<p>Disclosed are an antenna device and a manufacturing method thereof. The manufacturing method of the antenna device comprises the following steps: Step One, burying a metal sheet into a plastic body by using insert molding, and making the metal sheet partly exposed to the atmosphere outside the plastic body, for producing a casing member; Step Two, on the plastic body, forming an antenna pattern which can be used to deposit metal; and Step Three, putting the casing member into chemic plating liquid containing metal ions, and making the metal ions reduced and deposited on the antenna pattern so as to form an antenna composed by a metal layer; at the same time, providing a power supply, connecting the positive pole of the power supply to the metal sheet part which is exposed to the atmosphere outside the plastic body and connecting the negative pole of the power supply to an electrode in the chemic plating liquid, and then applying a positive voltage to the metal sheet so as to prevent the metal layer reduced from the metal ions from being deposited on the surface of the metal sheet.</p> |
