[0003] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art

[0004] As people's quality of life continues to improve and their lives become more fulfilling, their expectations for communication quality in various scenarios are becoming increasingly stringent. For example, phone calls and internet access in weak signal conditions (e.g., elevators, underground parking garages, outdoors, high-speed trains and subways, and even in bedroom and bathroom corners) are becoming increasingly demanding. Consequently, the performance requirements for various communication functions on mobile terminals are becoming increasingly stringent, as are the requirements for antenna functionality to be adaptable to these scenarios.

[0005] In related technologies, antenna scene adaptation design requires adding new components, or adding electronic devices, as well as increasing the development of software algorithms, which will increase the production cost of electronic equipment.

[0006] Summary of the Invention

[0007] The purpose of the embodiment of the present application is to provide an electronic device that utilizes a battery metal compartment and connectors to form an antenna energy structure, transfers the radiation energy on the antenna radiator, and can adapt to more communication scenarios.

[0008] In a first aspect, an embodiment of the present application provides an electronic device, comprising: a first radiator, a battery metal compartment, and a connector;

[0009] The first radiator comprises a first end and a second end, and a feeding point of the first radiator is located between the first end and the second end;

[0010] The battery metal compartment includes a first side wall and a back plate, wherein the first side wall is arranged on the periphery of the back plate, and the back plate is grounded;

[0011] The first radiator is located outside the battery metal compartment, and a first gap is formed between the first radiator and the first side wall;

[0012] The connecting member is located in the first gap and connects the first portion of the first side wall and the second portion of the first radiator; the second portion is located between the first end of the first radiator and the feeding point;

[0013] A first through hole is formed on the first side wall, extending along the length direction of the first radiator, and is arranged between the first portion and the back plate; or a distributed inductor is formed between the connecting member and the first side wall.

[0014] In an embodiment of the present application, the first side wall on the battery metal compartment is connected to the first radiator through a connector, and the back plate of the battery metal compartment is grounded. A first through hole extending along the length direction of the first radiator can be opened on the first side wall to form a distributed inductance ground structure, or a connector connected between the first side wall and the first radiator is used to form a distributed inductance with the first side wall. In this way, the distributed inductance ground structure is used to allow the excitation current on the first radiator to pass through the distributed inductance ground structure to the ground, so as to achieve the transfer of energy in the first area on the first radiator to the second area. The first area is the area between the first end and the first part, and the second area is the area between the first end and the third part. This can enable part of the energy of the antenna module to be transferred to the hand-holding area in a horizontal screen gaming scenario away from the electronic device, thereby reducing the hand-holding effect and improving the antenna performance in this scenario.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0031] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0032] In related technologies, the metal frame of an electronic device can be used to form an antenna radiator. The electronic device in the embodiment of the present application can be any electronic device with an antenna, such as a mobile phone, a tablet computer, a base station, a watch, a notebook, etc. For the sake of convenience, the embodiment of the present application takes the electronic device as an example of a mobile phone, which does not constitute a specific limitation.

[0033] Mobile phones and other electronic devices can have a variety of hand-held scenarios, such as portrait and landscape scenarios. In different hand-held scenarios, the user's hand will block part of the antenna on the electronic device, thereby affecting the antenna performance.

[0034] In related technologies, the following methods can be used to overcome the problem of reduced antenna performance of a communication device caused by human body occlusion when the user holds the communication device:

[0035] 1) Antennas operating in various standards need to adapt to various scenarios, such as Long Term Evolution (LTE), New Radio (NR), Wireless Fidelity (WIFI), and Global Positioning System (GPS). However, the scenario adaptation design proposed in this solution usually focuses on the high frequency part.

[0036] 2) Low-frequency bands often face challenges with adaptability due to the size limitations of mobile devices, making them more adaptable to different scenarios. Currently, the common approach is to add switches combined with software algorithms to switch between different antennas, or to add additional components, a common approach used in mid- and high-frequency bands.

