Detailed Implementation

[0051] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0052] As described in the background section, with the continuous development of modern mobile communication devices, users have put forward higher requirements for the thinness, performance and multi-functionality of electronic devices. This has led to the continuous compression of the installation space inside electronic devices for antenna placement, thereby affecting the performance of the antenna.

[0053] Taking laptops and similar devices as examples, these devices not only need powerful computing capabilities but also support high-speed wireless network connections, such as WLAN (Wireless Local Area Network). Driven by the IEEE 802.11 series of standards, WLAN technology has become an indispensable function of modern mobile devices. However, with the continuous miniaturization of devices and the popularity of metal casing designs, antenna design faces numerous challenges. Traditional antenna designs typically place the radiator structure at the edge or inside the device, but this approach has many problems. For example, the metal casing can shield the radiation performance of the radiator structure, leading to signal attenuation and reduced coverage. Furthermore, the size and location of the radiator structure are strictly limited by the internal space of the device, making it difficult to achieve ideal radiation performance.

[0054] To address these issues, one design solution is to integrate the radiator structure with the laptop's hinge assembly. Because the radiator structure is located outside the display and keyboard bodies, the display and keyboard bodies can each utilize all-metal casings, saving internal installation space and resulting in a better user experience.

[0055] Since the radiator structure of an antenna typically requires a wavelength corresponding to one-quarter of the resonant frequency to achieve resonance, designing the required resonant frequency places certain demands on the dimensions of the radiator structure. Therefore, for designs integrating the radiator structure onto a hinge assembly, the length of the hinge housing to accommodate the radiator structure is crucial. A longer hinge housing provides more space for arranging the radiator structure, making it easier to design the radiator structure for the required resonant frequency. However, this increases the length of the hinge housing, which is detrimental to Industrial Design (ID) of electronic devices—the overall planning of the electronic device's aesthetics, form, structure, human-computer interaction, and user experience. Specifically, in designs integrating the radiator structure onto a hinge assembly, the core goal of ID design is to achieve product thinness, visual simplicity, and form harmony.

[0056] In conventional designs, integrating the radiator structure onto the hinge assembly significantly increases the length of the hinge housing. Therefore, minimizing the length of the hinge housing while ensuring antenna performance is a pressing issue that needs to be addressed.

[0057] In view of this, embodiments of this application provide an electronic device, including a first body, a second body, and a rotating shaft assembly connected between the first body and the second body to enable relative rotation between the two;

[0058] An antenna assembly, comprising a feed source and a first radiator structure electrically connected to the feed source; the first radiator structure is disposed on a rotating shaft assembly.

[0059] The electronic device also includes a pivot housing that is at least partially fitted onto the pivot assembly to shield it, a first radiator structure located within the receiving space of the pivot housing, and an antenna assembly that includes a second radiator structure disposed on the surface of the pivot housing, the second radiator structure and the first radiator structure being capable of being coupled and fed.

[0060] When the antenna assembly is in operation, the feed signal fed into the first radiator structure from the feed source can be coupled to the second radiator structure, so that the antenna assembly can transmit and receive wireless signals through the first radiator structure and the second radiator structure.

[0061] In the electronic device provided in this application embodiment, the radiator structure and the pivot assembly of the antenna assembly are integrated, so that the radiator structure does not need to occupy the internal installation space of the first body and the second body. This not only facilitates the miniaturization and thinning design of the electronic device, but also avoids interference from the electronic components inside the electronic device to the radiator structure, and also allows the radiator structure to have a more sufficient clearance environment, thereby improving the performance of the antenna assembly.

[0062] Furthermore, the first radiator structure of the antenna assembly is placed within the housing space of the pivot housing. The existing housing space of the pivot housing can be used to install the first radiator structure, while the second radiator structure of the antenna assembly is placed on the surface of the pivot housing. This allows for coupling and feeding between the first and second radiator structures to meet the required resonant frequency. In this way, the impedance matching of the antenna assembly can be optimized through the second radiator structure. Without sacrificing antenna assembly performance, the length of the first radiator structure can be significantly shortened, thereby reducing the space requirements of the first radiator structure on the pivot housing and reducing the overall length of the pivot housing, facilitating the ID design of electronic devices.

