[0023] In related technologies, electronic devices need to support more and more frequency bands, but the overall layout is becoming more and more crowded. Electronic devices often use the frame as the antenna radiator and use slot antennas for antenna design.

[0024] However, due to the limitations of the appearance design and structural strength of the electronic device frame, there are certain restrictions on the number of antenna radiation gaps during the design of the electronic device.

[0030] In some embodiments, Figure 1 and Figure 2 As shown, the antenna assembly includes: a first antenna 10 and a second antenna 20 .

[0031] The first antenna 10 may include a first radiator 11 . The first radiator 11 may be a radiating element of an antenna assembly for converting an electrical signal into a radio signal. The first antenna 10 may radiate a first frequency band signal.

[0032] The second antenna 20 may include a second radiator 21 . The second radiator 21 may be a radiating element of the antenna assembly for converting an electrical signal into a radio signal. The second antenna 20 may radiate a second frequency band signal.

[0033] The first antenna 10 and the second antenna 20 may be arranged with a gap 60 therebetween, and the antenna assembly may be a slot antenna.

[0034] The matching circuit can be a circuit that enables the antenna to cover a specific frequency band through its own impedance design, thereby meeting the user's wireless communication needs.

[0035] Exemplarily, the matching circuit may include a first matching circuit 13 connected to the first antenna 10 and a second matching circuit 23 connected to the second antenna 20. The antenna assembly may include a ground point 14, a first feed source 12 and a second feed source 22, and the ground point 14 may be disposed on a side of the first feed source 12 on the first radiator 11 away from the slit 60.

[0036] The first feed source 12 may be connected to the first radiator 11 via a first matching circuit 13 , and the second feed source may be connected to the second radiator 21 via a second matching circuit 23 .

[0037] The matching circuit may be disposed on the second antenna 20 , and the matching circuit may include an adjustment module 30 .

[0038] When the first antenna 10 radiates a first frequency band signal, the second antenna 20 may serve as a parasitic branch of the first antenna 10 .

[0039] The impedance of the adjustment module 30 can match the second antenna 20 as a parasitic branch of the first antenna 10 to radiate the first frequency band signal, thereby strengthening the coupling between the second antenna 20 and the first antenna 10 radiating the first frequency band, so that the second antenna 20 can assist in radiating the first frequency band, thereby enhancing the radiation performance of the first frequency band of the antenna assembly.

[0040] The impedance matching of the adjustment module 30 can also enable the second antenna 20 to radiate the second frequency band signal, thereby enhancing the radiation performance of the second antenna 20 radiating the second frequency band.

[0041] The present invention improves the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10 by using the second antenna 20 that radiates the second frequency band signal as a parasitic branch of the first antenna 10 that radiates the first frequency band, and by providing an adjustment module 30 that matches the impedance of the first frequency band on the matching circuit of the second antenna 20, so that the coupling effect between the second antenna 20 and the first frequency band is better, the reuse of the antenna radiator is realized, the structural utilization rate of the antenna assembly is improved, the number of breaks 60 of the antenna assembly is reduced, and the structural strength of the antenna assembly is enhanced.

[0042] In some embodiments, the impedance of the adjustment module 30 may be configured to increase the equivalent length of the second antenna 20 .

[0043] By increasing the equivalent length of the second antenna 20, the second antenna 20 can be better matched with the first frequency band signal, and the coupling between the second antenna 20 and the first antenna 10 radiating the first frequency band can be strengthened, so that the second antenna 20 can serve as a parasitic branch of the first antenna 10 to assist in radiating the first frequency band, thereby enhancing the radiation performance of the first frequency band of the antenna assembly.

[0044] Exemplarily, the first frequency band signal may be a low frequency signal. When the second antenna 20 radiates the first frequency band signal, the adjustment module 30 may increase the capacitance of the second antenna 20 , thereby increasing the equivalent length of the second antenna 20 .

[0045] The present disclosure uses the second antenna 20 radiating the second frequency band signal as the parasitic branch of the first antenna 10 radiating the first frequency band, and provides an adjustment module 30 matching the impedance of the first frequency band on the matching circuit of the second antenna 20. The equivalent length of the second antenna 20 is increased, the radiation performance of the second antenna 20 as the parasitic branch of the first antenna 10 is improved, the coupling effect between the second antenna 20 and the first frequency band is better, the reuse of the antenna radiator is realized, the structural utilization rate of the antenna assembly is improved, the number of the fractures 60 of the antenna assembly is reduced, and the structural strength of the antenna assembly is strengthened.

