It is paid in the lock firmware 211. The value of the present invention has been described in the present embodiment. Although the locking method has been described, the sub-substrate 220 is fixed to the casing 21 through the main body portion 231. However, the skilled person should know that the locking manner of the body portion 231 and the locking member 211 includes a plurality of types. Therefore, as long as the body portion 231 of the antenna 230 is used to fix the substrate 220 to the housing 210, it is already It is in line with the spirit of the present invention. For example, an exploded view of the housing and the substrate illustrated in FIG. 3 is taken as an example. Referring to FIG. 3, when the upper casing 212 has a guide hole 241 corresponding to the lock 211, the body portion 231 is further inserted into the lock 211 through the guide hole 24i. In other words, the body portion 231 at this time is fixed to the fastener 211 through the guide holes 241 and 221 at the same time, so that the substrate 220 is more stable in the housing 210. In addition, since the body portion 231 is locked in the locking member 211, that is, the body portion 231 and the locking member 211 are coupled to each other, when the material of the locking member 211 is a metal material, the antenna 23 is further changed. The firmware 211 is used to receive or transmit electromagnetic signals. It should be noted that the lock 211 listed in this embodiment may be a nut or a self-tapping. 4 is a schematic structural diagram of a wireless communication device according to another embodiment of the present invention. Referring to FIG. 4, the wireless communication device 400 includes a housing 410, a substrate 420, an antenna 430, an impedance matching circuit 440, and a transceiver 450. The substrate 420 and the antenna 430 are disposed in the housing 410, and the impedance matching circuit is provided. The 440 and the transceiver 450 are disposed on the substrate 420. 201010178 jljl a wvxw25-0-TW^ 24094-ltwf.doc/n The operating mechanism of this embodiment is similar to that of the embodiment of Fig. 2, and the antenna 430 is used to receive or transmit an electromagnetic signal. The impedance matching circuit 440 is used to reduce the energy loss formed by the electromagnetic signal during transmission, so that the transceiver 450 can receive the complete electromagnetic signal in cooperation with the antenna 430. In contrast, the transceiver 450 will also transmit a complete electromagnetic signal to the antenna 430 through the impedance matching circuit 440. However, the present embodiment is largely different from the embodiment of Fig. 2 in that although the antenna 430 exemplified in the present embodiment has the function of fixing the substrate 420, the fixing manner is different from that of the embodiment of Fig. 2. For example, referring to FIG. 4, the antenna 430 includes a body portion 431 and an extension portion 432, and the body portion 431 includes a first component 41 and a second component 42. Here, the first component 41 fits into the side shape of the substrate 420 to form a recess so that the side of the substrate 420 can be fitted to the first component 41. On the other hand, since the second component 42 is connected to the first component 41 and fixed to the casing 41, the substrate 420 can be fixed in the casing 410 through the antenna 430. It is to be noted that the 'extension portion 432 is disposed above the substrate 420 and is interconnected with the first component 41. In this way, the antenna 43A can simultaneously utilize the body portion 431 and the extension portion 432 to receive or transmit electromagnetic signals. Moreover, in the present embodiment, the housing 410 includes a lock 411, an upper housing 412, and a lower housing 413. The upper casing 412 and the lower casing 413 are stacked on each other and form a cavity to accommodate the substrate 420 and the antenna 430, and the fastener 411 is fixed to the lower casing 413 at a position corresponding to the second component 42. So that the second component 42 can be locked in the lock 411. In addition, the material of the main body portion 431 and the extending portion 432 are made of metal material 9 201010178 m ^υ^υν/^ju-TW 24094-ltwf.doc/n*, for example, the material constituting the second component 42 includes Shao and steel. , do not record steel, iron, copper, phosphor bronze or beryllium copper, and on the surface of metal materials, can also be plated with metals, such as nickel, zinc, etc. On the other hand, the second component 42 exemplified in the embodiment may be a screw, the extending portion 432 may be a metal wire, and the locking member 411 may be a nut or a self-tapping. Other details of the embodiment are included in the above embodiments, and thus will not be described herein. In summary, the wireless communication device of the present invention utilizes an antenna to receive or transmit electromagnetic signals and the antenna has the function of fixing the substrate and the housing. Therefore, compared with the prior art, the present invention can effectively reduce the hardware space of the wireless communication device, thereby causing the wireless communication device to achieve miniaturization. While the invention has been described above by way of a preferred embodiment, the invention is not intended to be limited to the scope of the present invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims.
