Title:
LENS ANTENNA DEVICE FOR MOBILE COMMINCATIONS
Document Type and Number:
WIPO Patent Application WO2004073102
Kind Code:
A3
Abstract:
A lens antenna device for mobile communications has an antenna having a spherical Luneberg lens or a hemispherical Luneberg lens with a reflector and further having a primary emitter and a support arm for the emitter, a cover for covering the antenna, a level-adjusting mechanism with an antenna-leveling mechanism, means for confirming antenna's own position, and an antenna orientation-adjusting mechanism including orientation-confirming means. The lens antenna device is mounted on a mobile body and performs highly sensitive reception of radio waves from a stationary satellite etc. In the lens antenna device during the movement of the mobile body, an initial position of the antenna is maintained by leveling through the antenna-leveling mechanism and by automatic orientation correction based on own-position information and orientation information.
