Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/014951
Kind Code:
A1
Abstract:
Disclosed is an antenna device provided with a reflecting mirror which reflects radiowaves from a plurality of satellites in geostationary orbit, and a plurality of radiators each of which is located at a position where the radiowaves from each of the satellites and reflected by the reflecting mirror can be received so as to receive the radiowave from each satellite. A mirror surface of the reflecting mirror is defined by a merged paraboloidal surface formed by arranging and merging a plurality of individual paraboloidal surfaces to be in contact with one merging point wherein each paraboloidal surface is capable of collecting the radiowaves from each of the plurality of satellites to a focus position corresponding to the position that each radiator is set. The reflecting mirror has the same shape as the merged paraboloidal surface cut along a cutting plane which can be seen as one straight line intersecting the central axis of the merged paraboloidal surface, when the merged paraboloidal surface is viewed from the side face direction perpendicular to the central axis of the merged paraboloidal surface passing through the merging point.
