For foldable phones with metal frames, the seam between the secondary screen and the main screen frames is consistent when folded. Currently, the secondary screen structure is usually grounded with a physical metal structure, but this directly leads to a sharp deterioration in antenna clearance. Therefore, existing technologies suffer from poor communication performance in foldable electronic devices. Summary of the Invention

[0024] See Figure 1 and Figure 2 This application provides an electronic device, such as... Figure 1 and Figure 2 As shown, the electronic device includes: a first device body and a second device body, wherein the first device body has a folded state and an unfolded state relative to the second device body; the first device body includes a first frame 11 and a first metal radiating plate 12, wherein the first frame 11 is provided with a first antenna radiator 111 and a first slit 112 located on both sides of the first antenna radiator 111, and the first metal radiating plate 12 is electrically connected to the first antenna radiator 111; the second device body includes a second frame 21 and a second metal radiating plate 22, wherein the second frame 21 is provided with a second antenna radiator 211 and a second slit 212 located on both sides of the second antenna radiator 211, and the second metal radiating plate 22 is electrically connected to the second antenna radiator 211;

[0025] The first antenna radiator 111 is provided with a feed connection point, the first antenna radiator 111 is provided corresponding to the second antenna radiator 211, the first slit 112 is provided corresponding to the second slit 212, and in the folded state, the first antenna radiator 111 and the second antenna radiator 211 are coupled and connected through the first metal radiating sheet 12 and the second metal radiating sheet 22.

[0026] In this embodiment, the aforementioned electronic device can be understood as a foldable screen setup, wherein the first device body can be understood as a main screen device, and the second device body can be understood as a secondary screen device. The first frame 11 and the second frame 21 can be metal frames, which can be hollowed out to form the first slit 112 and the second slit 212, wherein there are two first slits 112 and two second slits 212. A first antenna radiator 111 is formed by setting two first slits 112 on the first frame 11, and a second antenna radiator 211 is formed by setting two second slits 212 on the second frame 21.

[0027] Optionally, the arrangement of the first antenna radiator 111 corresponding to the second antenna radiator 211 can be understood as the first antenna radiator 111 and the second antenna radiator 211 being positioned and sized substantially the same. Similarly, the arrangement of the first slit 112 corresponding to the second slit 212 can be understood as the first slit 112 and the second slit 212 being positioned and sized substantially the same. For example, in the folded state, the first antenna radiator 111 and the second antenna radiator 211 are arranged parallel to each other, and the first slit 112 and the second slit 212 are in the same position.

[0028] It should be understood that in order to achieve power supply, a feed source and a matching network are usually required. For example... Figure 1 As shown, the main body of the first device also includes: a feed source 13, a second matching network 14, a third matching network 15, and a second switch structure 16. The feed source 13 is electrically connected to the power supply connection point through the second matching network 14, and the power supply connection point is also grounded through the third matching network 15 and the second switch structure 16.

[0029] In this embodiment, the feed source 13, the second matching network 14 and the third matching network 15 and the second switch structure 16 can be disposed on the motherboard 31 of the first device body.

[0030] Optionally, the second matching network may include a switching structure and branches comprising at least one of the following: a directly grounded branch (i.e., a branch without an inductor or capacitor); an inductor branch; a capacitor branch; or an inductor and capacitor connected in series. The switching structure can control the feed connection point to be electrically connected to the feed source through the corresponding branch.

[0031] Optionally, the third matching network 15 may include at least one of the following branches: a direct grounding branch; an inductor branch; a capacitor branch; or an inductor and capacitor connected in series. The second switching structure 16 can control the feed connection point to be electrically connected to the ground terminal through the corresponding branch.

[0032] It should be noted that in this embodiment of the application, a suspended antenna structure is constructed by setting second slits 212 on both sides of the second antenna radiator 211. At the same time, a second metal radiating plate 22 is set to connect with the second antenna radiator 211, thereby forming a double-slit "T"-shaped antenna structure.

[0033] Optionally, the first and second gaps 112 and 212 can be filled with non-metallic material, and no grounding connection point is provided on the second antenna radiator 211 (or the part of the second frame other than the second antenna radiator 211 can be grounded), nor is a tuning circuit provided (one end of the tuning circuit is used for grounding connection, and the other end is used for connection with the corresponding radiator). In this way, when in the folded state, the second antenna radiator 211 is in a suspended state relative to the first antenna radiator 111. The second antenna radiator 211 will not form a parasitic structure on the first antenna radiator 111, and the excitation differential mode radiation will not affect the feed. Therefore, no tuning processing is required on the second device body, that is, no tuning circuit is required on the second device body.

