CHAMP 3D lets users design complex waveguide feeds and assemblies via a component library or CAD imports. It calculates scattering parameters and radiation for arbitrary mode excitations. Wizard tools simplify horn and reflector setup. Integrated optimization helps achieve targeted patterns, minimize losses, and accelerate antenna development.
Calculate scattering parameters for 3D and rotationally symmetric passive metallic and dielectric waveguide components.
Calculate reflection coefficients, scattering parameters, and radiation patterns for rotationally symmetric and arbitrarily shaped feeds.
The most appropriate solver (analytical expressions, mode matching, higher-order BoR-MoM, or higher-order 3D MoM) is selected for each component.
By modeling and optimizing a matched-feed horn for an offset reflector, cross-polarization is reduced by over 12 dB. Using CHAMP 3D and GRASP, horn and feed elements are tuned to boost antenna performance in demanding telecom applications.
