However, with the increasing number of antennas integrated into electronic devices such as mobile phones, and due to the limitations of the grounding and feed point locations of different antennas, it is difficult for the antenna energy to be coupled and distributed across the symmetrical structure area.

Figure 1 As shown, the electronic device provided in the embodiment of the present application includes: a metal frame 10, a camera module 20, a first antenna, a second antenna and a third antenna, the camera module 20 is located on the inner side of the metal frame 10, and the camera module 20 includes a metal decorative ring 21, and the metal decorative ring 21 is grounded;

[0021] The metal frame 10 includes a first frame 11, a second frame 12, and a third frame 13 that are adjacent to each other in sequence. The first frame 11 and the third frame 13 are arranged opposite to each other, and the camera module 20 is located in the area enclosed by the first frame 11 and the second frame 12.

[0022] The first antenna includes a first radiating branch 111 disposed on the first frame 11 , and the first radiating branch 111 is located at an end of the first frame 11 close to the second frame 12 ;

The third radiating branch 123 is located at an end of the second frame 12 close to the third frame 13, and the fourth radiating branch 131 is located at an end of the third frame 13 close to the second frame 12.

[0025] A first break 14 is provided between the first radiation branch 111 and the second radiation branch 121, a second break 15 is provided between the third radiation branch 123 and the fourth radiation branch 131, a gap is provided between the first radiation branch 111 and the metal decorative ring 21, and the first radiation branch 111 and the metal decorative ring 21 are coupled and connected, and the energy of the first antenna can be transmitted to the area where the third antenna is located through the metal decorative ring 21.

[0026] The above-mentioned metal frame 10 can be understood as the frame structure of the electronic device. For rectangular electronic devices such as mobile phones, the metal frame 10 may include a first long frame, a first short frame, a second long frame and a second short frame connected end to end in sequence. The first long frame and the second long frame can be understood as two relatively set frame structures of the electronic device, the first short frame and the second short frame can be understood as two relatively set frame structures of the electronic device, and the two short frames can also be understood as the top frame and bottom frame of the electronic device.

[0027] Among them, the first long frame, the first short frame, the second long frame and the second short frame connected end to end can be understood as: the second end of the first long frame is connected to the first end of the first short frame, the second end of the first short frame is connected to the first end of the second long frame, the second end of the second long frame is connected to the first end of the second end frame, and the second end of the second short frame is connected to the first end of the first long frame.

[0028] In some embodiments, the electronic device may further include a metal middle frame, which may include an inner frame and an outer frame. The outer frame may be connected to the inner frame via structures such as connecting ribs. The metal frame 10 may be understood as the outer frame of the metal middle frame.

[0029] The above-mentioned first antenna can be understood as an antenna structure arranged on the first frame 11, and the radiator of the first antenna is the first radiating branch 111 arranged on the first frame 11; in addition, the first antenna can also include a first feed source 31 electrically connected to the first radiating branch 111, and the feed signal output by the first feed source 31 can excite the first radiating branch 111 to put the first antenna into working state.

[0030] The above-mentioned second antenna can be understood as an antenna structure arranged on the second frame 12, and the radiator of the second antenna is the second radiating branch 121 arranged on the second frame 12; in addition, the second antenna can also include a second feed source 32 electrically connected to the second radiating branch 121, and the feed signal output by the second feed source 32 can excite the second radiating branch 121 to put the second antenna into a working state.

[0031] The above-mentioned third antenna can be understood as an antenna structure arranged on the second frame 12 and the third frame 13, and the radiator of the third antenna includes a third radiating branch 123 arranged on the second frame 12 and a fourth radiating branch 131 arranged on the third frame 13; in addition, the third antenna can also include a third feed source 33 electrically connected to the third radiating branch 123, and the third radiating branch 123 can be coupled with the fourth radiating branch 131 through the second slit 15. The feed signal output by the third feed source 33 can excite the third radiating branch 123 and the fourth radiating branch 131 to put the third antenna in a working state.

