It is intended for users with little or no experience with Altair FEKO. The various as-pects of the different FEKO components are discussed as they are encountered. A demonstrationmodel of a completed horn antenna with results is used as an example. The model will not beconstructed as part of this demonstration, but instead be used to demonstrate tasks that are oftenrequired in the FEKO horn model is similar to the model used in the demo video1. It is recommended that thedemo video be watched before working through this 1-1: Illustration of the horn Before starting the exampleBefore starting this example, please ensure that the system satisfies the minimum requirementsbefore starting.

8 A user should also ascertain whether the topics presented in this example arerelevant to the intended application and FEKO experience topics demonstrated in this example are: General program flow of the FEKO. Launching CADFEKO. The CADFEKO layout. The POSTFEKO layout. Viewing the simulated far field and near field results in demo video is a short movie demonstrating the solution of a horn antenna similar to the example that isshipped with the Altair FEKO installation. It may be found in thedocsubdirectory of the Altair FEKO installation. ForWindows installations, this file is , which may be executed directly or from the Windows start menu. OnLinux installations, the demo is opened inside This demo video, as well as other FEKO demonstrationvideos may be viewed on our 2015 FEKO Getting StartedRECTANGULAR HORN ANTENNA PROJECT1-2 The requirements for this example are listed below.

9 FEKO or later should be installedawith a valid licence. It is recommended that the demo video be watched before attempting this example. This example should not take longer than 30 minutes to the FEKO Installation Guide to install Altair working through this example, the steps should be followed sequentially, otherwise expla-nations may seem to be out of Different FEKO components and workflowThe components that are most visible to users are CADFEKO, POSTFEKO and the FEKO is the CAD component where the model is created and solution settings are the model has been created, it needs to be meshed and then the kernel is run to producesimulation results. The results are then viewed, manipulated and exported in the post processor,named POSTFEKO. After viewing the results it is often required to modify the model again inCADFEKO and then repeat the process until the design is complete.
