摘要: This application provides a communication method, apparatus, and system, to receive and send signals simultaneously through different bands, so as to reduce a communication delay. Specifically, a network device sends a first downlink signal to a terminal device through a downlink slot of a first band, and simultaneously, the network device receives a first uplink signal from the terminal device through an uplink slot of a second band, where there is an association relationship between an uplink-downlink slot configuration of the first band and an uplink-downlink slot configuration of the second band. In this application, a plurality of bands may share transmit and receive channel resources of the network device, to reduce costs and power consumption of the network device.

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: Embodiments of this application provide a tightly coupled array antenna and a network device. The tightly coupled array antenna includes: a first dielectric slab. A plurality of antenna units are printed on a lower surface of the first dielectric slab. Each of the antenna units includes a plurality of dipole antennas. The dipole antennas are disposed at intervals. Oscillator arms of the dipole antennas are partially hollowed out. A plurality of coupling structures are printed on an upper surface of the first dielectric slab. Each of the antenna units is electrically connected to one coupling structure. The tightly coupled array antenna provided in embodiments includes at least the first dielectric slab. The plurality of dipole antennas are printed on the lower surface of the first dielectric slab. The oscillator arms of the dipole antennas are partially hollowed out. The oscillator arms of the dipole antennas are designed to be partially hollowed out, so that a capacitance formed between the oscillator arms and the first dielectric slab is reduced, and a cross-sectional area of a current path is also reduced to increase an impedance real part, thereby achieving an objective of reducing an active standing wave of the tightly coupled array antenna.