[0063] It should be noted that, in this application embodiment, the electronic device is not limited to a laptop computer, but can also be an electronic device with a hinge assembly, such as a foldable phone, a foldable tablet computer, or a smart wearable device. This application embodiment does not limit the type of electronic device.

[0064] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] refer to Figures 1-4 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows the structure of the hinge assembly in the electronic device. Figure 3 for Figure 2 The diagram shows the installation method of the first radiator structure in the rotating shaft assembly. Figure 4 for Figure 2 A schematic diagram of the shaft housing in the shaft assembly shown.

[0066] like Figures 1-4 As shown, the electronic device includes: a first body 101, a second body 102, and a rotating shaft assembly 103 connecting the first body 101 and the second body 102 to achieve relative rotation between them; an antenna assembly, the antenna assembly including a feed ( Figures 1-4 The feed source is not shown in the figure, and a first radiator structure 104 electrically connected to the feed source is also shown.

[0067] The electronic device also includes a hinge housing 106, which is at least partially fitted onto the hinge assembly 103 to shield it. A first radiator structure 104 is located within the receiving space of the hinge housing 106. The antenna assembly also includes a second radiator structure 105 disposed on the surface of the hinge housing 106. The second radiator structure 105 and the first radiator structure 104 are coupled and fed together. When the antenna assembly is in operation, the feed signal fed into the first radiator structure 104 from the feed source can be coupled to the second radiator structure 105, enabling the antenna assembly to transmit and receive wireless signals through the first radiator structure 104 and the second radiator structure 105.

[0068] The second radiator structure 105 can be coupled to the first radiator structure 104 to adjust the impedance of the antenna assembly, thereby improving the performance of the antenna assembly with a smaller rotating housing 106. The length of the rotating housing 106 is its dimension in the first direction X. The rotating assembly 103 extends along the first direction X, i.e., the first direction X is the length direction of the rotating assembly 103, and the first body 101 and the second body 102 can rotate relative to each other based on an axis parallel to the first direction X.

[0069] In the electronic device provided in this application embodiment, the first radiator structure 104 and the second radiator structure 105 of the antenna assembly are disposed on the rotating shaft assembly 103. This allows the radiator structure of the antenna assembly and the rotating shaft assembly 103 to be integrated, eliminating the need to set the first radiator structure 104 and the second radiator structure 105 inside the first body 101 and the second body 102. This saves internal installation space in the first body 101 and the second body 102, making it easier to achieve a thinner and smaller design for the electronic device.

[0070] In addition, since the first radiator structure 104 and the second radiator structure 105 are both located outside the first body 101 and the second body 102, compared with the scheme of setting the radiator structure inside the device body, there is no need to consider the interference of electronic components and metal parts inside the body on the radiator structure. It can also make the radiator structure have a more sufficient clearance environment, which not only simplifies the device design, but also improves the performance of the antenna assembly. Moreover, the first body 101 and the second body 102 can both adopt an all-metal shell, which can make the first body 101 and the second body 102 have a better appearance and metallic texture.

[0071] Furthermore, the radiator structure of the antenna assembly is divided into two parts: a first radiator structure 104 and a second radiator structure 105. The first radiator structure 104 is disposed within the accommodating space of the rotating housing 106, and the second radiator structure 105 is disposed on the surface of the rotating housing 106. A feed signal can be fed into the antenna assembly through the first radiator structure 104, and the antenna assembly can transmit and receive wireless signals based on the coupling between the first radiator structure 104 and the second radiator structure 105.

[0072] The second radiator structure 105 is disposed on the surface of the pivot housing 106. The pivot housing 106 can be reused as a support for the second radiator structure 105, thus not occupying any space within the pivot housing 106. Furthermore, by using a smaller first radiator structure 104, the coupling relationship between the first and second radiator structures 104 allows for the resonant effect achieved by using only the larger first radiator structure in the antenna assembly. Therefore, this embodiment can achieve the desired resonant frequency using a smaller first radiator structure 104, resulting in a shorter length of the first radiator structure 104 in the first direction X. This reduces the length of the pivot housing 106, facilitating the ID design of the electronic device.

