Antenna Gain Calculator
English

The gain of an antenna (dbi) in a given direction is the amount of energy radiated in that direction compared to the energy an isotropic antenna would radiate in the same direction when driven with the same input power. Simply enter the efficiency, wave length, physical aperture area to calculate the gain or frequency of antennas.