[0034] It should be understood that when the second antenna radiator 211 is suspended relative to the first antenna radiator 111 (i.e., when the first device body is folded relative to the second device body), the second antenna radiator 211 excites a high-frequency differential-mode current mode (such as 1 / 2 mode) and can produce a radiation enhancement effect on the first antenna radiator 111 in the corresponding operating frequency band. However, when the second antenna radiator 211 operates in a non-differential-mode current mode (such as non-1 / 2 mode), the close proximity of the second antenna radiator 211, as a metal structure, to the first antenna radiator 111 will cause a deterioration of the feed antenna environment and a decrease in performance. By setting the first metal radiating plate 12 and the second metal radiating plate 22 to form a coupled connection structure, the second antenna radiator 211 can be excited to form the same symmetrical current distribution as the first antenna radiator 111. In this way, the feed can achieve performance improvement in any mode, and the optimal coupling effect can be achieved by adjusting the area of ​​the first metal radiating plate 12 and the second metal radiating plate 22.

[0035] Optionally, the first metal radiating sheet 12 and the second metal radiating sheet 22 may include, but are not limited to, radiating sheets made using laser-direct-structuring (LDS) technology, printing direct structure (PDS) technology, or flexible printed circuit (FPC) or metal sheets as radiating sheets.

[0036] In this embodiment, the first device body is configured to have a folded state and an unfolded state relative to the second device body. The first device body includes a first frame 11 and a first metal radiating plate 12. The first frame 11 is provided with a first antenna radiator 111 and a first slit 112 located on both sides of the first antenna radiator 111. The first metal radiating plate 12 is electrically connected to the first antenna radiator 111. The second device body includes a second frame 21 and a second metal radiating plate 22. The second frame 21 is provided with a second antenna radiator 211 and a second slit 212 located on both sides of the second antenna radiator 211. The second metal radiating plate 22 is electrically connected to the second antenna radiator 211. The first antenna radiator 111 is provided with a feed connection point. The first antenna radiator 111 is configured corresponding to the second antenna radiator 211. In the folded state, the first slit 112 is configured corresponding to the second slit 212. The first antenna radiator 111 and the second antenna radiator 211 are coupled and connected through the first metal radiating plate 12 and the second metal radiating plate 22. In this way, the second antenna radiator 211 can be excited to form the same symmetrical current distribution as the first antenna radiator 111, thereby enhancing the radiation effect of the first antenna radiator 111. Therefore, the embodiments of this application can improve the communication performance of the folding device.

[0037] Optionally, in some embodiments, when the first device body is in a folded state relative to the second device body, the distance between the first metal radiating plate 12 and the second metal radiating plate 22 is less than the distance between the first antenna radiator 111 and the second antenna radiator 211.

[0038] In this embodiment, by setting the distance between the first metal radiating plate 12 and the second metal radiating plate 22 to be less than the distance between the first antenna radiator 111 and the second antenna radiator 211, the coupling effect between the first metal radiating plate 12 and the second metal radiating plate 22 can be guaranteed, thereby further improving the performance of the antenna.

[0039] Optionally, the distance between the first metal radiating plate 12 and the second metal radiating plate 22 can be set according to actual needs. For example, in some embodiments, when the first device body is in a folded state relative to the second device body, the distance between the first metal radiating plate 12 and the second metal radiating plate 211 is equal to the minimum distance between the first device body and the second device body. In this way, the coupling effect between the first metal radiating plate 12 and the second metal radiating plate 22 can be increased, thereby improving the performance of the antenna.

[0040] Optionally, such as Figure 3 and Figure 4 As shown in this embodiment, the first antenna corresponding to the first antenna radiator 111 operates in the MHB band (1.71 GHz to 2.7 GHz). The first antenna radiator 111 can excite a 1 / 4 common-mode current mode "M1" and a 1 / 2 differential-mode current mode "M2". By coupling the second metal radiator 22 to the first metal radiator 12, the second antenna radiator 211 can be excited to generate a symmetrical 1 / 4 common-mode current distribution (i.e., 1 / 4 common-mode current mode "M3") and a 1 / 2 differential-mode current distribution (i.e., 1 / 2 common-mode current mode "M4").

