Figure 8:
Optimal position of the transponder above the antenna (static)
Figure 9: Disadvantageous motion paths of the transponder over the antenna
A transponder has to be long enough in the active reading area to achieve a reliable reading result. The max-
imum reading distance will be achieved only in stationary operation. The reading range is reduced with a
transponder in motion. Therefore the transponder has to be passed closer at the antenna.
