STK Antenna Models | External Antenna Models

Antenna Script Plugin Pattern

The antenna script plugin type is for external dynamic antenna gain models, written in MATLAB, Perl, or a VBScript scripting language.

Field	Description
Design Frequency	The frequency of the antenna. For an embedded antenna on a receiver, transmitter or radar, this value corresponds to the Frequency entered on the Model Specs tab for the transmitter or receiver and the Transmitter Specs tab for the Radar. For an antenna linked to a receiver, transmitter, or radar, the Antenna Design Frequency value gets overridden by the Frequency value set on the Model Specs tab for the transmitter or receiver, and the on the Transmitter Specs tab for the Radar. However, when computing the antenna's gain matrix (or a link budget, etc.) from one of the objects linking to the antenna, that other object's frequency settings override the antenna's Design Frequency setting.
Script Filename	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 Reload.

Description

Design Frequency

The frequency of the antenna.

For an embedded antenna on a receiver, transmitter or radar, this value corresponds to the Frequency entered on the Model Specs tab for the transmitter or receiver and the Transmitter Specs tab for the Radar.

For an antenna linked to a receiver, transmitter, or radar, the Antenna Design Frequency value gets overridden by the Frequency value set on the Model Specs tab for the transmitter or receiver, and the on the Transmitter Specs tab for the Radar. However, when computing the antenna's gain matrix (or a link budget, etc.) from one of the objects linking to the antenna, that other object's frequency settings override the antenna's Design Frequency setting.

Script Filename

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 Reload.

For information on scripting in STK, see the Engine Plugin Scripts topic in the Programming Interface Help, which is accessible from the Help menu. 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, Perl, 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.