[0041] Optionally, such as Figure 5 As shown, solid line A1 represents the radiation efficiency curve of the first radome in the unfolded state, dashed line B1 represents the radiation efficiency curve of the first radome in the folded state without the addition of the first metal radiating plate 12 and the second metal radiating plate 22, and dashed line C1 represents the radiation efficiency curve of the first radome in the folded state with the addition of the first metal radiating plate 12 and the second metal radiating plate 22 (i.e., applying the scheme of this application). Figure 5 As can be seen, compared to the unfolded state, the second antenna radiator 211 is suspended relative to the first antenna radiator 111 in the folded state. The performance of the first antenna is improved within the 1 / 2 mode current mode frequency band (2.0GHz~2.7GHz) excited by the second antenna radiator 211, but the sub-screen structure "2" cannot be excited in other frequency bands, causing environmental degradation and performance decline for "1". When the solution of this application is adopted, in the folded state, the second metal radiator 22 is coupled through the first metal radiator 12 at the feed connection point of the first antenna radiator 111, thereby exciting the second antenna radiator 211 to form the same symmetrical current distribution as the first antenna radiator 111. This effectively compensates for the performance degradation caused by the second antenna radiator 211. Thus, the folded state performance of the first antenna is improved compared to the unfolded state across the entire frequency band (1.7GHz~2.7GHz).

[0042] It should be noted that, in the embodiments of this application, the switching of different frequency bands of the first antenna can be realized through the third matching network 15 and the second switching structure 16 set in the first antenna.

[0043] Optionally, in some embodiments, the first device body further includes a first metal connector 121, and the first metal radiating sheet 12 is electrically connected to the first antenna radiator 111 through the first metal connector 121.

[0044] And / or, the second device body further includes a second metal connector 221, and the second metal radiating plate 22 is electrically connected to the second antenna radiator 211 through the second metal connector 221.

[0045] In this embodiment, the specific structures of the first metal connector 121 and the second metal connector 221 can be configured according to actual needs. For example, in some embodiments, the first metal connector 121 and / or the second metal connector 221 are metal springs. Using metal springs to achieve the electrical connection between the first metal radiating plate 12 and the first antenna radiator 111 and the second metal radiating plate 22 and the second antenna radiator 211 has a simple structure, is easy to assemble, and is beneficial to industrial production.

[0046] Of course, in other embodiments, the first metal connector 121 can be integrally connected with the first metal radiating sheet 12, and similarly, the second metal connector 221 can be integrally connected with the second metal radiating sheet 22.

[0047] Optionally, in some embodiments, the position where the first antenna radiator 111 is electrically connected to the first metal radiating plate 12 is a first position, and the position where the second antenna radiator 211 is electrically connected to the second metal radiating plate 22 is a second position, wherein the first position corresponds to the second position, and the first position is the position where the feed connection point is located.

[0048] In this embodiment, the correspondence between the first position and the second position can be understood as the same position being the same as the second position. That is, the coordinates of the first position on the first antenna radiator 111 are the same as the coordinates of the second position on the second antenna radiator 211. This ensures that the first antenna radiator 111 and the second antenna radiator 211 have the same feed position, thereby ensuring that the first antenna radiator 111 and the second antenna radiator 211 have the same symmetrical current distribution, further improving the communication performance of the antenna.

[0049] It should be noted that in some embodiments, the first metal radiating sheet 12 is perpendicular to the first antenna radiator 111, the second metal radiating sheet 22 is perpendicular to the second antenna radiator 211, and in the folded state, the first metal radiating sheet 12 is parallel to the second antenna radiator 211. This can improve the feed coupling effect and thus improve the antenna performance.

[0050] Optionally, please refer to the following: Figure 6 and Figure 7In some embodiments, the first device body further includes a third metal radiating sheet 17, a first matching network 18, and a first switch structure 19. The third metal radiating sheet 17 is electrically connected to the first matching network 18, and the first matching network 18 is grounded through the first switch structure 19. The second device body further includes a fourth metal radiating sheet 20, which is electrically connected to the second antenna radiator 211. The third metal radiating sheet 17 and the fourth metal radiating sheet 20 are coupled together.

