Abstract

Disclosed herein is an antenna device for use with a portable wireless terminal. The antenna device includes a pair of chip antennas mounted on a main board of the terminal and adapted to transmit and receive high-frequency signals of different frequency bands, respectively, at least one pair of radiation plates electrically connected with the respective chip antennas, and a high-frequency signal line for electrically connecting the chip antennas with a circuit portion of the main board. With the antenna device of the portable wireless terminal configured according to the present invention, it is possible to mount the antenna device inside the terminal and to improve assembly productivity by allowing the antenna device to be simply mounted on a main board using a surface mounting device, as well as facilitate operation in different frequency bands.

Claims
