Patent number: 11322858Abstract: An antenna unit and an antenna array. The antenna unit includes M layers of cross metal patches, M layers of dielectric substrates, and a metal ground layer, where M is an integer greater than 1. In addition, an ith-layer dielectric substrate is disposed between an ith-layer cross metal patch and an (i+1)th-layer cross metal patch. The ith-layer cross metal patch, the ith-layer dielectric substrate, and the (i+1)th-layer cross metal patch are sequentially stacked, and i is an integer ranging from 1 to M?1. An Mth-layer cross metal patch, an Mth-layer dielectric substrate, and the metal ground layer are sequentially stacked. The antenna unit and the antenna array formed by units may have a good polarization feature, a relatively wide operating bandwidth, and a relatively good phase shift feature.Type: GrantFiled: June 11, 2020Date of Patent: May 3, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Qingming Xie, Long Li, Guoliang Cao, Rui Shi, Yang Geng

Patent number: 10879610Abstract: This application discloses an antenna apparatus, including an antenna array and an adjustable phase shifter. In each row of antenna elements in the antenna array, antenna elements on a same radio frequency RF channel are spaced by M antenna elements, where M is used to determine a quantity of beams in a first beam group and a quantity of beams in a second beam group, and M is an integer greater than 1. When the adjustable phase shifter is at a first angle, the first beam group is obtained; or when the adjustable phase shifter is at a second angle, the second beam group is obtained. This application discloses a beam adjustment method. In this application, a plurality of beams can be formed in a horizontal direction, and the beams are grouped by using an adjustable phase shifter, thereby effectively improving beam adjustment flexibility.Type: GrantFiled: December 5, 2019Date of Patent: December 29, 2020Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yannian Lou, Ni Ma, Wangjun Wu, Peng Chen, Jianping Zhao, Qingming Xie
