[0007] wherein the isolation structure is provided with a first isolation slot, the first isolation slot being perpendicular to the slot antenna and connected to the first slot antenna and the second slot antenna, and / or the main body portion is provided with a second isolation slot, the second isolation slot being arranged in parallel to the slot antenna.

[0008] By arranging the first isolation slot and / or the second isolation slot in the main body portion, the current in different directions in the antenna assembly circuit is blocked, the resistance is improved, the impedance of the differential mode signal and / or the common mode signal is adjusted, and the overall isolation of the antenna assembly is improved.

[0009] In a possible implementation, the feeding structure includes at least two first isolation slots, each of the first isolation slots being located at opposite ends of the slot antenna and arranged symmetrically along the extension direction of the slot antenna.

[0010] By arranging the symmetric first isolation slots, the impedance of the differential mode signal of the same frequency point is adjusted, and the isolation of the antenna assembly is improved.

[0011] In a possible implementation, the second isolation groove is located between two first isolation grooves, and opposite ends of the second isolation groove are in communication with the adjacent first isolation grooves along the extension direction of the second isolation groove.

[0012] The second isolation groove is in communication with the adjacent first isolation grooves, so as to further enhance the isolation effect of the isolation structure, thereby improving the isolation degree of the antenna assembly.

[0013] In a possible implementation, the slot antenna is a symmetric structure, and the isolation structure includes two first isolation grooves, and the distance between the first isolation grooves and the symmetric axis of the slot antenna is 32 mm to 40 mm.

[0014] The design is used to adjust the differential mode signal impedance at the frequency point of 2.45 GHz.

[0015] In a possible implementation, the slot antenna is a symmetric structure, and the isolation structure includes two first isolation grooves, and the distance between the first isolation grooves and the symmetric axis of the slot antenna is 8 mm to 12 mm.

[0016] The design is used to adjust the differential mode signal impedance at the frequency point of 5.5 GHz.

[0017] In a possible implementation, the first slot antenna and the second slot antenna are symmetric about the extension direction of the second isolation groove.

[0018] The second isolation groove is located at the middle position between the first slot antenna and the second slot antenna, so as to improve the isolation effect of the second isolation groove, thereby improving the isolation degree of the entire antenna assembly.

[0019] In a possible implementation, the first isolation groove is in communication with the first slot antenna and the second slot antenna along the width direction of the antenna assembly.

[0020] The first isolation groove is in communication with the first slot antenna and the second slot antenna, so as to further block the current of the main body part, thereby facilitating the adjustment of the impedance of the differential mode signal at the frequency point, and improving the isolation degree of the antenna assembly.

[0021] In a possible implementation, the slot antenna is a symmetric structure, and the slot antenna includes a first main body part and a second main body part, and the first main body part and the second main body part are located on opposite sides of a symmetric axis.

[0022] The feed assembly is located on the first main body part, and the isolation structure is located on the second main body part.

[0024] In a possible implementation, the isolation structure comprises two first isolation slots, the first isolation slots are arranged at intervals, and opposite ends of the second isolation slot are in communication with the first isolation slots, respectively. The antenna assembly further comprises a first capacitor, which is electrically connected to the main body on opposite sides of the second isolation slot in the extension direction of the second isolation slot.

[0025] Through such a design, the first isolation slot can simultaneously adjust the differential mode signal impedance of 2.45 GHz and 5.5 GHz frequency points, the second isolation slot adjusts the common mode signal impedance, and the first capacitor is used to enhance the electric field coupling and improve the signal quality.

[0026] In a possible implementation, the antenna assembly further comprises a second capacitor and a third capacitor, the first feed component is electrically connected to the second capacitor, and the second feed component is electrically connected to the third capacitor.

[0027] In this way, the antenna assembly is capacitively loaded, the resonant frequency is reduced, and the size of the slot antenna is further reduced.

[0028] In a possible implementation, the isolation structure comprises one second isolation slot and one first isolation slot, the second isolation slot is in communication with the first isolation slot, and part of the second isolation slot exceeds the symmetry axis in the length direction of the antenna assembly.

