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.
