What is the influence of the antenna alignment between RFID transponder and reader?

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.


All NeoTAG® transponders use single-axis transponder antennas. To achieve an optimal reading range, the magnetic fields of the reader antenna and the transponder antenna should be optimally aligned. The magnetic field generated in the reader antenna must produce an electrical voltage when flowing through the transponder antenna. In extreme cases, non-observance can lead to failure of the reading capability.
