• 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
  • Fast recalculation of waveguide assemblies by use of the Generalized Scattering Matrix (GSM) approach for decomposing the assembly into smaller components
  • The most appropriate solver (analytical expressions, mode matching, higher-order BoR-MoM, or higher-order 3D MoM) is selected for each component
  • Dedicated wizard and 2D editor for easy geometry setup of corrugated horns, smooth-wall horns as well as rotationally symmetric single, dual, and ring focus reflectors
  • Direct optimisation with goals on scattering parameters as well as primary and secondary radiation patterns


  • Seamless integration with other products in TICRA Tools
  • Fast analysis and optimisation
  • Feeds, waveguides, and reflectors can be analysed and optimised as a single model

Library of predefined components or build from scratch

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 construct the waveguide or feed from scratch using simple Boolean operations. It is also possible to 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.

Simple setup of rotationally symmetric horns and VSATs

The dedicated wizard and 2D editor, known from CHAMP, can be used for easy setup of axially or radially corrugated horns, smooth-wall horns as well as rotationally symmetric reflectors and VSATs.

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.
