Embodiment 1
[0058] The housing assembly structure of the present embodiment is like figure 1 Indicated. Among them, the material of the housing 11 is glass, the bonding layer 121 is a adhesive, and the substrate 132 is a PET film. The conductive silver paste is used, and the frequency selection surface structure consisting of a plurality of circular cells is printed by the screen printing process. The arrangement of the plurality of circular units is arranged. Figure 28 The rectangular array shown, each of the circular cells is 0.5 mm, and the distance between the center of the adjacent two circular units is 1 mM to obtain the transmission layer 13a. The transparent wave layer 13a is attached to the housing 11 by the adhesive layer 121 to obtain a housing assembly, the housing assembly having a total thickness of 0.7 mm.
[0059] Test the reflection coefficient and transmitting coefficient of 20 to 34 GHz, the test result is: the scattering coefficient of 22.4 GHz ~ 29.5 GHz after the housing...
Embodiment 2
[0061] The housing assembly structure of the present embodiment is like Figure 9 Indicated. Wherein, the material of the housing 11 is glass, and the decorative layer 122 is a CMF diaphragm. The conductive silver paste is used, and the screen printing process is printed by the screen printing process by the remote from the housing 11 of the decorative layer 122, the frequency selection surface structure consisting of a plurality of square units, and the arrangement of the plurality of square units is a rectangular array, each square The radius of the unit is 1 mm, the distance between the two square units is 2 mm, and the transmission layer 13f is obtained; and the conductive silver paste is used, and the wire screen printing process is printed from the side of the housing 11 of the decorative layer 122. The frequency selection surface structure consisting of multiple grid units, and the arrangement of multiple grid units is like Figure 11 The rectangular array shown, the line wid...
