# Limitations of Generate Antenna Array Macro

The Generate antenna array application macro has several limitations on how the base element is defined and the amplitude distribution.

The following limitations should be noted:

- The base element consists only of the antenna. Geometry that does not form part of the array can be added after generating the array.
- The base element must be either a geometry part or model mesh part (the highest-level item in the model tree).
- When a mathematical distribution is only applied to a single axis, a uniform distribution is applied to the second axis.
- When defining an irregular-spaced array by importing from file, the number of elements is determined by the imported file.
