Antennas often consist of arrays of contributing elements, either with direct feeds for each element or via indirect coupling. Designers have to consider not only the characteristics of the individual elements, but also for the entire array. Depending on the complexity of the array such analyses can become computationally very expensive.
FEKO contains various techniques for the efficient modeling of antenna arrays during the design process. The application and advantages of techniques such as periodic boundary conditions (PBC), the domain Green's function method (DGFM) and equivalent sources for efficient array modeling will be demonstrated.
