description The invention provides a patch-loaded broadband dual-polarized base station antenna. The patch-loaded broadband dual-polarized base station antenna comprises a first broadband balun structure, a second broadband balun structure, a metal patch and a reflecting plate. The first broadband balun structure and the second broadband balun structure are connected with the reflecting plate; the first broadband balun structure and the second broadband balun structure are perpendicular to the reflecting plate and are orthogonal to each other; and the metal patch is arranged above the first broadband balun structure and the second broadband balun structure. According to the invention, a novel resonance mode can be introduced through balun structure coupling excitation, so that the bandwidth of the antenna is expanded; the feed structure and the radiation unit are integrally designed, and the antenna bandwidth is expanded by loading patches, so that the design of the antenna can be simplified; while a wide working band is
