Antenna effective area
The antenna effective area A W (also effective antenna area or antenna absorption area ) is a characteristic of receiving antennas . It determines which electrical power P is drawn from the electromagnetic field at a given power density S of the field:
From the supplied power z. B. determine which voltages occur with a known electromagnetic field S at the antenna connection.
The relationship between the maximum effective antenna area and antenna gain G at a known wavelength λ can be derived from the reciprocity law :
