Kathrein RFID Antenna Interface © KRAI
By using Kathrein © KRAI antennas, reading rates can be increased by 33% compared to simple circular
antennas.
The Kathrein-RFID Antenna Interface © KRAI consists of a digital control bus, which enables connection
between the RFID reader and the RFID antennas in order to allow control and regulation tasks in remote
antennas.
The phase control elements integrated in the © KRAI antennas enable static or dynamic adjustment of
antenna characteristics.
Due to this, four different polarizations can be selected for the new 70° Wide Range antenna (type 52010193
WIRA-70-KRAI-ETSI): RHCP / LHCP/ horizontal linear / vertical linear
One can choose between static polarization and automatic switch-over. As the Kathrein-RFID Antenna In-
terface © KRAI is transmitted over the standard antenna cable, no additional lead or connection is required
to control the new antenna types.
The Kathrein RFID © KRAI system permits the cascading of up to 8 SMSH antennas at a single antenna
port. This allows selective access to up to 32 individual antennas. This allows the reading result to be linked
to the antenna recognition (e.g. antenna 3 (5)) and be output.
With the new © KRAI product series Kathrein has introduced a revolutionary system.
