1. A parabolic antenna reflector comprising:an inner reflective face being formed in a parabolic shape, the inner reflective face including a first outer circumferential portion; and
an outer face being formed in a different parabolic shape, the outer face including a second outer circumferential portion,
wherein the first outer circumferential portion is coupled to the second outer circumferential portion to form an inner body between the inner reflective face and the outer face, and
wherein the inner body comprises a first monopulse comparator waveguide such that the first monopulse comparator waveguide is embedded inside the inner body between the inner reflective face and the outer face.
