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:
“We were soon in the smooth water of the Quakish Lake,... and we had our first, but a partial view of Ktaadn, its summit veiled in clouds, like a dark isthmus in that quarter, connecting the heavens with the earth.”
