Abstract
Optimizations are provided in the design and fabrication of a parabolic antenna reflector. In particular, a parabolic antenna reflector comprises an inner reflective face being formed in a parabolic shape and a first outer circumferential portion. The parabolic antenna also includes an outer face being formed in a different parabolic shape and a second circumferential portion. 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. This inner body includes a monopulse comparator waveguide. As a result, the monopulse comparator waveguide is embedded between the inner reflective face and the outer face. In some instances, this waveguide includes one or more bends. Additionally, in some instances, the parabolic antenna reflector is fabricated using additive manufacturing techniques such that the parabolic antenna reflector is a single printed unit.
