    摘要： A small broadband monopole antenna having a perpendicular ground plane with an electromagnetically coupled feed is provided. The small broadband monopole antenna may be realized as a small antenna having a size of 0.085λ0×0.085λ0×0.085λ0 by positioning a folded strip line under a shorted square disc. A resonance of the shorted square disc may be coupled to a resonance of the square folded strip line so as to form a wide bandwidth of about 36.6% of a central frequency of 2.313 GHz based on a VSWR≦2. Also, rectangular slits may be inserted into the perpendicular ground plane to improve a distortion of a radiation pattern that forms on the perpendicular ground plane so as to reduce a backward radiation by 3 dBi or more. The small broadband monopole antenna exhibits a forward radiation pattern similar to that of a general monopole antenna and has a gain of about 2.6 dBi within a bandwidth.

    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.

    摘要： A slot antenna is provided. The slot antenna includes a feeding unit of a strip line shape which is disposed on a first surface of a substrate, a ground which is disposed on a second surface of the substrate, and an antenna element which is formed by connecting two sub slots formed on the second surface of the substrate, wherein each of the sub slots is arranged at an edge of the ground in an internal direction of the ground. Accordingly, the size of the antenna is reduced, and more area is provided for arranging components of a terminal.
