[0042] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] An embodiment of the present application provides a communication device, which includes a first radiator and a second radiator arranged adjacent to each other and formed on the edge of a middle frame. The opposite ends of the first radiator and the second radiator respectively form a connection end of the first radiator and a connection end of the second radiator. The connection end of the first radiator is used to achieve grounding of the first radiator through a first grounding point, and the connection end of the second radiator is used to achieve grounding of the second radiator through a second grounding point, so as to enhance the anti-interference capability of the first radiator and the second radiator.

[0044] At the same time, the first grounding point and the second grounding point are far away from each other, thereby improving the isolation between the first radiator and the second radiator and ensuring the signal radiation reliability of the first radiator and the second radiator.

[0045] In some embodiments, reference Figure 1 , the present application provides a communication device, the communication device comprising:

[0046] A middle frame, the edges of which form adjacent first and second radiators 2 and 3;

[0047] One end of the first radiator 2 close to the second radiator 3 forms a first connection end, and one end of the second radiator 3 close to the first radiator 2 forms a second connection end;

[0048] The first connection end is grounded through a first grounding point 21 , and the second connection end is grounded through a second grounding point 31 . The first grounding point 21 and the second grounding point 31 are located on opposite sides of the grounding end surface 11 in a width direction.

[0049] In order to achieve the integration and concealment of antennas in communication terminals, the antenna radiator can be designed on the middle frame. By forming one or more antenna radiators on the middle frame, the communication terminal can support multiple frequency bands and improve the compatibility and flexibility of the communication terminal.

[0050] Specifically, antenna radiators other than the first radiator 2 and the second radiator 3 may be formed on the middle frame, for example, multiple antenna radiators such as a third radiator and a fourth radiator may be formed on the middle frame to increase the frequency band of the radiated signal on the middle frame.

[0051] In this embodiment, a gap is formed between the first connection end of the first radiator 2 and the second connection end of the second radiator 3 to separate the first radiator 2 and the second radiator 3. On the basis of achieving the independence of the first radiator 2 and the second radiator 3, the integration of the antenna radiator formed on the middle frame is ensured.

[0052] See also Figure 1 and Figure 3 The first connection end is grounded to the ground end surface 11 or near the ground end surface 11 through the first grounding point 21, and the second connection end is grounded to the ground end surface 11 or near the ground end surface 11 through the second grounding point 31, that is, the first radiator 2 and the second radiator 3 are both arranged near the ground end surface 11.

[0053] Among them, the grounding end surface 11 can be a side surface on the grounding device, and the grounding device can be a device in the communication terminal that can be used as a reference ground in components such as the mainboard, mainboard bracket or battery cover; the first radiator 2 is grounded to the grounding device through the first grounding point 21, and the second radiator 3 is grounded to the grounding device through the second grounding point 31, which can enhance the anti-interference ability of the first radiator 2 and the second radiator 3.

[0054] In one embodiment, the grounding device has a height dimension, a length dimension, and a width dimension. For example, the height dimension of the grounding device may be Figure 1 The length of the grounding device can be its size in the Z direction. Figure 1 The width of the grounding device can be the size in the X direction. Figure 1 and the top surface of the grounding device forms a grounding end surface 11, and the grounding end surface 11 is located in the XOY plane.

[0055] In this embodiment, the first grounding point 21 is the current intensity point of the first radiator 2, and the second grounding point 31 is the current intensity point of the second radiator 3. There will be strong magnetic coupling between the first radiator 2 and the second radiator 3, which is likely to affect the isolation between the first radiator 2 and the second radiator 3.

[0056] In the communication device provided in the embodiment of the present application, the first grounding point 21 and the second grounding point 31 are located on opposite sides in the width direction of the grounding end surface 11, that is, the first grounding point 21 and the second grounding point 31 are separated on both sides of the grounding end surface 11, thereby achieving effective isolation of the first grounding point 21 and the second grounding point 31, reducing the coupling current between the first grounding point 21 and the second grounding point 31, and improving the decoupling effect of the first radiator 2 and the second radiator 3.

