A space antenna may include an extendible boom movable between stored and deployed positions. An extendible hoop may surround the extendible boom and is movable between the stored and deployed positions. A front cord arrangement may be coupled to the extendible hoop and defines a curved shape in the deployed position, and a reflective layer may be carried thereby. A rear cord arrangement may be behind the front cord arrangement and coupled between the extendible hoop and the extendible boom. The rear cord arrangement may include a rear plurality of interconnected cords defining rear polygons. Tie cords may extend between the front cord arrangement and the rear cord arrangement. A top cord arrangement may be above the reflective layer and coupled between the hoop and the extendible boom.

Space antenna having extendible hoop and interconnected cords defining polygons and related methods

A method for deploying a trough structure. The methods comprise: causing a first telescoping segment to move in a first direction away from a proximal end of a telescoping boom; and transiting a flexible element from an untensioned state to a tensioned state as the first telescoping segment is moved in the first direction. The flexible element is coupled to a distal end of the first telescoping segment by a first bulkhead and is coupled to a distal end of a second telescoping segment by a second bulkhead. The first telescoping segment is coupled to the second telescoping segment of the boom when the first telescoping segment reaches an extended position. The flexible element has a parabolic trough shape when in the tensioned state.
