Abstract
The utility model discloses a reflector for reducing antenna radiation of mobile phones. In the utility model, the outer side of a mobile phone machine body is provided with a metal sheet which is connected with a grounding line of a PCB plate of the mobile phone. The utility model can change field types with maximum extent and can optimize speech quality.
Description
Technical field
The utility model relates to antenna for mobile phone, particularly relates to a kind of reflector that reduces handset antenna radiation.
Background technology
Along with the popularity rate of mobile phone is more and more higher, the user is also more and more.Though it is very convenient to use mobile phone to carry out communication, whether people also worry mobile phone radiation unavoidably and can impair one's health, when particularly conversing from the health of the nearest brain of mobile phone.And having one to be SAR (specific absorption rate absorption rate) in the performance index of antenna for mobile phone, SAR is exactly to the size of human brain amount of radiation in the testing mobile phone communication process.CTA (Chinese network access testing) authentication that present Chinese mobile phone networks has added the SAR test.SAR is relevant with gain and field pattern in mobile phone maximum transmission power and the antenna performance.Maximum transmission power is to satisfy 3GPP (The 3rd GenerationPartnership Project) code requirement, so the maximum transmission power of all mobile phones almost is the same.Therefore gain is the key of mobile phone radiation amount size with field pattern.If the ratio of gains of antenna is less, SAR can improve, but the reception of mobile phone and emissivities are with regard to variation concerning mobile phone, can't eat one's cake and have it.Also having a kind of method is exactly to adjust the field pattern of antenna, makes the one side gain towards human body reduce the then increasing of human body dorsad.Yet the antenna patterns illustrated of same type almost is the same, and the space of adjustment is very little.
The utility model content
The technical problems to be solved in the utility model provides a kind of reflector that reduces handset antenna radiation, and it can farthest change field pattern, and optimizes speech quality.
For solving the problems of the technologies described above, the utility model reduces the reflector of handset antenna radiation, is provided with a sheet metal outside the mobile phone body, and this sheet metal is connected with the ground wire of the pcb board (printed-circuitboard printed circuit board) of mobile phone.
Owing to adopt said structure, when using mobile phone to converse, the reflector retaining that the utility model can be reduced handset antenna radiation is on the brain limit, to change the field pattern of antenna, the signal that is radiated brain is significantly reduced, and increased the signal of brain direction dorsad, can guarantee the speech quality of mobile phone.The utility model has following advantage specifically: 1, the utility model does not reduce the radiation field energy, but with concentration of energy to away from a side of brain.2, the radiation field of original mobile phone must be absorbed by brain by some energy, has reduced the loss of this part energy now, can make the signal of mobile phone better.3, the utility model manufacture craft is simple, cost is low, and effect is obvious, and it is big that the choice becomes.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Fig. 1 is the radiation field of aerial schematic diagram before inserting reflector on the mobile phone;
Fig. 2 is that structure of the present utility model reaches the radiation field of aerial schematic diagram after the access reflector on mobile phone;
Fig. 3 is another example structure schematic diagram of the utility model.
Embodiment
As shown in Figure 2, the utility model reduces the reflector of handset antenna radiation, is provided with a sheet metal 1 outside mobile phone 2 bodies, and this sheet metal 1 is connected with the ground wire of the pcb board of mobile phone 2.During conversation sheet metal 1 is kept off on the brain limit,, the signal that is radiated brain is significantly reduced, and increase the signal of brain direction dorsad, guarantee the speech quality of mobile phone to change the field pattern of antenna.The mode that the reflector of the utility model minimizing handset antenna radiation links to each other with mobile phone 2 can adopt multiple version.For example, sheet metal 1 is made into the ear muff style, re-uses the metal hasp 4 on the metal bracelet 3, be arranged on mobile phone 2 on metal suspension ring 5 snap close mutually, and then realization is connected with the ground wire of the pcb board of mobile phone 2.The sheet metal 1 of ear muff formula can be enclosed within on the ear during use, voice signal can propagate into people's ear by the voice guide hole on the sheet metal 16.
As shown in Figure 3, also can adopt the travel(l)ing rest mode that metallic plate 7 is arranged on the mobile phone.Described travel(l)ing rest comprises a metallic support bar 8, and metallic plate 7 is arranged on an end of metallic support bar 8, the other end of metallic support bar 8 be fixed on mobile phone on and the metal shaft that is connected with the ground wire of pcb board 9 flexibly connect.Metallic plate 7 can turn down up and down on travel(l)ing rest, metallic plate 7 can be folded in one's ear during conversation.So the utility model is made very big flexible property, can not touch antenna but must guard against in the communication process, maintain a certain distance.
Fig. 1 is the radiation field of aerial schematic diagram that does not insert reflector of the present utility model on mobile phone, by shown in the figure as can be known, the signal that is radiated brain is very big.
Claims (6)
1, a kind of reflector that reduces handset antenna radiation is characterized in that: be provided with a sheet metal outside the mobile phone body, this sheet metal is connected with the ground wire of the pcb board of mobile phone.
2, according to the reflector of claims 1 described minimizing handset antenna radiation, it is characterized in that: described sheet metal is the ear muff type, is connected by the ground wire of metal bracelet with the pcb board of mobile phone.
3, according to the reflector of claims 2 described minimizing handset antenna radiations, it is characterized in that: an end of described metal bracelet is provided with the metal hasp, this metal hasp be arranged on mobile phone on and the metal suspension ring that are connected with the ground wire of pcb board snap close mutually.
4, according to the reflector of claims 1 described minimizing handset antenna radiation, it is characterized in that: described sheet metal is arranged on the mobile phone by travel(l)ing rest.
5, according to the reflector of claims 4 described minimizing handset antenna radiations, it is characterized in that: described travel(l)ing rest comprises a metallic support bar, sheet metal is arranged on an end of metallic support bar, the other end of metallic support bar be fixed on mobile phone on and the metal shaft that is connected with the ground wire of pcb board flexibly connect.
6, according to the reflector of claims 4 or 5 described minimizing handset antenna radiations, it is characterized in that: described sheet metal can turn down up and down on travel(l)ing rest.
