The utility model relates to a miniaturized ultra-wideband reflector antenna, and belongs to the field of electronic science and technology subjects. The ultra-wideband feed source comprises a paraboloid, an ultra-wideband feed source arm and an ultra-wideband balun. The ultra-wideband feed arm is a feed source of the paraboloid, the initial end of the feed arm is located at the focus of the paraboloid, the tail end of the feed arm is located at the edge of the paraboloid, the ultra-wideband balun coincides with the axis of the paraboloid and penetrates through the paraboloid, the initial end of the ultra-wideband balun is located at the back of the paraboloid, and the tail end of the ultra-wideband balun is located at the focus of the paraboloid and connected with The feed source arm with the asymptotically conical profile has the ultra-wideband characteristic similar to that of a biconical antenna, and the resistor is loaded at the tail end, so that the electrical size of the antenna is greatly reduced, and
