Finite Antenna Array Limitations

A finite antenna array or DGFM is not applicable to all models, but can significantly improve simulation speeds when it can be applied.

  • The DGFM is supported for MoM examples containing metallic triangles, wires and connections between them. Skin effect and dielectric / magnetic coatings are supported for metallic surfaces. Coatings and discrete loads are supported for wires.
  • Only a single FA card is allowed in the model.
  • The following is not allowed in conjunction with the DGFM:
    • General network, transmission line, network load or a cable load
    • VEP, FEM or FDTD solution method
Note: Interconnected or very closely coupled domains with a spacing less than λ 10 between array elements are not allowed.
