摘要： This application discloses a beam direction adjustment method, which is applied to an antenna system including a microwave antenna and a radome, where the radome includes a liquid crystal array including M×N liquid crystal cells, and the method includes: obtaining an azimuth and/or a pitch angle of the microwave antenna; determining a target scanning angle of the microwave antenna based on the azimuth and/or the pitch angle; determining a first bias voltage value of the liquid crystal array based on the target scanning angle; and setting a voltage of the liquid crystal array to the first bias voltage value. Embodiments of this application further provide a corresponding apparatus. In the technical solutions of this application, when it is detected that the microwave antenna deviates to an angle, a transmission phase of a liquid crystal cell may be changed by adjusting a liquid crystal bias voltage of the liquid crystal array in the radome, to implement a corresponding phase layout, so that a beam of the microwave antenna scans the angle. In this way, automatic tracking and alignment are implemented.

摘要： A beam configuration method and a device relate to the field of communications technologies, and can resolve problems in the prior art 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 by using a broadside antenna and an end-fire antenna. 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 (101), 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 (102).

摘要： Embodiments of this application disclose an antenna apparatus, applied to the communications field. Embodiments of this application include: A feed converts a guided electromagnetic wave into a beam, and then sends the beam to a defocusing apparatus. Then, the defocusing apparatus may change a transmission direction of the beam. In this way, the defocusing apparatus sends the beam whose transmission direction is changed to a beam shaping panel, and the beam shaping panel changes the transmission direction of the beam and a transmission shape of the beam, and then transmits the beam to a peer antenna, to implement information transmission. The defocusing apparatus changes the transmission direction of the beam, so that a spatial distance between feeds may be increased, feed arrangement density may be reduced, and a case in which physical positions of the feeds overlap may be avoided, to properly arrange the feeds and ensure a communication effect.
