Effective Antenna Aperture Calculator
The effective antenna aperture/area is a theoretical 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. Here we will calculate the effective antenna aperture of an antenna.

- Ae = Effective antenna aperture in m2
- λ = Signal wavelength in meter (m) = c/f (where f = signal frequency, C = speed of light = 2.998 × 108)
- G = Antenna gain (Linear value)
The effective antenna aperture (Ae) of an antenna is the area presented by the antenna to receive or transmit the electromagnetic wave. Thus, if the effective antenna aperture increase, the gain of the antenna will increase.
The gain of the antenna represents the maximum radiation intensity in a given direction (or absorbs incident power from that direction) when compared with a theoretical isotropic antenna.
As per antenna theory, the relation between the gain (G) of the antenna and antenna aperture (Ae) is given by:
Therefore, the effective antenna aperture is:
