Description

Technical Field

[0001] This utility model relates to the field of communication equipment, and in particular to an antenna structure and electronic device. Background Technology

[0002] With the development and popularization of 5G technology, in order to balance the internal space utilization and functional requirements of communication equipment, the integrated antenna solution of GPS and WiFi is generally adopted. This means that the GPS antenna stubs and WiFi antenna stubs (including WiFi 2.4G and WiFi 5G bands) are integrated and share the substrate or part of the transmission path. For example, the existing patent publication number CN212648479U proposes a GPS and WiFi integrated antenna and mobile phone, which arranges the GPS antenna stubs, WiFi antenna stubs and the feeding unit in parallel and spaced along the length direction to save internal space and reduce the cost of the whole machine. This has become the mainstream design concept in the consumer electronics field.

[0003] However, the inventors discovered that the aforementioned integrated GPS and WiFi antenna has certain performance shortcomings. Specifically, to avoid large components such as the battery and motherboard at the bottom of the device, the GPS antenna stubs of existing integrated antennas are often placed at corners or side edges of the device. Since GPS signals are high-frequency electromagnetic waves with weak penetration and anti-blocking capabilities, the metal frame and other components of the device can directly block the GPS antennas located at corners or sides, resulting in severe attenuation of the upper hemisphere GPS signal and causing positioning drift, especially noticeable indoors or in complex environments. Furthermore, the initial GPS positioning (cold start) time typically takes several minutes, and even with AGPS assisted positioning technology, poor upper hemisphere signal reception affects positioning efficiency, making it difficult to meet users' real-time positioning needs. Finally, due to the close spacing between the GPS and WiFi antenna stubs, there is also the problem of mutual interference between frequency band signals.

[0004] Therefore, an antenna structure is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an antenna structure and electronic device that can effectively suppress mutual interference between GPS and WiFi frequency band signals, thereby ensuring signal stability.

[0006] To solve the above-mentioned technical problems, this utility model provides an antenna structure, including a coupling stub, a GPS antenna stub, and a WiFi antenna stub;

[0007] Both the GPS antenna stub and the WiFi antenna stub are connected to the coupling stub and are located on both sides of the coupling stub, respectively.

[0008] The GPS antenna stub has an extended protrusion, the end of which extends toward the middle region of the top surface of the electronic device body.

[0009] Furthermore, a first coupling gap is formed between the GPS antenna stub and the coupling stub, and the first coupling gap is L-shaped to form the extended protrusion.

[0010] Furthermore, the minimum width of the first coupling gap is 0.6mm-0.8mm.

[0011] Furthermore, a second coupling gap is formed between the WiFi antenna stub and the coupling stub, and the minimum width of the second coupling gap is 0.6mm-1.0mm.

[0012] Furthermore, the coupling stub is provided with a feed point and a feed location;

[0013] A third coupling gap is formed between the feed point and the feed location, and the minimum width of the third coupling gap is 0.4mm-0.6mm.

[0014] Furthermore, the length of the antenna structure is 20mm-25mm, and the width of the antenna structure is 8mm-12mm.

[0015] Furthermore, the antenna structure has a pre-fold line that matches the angle formed between the top surface and the surface of the electronic device body, for attaching the antenna structure to the electronic device body.

[0016] Furthermore, a first stress hole is provided within the coupling stub;

[0017] A second stress hole is formed between the coupling stub and the WiFi antenna stub;

[0018] The center point of the first stress hole and the center point of the second stress hole are both located within the trajectory of the pre-broken line.

[0019] Furthermore, the GPS antenna stub includes a first radiating stub, a second radiating stub, and a third radiating stub that are sequentially bent and connected along a direction away from the coupling stub;

[0020] The third radial branch is configured as an L-shaped structure, and the trajectory of the pre-broken line passes through the third radial branch.

