Problems solved by technology
[0011] However, methods for reducing electromagnetic wave emission from wireless terminals are limited to attaching electromagnetic wave absorbing material to the antenna or the electric power supply part of the antenna, or moving the electromagnetic wave concentration position, or canceling the electromagnetic wave by changing the ground pattern formed inside the injection-molded component of the terminal.
In addition, although these methods are effective in reducing the absorption rate of electromagnetic waves, they all tend to cause damage to the radiation characteristics of the antenna
These methods also have problems in the position of the electromagnetic wave absorbing material or the grounding pattern should be adjusted by repeated experiments and inspections in order to satisfy the electromagnetic wave absorption ratio of the human body and the radiation characteristics of the antenna

The present invention provides a portable wireless terminal which includes a main body and a folder which is rotatably connected to the main body. The portable wireless terminal further comprises a housing of the main body which is coated with an electrically conductive material on the inner surface in order to provide a ground for an electric circuit device mounted in the main body, a housing of the folder which is coated with an electrically conductive material on the inner surface in order to provide a ground for an electric circuit device mounted in the folder, and a hinge module which is received within the folder and rotatably connects the folder to the main body. The hinge module also electrically interconnecting the ground of the main body and the ground of the folder. The portable wireless terminal of this construction can significantly reduce electromagnetic wave absorption rate by interconnecting the grounds of the main body and the folder thereof through the hinge module.
Description
technical field [0001] The present invention relates to portable wireless terminals, and more particularly, to a folder-type terminal capable of reducing an electromagnetic wave absorption ratio by using a hinge assembly and a method of use thereof. Background technique [0002] In general, portable wireless terminals are classified into bar type, flip type, and folder type according to their appearance. [0003] A strip terminal is a terminal comprising a single body housing housing data input and output devices as well as transmitting and receiving devices. In such terminals, malfunctions may occur due to the fact that the keypad as a data input and output device is always exposed, and there are limitations in miniaturization in order to ensure a sufficient distance between the transmitting and receiving modules . [0004] The flip-type terminal includes a main body, a flip cover and a hinge assembly connecting the main body and the flip cover. The data input and output...
