Title:
A device for an antenna system
Document Type and Number:
Japanese Patent JP5954988
Kind Code:
B2
Abstract:
An apparatus for an antenna system comprising means for cutting the energy in the electric field received by an antenna into a plurality of portions and redirecting said plurality of portions for detection by a plurality of detectors. The means for cutting the energy in the electric field may comprise a plurality of blades for cutting the energy into successively smaller and smaller portions. The plurality of detectors can be positioned outside the focal region of the antenna system. If the dimensions of the detectors are required to be relatively large, the system can then detect more closely packed beams than if the detectors had been positioned in the focal region. The apparatus may further comprise focusing means for focusing the cut energy onto another blade or a detector. There is also provided an antenna system comprising a plurality of feed horns for producing a plurality of beams; and a plurality of elements for redirecting said beams towards a focal region of the antenna system so as to form a group of closely packed beams for transmission by the antenna system.