[0073] In this embodiment, the communication frequency band of the antenna assembly includes 2.402GHz~2.483GHz and 5.15GHz~7.125GHz, and the length of the first radiator structure 104 is less than 9mm. As described above, based on the coupling relationship between the first radiator structure 104 and the second radiator structure 105, the required resonant frequency can be achieved through a smaller length of the first radiator structure 104, reducing the length of the first radiator structure 104 to below 9mm, thereby significantly reducing the length of the rotating shaft housing 106.

[0074] Combination Figures 1-3 As shown, the rotating shaft assembly includes a first shaft structure 107 and a second shaft structure 108 that are rotatably connected. The first shaft structure 107 is connected to the first body 101, and the second shaft structure 108 is connected to the second body 102.

[0075] In one embodiment, the antenna assembly further includes: a bracket 109 disposed on a first axis structure 107 or a second axis structure 108, a first radiator structure 104 disposed on the bracket 109; and a feed line, the feed line including a first end and a second end disposed opposite to each other, the first end being connected to a feed source and the second end being connected to a feed point of the first radiator structure 104, so as to feed an excitation current into the first radiator structure 104.

[0076] The feed line and feed source are not shown in the accompanying drawings of this application embodiment. The feed source may be located within the first body 101 or the second body 102. The feed source is connected to the feed point of the first radiator structure 104 via a feed line. The feed source may be an antenna chip.

[0077] In another way, such as Figure 3 As shown, the rotating shaft assembly 103 also includes a bushing structure 110 connected to the first shaft structure 107 and the second shaft structure 108 to realize relative rotation between the two. The bracket 109 is disposed on the bushing structure 110. In this way, the influence of the relative rotation of the first shaft structure 107 and the second shaft structure 108 on the mechanical stability of the first radiator structure 104 can be reduced, so as to ensure the stability of the communication performance of the antenna assembly. At the same time, it is also convenient for the bracket 109 to be installed and fixed in the rotating shaft housing 106.

[0078] In one embodiment, the bracket 109, which houses the first radiator structure 104, can be attached to the bushing structure 110 by screws. The second radiator structure 105 is directly mounted on the rotating housing 106, which serves as the antenna support.

[0079] In this embodiment, the first radiator structure 104 and the second radiator structure 105 are not electrically connected; they work together via coupling. The desired resonant frequency can be achieved by designing their geometric structures. The second radiator structure 105 enriches the antenna assembly's tuning and optimizes its impedance matching. Without sacrificing antenna assembly performance, the length of the first radiator structure 104 is significantly shortened, thereby reducing the length of the support 109. Consequently, the length of the rotating shaft housing 106 is also reduced.

[0080] Optionally, the antenna assembly also includes an antenna ground, which is not shown in the accompanying drawings of this embodiment. The feed line includes an inner conductor and a braided layer wrapping the inner conductor. The feed line is connected to a feed point through the inner conductor and connected to the antenna ground through the braided layer. The antenna ground is a first body 101 or a second body 102 made of a metal shell. The first radiator structure 104 includes a ground point and a feed point. The ground point is connected to the braided layer of the feed line to connect to the antenna ground; the feed point is connected to the inner conductor of the feed line to connect to the feed source, thereby realizing a loop path for the antenna circuit. This method uses the metal shell of the first body 101 or the second body 102 as the antenna ground, eliminating the need for additional antenna ground design and simplifying the design.

[0081] refer to Figure 5 , Figure 5 for Figure 4 The diagram shows a cross-sectional view of the shaft housing along the P-P' direction. Figure 1 As shown, the pivot assembly 103 extends along a first direction X, and the first body 101 and the second body 102 are capable of rotating based on an axis parallel to the first direction X. Figure 5 As shown, the first radiator structure 104 and the second radiator structure 105 at least partially overlap in the second direction Y, which is perpendicular to the first direction X.

[0082] like Figure 5 As shown, since the first radiator structure 104 and the second radiator structure 105 overlap at least partially in the second direction Y, they can form a capacitive coupling. The feed signal fed into the first radiator structure 104 from the feed source can be coupled to the second radiator structure 105, so that the antenna assembly can transmit and receive wireless signals through the first radiator structure 104 and the second radiator structure 105.

[0083] Optionally, the distance between the first radiator structure 104 and the second radiator structure 105 in the second direction is 0.3mm to 3mm. Within this distance range, problems such as difficulty in electrical isolation and difficulty in assembling the radiator structures caused by too small a distance between the two radiator structures can be avoided. It can also make the two radiator structures form a strong coupling effect, and avoid the coupling effect between the two radiator structures being affected by too large a distance between them.

[0084] In some embodiments of this application, the electronic device further includes a passive device located within the pivot housing 106, which is electrically connected to the first radiator structure 104. This method utilizes the existing accommodating space of the pivot housing 106 to arrange the passive device, thereby further optimizing the impedance matching of the antenna assembly without occupying the installation space inside the device body.

[0085] Passive devices are not shown in the accompanying drawings of the embodiments of this application. Passive devices can be capacitors, inductors, capacitors and inductors in series, or capacitors or inductors in parallel.

[0086] In one embodiment, the second radiator structure 105 is a patterned metal layer formed on the surface of the pivot housing 106. In this way, the first radiator structure 104 can be mounted in the pivot housing 106 by a bracket 109, while the second radiator structure 105 can utilize the pivot housing 106 as an antenna bracket, which can reduce the number of antenna brackets, reduce costs, and facilitate the miniaturization design of the product.

[0087] In electronic devices, one method can be as follows: Figure 2 and Figure 4 As shown, the second radiator structure 105 is formed directly on the outer surface of the shaft housing 106. Alternatively, the second radiator structure 105 may be formed directly on the inner surface of the shaft housing 106.

[0088] refer to Figure 6 , Figure 6This is a schematic diagram of a rotating housing provided in an embodiment of this application. The rotating housing is an insulating material housing structure. The insulating housing has a receiving cavity, and one side of the receiving cavity has an opening 113. The insulating housing has an inner surface 112 and an outer surface 111, on which the second radiator structure 105 can be disposed. The insulating housing can accommodate the first radiator structure 104 and the portion of the rotating assembly 103 on which the first radiator structure 104 is mounted, based on the opening 113. The insulating material housing facilitates the first radiator structure 104 to transmit and receive wireless signals without causing electromagnetic shielding to the antenna signal.

[0089] Alternatively, the insulating housing can be an LDS (laser direct forming) component or other insulating structural components used for printing antenna pattern structures.

[0090] In this embodiment, the first radiator structure 104 can adopt the pattern structure of an IFA antenna, a LOOP antenna, or a Monopolole antenna. The pattern structure of the first radiator structure 104 can be designed according to requirements, and the pattern structure of the first radiator structure 104 in this embodiment is not limited.

[0091] Optionally, to further shorten the length of the first radiator structure 104 in the first direction X, such as Figure 3 As shown, the first radiator structure 104 can be a non-closed polygonal structure.

[0092] In one embodiment, the second radiator structure 105 can be as follows: Figure 2 or Figure 4 As shown, this is a metal block with a defined graphic structure. In other embodiments, the second radiator structure 105 can also be as follows: Figures 7-9 As shown in any of the methods.

[0093] refer to Figure 7 , Figure 7 This is a schematic diagram of a second radiator structure provided in an embodiment of this application. In this structure, the second radiator structure 105 includes a first conductor portion 114 and a second conductor portion 115 arranged coplanarly, with an electrically isolated gap between them. The first conductor portion 114 and the second conductor portion 115 can be metal blocks or other conductive material blocks, such as conductive metal oxides. This method optimizes the impedance matching effect of the second radiator structure 105 by adjusting the size and relative position of the two conductor portions.

[0094] refer to Figure 8 , Figure 8This is a schematic diagram of another second radiator structure provided in an embodiment of this application. In this configuration, the second radiator structure 105 includes a conductor block 117 and a wire 116 integrally connected to the conductor block 117, with the wire 116 surrounding the conductor block 117. This configuration optimizes the impedance matching effect of the second radiator structure 105 by adjusting at least one of the following: the graphic structure of the conductor block 117, the gap width between the wire 116 and the conductor block 117, and the length of the wire 116.

[0095] refer to Figure 9 , Figure 9 This is a schematic diagram of another second radiator structure provided in an embodiment of this application. In this embodiment, the second radiator structure 105 includes a conductor layer 118, the conductor layer 118 having a hollowed-out slot 119 inside. The hollowed-out slot 119 is a closed slot located inside the periphery of the conductor layer 118, that is, there is a preset distance between the hollowed-out slot 119 and the periphery of the conductor layer 118. In this embodiment, the conductor layer 118 covers one side surface of the rotating shaft housing 106. The impedance matching effect of the second radiator structure 105 can be optimized by adjusting the graphic structure and relative position of the internal hollowed-out slot 119.

