Abstract
The utility model provides an environmental protection type mobile phone for communication. A plane aerial with a reflecting plate at the rear side of the mobile phone for communication (which is arranged at the opposite side of a shell and approaches to human face) can reduce electromagnetic energy radiated by an aerial which enters into human head, and achieve the function of brain and eye protection. The utility model is suitable for all mobile phones for communication.
Description
The utility model relates to a kind of antenna for mobile phone, and it is applicable to all mobile communication mobile phones.
The mobile communication mobile phone antenna overwhelming majority of modern popular is the omnidirectional antenna that exposes, be close to ear, close eyes in the use, antenna is absorbed by the head part the radiation major part of human body head direction, and its intensity is often greatly to being the degree that is enough to constitute to the human injury.The news briefing that on January 30th, 1997, German Hagennk company came Guangzhou to hold, announce its built-in antenna, can play and reduce the effect of electromagnetic radiation the brain influence, what it was taked is the dielectric resonant chamber slot antenna, antenna thickness is thicker, and therefore its lotus root zoarium exists the side direction radiation in the resonant cavity side, is difficult to reduce the possibility to the radiation intensity of eyes.
Recently the someone propagates at the existing mobile phone back side with exposed omnidirectional antenna and sticks a slice magnetic antenna again, can reduce electromagnetic radiation to the influence of brain with increase that to receive field boundary strong.Because to paste be passive antenna in institute, the used exposed antenna emission effect of former machine is constant, in fact is difficult to obtain the effect of protecting brain and eyes.
By test, at present the antenna for mobile phone of tracking exchage often reaches tens volts every meter even above 100v/m, considerably beyond the regulation of national safety standard 28v/m to brain and eyes position radiation intensity.
Adopt the purpose of this utility model to be to avoid weak point of the prior art and a kind of environment-friendly type mobile communication mobile phone antenna is provided, be (promptly with the relative one side of casing face of pressing close to end user's face) places the band reflecting plate at the mobile communication apparatus back side planar antenna reducing the injury of electric wave, and be applicable to various mobile communication mobile phones brain and eyes.After adopting the utility model, under the prerequisite that does not influence normal communication, reduce electromagnetic wave brain and eyes radiant power are reached 100 times.
Fig. 1 is the cutaway view of a kind of concrete structure of the utility model.
The purpose of this utility model can be by use establishing with the flat plane antenna of reflecting surface Meter reaches, and this design is thinner than existing dielectric resonant chamber slot antenna. It is concrete The realization accompanying drawings is as follows: the illustrated structure bottom 1 is metallic reflector, This face is pressed close to human body head; Intermediate layer 2 is dielectric layer, and outer surface 3 is radiating element, This face is radiating surface, radiating element to the radiation of human body head direction by bottom metal layer Reflection, and strengthened radiation intensity round about, it is single that dielectric layer plays the supporting radiation The effect of unit and minimizing antenna size, radiating element then is the radiant body of antenna.
Radiating element is a plane, also can be square, fan-shaped, Double-spiral or other planar structures.
The utility model compared with prior art has following advantage:
1. accomplish to reduce the injury of mobile communication mobile phone electromagnetic radiation really to human brain and eyes;
2. the planar dimension that may provide according to mobile phone is selected suitable medium, to shorten wavelength, makes the antenna mobile phone of can packing into;
3. comparing with the dielectric resonant chamber slot antenna makes the thickness of antenna thinner.
In sum, the utility model is under the prerequisite that does not influence proper communication, and the electromagnetic energy that significantly reduces aerial radiation enters human body head, plays the effect of protection brain and eyes.
Claims (2)
1. an environment-friendly type antenna for mobile phone that is used for mobile communication is characterized in that the antenna bottom described in the utility model (1) is a metallic reflector, and intermediate layer (2) are dielectric layer, and outer surface (3) is a radiating element.
2. the described antenna of root a tree name claim 1, its radiating element is a plane, also can be square, fan-shaped, Double-spiral or other planar structures.