[0032] The grounding of the metal decorative ring 21 can be understood as the electrical connection between the metal decorative ring 21 and the ground structure of the electronic device. For example, the metal decorative ring 21 can be electrically connected to the ground structure on the mainboard of the electronic device via a conductive structure such as foam, metal springs, or conductive fabric to achieve grounding of the metal decorative ring 21.

[0033] The camera module 20 is located inside the metal frame 10, which can be understood as the camera module 20 being located within the space enclosed by the metal frame 10. In addition, when the electronic device is a mobile phone, the camera module 20 can be a rear camera module of the electronic device.

[0034] In this way, by coupling the first radiating branch 111 with the grounded metal decorative ring 21, the first antenna can also couple energy in the area where the metal decorative ring 21 is located and provide an energy transmission channel. The metal decorative ring 21 can be used to couple the energy excited by the first radiating branch 111 to the other side of the electronic device. Even if the energy excited by the first radiating branch 111 can be coupled to the side where the third antenna is located, the spatial coverage of the directional pattern of the first antenna is improved, thereby achieving the purpose of significantly reducing the spatial signal blind spot when the antenna is working.

[0035] In some embodiments, the first frame 11 can be a long frame or side frame of an electronic device such as a mobile phone, and the first radiating branch 111 can be an end of a short frame or a top frame close to the electronic device set on the first frame 11; in this way, by utilizing the coupling connection between the first radiating branch 111 and the metal decorative ring 21, the energy excited by the first radiating branch 111 can be coupled to the side where the other side frame of the electronic device is located through the metal decorative ring 21, thereby changing the mode current weight and field distribution characteristics of the first antenna, and achieving the purpose of improving the spatial coverage of the radiation pattern of the first antenna.

[0036] For example, when the first radiating branch 111 is a radiator arranged in the upper left corner area of ​​the mobile phone, and the metal structure of the top frame of the mobile phone does not resonate in the operating frequency band of the first antenna, making it difficult to couple the energy of the first antenna, the antenna energy can be coupled to the upper right corner area of ​​the mobile phone through the metal decorative ring 21 through the coupling of the first radiating branch 111 and the metal decorative ring 21, so as to improve the spatial coverage of the first antenna radiation pattern.

[0037] The first frame 11 can be grounded through the first conductive structure, and the ground connection point on the first frame 11 electrically connected to the first conductive structure divides the first frame 11 into the first radiation branch 111 and the first frame body 112 .

[0038] In some embodiments, the first conductive structure may be a conductive structure such as a spring or a connecting rib for electrically connecting the first frame 11 and a ground structure of the electronic device.

[0039] For example, when the first frame 11 is an outer frame of a metal middle frame, the first conductive structure may be a connecting rib for connecting the outer frame and the inner frame.

[0040] It can be understood that the second frame 12 also includes a second frame body 122, the second radiation branch 121 can be set at the end of the second frame body 122 close to the first frame 11, and the third radiation branch 123 can be set at the end of the second frame body 122 close to the third frame 13, and the end of the second radiation branch 121 connected to the second frame body 122 is grounded, and the end of the third radiation branch 123 connected to the second frame body 122 is grounded.

[0041] Among them, one end of the second radiation branch 121 connected to the second frame body 122 can be grounded through the second conductive structure, and one end of the third radiation branch 123 connected to the second frame body 122 can be grounded through the third conductive structure, that is, the second frame 12 can be divided into the second radiation branch 121, the second frame body 122 and the third radiation branch 123 through the second conductive structure and the third conductive structure.

[0042] The second frame 12 is divided into the second radiation branch 121, the second frame body 122 and the third radiation branch 123 by the second conductive structure and the third conductive structure. It can be understood that the ground connection point on the second frame 12 electrically connected to the second conductive structure and the ground connection point on the second frame 12 electrically connected to the third conductive structure divide the second frame into the second radiation branch 121, the second frame body 122 and the third radiation branch 123 in sequence.

[0043] In some embodiments, the second radiating branches 121 , the second frame body 122 , and the third radiating branches 123 may be an integrated structure to enhance the structural stability of the second frame 12 .

