Kathrein offers the most comprehensive UHF RFID antenna portfolio. For applications in the read range up to 12 m, the WRA 7070 antenna is available for such application. The WRA 7070 antenna are characterised by a high antenna gain and at the same time very low axial ratio for circular polarization, for optimum reading of transpon- ders in all orientations, even at great distances. For dynamic requirements, where static antenna parameters are not sufficient for the application, this antenna is also available as a KRAI version. With this Kathrein RFID Antenna Interface, the 4 polarisations can be switched, and 4 LEDs can be activated without having to connect a power supply to the antenna. The antennas are ideal for gate and portal applications, but also for vehicle detection. It is the universal antenna for almost all requirements.
