Document Type and Number:
WIPO Patent Application WO/2002/071540
Kind Code:
A1
Abstract:
A reflector antenna comprising a Cassegrain reflector, and a mechanism for turning the reflector about the azimuth axis and the elevation axis so that it can be installed in a limited space while exhibiting a sufficient practicality and can perform scanning by turning about two axes perpendicular to each other. The reflector of substantially rectangular aperture is subjected to figuring such that the elevation angle thereof passes through the substantially central part of the height dimension of the reflector and the supplied electromagnetic wave is received substantially entirely and reflected and thereby the antenna height does not increase even when the reflector turns about the elevation axis.