[0046] In some embodiments, Figure 2 As shown, the regulating module 30 may include a first regulating element 301 and a second regulating element 302 connected in series.

[0047] One end of the second regulating element 302 may be connected to the first regulating element 301 , and the other end of the second regulating element 302 may be grounded.

[0048] One end of the first regulating element 301 may be connected to the matching circuit, and the other end of the first regulating element 301 may be connected to the second regulating element 302 .

[0049] The first adjustment element 301 and the second adjustment element 302 can be elements with different impedances. By changing the parameters of the first adjustment element 301 and the second adjustment element 302, the overall impedance of the adjustment module 30 can be changed, so that the impedance matching of the adjustment module 30 can enable the first antenna 10 to radiate the second frequency band signal, thereby enhancing the radiation performance of the first antenna 10 radiating the second frequency band.

[0050] The present invention improves the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10 by using the second antenna 20 that radiates the second frequency band signal as a parasitic branch of the first antenna 10 that radiates the first frequency band, and by providing an adjustment module 30 that matches the impedance of the first frequency band on the matching circuit of the second antenna 20, so that the coupling effect between the second antenna 20 and the first frequency band is better, the reuse of the antenna radiator is realized, the structural utilization rate of the antenna assembly is improved, the number of breaks 60 of the antenna assembly is reduced, and the structural strength of the antenna assembly is enhanced.

[0051] In some embodiments, Figure 2 As shown, the first frequency band may include a first sub-frequency band signal and a second sub-frequency band signal, and the first sub-frequency band signal and the second sub-frequency band signal may be models of different frequency bands.

[0052] The matching circuit may include a switch element, and the switch element may be connected to the adjustment module 30 .

[0053] The regulating module 30 includes a first regulating module 31 and a second regulating module 32 with different impedances. The switching element can switch different regulating modules 30 to a conducting state, that is, the switching element can turn on the first regulating module 31 or disconnect the first regulating module 31, and the switching element can turn on the second regulating module 32 or disconnect the second regulating module 32.

[0054] The first adjustment module 31 can match the impedance of the first sub-band signal, and the second adjustment module 32 can match the impedance of the second sub-band signal.

[0055] When the first antenna 10 radiates the first sub-band signal, the switch can turn on the first adjustment module 31, which can improve the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10, so that the second antenna 20 is better coupled with the first sub-band, thereby improving the performance of the second antenna 20 radiating the first sub-band.

[0056] When the first antenna 10 radiates the second sub-band signal, the switch can turn on the second adjustment module 32, which can improve the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10, so that the second antenna 20 is better coupled with the second sub-band, thereby improving the performance of the second antenna 20 radiating the second sub-band.

[0057] The present disclosure uses the second antenna 20 that radiates the second frequency band signal as a parasitic branch of the first antenna 10 that radiates the first frequency band, and provides a first adjustment module 31 that matches the impedance of the first sub-band and a second adjustment module 32 that matches the impedance of the second sub-band on the matching circuit of the second antenna 20, so that the adjustment module 30 can be matched with different radiation bands of the first antenna 10, thereby improving the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10 in multiple frequency bands, making the coupling effect of the second antenna 20 with the first sub-band and the second sub-band better, realizing the reuse of the antenna radiator, improving the structural utilization rate of the antenna assembly, reducing the number of breaks 60 of the antenna assembly, and strengthening the structural strength of the antenna assembly.

[0058] Figure 3 is a schematic structural diagram of another antenna assembly according to an exemplary embodiment.

[0059] In some embodiments, Figure 3 As shown, the switching element 50 may be a switch, and the first regulating module 31 may be connected to the matching circuit through the switch. When the switch is closed, the first regulating module 31 is turned on, and when the switch is opened, the first regulating element 301 is disconnected.

[0060] The second regulating module 32 can be connected to the matching circuit through a switch. When the switch is closed, the second regulating element 302 is turned on, and when the switch is opened, the second regulating module 32 is turned off.

[0061] In some embodiments, the first adjustment element 301 may be one or more of a capacitor, an inductor, and a resistor, and the second adjustment element 302 may be one or more of a capacitor, an inductor, and a resistor.

