Abstract: The invention discloses shared-aperture dual-band dual-polarized antenna array and communication equipment. The antenna array comprises a first dielectric substrate, a second dielectric substrate, a third dielectric substrate, a fourth dielectric substrate, and a fifth dielectric substrate. The first dielectric substrate, the second dielectric substrate, and the third dielectric substrate constitute a dielectric substrate group. The dielectric substrate group is provided with a low-frequency antenna element and four high-frequency antenna elements. The low-frequency antenna element is loaded with a filtering structure. The low-frequency antenna element and the high-frequency antenna element are fed by coaxial lines. The fourth dielectric substrate and the fifth dielectric substrate form a dual-function metasurface. When the dual-function metasurface is used as an artificial magnetic conductor reflector, the radiation of the low-frequency antenna element is enhanced in a low profile, and when used as a frequency selective surface, the electromagnetic scattering of the low-frequency antenna element in the high-frequency band is suppressed. Compared with the existing solutions, the present invention is more compact, and maintains high cross-band isolation and stable radiation patterns in dual bands.
