A method for tuning the antenna of a portable terminal including the steps of applying electromagnetic interference (EMI) paint to the inner surface of a case of the terminal; positioning a PCB having a ground inside the terminal; positioning an internal antenna above the upper end of the printed circuit board (PCB) while being spaced at a predetermined height; applying EMI paint to the inner surface of the case in a predetermined pattern to provide a first region having a ground; and applying EMI paint while changing the application pattern to provide a second region extending from the first region and having a ground, the shape of which is varied to change the frequency tuning of the antenna.
