The utility model relates to a wideband low-profile cavity backed integrated antenna. The existing product has large volume and high processing cost. The wideband low-profile cavity backed integrated antenna comprises a media substrate, an annular metal strip coated on the upper surface of the media substrate, a metal ground layer completely coated on the media substrate, an electrical interconnection array formed of a plurality of electrical interconnection units by sequential arrangement, a feeding unit and a radiation unit. The metal strip, the metal ground layer and the electrical interconnection array form a cavity structure by surrounding. The duty ratio between any two adjacent electrical interconnection units of the electrical interconnection array is larger than 1. The electrical interconnection unit is a metal through hole or a metal post passing through the metal strip, the media substrate and the metal ground layer. The wideband low-profile cavity backed integrated antenna provided by the utility
