Antenna Script Plugin Pattern
The antenna script plugin type is for external dynamic antenna gain models, written in MATLAB or VBScript.
| Field | Description |
|---|---|
| Design Frequency |
This is the frequency of the antenna. The antenna design frequency is independent of the operational frequency of a transmitter, receiver, or radar. Changing the frequency of a transmitter, receiver, or radar does not update an embedded antenna's design frequency, nor vice versa. The design frequency is solely used at antenna configuration time to compute the antenna size from its max gain or beamwidth settings. A mismatch between signal frequency and antenna design frequency typically causes performance degradation. |
| Script Filename | This is the path and file name of the user-defined script that defines the dynamic antenna gain model. The plugin script is not automatically reloaded after you make changes to it. To reload the script, click . |
For information on scripting in STK, see Engine Plugin Scripts. For instructions on the setup and use of plugin points, see Plugin Scripts. To develop a custom script from a sample template, select the appropriate sample plugin script, in MATLAB or VBScript, from <STK install folder>\CodeSamples\Extend\PluginScripts.
You can specify either a rectangular coordinate system or a polar coordinate system for this antenna.