[0062] By changing the capacitance value of the capacitor, the inductance value of the inductor, the resistance value of the resistor, and the combination of the capacitor, inductor, and resistor, the adjustment module 30 can have different impedances and affect the capacitance and inductance of the antenna, thereby matching the antenna with the target radiation frequency band, improving the radiation efficiency of the antenna, and strengthening the signal radiation capability of the antenna assembly.

[0063] In some embodiments, the first frequency band may include a first sub-frequency band signal and a second sub-frequency band signal, and the first sub-frequency band signal and the second sub-frequency band signal may be models of different frequency bands.

[0064] The first adjustment element 301 may have a first state and a second state, and an impedance value of the first adjustment element 301 in the first state is different from an impedance value of the first adjustment element 301 in the second state.

[0065] When the first regulating element 301 is in the first state, the regulating module 30 can match the impedance of the first sub-band signal; when the first regulating element 301 is in the second state, the regulating module 30 can match the impedance of the second sub-band signal.

[0066] Among them, when the first antenna 10 radiates the first sub-frequency band signal, the first adjustment element 301 can be in the first state, which can improve the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10, so that the second antenna 20 is better coupled with the first sub-frequency band, thereby improving the performance of the second antenna 20 radiating the first sub-frequency band.

[0067] When the first antenna 10 radiates the second sub-band signal, the first adjustment element 301 can be in the second state, which can improve the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10, so that the second antenna 20 is better coupled with the second sub-band, thereby improving the performance of the second antenna 20 radiating the second sub-band.

[0068] Exemplarily, the first adjustment element 301 may include an adjustable capacitor, and the first adjustment element 301 may be switched between the first state and the second state by changing the capacitance value of the adjustable capacitor.

[0069] The present disclosure uses the second antenna 20 that radiates the second frequency band signal as a parasitic branch of the first antenna 10 that radiates the first frequency band, and provides an adjustment module 30 in which the first adjustment element 301 that matches the impedance of the first sub-band is in a first state and an adjustment module 30 in which the first adjustment element 301 that matches the impedance of the second sub-band is in a second state on the matching circuit of the second antenna 20, so that the adjustment module 30 can be matched with different radiation bands of the first antenna 10, thereby improving the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10 in multiple frequency bands, and making the coupling effect of the second antenna 20 with the first sub-band and the second sub-band better, realizing the reuse of the antenna radiator, improving the structural utilization rate of the antenna assembly, reducing the number of the breaks 60 of the antenna assembly, and strengthening the structural strength of the antenna assembly.

[0070] In some embodiments, Figure 2 As shown, the second frequency band may include a third sub-frequency band signal and a fourth sub-frequency band signal, and the third sub-frequency band signal and the fourth sub-frequency band signal may be models of different frequency bands.

[0071] The second adjustment element 302 may have a third state and a fourth state, and an impedance value of the second adjustment element 302 in the third state is different from an impedance value of the second adjustment element 302 in the fourth state.

[0072] When the second adjustment element 302 is in the third state, the adjustment module 30 can match the impedance of the third sub-band signal; when the second adjustment element 302 is in the fourth state, the adjustment module 30 can match the impedance of the fourth sub-band signal.

[0073] When the second antenna 20 radiates the third sub-band signal, the second adjustment element 302 can be in the third state, which can improve the radiation performance of the second antenna 20, so that the second antenna 20 is better coupled with the third sub-band, thereby improving the performance of the second antenna 20 radiating the third sub-band.

[0074] When the first antenna 10 radiates the fourth sub-band signal, the second adjustment element 302 can be in the fourth state, which can improve the radiation performance of the second antenna 20, so that the second antenna 20 is better coupled with the fourth sub-band, thereby improving the performance of the second antenna 20 in radiating the fourth sub-band.

[0075] Exemplarily, the second adjustment element 302 may include an adjustable inductor, and the second adjustment element 302 may be switched between the third state and the fourth state by changing the inductance value of the adjustable inductor.

[0076] The present disclosure provides an adjustment module 30 in which a second adjustment element 302 is in a third state and an adjustment module 30 in which a second adjustment element 302 is in a fourth state and an impedance matching circuit of the second antenna 20, so that the adjustment module 30 can be matched with different radiation bands of the second antenna 20, thereby improving the radiation performance of the second antenna 20 in multiple frequency bands, making the coupling effect of the second antenna 20 with the third sub-band and the fourth sub-band better, and improving the radiation performance of the antenna assembly.

