Altair Feko is the high-frequency solver in the Altair Electromagnetics portfolio. It is used extensively in various industries for antenna design and placement. The ability to hybridize both full-wave and asymptotic solvers allows the program to tackle electrically large problems and a wide range of applications such as RF, scattering, and electromagnetic compatibility. It stands out from the competition through its ability to export data to WinProp for wave propagation and radio network planning.

Antenna Design and Placement-1

Antenna Design

Altair Feko is used to design a very wide range of antenna types from wire antennas, microstrip, horn, aperture, lenses, reflector and conformal antennas. Also, phased arrays with a dedicated solution for windscreen antennas.

Antenna Placement and Coupling

Installed antenna performance is heavily dependent on antenna placement and integration. Altair Feko's ease of use makes it the best-in-class solution for placement and coupling.


Radomes, Including FSS

Altair Feko™ provides newFASANT models, the fastest solution to analyze radomes, including large electrical and frequency selective surfaces.

Radio Frequency Interference

From interferences between multiple transmitters and receivers in a site, broadcasting stations and aeronautical equipment or wireless networks Feko enables customers to anticipate,  mitigate RF interference effects including intermodulation, harmonics, antenna coupling, transmitter spectrum, receiver selectivity and blocking.


Electromagnetic Compatibility

Altair Feko™ is an extremely capable solution for EMC/EMI applications, and is trusted by industry experts as a valuable solution for immunity and emissions analysis involving cables, antennas and other devices. It can simulate EMI shielding, electromagnetic pulses, natural occurrences like lightning, HIRF, in addition to reverberation and anechoic chambers.





Key Capabilities


  • Run analysis for wireless connectivity, electromagnetic compatibility (EMC), antenna simulation and placement, radar performance, radome and urban wireless coverage.
  • Multiple solvers included that expand well beyond high frequency analysis.  Other solutions included include cable modeling, collocation interference, ultrasonic systems and virtual test drives/flights.
  • Hybrid solver solutions included make complex and large electrical problems easy to solve.
  • Feko is consistently adding new features to enhance the capabilities of the existing tool.  In the last few years, Altair WRAP for spectrum management, Altair Winprop for wireless coverage and newFASANT for radome modeling have been added.
