Array antenna synthesis including element and feed coupling
Precise radiation pattern control for an array antenna requires precise control of array element excitations. One application is that of low side lobe patterns. Classical synthesis methods for the desired pattern may not be realized in practice due to coupling effects. Coupling occurs in two forms: …

The optimal starting point for antenna array design
… numerous ""novel"" one-off solutions as well as synthesis methods exist, these often gloss over initial design decisions and problem-specific conditions, limiting their usefulness across different scenarios. Furthermore, arrays are almost always limited to similar antenna elements, and even when …

Synthesis of dual offset Gregorian reflector antennas with very low cross polarization under practical constraints for mass production
… of axisymmetric and offset reflector antennas. Single and dual reflector configurations are considered. Cross polarization (XPOL) and beam squint are examined in detail. Although many of the phenomena are known, they are interpreted and explained in new ways and presented in a single …
