1、Non-anti-metal tags are mounted on metal surfaces, buffer ≥20mm, and tag
performance can be retained above 80%；
2、When the anti-metal tags is directly mounted on the metal surface, it can still retain
more than 90% of the original performance;
Embedded metal mounting——anti-metal tags can be directly embedded in metal
applications,non-anti-metal tags are not recommended for embedded metal applications;
Free zone——Refers to the blank area around the tag when the tag is embedded in the
metal.
1、When the anti-metal tags is embedded in the metal installation without leaving a
free area, the tag performance can still be maintained above 90%;
2、If the non-anti-metal is embedded in the metal mounting surface, the free area a≥2X,
b≥2Y, c≥20mm must be reserved. In this case, the tag can retain more than 80% of the
original performance.
Fig 3.3.1 Tag Installation Environment Specification
3.4 Electromagnetic wave response in the UHF band
When electromagnetic waves propagate in the UHF band, they are constrained
by some environments (such as metals, walls, liquids, other signal transmitters,
etc.), resulting in reflection and mutual interference.This phenomenon may be
manifested by the fact that the electromagnetic wave signal expands the reading
range of the reader through metal reflection;it may also be that the
electromagnetic wave signal is interfered by other signals in the same frequency
band to reduce the reading range of the reader.
Due to these electromagnetic characteristics,it is extremely difficult to determine
the propagation path of the signal and its field strength when the reader is in a
multiple reflection environment.
In order to reduce the influence of reflection and interference on identifing tag,
it is recommended to appropriately reduce the transmit power of the reader.
In addition, when the ground is poor and the reader is installed on the metal, it may
affect the performance of the reader. Therefore, pay attention to the following points
when installing the reader in the metal environment:
Embedded metal mounting——Reserved buffer (buffer can add non-anti-metal
