[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] An embodiment of the present disclosure provides an antenna module, which is applied in a communication scenario. Figure 1 FIG. 1 is a schematic diagram of the structure of an antenna module according to an exemplary embodiment. Figure 1 As shown, the antenna module 100 includes:

[0041] The first radiating branch 101;

[0042] The second radiation branch 102 has a break F formed between it and the first radiation branch 101, and can be coupled with the first radiation branch 101;

[0043] A feeding point 103, located on the first radiation branch 101;

[0044] Among them, when the antenna module 100 transmits and receives wireless signals, the first radiating branch 101 has a grounding end A set away from the break F; the feeding point 103 is located between the grounding end A and the break F, and the first resonant frequency excited from the feeding point 103 to the break F position, the second resonant frequency excited from the grounding end A to the break F position, and the third resonant frequency excited from the second radiating branch 102 are all located within the working frequency band of the antenna module 101.

[0045] In the embodiments of the present disclosure, the antenna module can be applied to an electronic device, and the antenna module is used to send and receive wireless signals to realize communication interaction between the electronic device and other devices. For example, the electronic device includes a smart phone, and the other device includes a smart home device (such as a smart speaker). The smart phone can communicate with the smart speaker through the antenna module to control the smart speaker to output an audio signal; or, the electronic device and the other device both include smart phones, and the two smart phones make voice calls, video calls, or information transmissions through the antenna module.

[0046] The first radiation branch and the second radiation branch may be made of metal material and / or alloy material, which is not limited in the embodiments of the present disclosure.

[0047] In the embodiment of the present disclosure, there is an angle between the first radiation branch and the second radiation branch, and the angle is in the range of 0 to 180. For example, the angle may be 180, that is, the first radiation branch and the second radiation branch are located on the same straight line.

[0048] The shape of the first radiating branch and the shape of the second radiating branch can both be strip-shaped. Here, when the antenna module is applied to an electronic device, the conductive frame of the electronic device can be reused as the first radiating branch and the second radiating branch; or, the first radiating branch and the second radiating branch are distributed inside the conductive frame, and the embodiments of the present disclosure are not limited to this.

[0049] The length of the first radiation branch can be set according to the resonance frequency corresponding to the current mode formed by the first radiation branch. For example, the larger the resonance frequency corresponding to the current mode formed by the first radiation branch, the smaller the length of the corresponding first radiation branch can be set.

[0050] Of course, the length of the second radiation branch can also be set according to the resonance frequency corresponding to the current mode formed by the second radiation branch. For example, the larger the resonance frequency corresponding to the current mode formed by the second radiation branch, the smaller the length of the corresponding second radiation branch can be set.

[0051] The feed point is located on the first radiating branch. The feed point can transmit a first electrical signal to the first radiating branch to stimulate the first radiating branch to receive and transmit wireless signals; the feed point can also transmit a second electrical signal converted from the first radiating branch, and transmit the second electrical signal to the RF front-end component to realize signal reception and transmission of the antenna module.

[0052] The second radiation branch and the first radiation branch form a gap, the length of which can be set according to actual needs, and is not limited in the embodiment of the present disclosure. Here, the gap can be filled with insulating material to better separate the first radiation branch and the second radiation branch.

[0053] Here, the positions of the first radiation branch and the second radiation branch can be set according to actual conditions. Figure 1 As shown, the first radiation branch 101 and the first radiation branch 102 are arranged at intervals and distributed on the same straight line. In this way, the embodiment of the disclosure can reuse the frame on the same side of the electronic device as the first radiation branch and the second radiation branch to reduce the space occupied by the antenna module in the electronic device.

[0054] In the disclosed embodiment, when the antenna module is used in a smartphone, the end of the first radiating branch away from the break can extend to the first angle between two adjacent frames in the smartphone, and a first bending structure is formed to ensure the current path length of the first radiating branch. Of course, the end of the second radiating branch away from the break can also extend to the second angle between two adjacent frames in the smartphone, and a second bending structure is formed to ensure the current path length of the second radiating branch. The first angle and the second angle can be two adjacent angles in a smartphone.

