Abstract: This application discloses example beam direction adjustment methods, apparatuses, and media. One example method includes obtaining at least one of an azimuth or a pitch angle of a microwave antenna in an antenna system, where the antenna system includes the microwave antenna and a radome installed at an air interface of the microwave antenna, the radome includes a liquid crystal array including M×N liquid crystal cells, and both M and N are integers greater than 0. A target scanning angle of the microwave antenna is determined based on at least one of the azimuth or the pitch angle. A first bias voltage value of the liquid crystal array is determined based on the target scanning angle. A voltage of the liquid crystal array is set to the first bias voltage value.
