Introduction to the RIFD System
7.2.2 ©KRAI SMSH (Smart Shelf) Antenna
Fig. 4: ©KRAI smart shelf antennas connected to the reader (cascaded)
Up to 8 ©KRAI smart shelf (SMSH) antennas can be cascaded per reader port; 8 antennas x 4 ports = 32 SMSH antennas
in total.
The SMSH 3030 @KRAI slave antenna was developed for applications in the field of point of sale, smart shelf applica-
tions and Kanban solutions. The antenna is characterised by an extremely homogeneous read zone, which is emitted by
the high front-to-back ratio. Therefore, it is suitable for static detection of multiple transponders. Due to the extremely
thin design, the antenna module can be integrated into different applications.
The antenna is equipped with an intelligent bypass circuit that allows for cascading up to 8 SMSH antennas per reader
port. The control is done by a RRU 4xxx Kathrein RFID reader. The ©KRAI control signals are transmitted via the standard
antenna cable.

Tip
Note that the ©KRAI SMSH high-gain antennas have a read range of up to 3 m.
The ©KRAI SMSH standard antennas read transponders at a distance of up to 1 m.
Tip Note that the SMSH high-gain antennas (order no. 52010260) and SMSH standard antennas (order no.
52010219) do not have ©KRAI and cannot be cascaded.
