Abstract

Millimeter-wave technology has attracted a lot of attention from academia and industry, while millimeter wave antenna arrays are utilized in both base stations and mobile terminals to confront the issues of high loss and channel blockage. In addition, since the space in the mobile terminal is extremely limited, there is an urgent need for a very compact size, as well as a high wide beam scanning capability to achieve greater spatial coverage and reduce the number of millimeter wave antenna modules required. The purpose of this paper is to discuss the high- performance scanning techniques for millimeter wave antenna and array under the background of current solutions, and predict the future development of millimeter wave antenna, as well as its test system.

5G毫米波通信宽波束扫描天线阵列及近场测试系统
毫米波技术引起了学术界和产业界的广泛关注,但无论是基站还是移动终端都采用了毫米波天线阵列,面临着高损耗和信道阻塞的问题。此外,由于移动终端的空间极为有限,因此迫切需要非常紧凑的尺寸,以及高宽波束扫描能力,以实现更大的空间覆盖并减少所需的毫米波天线模块数量。本文的目的是在现有解决方案的背景下,讨论毫米波天线和阵列的高性能扫描技术,并对毫米波天线及其测试系统的未来发展进行预测。
