The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
EMC Coupling
The example considers the coupling between a typical monopole antenna and a loaded transmission line above a ground plane.
Launching the Solver
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.

Get Started
The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
- Creating a Rectangular Horn
  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.
- Creating CADFEKO Models
  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.
- GPS Patch Antenna
  The example considers a left-handed circular polarised GPS patch antenna on a finite substrate.
- GPS Patch on Quadcopter
  The example considers the antenna placement of a GPS patch antenna on a quadcopter.
- EMC Coupling
  The example considers the coupling between a typical monopole antenna and a loaded transmission line above a ground plane.
  - Example Overview
    Consider the coupling between a monopole antenna and a loaded transmission line above a ground plane.
  - Topics Discussed in Example
    Before starting this example, check if the topics discussed in this example are relevant to the intended application and experience level.
  - Example Prerequisites
    Before starting this example, ensure that the system satisfies the minimum requirements.
  - Creating the Model in CADFEKO
    Create the model geometry using the CAD component, CADFEKO.
  - Launching the Solver
    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.
  - Viewing the Results in POSTFEKO
    Display the model as well as the results using the post-processor component, POSTFEKO.
  - Final Remarks
    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.
- Waveguide Power Divider
  The example considers the transmission and reflection coefficients of a waveguide power divider.
- Optimisation of Bent Dipole and Plate
  The example considers the optimisation of the gain of a bent dipole in front of a plate.
Examples
The Feko Example Guide contains a collection of examples that teaches you Feko concepts and essentials.
Introduction to Feko
Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses involving 3D objects of arbitrary shapes.
CADFEKO
CADFEKO is used to create and mesh the geometry or model mesh, specify the solution settings and calculation requests in a graphical environment.
POSTFEKO
POSTFEKO, the Feko post processor, is used to display the model (configuration and mesh), results on graphs and 3D views.
EDITFEKO
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.
Feko Solution Methods
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.
Optimisation in Feko
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 Utilities
The Feko utilities consist of PREFEKO, OPTFEKO, ADAPTFEKO, the Launcher utility, Updater and the crash reporter.
Description of the Output File of Feko
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.
Feko Application Macros
A large collection of application macros are available for CADFEKO and POSTFEKO.
Scripts and Application Programming Interface (API)
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.
Appendix
Reference information is provided in the appendix.

Launching the Solver

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.

Launch the Solver using one of the following workflows:
- On the Solve/Run tab, in the Run/Launch group, click the Feko Solver icon.
- On the application launcher toolbar, click the Feko Solver icon in the group.
- Press Alt+4 to use the keyboard shortcut.

If the model contains unsaved changes, the Save Model dialog is displayed.

Click Yes to save the model and to close the Save Model dialog.

The Feko Solver is launched and the Executing runfeko dialog is displayed. The dialog gives step-by-step feedback as the simulation progresses.

Click Details to expand the Executing runfeko to view the step-by-step feedback.