[0029] When the antenna assembly is of this structure, the isolation degree of the antenna assembly at the 5.5 GHz frequency point is good, and therefore, only one first isolation slot can be arranged to adjust the impedance of the differential mode signal at the 2.45 GHz frequency point. The second isolation slot can exceed the symmetry axis to better block the current, thereby adjusting the impedance of the common mode signal and improving the overall isolation degree of the antenna assembly, which conforms to the actual use requirements.

[0030] In a possible implementation, the distance between the second isolation slot and the first slot antenna is 10-13 mm.

[0031] Through such a design, the second isolation slot can block the current to adjust the impedance of the common mode signal and improve the isolation degree of the antenna assembly.

[0032] In a possible implementation, the antenna assembly further comprises a support portion, which is located on one side of the main body and connected to the main body in the thickness direction of the antenna assembly.

[0033] By setting the support part, the main body part can be supported, the structural strength of the antenna assembly is improved, and the possibility of deformation of the antenna assembly under pressure is reduced.

[0034] In a possible implementation, the material of at least part of the support part is FR4.

[0035] By setting the FR4 material, the frequency of the electromagnetic wave can be reduced. The dielectric constant of FR4 is 4.4, and the wavelength of the electromagnetic wave is reduced when propagating therein, so that the working frequency is increased. Therefore, under the same working frequency of the electromagnetic wave, the addition of the medium FR4 can be beneficial to reduce the size of the slot antenna, thereby facilitating the miniaturization of the antenna assembly, so as to facilitate the application of the antenna assembly to electronic devices such as mobile phones, tablet computers, notebook computers, and more in line with actual use requirements.

[0061] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0062] With the development of technology, electronic devices such as mobile phones, tablets, and laptops have become common communication tools for people. Since electronic devices need to support multi-band communication, and with the miniaturization of electronic devices, the distance between antennas is becoming closer and closer, resulting in poorer isolation of the antennas, which affects the signals of each frequency band, resulting in low signal quality, affecting the reception and transmission of signals by the antenna assembly, and thus leading to a decline in user experience.

[0063] In view of this, the embodiment of the present application provides an antenna assembly and an electronic device, for improving the isolation of the antenna assembly.

[0064] As shown in Figure 1 The embodiment of the present application provides an antenna assembly, wherein the antenna assembly comprises a main body part 1 and a feed assembly 2. The main body part 1 is provided with a slot antenna, which can comprise a first slot antenna 11 and a second slot antenna 12 arranged parallel to each other, and the lengths of the first slot antenna 11 and the second slot antenna 12 are consistent or only have a small difference. The feed assembly 2 comprises a first feed part 21 and a second feed part 22, the first feed part 21 is electrically connected with the main body part 1 on the opposite sides of the first slot antenna 11, and the second feed part 22 is electrically connected with the main body part 1 on the opposite sides of the second slot antenna 12, the feed assembly 2 is used to transmit electromagnetic waves from a closed transmission line system to the port of the antenna, and then radiate to the free space by using the antenna. Specifically, it can be the opposite sides of the length direction of the slot antenna. An isolation structure is arranged between the first slot antenna 11 and the second slot antenna 12, for improving the isolation of the antenna assembly, specifically, the isolation structure can comprise a first isolation slot 13 and / or a second isolation slot 14. The first isolation slot 13 is arranged along the direction perpendicular to the slot antenna, and the opposite ends of the first isolation slot 13 can be in communication with the first slot antenna 11 and the second slot antenna 12 respectively, and the second isolation slot 14 is arranged along the direction parallel to the slot antenna.

[0065] Here it needs to be explained that the parallel and perpendicular involved in the embodiment of the present application are not absolute sense of perpendicular, but are approximately in the state of parallel and perpendicular, and in actual processing, there can be a certain included angle due to the influence of error and other factors.

[0066] Specifically, as shown in Figure 1 The slot antenna extends along the length direction of the antenna assembly, the first isolation slot 13 extends along the width direction of the antenna assembly, and the second isolation slot 14 extends along the length direction of the antenna assembly. According to Ohm's law, when the voltage of the circuit of the antenna assembly is constant, with the change of the current size in the circuit, the resistance size in the circuit will also change, by arranging the first isolation slot 13 to hinder the current transmission along the length direction of the antenna assembly, when the current in this direction decreases, the corresponding resistance will increase, thereby the differential mode signal impedance of the antenna assembly can be improved. Similarly, the second isolation slot 14 can hinder the current transmission along the width direction of the antenna assembly, thereby increasing the corresponding resistance, so as to adjust the common mode signal impedance of the antenna assembly, so as to improve the isolation of the antenna.

