The simulation of broadband antennas can be very challenging due to the complexity of antenna geometries and the time it takes to simulate a wideband response. FEKO offers many features that may be applied to such problems:

  • Method of Moments (MoM) based simulation engine suitable for multi-scale geometries
  • Optimisation capabilities which can combine multiple goals and optimise according to data masks
  • Adaptive Frequency Sampling (AFS) for the adaptive interpolation of results over wide frequency bands, thereby limiting the number of frequency points that have to be simulated to obtain a wideband response.
