What is the influence of the materials in which the NeoTAG® transponder is inserted?

Our product range of NeoTAG® HF RFID transponders/ RFID chips is constantly being expanded and new transponder versions are regularly added. In connection with the use of our transponders, we have compiled a large amount of background information on mounting, function, design, operating behaviour, etc. due to the many applications in which the products are used. As a supplement to our Product Information HF RFID Transponder data sheet, this article contains further technical explanations and application-supporting information.


Environments other than air influence the inductance of the transponder antenna coil and thus the operating resonance frequency due to altered magnetic conductivity. With plastics or other non-ferromagnetic materials, this is generally not critical.  

In a metallic environment, the field strength in the direction of the reading antenna is reduced from 100 % to approx. 20 %! This influence is shown quite well in the following simulation pictures:

Picture 11: Magnetic field strength of NeoTAG® in air

Metallic environments influence the operating resonance frequency differently depending on the material or alloy.
