The following general safety precautions should be considered when working with antennas:
Test Antennas for emission measurements (RX applications) do not generate any hazardous fieldstrength. For immunity testing and intentional generation of high fieldstrength the relevant emission and safety standards of the respective country must be considered (e.g. DIN VDE 0848).
The generated fieldstrength level can be estimated (free space propagation assumed) using the following equations.
F = 134.8 + gi + 10 log P -20 log D | |
Fieldstrength Level | F [dBµV/m] |
Power into matched antenna | P [W] |
lsotropic Gain | gi [dBi] |
Distance | D [m] |
F=104.8 + gi + p - 20 log D | |
Power into matched anrenna | p [dBm] |