[0037] However, the above method has at least the following defects: First, the antenna scene adaptation design in the related technology is more focused on high frequencies; second, the antenna scene adaptation design in the related technology requires new components, or additional electronic devices (such as antenna switches), as well as increased software algorithm development, which often require a large increase in costs.

[0038] In an embodiment of the present application, the first side wall on the battery metal compartment is connected to the first radiator through a connector, and the back plate of the battery metal compartment is grounded. A first through hole extending along the length direction of the first radiator can be opened on the first side wall to form a distributed inductance ground structure, or a connector connected between the first side wall and the first radiator is used to form a distributed inductance with the first side wall. In this way, the distributed inductance ground structure is used to allow the excitation current on the first radiator to pass through the distributed inductance ground structure to the ground, so as to realize the transfer of energy in the first area on the first radiator to the second area. The first area is the area between the first end and the first part, and the second area is the area between the first end and the third part. This can enable part of the energy of the antenna module to be transferred to the hand-holding area in a horizontal screen gaming scenario away from the electronic device, thereby reducing the hand-holding effect and improving the antenna performance in this scenario.

[0039] In addition, compared with related technologies, the embodiments of the present application do not require new electronic devices or matching of software algorithms, thereby improving the scene adaptability of the antenna while reducing the structural complexity and production cost of the antenna module.

[0040] It is worth mentioning that the antenna module in the electronic device provided in the embodiment of the present application can be a low-frequency working module or a medium-high frequency antenna module. For the sake of convenience, the embodiments of the present application are usually illustrated by taking the antenna module as a low-frequency working module, which does not constitute a specific limitation here.

[0041] The electronic device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0042] Example 1

[0043] Referring to FIG1 , an electronic device provided in an embodiment of the present application includes: a first radiator 10 , a battery metal compartment 20 , and a connector 30 ;

[0044] The first radiator 10 includes a first end and a second end, and a feeding point A of the first radiator 10 is located between the first end and the second end;

[0045] The battery metal compartment 20 includes a first side wall D1 and a back plate G1. The first side wall D1 is disposed around the periphery of the back plate G1, and the back plate G1 is grounded.

[0046] The first radiator 10 is located outside the battery metal compartment 20 , and a first gap 31 is formed between the first radiator 10 and the first side wall D1 ;

[0047] The connecting member 30 is located in the first gap 31 and connects the first portion B1 of the first side wall D1 and the second portion B2 of the first radiator 10 . The second portion B2 is located between the first end of the first radiator 10 and the feeding point A.

[0048] A first through hole S1 is defined on the first side wall D1 and extends along the length of the first radiator 10 . The first through hole S1 is located between the first portion B1 and the back plate G1 . Alternatively, a distributed inductor is formed between the connector 30 and the first side wall D1 .

[0049] During operation, the feed F1 provides an excitation current to the first radiator 10 through the feed point A, wherein at least part of the excitation current is distributed inductively to the ground through the connector 30, so that the connector 30 is used to transfer at least part of the excitation current in the first area on the first radiator 10 to the second area on the first radiator 10, the first area being the area between the first end and the feed point A, and the second area being the area between the first end and the second part B2.

[0050] In some embodiments, the first end of the first radiator 10 may be the end of the first radiator 10 facing the second slit SL1 as shown in FIG. 1 , and the second end of the first radiator 10 may be the end of the first radiator 10 facing the third slit SL2 as shown in FIG. 1 .

[0051] Optionally, the first end is located at a first long side of the electronic device, and the second end is located at a first short side of the electronic device, and the first long side is adjacent to the first short side.

[0052] Feed point A can be located in the corner area between the first long side and the first short side. The corner area is located within the horizontal screen hand-holding area of ​​the electronic device, that is, the radiation energy in the first area will be blocked by the user's hand. If the energy is radiated through the first area, it will affect the antenna performance.

[0053] Optionally, the first radiator 10 is divided into a first sub-radiator and a second sub-radiator, with the feed point A serving as the boundary. The first sub-radiator and the second sub-radiator are respectively disposed on adjacent sides of the metal frame. For example, the first sub-radiator is the radiator between the feed point A and the second slit SL1, and the second sub-radiator is the radiator between the feed point A and the third slit SL2. In this case, it is assumed that the first sub-radiator is located on the long side of the metal frame, and the second sub-radiator is located on the short side of the metal frame.

