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.

无线通信遍及一切，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。如果任何东西都是无线的（与有线相反），天线总是需要的。毫无疑问，对天线产品的需求，特别是其日益复杂的版本，将在未来几年增加。随着天线性能复杂性的增加，确认给定天线是否满足所需性能所需的测量套件也增加。天线的详细测试非常耗时。主要贡献者是在这种测量期间与被测天线或采集探头的三维运动相关的采集时间。如果可以减少测试时间，则可以减少天线开发时间，从而提高竞争力。本研究提出一种方法，以减少测试时间时，广泛使用的球面近场测量技术用于天线测试。
