Abstract: Embodiments of the present disclosure provide example antennas, example microwave devices, and example communications systems. One example antenna includes an antenna body and a filter component. The antenna body includes an antenna aperture and an optical axis. The antenna body is configured to send and receive a radio frequency signal that passes through the antenna aperture. The filter component is located at the antenna aperture and is disposed perpendicular to the optical axis, where the filter component is configured to filter an interference signal in the radio frequency signal. The filter component includes a filter layer and a support component, where the filter layer is formed by a lossy dielectric, where the support component is configured to support the filter layer, and where the filter layer forms a spatial structure similar to a shutter.

Abstract: Embodiments of this application disclose a user pairing method and a related device. The method includes: first, determining a first generation parameter of a first base sequence of a first user and a second generation parameter of a second base sequence of a second user, and the second base sequence is used to generate a second uplink reference signal of the second user; then, determining multiplexing evaluation information based on the first generation parameter and the second generation parameter, where the multiplexing evaluation information may include correlation strength between sequences and interference leakage width; afterwards, determining, based on the multiplexing evaluation information, whether the first user and the second user are successfully paired. Finally, when the first user and the second user are successfully paired, it is determined that the first user and the second user multiplex a same communication resource for communication.

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.
