RDIF Applications
Besides the suppression and control of EMI issues, FAM can be a solution for RFID devices as well. FAM is highly suitable for LF (125 KHz) and HF
(13.56 MHz) bands. FAM can deal with complex issues such as when the RFID Reader/Writer or RFID tag is attached to a metal surface. When
used in this way FAM can reduce design complexity and significantly lower the total cost of ownership.

LH/HF RDIF on metal application
When a RFID tag or RFID reader/writer is attached to a metal surface, the read distance will become much shorter than expected. The traditional
solution is to increase the space between the RFID antenna and the metal but this can be detrimental when a thin device is desired. FAM can be
an excellent solution to improve the read distance for both LF (125/134.2KHz) and HF (13.56MHz) bands. FAM is inserted between the RFID
antenna and the metal surface to give an improvement of read distance of up to 80%. This can significantly improve the device footprint and
overall efficiency.
Frequently asked questions
How to use FAM with an RFID tag?
Place the cut FAM pad into the cavity and ensure good adhesion. When attaching to a metal surface FAM should not be attached to the antenna
side
How to use FAM for RFID reader/writer applications?
Insert the pre-cut FAM pad between the antenna and PCB. The antenna side should not be attached to the metal surface directly.
Can I use FAM for UHF RFID applications?
FAM works well in LF/HF RFID applications but is not suitable for UHF RFID (Electric-field) applications
How do I select the correct FAM thickness?
FAM is available in a number of standard thicknesses. T-Global engineers can offer application advice for design and engineering applications
What FAM dimension should I use?
The FAM pad should cover the entire RFID antenna area for optimum performance
Are the faces of FAM the same?
Unless an adhesive is applied there is no need to mount the FAM pad in a specific orientation.
