FEKO (64-bit) 5.5

FEKO (64-bit) is a professional electromagnetic simulation and antenna design environment for modeling, analyzing, and optimizing RF and microwave components in 3D. The 64-bit edition leverages modern hardware and memory addressing to handle larger models with improved stability and performance.

What it’s used for:

• Antenna design and placement on complex platforms (vehicles, aircraft, ships, handhelds)
• Array design, beamforming, and MIMO studies
• Electromagnetic compatibility/interference (EMC/EMI) investigations
• Radar cross-section (RCS) and scattering analysis
• Waveguides, filters, and other microwave component design
• Shielding effectiveness and coupling assessments

Key capabilities:

• Multiple numerical techniques (full-wave and asymptotic) with hybrid workflows to cover a wide range of electrical sizes efficiently
• Integrated geometry modeling, meshing, and CAD import/export
• Parameterization, optimization, and design-of-experiments to refine performance
• Comprehensive post-processing for field visualization, radiation patterns, and S-parameters
• Scripting and batch execution for automation and repeatable workflows

FEKO (64-bit) is suited to RF engineers, researchers, and product teams in communications, automotive, aerospace, and defense who need accurate, scalable electromagnetic simulation.
