Shared-aperture dual-band dual-polarized antenna array and communication equipment

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.
