The formula to calculate the Antenna Factor (AF) is:
\[ AF = 20 \log_{10}\left(\frac{FS}{V}\right) \]
Where:
The antenna factor is a measure used in electromagnetic compatibility (EMC) testing to relate the electric field strength to the voltage induced by that field in an antenna. It is a critical parameter for determining the performance of an antenna in a given electromagnetic environment. The antenna factor is typically expressed in decibels per meter (dB/m) and is used to convert measurements taken by an antenna into field strength values.
Let's assume the following values:
Using the formula:
\[ AF = 20 \log_{10}\left(\frac{10}{0.1}\right) = 20 \log_{10}(100) = 20 \times 2 = 40 \, \text{dB/m} \]
The Antenna Factor is 40 dB/m.
