Wide Range Antenna WRA 7070
For classic far-field applications with large reading distances, the Wide Range Antenna WRA 7070 is the best choice.
It is the standard antenna for many applications because it features an optimal axial ratio for circular polarisation. This
means that all transponders can be detected regardless of their orientation.
This makes the antenna the ideal selection for logistics and production applications, but also for vehicle detection.
The WRA 7070 is also available in a KRAI version. While the standard antenna has only one circular polarisation (RHCP =
right hand circular polarised), the KRAI version of the WRA 7070 allows 4 polarisations to be selected. In addition to the
two circular polarisations (LHCP/RHCP), the linear polarisations - vertical and horizontal - can also be used.
With the two circular polarisations, the reading performance can be increased. This is all the more evident the more
metal is in the environment and the more the RFID signals are diffused. The linear polarisations can be used to separate
transponders and also serve to increase the reading performance.
In addition, with the KRAI version of the WRA 7070, up to 4 multi-colour LEDs can be controlled, thus providing addi-
tional feedback for the user with a passive antenna.