[0096] The graphic structure of the second radiator structure 105 can be set according to requirements, and is not limited to... Figures 7-9 As shown, the graphic structure of the second radiator structure 105 can be a segmented graphic structure, a spiral graphic structure, or a graphic structure with gaps, etc.

[0097] exist Figure 2 , Figure 4 , Figures 7-9 The illustrations all use the example of the second radiator structure 105 being disposed on the outer surface of one side of the rotating shaft housing 106. In other embodiments, the second radiator structure 105 can also be disposed on the inner surface of one side of the rotating shaft housing 106. When the second radiator structure 105 is formed on the inner surface of the rotating shaft housing 106, processes such as PDS can be used to print the second radiator structure 105 onto the inner surface of the rotating shaft housing 106, eliminating the need for spraying. Compared to the solution of disposing it on the outer surface of the rotating shaft housing 106, this reduces costs.

[0098] When the second radiator structure 105 is disposed on the outer surface of one side of the shaft housing 106, in order to increase the layout area of ​​the second radiator structure 105, the second radiator structure 105 can be disposed on the outer surface of at least two sides of the shaft housing 106 to improve its impedance matching effect.

[0099] When the second radiator structure 105 is disposed on the inner surface of one side of the shaft housing 106, in order to increase the layout area of ​​the second radiator structure 105, the second radiator structure 105 can be disposed on the inner surface of at least two sides of the shaft housing 106 to improve its impedance matching effect.

[0100] Since the antenna assembly provided in this embodiment includes two radiating structures, the first radiating structure 104 and the second radiating structure 105 need to be jointly debugged. The debugging method for the antenna assembly can be as follows: Figure 10 As shown.

[0101] refer to Figure 10 , Figure 10 This application provides a flowchart illustrating a debugging method for an antenna assembly, which includes:

[0102] Step S11: Initially adjust the first radiator structure 104 to near the required resonant frequency.

[0103] After obtaining the fixture or simulation model, the design of the second radiator structure 105 is not considered at first. Similar to the traditional design scheme, the first radiator structure 104 is optimized and debugged separately. The graphic structure of the first radiator structure 104 can be in the form of an IFA antenna, a LOOP antenna, or a Monopole antenna. During the debugging process, passive components can also be added to optimize the matching until the generated resonance is near the required resonant frequency.

[0104] Step S12: Add the second radiator structure 105 and jointly debug to the final result.

[0105] After completing the initial debugging, the second radiator structure 105 is added for joint debugging. The graphic structure of the second radiator structure 105 can further optimize the matching of the entire antenna assembly. Through continuous optimization, good resonance requirements can be obtained.

[0106] The following section will explain the debugging method in detail by taking the debugging process of the antenna component graphic structure of an actual project in the general electromagnetic simulation software CST.

[0107] refer to Figures 11-13 , Figures 11-13 This is a schematic diagram illustrating the principle of preliminary debugging based on the first radiator structure. Figure 11 The first body 101 and the second body 102 are rotatably connected based on the rotating shaft assembly 103, which is a three-dimensional model of the electronic device to be debugged. Figure 12 for Figure 11 A partially enlarged schematic diagram of the electronic device shown. Figure 13 for Figure 12This is a schematic diagram of the electronic device after the hinge housing 106 has been removed. Figure 12 and Figure 13 As shown, the pivot assembly 103 is connected to the bracket 109.

[0108] Following the requirements of the simulation software, after setting the parameters of each component of the model, the software can be run to begin designing the graphic structure of the first radiator structure 104. Referring to traditional design schemes, the following preliminary antenna graphic structure design was obtained: Figure 14 and Figure 15 The simulation results are shown.

[0109] refer to Figure 14 and Figure 15 , Figure 14 The S-parameter curves of the antenna assembly after initial debugging based solely on the first radiator structure. Figure 15 Smith chart of the antenna assembly after initial debugging based on the first radiator structure.

