Technical Field

The invention belongs to the technical field of communication, and particularly relates to an integrated structure of an antenna and a communication equipment shell and a preparation method thereof.

Background

Nowadays, with the rapid development of smart phones, people put higher demands on the structural design and manufacture of cell phone antennas and communication equipment shells.

For example, the material of the mobile phone case has been replaced with a material such as metal, glass, or ceramic from a conventional non-conductive plastic. And when adopting the metal material of electric conductivity to do the cell-phone shell, because the shielding effect of the electric conductivity of metal to cell-phone antenna radiator, the design of cell-phone antenna has to be made necessary adjustment, common scheme is to the cell-phone shell of metal material cut open the window and cut apart to reserve the region that supplies the antenna radiation, but the shortcoming of this kind of scheme is also obvious, for example destroyed the pleasing to the eye effect of cell-phone shell integration, increased the assembly degree of difficulty etc. to the shortcoming of this kind of scheme, have a large amount of improvement schemes to be proposed, no longer describe herein repeatedly.

For another example, as more and more electronic modules need to be integrated inside a smart phone, the space inside the smart phone will be more and more crowded, which puts higher demands on the reasonable layout of each electronic module. One proposal currently proposed by manufacturers, represented by apple inc, is to save the internal space of a mobile phone by using metal as a part of the mobile phone case and using the part of the metal mobile phone case as an antenna radiator. This concept is effective, but there are some problems to be improved. Specifically, the metal portion of the handset housing and the other non-conductive portions of the handset housing (which are currently generally made of plastic, and particularly the connector portions are also made of plastic) are formed separately and then assembled together to form a complete handset housing. The scheme has the defects that the design method does not substantially help to improve the aesthetic effect of the integrated design of the mobile phone shell, people can still observe a large number of assembly joints from the appearance, and the assembly joints are weak links of the waterproof and dustproof functions of the mobile phone, so that the waterproof and dustproof levels of the mobile phone are greatly damaged. The highest level of the dustproof and waterproof performance of the current mobile phone is IP68, the protection level specifies the immersion of the mobile phone when the mobile phone is submerged, specifically, the mobile phone is continuously immersed for 30 minutes below 1.5 meters away from the water surface, and the performance is not affected and does not leak water. However, in the practical use of the current user, people find that the mobile phone does not have the effective dustproof and waterproof effect in many application scenes, and if the air leakage prevention function can be added on the basis of the dustproof and waterproof function of the mobile phone, the protection level of the mobile phone is greatly improved.

In addition, the plastic parts that cannot be completely replaced are contrary to the trend of material selection of the current mobile phone shells, and the flexibility of design and manufacture of the mobile phone shells is also limited.
