Member Function Documentation

◆ computeGain()

double inet::physicallayer::DipoleAntenna::AntennaGain::computeGain ( const Quaternion direction) const
overridevirtual

Returns the antenna gain in the provided direction.

The direction is determined by rotating the X axis using the given quaternion. The direction is to be interpreted in the local coordinate system of the radiation pattern. This way the gain depends only on the antenna radion pattern characteristics, and not on the antenna orientation determined by the antenna's mobility model.

For transmissions, it determines how well the antenna converts input power into radio waves headed in the specified direction. For receptions, it determines how well the antenna converts radio waves arriving from the specified direction.

Implements inet::physicallayer::IAntennaGain.
