Specifying the Amplitude Distribution

Define the amplitude distribution for the antenna array.

Figure 1. The Import excitation values dialog.


  1. Under Amplitude type, select one of the following:
    • Uniform
    • Triangular
    • Cosine
    • Cosine-squared
    • Custom (import from file)
    Note: If you have selected Custom (import from file), continue to Importing Array Parameters From File.
  2. From the Apply amplitude type to drop-down list, select one of the following:
    • X axis
    • Y axis
    • X and Y axes
    Note: If only a single axis is specified1, a uniform distribution is applied to the second axis.
  3. [Optional] In the X direction field, specify the phase difference in degrees between the elements.
  4. [Optional] In the Y direction field, specify the phase difference in degrees between the elements.
  5. Click OK to close the dialog.
The application macro creates an array as specified.

1 For example, if a cosine distribution is applied to the X axis, a uniform amplitude is applied to the Y axis.