[0055] The second radiation branch can be coupled with the first radiation branch. The coupling process may include: when the first radiation branch converts the alternating current into the alternating magnetic field, the second radiation branch can generate an alternating current under the action of the alternating magnetic field, and can generate an alternating magnetic field based on the alternating current, thereby enabling the second radiation branch to send and receive wireless signals.

[0056] In the disclosed embodiment, when the antenna module receives and transmits wireless signals, the first resonant frequency is excited from the feed point to the break position, the second resonant frequency is excited from the ground end to the break position, and the third resonant frequency is excited from the second radiation branch. Since the first resonant frequency, the second resonant frequency, and the third resonant frequency are all within the working frequency band of the antenna module, when the antenna module receives and transmits wireless signals, the first resonant frequency, the second resonant frequency, and the third resonant frequency are superimposed on each other to increase the working frequency band range of the antenna module and expand the antenna bandwidth of the antenna module.

[0057] For example, the operating frequency band of the expanded antenna module may be 700 MHz to 960 MHz, that is, by expanding the antenna bandwidth of the antenna module, full frequency band coverage of N5, N8, N20 and N28 can be achieved.

[0058] In the disclosed embodiment, the current mode corresponding to the first resonant frequency is a 1 / 4 wavelength current mode generated by the feeding point excitation; the current mode corresponding to the second resonant frequency is the intrinsic 1 / 4 wavelength mode generated by the first radiation branch; and the current mode corresponding to the third resonant frequency is a coupled 1 / 4 wavelength current mode generated by the coupling of the second radiation branch.

[0059] It should be noted that the first resonant frequency is greater than the second resonant frequency; the third resonant frequency, and the relationship between the first resonant frequency and the second resonant frequency can be set according to actual needs, and the embodiment of the present disclosure does not limit this. In the embodiment of the present disclosure, the first resonant frequency excited from the feed point to the break position, the second resonant frequency excited from the ground end to the break position, and the third resonant frequency excited by the second radiation branch are all within the working frequency band of the antenna module. In this way, the embodiment of the present disclosure does not need to be switched by the antenna switch, and the working frequency band range of the antenna module can be increased by superimposing the three resonant frequencies, thereby expanding the antenna bandwidth of the antenna module. In addition, the embodiment of the present disclosure receives and sends wireless signals through the first radiation branch and the second radiation branch, which can increase the radiation area of ​​the antenna module, thereby improving the efficiency of the antenna module in sending and receiving wireless signals.

[0060] For example, Figure 2 It is a simulation schematic diagram showing a comparison between an antenna module and a conventional antenna according to an exemplary embodiment. Figure 2 In the figure, the horizontal axis is the frequency in GHz; the vertical axis is the total efficiency or radiation efficiency in dB; the solid line 1 represents the radiation efficiency of the antenna module in the present disclosure; the solid line 2 represents the total efficiency of the antenna module in the present disclosure; the dotted line 3 represents the radiation efficiency of the existing antenna switch; the dotted line 4 represents the total efficiency of the existing antenna switch. Figure 2 It can be seen that when transmitting and receiving in the frequency range of 700MHz to 960MHz, the radiation efficiency of the antenna module of the present disclosure can be improved by 3dB, and the total efficiency of the antenna module of the present disclosure is greater than -12dB. In addition, when transmitting and receiving in the frequency range of 700MHz to 780MHz and 880MHz to 960MHz, the total efficiency of the antenna module of the present disclosure is improved by more than 2dB.

[0061] In some embodiments, Figure 1 As shown, the ratio of the distance from the feeding point to the ground terminal to the length of the first radiation branch is between 1 / 16 and 1 / 8.

[0062] It should be noted that the ratio can be any value between 1 / 16 and 1 / 8, and the embodiments of the present disclosure are not limited to this.

[0063] In the disclosed embodiment, by setting the ratio between 1 / 16 and 1 / 8, the first resonant frequency excited from the feed point to the position of the break can be within the working frequency band of the antenna module, so that the antenna bandwidth of the antenna module can be expanded. In addition, by setting the ratio between 1 / 16 and 1 / 8, the impact on the antenna performance can be minimized, thereby improving the antenna performance.

