Problems solved by technology

[0004] refer to figure 2 , because the upper casing 91 and the lower casing 92 of the portable communication device 9 are designed with metal materials, but once the upper casing 91 and the lower casing 92 are closed, the two-layer metal structure will cause current coupling, so that the antenna The communication effect of 93 is affected to a certain extent, for example: the two metal layers very close (0.15mm) are similar to the capacitor structure, which will couple unnecessary current and cause the gain attenuation of antenna 93

Embodiment Construction

[0040] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of several preferred embodiments with reference to the accompanying drawings. Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0041] refer to image 3 and Figure 4 , in a preferred embodiment of the present invention, the communication device 100 is a foldable electronic product, such as a mobile phone or a notebook computer, comprising an antenna 3 with a communication function, a first housing 1 and a second housing 2. The first shell 1 and the second shell 2 are opened (such as image 3 ), and the closed state (such as Figure 4 ), the first casing 1 and the second casing 2 are adjacent to the antenna 3 .

[0042] refer to Figure 4 , the first shell 1 includes a first metal layer 11 a...

Abstract

The invention discloses a communication device of reducing double-layer metal coupling current. The communication device comprises an antenna, a first shell and a second shell. The first shell comprises a first metal layer and a first non-metal layer; the first metal layer comprises a plurality of first gaps which are concavely arranged; the first non-metal layer is filled into the first gaps; the second shell comprises a second metal layer and a second non-metal layer; the second metal layer comprises a plurality of second gaps which are concavely arranged; the second non-metal layer is filled into the second gaps. Therefore, the forming of the interference coupling current can be reduced and communication function of the antenna can be avoided when the first shell coincides with the second shell.

Description

technical field [0001] The invention relates to a communication device, in particular to a communication device for reducing double-layer metal coupling current. Background technique [0002] refer to figure 1 , which is a portable communication device 9, such as a mobile phone or a notebook computer, comprising an upper casing 91 and a lower casing 92 that can be folded and folded relative to the upper casing 91, and the upper casing 91 is provided with The display screen is provided with elements such as buttons on the surface of the lower casing 92, and a circuit board (not shown) for laying out the circuit is provided inside the lower casing 92, and a pivot connection near the lower casing 92 is provided on the circuit board. The hidden antenna 93 below the end. [0003] With the demand of portable communication device 9 light, thin, small and large screen, it is more common to use materials such as aluminum-magnesium alloy instead of thicker plastic materials as the s...
