Fig. 2 reduces the structural representation of the pcb board (inhaling the ripple paster sticks on the radome) of the mobile phone of radiation dispersion for the utility model.
Embodiment
The utility model provides a kind of mobile phone that reduces radiation dispersion, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Through the radiation dispersion test, confirm the frequency range (point) that mobile phone radiation disturbs, the radiated interference of mobile phone mainly is secondary, the triple-frequency harmonics of main ripple.The radiation dispersion of mobile phone mainly is to be produced by antenna, and mainboard self radiation can be ignored.In the utility model; The band that reduces mobile phone through employing suction ripple paster is outer spuious; Inhale in the ripple patch location process in adjustment constantly; Inhale the ripple patch location and choose in the radiation cavity that main direction is an antenna or peripheral components and parts, come final fixed position of confirming to inhale the ripple paster through the spuious variation of reality test.
In the lump with reference to figure 1 and Fig. 2; The mobile phone of the reduction radiation dispersion that the utility model provides; Comprise pcb board 100, antenna 110, inhale ripple paster 120, antenna periphery components and parts 130 and radome 140, said antenna 110, antenna periphery components and parts 130 and radome 140 are welded on the pcb board 100.As shown in Figure 1, as one of preferred version, said suction ripple paster 120 is arranged between antenna 110 and the antenna periphery components and parts 130, and antenna 110 and antenna periphery components and parts 130 are isolated.As shown in Figure 2, as two of preferred version, said suction ripple paster 120 also can be arranged on the top of radome 140.
Said suction ripple paster 120 comprises substrate and inhales ripple particulate layer that said suction ripple particulate layer sticks on the substrate through binding agent, forms described suction ripple paster through compression forming.Said suction ripple particulate layer can be metal powder layer, metallic fibrous layer, layer of metal foil or polycrystalline ferrite layer.Said binding agent can be sheet, spherical or shaft-like.Absorb and reflex because said suction ripple particulate has microwave, the utility model promptly is to utilize the microwave absorbing property of inhaling the ripple paster to optimize the radiation dispersion of mobile phone.
In the utility model scheme, said suction ripple paster preferably is substrate with the spirulina, inhales ripple particulate layer at the surface deposition of spirulina substrate, and said suction ripple particulate layer adheres on the said spirulina substrate through bonding agent, is bionical suction ripple paster through compression forming.This bionical suction ripple paster has characteristics with low cost, excellent performance with respect to other general suction ripple pasters.
The utility model reduces in the mobile phone of radiation dispersion, and the thickness of said suction ripple paster 120 generally is controlled in the 1mm, and this has just limited the bandwidth of inhaling ripple paster 120 can not be the broadband, selects to inhale accordingly the ripple paster according to the frequency range of disturbing.Such as, if the frequency of electromagnetic radiation of antenna mainly concentrates on below the 1GHz on the pcb board, the suction ripple paster that adapts to the 1GHz frequency range is set between antenna 110 and peripheral components and parts 130 then; The frequency of electromagnetic radiation of radome 140 concentrates on more than the 2GHz, then adopts the suction ripple paster that adapts to the 2GHz frequency range.
With having adopted the utility model mobile phone of inhaling the ripple paster and the mobile phone that does not adopt paster to carry out the radiation dispersion contrast, the contrast of its EMC (Electro Magnetic Compatibility) data is as shown in table 1 below, and the EMC of the utility model mobile phone obviously improves, and effect is quite obvious.(V is the vertical abbreviation; H is the horizontal abbreviation; The V of V-H is the placing direction of mobile phone on testboard; H is the direction of spuious reception antenna)
Table 1 has the EMC test result of paster mobile phone and no paster mobile phone
| Antenna direction | There is not the ripple paster (dBm) of suction | The ripple paster (dBm) of suction is arranged | EMC improves (dBm) |
| V-H | -42.7 | -48.54 | 5.84 |
| H-V | -35.75 | -45.99 | 10.24 |
| V-V | -36.27 | -44.52 | 8.25 |
| H-H | -42.53 | -41.97 | -0.56 |
Therefore, the above-mentioned bionical suction ripple paster of antenna periphery increase at mobile phone can reduce the radiation dispersion of mobile phone, thereby reduces mobile phone to the outer spuious interference to other high frequency spectrums of the band of human body radiation, mobile phone.Because said suction ripple paster has the effect of absorption and microwave reflection, therefore can also improve the mobile phone electromagnetic interference capability of environment existence to external world.Said suction ripple paster can not only be used to reduce the radiation dispersion of mobile phone, can also be used for other electronic products such as panel computer.
Should be understood that; The application of the utility model is not limited to above-mentioned giving an example; Concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, all these improvement and conversion all should belong to the protection range of the utility model accompanying claims.
