[0042] According to another aspect of the present invention, a method for preparing an antenna device is provided, such as figure 2 shown. The preparation method includes the following steps: preparing the core material layer 20; laying a main fiber prepreg layer on the inner surface of the mold, and the main fiber prepreg layer is composed of a conductive fiber prepreg layer and a conductive fiber prepreg layer. It consists of insulating fiber prepreg layers connected all around; connect the sides of the mold so that the main fiber prepreg layer wraps the core material layer; perform curing treatment to cure the conductive fiber prepreg layer to form a conductive fiber composite material layer 110, And make the insulating fiber prepreg layer form the insulating fiber composite material layer 120 .
[0043] In the above preparation method, since the conductive fiber composite material layer is used to form the main fiber composite material layer of the antenna device, that i...
