It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the explanation of the embodiments of this utility model. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different proportions may be used in different drawings to illustrate different aspects.

[0021] With the development of smart technology, smartphones are placing increasingly higher demands on antenna performance. To meet this need, this invention proposes a novel high-efficiency antenna design. Figure 1 The schematic diagram shows the main components and layout of the antenna. Through its carefully designed structure and wiring, this antenna achieves efficient radiation over a wide frequency band. This invention provides a high-efficiency antenna that can be applied to various types of mobile terminal devices, such as commonly used smartphones, tablets, and laptops.

[0022] Specifically, the high-efficiency antenna comprises a feeding point 10, a grounding point 20, a first radiating branch 30, a second radiating branch 40, a third radiating branch 50, and a fourth radiating branch 60, the second radiating branch 40 is electrically connected with the feeding point 10, and the fourth radiating branch 60 is electrically connected with the grounding point 20; a first gap 70 is formed between the second radiating branch 40 and the third radiating branch 50, a second gap 80 is formed between the second radiating branch 40 and the fourth radiating branch 60, and a third gap 90 is formed between the third radiating branch 50 and the fourth radiating branch 60, and the first gap 70, the second gap 80 and the third gap 90 are in communication with each other.

[0023] In this way, the high-efficiency antenna effectively improves the working efficiency and bandwidth coverage range of the antenna by optimizing the antenna structure and the layout of the lines. Compared with the traditional inverted F, low-frequency package high-frequency and line form with added parasitic, the antenna design proposed by the utility model can realize high-efficiency radiation in a wider frequency band without sacrificing the efficiency of individual frequency bands, thereby meeting the high requirements of 5G communication technology on the performance of the antenna.

[0024] Further, the high-efficiency antenna further comprises a substrate, and the first radiating branch 30, the second radiating branch 40, the third radiating branch 50 and the fourth radiating branch 60 are all arranged on the substrate. In this way, the substrate serves as the basis for supporting and fixing the radiating branches, ensuring the stability and overall performance of the antenna structure. By reasonably designing the material, size and layout of the substrate, the radiation efficiency and bandwidth characteristics of the antenna can be further optimized. In addition, the selection of the substrate also needs to consider the matching with the working frequency of the antenna to reduce signal loss and improve transmission quality. In specific implementation, the surface of the substrate can also be specially treated to enhance its adhesion to the radiating branches and electrical performance.

[0025] Preferably, the first gap 70, the second gap 80 and the third gap 90 are in communication with each other to form a Y-shaped gap.

Through the mutual communication of the gaps, the propagation path of the electromagnetic wave can be more effectively guided, and unnecessary energy loss can be reduced. At the same time, the Y-shaped gap structure can also increase the bandwidth of the antenna to a certain extent, so that it can better adapt to the signal transmission requirements of different frequencies.

The vertical arrangement of the second radiation branch 40 and the fourth radiation branch 60 helps to guide electromagnetic waves in different directions and enhances the directivity of the antenna. At the same time, the vertical arrangement of the fourth radiation branch 60 and the third radiation branch 50 further expands the radiation range of the antenna, so that the antenna can better cover the target area. The parallel arrangement of the second radiation branch 40 and the third radiation branch 50 helps to maintain the stability of the antenna structure and reduce performance fluctuations caused by external environmental changes. The first radiation branch 30 is located at the connection position of the second radiation branch 40 and the fourth radiation branch 60 and extends in the opposite direction of the second radiation branch 40. This design not only optimizes the overall structure of the antenna, but also further enhances the radiation efficiency and directivity of the antenna. By reasonably arranging the positions and directions of the radiation branches, the antenna can ensure transmission quality while achieving wider signal coverage.
