摘要： The described features generally relate to adjusting a native antenna pattern of a satellite to adapt communications via the satellite. For example, a communications satellite may include an antenna having a feed array assembly, a reflector, and a linear actuator coupled between the feed array assembly and the reflector. The feed array assembly may have a plurality of feeds for communicating signals associated with a communications service, and the reflector may be configured to reflect the signals transmitted between the feed array assembly and one or more target devices. The linear actuator may have an adjustable length, or otherwise provide an adjustable position between the feed array assembly and the reflector. By adjusting the position of the feed array assembly relative to the reflector, the communications satellite may provide a communications service according to a plurality of native antenna patterns.

摘要： An antenna system comprises an antenna feed support and a driver. The antenna feed support is configured to mount a circularly polarized antenna feed to an antenna dish to extend outward along a longitudinal axis of the circularly polarized antenna feed with respect to a reflective surface of the antenna dish. The driver is configured to rotate the circularly polarized antenna feed to adjust alignment between the circularly polarized antenna feed and a remote antenna. The driver can rotate the circularly polarized antenna feed mechanically, electrically or both to adjust alignment between the circularly polarized antenna feed and a remote antenna to reduce cross-pol discrimination at the circularly polarized antenna feed.

摘要： A steerable antenna architecture, or configuration, for optimal steering of transmitting and/or receiving beam over wide scan angles, is capable of steering the beam on a full hemisphere (2π steradians), with no singularity or key-hole within a coverage area and with only one RF rotary joint. The architecture includes a dual-reflector assembly defining an antenna focal point located close to a main reflector surface and a signal feed chain having a signal source located adjacent to the antenna focal point and defining a feed axis substantially pointing towards a sub-reflector intersection point. A first actuator rotates the feed chain and the dual-reflector assembly about a first rotation axis generally perpendicular to the feed axis and not intersecting with the coverage area. A second actuator rotates one of the main reflector and the dual-reflector assembly about a second rotation axis aligned with the feed axis.
