BUILT-IN ANTENNA MODULE FOR MOBILE DEVICE AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A built-in antenna module for a mobile communication device and a manufacturing method thereof are provided to serve as a matching circuit for impedance matching and to miniaturize the size of the antenna module. CONSTITUTION: A built-in antenna module comprises a non-conductive synthetic resin carrier(110), a radiation pattern(120), a radiating pattern(125), a plating prevention film(130), and a SMD(Surface-Mounted Device)(150). The non-conductive synthetic resin carrier forms a female pattern on the outer surface. The radiation pattern is formed by injecting a plating resin material to the female pattern. The radiation pattern is placed by conductive substrate to form the radiating pattern. The plating prevention film forms non-continuous parts by crossing between lines of the radiation pattern. The SMD is positioned on the plating prevention pattern.
