Cassegrain antenna which can be pivoted

摘要

The Cassegrain antenna which can be pivoted about two axes (8, 9) has a supply system which is composed of a short excitation horn radiator (5) having a beam-focusing dielectric lens (16) in its aperture region and having a beam waveguide system which consists of two or more flat deflection mirrors (6, 7). The antenna construction in accordance with the invention can be used especially as a ground station antenna for satellite radio. <IMAGE>
