Antenna phased arrays of these technical solutions are in the form of flat sections, the sections of the antenna phased arrays can be supported from the back side of the antenna power frame, made in the form of shaped structures, see, for example, the device space of RADARSAT-1 (specified source, str). The antenna is the large dimensions of the module of remote sensing "Nature" (see str specified source) made in the form of clippings paraboloid of revolution and composed of front and rear covers and the frame in the form of a rod system.