[0054] At this time, the area between the feeding point A and the second part B2 can be located within the horizontal screen holding area of ​​the electronic device. The horizontal screen holding area represents the area held or blocked by the user's fingers when the electronic device is in a horizontal screen application scenario.

[0055] Optionally, the second portion B2 is located in a target area on the first long side, and the target area is located outside a horizontal screen grip area of ​​the electronic device.

[0056] In this embodiment, the second portion B2 is set outside the horizontal screen holding area of ​​the electronic device. When the radiation energy in the first area is transferred to the second area, the second area is also located outside the horizontal screen holding area of ​​the electronic device.

[0057] In some embodiments, in order to set the second part B2 within the target area, the distance between the second part B2 and the first short side can be greater than or equal to 1 / 6 or 1 / 5 of the length of the first long side.

[0058] Optionally, the length of the first sub-radiator may be greater than or equal to half of the long side of the metal frame, and the length of the second sub-radiator may be greater than or equal to half of the short side of the metal frame.

[0059] When the length of the first sub-radiator is greater than or equal to half of the long side of the metal frame, the area of ​​the first sub-radiator close to the first end is obviously located outside the horizontal screen grip area of ​​the electronic device.

[0060] Optionally, an end portion of the second sub-radiator close to the third slit SL2 may be grounded via a tuning module SW0 , and the tuning module SW0 may achieve frequency tuning of the antenna.

[0061] Of course, for antenna radiators of different types or structures, it is not necessary to have slits at both ends. For example, the ends of the antenna radiator can be connected to other metal structures and grounded through a ground feed structure. The radiator can also be placed in other areas of the metal frame, or even in locations other than the metal frame. For ease of explanation, the embodiment of the present application uses an example in which the first radiator 10 is placed on the metal frame, and the second slit SL1 and the third slit SL2 are respectively provided at both ends of the first radiator 10. The structure of the first radiator 10 is not specifically limited herein.

[0062] In this embodiment, the first region on the first radiator 10 may be the area between the second slit SL1 and the feed point A, and the second region on the first radiator 10 may be the area between the second slit SL1 and the second portion B2. In other words, the energy transfer path may be from the feed point A to the second portion B2, with the distributed inductor grounded via the connector 30.

[0063] In some embodiments, the position of the second portion B2 can be adjusted according to the user's hand-holding area in different application scenarios, that is, the distance between the feeding point A and the second portion B2 is adjustable.

[0064] For example: as shown in Figure 1, in a horizontal screen scenario, the user's hand usually blocks the lower right corner of the metal frame shown in Figure 1, and the area between the feeding point A and the second part B2 is located in the blocked area in the horizontal screen scenario, so the position of the second part B2 is adjusted to move the energy between the feeding point A and the second part B2 outside the blocked area.

[0065] In some embodiments, a battery metal compartment 20 is provided on an electronic device such as a mobile phone, and the battery metal compartment 20 is used to accommodate a battery. The first radiator 10 can be disposed outside the battery metal compartment 20 and spaced apart from the first side wall D1 of the battery metal compartment 20. That is, the first side wall D1 can be a side wall on the battery metal compartment 20 that is parallel to the second region on the first radiator 10 (i.e., the region between the second slit SL1 and the second portion B2) and is closest to the first radiator 10. In addition, as shown in FIG2 , the back plate of the battery metal compartment 20 can be grounded, so that the back plate of the battery metal compartment 20 can be regarded as the main ground. That is, the bottom of the first side wall D1 is connected to the main ground. In this way, the second portion B2 on the first radiator 10 can be connected to the main ground through the connector 30 and the first side wall D1.

