This antenna model describes the well-known dipole antenna or doublet. It consists of two identical conductive elements, which are bilaterally symmetrical.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Extends

Name	Type	Description
AntennaBase	compound module	This module servces as the base module for antenna models.

Parameters

Name	Type	Default value	Description
mobilityModule	string		the path to the mobility module relative to this module, only used if no mobility submodule is present
numAntennas	int	1	the number of antennas in the antenna array
length	double		the length of the dipole antenna
wireAxis	string	"z"	allows matching the antenna radiation pattern (IAntennaGain) to the visual representation, antenna orientation is determined by the antenna's mobility model the default value is Z axis, so that antenna mobility models are not required when antennas are approximately positioned in the same plane
