New description: [New technical field] This creation is about a planar inverted F antenna, especially a wireless communication device _ small antenna, which can be assembled automatically, and the structure has good stability. [Prior Art] With the advancement of wireless communication technology, many electronic products are combined with wireless communication modules to communicate with remote devices, such as notebook computers, p d a or mobile phones. Among them, Planer lnverted F Antenna (PIFA) has been widely used as a built-in type or embedded antenna for mobile communication products because of its light weight and (4) material point. For example, FIG. 2 is a conventional planar inverted F-type antenna 9 having a rectangular plate-shaped ejector element 9 1 and a grounding element (also referred to as a grounding element below the Kosei projecting element 9 1 ) 〇und eiement) 9 2. The radiating element 9 is [parallel to the grounding element 92 and extends downwardly to a grounding pin 9 3 and a signal pin 9 4 , wherein the grounding pin 9 3 is electrically connected to the grounding element 9 2 , The signal pin 94 passes through the grounding element 92 and is electrically connected to a radio transceiver circuit (not shown) as a signal feed pin. Thus, when the radiating element 91 senses an external electromagnetic wave, the signal is introduced into the radio transceiver circuit through the signal pin 94. Alternatively, the radio transceiver circuit can also cause the radiating element 9 1 to emit electric waves through the signal pin 94. Such an antenna is so close to the ground pin 9 3 and the signal pin 94 that its structure is not sufficiently stable. In order to fix the planar inverted-F antenna 9 M307864 and the strength of the reinforcing mechanism, a pair of spacers 9 5 and 96 made of an insulating material such as sponge or acryl are usually inserted into the rotating component 9 . Between the work and the grounding element 9 2 . Since the gasket cannot withstand high temperatures, the antenna needs to be soldered before the step of mounting the gasket, which not only increases the antenna cost but also reduces the emission efficiency. In addition, due to the need for manual assembly, it cannot be automatically assembled on the circuit board, resulting in production. Assembly speed cannot be improved. For the improvement of antenna stability, structural strength and assembly capability, the prior art has a multi-frequency antenna disclosed in U.S. Patent No. 6,738,023, issued May 18, 2004. The frequency antenna has a plastic flat △ and four metal pins for direct soldering to the circuit board. The radiating element is: disposed on the plastic platform, and the plastic winning platform is formed by using a micro-embedded human scale method, and the plastic sheet is formed by punching and forming, and then embedded in the plastic flat by the process. . This technology still has the disadvantage of complicated manufacturing technology and high cost. In addition, the related prior art also has a US patent, US 6,85G, 2GG, which is announced in the 2nd, 5th, 2nd, 2nd year, "Plane inverted type = supply - support structure is engaged in radiation (4) and signal connection 』(4) j-end' The structure is made of insulating material and can be directly fixed to the circuit board by the reflow oven for automated assembly. The point is that the supporting structure is bulky and it is easy to increase the dielectric effect (dieiectric e e c t ), the shape is complicated and the manufacturing is difficult, and the material is special and the cost is increased. 1 person feels that the above-mentioned lack can be improved, and the use of the lack of research is proposed, and the design is reasonable and effective to improve the above [new content] M307864 The main purpose is to provide a planar inverted f-type antenna, not only the surface structure It can effectively reduce production costs and can be directly soldered to the board using Surface Adhesive Technology (SMT) to increase assembly speed.
