Patent number: 6061579Abstract: A hand-held satellite mobile phone terminal contains an antenna deployment element with a small antenna attached to the tip area of the antenna deployment element The antenna deployment element is usually folded and stored on the rear side surface of the body of the hand-held satellite mobile phone terminal, and is deployed to become vertical to the rear side surface of the hand-held satellite mobile phone terminal body when it is used. The antenna deployment element is attached to the body of the hand-held satellite mobile phone terminal through a rotational axis so that the small antenna attached to the antenna deployment element can be rotated after deployment in order for its plane to become parallel with the ground surface. Also, the hand-held satellite mobile phone terminal is usable both in a satellite communication system and in a terrestrial cellular communication system.Type: GrantFiled: June 24, 1997Date of Patent: May 9, 2000Assignee: Advanced Space Communications Research LaboratoryInventors: Hiroyuki Arai, Hitoshi Hoshino, Yuichi Otsu, Takashi Miyoshi
