Antenna diagram for RF615R (FCC)
The following radiation diagrams show the directional characteristics of the internal antenna
of the RF615R (FCC) reader. For the spatial presentation of the directional characteristics,
the horizontal plane (azimuth section) as well as the vertical plane (elevation section) must
be considered. This results in a spatial image of the directional radiation pattern of the
antenna.
