# 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 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.
