摘要

An antenna device for a mobile terminal is provided to stabilize a characteristic of the device by installing matching circuits on both ends of a connection line connecting an antenna element with an RF board. An antenna device includes an RF(Radio Frequency) board(101) provided on a mobile terminal, an antenna element(102) connected to the RF board, a connection line(103) connecting the RF board with the antenna element, and matching circuits(111,121) provided on both ends of the connection line. The connection line is a coaxial cable. An antenna base is mounted in the terminal to support the antenna element, and a printed circuit board is mounted on the antenna base.
