Patent number: 8773321Abstract: An antenna unit includes a housing, a substrate, and an antenna. The housing includes a bottom wall, first and second side walls extending upward from the corresponding side edges of the bottom wall, a rear wall extending upward from the rear edge of the bottom wall, and an upper wall extending from the upper edge of the first side wall toward the second side wall leaving a gap between an edge of the upper wall and the second side wall. The substrate is fixed to the upper wall, and a part of the substrate projects from the edge of the upper wall to a position that is closer to the second side wall than is the edge of the upper wall. The antenna is fixed to the part of the substrate projecting from the edge of the upper wall such that a radio-wave emitting aperture of the antenna faces forward.Type: GrantFiled: September 22, 2011Date of Patent: July 8, 2014Assignee: Fujitsu LimitedInventor: Michihiro Konishi

Patent number: 8559897Abstract: An information processing apparatus has radio communication function. A tilt detection unit detects a tilt of the information processing apparatus. An output changing unit changes an output of radio waves from an antenna for radio communication. Based on a detection result through the tilt detection unit, when a tilt ? of a predetermined external surface of a chassis of the information processing apparatus to a horizontal surface H is a predetermined angle or less, an output controller reduces an output of radio waves from the antenna to a predetermined value or less with respect to the output changing unit.Type: GrantFiled: April 16, 2012Date of Patent: October 15, 2013Assignee: Fujitsu LimitedInventors: Yasuhiko Isobe, Michihiro Konishi

Patent number: 8068059Abstract: An antenna device is mounted in a note PC and is used for communication between the note PC and the external of the note PC. The antenna device is provided with an antenna for wireless LAN for transmitting and receiving radio waves, and a cover. The cover is formed of a dielectric material for covering the antenna with a wall and a ceiling, and strengthens the directivity of radio wave communication on the wall side of the antenna device by a double layer structure of the ceiling that is thicker than the wall.Type: GrantFiled: August 28, 2008Date of Patent: November 29, 2011Assignee: Fujitsu LimitedInventor: Michihiro Konishi

Patent number: 7561106Abstract: The electronic equipment includes a housing accommodating an electronic circuit used in the operation of the device and a high-frequency circuit for wireless communication related to the operation of the device. A dielectric antenna is mounted on the rear surface of the housing near a lateral end thereof. Since the electronic circuit for operation and the high-frequency circuit for wireless communication are provided in the housing, it is not necessary to connect a personal computer and a mobile telephone by a cable thus making the device mobile. Further, since the dielectric antenna connected to the high-frequency circuit is mounted on the rear surface of the housing, the antenna characteristics can be improved and stabilized.Type: GrantFiled: June 7, 2004Date of Patent: July 14, 2009Assignee: Fujitsu LimitedInventor: Michihiro Konishi