[0064] In some embodiments, Figure 1 As shown, the break F and the ground end A are arranged opposite to each other in the length direction of the first radiation branch 101, and the end of the second radiation branch 102 away from the break F is grounded.

[0065] like Figure 1 As shown, the end of the first radiation branch 101 at the position of the fracture F is the fracture end B. The ground end A and the fracture end B of the first radiation branch 101 are arranged along the length direction of the first radiation branch 101, not along the width direction of the first radiation branch 101. Therefore, the distance between the ground end A and the fracture end B is equal to the length of the first radiation branch 101.

[0066] In the disclosed embodiment, the grounding position and the break of the second radiating branch can also be arranged relative to each other in the length direction of the second radiating branch. The first radiating branch and the second radiating branch of the antenna module are arranged in the same straight line, so the length of the antenna module can be the sum of the length of the first radiating branch and the length of the second radiating branch.

[0067] In the disclosed embodiment, by grounding the end of the second radiating branch away from the break, it is easier to adjust the antenna module by adjusting the length of the second radiating branch, so that the antenna module can adapt to different bandwidth expansion scenarios.

[0068] In some embodiments, Figure 1 As shown, when the length of the second radiation branch 102 is less than or equal to the length of the first radiation branch 101, and greater than or equal to the distance from the feeding point 103 to the break F, the third resonant frequency is less than or equal to the first resonant frequency, and greater than or equal to the second resonant frequency.

[0069] In the disclosed embodiment, the length of the first radiation branch is λ1, the length of the second radiation branch is λ2, the distance from the feeding point to the grounding point is λ3, the distance from the feeding point to the break is λ1-λ3, the first resonant frequency corresponding to the current mode formed from the feeding point to the break is Fre1, the second resonant frequency corresponding to the current mode formed from the grounding end to the break is Fre2, and the third resonant frequency corresponding to the current mode formed by the coupling of the second radiation branch is Fre3. Here, since the distance from the grounding end to the break is greater than the distance from the feeding point to the break, Fre2 is less than Fre1.

[0070] In the case of λ1-λ3≤λ2≤λ1, Fre2≤Fre3≤Fre1. That is, by adjusting the length of the second radiation branch, the third resonant frequency can be located between the first resonant frequency and the second resonant frequency. That is, the embodiment of the present disclosure can change the magnitude relationship between the second resonant frequency and the first resonant frequency and the second resonant frequency, respectively, by adjusting the length of the second radiation branch. In this way, by flexibly adjusting the length of the second radiation branch, the antenna module can be adapted to different antenna bandwidth requirements.

[0071] In some embodiments, Figure 1 As shown, when the distance from the feeding point 103 to the break F is less than or equal to the length of the first radiation branch 101, and greater than or equal to the length of the second radiation branch 102, the first resonant frequency is less than or equal to the third resonant frequency, and greater than or equal to the second resonant frequency.

[0072] In the embodiment of the present disclosure, when λ2≤λ1-λ3≤λ1, Fre2≤Fre1≤Fre3. That is, by adjusting the length of the second radiation branch, the first resonant frequency and the third resonant frequency can be made greater than the second resonant frequency. That is, in the embodiment of the present disclosure, by adjusting the length of the second radiation branch, the magnitude relationship between the second resonant frequency and the first resonant frequency and the second resonant frequency can be changed. In this way, by flexibly adjusting the length of the second radiation branch, the antenna module can be adapted to different antenna bandwidth requirements.

[0073] In some embodiments, Figure 1 As shown, when the length of the first radiation branch 101 is less than or equal to the length of the second radiation branch 102, and greater than or equal to the distance from the feeding point 103 to the break F, the second resonant frequency is less than or equal to the first resonant frequency, and greater than or equal to the third resonant frequency.

