[Prior Art] With the increasing popularity of wireless communication technologies, antennas have become one of the essential components of many electronic products, such as mobile phones, satellite navigation devices, and the like. Generally, the antenna body has a - or two-peel contact, such as a feed point and a ground point, for electrically connecting the circuit board in the disk electronic device, so that the antenna transmits or receives radio waves, due to the antenna_ The design usually costs the electronics outside the age of the electronic product. Therefore, for convenience, it is usually fixed at the position of the antenna, and then connected to the interface and circuit board of the antenna through the cable and the connection. In general, the switching view of high-frequency signals is often ___ connectors, such as SMA connectors, CX connectors and IPX connectors, etc. to provide better impedance matching and avoid signal degradation. However, the high-frequency signal relay and adapters are expensive, which will increase the number of electronics.

Preferably, the antenna fixing mechanism 11 ejects the formed Na-piece according to the shape of the metal antenna. Further, the day making mechanism u may further include - (4) 112 for providing a space for accommodating the deformed metal dome 122 when the antenna fixing mechanism 11 is fixed to the circuit board 13. On the other hand, the metal antenna 12 may further include a conductive copper foil 124' coupled to a grounding point of the metal antenna 12 for increasing the ground contact area of the metal antenna. In the present embodiment, the antenna fixing mechanism 11 locks the antenna fixing mechanism 11 to the circuit board 13 by means of screws and screw holes. Therefore, the present invention can surely fix the antenna on the circuit substrate. In addition, when the antenna is locked on the circuit board, the creation of the antenna is electrically connected to the corresponding contact point on the circuit substrate by the elastic characteristics of the metal dome. In this way, even if a collision occurs after the installation, the electrical connection between the antenna and the circuit board does not break or fall off, so that the signal contact failure can be avoided. Please note that in this embodiment, the metal antenna 12 is designed in the form of a Planer Inverted F Antenna (PIFA), which can be used to transmit Bluetooth signals or conform to 802.11 a/b/g, Zigbee, Wimax. The wireless signal of the protocol. However, in other embodiments, the metal antenna 12 can also be designed in other antenna forms, such as a Monopole antenna, a Dipole Antenna, or a 5 M397039 Loop Antenna to meet various electronic technologies. The needs of the device. On the other hand, in the present embodiment, the antenna fixing mechanism u is fixed to the circuit board 13 in a locking manner. However, in other embodiments, the antenna fixing mechanism can be fixed to the circuit substrate by other means S1, and the signal of the antenna can be electrically connected to the corresponding contact point on the circuit board when the antenna is fixed. It belongs to the scope of this creation. For example, please refer to Figures 3 and 4, and Figures 3 and 4 are schematic views of an embodiment of an antenna mechanism 30. In this embodiment, the antenna mechanism 3 is used to fix the antenna fixing mechanism to the circuit board 33 in a sliding manner. Therefore, the antenna mechanism 30 is provided with a sliding mechanism of the antenna fixing mechanism 31 on one of the housings 34 of the electronic device; when the antenna fixing mechanism 31 completes the sliding rail travel, the metal elastic piece 322 of the metal antenna 32 is deformed and the circuit The antenna contact points 332 on the substrate 33 are in close contact. In addition, in the embodiment, the metal antenna 32 further includes a metal dome 324 as a grounding point of the metal antenna 32. At this time, the circuit substrate 33 is additionally provided with an antenna contact point corresponding to one of the metal domes 324. When the antenna fixing mechanism 31 is fixed on the substrate in a sliding manner, the metal domes 322 and 324 are simultaneously electrically connected to the corresponding antenna contact points 332 and 334 on the circuit board. Therefore, in addition to the fact that the antenna can be securely fixed on the circuit substrate, the antenna ground point and the feed point can be electrically connected to the circuit substrate at the same time. Please refer to Figure 5 and Figure 6. Figure 5 and Figure 6 show an example of an embodiment of an antenna mechanism 6 M397039 « · t » 5〇. In this embodiment, the antenna mechanism 50 is attached in a flip-flop manner to the antenna substrate. In this case, the circuit substrate 53 has the latch 56, and the antenna fixing mechanism has a slot 57 such that the antenna fixing mechanism 51 is unilaterally fixed on the plane of the board. Further, the other end of the antenna fixing mechanism 41 has a button design 516' on which the antenna mosquito mechanism 51 is press-fitted to the electric board 53. When the antenna fixing mechanism 51 is press-fitted and fixed on the circuit substrate 53, the metal dome 522 (that is, the feeding point of the antenna) is electrically connected to the corresponding antenna contact 532 on the circuit substrate 53 due to the deformation. The metal folding antenna can emit and receive wireless signals. Therefore, the antenna mechanism of the present invention can be designed to improve the contact method or mode of the antenna feed point and can be used under different external structure design and antenna concept design, such as an early pole antenna, a dipole antenna or a loop antenna. For example, when the antenna is designed in the form of a monopole antenna or a dipole antenna, the present invention can fix the antenna on the circuit substrate by using a compression method, and when the antenna is designed as a loop antenna or a planar inverted F antenna, The antenna can be fixed to the circuit substrate by a locking method and a sliding method. In short, the original creation of the antenna is electrically connected to the corresponding contact point on the circuit substrate by the elastic characteristics of the metal dome. In this way, even if a collision occurs after leaving the factory, the electrical connection between the antenna and the circuit board will not be broken or dropped, so that the signal contact failure can be avoided. The above is only the best of the creation. The average and the modification made by the author's application scope 7 /ujy, Wei is a secret.