[0044] The second conductive structure and the third conductive structure may be conductive structures such as springs or connecting ribs for electrically connecting the second frame 12 and the grounding structure of the electronic device.

[0045] For example, when the second frame 12 is an outer frame of a metal middle frame, the second conductive structure and the third conductive structure may be connecting ribs for connecting the outer frame and the inner frame.

[0046] It is understandable that due to the configuration of the second and third conductive structures, it is difficult for the energy of the first antenna to be coupled to the side where the third frame 13 is located through the second frame 12. However, by coupling the first radiating branch 111 with the grounded metal decorative ring 21, the first antenna can also couple energy in the area where the metal decorative ring 21 is located, providing an energy transmission channel. The metal decorative ring 21 can also be used to couple the energy excited by the first radiating branch 111 to the other side of the electronic device. Even if the energy excited by the first radiating branch 111 can be coupled to the side where the third antenna is located, the spatial coverage of the first antenna's directional pattern is improved, thereby significantly reducing the spatial signal blind spot that exists when the antenna is operating.

[0047] Furthermore, by adjusting the grounding method of the metal decorative ring 21, the resonance characteristics and field distribution characteristics of the metal decorative ring 21 can be adjusted, so that the metal decorative ring 21 can change the mode current weight ratio and field distribution characteristics of the first antenna coupled to it, thereby achieving the purpose of improving the spatial coverage of the directional pattern of the first antenna.

[0048] Optionally, the camera module 20 further includes a camera 22 , and the metal decorative ring 21 is electrically connected to a metal housing of the camera 22 .

[0049] In this embodiment, by electrically connecting the metal decorative ring 21 to the metal housing of the camera 22 and adjusting the grounding connection mode of the metal decorative ring 21 , the spatial coverage effect of the directional pattern of the first antenna can be further improved.

[0050] Moreover, by changing the grounding method of the metal decorative ring 21, the resonance characteristics and field distribution characteristics of the metal decorative ring 21 can also be changed, so that the energy coming out of the first radiation branch 111 can be coupled to the metal decorative ring 21. The metal decorative ring 21 can also be used as an energy transmission channel to couple the first radiation branch 111 to the other side of the electronic device, thereby achieving the purpose of improving the spatial coverage of the radiation pattern of the first antenna, and can also greatly enhance the coupling of the central metal structure of the electronic device.

[0051] It should be noted that when the metal decorative ring 21 is electrically connected to the metal housing of the camera 22 , the energy coupling effect of the metal decorative ring 21 is stronger than the energy coupling effect when the metal decorative ring 21 is not electrically connected to the metal housing of the camera 22 .

[0052] In the process of adjusting the grounding method of the metal decorative ring 21, not only the number of grounding connection points of the metal decorative ring 21 can be adjusted, but also the position of the grounding connection points of the metal decorative ring 21 can be adjusted; in addition, the number and grounding position of the metal decorative ring 21 can be adjusted based on the size and shape of the metal decorative ring 21, so as to maximize the spatial coverage effect of the directional pattern of the first antenna.

[0053] Optionally, the electronic device further includes a device body 40 , a plurality of grounding points are provided on the metal decorative ring 21 , and the metal decorative ring 21 is electrically connected to a grounding structure of the device body 40 through the plurality of grounding points.

[0054] The above-mentioned multiple grounding points can be distributed based on the number of cameras in the camera module 20. For example, when the camera module 20 is provided with two rows of cameras along the length direction of the electronic device, three grounding points can be set on the metal decorative ring 21, and the three grounding points are separated in sequence by the two rows of cameras. That is, by distributing the three grounding points at intervals along the length direction of the electronic device, the purpose of adjusting the resonance characteristics of the metal decorative ring 21 can be achieved.

[0055] like Figure 1 As shown, the three grounding points can be three black triangles on the metal decorative ring 21 separated by two rows of cameras, which are used to achieve electrical connection between the metal decorative ring 21 and the grounding structure of the device body 40.

