We are looking for a solution to operate several RI-STU-MRD2 devices with a small distance.
We use up to 16 devices with seperate antennas and the distance between them is 20 cm.
We use round antennas with Diameter of 160mm that are mounted on plastic tube.
In each of the tubes move pneumatic tube containers with Transponders.
We have the phenomenon that the devices influence on mutually.
We need a solution(antanna design?) that only will detect tronsponder from that single tube and not from the neighbour tube.
