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.
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.
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.
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.

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.
Tip: Find the examples in the <FEKO_SHARED_HOME> directory:
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.
Limitations of Generate Antenna Array Macro
The Generate antenna arrayapplication macro has several limitations on how the base element is defined and the amplitude distribution.