[0021] On the other hand, the present invention also proposes an electronic device, including an electronic device body and the antenna structure described in the above embodiments;

[0022] The antenna structure is mounted on the electronic device body.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] By configuring coupling stubs, GPS antenna stubs, and WiFi antenna stubs, and connecting both the GPS and WiFi antenna stubs to the coupling stub, with the extended protruding end of the GPS antenna stub pointing towards the center of the top surface of the electronic device, the GPS antenna stub can avoid obstruction from components such as the corners and metal frames of the electronic device and concentrate the radiated energy towards the upper hemisphere. This enhances the receiving capability of the upper hemisphere GPS antenna stub, effectively solving the problems of GPS upper hemisphere signal attenuation and positioning drift. Furthermore, by positioning the GPS and WiFi antenna stubs on opposite sides of the coupling stub, they do not interfere with each other, effectively suppressing mutual interference between GPS and WiFi frequency band signals. This improves the upper hemisphere radiation efficiency of GPS and the success rate of positioning during cold starts, while also ensuring signal stability to meet the real-time positioning application needs of users.

Detailed Implementation

[0028] The antenna structure and electronic device of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0029] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0030] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0031] Example 1

[0032] like Figure 1 As shown in the figure, this utility model embodiment proposes an antenna structure, including a coupling stub 1, a GPS antenna stub 2, and a WiFi antenna stub 3.

[0033] The GPS antenna stub 2 and the WiFi antenna stub 3 are both connected to the coupling stub 1.

[0034] Furthermore, the GPS antenna stub 2 and the WiFi antenna stub 3 are located on both sides of the coupling stub 1, respectively. By placing the GPS antenna stub 2 and the WiFi antenna stub 3 on both sides of the coupling stub 1, they will not interfere with each other, thereby effectively suppressing the mutual interference between GPS and WiFi frequency band signals and achieving the purpose of ensuring signal stability.

[0035] In addition, the GPS antenna stub 2 has an extended protrusion, the end of which extends toward the middle area of ​​the top surface of the electronic device body 8, so that the GPS antenna stub 2 avoids being blocked by the metal frame and other components at the corner of the top surface of the electronic device body 8, and concentrates the radiated energy toward the upper hemisphere, thereby enhancing the receiving capability of the upper hemisphere GPS antenna stub 2 and effectively solving the problems of GPS upper hemisphere signal attenuation and positioning drift.

[0036] This device employs a coupling stub 1, a GPS antenna stub 2, and a WiFi antenna stub 3, with both the GPS antenna stub 2 and the WiFi antenna stub 3 connected to the coupling stub 1. The extended protruding end of the GPS antenna stub 2 extends towards the center of the top surface of the electronic device body 8. This allows the GPS antenna stub 2 to avoid obstruction from components such as the corner metal frame of the electronic device body 8 and concentrates the radiated energy towards the upper hemisphere, thus enhancing the receiving capability of the upper hemisphere GPS antenna stub 2 and effectively solving the problems of GPS upper hemisphere signal attenuation and positioning drift. Furthermore, by positioning the GPS antenna stub 2 and the WiFi antenna stub 3 on opposite sides of the coupling stub 1, they do not interfere with each other, effectively suppressing mutual interference between GPS and WiFi frequency band signals. This achieves the goal of improving the upper hemisphere radiation efficiency of GPS and the success rate of positioning during cold starts, while also ensuring signal stability to meet the real-time positioning application needs of users.

[0037] In this embodiment, a first coupling gap 4 is formed between the GPS antenna stub 2 and the coupling stub 1, and the first coupling gap 4 is L-shaped to form the extended protrusion. By forming an L-shaped first coupling gap 4 between the GPS antenna stub 2 and the coupling stub 1 to form the extended protrusion structure, the position and shape of the extended protrusion meet the signal reception requirements, ensuring the GPS antenna function is realized while also concentrating the radiated energy towards the upper hemisphere.

[0038] The minimum width of the first coupling gap 4 is 0.6mm-0.8mm, preferably 0.7mm, in order to balance the coupling strength between the GPS antenna stub 2 and the coupling stub 1, avoid affecting signal transmission due to the first coupling gap 4 being too wide or too narrow, and ensure the GPS signal reception efficiency.

