Figure 4.3: Disadvantageous motion paths of the transponder over the antenna
Because a transponder has to be long enough in the active reading area to achieve a reliable reading result.
The maximum 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.
5 Electrical supply of the antenna
The antenna is mounted perpendicular to the transfer direction of the keg's. It is important that the dis-
tance between the antenna housing and the feed rollers is about 1 cm. The antenna fixture must not be
made of metal.
The electrical interferences measured with the Mipos in laboratory are between 35mV and 50mV. At the
conveyor the electrical interferences are around 150mV under laboratory conditions.
