4 Optimal orientation of the antenna to the moving direction of the transponder
The antenna should be mounted as close as possible at the site of the transponder. As a rule a paralleI ori-
entation of the antenna to the transponder is favourable in regard of the reading range.

Figure 4.1: Optimal orientation transponder - antenna
The reading field is a complex three-dimensional function which is relevantly influenced by the orientation
of the transponder. With parallel orientation (see Figure 4.1) and low interference the reading field in
front of the antenna (shown in Figure 4.2) results.
