[0053] In the actual manufacturing process, the formation of the coupling adjustment region 600 may include two methods: one is to form a mask layer at the position where the coupling adjustment region 600 is about to be formed during the process of forming the metal layer 500, so as to The metal layer 500 is not formed in this area, so that the coupling adjustment area 600 is formed simultaneously during the formation of the metal layer 500; the other is to form the coupling adjustment area 600 after forming the metal layer 500 that protects the outer surface of all dielectric shells. The position of the adjusting region 600 is etched away by using an etching process, an engraving process or a grinding process to etch away the metal layer 500 in this area, so as to form the coupling adjusting region 600 . The present application does not limit the specific formation process of the coupling adjustment region 600 , which depends on the actual situation.
