Hosted, compact, large-aperture, multi-reflector antenna system deployable with high-dissipation feed
Last updated:
Abstract:
A hosted multi-reflector antenna system includes a primary reflector, a subreflector, an aperture, a feed structure and an anti-jam housing. The feed structure includes an electronically steered antenna (ESA). The subreflector directs a reflected beam between a primary reflector and an ESA, and the anti-jam housing encloses the subreflector and the ESA. The antenna system is thermo-elastically decoupled and thermally self-sufficient, accommodates thermal dissipation of the feed structure, and can maintain a precise antenna alignment.
