  • 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: 20190349050
    Abstract: This application discloses a beam generation method and a base station. In some implementations, planar array antennas are stacked vertically, to form two half planes, and element weighting is independently performed on each half plane. A signal generated by using a baseband may be mapped to an upper-half planar antenna array of a planar array antenna, or mapped to a lower-half planar antenna array of a planar array antenna, or mapped to both an upper-half planar antenna array of a planar array antenna and a lower-half planar antenna array of the planar array antenna, to form a beam.
