Easy setup of radially and axially corrugated horns
The component library in CHAMP allows easy design of axial corrugations, choke-ring waveguides and dual-depth corrugations, that may be excited at the throat by the fundamental mode or tracking modes. The simple design of axially corrugated horns can be further optimized by imposing a variable spline profile, or by changing the width and pitch dimensions of each individual corrugation. Optimized geometries can be exported as a CAD file (STEP).
Wizards for defining ring-focus VSAT geometries
By specifying only 4 parameters, a ring-focus (or axially displaced) antenna geometry of either the Cassegrain or Gregorian type can be defined. A combination of mode-matching of the interior feed waveguide field and a highly-efficient BoR MoM solver for the subreflector support and reflectors. A full analysis of a VSAT takes a few seconds per frequency, which makes it feasible to perform further optimization of the geometry using the optimization tool box.
Optimization of design goals
The user can easily formulate design goals in terms of familiar antenna parameters. Variables are included or excluded from the optimization through simple drag-and-drop, and upper and lower bounds may be specified on the variables. A selection of optimization algorithms is available, including minmax, least-squares, genetic and simplex.
Simple interface to GRASP and POS
CHAMP generates GRASP and POS compatible spherical wave expansions to enable full secondary pattern predictions of complex offset antenna systems using the designed feed as source.