[0110] based on Figure 14 The test results show that, after debugging based solely on the first radiator structure 104, the antenna assembly exhibits poor impedance matching and shallow resonance at 6GHz. Figure 15 The Smith chart shown confirms this, with the resonant frequency range located in the fourth quadrant, which is far from the center point of the optimal match.

[0111] refer to Figure 16 , Figure 16 A schematic diagram of a simulation model of an electronic device after adding a second radiator structure to the hinge housing. Based on... Figures 11-13 After initial debugging of the first radiator structure 104, the model shown is as follows: Figure 16 The model shown incorporates a second radiator structure 105 onto the rotating housing 106. The design begins with the graphical structure of the second radiator structure 105 on the rotating housing 106. Through continuous optimization of the second radiator structure 105, the S-parameters of the antenna assembly can be improved. The optimized simulation results are shown below. Figure 17 and Figure 18 As shown.

[0112] refer to Figure 17 and Figure 18 , Figure 17 The S-parameter curves of the antenna assembly after joint debugging based on the first and second radiator structures are shown. Figure 18 The Smith chart shows the antenna assembly after joint debugging based on the first and second radiator structures.

[0113] like Figure 17As shown, after adding the second radiator structure 105 for joint debugging, the impedance matching effect of the antenna assembly at 6GHz is improved, and the impedance matching effect becomes better, as shown in the figure. Figure 18 As shown in the original Smith chart, the resonant frequency band at 6 GHz is closer to the center point. Therefore, the impedance matching of the antenna assembly can be further optimized by using the second radiator structure 105 mounted on the rotating shaft housing 106, resulting in better antenna performance.

[0114] refer to Figure 19 and Figure 20 , Figure 19 This is a schematic diagram of the current distribution near the rotating shaft assembly after the antenna assembly has undergone preliminary debugging based solely on the first radiator structure. Figure 20 This is a schematic diagram of the current distribution near the rotating shaft assembly after the antenna assembly has been jointly debugged based on the first radiator structure and the second radiator structure.

[0115] Furthermore, by comparing the current distribution in phase at 6 GHz using CST software, based on... Figure 19 As shown in the current distribution, the current distribution near the shaft assembly 103 is significantly different before and after adding the second radiator structure 105. Without the second radiator structure 105, the current is concentrated on the shaft assembly 103. After adding the second radiator structure 105, the current distribution is more uniform. Based on this, it can be seen that impedance matching can be optimized by using the second radiator structure 105.

[0116] In addition, the actual debugging and verification results of the actual machine show that, according to the above debugging method, the length of the first radiator structure 104 can be reduced from 9mm to about 4mm, which is about 55% smaller than the conventional length, greatly shortening the length of the required support 109.

[0117] Based on the design scheme of this application embodiment, the antenna assembly can cover the WLAN7 protocol, with communication frequency bands of 2.402GHz~2.483GHz and 5.15GHz~7.125GHz. The antenna efficiency test results for the corresponding antenna assembly are as follows: Figure 21 As shown.

[0118] refer to Figure 21 , Figure 21 This is a comparison chart of antenna efficiency of an antenna assembly in an electronic device provided in an embodiment of this application. Figure 21The horizontal axis represents frequency in Hz, and the vertical axis represents antenna efficiency in dB. Curve L1 is the antenna efficiency curve of a comparison antenna with only one radiator structure, the length of which is 4 mm in the first direction X. Curve L2 is the antenna efficiency curve of an antenna assembly with a first radiator structure 104 and a second radiator structure 105, the first radiator structure 104 having a length of 4 mm in the first direction X. Curve L3 is the antenna efficiency curve of the original antenna design, where the radiator structure has a length of 9 mm in the first direction X.

[0119] like Figure 21 As shown in curve L1, when the length of the single radiator structure is reduced to 4mm, the antenna performance cannot achieve good impedance matching in the 5GHz band, and the antenna performance is only at a level of about -9dB.

[0120] like Figure 21 As shown in curve L2, after joint debugging based on the first radiator structure 104 and the second radiator structure 105, the impedance of the 5GHz band was significantly optimized, and the performance was improved by about 3dB. The performance was basically consistent with the original antenna design with a radiator structure length of 9mm, thus verifying that the implementation method provided in this application can greatly reduce the length of the radiator structure while maintaining the antenna performance, and can greatly reduce the length of the rotating housing 106.
