MULTISEGMENT ARRAY-FED RING-FOCUS REFLECTOR ANTENNA FOR WIDE-ANGLE SCANNING
Last updated:
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.
