An antenna reflector () comprising a centrally located hub (), inner ribs () rotatably secured at a proximal end to the hub, outer ribs () extendible from the inner ribs, and a guideline truss structure () configured to support a flexible antenna reflector surface (). The inner ribs are rotatable from a stowed position in which they are generally aligned with a central axis of the hub, to a rotated position in which they extend in a radial direction relative to the central axis. The guideline truss structure is secured to each outer rib using standoff cords attached at intermediate locations along a length of the outer rib between opposing ends () thereof. The outer ribs are configured to be linearly displaced respectively along an elongated length of the inner ribs from a proximal position adjacent to the hub, to an extended position distal from the hub.

Extendable rib reflector

A boom structure is deployable from a collapsed, stowable configuration to an elongated truss configuration. The boom structure contains a plurality of truss-forming multi-sided bays. A bay contains a pair of battens joined together at corner regions by foldable longerons. A side of a bay has a plurality of diagonal cord members crossing one another and connected to diagonally opposed corner regions of the side. When the longerons are in their folded positions, the battens are nested together against one another in a stacked arrangement and the diagonal cord members flex into a compact stowed configuration between adjacent battens. The stowed battens are compressed to each other at their corners to form a stowed structure capable of reacting loads.