[0039] In other embodiments, the WiFi antenna stub 3 and the coupling stub 1 are further defined to improve signal reception efficiency.

[0040] Specifically, a second coupling gap 5 is formed between the WiFi antenna stub 3 and the coupling stub 1, and the minimum width of the second coupling gap 5 is 0.6mm-1.0mm, preferably 0.7mm, 0.8mm, or 0.9mm. That is, the second coupling gap 5 isolates the WiFi antenna stub 3 from the coupling stub 1, and by limiting the minimum width of the second coupling gap 5, both WiFi signal transmission and interference with GPS signals can be guaranteed.

[0041] In addition, the coupling stub 1 is provided with a feed point 12 and a feed point 11, which are used to provide power and signal input channels and grounding protection for the antenna structure, ensuring that the entire antenna system can receive and transmit signals normally. This is the basic configuration for the antenna to realize its function.

[0042] A third coupling gap 6 is formed between the feed point 12 and the feed point 11, and the minimum width of the third coupling gap 6 is 0.4mm-0.6mm. By limiting the size of the third coupling gap 6, the electrical isolation between the feed point 12 and the feed point 11 is controlled, signal short circuits or interference are avoided, feed stability is ensured, and thus the overall signal transmission quality of the antenna is maintained.

[0043] In a further embodiment, the antenna structure has a length of 20mm-25mm and a width of 8mm-12mm. This allows the antenna structure to fit within the limited space of electronic devices, meeting signal performance requirements while also satisfying the miniaturization requirements of consumer electronics components, thus improving practicality.

[0044] In other embodiments, the antenna structure has a pre-fold line 7 that matches the angle formed between the top surface and the surface of the electronic device body 8, for attaching the antenna structure to the electronic device body 8. This allows the antenna structure to fit tightly against the angle of the electronic device body 8 under the action of the pre-fold line 7, improving installation stability and making full use of device space, avoiding signal interference or additional space occupation due to loose installation.

[0045] It should be noted that a first stress hole 13 is provided in the coupling stub 1, and a second stress hole 14 is formed between the coupling stub 1 and the WiFi antenna stub 3.

[0046] The center point of the first stress hole 13 and the center point of the second stress hole 14 are both located within the trajectory of the pre-folded line 7.

[0047] By setting the first stress hole 13 and the second stress hole 14, the stress generated in the antenna structure during installation and use is dispersed, preventing structural deformation or damage due to stress concentration, and improving the mechanical stability and service life of the antenna structure.

[0048] In a further embodiment, the GPS antenna stub 2 includes a first radiating stub 21, a second radiating stub 22, and a third radiating stub 23 that are sequentially bent and connected along a direction away from the coupling stub 1.

[0049] The third radiating branch 23 is configured as an L-shaped structure, and the trajectory of the pre-folded line 7 passes through the third radiating branch 23. That is, most of the third radiating branch 23 is located on the top surface of the electronic device body 8, and part of it is located on the surface of the electronic device body 8. This makes the GPS antenna branch 2 wrapped around the corner of the electronic device body 8 during installation, thus effectively improving the stability of the GPS antenna branch 2 after installation.

[0050] Example 2

[0051] like Figure 2 As shown, this embodiment proposes an electronic device based on embodiment one, including an electronic device body 8 and the antenna structure described in the above embodiment.

[0052] The antenna structure is disposed on the electronic device body 8.

[0053] By setting up an electronic device with the antenna structure described in Embodiment 1, the problem of GPS and WiFi integrated antennas being blocked by components due to their placement at corners or sides of the device, leading to GPS upper hemisphere signal attenuation and positioning drift, is effectively solved. It can also effectively suppress mutual interference between GPS and WiFi frequency band signals, while improving the radiation efficiency of the GPS upper hemisphere and the success rate of positioning during cold starts, thereby ensuring signal stability to meet the real-time positioning application needs of users.

[0054] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
