A technique for spherical near-field antenna test time reduction

从个人之间的通信，到系统和设备之间的通信，再到数据计量，无线通信无处不在。如果有什么是无线的（而不是有线的），天线总是需要的。毫无疑问，对天线产品的需求，尤其是越来越复杂的天线产品，在未来几年将会增加。随着天线性能复杂性的增加，确认给定天线是否满足要求性能所需的一整套测量方法也在增加。精密的天线测试非常耗时。主要影响因素是在测量过程中与被测天线或采集探头的三维运动有关的采集时间。如果这个测试时间可以减少，那么天线的开发时间就可以减少，从而提高竞争力。本研究提出了一种采用球面近场测量技术进行天线测试时减少测试次数的方法。

Wireless communications pervades everything, from communications between individuals, to communications between systems and equipment, to data metering. If anything is wireless (as opposed to wired), antennas are always required. There is little doubt that the need for antenna products, especially increasingly sophisticated versions thereof, will increase in the years to come. As antenna performance complexity increases, so too does the suite of measurements needed to confirm whether a given antenna satisfies the required performance. Elaborate testing of antennas is time-consuming. The principal contributor is the acquisition time related to the three-dimensional movement of the antenna under test, or the acquisition probe, during such measurements. If this test time can be decreased then antenna development times can be decreased, resulting in increased competitiveness. This research proposes a way to reduce test times when the widely used spherical near-field measurement technique is used for antenna testing.
