Partial gain is calculated as power gain, but for a particular polarization. It is defined as the part of the radiation intensity corresponding to a given polarization, divided by the total radiation intensity of an isotropic antenna.
where and represent the radiation intensity in a given direction contained in their respective E field component.
As a result of this definition, we can conclude that the total gain of an antenna is the sum of partial gains for any two orthogonal polarizations.

Famous quotes containing the words partial and/or gain:
“You must not be partial in judging: hear out the small and the great alike; you shall not be intimidated by anyone, for the judgment is God’s.”
—Bible: Hebrew, Deuteronomy 1:17.
“The first place he went into was the Royal Exchange .... where men of all ages and all nations were assembled, with no other view than to barter for interest. The countenances of most of the people showed they were filled with anxiety; some indeed appeared pleased, but yet it was with a mixture of fear.... [David] resolved to stay no longer in a place where riches were esteemed goodness, and deceit, low cunning, and giving up all things to the love of gain were thought wisdom.”