[0077] In some embodiments, the first frequency band may include a global positioning frequency band signal and a 2.4G frequency band signal, and the second frequency band may include a 5G frequency band signal and an N78 frequency band signal.

[0078] In some embodiments, the impedance value of the first adjustment element 301 is 1 picofarad to 6 picofarads, and the impedance value of the second adjustment element 302 is 1 nanohenry to 6 nanohenry.

[0079] Exemplarily, when the first frequency band may include global positioning band signals and 2.4G band signals, and the second frequency band may include 5G band signals and N78 band signals, the impedance value of the first adjustment element 301 may be 1.8 picofarads, and the impedance value of the second adjustment element 302 may be 6.2 nanohenries.

[0080] In some embodiments, the second frequency band can be higher than the first frequency band. The antenna assembly includes a filter circuit 70. The filter circuit 70 can be set on the first antenna 10 or the second antenna 20. The filter circuit 70 can isolate the resonance of the second frequency band, thereby reducing the coupling degree of the second frequency band signal to the first antenna 10, reducing the interference of the second frequency band to the first antenna 10, and filtering the resonant signal of the second frequency band signal, thereby improving the radiation effect of the first antenna 10.

[0081] In some embodiments, the adjustment module 30 can be a capacitor-inductor circuit, the first frequency band signal can be a low-frequency signal, and the second frequency band signal can be a high-frequency signal. The capacitor-inductor circuit is equivalent to an inductor for the radiator of the high-frequency signal and is equivalent to a capacitor for the radiator of the low-frequency signal, so that the adjustment module 30 can increase the equivalent length of the radiator that radiates the low-frequency signal. For example, the equivalent length of the second antenna 20 as a parasitic branch of the first antenna 10 can be increased, so that the coupling effect of the second antenna 20 on the low-frequency signal is better.

[0082] Figure 4 The figure is a diagram of antenna radiation efficiency of an antenna assembly according to an exemplary embodiment.

[0083] like Figure 4 As shown, curve 1 is a radiation effect curve of the first antenna 10 with the adjustment module 30, curve 2 is a radiation effect curve of the first antenna 10 without the adjustment module 30, curve 3 is a system effect curve of the first antenna 10 with the adjustment module 30, and curve 4 is a system effect curve of the first antenna 10 without the adjustment module 30. The impedance value of the first adjustment element 301 may be 1.8 pF, and the impedance value of the second adjustment element 302 may be 6.2 nH.

[0084] Combining Curve 1 and Curve 2 as well as Curve 3 and Curve 4, it can be seen that the adjustment module 30 can improve the antenna efficiency from the 2.3 GHz band to the 3 GHz band.

[0085] Based on the same concept, an embodiment of the present disclosure also provides an electronic device.

[0086] The electronic device may be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a message transceiver device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, and a wearable device such as a watch or a bracelet, and may be any electronic device having an antenna assembly. In the following description, a mobile phone is used as an example, but the present disclosure is not limited thereto.

[0087] In some embodiments, the electronic device may include an antenna assembly, and the antenna assembly may be constructed as a slot antenna. The slot antenna may use the middle frame of the electronic device as the radiator of the first antenna 10, thereby avoiding the metal shielding effect of the middle frame of the electronic device on the antenna assembly, and realizing that at least a portion of the middle frame can be metal while also ensuring that the antenna assembly can normally receive external wireless signal information or transmit wireless signal information to the outside world. In terms of design, the slot antenna is easy to control the amplitude distribution within the antenna aperture plane, has a high aperture surface utilization rate, a small size, a light weight, and can achieve low or extremely low side lobes. At the same time, the slot antenna also has the advantages of a strong structure, simple and compact, easy processing, economical cost, convenient feeding, simple installation, concealability, and decoratability.

[0088] The present invention improves the radiation performance of the second antenna 20 as a parasitic branch of the first antenna 10 by using the second antenna 20 that radiates the second frequency band signal as a parasitic branch of the first antenna 10 that radiates the first frequency band, and by providing an adjustment module 30 that matches the impedance of the first frequency band on the matching circuit of the second antenna 20, so that the coupling effect between the second antenna 20 and the first frequency band is better, the reuse of the antenna radiator is realized, the structural utilization rate of the antenna assembly is improved, the number of breaks 60 of the antenna assembly is reduced, and the structural strength of the antenna assembly is enhanced.
