Built-in library of predefined components
In CHAMP 3D the user can build a complex 3D or rotationally symmetrical waveguide assembly or feed by selecting from a library of predefined components or load the assembly/component from a CAD file. Scattering parameters and radiation from feeds excited by arbitrary waveguide modes or any combination hereof can be calculated.
Easy design optimisation
The optimisation algorithms available for any product in TICRA Tools offer both global and local methods for thorough design developments. S-parameters and return loss are typically considered in CHAMP 3D, just as the feed pattern may be formed to meet a specific illumination pattern. Rotationally symmetric terminals with one or two reflectors can be made to meet patterns constraints, e.g. sidelobe roll-off.
Seamless integration of CHAMP 3D and GRASP in one interface
In combination with GRASP in TICRA Tools it is possible to directly optimise feed chains for reflectors based on the final performance, i.e. the far-field radiation pattern from the entire antenna system, as opposed to optimising, e.g. the isolated feed to meet requirements defined on the subsystem level.
