Supply system and reflector integrated antenna for covering geographical area of geostationary orbit, has main reflector with reflective surface that is conformed of three-dimensional manner to reflect beam delivered by each source

摘要

The antenna has a control unit (50) controlling amplitude and/or phase of elementary sources (40) e.g. printed elements. A main reflector (30) has a reflective surface that is conformed of three-dimensional manner to reflect beam delivered by each source by spreading its energy so that the surface covers a selected geographical area, where concentric circular areas are intersected with the geographical area to define sub-areas. The sub-areas are characterized by gain constraint, so that one sub-area is farthest from center of the geographical area that is covered by radiation from the sources.
