The example is intended for users with no or little experience with CADFEKO. It makes use of a completed rectangular horn model to familiarise yourself with model creation in CADFEKO and viewing the simulated results in POSTFEKO.
The example is intended for users with no or little experience with CADFEKO. This example is not an example intended for simulation, but rather to familiarise yourself with model creation in
CADFEKO.
Add a wire feed to the model. As this example is only for demonstration purposes, this example does not cover the
adding of a port or source to the wire feed.
Create an aperture (hole) in a face or region by using the subtract tool. Create the geometry to be removed and subtract
it from the target part. The target is the part that is reduced by cutting away a section of the part.
The example considers the reflection coefficient and impedance of a microstrip patch antenna on a substrate modelled
on an infinite substrate and then on a finite substrate.
Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses
involving 3D objects of arbitrary shapes.
EDITFEKO is used to construct advanced models (both the geometry and solution requirements) using a high-level scripting language
which includes loops and conditional statements.
One of the key features in Feko is that it includes a broad set of unique and hybridised solution methods. Effective use of Feko features requires an understanding of the available methods.
Feko offers state-of-the-art optimisation engines based on generic algorithm (GA) and other methods, which can be used
to automatically optimise the design and determine the optimum solution.
Feko writes all the results to an ASCII output file .out as well as a binary output file .bof for usage by POSTFEKO. Use the .out file to obtain additional information about the solution.
CADFEKO and POSTFEKO have a powerful, fast, lightweight scripting language integrated into the application allowing you to create
models, get hold of simulation results and model configuration information as well as manipulation of data and automate
repetitive tasks.

Align the back face centre of the horn on the front upper edge of the
cuboid.
Select Subtract1 in the model tree.
On the Transform tab, in the
Transform group, click the Align icon.
Place the Source workplane by holding down Ctrl+Shift to snap to the face centre at the back
of the horn.
The destination workplane is to be set on the top and nearest edge of the
cuboid at an angle of 45° to the cuboid.
Rotate the horn by using a sequence of rotations around the U,V and/or N axis, depending on the original placement and direction of the
source workplane.
Tip: To rotate by 45°, enter
45 in the field of the relevant axis and press
one or a combination of the , , or buttons.
Click OK to apply the transform and to close the
dialog.
Union the cuboid and horn to ensure mesh connectivity.
Select both Cuboid1 and Subtract1
in the model tree.
On the Construct tab, in the Modify
group, click the Union icon.
