Abstract

This article presents a cost-effective, multifunctional far-field measurement system for high-directive and multibeam scenarios across the desired half-plane space of the 3D spherical range in millimeter-wave (mm-wave)/subterahertz (sub-THz) antennas. To realize these far-field measurement systems that can be widely utilized in various mm-wave/sub-THz applications, three representative measurement scenarios consisting of distinctly different antenna types and feed interfaces are exemplified and discussed under realistic constraints amid pragmatic antenna measurement challenges. In particular, cost-effective device-under-test (DUT) sample-fixturing methods and considerations of metallic weights for minimizing undesired vibrations in the rotary stage are utilized in the proposed far-field system to enhance the measurement capability and accuracy. Afterward, each measurement scenario is demonstrated using the exemplified samples. Finally, the main features and possibilities for further improvement are extensively discussed regarding the proposed measurement methods and system through a comparison with state-of-the-art references.

支持各种天线类型和馈电接口的精简毫米波和亚赫兹球形远场测量系统：天线测量系统用例

本文介绍了一种经济高效的多功能远场测量系统，适用于毫米波（mm-wave）/亚兆赫（sub-THz）天线所需的三维球面范围半平面空间的高指向性和多波束场景。为了实现这些可广泛应用于各种毫米波/次 THz 应用的远场测量系统，在实际的天线测量挑战中，在现实的限制条件下，对由截然不同的天线类型和馈电接口组成的三种代表性测量方案进行了示范和讨论。特别是，在拟议的远场系统中采用了具有成本效益的被测设备（DUT）样品固定方法，并考虑使用金属砝码最大限度地减少旋转台的意外振动，以提高测量能力和精度。随后，使用示例样品演示了每种测量方案。最后，通过与最先进的参考资料进行比较，广泛讨论了拟议测量方法和系统的主要特点和进一步改进的可能性。

期刊介绍： IEEE Antennas and Propagation Magazine actively solicits feature articles that describe engineering activities taking place in industry, government, and universities. All feature articles are subject to peer review. Emphasis is placed on providing the reader with a general understanding of either a particular subject or of the technical challenges being addressed by various organizations, as well as their capabilities to cope with these challenges. Articles presenting new results, review, tutorial, and historical articles are welcome, as are articles describing examples of good engineering. The technical field of interest of the Magazine is the same as the IEEE Antennas and Propagation Society, and includes the following: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications.
