[Prior Art] With the development of wireless communication technology, many electronic products such as mobile phones and notebooks have emerged on the market today, and wireless communication technologies have been widely used to transmit information. With the advancement of line communication systems, the demand for broadband antennas is increasing. In order to comply with wireless communication devices of various frequency bands, antennas with larger bandwidths have become an inevitable trend in the future development of technology. On the other hand, in today's wireless communication technologies, transmission methods using Wi-Fi (Wireless Fi-delity) antennas have become very popular and occupy an important position. In the prior art, the operating frequency required for the Wi-Fi antenna is usually in the range of 2.4 to 2.5 GHz and 5.15 to 5.85 GHz.

Please refer to Figure 1 for Figure 1 Α Antenna Standing Wave Ratio (VSWR). The range of frequencies between 2.5 GHz and 5 GHz can be obtained from ® 1 。. Because of m, the antenna 90 that can be transmitted can only meet the requirements of Wi_F. In the prior art, it is sufficient to cover the bandwidth requirements required for WiMAX antennas. Therefore, it is necessary to create a problem that does not occur in a new boat. v. To solve the prior art [new content] The main purpose of this creation is to provide an antenna with a wide effect frequency for the above purposes. The first part of the creation includes a light-emitting component, a grounding component, and a short-circuit element. (4) The feed antenna includes a first radiation region and a second radiation region, and the first light:: radiation 70 light-light regions are substantially perpendicularly connected to each other. The edge of the feeding plane 2 and the second plane & the second radiating region are substantially opposite each other including the feeding point and the first end point. Feed The feed line is electrically connected for transmission to the point. The distance between the feed point and a feed point needs to be smaller than the second end, the middle point of the middle point, and the point of the ~ point _ person point. Short-circuit element 6 M351461 Connect both the feed side and the ground element. The short-circuiting system is smaller than the short-circuiting element. The distance from the end point of the difficult-to-week-wei is less than or equal to the short-circuit component to the feeding two:: to the second.

The first radiating region 21 and the second radiating region 22 are substantially perpendicular to each other. The grounding element 30 serves as a grounding for the broadband antenna 1. The feed face 50 is a wide plane that is substantially perpendicular to the second region 52. The feed surface 50 has a feedthrough F, a first end point 51 and a second end point 52. The first end point 51 and the second end point 52 are located at the junction of the feed face 50 and the second radiating area 22. The feed point f is located at the edge of the feed face 50. The feed point F is electrically connected to a feed line (not shown) for transmitting an electrical signal. The feed line can be a cable such as HF Cable, but this creation is not limited to this. When the electrical signal is transmitted into the feed surface 7 M351461 50, since the feed surface 50 has a wide plane, the electrical signal can have a wider current transmission path when fed. The short-circuiting element 40 simultaneously connects the feed surface 50 and the ground element 30, so that the broadband antenna 10a has a better resonance effect. In the first embodiment of the present invention, the edge of the feed face 50' of the broadband antenna 10a is a substantially straight line boundary. It should be noted that in order to achieve the effect of the present creation, the present invention has a limitation on the shape relationship of the feeding surface 50 of the broadband antenna l〇a. The distance from the first end point 51 to the feed point F needs to be smaller than the distance from the second end point 52 to the feed point F. On the other hand, this creation also limits the position at which the shorting element 40 is connected to the feed surface 50. Wherein the distance from the second end point 52 of the feed face 50 to the shorting element 40 is less than the distance from the first end point 51 to the shorting element 40, and the distance from the second end point 52 to the shorting element 40 is less than or equal to the feed point The distance from F to the shorting element 40. In this way, the wideband antenna 10a can have a wider high frequency bandwidth. Fig. 2B shows the voltage standing wave ratio (VSWR) of the broadband antenna 10a at different frequencies. As is apparent from Fig. 2B, the VSWR of the wideband antenna l〇a is below 3 from the range of 2.5 GHz to 6 GHz. Therefore, the wideband antenna 10a has a function of transmitting a signal of about 2.5 GHz to 5.9 GHz. The wideband antenna 10a has a wider bandwidth than the antenna 90 of the prior art. Reference is next made to Figures 3A and 3B. Figure 3A is a perspective view of a second embodiment of the present inventive wideband antenna, and Figure 3B is shown in Figure 3A showing its VSWR at different frequencies. As shown in FIG. 3A, the shorting element 40 of the broadband antenna 10b is substantially at the center of the second end point 52 and the feed point F, that is, the distance between the shorting element 40 to the M351461 second end 52 is substantially equal to the shorting element 40. The distance to the feed point F. As is apparent in Fig. 3B, the wideband antenna 10b is operable in a range of approximately 2.5 GHz to 4.3 GHz, and the wideband antenna 1 Ob has a wider bandwidth than the antenna 90 of the prior art. Finally, please refer to FIG. 4 for a system block diagram of the electronic device of the present invention. The electronic device 60 of the present invention can be a notebook computer or a mobile device such as a GPS, but the creation is not limited thereto. As shown in FIG. 4, the electronic device 60 of the present invention includes a wideband antenna 10a and a wireless signal module 61. The electronic device 60 can use an RF cable (not shown) to feed the electrical signal to the broadband antenna 10a, wherein the broadband antenna 10a is connected to the wireless signal module 61 to process the broadband antenna by the wireless signal module 61. Signal of 10a, such as transmitting or receiving a signal. In this way, the electronic device 60 can receive or transmit wireless signals to other devices (not shown) through the broadband antenna 10a to achieve the purpose of wireless communication. It should be noted here that in one embodiment of the present invention, the wideband antenna 10a in the electronic device 61 can also be replaced by the wideband antenna 10b of the present invention, so that the purpose of the present invention can still be achieved. In summary, this creation, regardless of its purpose, means and efficacy, is showing its characteristics different from the well-known technology.
