Antenna Setup: Tunnel for three orientations of Transponders with six antennas
2.1 Project notes
The antenna configuration described allows detection of tags moving through the horizontally
capture area of the RFID-Tunnel. The tag orientation is non-critical. The tags are detected along a
horizontal axis of motion in certain regions within the RFID-Tunnel. The area of detection depends
on the tag orientation.
The size of the three-dimensional capture area of the antennas is shown in the sketch below.
Notes:
Note that the entire capture area of the RFID-Tunnel is larger than the three-dimensional
area shown in the drawing. This means there are tag orientations in which the tag can be
detected outside the capture area.
If multiple RFID-Tunnel are arranged with short distances between each other, these will
mutually interfere with each other. The Readers for the respective RFID-Tunnels must then
be synchronized and if necessary be shielded.
