Patent number: 7668575Abstract: 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.Type: GrantFiled: July 28, 2004Date of Patent: February 23, 2010Assignee: LG Electronics Inc.Inventors: Byung-Duck Park, Soo-Cheoul Kim

Patent number: 7541986Abstract: A mobile terminal includes a terminal case, a main PCB inside the terminal case mounting various circuit components thereon, and an internal antenna fixed on the main PCB. The internal antenna can transmit and receive radio waves bearing voice and image information to and from the main PCB and shield electromagnetic wave generating parts mounted on the main PCB. Thus, embodiments of an internal antenna, a mobile terminal and methods thereof can reduce size and costs, and can shield RF elements or the like discharging a large amount of electromagnetic waves or circuit components among parts installed on the main PCB so that leakage of electromagnetic waves can be reliably reduced or prevented.Type: GrantFiled: July 22, 2004Date of Patent: June 2, 2009Assignee: LG Electronics Inc.Inventor: Byung Duck Park