[0057] In one embodiment, the grounding end surface 11 has a length dimension and a width dimension, and the length dimension of the grounding end surface 11 is greater than the width dimension. The length dimension of the grounding end surface 11 can be a dimension in its length direction, such as Figure 2 As shown, the grounding end surface 11 is located in the XOY plane, and the length of the grounding end surface 11 can be Figure 2The width dimension of the ground end surface 11 may be the dimension in the width direction thereof, for example, the width dimension of the ground end surface 11 may be the dimension in the width direction thereof. Figure 2 The size in the Y direction.

[0058] The first radiator 2 and the second radiator 3 both extend along the X direction and are arranged adjacent to each other, and the first grounding point 21 for grounding the first radiator 2 and the second grounding point 31 for grounding the second radiator 3 are located on opposite sides of the ground end surface 11 in the Y direction. By increasing the distance between the first grounding point 21 and the second grounding point 31, the magnetic coupling between the first radiator 2 and the second radiator 3 is reduced, thereby improving the isolation between the first radiator 2 and the second radiator 3 and ensuring the signal radiation reliability of the first radiator 2 and the second radiator 3.

[0059] In some embodiments, the operating frequency bands of the first radiator 2 and the second radiator 3 at least partially overlap.

[0060] In this embodiment, the first radiator 2 and the second radiator 3 can both operate in a set frequency band, which can be a low frequency band, a medium frequency band, a medium-high frequency band or a high frequency band. For example, the first radiator 2 and the second radiator 3 both operate in a low frequency band, or the first radiator 2 and the second radiator 3 both operate in a medium frequency band.

[0061] It is also possible that the frequency bands in which the first radiator 2 and the second radiator 3 operate are partially the same, for example, the first radiator 2 operates in the medium and low frequency bands, and the second radiator 3 operates in the medium and high frequency bands. The first radiator 2 and the second radiator 3 operate in the same or similar frequency bands, which can more effectively utilize spectrum resources, but there will also be the problem of mutual interference between antennas in the same frequency band.

[0062] The embodiment of the present application reduces the magnetic coupling between the first radiator 2 and the second radiator 3 by increasing the distance between the first grounding point 21 and the second grounding point 31, thereby avoiding strong coupling between the electromagnetic radiation and reception between the adjacent first radiators 2 and the second radiator 3, improving the isolation between the first radiator 2 and the second radiator 3, ensuring the effective radiation efficiency of the antennas formed by the first radiator 2 and the second radiator 3, and maintaining the overall communication quality of the communication device.

[0063] Figure 4The isolation test curve between the first radiator 2 and the second radiator 3 in the embodiment of the present application (this patent 1) and the isolation test curve between the two radiators in the comparative example 1 are given. Both the comparative example 1 and the embodiment of the present application (this patent 1) include two radiators, and the ends of the two radiators close to each other form respective connection ends, and the two connection ends are grounded through corresponding grounding points respectively. The only difference between the comparative example 1 and the embodiment of the present application (this patent 1) is that the first connection end of the embodiment of the present application (this patent 1) is grounded through the first grounding point 21, and the second connection end is grounded through the second grounding point 31, and the first grounding point 21 and the second grounding point 31 are arranged relatively far apart on both sides of the grounding end surface 11, as shown in FIG. Figure 1 and Figure 3 As shown; in Comparative Example 1, the connection ends of the two radiators are grounded through the fifth grounding point 02 and the sixth grounding point 03 respectively. The fifth grounding point 02 and the sixth grounding point 03 are arranged opposite to each other in the extension direction of the two radiators, that is, the fifth grounding point 02 and the sixth grounding point 03 are arranged relatively close to each other on the same side of the first grounding end surface 01 (corresponding to the grounding end surface 11), as shown. Figure 8 and Figure 9 shown.

