Abstract
A monopulse source for a focal feed antenna including at least two waveguides machined in a metal flange supporting a microwave transmission and reception circuit of the antenna, and a dielectric substrate on the metal flange. Also included is a microwave short-circuit having an opening with a smaller dimension than a dimension of a respective waveguide. The microwave short-circuit is mounted on the dielectric substrate such that an axis of the microwave short-circuit coincides with an axis of the respective waveguide. Further, a transition positioned on the dielectric substrate and within the opening of the microwave short-circuit is configured to couple the respective waveguide.
