Abstract
An antenna reflector (100, 700) comprising a centrally located hub (120), inner ribs (108) rotatably secured at a proximal end to the hub, outer ribs (110) extendible from the inner ribs, and a guideline truss structure (132, 160) configured to support a flexible antenna reflector surface (122). 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 (116, 118) 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.