[0064] from Figure 4 It can be seen that compared with the comparative example 1, the isolation of the embodiment of the present application is -3.7dB ( Figure 4 Middle inverted triangle 1) optimized to -6db( Figure 4 Inverted triangle 2), and at 1.95Ghz ( Figure 4 The inverted triangle 3) generates a transmission zero point, thereby achieving the purpose of improving the isolation between the first radiator 2 and the second radiator 3.

[0065] In some embodiments, see Figure 1 and Figure 2 , the projection of the first grounding point 21 on the side where the second grounding point 31 is located is adjacent to the second grounding point 31.

[0066] In this embodiment, the first grounding point 21 and the second grounding point 31 can be located on both sides of the grounding end surface 11, for example, the first grounding point 21 can be located at Figure 2 On the lower side surface adjacent to the ground end surface 11, the second grounding point 31 can be located Figure 2 On the upper side surface adjacent to the ground end surface 11, the second grounding point 31 and the first grounding point 21 are spaced apart on the upper and lower sides of the ground end surface 11, and the projection of the first grounding point 21 on the upper side surface adjacent to the ground end surface 11 is adjacent to the second grounding point 31. For example, the distance between the projection of the first grounding point 21 on the upper side surface adjacent to the ground end surface 11 and the second grounding point 31 is equal to or close to the distance between the first radiator 2 and the second radiator 3, which can improve the compactness of the arrangement of the first radiator 2 and the second radiator 3 on the middle frame.

[0067] In some embodiments, see Figure 1 At least a portion of the first radiator 2 and at least a portion of the second radiator 3 are arranged parallel to the ground end surface 11 .

[0068] In this embodiment, the ground end surface 11 can extend along a first direction, which can be the length direction of the ground end surface 11. The portion of the first radiator 2 opposite to the ground end surface 11 is suspended on the ground end surface 11 along the first direction, and the portion of the second radiator 3 opposite to the ground end surface 11 is suspended on the ground end surface 11 along the first direction, so that at least a portion of the first radiator 2 and at least a portion of the second radiator 3 are arranged parallel to the ground end surface 11, which can weaken the interaction between the electric field and the magnetic field between the first radiator 2 and the second radiator 3, thereby reducing the possibility of mutual interference.

[0069] At the same time, the first grounding point 21 and the second grounding point 31 are arranged on opposite sides of the grounding end surface 11 in the second direction. The second direction can be the width direction of the grounding end surface 11. The second direction is perpendicular to the first direction, so as to improve the isolation between the first radiator 2 and the second radiator 3 while ensuring the radiation performance of the first radiator 2 and the second radiator 3.

[0070] In some embodiments, see Figures 1 to 3 The first radiator 2 includes a first branch 201, and the second radiator 3 includes a second branch 301. An end of the first branch 201 close to the second branch 301 forms a first connecting end, and an end of the first branch 201 away from the second branch 301 forms a first free end.

[0071] The first branch 201 includes a first feeding point 22 , which is connected to a first feed source to excite the first branch 201 to resonate.

[0072] In this embodiment, the first connection end serves as a reference ground for the first branch 201, which helps the first radiator 2 to form a stable electric field distribution, thereby improving the radiation efficiency of the first radiator 2; the first free end allows electromagnetic waves to propagate freely in space, reducing the energy loss of the first radiator 2 caused by reflection or scattering.

[0073] At the same time, the grounding point of the first radiator 2 and the grounding point of the second radiator 3 are located on opposite sides in the width direction of the grounding end surface 11, and the grounding end surface 11 is provided with a first feeding module; the first branch 201 includes a first feeding point 22, and a first feed source is provided on the middle frame. The first feeding point 22 connects the first feeding module to the first feed source, and the first feed source is used to excite the first branch 201 to resonate in the set frequency band, which helps to concentrate energy within the set frequency band, reduce energy waste and scattering, and thus improve the radiation efficiency of the antenna formed by the first radiator 2.

