Corner-fed type broadband high-isolation dual-polarized antenna

The invention relates to the technical field of microwave antennas, in particular to a corner-fed type broadband high-isolation dual-polarized antenna. The antenna comprises a first dielectric substrate, a second dielectric substrate, a third dielectric substrate, a fourth dielectric substrate and a fifth dielectric substrate, a parasitic patch, a radiation patch, a gap metal plate, two micro-strip feeder lines, a metal reflector plate, two coaxial lines, a first metal isolated via hole and a second metal isolated via hole, wherein the first dielectric substrate, the second dielectric substrate, the third dielectric substrate, the fourth dielectric substrate and the fifth dielectric substrate are laminated from top to bottom in sequence; the parasitic patch is arranged on the lower surface of the first dielectric substrate; the radiation patch is arranged on the upper surface of the third dielectric substrate; the gap metal plate is arranged on the upper surface of the fourth dielectric substrate, and two ort
