The other constituent materials of the card base are then sequentially stacked and laminated. And (5) placing the laminated large semi-finished product into a card punching machine, and punching the semi-finished product into a standard double-interface card base. And milling a groove at the position of the double-interface module of the double-interface card base to expose the wire heads at the two ends of the antenna, manually picking the wire heads at the two ends of the antenna from the antenna base material, pulling the antenna out of the antenna base material for a certain length, trimming the pulled two sections of the antenna into the same length and enabling the two sections of the antenna to vertically upwards.
