Description of the Invention: [Technical Field of the Invention] The present invention relates to an antenna element. [Prior Art] The antenna of the wireless communication terminal mainly has two types of built-in antennas and external antennas. Compared with the external antenna, the built-in antenna can effectively reduce the size of the wireless communication terminal. Therefore, the current wireless communication system generally adopts the design of the built-in antenna. Please refer to FIG. 1 'The wireless communication terminal Φ end adopting the built-in antenna design includes a shell layer 91, an antenna layer 92', an inner shell layer 93, a tantalum conductive terminal 94, a circuit board (not shown) and connected thereto. A flexible guide column 9 5 of the circuit board is described. The outer skin layer 91 is typically a enamel decorative plastic film for carrying the antenna layer 92. The antenna 92 is formed or attached to the outer casing layer 91 and interposed between the outer layer 91 and the inner casing layer 93. One end of the conductive terminal 94 is in conductive contact with the squall layer 92, and the other end of the conductive terminal 94 is in conductive contact with the elastic pillar 95 through the inner shell layer 93, thus realizing radio signal communication between the antenna layer 92 and the circuit structure of the circuit board. . However, the design of the antenna needs to consider the implementation of multiple Φ = energy of the antenna. However, the conventional antenna element is generally a single antenna, so it is necessary to design a plurality of antenna elements to achieve multi-function, so that the antenna element is occupied. The wireless communication terminal has more space, which is not conducive to the multi-reality of the wireless communication terminal to be cracked. The essentials must be wired, and the inner space of the space can be used to save energy in the province. 2010 20103535 In addition, it is necessary to provide a method for fabricating the antenna element. In addition, it is necessary to provide a housing in which the antenna is integrated. An antenna element comprising: a layer, at least one dielectric layer and at least two antenna layers, wherein the dielectric layer and the at least two antenna layers are alternately laminated on the support, the carrier layer being a resin film. An antenna element method having a multilayer structure, comprising the steps of: providing a resin film; alternately laminating at least two days and at least one dielectric layer on the resin film, the at least two antenna layers being printed using ink . A housing comprising an injection molded layer and a day piece, the day j-line component comprising: a carrier layer, at least one layer and at least two antenna layers, the at least one dielectric layer and the two antenna layers are alternately stacked on the carrier layer Above, the bearing is a resin film, and the injection molding layer is injection molded and bonded to the φ piece. Compared with the prior art, the antenna element multi-layer antenna of the invention can realize the multi-function of the antenna and save the design space. [Embodiment] Referring to FIG. 2, a case 20 of a preferred embodiment of the present invention includes a carrier layer 21, a plurality of antenna layers 22, and a dielectric layer 23. The carrier layer 21 may be a molding film in an in-mold decoration process, which is a polycarbonate resin film, an acrylonitrile-butyl-piece component carrier---a square layer of a carrier layer, a conductive line element dielectric layer, at least a carrier layer line. The element has a plurality of antenna elements contained in the diene- 4 201027835 styrene copolymer resin film and a polyethylene terephthalate resin film. Each antenna layer 22 is formed by printing to form an electro-ink layer having a radiation pattern of the antenna. The layers 22 may be primary antenna radiation auxiliary antenna light emitters in the antenna elements, respectively. Each of the dielectric layers 23 is a non-conductive ink layer formed in a printed manner between the antenna layers 22. The day 22 is alternately laminated with the dielectric layer 23, and the antenna layer 22 is spaced by the layer 23. A conduction portion 24 may be formed between the antenna layers 22. The electrical conduction portion 24 can be electrically connected to the adjacent two antenna layers 22 by conductive ink. At the time of fabrication, the conductive ink is applied to the carrier layer 21 by an antenna radiation pattern to form an antenna layer 22. The non-conductive ink is printed on the antenna layer 22 and a dielectric layer 23; wherein, when the non-conductive ink-shaped electrical layer 23 is printed, the printed pattern of the dielectric layer 23 can be designed to form the antenna layer 22 after the dielectric layer 23 is formed. The conductive joint is required to be exposed. φ printing a conductive ink on the dielectric layer 23 to form a double layer 22, and the conductive ink is also formed on a portion where the first antenna layer 22 needs to be in conductive contact. At this time, the conductive ink at the conductive contact portion That is, the electrical portion 24 can be electrically connected to the adjacent day 22 by the electrical conduction portion 24. Thus, the antenna layer 22 is formed alternately by alternately forming the antenna layer 22, i.e., the multilayer structure of the antenna element 20 can be obtained. Each of the antenna layers 22 can be used to achieve different powers, respectively, saving space in the antenna design. The conductive antenna body of the diol and the wire layer are dielectrically formed, and the film is formed to form a conduction line layer and a dielectric junction energy one day before the touch, 5 201027835 It is understood that the dielectric layer 23 is also It may be a non-conductive resin lacquer layer formed by a spraying process. It can be understood that the antenna layer 22 can also be omitted from the electrical conduction portion 24, and the antenna layers 22 can be electrically disconnected from each other. Each antenna layer 22 can be connected to a circuit board by a cable (such as a copper wire). Thereby the conduction of radio signals is achieved. The antenna element 20 of the preferred embodiment of the present invention can be directly integrated into the housing of the wireless communication device. Referring to FIG. 3, the housing 100 of the wireless communication device of the preferred embodiment of the present invention includes an injection molded layer 30 and the antenna® wire member 20. The injection molded layer 30 may be a resin layer such as a silicone resin or a thermoplastic resin which is bonded to the antenna element 20 by injection molding. When the casing 100 is formed by injection molding, the antenna element 20 is placed in an injection molding die (not shown) having one side of the carrier layer 21 attached to the injection molding die. In the case of injection molding, the injection molded layer 3 is formed on one side of the antenna element 20 with respect to the carrier layer 21. When the outermost layer of the side φ of the antenna element 20 opposite to the carrier layer 21 is the antenna layer 22, the injection molded layer 30 is bonded to the antenna layer 22. When the antenna element 20 includes at least two dielectric layers 23, the outermost layer of the antenna element 20 opposite to the carrier layer 21 may be a dielectric layer 23, and the injection molding layer 30 may also be injection-molded to the dielectric layer 23. on. At this time, the injection molding layer 30 does not directly impinge on the antenna layer 22 in the injection molding, so that the pattern of the antenna layer 22 is not easily broken, and at the same time, the antenna layer 22 can be prevented from being oxidized in the injection molding. 6 201027835 The housing 100 of the preferred embodiment of the present invention integrates a multi-layered antenna element 20 to facilitate reducing the size of the radio.
