ABSTRACT:
BACKGROUND OF THE INVENTION
In current communication world, those controlling the communication technology will become a winner of current information world. Thus, communication devices have become necessary equipment. Since mobile phones are more and more popular, almost everybody has one. However, with the increment of communication traffic, electromagnetic radiation is also filled in the air. But this is harmful to the human body. Especially, the electromagnetic radiation from the mobile phone of user himself (herself) because the radiation from user's mobile phone is very near the body of user, especially the brain.
The current mobile phone system has been advanced to digital mobile phones from early analog mobile phones, the frequency band ranges from 800 MHz to 1000 MHz, recently, 1800 MHz frequency is also included. Such high frequency electromagnetic radiation has a great transmission property. When the mobile phone with a power of 0.5 watt is emitted, it the mobile phone is near the neck portion of user, about 0.2 watt of power will penetrate through the head of the user and is probably produced a bad effect.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an electromagnetic radiation protection device of a mobile phone installed at one side of an antenna of a mobile phone, thereby 80% of electromagnetic radiation is absorbed, therefore the sub-effect of the mobile phone is reduced greatly.
Another object of the present invention is to provide an electromagnetic radiation protection device of a mobile phone installed at one side of an antenna of a mobile phone. The device comprises an electromagnetic wave absorbing piece, a dielectric plate, an electronic joint loop, a negative electrode lead, etc. The electromagnetic wave absorbing piece serves to absorb the electromagnetic wave toward the user's head. Then the electromagnetic wave irradiates to the negative electrode lead of a power source through the electronic joint loop and the negative electrode lead.
A further object of the present invention is to provide an electromagnetic radiation protection device of a mobile phone, which may be assembled and used easily and is effective for isolating the electromagnetic radiation of a mobile phone. The device is formed simply by a plurality of metal pieces, plastic piece, and electronic circuit.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
