© KRAI CSB (Circular Switch Beam-) antenna
With the ©KRAI CSB-Antenna, build as a WiRa 30° antenna, the antenna beam can be switched static or dynami-
cally. The following settings are possible in any combination:
-
Antenna beam initial position (radiation 90°of the Antenna)
-
Antenna beam switched 35° to the left
-
Antenna beam switched 35° to the right
The orientation of switching is in the longitudinal direction of the antenna. On the connector side of the antenna the
position “RIGHT” is defined.
These CSB antennas are used to detect the movement of the transponder. This information will be transferred in
combination with the collected transponder is. With 5 antenna sweeps per second, two or more reads are used to
determine the direction of movement.
