<p>A portable wireless device including a first housing (101) and a second housing (102) foldably coupled via a hinge (104), and a third housing (103) including an approximately rectangular display part (106) coupled with the second housing (102) by a rotary mechanism (105) rotatable in a plane parallel to the surface of the second housing. An antenna (107) is provided at a hinge side end of the first housing (101), and a passive element (108) is provided at an end of the third housing (103). When a user views video data on a landscape oriented screen, the antenna (107) and the passive element (108) are electromagnetically coupled with each other by rotating the third housing (103) by 90 degrees, to improve antenna characteristics of the antenna (107). Thus, a more efficient antenna can be provided when the user views the video data on the landscape oriented screen in the portable wireless device capable of receiving digital terrestrial TV broadcast or other video data.</p> |
