Document Type and Number:
Japanese Patent JP4102787
Kind Code:
B2
Abstract:
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.
