[0018] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0020] The antenna structure 1 of this application includes a camera decorative element 11 and a feed. The camera decorative element 11 is a metal component and includes multiple sequentially connected frame segments 112, forming multiple folded edges 113. Adjacent frame segments 112 extend in different directions to form folded edges 113 at their connection points. The camera decorative element 11 has at least one first upper frame point 114 for connecting the feed and multiple second upper frame points 115 for connecting metal ribs. The first and second upper frame points 114 are arranged at circumferential intervals along the camera decorative element 11, with the first upper frame point 114 located at the folded edge 113. Two adjacent frame segments 112 include a first frame segment and a second frame segment. The branch between the metal rib of the first frame segment and the end near the second frame segment is a first radiator, and the branch between the metal rib of the second frame segment and the end near the first frame segment is a second radiator. The feed is electrically connected to point 114 on the first upper frame, and excites the first radiator and the second radiator to radiate antenna signals. The radiation direction of the first radiator is different from that of the second radiator.

[0021] The antenna structure 1 of this application cleverly utilizes the folded edge 113 and frame segment 112 of the camera decorative piece 11 to construct a radiator, enabling the antenna structure 1 to radiate antenna signals simultaneously in the first and second radiators. This allows the antenna signal to radiate in two different directions, effectively improving the omnidirectionality of the antenna and solving the problem of single antenna radiation direction and limited signal coverage in traditional DECO (i.e., the metal decorative piece of the camera). This ensures that the antenna structure 1 can receive or transmit signals from different directions. Furthermore, the antenna structure 1 of this application has multiple upper frame points designed on its periphery, which, combined with the design of the metal ribs, can disrupt the current mode of the camera decorative piece 11 itself, thereby reducing the coupling influence of the camera decorative piece 11 on antennas in other locations. It also provides a stable path for current conduction in the radiator, ensuring the stability and reliability of the antenna signal radiation.

[0022] In an optional embodiment, when the power supply is in operation, the radiation direction of the main lobe of the first radiator is perpendicular to the first frame segment. The radiation direction of the main lobe of the second radiator is perpendicular to the second frame segment.

[0023] The antenna structure 1 of this application, through the design of the feed and side frame segments 112, makes the radiation direction of the main lobe of the first radiator perpendicular to the first frame segment, and the radiation direction of the main lobe of the second radiator perpendicular to the second frame segment. This design can concentrate the radiated energy of the antenna signal to propagate more concentratedly along the direction perpendicular to each frame segment 112, thereby obtaining a stronger signal strength in that direction, further optimizing the radiation performance and omnidirectionality of the antenna.

[0024] In an optional embodiment, the extension directions of the first and second border segments are perpendicular, and the radiation direction of the main lobe of the first radiator is perpendicular to the radiation direction of the main lobe of the second radiator.

[0025] In this embodiment, the antenna structure 1 is designed so that the first frame segment is perpendicular to the second frame segment, thereby making the main lobe radiation directions of the two radiators perpendicular as well. This achieves strong signal coverage of the antenna in two mutually perpendicular directions, greatly enhancing the omnidirectionality of the antenna. This improves the signal reception or transmission capabilities of the antenna structure 1 in both horizontal and vertical directions, helps to reduce antenna signal blind spots, and improves the communication quality of the antenna structure 1 in complex usage scenarios (such as when the device is in different holding postures or placement angles, such as horizontal or vertical screens).

[0026] It should be noted that the antenna structure 1 can be adjusted accordingly based on different camera designs and user needs. For example, in an embodiment where the camera decorative piece 11 is an equilateral triangle, the antenna structure 1 can radiate using two adjacent frame segments 112 facing the top and sides; in an embodiment where the camera decorative piece 11 is similar to a racetrack shape, it can radiate using the arched frame segment 112 at the top and the side frame segments 112, and so on. In the embodiment provided in this application, a rectangular camera decorative piece 11 is used as an example, with antenna radiation formed at the top and sides of the camera decorative piece 11. Therefore, this application does not impose any limitations on this.

[0027] In an optional embodiment, the camera trim 11 further includes a mounting area 116 for mounting a camera, with a first upper frame point 114 located outside the mounting area 116. At least one power supply is provided, with each power supply electrically connected to one first upper frame point 114.

[0028] In practical application scenarios, such as Figure 1As shown, the mounting area 116 of the camera decorative piece 11 is close to one of the folded edges 113. Therefore, the first upper frame point 114 is not designed at the position of the folded edge 113, so as to avoid coupling and interference between the antenna and the camera when the antenna is working, so as to ensure the stability of the radiation signal of the antenna structure 1, and at the same time, to ensure the image of the camera is clear and the function is stable.

[0029] Specifically, in an optional embodiment, the camera decorative element 11 is rectangular, and the plurality of frame segments 112 include a first side frame segment 1121, a top frame segment 1122, a second side frame segment 1123, and a bottom frame segment 1124 connected in sequence. The connection position of the first side frame segment 1121 and the top frame segment 1122 forms a first folded edge 1131, the connection position of the second side frame segment 1123 and the top frame segment 1122 forms a second folded edge 1132, the connection position of the second side frame segment 1123 and the bottom frame segment 1124 forms a third folded edge 1133, and the connection position of the bottom frame segment 1124 and the first side frame segment 1121 forms a fourth folded edge 1134. The number of first upper frame points 114 is one, and it is correspondingly disposed on the first folded edge 1131. The power supply includes a first power supply, which is electrically connected to the first upper frame point 114.

