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.

Abstract: A beam configuration method and a device are provided and can resolve problems that a signal gain is a relatively low and utilization of an antenna array unit is low in a process of implementing omnidirectional coverage of a millimeter wave. A specific solution is as follows: determining whether an included angle between a ray that is perpendicular to a first plane and that extends outward from an electronic device and a ray pointing from the electronic device to a peer device is less than or equal to a preset angle, and when the included angle between the ray that is perpendicular to the first plane and that extends outward from the electronic device and the ray pointing from the electronic device to the peer device is less than or equal to the preset angle, performing end-fire state configuration on antenna array units in the first plane.
