Figure 3
Detection areas, top view
Only a maximum of one transponder is allowed in the detection area of the antenna
at all times! The following image shows several transponders to explain the different
transponder positions.
Figure 4
Core area of the reading antenna with position impulse (top view)
The code of the transponder is read in both detection areas. For an additional Posi
-
Pulse to be triggered, the transponder must first have moved through area 1. The
maximum lateral offset to the antenna center is determined by line C. In this case,
the PosiPulse is generated as soon as the transponder reaches the crossing to the
data-free area D. Since both detection areas have a curved course, the point at
which a PosiPulse is triggered shifts the further away the transponder is from the
centre of the antenna (line A) (center deviation). The absolute values are given in sec