[0030] like Figure 1 As shown, the antenna structure 1 of this application is based on a rectangular camera decorative piece 11. A first upper frame point 114 and a first feed (shown as a red dot in the figure) are set using a first folded edge 1131. Radiation is generated on the first side frame segment 1121 and the top frame segment 1122, thereby expanding the signal coverage area of ​​the antenna structure 1 and improving the overall radiation power and omnidirectionality of the antenna. Figure 2 As shown, this design enables antenna structure 1 to have strong signal coverage in both directions perpendicular to the first side frame segment 1121 and the top frame segment 1122, greatly enhancing the omnidirectionality of the antenna. At the same time, this structure is simple and easy to manufacture and assemble.

[0031] In optional embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the antenna structure 1 also includes a middle frame 12, which surrounds the periphery of the camera decorative element 11 and forms a cavity between the middle frame 12 and the camera decorative element 11. When the feed is in operation, the first radiator and the second radiator respectively generate cavity mode radiation within the cavity, with the current direction as shown... Figure 3 The blue arrow in the middle and Figure 4 , Figure 5 As indicated by the red arrow in the middle.

[0032] The antenna structure 1 of this application utilizes the cavity between the mid-frame 12 and the camera decorative element 11 to provide space for cavity mode radiation of the radiator. This multi-faceted structure achieves a three-dimensional electromagnetic field distribution, thereby improving the uniformity of signal coverage and resulting in higher radiation efficiency and a wider radiation direction for the antenna signal, thus further enhancing the antenna's radiation performance. Simultaneously, utilizing cavity mode radiation allows the antenna to achieve stronger signal radiation within a limited space, reducing random signal scattering, improving signal directionality and intensity, and ultimately enhancing the communication quality of electronic devices.

[0033] like Figure 6 The diagram shows the reflection coefficient S11 curve of antenna structure 1. Taking the GPS L5 band as an example, referring to labels 1 and 2 in the figure, the input matching effect of antenna structure 1 of this application (shown by the orange line in the figure) is significantly better than that of traditional antenna designs with a single radiation direction (shown by the blue line in the figure) at around 1.17 GHz. Figure 7 The figure shows the radiation efficiency of antenna structure 1. Referring to reference numerals 1 and 2 in the figure, the radiation efficiency curve (shown by the purple solid line in the figure) and the total efficiency curve (shown by the brown solid line in the figure) of antenna structure 1 of this application are better than the radiation efficiency (shown by the green dashed line in the figure) and the total efficiency (shown by the blue dashed line in the figure) of traditional antenna design at around 1.17 GHz.

[0034] In another alternative embodiment, such as Figure 8 As shown, the camera mounting area 116 is located near the bottom of the camera trim 11. Therefore, there are two first upper frame points 114, respectively located on the first folded edge 1131 and the second folded edge 1132. The power supply includes a first power supply and a second power supply, which are electrically connected to the two first upper frame points 114 respectively.

[0035] This design allows the two feeds to excite the corresponding radiators, enabling the antenna to radiate on the first side frame segment 1121, the top frame segment 1122, and the second side frame segment 1123 respectively. Furthermore, the radiation direction of the main lobe of the antenna signal is directed towards the side and top of the camera decorative piece 11, thereby further expanding the antenna's radiation coverage, improving the overall radiation power and omnidirectionality of the antenna, and making the antenna structure 1 more sensitive to signal reception in multiple directions and more stable in communication.

[0036] Similarly, as Figure 9 As shown, in the embodiment where the camera mounting area 116 is near the fourth fold 1134 of the camera decorative piece 11, there are three first upper frame points 114, which are respectively disposed on the first fold 1131, the second fold 1132, and the third fold 1133. The power supply includes a first power supply, a second power supply, and a third power supply, and is electrically connected to the three first upper frame points 114 respectively.

[0037] This design can further enhance the omnidirectionality and comprehensiveness of the antenna within a limited design area, ensuring good communication performance and reducing signal attenuation and interruption even when the device is in a relatively complex environment.

[0038] Of course, such as Figure 10 As shown, in an embodiment where the camera mounting area 116 is located at the center of the camera decorative piece 11, the number of first upper frame points 114 can also be designed to be four, respectively set on the first folded edge 1131, the second folded edge 1132, the third folded edge 1133 and the fourth folded edge 1134; the power supply includes the first power supply, the second power supply, the third power supply and the fourth power supply, and is electrically connected to the four first upper frame points 114 respectively.

[0039] This multi-feed, multi-radiator design can further enhance the omnidirectionality and comprehensive signal coverage of the antenna, enabling the antenna structure 1 to obtain strong radiated signals in all directions of the camera decoration 11, expanding the antenna coverage range and ensuring better communication performance.

[0040] This application also provides an electronic device including the antenna structure 1 as described above.

[0041] The electronic device of this application, by adopting the antenna structure 1, can achieve a multi-directional antenna design with the help of the camera decorative piece 11, improving the omnidirectionality of antenna radiation and thus enhancing the communication performance of the electronic device. It can ensure a stable and reliable signal connection whether indoors, outdoors, or during movement. Furthermore, this design does not occupy the space of the original mid-frame 12 of the electronic device, saving design space and reducing production costs. It also ensures strong isolation between the antenna mounted on the camera decorative piece 11 and the antenna mounted on the mid-frame 12, reducing the impact of the camera decorative piece 11 on the surrounding mid-frame 12 antennas and improving the overall radiation efficiency of the electronic device.

[0042] It should be noted that the technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
