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:
“And meanwhile we have gone on living,
Living and partly living,
Picking together the pieces,
Gathering faggots at nightfall,
Building a partial shelter,
For sleeping and eating and drinking and laughter.”
—T.S. (Thomas Stearns)
“For what shall it profit a man, if he shall gain the whole world, and lose his own soul?”
