Reflection

Reflection in the RFID context refers to the bouncing back of electromagnetic waves from surfaces, especially metal. As a result, the signal does not travel only directly to the tag or the reader, but also by indirect paths. This multipath propagation can cause signals to reinforce, weaken or interfere with one another. That affects the stability of detection and changes the read zone of a system. Reflection is therefore an important factor in the placement of RFID antennas and other components in the surrounding area. Taking reflection into account improves the reliability of read processes at gates, conveyor lines and workstations.