[0074] In the embodiment of the present disclosure, when λ1-λ3≤λ1≤λ2, Fre3≤Fre2≤Fre1. That is, by adjusting the length of the second radiation branch, the second resonant frequency can be located between the first resonant frequency and the third resonant frequency. That is, in the embodiment of the present disclosure, by adjusting the length of the second radiation branch, the magnitude relationship between the second resonant frequency and the first resonant frequency and the second resonant frequency can be changed. In this way, by flexibly adjusting the length of the second radiation branch, the antenna module can be adapted to different antenna bandwidth requirements.

[0075] In some embodiments, Figure 4 As shown, the antenna module also includes:

[0076] RF front end assembly 104;

[0077] The feeding circuit 105 is electrically connected to the connection line between the feeding point 103 and the RF front-end component 104 and is configured to adjust the first resonant frequency, the second resonant frequency or the third resonant frequency.

[0078] In the embodiment of the present disclosure, the RF front-end component is configured to generate a first electrical signal and receive a second electrical signal.

[0079] Here, the RF front-end component includes: a first amplifier, an antenna switch, a filter, a duplexer, and a second amplifier. Among them, the first amplifier is used to amplify the first electrical signal in the signal output channel. The antenna switch is used to switch between the reception of the second electrical signal and the transmission of the first electrical signal, and between different frequency bands of the antenna. The filter is used to pass the signal of a specific frequency band and filter out the signal outside the specific frequency band. The duplexer is used to isolate the transmitted first electrical signal and the received second electrical signal, so that the antenna module can work normally when receiving and transmitting wireless signals at the same time. The second amplifier is used to amplify the second electrical signal of the signal receiving channel. In this way, the reception of the second electrical signal and the transmission of the first electrical signal can be realized through the RF front-end component, so that the antenna module can better send and receive wireless signals.

[0080] The above-mentioned feeding circuit can increase at least one of the three resonant frequencies of the first resonant frequency, the second resonant frequency and the third resonant frequency, and can also decrease at least one of the three resonant frequencies of the first resonant frequency, the second resonant frequency and the third resonant frequency, and the embodiments of the present disclosure are not limited to this.

[0081] In the embodiment of the present disclosure, by adjusting the first resonant frequency, the second resonant frequency or the third resonant frequency through the feeding circuit, the three resonant frequencies can be adjusted to appropriate positions, thereby further expanding the working bandwidth of the antenna.

[0082] In some embodiments, Figure 4 As shown, the feeding circuit 105 includes:

[0083] The first impedance component 105a is electrically connected to the connection line between the feeding point 103 and the RF front-end component 104, and is configured to adjust the first resonant frequency, the second resonant frequency or the third resonant frequency in a direction of reducing the lowest resonant frequency of the antenna module.

[0084] In the embodiment of the present disclosure, the first impedance component may include at least one resistor, at least one inductor and at least one capacitor. Here, in the connection line between the feed point and the RF front-end component, the first resonant frequency, the second resonant frequency or the third resonant frequency may be lowered in the direction of reducing the lowest resonant frequency of the antenna module by introducing at least one inductor connected in parallel and at least one capacitor connected in series.

[0085] Exemplarily, when the third resonant frequency is less than or equal to the first resonant frequency and greater than or equal to the second resonant frequency, the second resonant frequency and the third resonant frequency may be adjusted lower, thereby reducing the lowest resonant frequency of the antenna module;

[0086] When the first resonant frequency is less than or equal to the third resonant frequency and greater than or equal to the second resonant frequency, the first resonant frequency and the second resonant frequency can be adjusted to be lowered, thereby reducing the lowest resonant frequency of the antenna module;

[0087] When the second resonant frequency is less than or equal to the first resonant frequency and greater than or equal to the third resonant frequency, the third resonant frequency and the second resonant frequency may be adjusted lower, thereby reducing the lowest resonant frequency of the antenna module.

[0088] In some embodiments, Figure 4 As shown, the feeding circuit 105 further includes:

[0089] The second impedance component 105b is electrically connected to the connection line between the feeding point 103 and the RF front-end component 104, and is configured to adjust the first resonant frequency, the second resonant frequency or the third resonant frequency in the direction of increasing the maximum resonant frequency of the antenna module.

