Abstract

Disclosed is a method of manufacturing a reflector dish for a compact antenna test range, CATR, and a reflector dish being obtainable by the method. The method comprises providing a first workpiece having an axis of symmetry, and an unprocessed peripheral edge with respect to the axis of symmetry fitting within a maximum milling area of a milling device. The method further comprises milling a concave parabolic frontal surface into the first workpiece in accordance with the axis of symmetry. The method further comprises milling a peripheral surface into the first workpiece with respect to the axis of symmetry. The method further comprises providing four second workpieces. The method further comprises milling a frontal surface into the respective second workpiece. The method further comprises milling a peripheral surface into the respective second workpiece. The method further comprises merging the first workpiece and the second workpieces to form a rectangular main body, wherein the peripheral surfaces abut seamlessly with one another and the frontal surfaces merge seamlessly into one another.
