Embodiments of the present application provide a housing 
assembly, an antenna 
assembly, and an electronic device.  Wherein the antenna 
assembly includes a first substrate, a second substrate and an antenna structure, the second substrate is fixedly connected to the first substrate, the second substrate is made of non-metallic material, the second substrate includes a frame, and the frame  Around the periphery of the first substrate, the outer surface of the frame has a first 
rough surface; the antenna structure has a second 
rough surface, and the antenna structure is arranged on the outer surface of the frame, the first 
rough surface and the second rough surface  
Rough surface connection, the antenna structure includes a feeding point and a grounding point, the feeding point extends from the frame position toward the inside of the second substrate, and the grounding point extends from the frame position toward the second substrate  The inner direction of the substrate extends, and the ground point is connected to the first substrate.  The embodiment of the present application can increase the clearance area of the antenna structure in the electronic device, and improve the 
radiation signal strength of the antenna structure.
