How to Calculate Directive Gain?
Directive Gain calculator uses Directive Gain = (4*pi)/(Beam Width in X-plane*Beam Width in Y-plane) to calculate the Directive Gain, Directive Gain is measure of the ability of an antenna to concentrate energy in a particular direction. It is also sometimes referred to as Directive Gain and this is descriptive of the antenna pattern. Directive Gain is denoted by G_{d} symbol.
How to calculate Directive Gain using this online calculator? To use this online calculator for Directive Gain, enter Beam Width in X-plane (θ_{b}) & Beam Width in Y-plane (φ_{b}) and hit the calculate button. Here is how the Directive Gain calculation can be explained with given input values -> 66.0367 = (4*pi)/(0.426733002112533*0.445931623884467).