[0074] In some embodiments, see Figures 1 to 3 , an end of the second branch 301 close to the first branch 201 forms a second connecting end, and an end of the second branch 301 away from the first branch 201 forms a second free end;

[0075] The second branch 301 includes a second feeding point 32 , which is connected to a second feed source to excite the second branch 301 to resonate.

[0076] In this embodiment, the second connection end serves as a reference ground for the second branch 301, which helps the second radiator 3 form a stable electric field distribution, thereby improving the radiation efficiency of the second radiator 3; the second free end allows electromagnetic waves to propagate freely in space, reducing the energy loss of the second radiator 3 caused by reflection or scattering.

[0077] At the same time, the grounding point of the first radiator 2 and the grounding point of the second radiator 3 are located on opposite sides in the width direction of the grounding end surface 11, and the grounding end surface 11 is provided with a second feeding module; the second branch 301 includes a second feeding point 32, and a second feed source is provided on the middle frame. The second feeding point 32 connects the second feeding module to the second feed source, and the second feed source is used to excite the second branch 301 to resonate in the set frequency band, which helps to concentrate energy within the set frequency band, reduce energy waste and scattering, and thus improve the radiation efficiency of the second radiator 3 to form an antenna.

[0078] In some embodiments, see Figure 5 and Figure 6 The first branch 201 and / or the second branch 301 are IFA antennas.

[0079] In this embodiment, the first branch 201 and the second branch 301 may both be IFA antennas (Inverted FAntenna). Figure 7 The isolation test curve between the first branch 201 and the second branch 301 in the embodiment of the present application (patent 2) and the isolation test curve between the two radiators in comparative example 2 are given. Comparative example 2 and the embodiment of the present application (patent 2) both include two IFA antennas, and the ends of the two IFA antennas close to each other form respective connection ends, and the two connection ends are grounded through corresponding grounding points respectively. The only difference between comparative example 2 and the embodiment of the present application (patent 2) is that the first branch 201 in the embodiment of the present application (patent 2) is grounded through the first grounding point 21, and the second branch 301 is grounded through the second grounding point 31, and the first grounding point 21 and the second grounding point 31 are placed relatively far apart on both sides of the grounding end surface 11, as shown in FIG. Figure 6As shown; in Comparative Example 2, the connection ends of the two IFA antennas are grounded through the seventh grounding point 05 and the eighth grounding point 06, respectively. The seventh grounding point 05 and the eighth grounding point 06 are arranged relatively close to each other in the extension direction of the two IFA antennas, that is, the seventh grounding point 05 and the eighth grounding point 06 are arranged relatively close to each other on the same side of the second grounding end surface 04 (corresponding to the grounding end surface 11), as shown in FIG. Figure 10 shown.

[0080] from Figure 7 It can be seen that compared with the comparative example 2, the intermediate frequency isolation between the first branch 201 and the second branch 301 of the present application is improved from -7.3dB ( Figure 7 Middle inverted triangle 1) optimized to -8.7db( Figure 7 Inverted triangle 2), WIFI 5G isolation from -3.9db ( Figure 7 Middle inverted triangle 3) optimized to -9.9db ( Figure 7 The middle inverted triangle 4) improves the isolation between the first branch node 201 and the second branch node 301 while maintaining the simplified structure of the first branch node 201 and the second branch node 301.

[0081] In some embodiments, see Figure 1 and Figure 2 The first radiator 2 includes a first parasitic branch 202, which is arranged on a side of the first branch 201 away from the second branch 301. The two ends of the first parasitic branch 202 respectively form a third connection end and a third free end. The third connection end is located at the end of the first parasitic branch 202 away from the first branch 201 and is grounded through a third grounding point 23. The third free end is located at the end of the first parasitic branch 202 close to the first branch 201 and is spaced opposite to the first free end.

