Abstract: A multi-beam telecommunications antenna system with a focusing device including a two-dimensional radiator array generating a plurality of beams simultaneously by setting amplitude-time parameters of the signals for each radiator. The antenna includes: a focusing system having an amplifying lens; a radiating device, for irradiating the amplifying lens and having a two-dimensional radiator array, is disposed at a distance from the amplifying lens and covers a projection area of beams at this distance; and a beam forming system. At least one sub-array of the radiators provides a beam in a set direction. For each beam, the beam forming system provides, for each radiator in the corresponding sub-array, amplitude-time parameters of the signal being transmitted to form a non-planar wavefront, which is equidistant across the amplifying lens to a planar wavefront of the beam. The radiating surface of the radiator array is outside a region of self-intersection of the non-planar wavefronts.

Abstract: A multiple-feed antenna system includes a primary reflector that directs signals along a primary RF signal path and a movable subreflector assembly. When the subreflector assembly is in a first position, a first subreflector element of the subreflector assembly redirects signals traveling along the primary RF signal path to a first RF signal path and a second subreflector element of the subreflector assembly does not intersect the primary RF signal path. When the subreflector assembly is in a second position, the second subreflector element redirects signals traveling along the primary RF signal path to a second RF signal path and the first subreflector element does not intersect the primary RF signal path. The antenna system includes a first feed of the antenna system intersects the first RF signal path, a second feed that intersects the second RF signal path, and an actuator that moves the subreflector assembly.

Abstract: A method for achieving multiple beam radiation vertical orthogonal field coverage by means of multiple feed-in dish antenna, comprising using a total metallic disc and plural feed-in antenna components, wherein it is possible to generate multiple sets of radiation beams by applying multiple sets of feed-in antenna components, and the coverage ranges created by different radiation beams may uniformly distribute there between so as to generate multiple communication service coverage areas. Moreover, since the field formed by the reflection of the total metallic disc is characterized in vertical orthogonality, advantages such as effectively increased coverage, improved energy utilization and radiation beam switches or the like can be provided.
