摘要： An antenna system applicable to a mobile communication device is provided in the present disclosure. The antenna system includes a metal shell with a metal frame and a metal back cover, a printed circuit board (PCB) housed in the metal shell, and an antenna part with a first feed point and a second feed point. A first break point and a second break point are formed at two opposite sides of the metal frame; a first gap and a second gap are respectively formed at two opposite sides of the metal back cover for defining a first clearance area and a second clearance area. The first feed point is located in the first clearance area and contacts a left frame portion of the metal frame; the second feed point is located in the second clearance area and contacts a right frame portion of the metal frame.

摘要： An additive manufacturing process for forming a metallic layer on the surface of the substrate includes fabricating a substrate from a polymerizable composition by a stereolithographic process, and contacting the reactive surface with an aqueous solution including a metal precursor. The metal precursor includes a metal, and the polymerizable composition includes a multiplicity of multifunctional components. Each multifunctional component includes a reactive moiety extending from a surface of the substrate to form a reactive surface. An interface between the reactive surface and the aqueous solution is irradiated to form nanoparticles including the metal. The nanoparticles are chemically coupled to the reactive surface by reactive moieties, thereby forming a metallic layer on the surface of the substrate.
