摘要： Antenna elements (101, 102) used for multi-band antenna dual polarization include: four radiating elements (201), a balun element configured to feed power to the radiating elements (201), and a fastening plate (202) configured to fasten the balun element. The balun element includes two dielectric plates (203). Two signal transmission units (301), one feeding unit (401), and two filtering units (402) are printed on each dielectric plate (203). An LC resonant energy storage structure is constructed on the balun element by using the filtering units (402), and decoupling on a specific frequency band can be implemented by adjusting the filtering unit (402). Therefore, even if the antenna elements (101, 102) are applied to a scenario in which elements on different frequency bands work collaboratively, radiating elements (201) on different frequency bands are not coupled electromagnetically and strongly when the radiating elements are arranged closely, so that the antenna elements (101, 102) can ensure normal working of an antenna on a related frequency band.

摘要： This application provides a data processing method and a communication apparatus, and relates to the field of communication technologies. The method can be used for downlink data processing and uplink data processing. The communication apparatus may receive a reference signal, and obtain a first matrix based on the reference signal. The first matrix is an autocorrelation matrix whose dimension is N rows and N columns, and N indicates a quantity of channels of an antenna array. Based on the first matrix, channels in different rows of the antenna array are averaged to obtain a second matrix, where a dimension of the second matrix is N/(x×R) rows and N/(x×R) columns; R represents a quantity of channel rows of the antenna array; x represents polarization of the antenna array. When the antenna array is a single-polarized antenna array, x is 1. When the antenna array is a dual-polarized antenna array, x is 2. In this application, a dimension of the first matrix is reduced, to improve data processing efficiency. In addition, the channels in the different rows of the antenna array are averaged. In this way, impact of related interference between channel rows of the antenna array can be reduced.