[0067] By setting the first isolation groove 13 and the second isolation groove 14, the impedance of the differential mode signal and the common mode signal can be adjusted respectively, thereby improving the isolation degree of the antenna assembly. Specifically, the main body part 1 of the antenna assembly can be provided with the first isolation groove 13 and the second isolation groove 14 at the same time to adjust the impedance of the differential mode signal and the common mode signal at the same time, so that the differential mode signal and the common mode signal are in the same range, thereby further improving the isolation degree of the antenna assembly as a whole, thereby facilitating the improvement of the signal quality of the antenna assembly and reducing the possibility of mutual interference between different signals.

[0068] As shown in Figure 1 , the isolation structure can include a plurality of first isolation grooves 13, which can be arranged at opposite ends of the slot antenna along the extension direction of the slot antenna and symmetrically arranged about the slot antenna, as shown in Figure 1 , the dotted line in the figure represents the axis of symmetry of the slot antenna, and the first isolation grooves 13 are symmetrically arranged about the axis. Specifically, a group of first isolation grooves 13 symmetrically arranged about the axis are used to adjust the impedance of the differential mode signal at the same frequency point. For example, along the length direction of the antenna assembly, the two first isolation grooves 13 located at the outermost sides can be used to adjust the differential mode signal impedance at the frequency point of 2.45 GHz, and the two first isolation grooves 13 located at the middle position can be used to adjust the differential mode signal impedance at the frequency point of 5.5 GHz. The positions of the first isolation grooves 13 can be adjusted according to the frequency point to adjust the differential mode signal impedance at the corresponding frequency point.

[0069] As shown in Figure 1 , in a possible implementation, the second isolation groove 14 can be in communication with the first isolation groove 13.

[0070] Through actual experiments and detection, by making the first isolation groove 13 in communication with the second isolation groove 14, the overall isolation degree of the antenna assembly can be further improved, which is more in line with the actual use requirements.

[0071] As shown in Figure 1 , in a possible implementation, along the length direction of the antenna assembly, the lengths of the first slot antenna 11 and the second slot antenna 12 can be 90-100 mm respectively, and the widths can be 3 mm. The first feeding component 21 and the second feeding component 22 are respectively located at the middle positions of the first slot antenna 11 and the second slot antenna 12. The antenna assembly can adjust the impedances at the frequency points of 2.45 GHz and 5.5 GHz, Figure 1The dotted line in the diagram represents the axis of symmetry of the antenna assembly. Both the slot antenna and the isolation structure can be symmetrically arranged about this axis. The first isolation slot 13, used for adjusting the differential-mode signal at the 2.45 GHz frequency, can be positioned 32 mm to 40 mm from this axis of symmetry, with a width of 1 mm to 2 mm. The first isolation slot 13, used for adjusting the differential-mode signal at the 5.5 GHz frequency, can be positioned 8 mm to 12 mm from this axis of symmetry, with a width of 3 mm to 5 mm. The distance between the first slot antenna 11 and the second slot antenna 12 can be 23 mm to 27 mm. The first isolation slot 13 can communicate with both the first slot antenna 11 and the second slot antenna 12, meaning the dimension of the first isolation slot 13 along the width direction of the antenna assembly can be 23 mm to 27 mm. The second isolation slot 14 is located between the first slot antenna 11 and the second slot antenna 12, and the first slot antenna 11 and the second slot antenna 12 can be symmetrically arranged about the second isolation slot 14. The length of the second isolation slot 14 can be 16 mm to 24 mm. Along the width direction of the antenna assembly, the distance between the second isolation slot 14 and the first slot antenna 11 and / or the second slot antenna 12 can be 10 mm to 13 mm. The width of the second isolation slot 14 can be 1 mm to 2 mm.

