Abstract: A tightly coupled array antenna and a network device are provided. The tightly coupled array antenna includes a first dielectric slab and a plurality of antenna units printed on a lower surface of the first dielectric slab. Each of the antenna units includes a plurality of dipole antennas that are disposed at intervals. Oscillator arms of the dipole antennas are partially hollowed out to reduce both capacitance formed between the oscillator arms and the first dielectric slab and the cross-sectional area of a current path. A plurality of coupling structures is provided on an upper surface of the first dielectric slab so that each of the antenna units is electrically connected to one coupling structure.

Abstract: An antenna system, a feeding network reconfiguration method, and an apparatus is disclosed. The antenna system may include an antenna array, a reconfigurable network unit, a control unit, and K radio frequency channels. The antenna array may include L antenna subarrays, and the reconfigurable network unit may divide the L antenna subarrays into M antenna subarray groups, and separately connect the M antenna subarray groups to the K radio frequency channels; any one of the K radio frequency channels may perform signal processing on a signal received by a connected antenna subarray group and/or a to-be-transmitted signal; and the control unit may control the reconfigurable network unit to adjust a mapping relationship between an antenna subarray group connected to each radio frequency channel and the antenna subarrays.

Abstract: 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.
