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.

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.

Calculate the input impedance of a microstrip patch antenna close to 2.8 GHz. The substrate is considered as an infinite
planar multilayer substrate as it is more resource efficient. The substrate is then modelled as a finite substrate
to make it a more realistic model.

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.

Calculate the input impedance of a microstrip patch antenna on a finite substrate. Modify the previous model by removing
the infinite planar multilayer substrate and creating a finite substrate.

This example showed the construction, configuration and solution of a microstrip patch antenna. The model was constructed
from an infinite substrate and ground plane in the former case, and a finite substrate in the latter case.

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.
