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.
