[Prior Art] An antenna is used to transmit or receive radio waves to transmit or exchange radio signals. With the evolution of wireless communication technologies, wireless communication systems are operating at a wider frequency. For example, the LongTerm Evolution (LTE) system requires operating bands of 704 MHz to 960 MHz and 1710 MHz to 2700 MHz. In this case, how to effectively improve the antenna bandwidth and minimize the antenna size has become one of the goals of the industry. [New content] Therefore, the main purpose of this creation is to provide a broadband antenna for wireless communication systems with broadband requirements. The present invention discloses that a wide-width antenna includes a grounding portion electrically connected to a j-terminal radiating element 'substantially parallel to the grounding portion, including a first-radiation portion and a second light-emitting portion; The other end of the element is electrically connected to the other end of the grounding portion and electrically connected between the first radiating portion and the second light projecting portion; - matching the pie, setting; between the light σ 卩 and the grounding portion, a substantially quadrilateral; a feed element, and a 1 match between the 7C non-connected elements, through which the wire is electrically coupled to the matching element, and the first input signal; and a third radiation The light shots are roughly parallel. [Embodiment] The first picture of the first picture is the schematic diagram of the present invention - the wide-band antenna (1): the frequency y antenna 10 is suitable for a wireless communication system with broadband requirements, such as the LTE system, and is operable The dual frequency band includes a grounding portion, a paving secret, no = a member 1G4, a _matching read, a feeding component 108, and a third damming portion, and the grounding portion 100 is electrically connected to the ground end. To provide grounding. The radiation element (4) is substantially parallel to the ground portion (10) and includes a first light-emitting portion and a second portion 2102. Connecting element 1 (M is between the radiating element (1) 2 and the grounding part, ^ is electrically connected to the grounding point, 'the other end is electrically connected to the first light-emitting part,' and the second light-emitting part is between The matching component is disposed between the first radiating portion 1020 and the ±41GG and is substantially quadrangular. The feeding component (10) is disposed between the matching element and the connecting 7L member 1G4 for transmitting and receiving the signal through the matching component. The third ball portion 110 is electrically connected to the matching element 1〇6, and is composed of branches 11〇〇 and u〇2 substantially parallel to the first radiating portion 1020. In the broadband antenna ίο, the first-light portion The surface and the third radiating portion are used to control the low frequency operating frequency band, and the second radiating portion 1 22 controls the high frequency operating frequency band. In addition, in the first pattern, the matching read 1〇6 is surrounded by four metal frames. The quadrilateral is used to control the high and low frequency group anti-matching; _, the matching component] G6 and the first light-emitting part of the separation distance are related to the low-frequency operating band, the slightly grounding part of the interval M422774 distance is related to the high frequency Operating frequency band.

' ^And the left is the wideband antenna 1〇 is an embodiment of the creation, and the person skilled in the art can do different materials according to the information, and is not limited thereto. For example, the components of the broadband band can be determined in various ways, for example, Each domain element can be formed; the earth plate or the crucible can be fixed with an insulating material, etc. In addition, as in the field, the common knowledge of the age σ 'the day is related to the current path, therefore, the designer should For the operating frequency band, the size, material, etc. of the broadband antenna 10 are appropriately adjusted or the components are added to meet the requirements of the system. For example, please refer to FIG. 4, which is a creative embodiment. A wide-band antenna diagram. Compare Figure 4 and Figure It is known that the architecture and operation principle of the wideband antenna 4 is similar to that of the thin strip antenna 1G. Therefore, the same components are along the same rib. The wideband line is added to the fourth radiating portion 400 compared to the wideband antenna. The first radiating portion 110 and the grounding portion 8 (8) are electrically connected to the grounding portion 100 for increasing the high frequency operation bandwidth. Please refer to FIG. 5 and FIG. 6 , FIG. 5 and FIG. 6 . It is a schematic diagram of the voltage standing wave ratio and antenna efficiency of the wideband antenna 40 used in the LTE system. It can be seen from the fifth and sixth figures that the wideband antenna 4〇 can not only reach the wide frequency effect M422774, but also the south frequency partial phase. Compared with the wideband antenna 1 〇, it can be effectively increased. Thereby, the application range can be effectively improved. It should be noted that the shape of the first radiating portion 四 (4), the second light absorbing portion, and the third light absorbing portion 110 are not Limited to the example of FIG. 4 or FIG. 4, it may also include a plurality of bent or 疋 branches. Similarly, the fourth radiating portion 400 can also be appropriately changed. Further, in the first drawing or the fourth drawing, the matching member 106 is composed of four metal frames, but is not limited thereto. For example, please refer to FIG. 7, which is a schematic diagram of the present embodiment, a broadband antenna 70. Comparing Figure 7 with the figure, it can be seen that the structure and operation principle of the broadband antenna 7〇 is the same as that of the wide-ranging money 1G. The wide band antenna 70 differs from the wide band antenna 10 in that the matching element 700 of the wideband antenna 70 is formed of a quadrilateral metal piece, which also achieves high frequency and low frequency matching. On the other hand, the connecting member 104 is used to connect the radiating element 1〇2 and the ground portion _ 100 ', and its shape is not limited to the foregoing example. For example, please refer to FIG. 8. FIG. 8 is a schematic diagram of a wideband antenna 80 according to the creative embodiment. Comparing Fig. 8 and Fig. 7, it can be seen that the structure and operation principle of the wideband antenna 80 are similar to those of the wideband antenna, so that the same elements follow the same symbols. The wideband antenna 8G differs from the wideband antenna 7() in that the bending direction of one of the connecting elements 8 of the wideband antenna 80 is different from that of the wideband antenna % of the connecting element 104, which also achieves high frequency and low frequency matching.
