Pattern File Antenna

This option allows the user to introduce several files (at different frequencies) that define the radiation pattern. Firstly, the user has to import a radiation pattern file using the Import DIA file option of the Antenna menu.

Figure 1. Add Pattern File Antenna panel

The following parameters may be edited:

Set Radiation pattern file
Click on the Add button to add the imported file to the table where it is possible to specify the frequency, the type and the polarization of the file.
the amplitude and phase of the antenna.
Position - Coords
location of the antenna (X, Y and Z).
Orientation - Director cosines
orientation of the antenna coordinate system related to the absolute coordinate system.
Relative to reference plane
if this check box is selected, the position of the radiation pattern is relative to the reference plane.

The required format of the radiation pattern file is described in DIA Files.
