Figure 24 shows the field alignment of a simple single loop antenna. This is the most simple and
most frequently used antenna type in the sector of

. Its size depends highly on the
reading range requirements and the place of application as well as the national limiting values.

The working range of an antenna depends very much on the position and alignment of the smart
label. A single loop antenna has the highest range in the centre of the antenna and if the smart
label is aligned parallel to the antennas surface.
