6.3.6.3 Antenna pattern FCC
Directional radiation pattern FCC
The directional radiation pattern is shown for nominal alignment and a center frequency of
915 MHz.
Figure 6-19 Reference system
The half-power beam width of the antenna is defined by the angle between the two -3 dB
points (corresponding to half the power in relation to the maximum power). Which range (in
%) corresponds to the dB values in the patterns can be obtained from this table.
Note that the measurements presented graphically below were carried out in a low-reflection
environment. Low deviations can therefore occur in a normally reflecting environment.
