IEEE 1979 Antenna Pattern

The IEEE 1979 antenna type model extends the external gain pattern data formats to use measured antenna gain data using the IEEE1979 standard.

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.
External Filename	The path and name of the file that contains the antenna gain data. View a format and example of the IEEE1979 file.

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.

External Filename

The path and name of the file that contains the antenna gain data. View a format and example of the IEEE1979 file.

Reloads the antenna data from the external file.

You can specify either a rectangular coordinate system or a polar coordinate system for this antenna.
