并且动态范围增加而不必增加RFID标签的灵敏度,从而延长通信距离。
