Importing Array Parameters From File

Specify a file to import an array with a user-defined distribution, or to import an irregular-spaced array or both.

Figure 1. The Import array parameters dialog.

1. In the Filename field, browse for the file you want to import. The number of antenna array elements is determined from the specified file.
   Note:

   • If you have selected Custom array in Step 5, the file that you import must contain the X, Y and Z coordinates, amplitude, and phase (in degrees).

     For example (if you use comma-separated values):

     20, 30, 40, 1, 0
     25, 30, 40, 2, 20
     28, 30, 40, 5, 30

   • If you have selected Custom (import from file) in Step 1, the file that you import must contain the magnitude, and phase (in degrees), where the base element is the last element in the file.

     For example (if you use comma-separated values):

     1, 0
     2, 20
     5, 30

     Figure 2 illustrates the element order when importing the magnitude and phase from a file.

2. Under Delimiter, select the delimiter type used in the file to be imported from the following list:
   • Comma
   • Tab
   • Space
3. Click OK to close the dialog.

The application macro creates an array as specified.
