• M329255 捌, new description [New technical field] This creation is about an antenna, especially about the creation of a broadband antenna with a town entrance. • [Prior Art] With the development of wireless communication technology, many electronic products that provide wireless communication functions, such as mobile phones and notebook computers, have been widely used in the market to transmit information. With the advancement of wireless 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 WWAN (Wireless Wide Area Network) antennas have become very popular and occupy an important position. Therefore, it is a built-in antenna for various wireless communication products. In the prior art, the operating frequency required for WWAN antennas is typically in the range of 824 to 960 MHz and 1710 to 2170 MHz. However, with the advancement of technology, the bandwidth of antennas in the prior art is no longer sufficient. Today's antennas are required to have a wider bandwidth, including, for example, 1575MHz for Global Positioning System (GPS) and handheld digital video broadcasting (Digital Video)

Broadcasting-Handheld, DVB, H) 1627MHz and other frequencies 0 In order to make these electronic products have wireless communication functions and to comply with the transmission of each M329255 frequency band, the prior art has disclosed an antenna in which electromagnetic waves can be set in these electronic products. The antenna 90 disclosed in the prior art is disclosed in U.S. Patent No. 6,861,986. The prior art antenna 90 has a radiating element 91, a connecting element 92 and a grounding element 93. The connecting member 92 has a first end 921 and a second end 922; and the first end 921 of the connecting member 92 is connected to the radiating element 91, and the second end 922 is connected to the grounding member 93. Next, please refer to FIG. 1B for the voltage standing wave ratio (VSWR) of the antenna 90 of FIG. 1A at different frequencies. As can be seen from Fig. 1B, the antenna 90 can only be transmitted over a range of frequencies of about 2.5 GHz and about 5 GHz. Therefore, the antenna 90 in the prior art does not meet the bandwidth requirements of today's WWAN antennas or other wideband antennas. Therefore, a new wideband antenna needs to be created to solve the problems of the prior art. [New content] The main purpose of this creation is to provide an antenna with a wide-band effect. To achieve the above object, the broadband antenna of the first embodiment of the present invention includes a radiating element, a grounding element, a short-circuiting element, and a feed surface. The radiating element includes a first radiating region and a second radiating region, and the first radiating region and the second radiating region are perpendicularly connected to each other. The shorting element simultaneously connects the first radiating region of the radiating element with the grounding element. The feed face is a broad face that is perpendicular to the second radiating region. Edge pockets for feed faces • M329255 includes feed points, first and second endpoints. The feed point is electrically connected to a feed line for transmitting an electrical signal. The distance from the first endpoint to the feed point needs to be less than the distance from the second endpoint to the feed point.

The radiating element 20 includes a first radiating region 21 and a second radiating region 22 for transmitting wireless communication signals. The first radiating region 21 and the second radiating region 22 are perpendicularly connected to each other. The grounding element 30 serves as a ground for the multi-frequency antenna 10a. The shorting element 40 simultaneously connects the first radiating region 21 of the radiating element 20 with the grounding member 30, so that the broadband antenna 10a has a better resonance effect.

The feed line can be a cable such as RF Cable, but this creation is not limited to this. When the electrical signal is transmitted into the feed surface 50a, since the feed surface 50a has a wide plane, the electrical signal can have a wider current transmission path when fed. In the present embodiment, the edge of the feeding face 50a of the wideband antenna 10a is a boundary of a straight line. It should be noted that this creation has a limitation on the shape relationship of the feeding surface 50a of the broadband antenna 10a.

And the distance from the second end point 52b to the shorting element 40 is also smaller than the distance from the first end point 51b to the shorting element 40, and the distance from the shorting element 40 to the second end point 52b is also less than or equal to the shorting element 40 to the feeding point. The distance of F. In this way, the broadband antenna 10c can also achieve the effect of wide frequency. M329255 It should be noted that the boundary of the feed surface 50a of the present creation is not limited to the shape of the ladder shape in FIG. 2A, and may be a shape of a boundary such as a triangle or a circular arc shape, for example, FIG. 5A The illustrated embodiment. Figure 5A is a perspective view of a fourth embodiment of the present inventive broadband antenna. In Fig. 5A, the boundary of the feeding surface 50c of the broadband antenna 100d is a circular arc type boundary. It is to be noted that the distance relationship between the feed point F of the broadband antenna l〇d to the first end point 51c and the first two end point 52c is also limited. The distance from the first end point 51c to the feed point F needs to be less than the distance from the second end point 52c to the feed point F. I and likewise, the distance from the second end point 52c to the shorting element 40 is less than the distance from the first end point 51c to the shorting element 40, and the distance from the shorting element 40 to the second end point 52c is also less than or equal to the shorting element 40 The distance to feed the point F. Please refer to FIG. 5B for showing the VSWR at different frequencies according to FIG. 5A. As can be seen from Fig. 5B, the feeding surface 50c of the arc-shaped boundary can also have the effect of wide-band antenna l〇d. The shape of the feed face can also be as shown in Fig. 6A, which is a perspective view of a fifth embodiment of the present wideband antenna. The wideband antenna 10e has a feed surface 50d.

The function of the parasitic element 31 is such that the bandwidth of the wideband antenna 10h at the low frequency can be shifted to a lower frequency. As a result, the VSWR of the broadband antenna 10h at different frequencies is as shown in Fig. 9B, and Fig. 9B shows the VSWR at different frequencies according to Fig. 9A. As can be clearly seen in Fig. 9B, the wideband: Qinliang l〇h can function between frequencies of about 1.6 GHz to 2.2 GHz, such as 11 • M329255, which can meet the bandwidth requirements of WWAN antennas.

The field diagram of the broadband antenna 1 〇 j in the horizontal plane is as shown in Fig. 11C, and Fig. 11A shows its field diagram in the horizontal plane in accordance with Fig. 11A. As can be seen from the field diagram of Fig. 11C, the wideband antenna 10j is also an omnidirectional antenna. Finally, please refer to FIG. 12 for a system block diagram of the electronic device of the present invention. The electronic device 60 can be a notebook computer or a mobile device such as a GPS device, and the creation is not limited thereto. As shown in FIG. 12, the present invention can be used to feed the broadband antenna l〇a (or the wideband antenna 1〇b to the broadband antenna l〇j) to the wireless signal module 61 by using the RFCable.
