text: The power gain or simply gain G ( θ , ϕ ) {\displaystyle G(\theta ,\phi )} of an antenna in a given direction takes efficiency into account by being defined as the ratio of its radiation intensity U ( θ , ϕ ) {\displaystyle U(\theta ,\phi )} in that direction to the mean radiation intensity of a perfectly efficient antenna.
