The embodiment of the invention provides a shell assembly, an antenna assembly, electronic equipment and a manufacturing method. The shell assembly comprises a metal conducting plate, a substrate anda frame arranged on the outer periphery of the substrate, wherein the metal conducting plate is arranged on the outer surface of the frame; the metal conducting plate comprises a first side face and asecond side face, a plurality of through holes are formed in the opposite directions between the first face and the second side face, and first strengthening structures for strengthening the structural strength are arranged on the peripheries of the through holes and are positioned on at least one side edge of the first side face and the second side face; and/or second strengthening structures for strengthening the structural strength are arranged between every two adjacent through holes. Through the embodiment of the invention, the structural strength at the positions of the through holes ina steel sheet antenna can be improved so as to improve the reliability of the antenna structure in the using process, the antenna structure can be placed preferably on the electronic equipment with limited clearance area, so that the radiation quality of the antenna structure is strengthened.
