  • Patent number: 11005546
    Abstract: An antenna system is disclosed. The system includes: N radio frequency channels, configured to send a radio frequency signal to drive one or two columns of M columns of antennas, and N<M?2N; the M columns of antennas, configured to receive radio frequency signals, where only one column of two columns of antennas driven on a same radio frequency channel are connected to one of the M?N phase shifters, and is also connected to one of the M?N power splitters; the M?N power splitters, where any of the M?N power splitters is configured to split power for the two columns of antennas connected to the radio frequency channel; and the M?N phase shifters, where any of the M?N phase shifters is configured to adjust a phase of a radio frequency signal received by an antenna connected to the phase shifter.

  • Patent number: 10879610
    Abstract: 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.

  • Publication number: 20200303832
    Abstract: 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.

  • Patent number: 10333220
    Abstract: Embodiments of the present invention disclose an interleaved polarized multi-beam antenna, including: at least one dual-polarized antenna element, where the dual-polarized antenna element includes a +45-degree-polarized first antenna element and a ?45-degree-polarized second antenna element; and a first Butler matrix and a second Butler matrix, where the first Butler matrix is connected to the first antenna element so that the first antenna element transmits a first target beam, and the second Butler matrix is connected to the second antenna element so that the second antenna element transmits a second target beam. The first target beam and the second target beam in the embodiments are alternately arranged, and any two adjacent first target beam and second target beam have different polarization characteristics; therefore, complexity, a loss, and costs of implementation of a Butler matrix can be effectively reduced, and interference between adjacent multiplexed beams can be effectively decreased.
