Cylinder type, Near field Antenna measurement system

Model No. anm02

As it combines the vertical direction of the probe antenna with the turn of the object antenna, and performs the near field measurement in the shape of a cylinder.
The result will be converted to far field.

Feature
The pattern behind the antenna can be measured by a cylinder scanning.
Fast measurement.
For example ) Vertical direction 256 point and Rotatory direction 180 point : 30 minutes
( Depends on the performance of the vector network analyzer. )
