Antenna System

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.
