  • Patent number: 11721909
    Abstract: An antenna structure may include a solid antenna structure and a mesh antenna structure. The mesh antenna structure may be coupled to an outer edge of the solid antenna structure through two or more ribs. The two or more ribs may be configured to extend away from the solid antenna structure to expand the mesh antenna structure and increase a surface area of the antenna structure.
    Type: Grant

  • Patent number: 10553942
    Abstract: Systems and methods are disclosed herein for a reconfigurable faceted reflector for producing a plurality of antenna patterns. The reconfigurable reflector includes a backing structure, a plurality of adjusting mechanisms mounted to the backing structure, and a plurality of reflector facets. Each of the plurality of reflector facets is coupled to a respective one of the plurality of adjusting mechanisms for adjusting the position of the reflector facet with which it is coupled. The reflector facets are arranged to produce a first antenna pattern of the plurality of antenna patterns. By adjusting the plurality of adjusting mechanisms, the position of each of the reflector facets coupled to the respective one of the plurality of adjusting mechanisms is adjusted so that the reflector facets are arranged to produce a second antenna pattern of the plurality of antenna patterns.

  • Publication number: 20060250316
    Abstract: An antenna system for producing selectively reconfigurable antenna beam coverage patterns suitable for use in on an earth orbiting spacecraft is described. The system comprises a main reflector and a feed element with a subreflector module on which are disposed one or more subreflectors. The subreflector module is selectably positionable such that any one of the subreflectors may be disposed such that it is illuminated by the feed element and illuminates the main reflector. Each of the subreflectors has a shaped surface corresponding to a desired antenna beam coverage beam pattern. By appropriate selection from among the plurality of subreflectors, any one of a plurality of antenna beam coverage patterns can by provided with a single feed element and single main reflector.
