Gain of Antenna Calculator

Antenna gain is a performance number which combines the antenna's directivity and electrical efficiency. It is the ratio of the power produced by the antenna from a far-field source on the antenna's beam axis to the power produced by a hypothetical lossless isotropic antenna. Given here is an online gain of antenna calculator to perform antenna gain calculation in dBi.

Antenna Gain Calculation in dBi

Result :

When no direction is specified, "gain" is understood to refer to the peak value of the gain. Usually, the antenna gain calculation is expressed in "decibels-isotropic" (dBi). Antenna gain is a metric that describes the performance of the antenna in converting input power into radio waves which are headed in a specified direction. Make use of this gain of antenna calculator to find the antenna power.
