    摘要: An antenna apparatus for a portable terminal having a main board is provided. The antenna apparatus includes a main antenna that electrically connects to a feed line of the main board. A metal frame is constructed as part of a case frame forming an exterior of the portable terminal. The metal frame is divided into first and second parts that are separated. The first part electrically connects to the main antenna or to the main board feed line, and is designed to radiate. The second part electrically connects to a ground surface of the main board. The metal frame enhances overall antenna performance rather than causing degradation through interference.

    摘要: An encryption/decryption device and a method thereof use an RC4 algorithm to reduce a waiting time for encryption/decryption thereby avoiding data process delay. The encryption/decryption device includes a management unit, an encryption/decryption unit, and a first interface. The management unit includes a WEP seed key generator for generating a WEP seed key based on a transmitter address of first data and a cipher suite value representing a cipher protocol type for the transmitter address, an RC4 key scheduler for generating S-Box data using the WEP seed key, and an S-Box data memory storing the S-Box data generated from the RC4 key scheduler for the transmitter addresses. The encryption/decryption unit has a core for performing the RC4 algorithm corresponding to the cipher suite, encrypting/decrypting the first data using the S-Box data transmitted from the management unit, and transmitting a signal for generating the S-Box data of second data to the management unit. The first interface transmits a control signal and a data signal between the management unit and the encryption/decryption unit.

    摘要: An apparatus for multiple antennas having a low coupling coefficient in a wide frequency bandwidth in a wireless communication system is provided. To obtain the low coupling coefficient in the wide frequency bandwidth by minimizing interference between antennas which are close to each other, without an additional device, in the wireless communication system, the apparatus includes a transceiver and a line for decreasing a coupling coefficient. The transmitter includes a first antenna and a second antenna for transmitting and receiving signals over a radio channel and the line is indirectly connected the first antenna and the second antenna using a physically disconnected line.
