Measuring Swept Return Loss
The plot in Figure 3-7 is for a cellular band antenna, swept from
800 MHz to 999 MHz. The plot (and the text above it) indicates that the
maximum return loss is at 885.4 MHz. This is the point where the
antenna is radiating the maximum amount of signal being fed into it
from the return loss bridge, and therefore the Test Set is receiving the
least amount of reflected (returned) energy back.
