The Antenna Object

The Antenna object models the properties and behavior of an antenna. Select one or more of the following to model an antenna and impose constraints:

Property	Description
Definition	Define the characteristics of the antenna.
Orientation	Specify the orientation of the antenna coordinate frame relative to the coordinate frame of the parent object.
Refraction	Model atmospheric refraction.
Processing Delay	The summed time values of the processing delays specified by each object in the strand plus the light time delay between object pairs in the strand. The light time delay between object pairs is computed simply based on the objects positions divided by the speed of light.
Description	Record useful information about the antenna.

Property	Description
Contours	Define the display of contour lines and antenna patterns.
Boresight	Define the display of boresight graphics.

Property	Description
Attributes	Control the display of contour lines and antenna patterns.
Vector	Control the display of vectors and other geometric elements related to the antenna.

Property	Description
Active	Impose constraints on access from the following available constraint categories for an Antenna object: Basic: The most commonly used constraints Angle: Constraints that involve an angular measure Geometry: Constraints that use a geometric measure (other than angle), such as range, altitude, and grazing altitude Analysis Workbench (AWB): Constraints that involve an Analysis Workbench (AWB) component (Angle, Calculation Scalar, Condition, or Vector) Central Body: Constraints involving the location of the Sun, planets, and moons Plugins: Your own plugin constraints, which compute a plugin-defined metric that you define Temporal: Constraints related to specified time-of-day or time intervals
Settings	Select access constraint conditions that apply generally to access computations involving an Antenna object.

Property	Description
Environment	Apply environmental factors that affect the performance of a communications link or a radar system.
