rfid tag for metal surface

How do the RFID tags work on metal surface?

FR4 (Fire-Resistant 4) PCB RFID tags, which are often designed with a layer of FR4 material as part of their construction, are engineered to

improve RFID performance when used on or near metal surfaces.

FR4 PCB Material:

FR4 is a flame-retardant fiberglass material commonly used in the construction of circuit boards and electronic devices. In the context of

RFID on metal tags, a layer of FR4 material is integrated into the tag's design to act as a spacer or shielding layer between the RFID tag's

antenna and the metal surface.

Anti-Metal Design:

The FR4 layer helps minimize the interference and signal reflection caused by the presence of the metal surface. It isolates the tag's antenna

from direct contact with the metal, reducing the impact of metal interference.

RFID Tag Placement:

FR4 PCB RFID tags are typically attached to or embedded in items, equipment, or assets that need to be tracked, even when placed on or

near metal surfaces. The placement is crucial for ensuring that the FR4 layer is effective in mitigating metal interference.