[0056] In some embodiments, the electronic device may further include a conductive steel sheet, which may be disposed between the metal decorative ring 21 and the device body 40, and the metal decorative ring 21 may be electrically connected to the conductive steel sheet through multiple grounding points, and the conductive steel sheet may be electrically connected to the grounding structure of the device body 40 through conductive structures such as conductive springs, locking screws, or foam, for example, electrically connected to the grounding structure on the main board of the device body 40.

[0057] Among them, the above-mentioned device body 40 can be understood as other structures of the electronic device except for structures such as the metal frame 10 and the camera module 20, and the device body 40 can also include components such as a main board, a shell, and a display screen.

[0058] Optionally, the width of the gap between the first radiation branch 111 and the metal decorative ring 21 is less than 0.1λ1, where λ1 is the free space wavelength corresponding to the lowest frequency in the operating frequency band of the first antenna.

[0059] In this embodiment, by setting the width of the gap between the first radiating branch 111 and the metal decorative ring 21 to be less than 0.1λ1, the first radiating branch 111 can be better coupled with the metal decorative ring 21, thereby improving the stability of the radiation effect of the first antenna.

[0060] In some implementations, the width of the gap between the first radiation branch 111 and the metal decoration ring 21 can be set to 0.05λ1 or 0.04λ1.

[0061] Among them, the width of the gap between the first radiation branch 111 and the metal decorative ring 21 includes but is not limited to the above values, and the width of the gap between the first radiation branch 111 and the metal decorative ring 21 can be set based on actual needs and is not specifically limited here.

[0062] Optionally, the third frame 13 may be grounded via a fourth conductive structure, and a ground connection point on the third frame 13 electrically connected to the fourth conductive structure divides the third frame 13 into a fourth radiation branch 131 and a third frame body 132 .

[0063] In some embodiments, the fourth conductive structure may be a conductive structure such as a spring or a connecting rib for electrically connecting the third frame 13 and a ground structure of the electronic device.

[0064] For example, when the third frame 13 is an outer frame of a metal middle frame, the fourth conductive structure may be a connecting rib for connecting the outer frame and the inner frame.

[0065] The first feed source 31 is connected to the first radiation branch 111 ; the second feed source 32 is connected to the second radiation branch 121 ; the third feed source 33 is connected to the third radiation branch 123 , and the fourth radiation branch 131 is coupled to the fourth radiation branch 131 via the second slit 15 .

[0066] like Figure 1 As shown, the first conductive structure, the second conductive structure, the third conductive structure and the fourth conductive structure may be black block structures located between the metal frame 10 and the device body 40 , for achieving grounding of their respective corresponding radiation branches.

[0067] In some embodiments, the first slit 14 and the second slit 15 may be arranged symmetrically with respect to a vertical bisector of the second frame 12 of the electronic device to improve the overall appearance of the electronic device.

[0068] The first antenna may be an inverted-F antenna (IFA), which may operate in the WiFi 2.4 GHz frequency band, corresponding to a frequency range of 2.4 GHz to 2.5 GHz.

[0069] The third antenna can be located in a corner of the device where the second slit 15 is located. It can be an IFA + parasitic antenna. A loading tuning point can also be set on its parasitic radiating branch to enable the third antenna to operate in medium, low, and high frequency bands. The parasitic radiating branch of the third antenna is the fourth radiating branch 131, and the length of the fourth radiating branch 131 is similar to that of the first radiating branch 111.

[0070] The difference between the length of the first radiation branch 111 and the length of the fourth radiation branch 131 is generally no more than ±10%.

[0071] A second antenna is further provided on the second frame 12 . The second antenna can operate in the Global Positioning System (GPS) frequency band, the N78 frequency band, and the N79 frequency band, and the second antenna can also be an IFA antenna.

[0072] In some embodiments, the sum of the lengths of the second radiating branch 121, the second frame body 122, and the third radiating branch 123 is greater than 0.5λ2 and less than λ2, where λ2 is the dielectric wavelength in the electronic device corresponding to the lowest frequency in the working frequency band of the first antenna; the length of the second frame body 122 is less than 0.5λ2, the length of the second radiating branch 121 is greater than 0.25λ2 and less than 0.5λ2, and the length of the third radiating branch 123 is less than 0.25λ2.

