Abstract: A method for producing an internal antenna with an anti-electromagnetic interference property by performing a vacuum process, which includes (1) performing a surface pretreatment process on an insulating substrate to clean the surface thereof, (2) placing the substrate into a vacuum chamber, and performing a first plasma bombardment by using a conductive target material; (3) placing the substrate into another vacuum chamber, and performing a second plasma bombardment by using a passivation target material; (4) removing a certain part of the passivation layer and the conductive layer, such that a planar antenna pattern is remained with a certain distance spaced apart from the surrounding passivation layer and conductive layer. The conductive layer and the passivation layer cover the surface of the substrate for completely shielding the electromagnetic interference, and meanwhile, the planar shape of the antenna saves the cost and the available space within the housing.
