<p>A sliding type portable wireless device comprises a first housing; a second housing that slides with respect to the first housing, and that is positioned at either a first relative position or a second relative position that is different from the first relative position; an antenna element built-in within the first housing; and a plurality of parasitic elements including first and second parasitic elements that are formed within the second housing, and that capacitively couple with the antenna element. The first parasitic element comes to face the antenna element at the first relative position. The second parasitic element comes to face the antenna element at the second relative position.</p> |
