FIAFTA is valid for all kinds of antennas and is able to process the near-field data collected on an arbitrary grid.
The coupling matrix [parallel]C[parallel] takes care of the plane wave translations to the measurement points of the arbitrary grid.
Since FIAFTA can handle measurements on arbitrary grids, the valid angle of the radiation pattern can be significantly increased by utilizing adaptive sampling in planar and cylindrical measurements [33, 34].
Even FEM programs that use arbitrary grid element sizes require an increase in the number of elements around small structures.
A comparative analysis between the arbitrary grids was then conducted to interpret morphological changes across space.
