•
The antenna conductors of the adjacent antennas should have a minimum distance of 2cm in
all directions. (see Fig. 8 )
Fig. 8
•
The size of the RFID-Tunnel sector should have approx. the size of the object which has to be
read + 5cm in height and width. In this case the length of the RFID-Tunnel is insignificant, but
the antenna sizes should match to each other.
•
The size of the antennas are depending on the distance of the Transponders to the antennas,
the size and the activating field strength of the Transponders and the distance between the
Transponders to each other.
•
The reading distance of one single antenna should be at least the half of the distance of the
two connected antennas of a the gate, when the reader is configured to half output power.
•
The antenna loop has always one turn only. (see Fig. 9)