[0073] Among them, the grounding method of the metal decorative ring 21 can be divided into a first grounding method and a second grounding method. The first grounding method indicates that the metal decorative ring 21 is electrically connected to the grounding structure of the device body 40 through multiple grounding points; the second grounding method indicates that on the basis of the first grounding method, the metal decorative ring 21 is also electrically connected to the metal shell of the camera 22.

[0074] See also Figure 2 , Figure 2 This is a schematic diagram of a curve showing how the directivity of the first antenna varies with frequency, as provided in an embodiment of the present application. Figure 2 As shown, the solid line curve is the directional frequency curve of the first antenna when the metal decorative ring 21 is in the first grounding mode; the dotted line curve is the directional frequency curve of the first antenna when the metal decorative ring 21 is in the second grounding mode. Figure 2 The comparison results of the curves shown show that in the WiFi 2.4G frequency band and when the metal decorative ring 21 is in the second grounding mode, the directivity of the first antenna is improved by 1.6-2dB, with lower directivity. That is, when the metal decorative ring 21 is in the second grounding mode, the first antenna has better omnidirectionality.

[0075] See also Figure 3 and Figure 4 , Figure 3 One of the schematic diagrams of the directivity CDF curve of the first antenna provided in an embodiment of the present application; Figure 4 This is a second schematic diagram of the directivity CDF curve of the first antenna provided in an embodiment of the present application. Specifically, Figure 3 The directivity CDF curve diagram shown is a directivity CDF curve diagram of the first antenna operating at a frequency of 2.4 GHz; Figure 4 The directivity CDF curve diagram shown is a directivity CDF curve diagram of the first antenna operating at a frequency of 2.5 GHz, and as shown in FIG. Figure 3 and Figure 4 The Cumulative Distribution Function (CDF) curve shows the cumulative distribution characteristics of the antenna pattern at various angles across the entire spherical space. The horizontal axis of the curve represents antenna directivity, and the vertical axis represents probability. A vertical axis of 0.2 represents a probability of 20%, and a point on the curve represents a probability less than the horizontal axis value. The higher the slope of the curve and the further to the right it moves, the more uniform the spatial response of the antenna pattern (a more circular pattern) and the better the coverage. The vertical axis of 0.2 corresponds to the horizontal axis value. A larger value indicates better coverage across the entire spherical space.

[0076] exist Figure 3 and Figure 4 In FIG, the solid line curve is the directivity CDF curve of the first antenna when the metal decorative ring 21 is in the first grounding mode; the dotted line curve is the directivity CDF curve of the first antenna when the metal decorative ring 21 is in the second grounding mode. Figure 3 and Figure 4 From the curve comparison results shown, it can be seen that the dotted curves of the first antenna at the two frequency points of 2.4 GHz and 2.5 GHz are steeper as a whole, that is, it has better omnidirectionality, and at the 0.2 (20%) probability point, when the metal decorative ring 21 is in the second grounding mode, the first antenna has better directivity and better overall spatial coverage, and has fewer blind spots for signals coming from different directions; and compared with the metal decorative ring 21 in the first grounding mode, the 2.4 GHz is improved by 3.6 dB and the 2.5 GHz is improved by 2.3 dB.

[0077] In addition, the electronic device also includes a steel sheet structure located below the metal decorative ring 21, which is tightly coupled to the metal decorative ring 21. Thus, the energy coupled and transmitted by the metal decorative ring 21 also has a strong field energy distribution on the steel sheet structure. In other words, in this application, coupling and energy transmission can be achieved by a large metal component within the electronic device close to the first antenna. This is not necessarily limited to a single metal component; multiple metal components can also be coupled and transmitted multiple times, so that the energy of the first antenna is distributed as widely and symmetrically as possible on the electronic device, achieving a more circular radiation pattern and better spatial coverage.

[0078] It should be noted that the third antenna can be coupled through a flexible printed circuit (FPC) antenna disposed inside the electronic device to achieve the purpose of improving its directivity.
