Effective Antenna Aperture Calculator
The effective antenna aperture/area is a theoritical value which is a measure of how effective an antenna is at receiving power. The effective aperture/area can be calculated by knowing the gain of the receiving antenna.

Where,
Ae = Effective Antenna Aperture
λ = Wavelength = c/f (where f = frequency, C = speed of light)
G= Antenna gain (Linear Value)
In the above formula, the Gain is assumed to be a linear value. However if Gain is in dB, then we could need to convert it from dB to a linear value to use in this formula. Alternatively, we could use the formula below. This assumes gain is in dB.
