In the current trend of bribery to high operating frequency and high frequency, communication cannot be provided. Wei Weicheng, Wei Wei, Lai Wei, Wei Wei, and so on, have limited their application scope. Therefore, it is necessary to propose a new grounding method to improve the conventional air-based microstrip antenna! Q in Gao Lai's bandwidth and enhanced light shooting characteristics ’and can provide good shooting field type. [New content] ^ Ling is, in the above creative background, "antenna" in wireless communication products, important position, and has a great impact on the performance of wireless communication, so the design of the antenna_low Cost, high efficiency, fresh implementation and so on. Bai Zhizhi's air-based microstrip antenna is not easy to obtain good high-frequency and gain radiation characteristics at the same time as a towel, so it cannot provide a wider application range. The main purpose of this creation is to provide an L-shaped grounding antenna, especially a grounding element with an L-shaped appearance to "—the continuous two surfaces of a microstrip antenna without light-emitting wires, so that the conventional air-based The microstrip antenna can obtain the radiation characteristics of high frequency bandwidth and high gain at the same time when operating at high frequency (for example: 5GHz). The L-shaped ground antenna of this creation is simple in construction and can be made using the inexpensive FR 4 fiber-breaking material. Significantly reduce production costs and have high application value in the industry. At the same time, 'This microstrip antenna can be made of FR 4 glass fiber material which is cheap, and it can also reduce the production cost by a large amount. According to the purpose mentioned above' The creation provides an L-shaped ground antenna. The L-shaped ground antenna of this creation includes at least a microstrip antenna, where the microstrip antenna includes at least a PCB substrate and a radiation conductor, where the radiation conductor is formed only on one of the radiation surfaces of the substrate, L-shaped grounding element, wherein the L-shaped grounding element surrounds two continuous surfaces of the microstrip antenna without radiating wires, and the L-shaped grounding element It includes at least a vertical grounding element and a horizontal grounding element; and a feeding pin contact point of a radiating wire connected to a spokesperson through a direct ground element and an antenna substrate (for example, air). [Embodiment] It is convenient and expensive. The reviewing committee can further deepen the structure, use and characteristics of this creation, and have a clear and detailed knowledge and understanding. The creator provides a better example, with detailed illustrations such as +: Yuxian Please Participate 2 As shown in the figure, the L-shaped ground antenna of the present invention is preferably implemented to improve the complementary characteristics of the conventional microstrip antenna at high frequency operation. The L-shaped ground antenna of this creation lacks the vertical surface i Q 4 On the ground plane 105, an L-shaped grounding element 2 Q composed of a vertical grounding element 2! Q and a horizontal grounding element 2 2 0 surrounds two consecutive surfaces of the upper surface of the microstrip antenna, and the grounding plane is horizontal. The tree 2 2 Q is located on the ground plane 丄 05. There is a vertical distance 2 7 0 ′ between the p CB substrate 〇〇 and the horizontal grounding element 2 2 Q and a horizontal distance 2 6 between the vertical grounding element 21 and 〇. Microstrip antenna 1 Q and There is an antenna substrate 2 5 0 between the L-shaped grounding forest 2 and the antenna substrate 2 5 0 may be a medium having a dielectric constant close to air, as described above. The L-shaped plastic grounding element 20 surrounds the microstrip antenna 10. After two consecutive surfaces of the non-radiating surface, the feeding pin 2 40 passes through the vertical grounding element 2 丄 〇 and the antenna substrate 2 50 and is connected to the feeding pin contact point 13 of the radiating wire. Feeding pin 2 4 In addition to being used for transmitting signals, 0 also has the function of supporting the pc Β substrate 10 0. If the structure of the L-shaped ground antenna of this creation is not strong enough, this creation can also use at least one supporting element 2 3 0 to connect to the L-type ground The component 20 and the microstrip antenna 10 increase the structural stability of the L-shaped ground antenna. In addition, the size of the flat space of the L-shaped ground antenna of 26 ° will affect the size of the resonance frequency, and the vertical rhyme distance of 27 ° will affect the radiation pattern of the antenna. The L-shaped grounding element 20 may be made of, for example, copper, and the thickness of the vertical grounding element 21 and the horizontal grounding element 22 may be determined according to actual needs, and may be a plate-like element with a smaller thickness or a larger thickness. Blocky elements. In addition, the material of the substrate 丄 〇 〇 can use the inexpensive R 4 glass fiber material, and the radiation wire is a metal radiation. _Excerpt—Tactical supplement, Benwon U-shaped ground antenna can obtain satisfactory radiation characteristics at the south frequency (for example: 5GHz). In addition, this creation can also use radiating wires of different shapes, so that M241808 k at high frequencies provides good reception and radiation field patterns, and antenna gain. Please refer to FIG. 4. FIG. 4 is a schematic diagram illustrating a structure of a round wire on a radiating surface of an L-shaped ground antenna according to another embodiment of the present invention. In addition to the mouth-shaped and gate-shaped shapes shown in Figure 3, the "first-radius lead 3 2 0 can also be a -winding arc type, and the second radiating lead 3 2 4 can also be a -down-string arc type, and then The connecting radiation wire 3 2 2 is further connected to the center positions of the first radiation wire 3 2 Q and the second radiation wire 3 2 4.
