Feko Application Macros
A large collection of application macros are available for CADFEKO and POSTFEKO.
CADFEKO Application Macros
A collection of Lua application macros are available to automate repetitive tasks in CADFEKO.
Generate Antenna Array
The application macro allows you to create an array of elements. Specify the number of elements and offset between the elements, or import the coordinates from file to create an irregular-spaced array. For the array amplitude distribution, select a mathematical distribution (such as cosine) or import the magnitude and phase for each element from file.

Release Notes

Get Started
The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
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.
- Application Macros
  An application macro is a reference to an automation script, an icon file and associated metadata.
- Application Macro Library
  The application macro library allows commonly used application macros to be stored in a repository.
- CADFEKO Application Macros
  A collection of Lua application macros are available to automate repetitive tasks in CADFEKO.
  - Transfer User Configurations
    This application macro transfers settings and application macros between different versions of Feko. This may be useful if you have customised one installation of Feko and want to use the same settings in a concurrent installation.
  - Generate Antenna Array
    The application macro allows you to create an array of elements. Specify the number of elements and offset between the elements, or import the coordinates from file to create an irregular-spaced array. For the array amplitude distribution, select a mathematical distribution (such as cosine) or import the magnitude and phase for each element from file.
    - Defining a Linear or Planar Antenna Array
      Use the application macro to create a linear or planar antenna array from a specified base element.
    - Defining an Irregular-Spaced Array
      Use the application macro to create an irregular-spaced antenna array from a specified base element.
    - Limitations of Generate Antenna Array Macro
      The Generate antenna array application macro has several limitations on how the base element is defined and the amplitude distribution.
  - Compare CADFEKO Models
    The application macro allows you to compare two CADFEKO models to find the differences between the two models.
  - ***
    The Create Edge Port application macro creates an edge port on a finite substrate.
  - Other CADFEKO Application Macros
    A collection of smaller CADFEKO application macros are available, but these macros do not include step-by-step instructions.
- POSTFEKO Application Macros
  A collection of Lua application macros are available to automate repetitive tasks in POSTFEKO.
- Shared Application Macros
  A collection of Lua macros are available to automate repetitive tasks where the workflow span both 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.

Generate Antenna Array

The application macro allows you to create an array of elements. Specify the number of elements and offset between the elements, or import the coordinates from file to create an irregular-spaced array. For the array amplitude distribution, select a mathematical distribution (such as cosine) or import the magnitude and phase for each element from file.

The array tool application macro has additional functionality when comparing to the Finite array tool¹ in CADFEKO that allows you to create custom and complex antenna arrays with ease. Create a .cfx file that contains the base element (antenna). Then use the application macro to copy the base elements (including all its ports, sources and loads) to create the array. Each source and load are given a unique name, allowing you to modify any source or load for an array element after the application macro was run. You can also specify the configuration to which the sources and loads should be copied.

Figure 1. The antenna array created by copying the base element. Each element has a unique label for the port, source and load.

Tip: Find the examples in the <FEKO_SHARED_HOME> directory:

<FEKO_SHARED_HOME>/installedapplicationmacrolibrary/CADFEKO/ArrayTool/examples.

¹ The Finite antenna array tool in CADFEKO copies the base element, but the same sources and loads as used for the base element, are used for all antenna array elements. For the array amplitude distributions, you can either specify the uniform amplitude distribution or specify the magnitude and phase per element.