[0082] In this embodiment, the third free end is spaced relative to the first free end to form a first parasitic gap 24 between the first parasitic branch 202 and the first branch 201. The gap size of the first parasitic gap 24 is related to the coupling effect between the first parasitic branch 202 and the first branch 201. By adjusting the size of the first parasitic gap 24, the first radiator 2 can maintain better resonance characteristics in a wider frequency band, thereby expanding the bandwidth of the first radiator 2.

[0083] In some embodiments, see Figure 1 and Figure 2The second radiator 3 includes a second parasitic branch 302, which is arranged on the side of the second branch 301 away from the first branch 201. The two ends of the second parasitic branch 302 respectively form a fourth connection end and a fourth free end. The fourth connection end is located at the end of the second parasitic branch 302 away from the second branch 301 and is grounded through the fourth grounding point 33. The fourth free end is located at the end of the second parasitic branch 302 close to the second branch 301 and is spaced opposite to the second free end.

[0084] In this embodiment, the fourth free end is spaced relative to the second free end to form a second parasitic gap 34 between the second parasitic branch 302 and the second branch 301. The gap size of the second parasitic gap 34 is related to the coupling effect between the second parasitic branch 302 and the second branch 301. By adjusting the size of the second parasitic gap 34, the second radiator 3 can maintain better resonance characteristics in a wider frequency band, thereby expanding the bandwidth of the second radiator 3.

[0085] In some embodiments, see Figure 1 , the communication device further includes a main body 1, the main body 1 carries a mainboard of the communication device, and the mainboard includes a grounding module;

[0086] The grounding end surface 11 is the side of the main body 1 facing the first radiator 2 and the second radiator 3 . The first connection end is connected to the grounding module through the first grounding point 21 , and the second connection end is connected to the grounding module through the second grounding point 31 .

[0087] In this embodiment, the main body 1 can be a component such as a motherboard bracket or a battery cover of a communication device. A mainboard is installed on the main body 1. The grounding module on the mainboard can establish a good grounding system so that the current can flow to the ground stably and safely, preventing static electricity accumulation from damaging the electronic components on the mainboard.

[0088] At the same time, the first connection end of the first radiator 2 is connected to the grounding module through the first grounding point 21, so that the electromagnetic radiation energy generated on the first radiator 2 can be introduced into the ground through the grounding module, thereby reducing the electromagnetic interference of the first radiator 2 to the surrounding environment; the second connection end of the second radiator 3 is connected to the grounding module through the second grounding point 31, and the electromagnetic radiation energy generated on the second radiator 3 is introduced into the ground through the grounding module, thereby reducing the electromagnetic interference of the second radiator 3 to the surrounding environment.

[0089] In one embodiment, the ground end surface 11 is the top surface of the main body 1, and the first connection end of the first radiator 2 is connected to the top surface or near the top surface of the main body 1 through the first grounding point 21. At the same time, the second connection end of the second radiator 3 is connected to the top surface or near the top surface of the main body 1 through the second grounding point 31, thereby optimizing the radiation pattern of the first radiator 2 and the second radiator 3 and reducing the energy loss of the first radiator 2 and the second radiator 3.

[0090] In some embodiments, the communication device further includes a mainboard, the mainboard including a grounding module;

[0091] The grounding end surface 11 is the side of the mainboard facing the first radiator 2 and the second radiator 3 . The first connection end is connected to the grounding module through the first grounding point 21 , and the second connection end is connected to the grounding module through the second grounding point 31 .

[0092] In this embodiment, the first radiator 2 and the second radiator 3 are arranged near the ground end surface 11 of the mainboard, and the ground end surface 11 can be the top surface of the mainboard, which helps to effectively guide the electromagnetic radiation energy generated by the first radiator 2 and the second radiator 3 to the ground module, thereby reducing the electromagnetic interference of the first radiator 2 and the second radiator 3 to the surrounding environment.

[0093] It is understandable that the communication device may specifically be a mobile phone, tablet, computer, vehicle or other device.

[0094] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention.
