ABSTRACT:
The present invention relates to a device and method for improving a radiation pattern of a built-in antenna in a folder-typed mobile wireless terminal that has a main body having the RF board installed with a built-in antenna, a sub-body to be opened and closed at an angle from the main body, and a hinge module configured to open and close the sub-body. The device includes a conductive ground means installed in the sub-body at a portion adjacent to the built-in antenna, for minimizing a radiation pattern difference of the built-in antenna between the opening and closing of the sub-body, thereby increasing reliability of the terminal.
