Millimeter wave dual-frequency respective feeding dual-polarized antenna array

The invention discloses a millimeter wave dual-frequency respective feeding dual-polarized antenna array, and belongs to the technical field of 5G wireless communication and antennas. The antenna is formed by arranging and combining a plurality of antenna units with the same structure, and each antenna comprises two dielectric layers, three metal layers, two feed probes for low-frequency patch feed, two feed probes for high-frequency patch feed and two coupled feed branches. Wherein the two dielectric layers comprise an upper dielectric substrate A and a lower dielectric substrate B, and the three metal layers comprise a low-frequency annular metal patch, a high-frequency metal patch and a metal floor. According to the invention, two laminated structures of the low-frequency annular metal patch and the high-frequency metal patch are adopted to realize dual-frequency work, feed is carried out respectively at different polarizations and different frequencies, and the burden of a millimeter wave circuit, especia
