Patent number: 7787915Abstract: In a folding mobile radio device, a gain is lowered considerably in its close state under such a condition that an upper case is excited directly in its open state to aim at a wide band and a high gain is used as an antenna. A folding mobile radio device includes a first case, a second case, a jointing portion for connecting the first case and the second case to open/close, a conductor element arranged in the first case, and a feeding element arranged in the second case. Then, in an open state via the jointing portion, the conductor element and the feeding element come close to each other and are coupled magnetically at a time of feeding a power whereas, in a close state via the jointing portion, the conductor element and the feeding element are apart from each other rather than the open state and are not coupled magnetically at a time of feeding a power.Type: GrantFiled: July 12, 2005Date of Patent: August 31, 2010Assignee: Panasonic CorporationInventors: Hiroyuki Uejima, Yutaka Isoda, Nobuharu Mashima, Masayoshi Hirai, Nobuhiro Iwai, Yutaka Saitoh, Kenichi Maeda
