Using this Antenna Efficiency Calculator you can calculate efficiency of your antenna. Just provide gain, diameter, and frequency to calculate. the in most of the situations, I faced very difficulty in calculations, but now it is solved.
Antenna Efficiency Calculator
Calculate antenna efficiency from gain, diameter, and frequency.

Efficiency (K): —
Efficiency (%): —
Antenna Efficiency Formula
K = (ฮปโ/ฯD)2*1010/Gโ
- GdB is Antenna Gain in dB
- K is Antenna efficiency
- D is the Diameter of the antenna (in meters)
- ฮป is the Wavelength in meters and it is calculated as ฮป=c/fโ
- c is 3ร108 (speed of light)
- f is the frequency.
