Antenna diagram for RF640R (FCC)
The following radiation diagrams show the directional characteristics of the internal antenna
of the RF640R (FCC) reader. For the spatial presentation of the directional characteristics,
the vertical plane (Azimuth section) as well as the horizontal plane (elevation section) must
be considered. This results in a spatial image of the directional radiation pattern of the
antenna with its main and auxiliary fields.