[0072] The width of the first isolation slot 13 can be adjusted according to different frequency points, for example, when Figure 1 In the embodiment shown, when the adjusted frequency points are 2.45GHz and 6GHz or 2.45GHz and 7.5GHz, the width of the first isolation slot 13 connected to the second isolation slot 14 in the figure will change accordingly to adjust the ratio between the two frequency points.

[0073] It should be noted that the data ranges involved in the embodiments of this application, including the data ranges mentioned below, are all obtained through actual experiments and measurements, and the two endpoints of the upper and lower limits of each data range are within the range.

[0074] Figure 2 The diagram shown illustrates the isolation of a conventional dual-slot antenna. Figure 3 For this application Figure 1 The diagram illustrates the isolation of the antenna assembly in this embodiment. It is clear from the diagram that the isolation of the solution provided in this application is superior to that of a conventional dual-slot antenna without an isolation structure. The numbers on the broken lines in the diagram represent selected sample points and the operating frequencies of the dual-band antenna. For example, points 1 and 2 represent the first frequency band, point 5 represents the first preset frequency, points 3 and 4 represent the second frequency band, and point 6 represents the second preset frequency. Figure 2 In the diagram, the first preset frequency is 2.45 GHz, and the second preset frequency is 5.5 GHz. That is, the positions marked in the isolation diagrams are the preset frequency points, i.e., the frequency points where the isolation needs to be adjusted.

[0075] likeFigure 4 As shown, in one possible implementation, the length of the slot antenna can be 0.5 times the wavelength. Specifically, the slot antenna can be symmetrically arranged about the dotted line in the figure, which extends along the width direction of the antenna assembly, thus representing the symmetry of the slot antenna. Along the length direction of the antenna assembly, this axis of symmetry divides the slot antenna into a first body section and a second body section, wherein the first feed component 21 and the second feed component 22 are located in the first body section, and the isolation structure is located in the second body section.

[0076] This design effectively reduces the size of the slot antenna, shortening its length from one wavelength to 0.5 wavelengths. This reduces the overall size of the antenna assembly, making it suitable for use in electronic devices such as mobile phones, tablets, and laptops. It also facilitates the miniaturization and thinning of electronic devices, better meeting practical usage needs.

[0077] like Figure 4 As shown, in one possible implementation, the antenna assembly may further include a first capacitor 3, which is electrically connected to the main body 1. Specifically, along the extending direction of the second isolation groove 14, the first capacitor 3 is electrically connected to the main body 1 on opposite sides of the second isolation groove 14.

[0078] Setting the first capacitor 3 can enhance the coupling of the electric field, thereby improving the signal quality. It can also further adjust the impedance of the common-mode signal to improve the isolation of the antenna assembly.

[0079] According to actual experiments, when the isolation structure and the power supply component are located on the same side of the axis of symmetry, that is, when the power supply component and the isolation structure are located in the first body part or the second body part at the same time, the improvement effect on the isolation of the antenna assembly is small. Therefore, in the embodiments of this application, the power supply component and the isolation structure are arranged on opposite sides of the axis of symmetry.

[0080] like Figure 4 As shown, in one possible implementation, the length of the slot antenna along the length direction of the antenna assembly can be 50 mm to 51 mm. The feed component can be positioned at a distance of 6.5 mm to 8.5 mm from the axis of symmetry. A first isolation section for adjusting the impedance of the differential-mode signal at the 5.5 GHz frequency point can be positioned at a distance of 1 mm to 2 mm from the axis of symmetry, and its width can be 2 mm to 2.5 mm. A second isolation section for adjusting the impedance of the differential-mode signal at the 2.45 GHz frequency point can be positioned at a distance of 19 mm to 21 mm from the axis of symmetry, and its width can be 2 mm. A second isolation slot 14 can be located between and communicate with the two first isolation slots 13, and its width can be 1 mm. The second isolation slot 14 is positioned at a distance of 10 mm to 13 mm from the first slot antenna 11.

[0081] Figure 5 For this application Figure 4 A schematic diagram of the isolation level of the provided embodiment.

[0082] like Figure 6 As shown, in one possible implementation, the antenna assembly may include a second capacitor 4 and a third capacitor 5. The first feed component 21 and the second capacitor 4 are electrically connected to form the first feed component 2, and the second feed component 22 and the third capacitor 5 are electrically connected to form the second feed component 2.

