ABSTRACT:
A mobile terminal has an electromagnetic interference (EMI) shielding region set at an upper side of a main body part where an internal antenna is mounted. The internal antenna may be mounted on a main printed circuit board (PCB) in order to obtain a desired radiation gain. Such a shielding region alleviates the need to use metallic shielding material or EMI spraying throughout many parts of the terminal. In addition, in order to maximize wireless characteristics of the built-in antenna, a PCB ground is removed from a folder part and a FPCB connector is moved to a position along a side of a terminal display. With this structure, degradation of radiation characteristics of the antenna due to metal components installed around the built-in antenna can be prevented, and thus a stable radiation gain of the terminal antenna can be obtained.
