摘要： An ultra wideband antenna is provided that filters a predetermined frequency signal. The ultra wideband antenna includes a power feeding part that receives a supply of an external electromagnetic energy; a radiator excited by the electromagnetic energy fed through the power feeding part and radiating an electromagnetic wave; and a stub, provided on the radiator in a direction parallel to a direction of an electric field formed by the electromagnetic wave, that intercepts transmission/reception of a predetermined frequency band signal. The length of the stub may be ¼ of a wavelength of the intermediate frequency of the predetermined frequency band to be removed to filter the corresponding frequency band signal. The ultra wideband antenna simplifies the construction of an ultra wideband receiving system with the power loss and noise characteristics of the system improved.

摘要： 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.