[0066] For example: as shown in Figure 1, the first radiator 10 is set on a metal frame, the metal frame surrounds the outside of the battery metal compartment 20, and there is a gap between the metal frame and the circumference of the battery metal compartment 20. At this time, a connector 30 can be set in the first gap 31 between the side wall of the battery metal compartment 20 close to the first radiator 10 and the first radiator 10, so as to realize the excitation current of the second part B2 of the first radiator 10 to be grounded through the connector 30 and the battery metal compartment, thereby realizing the transfer of energy between the second part B2 and the feeding point A to between the second part B2 and the second slit SL1.

[0067] It should be noted that, in implementation, the antenna module in the electronic device shown in FIG1 has the following three operating modes under the operating frequency band:

[0068] Bottom monopole mode M11, i.e., the monopole mode excited on the second sub-radiator;

[0069] The side inverted-F antenna (IFA) mode M12, i.e., the IFA mode excited on the first sub-radiator;

[0070] The half-wavelength mode M21 is formed on the entire first radiator 10 .

[0071] The mode for realizing energy transfer may be the side IFA mode M12, that is, in the M12 mode, the energy in the first region is transferred to the second region.

[0072] It is worth noting that in the related art, if the connector 30 is not provided to connect to the battery metal compartment 20, then in the side IFA mode, the energy on the first radiator 10 is distributed between the feed point A and the second slit SL1. However, in the embodiment of the present application, in the side IFA mode, the energy on the first radiator 10 is distributed between the second portion B2 and the second slit SL1, thereby achieving partial energy transfer, which is conducive to flexible adjustment of the distribution range of the antenna radiation energy on the first radiator 10. In this way, when applied to a specific scenario, the radiation energy on the first radiator 10 can be transferred to an area not blocked by the user's hand according to the user's hand-holding area in the scenario, thereby improving the antenna performance in the scenario.

[0073] In some embodiments, if the second portion B2 is directly grounded through the connector 3, it may be difficult to excite the IFA mode M12. A distributed inductor grounding structure can be set at the strong current point of the IFA mode M12. At this time, the distributed inductor grounding also allows the energy in the wide frequency band to pass through the grounding point and then excite the IFA mode M12 in the second region between the second slit SL1 and the second portion B2. At the same time, due to the introduction of this distributed inductance, there is better impedance matching in the wide frequency band. Therefore, within the operating frequency band, a traveling wave transmission characteristic will be formed between the feeding point A and the second portion B2, thereby more effectively realizing the transfer of the side IFA mode M12 from the first region to the second region.

[0074] In an optional embodiment, the length direction of the first through hole S1 is parallel to the first radiator 10 , which can be understood as: the length direction of the first through hole S1 is parallel to the portion of the first radiator 10 located in the second region.

[0075] The first through hole S1 is arranged between the first part B1 and the back plate G1. It can be understood that the first part B1 and the back plate G1 are distributed on both sides of the first through hole S1. For example, as shown in Figure 2, a first through hole S1 extending laterally is opened on the first side D1, wherein the first part B1 is located on the upper side of the first through hole S1, and the back plate G1 is located on the lower side of the first through hole S1.

[0076] In this embodiment, a distributed inductance structure can be formed by using the first through hole S1. For example, as shown in Figure 2, based on the first through hole S1, the current at the second part B2 on the first radiator 10 can be discharged to the ground through the distributed inductance path L1 and the distributed inductance path L2, that is, the antenna energy flows back to the backplane G1 (that is, the main ground) through the two paths L1 and L2 through the connector 30.

[0077] Optionally, the length of the first through hole S1 is less than or equal to 1 / 2 wavelength of the first working frequency band of the antenna module corresponding to the first radiator 10 .

[0078] In the case where the antenna module is a low-frequency antenna, the first operating frequency band of the antenna module may be a low-frequency band. In this case, the length of the first through hole S1 may be between 30 mm and 60 mm.

[0079] In this embodiment, by controlling the length of the first through hole S1 to be within 1 / 2 wavelength of the first operating frequency band of the antenna module, the resonance interference generated by the first through hole S1 can be reduced.

[0080] It is worth mentioning that in some embodiments, the length of the first through hole S1 can be adjusted to excite a high-frequency slot mode (such as N41 / N78 / N79, etc.) in the slot structure of the first through hole S1, thereby increasing the operating frequency band of the antenna module.

