Abstract (en)
[origin: EP0252247A1] The collapsible antenna reflector (1) with a concave surface for very high contour precision, consists of rigid segments (7) of identical shape with a central panel (2) to which the segments (7) are connected by means of two single-axle hinges (5). The central panel (2) has a circular-saw shaped contour corresponding to the number and the connection width of the segments (7), on the sections (4) of which contour there are arranged the hinges (5), with axles (6) running parallel thereto, and to which hinges (5) the segments (7) are connected such that they can pivot. <IMAGE>