[0051] In this embodiment, the first matching network 18 and the first switching structure 19 can be disposed on the motherboard 31 of the first device body. The third metal radiating plate 17, the first matching network 18, the first switching structure 19, and the fourth metal radiating plate 20 can constitute a tuning network. This tuning network can be used to coordinate the common-mode current mode (such as 1 / 4 common-mode current mode "M5") excited by the second antenna radiator 211 with better radiation efficiency to work together with the common-mode current mode (1 / 4 common-mode current mode "M1") excited by the first antenna radiator 111, so that the radiation efficiency of the first antenna can be further improved. For example, when the first antenna operates in the B3 band (1.71GHz~1.88GHz), the current distribution of the 1 / 4 common-mode current mode "M1" excited by the first antenna radiator 111 and the 1 / 4 common-mode current mode "M5" excited by the second antenna radiator 211 working simultaneously is as follows: Figure 8 As shown.

[0052] Optionally, the first matching network 18 may include at least one of the following branches: a direct grounding branch; an inductor branch; a capacitor branch; or an inductor and capacitor connected in series. The first switching structure 19 can control the third metal radiating plate 17 to be electrically connected to the ground terminal through the corresponding branch.

[0053] Optionally, in some embodiments, the first device body further includes a third metal connector 171, and the third metal radiating sheet 17 is electrically connected to the first matching network 18 through the third metal connector 171.

[0054] And / or, the second device body further includes a fourth metal connector 201, through which the fourth metal radiating plate 20 is electrically connected to the second antenna radiator 211.

[0055] In this embodiment, the specific structures of the third metal connector 171 and the fourth metal connector 201 can be configured according to actual needs. For example, in some embodiments, the third metal connector 171 and / or the fourth metal connector 201 are metal springs. Using metal springs to achieve the electrical connection between the third metal connector 171 and the first matching network 18 and the fourth metal connector 201 and the second antenna radiator 211 has a simple structure, is easy to assemble, and is beneficial to industrial production.

[0056] Of course, in other embodiments, the third metal connector 171 can be integrally connected with the third metal radiating sheet 17, and similarly, the fourth metal connector 201 can be integrally connected with the fourth metal radiating sheet 20.

[0057] Optionally, in some embodiments, the first matching network 18 is used to control the resonant frequency of the second antenna radiator 211 to be less than the resonant frequency of the first antenna radiator 111 in the deployed state.

[0058] It should be understood that, in the unfolded state, the aforementioned tuning network allows the resonant frequency f2 of the second antenna radiator 211 to be lower than the resonant frequency f1 of the first antenna radiator 111. This ensures that the operating frequency band of the first antenna is consistent in both the unfolded and folded states. Figure 9 As shown. In this way, although the folded state does not achieve the optimal radiation efficiency, it can improve the system efficiency by about 1 dB in the B3 band compared to the case without the third metal radiating plate 17 and the fourth metal radiating plate 20.

[0059] Among them, the comparison between radiation efficiency and system efficiency in different scenarios is as follows: Figures 10 to 11 As shown.

[0060] exist Figure 9 In the diagram, solid line A2 represents the S-parameter curve of the first ray in the unfolded state, dashed line B2 represents the S-parameter curve of the first ray in the folded state without the addition of the third metal radiating plate 17 and the fourth metal radiating plate 20, and dashed line C2 represents the S-parameter curve of the first ray after the addition of the third metal radiating plate 17 and the fourth metal radiating plate 20 in the folded state.

[0061] exist Figure 10In the diagram, solid line A3 represents the radiation efficiency curve of the first ray in the unfolded state, dashed line B3 represents the radiation efficiency curve of the first ray in the folded state without the addition of the third metal radiating plate 17 and the fourth metal radiating plate 20, and dashed line C3 represents the radiation efficiency curve of the first ray after the addition of the third metal radiating plate 17 and the fourth metal radiating plate 20 in the folded state.

[0062] exist Figure 11 In the diagram, solid line A4 represents the system efficiency curve of the first antenna in the unfolded state, dashed line B4 represents the system efficiency curve of the first antenna in the folded state without the addition of the third metal radiating plate 17 and the fourth metal radiating plate 20, and dashed line C4 represents the system efficiency curve of the first antenna after the addition of the third metal radiating plate 17 and the fourth metal radiating plate 20 in the folded state.

[0063] It should be noted that, in this embodiment, the switching of different frequency bands of the first antenna can be achieved through the third matching network 15 and the second switching structure 16 set in the first antenna. Furthermore, by combining the first matching network 18 and the first switching structure 19 to tune the resonance of the second antenna radiator 211, a high-performance antenna design for different frequency bands of the first antenna can be achieved to meet the coverage requirements of multiple operating frequency bands.
