Of course, the shape of the antenna circuit 603 is not limited to the pattern in the drawing; the front circuit and the back circuit can be engraved through a process Kong Lei, and then copper plating is performed for physical conduction; thereafter, the surface case 602 is subjected to surface treatment such as oil injection, and the antenna circuit 603 is protected.
