Patent attributes
The present application relates to the field of antenna technologies, and discloses a shared-aperture antenna and a base station, to resolve a problem of sharing an aperture between antenna arrays working in different frequency bands. The shared-aperture antenna includes a dielectric substrate, a microstrip antenna array, and an electrically small antenna array, where the microstrip antenna array includes rows of microstrip patch antenna units uniformly distributed in arrays, and the microstrip patch antenna units fit a surface of the dielectric substrate; the electrically small antenna array includes electrically small antenna units that are parallel to each other; and the electrically small antenna units are inserted at intervals between the microstrip patch antenna units, and fit the surface of the dielectric substrate.
