FA Card
This card is used to define a finite antenna array which includes mutual coupling and edge-effects.
On the Home tab, in the Planes / arrays
group, click the 
Array (FA) icon.
Figure 1. The FA - Finite array analysis dialog, with Planar/linear layout selected.
Parameters:
- Solve model using the domain Green’s function method (DGFM)
- If this option is selected, the DGFM will be used in the analysis of the finite antenna array. Not checking this option will result in the creation of the geometry and excitations only.
- Deactivate coupling between domains
- If this option is checked, mutual coupling will not be considered in the DGFM.
