In the first embodiment, the light metal portion 12 and the short metal portion 16 are connected to the ground. The ground 11 is stamped or cut from a single piece of metal, and the antenna of the present invention has the advantages of electromagnetic compatibility characteristics, and is suitable for being integrated in a wireless communication product to achieve a dual-frequency operation communication function. FIG. 2 is an antenna of the present invention. A structural view of a first embodiment and a structural view of an adjacent metal member 21. In the present embodiment, an adjacent metal member h is placed having a length of about 20 mm and a width of 20 mm, and the distance from the antenna of the present invention is d. Fig. 3 is a return loss measurement result of the antenna of the present invention 1336153 -. In the first embodiment, in order to consider the built-in grounding environment of the notebook computer LCD screen, we select the ground plane u. The length of the first metal arm 13 is about 90 mm and the width is about 2 mm. The length of the second metal arm 14 is about 30 mm and the width is about 2 mm. The second metal arm 15 has a length of about 14 mm and a width of about 2 mm; the length of the short-circuited metal arm 17 is about 2 mm and the width is about 6 mm; the length of the connecting metal arm 18 is about 21 mm and the width is about 2 mm. From the experimental results, the return loss is less than 6 dB. By definition, the bandwidth of the operation covers the global communication system (GSM, 89〇~ 960 MHz) and digital communication system (DCS, 171〇~188〇“Hz) required by the wireless wide area network (WWAN). Operational requirements. Figure 4 is a result of the return loss of an embodiment of the antenna of the present invention and an adjacent metal component 2i; in the case where the adjacent metal component 21 is not placed, the curve 41 obtained by the antenna of the present invention is closely attached to the adjacent metal component, respectively. The curve 42 obtained by the antenna of the present invention, the curve 43 obtained when the distance between the adjacent metal element and the antenna of the present invention is 5 mm, is small. It can thus be seen that the antenna of the present invention substantially reduces the proximity of the metal component 21 on the ground 11 by shorting the metal portion 16 to an embodiment of the antenna of the present invention. / Figure 5 is a structural view of a first other embodiment of the antenna of the present invention, wherein the first sub-metal arm 13 and the third sub-metal arm 15 have more than one bend f' to thereby reduce the height of the antenna of the present invention. At the same time, the short-circuited metal drill fixing hole 51 is used to make the antenna of the present invention in practical use. The structure of the second embodiment of the present invention is substantially the same as that of the second embodiment of the present invention. However, the radiant metal portion is short and the metal portion 16 is formed on the microwave substrate 61 by printing or etching technology, thereby reducing the size of the antenna of the present invention and further reducing the size. The embodiments described in the above description are merely illustrative of the principles and functions of the invention and are not intended to limit the invention. Therefore, those skilled in the art can make modifications and changes to the above embodiments without departing from the spirit of the invention.
