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.

CADFEKO.

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.

Create a monopole antenna as a single line element with a local wire radius. Zoom to extents and hide the main axes
to view the full-length monopole in the 3D view.

Define a perfectly conducting (PEC) infinite ground plane. An infinite ground plane is an efficient method to model
a large ground plane compared to a discretised, finite sized ground plane.

Specify the frequency range of interest. For this example continuous frequency sampling is used where Feko determines automatically the frequency sampling for optimal interpolation.

Launch the Solver to calculate the results. No requests were added to this model since impedance and current information are calculated
automatically for all voltage and current sources in the model.

This example showed the construction, configuration and solution of an EMC coupling scenario. The model consists of
a monopole antenna and transmission line on an infinite PEC ground plane. Coupling of current into the transmission
line is viewed from 1 MHz to 30 MHz.

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.

Settings group, click the Frequency icon.

On the Solution frequency dialog, select
Continuous (interpolated) range from the drop-down list.

Specify the frequency range between 1 MHz and
30 MHz.

Enter the start frequency and end frequency.

Start frequency (Hz):
