作者提出了一种新颖的方法，可以显着减少天线测量时间并提高收集最相关信息的数据的效率。他们应用压缩感知方法来减少天线测量中的冗余，即将超表面添加到天线近场，并且由 FPGA 操纵单元以促进稀疏采样。实验结果表明，与传统的稀疏采样方法相比，该策略在满足测量误差的情况下可以减少至少56%的测量时间，在天线测量方面具有巨大的潜力。
The authors propose a novel method for significantly reducing antenna measurement time and increasing the efficiency of collecting the data which most is relevant information. They apply methods from compressed sensing which reduce redundancy in the antenna measurement, i.e. a metasurface is added to the antenna near‐field, and the unit cell is manipulated by a FPGA to facilitate sparse sampling. In comparison with the traditional sparse sampling method, experimental results demonstrate that their strategy can reduce the measuring time by at least 56% while satisfying measurement error and that it has considerable potential for antenna measurement.
