Abstract: A multisegment array-fed reflector antenna includes a feed array consisting of a number of subarrays and a multisegment reflector to reflect multiple beams of the feed array into a number of elevation angles. A support structure couples the multisegment reflector to the feed array. The multisegment reflector includes two or more ring-focus parabolic segments, and each ring-focus parabolic segment is a parabolic surface extending along a circle around the support structure.

Abstract: A Reconfigurable, Flexible Multi-User (RFMU) electronically steered antenna (ESA) includes a top panel and a number of side panels that enable many contacts simultaneously with varying gain requirements from a single, in situ, installation. The top panel includes multiple subarrays and can communicate with flyover satellites, and the side panels can communicate with satellites flying past a side of the ESA. The top panel and the side panels can achieve a beam steering that covers a full or partial, variable gain, hemispheric field-of-view (FoV). The RFMU ESA terminal top and side panels are scalable using flexible modular building blocks. This enables increased contacts, increased gain or a combination thereof sized to meet desired performance.
