Intuitive and easy-to-use even for non-expert users

Specialized and focused solely on the antenna design, CENOS software has only the relevant features, therefore reducing the learning curve. Less tinkering over the software means more time to work on the product development.

  • Choose from a variety of ready-made antenna design templates.

  • Create your own design or import your CAD or STL files.

  • Customizable object library.

  • Process with automatic, adaptive/adjustable meshing.

  • Extensive frequency-accurate material database of common dielectric materials suited for antennas

  • Automatic geometry parameterization adjusts the parameters based on the goals you have set.

Integrates with your favorite CAD software

CENOS integrates FreeCAD geometry editor to handle geometry of any complexity, provides built-in utilities for the handy design of microstrip antennas and arrays, feed networks, wire antennas (including import of NEC files), and arbitrary 3D structures.

It also integrates with Autodesk Inventor, Solidworks, Fusion360, and KiCAD.

Faster simulation.
Faster development.

Reducing computer modeling time is our top priority. Our approach is to trim any excess functionality leaving only necessary for Antenna Design, and automate mundane tasks.

  • Parallel calculation (multi-CPU)

  • Workbench for parameters optimization

  • Automatic meshing

  • Fast frequency sweep
