New description: [New technical field] This creation relates to an antenna structure, especially a transparent metal film antenna structure in which a metal film is directly formed on a transparent substrate. [Prior Art] Due to the rapid development of wireless communication technologies, electronic devices, such as mobile phones, notebook computers, and PDAs, often have this function to achieve rapid data transmission. In wireless communication technology, an antenna must be configured in an electronic device to provide wireless communication. Traditionally, there are vertical and flat antennas, mostly in the shape of a copper design to form a radiator, and connected to a circuit board in an electronic device. These conventional antennas, because the light-emitting bodies made of copper are mostly hard structures, will occupy the space of the # when installed in electronic equipment, which is not conducive to the requirements of compaction. In particular, in the traditionally made antennas, the steel materials used for the fortune will be used in the current high materials, which is not conducive to cost and needs to be improved. [New content] In view of the shortcomings of the conventional antenna, the present invention provides a transparent metal thin-twist antenna structure, which comprises a transparent substrate and has flexibility; and a metal film, the shape of which constitutes a signal feed The radiator of the inlet portion is directly formed on the surface of the transparent substrate. M334481 The metal film of this creation can be made of copper, which can reduce the manufacturing cost by using less copper material. At the same time, due to the flexibility of the metal film and the substrate, this creation provides The antenna structure can occupy a minimum of space and is suitable for installation in various electronic devices to facilitate the mechanical design of the electronic device. Hereinafter, the features and effects of the present creation will be described in detail based on the embodiments shown in the drawings. [Embodiment] Referring to the first figure and the second figure, the transparent metal film antenna structure provided by the present invention is mainly composed of a transparent substrate 1 and a metal film 2 directly formed on the surface thereof. The transparent substrate 1 has flexibility and is made of a polyester film (pET) which is excellent in elongation and density. The shape of the metal film 2 constitutes a radiator having the signal feed portion 21, and is integrally molded directly on the surface of the transparent substrate 1. In this creation, since the metal film is a thin layer of copper, the amount of copper used to form the radiator is small, and the transparent substrate 1 can be wound or folded to be deformed to suit different installation environments. The space occupied by the antenna. At the time of manufacture, as shown in the third figure, a plurality of metal thin films 2 are formed on a transparent substrate 1, and then the transparent substrate 1 is cut to form a plurality of individual transparent metal film antennas. structure. Therefore, this creation is also conducive to the production cost and time savings. The joining method of the metal thin film 2 and the transparent substrate 1 of the present invention may be a method of sputtering, printing, or pasting, and the metal thin film 2 is attached to the transparent substrate 1. The drawings show only a preferred embodiment of the present invention, but the scope of the patent application is not limited thereto, and the shape change of the radiator is still within the scope of the patent protection. 6 M334481 [Simple description of the diagram] The first diagram represents the exploded view of the creation, the second diagram represents the combination diagram of the creation, and the third diagram represents the plan view of molding a plurality of metal films on the transparent substrate during the creation of the creation.
