New description: [New technical field] This kind of micro-drum _ structure, especially __ antenna structure such as printed circuit board material is fixed plate with copper foil linear arrangement of light-emitting components. [Prior Art] Due to the compaction and multi-functional requirements of mobile communication products, such as mobile phones, the antenna architecture will also shrink as the volume, from the open-air line _ Tibetan-style planar antenna, to the micro-chip antenna In order to comply with the design trends of the action products. The structure of the microchip antenna is mainly based on a layer of dielectric layer with a "radiator" layer and then packaged. Refer to the improvement of the new patented microchip antenna of the Republic of China", _7863 "wafer antenna ", invention patent 12_" "dual-frequency single dipole chip antenna", 1256175 "- kinds of double-chip (9) antenna" and other previous cases. The micro-crystal 读 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ . And some shouting of the chip antenna, in order to realize the situation, when there is a large clearance area, in order to achieve a good Wei, but this situation is always worse after the customer installed capacity, need to be improved. [New Content] 3 M391731 This creation provides a miniature antenna architecture consisting of a substrate and an antenna structure. A ground plane and a clearance area are formed on the surface of the substrate. The antenna structure is disposed in the clearance area, including a radiation element and a slab; the fixed plate is made of a printed circuit board material, and the ray element is (4) φ linearly arranged (layGut) on the surface of the slab. By this structure, the complex process and high-efficiency of the conventional crystal antenna are improved, and the minimum space is used to achieve good performance, so that the mobile communication product is lighter in weight, smaller in size, and more effective. In the 'design time', the net (four) range between the sky structure and the ground plane is reduced, so that the variation of the antenna performance is minimized during simulation and installation. In the following, the structure and function of the _ will be added in detail according to the embodiment of the figure. [Embodiment] Referring to Fig. 2 and Fig. 2, the micro antenna structure of the present invention is composed of a substrate 丄〇 and an antenna structure 20. A ground plate 1 i and a clearance area i 2 are formed on the surface of the substrate 10; the length and width of the clearance area are 2 Gmm X 4.2rara' see the second figure without any metal interference therebetween. An antenna structure 2 Q is disposed on the clearance area 12, and reference may be made to the third, third, and third diagrams, including the radiation reading 2 and the fixing plate 22. The fascia 22 is made of a printed circuit board material, and is fading B. The radiating element 2 is linearly laid on the surface of the fixed plate 22. The 1U fixed plate 2 2 of the antenna structure is disposed at the middle position of the clearance w 2 , and the length, width and height of the dimension are d X 4 mm X 2 off. The touch element 2 is an inverted FP antenna with functions such as work as fresh 2 to 2 ships and 4 tests 4 M391731 ~ 5. 9 GHz to apply to the 802. llabg system. In the design of this creation, in order to meet the needs of the installed mobile communication products, the minimum space is used to achieve good performance. As shown in the figure, it is simulated by the actual machine condition. Unlike some ceramic wafer antennas, there must be a large clearance area to achieve good performance, and such a situation always deteriorates after the customer installs the machine; This problem has been taken into account when creating the design, so that the variation in performance during simulation and installation is at a minimum. Refer to the fourth, fifth, and sixth figures for the performance data of the test and test. It can be seen that the creation has good performance in the dual frequency band of 2. 4GHz~2. 5GHz and 4. 9GHz~5_9GHz. The main advantages of this creation are at least as follows: 1) In the design of this creation, the most important is to save costs, simple process, reduce production and processing hours, and improve product production yield. 2) The performance of the simulation test and the actual test error of using the mobile communication product are small. 3) Light weight, small size and good performance. The miniature antenna architecture provided by the author's creation is in full compliance with the patent novelty and progressive requirements.
