Quick guide to evaluate scan
area requirement
The required scan area is calculated according to the following
formula: Scan length = D + 2 L tg (
a )
Where:
-
a is the relevant data angle in far-field
- L, the distance between the probe and the AUT
- and D, the antenna size.
Sampling principle
Sampling step is based on the minimum measured
wavelength (
l
min
).
D
sampling
= ( l
