The new generation of 5G Massive MIMO array antennas and phased array antennas in the fields of satellite communication have the characteristics of narrow beam and high gain, because the truncation angle of the scanning surface does not need to be ≥ 90°, and horizontal planar near-field measurement is a better choice.
Technical advantages
Compared to the far-field, the horizontal planar near-field enables accurate measurement of 3D beam pointing in a more compact test space
In addition to the conventional radiation pattern test, the amplitude and phase data acquisition of the antenna unit can also be completed efficiently
The scanning hardware structure is relatively simple and the deployment cost is low, which can be used for R&D design verification and is also suitable for batch deployment of production lines for unit calibration