[0083] By capacitively loading the antenna components in this way, the resonant frequency is reduced, which helps to further reduce the size of the slot antenna. The size of the slot antenna can be shortened to 0.3 times the wavelength.

[0084] like Figure 6 As shown, in one possible implementation, when the size of the slot antenna is 0.3 times the wavelength, only one first isolation slot 13 and one second isolation slot 14 can be provided. The dotted line in the figure is the axis of symmetry of the slot antenna. The first feed assembly 2 and the second feed assembly 2 are located in the first body part, and the isolation structure part is located in the second body part. The second isolation slot 14 extends in the direction close to the feed assembly 2, and a part of the second isolation slot 14 can cross the axis of symmetry.

[0085] Based on the results of actual experiments, when the antenna assembly is Figure 6 With the structure shown, the antenna assembly exhibits good isolation at the 5.5GHz frequency point. Therefore, only one first isolation slot 13 needs to be set to adjust the impedance of the differential-mode signal at the 2.45GHz frequency point. The second isolation slot 14 can cross the axis of symmetry to better block current, thereby facilitating the adjustment of the impedance of the common-mode signal and further improving the overall isolation of the antenna assembly, which is more in line with actual usage requirements.

[0086] like Figure 6 As shown, in one possible implementation, the length of the slot antenna along the length direction of the antenna assembly can be 36 mm to 38 mm. The feed assembly 2 can be positioned at a distance of 4.5 mm to 5.5 mm from the axis of symmetry. The first isolation slot 13 can be positioned at a distance of 5 mm to 7 mm from the axis of symmetry and can be 1 mm wide. The distance between the second isolation slot 14 and the first slot antenna 11 is 10 mm to 13 mm, and the second isolation slot 14 can be 1 mm wide and 7 mm to 9 mm long.

[0087] Figure 7 For this application Figure 6 A schematic diagram of the isolation level of the provided embodiment.

[0088] like Figure 8As shown, in a possible implementation, the antenna assembly can further include a support part 6 located on one side of the main part 1 and connected with the main part 1 along the thickness direction of the antenna assembly, for supporting the main part 1 to improve the overall strength of the antenna assembly, thereby reducing the possibility of damage caused by deformation of the antenna assembly due to extrusion The possibility of damage caused by deformation due to extrusion is received.

[0089] In a possible implementation, the material of the support part 6 can be a resin material, for example, FR4, which can help to reduce the frequency of electromagnetic waves. The dielectric constant of FR4 is 4.4, and the wavelength of electromagnetic waves will decrease when propagating in it, so that the operating frequency is increased. Therefore, under the same operating frequency of electromagnetic waves, the addition of medium FR4 can help to reduce the size of the slot antenna, thereby facilitating the miniaturization of the antenna assembly, so as to facilitate the application of the antenna assembly to electronic devices such as mobile phones, tablets, and laptops, and to better meet the actual use requirements.

[0090] Based on the antenna assemblies provided in the above embodiments, the embodiments of the present application further provide an electronic device. The electronic device can be a mobile phone, a tablet computer, a laptop computer, etc. The electronic device can include the antenna assembly related to any of the above embodiments. Since the antenna assembly has the above technical effects, the electronic device including the antenna assembly also has corresponding technical effects, which will not be described here.

[0091] The embodiments of the present application provide an antenna assembly and an electronic device. The antenna assembly includes a main part 1 and a feed assembly 2. The main part 1 is provided with a first slot antenna 11 and a second slot antenna 12 and an isolation structure. The first feed part 21 and the second feed part 22 are respectively arranged in the first slot antenna 11 and the second slot antenna 12. The isolation structure can include a first isolation slot 13 perpendicular to the slot antenna and / or a second isolation slot 14 parallel to the slot antenna. The first isolation slot 13 is used to adjust the differential mode signal impedance, and the second isolation slot 14 is used to adjust the common mode signal impedance. By adjusting the differential mode signal impedance and / or the common mode signal impedance, the overall isolation of the antenna assembly is improved, thereby facilitating the improvement of the signal quality of the antenna, reducing the possibility of mutual interference between different signals, and better meeting the actual use requirements.
