Directional Radiation Pattern Of The Transponder On Metallic Surfaces - Siemens SIMATIC RF600 System Manual

7.7.3.6

Directional radiation pattern of the transponder on metallic surfaces

It is recommendable to align the transponder parallel to the transmitting antenna. If,
however, the transponder including the metallic carrier plate is tilted, the reading range will
be reduced.
Rotation about the polarization axis or orthogonal to the polarization axis

Note
Please note that the directional effect is dependent on the size of the metal surface. The
larger the metal surface, the larger the directional effect.
