Even if the antennas are connected to a processor unit, the minimum distances for the following
configurations should be respected to prevent unwanted interaction:
– Two antennas installed beside one another
– Two antennas installed back to back
A minimum distance of 50 cm from metallic components or polar liquids must be maintained to
prevent the antenna from detuning and avoid backscatter from strong electromagnetic fields.
Mounting data carriers directly to metal surfaces can drastically reduce the reading range.
Distances of at least 15 mm from the metal surface can improve the reading performance
considerably, depending on the antenna design.
To prevent the data carriers from detuning, the minimum distance between two data carriers
should not be less than 50 mm.
