Abstract
Systems, apparatuses and methods provides for technology that generates, with a phased array of elements of an antenna system, an array element radiation pattern over a scan angle range, where the phased array of elements is spaced at a predetermined wavelength spacing. The technology reflects, with a reflector of the antenna system, the array element radiation pattern emitted from the phased array of elements to Earth, and establishes, based on a shape of the reflector, a predetermined magnification as a function of scan angle range so as to increase the field-of-view of the antenna system. The technology adjusts, based on the shape of the reflector, the array element radiation pattern, by increasing magnification relative to the scan angle range, to have a gain that increases with increases in scan angle relative to a boresight of the antenna system, and reflects, with the reflector, radiation from Earth to the phased array of elements.
