ANT-450-RHS-SMA

Peak Gain

The peak gain across the antenna bandwidth is shown in Figure 5. Peak gain represents the maximum

antenna input power concentration across 3-dimensional space, and therefore peak performance, at a given

frequency, but does not consider any directionality in the gain pattern.

Return Loss

Return loss (Figure 4), represents the loss in power at the antenna due to reflected signals. Like VSWR, a

lower return loss value indicates better antenna performance at a given frequency.
