Broadband low-profile dual-polarization Vivaldi antenna unit with novel feed structure

The invention discloses a broadband low-profile dual-polarization Vivaldi antenna unit with a novel feed structure, the broadband low-profile dual-polarization Vivaldi antenna unit comprises a metal floor, a dielectric feed layer, a metal antenna unit and two radio frequency connectors, the metal antenna unit comprises two single-polarization units which are perpendicular to each other, the two single-polarization units are connected with each other, the joint shares a metal column, and the metal column is connected with the dielectric feed layer. The two single-polarization units are identical in structure, the dielectric feed layer is arranged between the metal floor and the metal antenna unit, the two radio-frequency connectors are arranged in the metal floor, and probes of the two radio-frequency connectors respectively feed the two single-polarization units after penetrating through the dielectric feed layer. The feed structure is easy to weld, stable connection between the radio frequency connector and
