Antenna efficiency (%) (output) :

*Note: Enter values in INPUT boxes and Press CALCULATE button to check OUTPUTS.

Antenna diameter = 2.4 meter, Antenna Gain (dBi) = 43, Antenna frequency = 6000 MHz
OUTPUT: Antenna efficiency = 87.75 %

Antenna Efficiency Equation

Antenna Gain equation can be expressed as follows. From this equation, antenna efficiency can be calculated using above calculator. The equation of antenna efficiency is mentioned in the following figure. The inputs are antenna diameter, antenna gain and antenna frequency. G = 10*log10 ( K* ((π*D)/λ)2);
