INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an antenna, and more particularly to an antenna structure that is suitable for use in a communication electronic product to achieve space saving. It can include mobile phones, notebook computers, digital TVs, cars and wireless LANs. [Prior Art] In recent years, due to the rapid development of wireless communication technology, mobile phones have become the most important communication aid for people. Wei's demand for mobile phones is also large in size from the early stage, the antenna is exposed, the appearance is dull, Wei Xian, the development of Wei is (four) short, the antenna is hidden, and the appearance is more cover-like/monthly cover, etc., and the net is added. The functions of roads, cameras, and playing songs have made the hand _ sacred to the realm of multi-ship entertainment. However, as the size of the mobile phone shrinks, the weight becomes lighter, and at the same time, more functional modules are built in, which makes the space available inside the mobile phone less and less, which also compresses the radiation emitted and received by the microwave (Radiator commonly known as The available space of the antenna). And time-consuming, to improve the manufacturing cost of the FPC antenna on the market for the PCB board process, the radiator needs to be exposed, developed, electric, m-section printing, riding, cutting and other processes, the production of the shaft is complicated ‘A In the blueprint of the big towel field and the communication products of the regional wireless network, the product production system is 34. The development trend of future mitigation products =: short and small minimization, related accessories, such as antenna * Τ Adjustments In addition to the changes in appearance, the internal electrical and institutional engineering needs to be adjusted in a timely manner and __quality_ability. Furthermore, by the development and application of _Communication 200845468, it has gradually moved the notebook computer to the notebook computer in the area network without the regional network, so that it can be used in the mobile communication system. The outside world is connected to suit various communication electronics. Therefore, it is necessary to design such as the handle antenna structure, the product needs. SUMMARY OF THE INVENTION - She is provided with a type of antenna, a coffee-clear film, a layer of acoustic layer, a layer of gold auditorium, and a second layer of adhesive. The thickness of the plastic film is two in G. G3mm, and the thickness of the body layer of Jingu is less than that of Qing. The department will be _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It shoots Osaki low (four) product, and effectively strengthens the miscellaneous room, the electronic product domain, the effect of saving space. In addition, the present invention provides a method for manufacturing an antenna of the type _, the money first cuts out the golden radiator layer and then forms the first and second adhesive layers on both sides of the metal radiator layer, and presses the _ layer positioning device under the pressure Fits to the metal radiator layer and conforms to the release paper. After the completion of each layer, _ light _ reposition, the finished product is cut out. In the manufacturing method of the film type antenna provided by this month, only the metal radiator layer requires soil and H process processing efficiency can be greatly improved, and the cost and product price can be effectively reduced, which is better than the FPC antenna. The following 'will be used to reinstate the structure and manufacturing method of the present invention. 200845468 [Embodiment] Referring to the first to second figures, a film antenna of the present invention mainly comprises a plastic film 1, a first adhesive layer, a metal radiator layer 3, and a second layer. The adhesive layer 4 and a release paper 5 are formed. The plastic film 1 may be a polyester film (PET film, polyethylene terephthalate filni), and the metal radiator layer 3 may be made of a copper foil. The thickness of the plastic filmmaker is less than 〇·〇3 coffee, and the thickness of the metal radiator layer 3 is less than 〇〇25, and the thickness of the first and second adhesive layers 2 and 4 is less than 〇·〇5 to form a Membrane antenna. The release paper 5 is attached to the first knee layer 4, but when combined with the communication electronic product, the release paper 5 is peeled off so that the second adhesive layer 4 can be attached to the communication electronic product. The thickness of the release paper 5 is less than 〇 2 legs. The film antenna of the present invention has a size specification of 3 tex 8 mm x 0.355 coffee, an operating temperature of -40 ° C to +85 ° C, and an operating frequency of GSM _, GSM 18 〇〇, (10), CDM, and WCDMA. The invention mainly covers the metal layer|metal layer 3 in the plastic film 1 and utilizes the flexible property of the plastic film 1 to make the whole film antenna easy to be fixed in the compact product, occupying a small volume, and The effective paste space is fixed inside the communication electronic product to achieve space saving effect. Into the second, the present invention provides a method for manufacturing the thin film antenna, the steps of which are: a) cutting a metal sheet 'cutting a metal sheet, such as a copper box, into a metal light body layer, and Forming a positioning point thereon; 200845468 b) coating the glue, forming a _adhesive layer on the surface of the metal paving layer; C) forming a plastic film by punching and forming a positioning point; d) positioning and pressing 1 According to the light and smelting, the glue e) is glued to form a second rubber layer on the other side of the metal radiator layer; f) the release paper is attached, and the release paper is attached to the second adhesive layer. ; and g) The outer shape is cut out, and the finished product is cut out by optical compensation positioning. In the manufacturing method of the present invention, only the metal radiator layer needs to be cut and manufactured, and the processing rate can be greatly increased, and the cost and the product price can be effectively reduced, which is much lower than that when the antenna is in the external cutting process. The internal metal radiator layer shall not be damaged, and the error shall not be greater than 0·lmm. The finished product is subjected to electrical testing in accordance with electrical test specifications. Another, Cheng.
