Effective Antenna Area
The following 4 diagrams show the intensity of the reception voltage over the area of
the antenna reading side for different reading distances. The scaling of this voltage
corresponds to the sum voltage S output by the antenna (refer to Table 20 on page
31). As long as this voltage is > 200, transponder codes are correctly received.
