摘要: This application provides a radiating element, an antenna array, and a network device, to avoid mutual shielding between dipoles during multi-band transmission, and therefore improve radiation performance. The radiating element includes one or more dipoles and a supporter. The one or more dipoles are suspended on the top of the supporter, and each of the one or more dipoles is connected to the supporter at a specific angle. A dipole arm of each dipole is covered with a periodic structure. The periodic structure is configured to enable an electromagnetic wave radiated to a first surface of each dipole to be incident to a second surface of each dipole, where the first surface and the second surface are any two opposite surfaces of each dipole.

摘要: This application provides an antenna system and a signal transmission method. The antenna system includes: a transmit end antenna array and a transmit end matching network, where an S parameter matrix of the transmit end matching network matches an S parameter matrix of the transmit end antenna array and is configured to perform pre-distortion on a to-be-transmitted signal, and the transmit end antenna array is configured to transmit the to-be-transmitted signal that has been pre-distorted by the transmit end matching network. According to the antenna system and the signal transmission method provided in this application, by using the matching network, pre-distortion may be performed on a signal that needs to be transmitted by the antenna array or de-distortion may be performed on a signal received by the antenna array, so as to configure energy that is coupled from each antenna array element to an adjacent antenna array element, thereby reducing a coupling effect between antenna array elements.

摘要: This application provides a beamforming network architecture of an N-drive-M network, and relates to the field of communication antenna technologies. The architecture includes: A first circuit includes at least one bridge, where input ends of the at least one bridge are coupled to digital channels in N analog networks, to perform digital weighting and analog on a received electrical signal; a second circuit includes at least one bridge, where output ends of the at least one bridge are coupled to M antennas, to perform digital weighting and analog on a received electrical signal; and a connection circuit includes at least one power splitter, where an input end of the at least one power splitter is coupled to an output end of the at least one bridge in the first circuit, and an output end of the at least one power splitter is coupled to an input end of the at least one bridge in the second circuit, to divide a quantity of electrical signals from N to M through power splitting. The beamforming network architecture designed in this application can implement a plurality of wide beams or a plurality of narrow beams by connecting a plurality of levels of components. In addition, a plurality of wide beam ports are highly isolated. Narrow beam sweeping in a coverage area can also be implemented through the network.
