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.

A monopulse source for a focal feed antenna, comprising:
- at least two waveguides machined in a metal flange supporting a microwave transmission and reception circuit of the antenna;
- a dielectric substrate on the metal flange;
- a respective microwave short-circuit having an opening with a smaller cross-sectional dimension than a cross-sectional dimension of a corresponding one of said at least two waveguides, said respective microwave short-circuit being mounted on the dielectric substrate such that an axis of the respective microwave short-circuit coincides with an axis of the corresponding one of said at least two waveguides;
- and
- a respective transition positioned on the dielectric substrate and within the corresponding opening of the respective microwave short-circuit, and configured to excite the respective waveguide.
