Field of the Invention The present invention relates to a 'type antenna structure, and more particularly to an antenna structure in which a radiating element is linearly arranged with a copper foil by using a printed circuit board as a fixed plate. [Prior Art] Due to the compaction and multi-functional requirements of mobile communication products, such as mobile phones, the antenna architecture must also follow the shrinking footprint, from the outside open line to the hidden planar antenna, and then to the microchip antenna. In line with the design trends of mobile communication products. The structure of the microchip antenna is mainly composed of a light emitter layer on a layer of dielectric layer, and is woven and repackaged. Refer to the improvement of the Chinese _ patent 眶122 microchip antenna, M307863" "Antenna", invention patent 126 "Double-frequency single dipole chip antenna" '25656" "--------------------------------------------------------------------------------------------------------------- The cost 'especially in the spread of the wafer raising (four) layout money extensions to the design of the foot more complex '1 in the line riding down products. And some _ wafer field, in order to have a real machine situation - a large clearance area 'right to good, the status of the bee sample is always worse after the installed capacity of each household, need to be improved. [Summary of the Invention] Cheng 5 200845472 package t-touch components and - map; Langding board system brushing secret board material, ^ shoot farming system, for copper Cheng miscellaneous arrangement (la_t) _ fixed plate surface. In order to: read the complex process and high cost of the traditional chip antenna, and use the minimum space to achieve a good Wei, so that the product weight reduction, body small domain can be good. In addition, when designing on this side, the financial area of the antenna and the ground plane is reduced, and the variation error of the lining performance when the handle is installed and installed is in a minimum range. In the following, the structure and effect of the sun and the moon will be added to the actual details shown in the flip. [Embodiment] Referring to the first and second figures, the micro antenna structure of the present invention is constructed by a substrate process and an antenna structure 20. A ground plate 11 and a clearance area 形成2 are formed on the surface of the substrate 10; the length and width of the clearance area are 2 Gmm X 4. 2 min ′ See the second figure without any metal interference therebetween. An antenna structure 2 is disposed on the clearance area 12, see third, third and third B, including the radiating element 21 and the fixing plate 22. The fixing plate 22 is made of a printed circuit board material, such as FR4 PCB, and the radiating element 21 is linearly laid on the surface of the fixing plate 22. The fixing plate 2 2 of the antenna structure 20 is disposed at an intermediate position of the clearance area 12, and has a length, a width and a height of 12.9 legs X 4 mm X 2 mm. The radiating element 2 1 is an inverted f-type planar antenna having a dual-frequency function, for example, an operating frequency of 2.4 GHz to 2.5 GHz and 4.9 GHz to 5.9 GHz for the 802·llabg system. In the design of the present invention, in order to meet the needs of the installed mobile communication products, the minimum efficiency of 200845472 is achieved. As shown in the figure, it is simulated by the actual machine condition. Unlike some ceramic 曰 antennas, it is necessary to have a large clearance area in the simulation to achieve good performance. The chip-like = film always has poor performance after the customer is installed; At the time of design of the present invention, this problem has been included in the test to minimize the variation in performance during simulation and installation. ~ Refer to the fourth, fifth, and sixth diagrams for the test of the fourth (4) tester. It can be seen that the present invention has good performance in the dual frequency bands of 2·4 GHz to 2. 5 GHz and 4·9 GHz to 5·9 GHz. The main advantages of the present invention are at least as follows: 1) When designing the present invention, the most important is the cost of the process, the process is simple, the production and processing time is reduced, and the production yield of the product is improved. 2) The effectiveness of the model-test and the use of mobile communication products are small. 3) Light weight, small size and good performance. 4 On the Chen's invention provides the Lai antenna structure, fully in line with the progressive requirements, Newtown (four) please.
