Effective Antenna Aperture Calculator

Effective Antenna Aperture is a measure of how effective an antenna is at receiving the power of radio waves. Aperture of an antenna is not directly related to its physical size. Use our online Effective Antenna Aperture Calculator just by entering the values of Frequency (λ) in MHz and Antenna gain (Gr) in dBi to calculate Effective Aperture (Ae) where the unit is m2.

Calculate Effective Aperture (Ae) with this simple online calculator. The effective area / aperture can be calculated by knowing the gain of the receiving antenna.
