This software is a part of the Open-RFlab project and relies on the octave-openems-hll library, if you are interrested in contributing or involved in an other somewhat -> openems
converter please take a look.
- Better example : A low pass filter designed, produced and measured by F4HDG. Thanks to him!
-
Generated scripts outputs :
- Touchstone file (
.sxp
) - S parameters (Smith chart and orthogonal)
- Feed point impedance
- Feed point VSWR
- Phase response (wrapped and unwrapped)
- Phase delay and group delay
- Azimuth & elevation far field radiation pattern (polar and orthogonal, normalized and in dBi)
- 3D far field radiation pattern for multiple frequencies (animated
.gif
) - Electric & magnetic fields, current and current density in time domain (visible with Paraview)
- Touchstone file (

Here is a tutorial.
- Qucs or Qucs-S is needed (even if you want to convert QucsStudio files), be sure it is installed and accessible from your
PATH
variable. - OpenEMS scripts dependencies :
- OpenEMS (
octave-openems
package available on Debian based distros,octave-openEMS
on openSUSE) - ImageMagick (packages available on most distros)
- OpenEMS (
-
For Debian based distributions, a repository is available here.
-
For RPM based distributions and Windows, you can download packages here.
- Nix way (non-NixOS) :
nix profile install --impure 'github:thomaslepoix/Qucs-RFlayout#qucsrflayoutNixGL'
-
Debian way : Take a look on the debian branch.
-
Classic way :
The build-time dependencies are the following on Debian, check equivalents on your own (reports are welcome) for non Debian-based distros :
qt6-base-dev
, libqt6opengl6-dev
, texlive-xetex
, fonts-lato
Qucs-RFlayout $
cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release
cmake --build build
sudo cmake --build build --target install
qucsrflayout -i qucs-schematic.sch -o output-directory -f .output-format
- Microstrip only for now, coplanar waveguide ASAP.
- Any other component cannot be converted into a geometric shape of metal by this tool.
- Use one wire to connect only two component ports, use appropriate components to make tees or crosses.
- QucsStudio schematics are supported (2.x versions only) but it is closed source and there are some incompatibilities, so please prefer using Qucs. If you really need to work with QucsStudio 3.x, take a look at this converter.