[0090] In the embodiment of the present disclosure, the first impedance component and the second impedance component may be connected in series between the feed point and the RF front-end component. The second impedance component may include at least one resistor, at least one inductor and at least one capacitor. Here, in the connection line between the feed point and the RF front-end component, the first resonant frequency, the second resonant frequency or the third resonant frequency may be increased in the direction of increasing the highest resonant frequency of the antenna module by introducing at least one inductor connected in series and at least one capacitor connected in parallel.

[0091] Exemplarily, when the third resonant frequency is less than or equal to the first resonant frequency and greater than or equal to the second resonant frequency, the first resonant frequency and the third resonant frequency may be adjusted higher, thereby increasing the maximum resonant frequency of the antenna module;

[0092] When the first resonant frequency is less than or equal to the third resonant frequency and greater than or equal to the second resonant frequency, the first resonant frequency and the third resonant frequency can be adjusted higher, thereby increasing the maximum resonant frequency of the antenna module;

[0093] When the second resonant frequency is less than or equal to the first resonant frequency and greater than or equal to the third resonant frequency, the first resonant frequency and the second resonant frequency can be adjusted higher, thereby increasing the maximum resonant frequency of the antenna module.

[0094] Exemplarily, the embodiment of the present disclosure regards the scheme in which the length of the second radiating branch is between the length of the first radiating branch and the distance from the feeding point to the break as Scheme 1, and regards the scheme in which the distance from the feeding point to the break is between the length of the first radiating branch and the length of the second radiating branch as Scheme 2. Figure 3 It is a schematic diagram of radiation efficiency simulation of Scheme 1 and Scheme 2 shown as an exemplary embodiment. Figure 3 In the figure, the horizontal axis is the frequency in GHz, and the vertical axis is the radiation efficiency in dB. Figure 2 and Figure 3 It can be seen that the radiation efficiency of Scheme 1 and Scheme 2 is better than the radiation efficiency of the existing antenna switch.

[0095] The present disclosure also provides an electronic device, Figure 5 is a schematic diagram of a structure of an electronic device according to an exemplary embodiment Figure 1 .like Figure 5 As shown, the electronic equipment includes:

[0096] The antenna module 100 in one or more of the above embodiments;

[0097] The conductive frame 200 is multiplexed into the first radiation branch 101 and the second radiation branch 102 in the antenna module 100 .

[0098] In the embodiments of the present disclosure, the electronic device may include a mobile phone, a notebook, a tablet computer or a wearable device, which is not limited in the embodiments of the present disclosure.

[0099] It should be noted that the embodiments of the present disclosure can reuse the conductive frame as a first radiation branch and a second radiation branch, thereby reducing the space occupied by the antenna module in the electronic device and improving the space utilization rate of the electronic device.

[0100] Furthermore, the disclosed embodiment includes an antenna module, in which the first radiating branch and the second radiating branch can receive and transmit different resonant frequencies. In this way, the antenna module of the disclosed embodiment can receive and transmit different resonant frequencies by adding the second radiating branch on the basis of the first radiating branch and coupling with the second radiating branch, and does not need to switch the antenna switch to receive and transmit different resonant frequencies, which can expand the antenna bandwidth of the antenna module and improve the frequency band range of the antenna module receiving and transmitting wireless signals. In addition, the disclosed embodiment receives and transmits wireless signals through the first radiating branch and the second radiating branch, which can increase the radiation area of ​​the antenna module, thereby improving the efficiency of the antenna module in receiving and transmitting wireless signals.

[0101] In some embodiments, the conductive frame includes a first frame and a second frame intersecting each other; the length of the second frame is greater than the length of the first frame;

[0102] Two frame parts spaced apart in the second frame are reused as the first radiation branch and the second radiation branch, respectively.

[0103] In the embodiment of the present disclosure, by multiplexing a second frame whose length is relatively long to the first frame as a first radiating branch and a second radiating branch, the first radiating branch and the second radiating branch can be better coupled to transmit and receive different resonant frequencies, thereby expanding the antenna bandwidth of the antenna module.
