Description of the Invention: [Technical Field of the Invention] The present invention relates to an antenna device and a method of fabricating the same. Specifically, it relates to an antenna device manufactured by an in-mold forming process and a method thereof. 6 [Prior Art] In-Mold Decoration (IMD) is a popular surface decoration technology, and its main application is in home appliances. The surface decoration and functional panels of the product, the mobile phone window lens and casing, the washing machine console, the refrigerator console, the air-conditioning device console, the car dashboard, and other appearances of various home appliances such as panels and signs. The technical point of in-mold decoration is to put a film with a pattern into a mold for injection molding (Injection Molding). After the plastic part is formed, the patterned film is integrated with the plastic to make the pattern appear on the surface of the plastic part. The film used in the process is roughly composed of the following three layers: a substrate, an ink, And wealth materials. The substrate is used to carry ink and wear-resistant materials, and the film is in the form of a film or a sheet. The material may be a general polyethylene terephthalate (PET) or a polycarbonate (polycarbonate). PC). The above inks are used to form the desired pattern, or to give the plastic parts a variety of product appearances such as metal, leather, wood grain, stone grain, and the like. The wear-resistant material is placed on the outermost part of the overall object after molding to provide wear resistance, scratch resistance, anti-reflection and the like. The industry has used the above-mentioned conventional in-mold decoration technology to form a printed antenna on the surface of a plastic part for use on small or micro devices that need to use antenna devices to transmit and receive signals, such as various handheld mobile devices. , wireless appliances, or radio frequency identification tags (RFID). In this method, it is only necessary to change the color material used in the original in-mold decoration technology of 201201446 and then print it on the surface of the film (4) into a conductive ink. The relevant library uses the middle right: 2 lines. The above-mentioned printed antenna has the advantage of having a shirt in the application of the sequence, and the frequencies, Q values and impedances are reduced by mj, and the vibration of the whole antenna is the value of the coil, the resistance, and the size of the antenna.

The connection between the wafer module and the antenna pattern in the object is a key part of its manufacturing technology. In the conventional printed antenna technology, a conductive adhesive or a direct press-bonding method is generally used to establish an electrical connection between the printed antenna and the circuit board. However, this is not possible in the case where the antenna pattern is coated between the film and the surface of the plastic part. In this regard, 'the current industry generally will connect the antenna pattern to the wafer after the injection molding process (that is, after the plastic part is molded)', such as through the pre-defined opening on the plastic part, the antenna pattern can be exposed from the plastic part, and then pulled Wires are used to establish the connection. However, this method requires an additional joining step, and the connection reliability established by this method is not good. The design of the joint structure will also increase the thickness required for the overall casting of the plastic part, which is not conducive to the demand for the current electronic device. In view of the many shortcomings of the prior art described above. There is an urgent need in the industry to improve the fabrication methods of conventional printed antennas in order to reduce the manufacturing cost and required steps of the antenna device and provide better performance and reliability. SUMMARY OF THE INVENTION In view of the above-mentioned shortcomings of the prior art, the present invention discloses an antenna device and a method thereof which are fabricated by an in-mold forming process. The antenna device has 4 201201446 an antenna pattern is adhered to the surface of the plastic part. The antenna pattern is electrically coupled to a conductive member fixed in the plastic member, and the conductive member is electrically connected to an external circuit by a portion exposed from the plastic member. The method of the present invention integrates the conductive member and the plastic member by inserting a conductive member in the mold before forming the plastic part in the injection molding step, so that the antenna pattern attached to the surface of the plastic part after molding can be obtained by The conductive member is electrically connected to an external circuit. SUMMARY OF THE INVENTION An object of the present invention is to provide an antenna device in which an antenna pattern is adhered to a surface of a plastic member together with a film by an in-mold forming process, and is electrically connected to an external circuit via a conductive member in the plastic member. An object of the present invention is to provide a conductive member for an antenna device, comprising: a coupling portion having a coupling end electrically coupled to an antenna pattern; and a contact portion coupled to the circuit board; wherein one end of the contact portion The coupling portion is coupled to the coupling portion, and the coupling portion is at an angle with the coupling portion, such that the coupling end of the coupling portion forms a distance from a plane of the contact portion, and the coupling end is from the coupling portion Warping upwards and extending away from the contact. Another object of the present invention is to provide a novel antenna manufacturing method, which is characterized in that a conductive member is placed in a mold to be molded together with the plastic member before the injection molding step, and the conductive member is formed on the surface of the plastic member after molding. The antenna pattern is electrically coupled, and the conductive member is partially exposed from the plastic member. The invention has the advantage that no additional processing steps are required after the molding of the plastic part to electrically connect the antenna pattern with an external circuit, and the reliability of coupling the antenna device to the external circuit can be improved. Another advantage of the present invention is that it allows the conductive member to be molded with the plastic member to reduce the thickness required for the overall plastic part, and the conductive member does not cause significant protrusions on the surface of the molded article 201201446. After reviewing the detailed scope of the following, the reader will be able to apply more patents and related drawings and patents.
