Robust Plane Wave Generator Design in Small Anechoic Chamber Setup Using Parameterized Field Distribution Method

摘要

Plane Wave Generator (PWG) has attracted great interest in the industry and academia for 5G measurement, thanks to its low-cost and smaller system setup. One major concern in the small setup is its high reflectivity level, which might distort the quiet zone performance significantly. Meanwhile, it is critical that the quiet zone performance is insusceptible to system inaccuracies. In this paper, a new PWS strategy is proposed based on parametrized field distribution over an enlarged sampling area, which offers robust design and low reflectivity level. The effectiveness and robustness of the proposed PWS strategy is demonstrated in a numerical simulations.
