(by J. Uher, J. Bornemann, and U. Rosenberg) is a comprehensive technical resource widely recognized as a "complete source" for advanced CAD procedures in antenna feed networks. Core Focus and Technical Depth

Used in monopulse tracking radars and phased array feeds, hybrids split signals into equal or quadrature-phased outputs. The and branch-line coupler are common designs in planar waveguide form.

How do these components fit together? Let’s look at two typical configurations:

The "feed system" is the conduit that transfers RF energy from the transmitter (source) to the antenna, or from the antenna to the receiver. It is a precision assembly of various components, each performing a specific electromagnetic function.

The primary paths for signal travel, designed for low attenuation .
