Patent number: 11757202Abstract: Embodiments of this application provide a pillar-shaped luneberg lens antenna and a pillar-shaped luneberg lens antenna array, and relate to the field of communications technologies, so that the pillar-shaped luneberg lens antenna can support dual polarization and improve a capacity of a communications system. The pillar-shaped luneberg lens antenna includes two metal plates that are parallel to each other and a pillar-shaped luneberg lens disposed between the two metal plates, the pillar-shaped luneberg lens includes a main layer and a compensation layer that are of the pillar-shaped luneberg lens, and the compensation layer is configured to compensate for equivalent dielectric constants of the main layer of the pillar-shaped luneberg lens in a TEM mode and/or a TE10 mode, so that distribution of equivalent dielectric constants of the pillar-shaped luneberg lens in the TEM mode and the TE10 mode is consistent with distribution of preset dielectric constants.Type: GrantFiled: May 28, 2021Date of Patent: September 12, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Xin Feng, Keli Zou, Guolong Huang

Patent number: 11251541Abstract: This application discloses a dual-polarized antenna, a radio frequency front-end apparatus, and a communications device. The dual-polarized antenna is a planar antenna, and a maximum radiation direction of the dual-polarized antenna is parallel to an antenna plane. A radio frequency circuit may be disposed at a side opposite to the maximum radiation direction of the dual-polarized antenna and located on a same circuit board as the dual-polarized antenna. A low profile feature is implemented, and the radio frequency circuit and the dual-polarized antenna do not need to be connected by using an interconnection plug, thereby reducing an insertion loss and reducing an assembly difficulty.Type: GrantFiled: July 8, 2020Date of Patent: February 15, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Chaoming Luo, Keli Zou, Guangjian Wang, Guolong Huang

Patent number: 10320090Abstract: An array antenna is provided. The array antenna includes at least one pair of interleaved TR antenna arrays in a continuous arraying direction, where the TX arrays and RX arrays of two adjacent TR antenna arrays are interleaved. This can effectively rectify discontinuousness of TX arrays and RX arrays in a discontinuous arraying direction in the prior art, and thereby reduce grating lobes or side lobes caused by discontinuous TX arrays and discontinuous RX arrays in an array antenna, so that performance of the array antenna improves.Type: GrantFiled: September 20, 2016Date of Patent: June 11, 2019Assignee: Huawei Technologies Co., Ltd.Inventors: Keli Zou, Tianxiang Wang, Hua Cai

Patent number: 10186757Abstract: An antenna includes a main body and multiple gain compensation structures. The main body includes a top board and a bottom board, multiple radiation structures are provided on the top board and a feed structure is provided on the bottom board. The multiple gain compensation structures are for partitioning the main body to at least two radiation areas. Each gain compensation structure includes multiple gain compensation units and a shielding structure, and the shielding structure is located between the top board and the bottom board. Each gain compensation unit includes a first coupling structure located on a side that is of the shielding structure and that faces the feed structure. At least a portion of the first coupling structure is located between the top board and the bottom board.Type: GrantFiled: August 15, 2016Date of Patent: January 22, 2019Assignee: Huawei Technologies Co., LtdInventors: Hua Cai, Keli Zou