[0081] Optionally, the length of the area between the feeding point A and the second part B2 in the first radiator is less than or equal to 1 / 2 wavelength of the first working frequency band, and the first working frequency band is the working frequency band of the antenna module corresponding to the first radiator 10.

[0082] When the antenna module is a low-frequency antenna, the operating frequency band of the antenna module may be a low-frequency band, that is, the length from the feed point A to the second portion B2 is less than or equal to 1 / 2 wavelength of the operating frequency band of the antenna module.

[0083] It is worth noting that when the length from the feeding point A to the second part B2 exceeds 1 / 2 wavelength of the first operating frequency band of the antenna module, additional influencing modes may be introduced, which will interfere with the existing modes of the antenna module, such as the bottom monopole mode M11, the side IFA mode M12, and the half-wavelength mode M21 on the entire first radiator 10.

[0084] The first operating frequency band may be an operating frequency band corresponding to the bottom monopole mode M11 on the first radiator 10 , the side IFA mode M12 , and the half-wavelength mode M21 on the entire first radiator 10 , such as a low-frequency operating frequency band.

[0085] In another optional embodiment, the connector 30 can also be used to form a distributed inductor structure, or an inductor can be connected in series with the connector 30. For example, as shown in FIG11 , the connector 30 includes a third connecting portion PL1 that is parallel to and spaced from the first sidewall D1. In this way, a distributed inductor can be formed using PL1 and the first sidewall D1. Alternatively, as shown in FIG14 , a second switching module Q1 can be connected in series with the connector 30 to adjust at least one of the ground capacitance, resistance, and inductance of the second portion B2.

[0086] It is worth noting that, compared with the above-mentioned method of using the connector 30 to form a distributed inductor structure or connecting the inductor in series on the connector 30, the method of using the first through hole S1 on the first side D1 to realize the grounding of the distributed inductor does not require increasing the gap between the battery metal compartment 20 and the metal frame to set a connector 30 with a more complex structure, thereby eliminating the need to occupy the space of the battery metal compartment 20 and not reducing the battery capacity.

[0087] Of course, the first through hole S1 may be opened on the first side D1 to realize the grounding of the distributed inductor, and the structure of the connecting member 30 as shown in FIG. 11 may also be provided, which is not specifically limited here.

[0088] Corresponding to the electronic device shown in Figures 1 and 2, the first radiator 10 of the antenna module in the electronic device is set on the metal frame of the mobile phone. At this time, the antenna module in the electronic device of the embodiment of the present application can transfer part of the energy on the antenna radiator to improve the antenna performance of the electronic device in various scenarios.

[0089] Specifically, assuming that the antenna module in the electronic device shown in Figures 1 and 2 and the antenna module in the related technology both operate in the N28 (approximately 0.705GHz-0.805GHz) frequency band, as shown in Figure 4, the antenna module in the electronic device shown in Figures 1 and 2 has a significantly improved radiation efficiency in various scenarios, such as the left-hand holding mobile phone scenario and the right-hand holding mobile phone scenario, compared with the antenna module that does not perform energy transfer.

[0090] In addition, as shown in FIG5 , by comparing the low-frequency total efficiency in free space and left and right hand modes, it can be concluded that in terms of total efficiency, the antenna modules shown in FIG1 and FIG2 are also significantly superior to the antenna modules in related technologies.

[0091] Example 2

[0092] As shown in FIG6 , based on the first embodiment described above, the embodiment of the present application further comprises a first break S2 on the first side wall D1 , the first break S2 is connected to the first gap 31 and the first through hole S1 , and the first portion B1 is located on one side of the first break S2 .

[0093] In the embodiment shown in Figure 6, the first portion B1 is located on the left side of the first slit S2, that is, on the side wall of the first slit S2 near the second slit SL1. In another embodiment, the first portion B1 can be located on the right side of the first slit S2, which is not specifically limited here. For ease of explanation, the embodiment of this application uses the example of the first portion B1 being located on the left side of the first slit S2 for illustration, which is not a specific limitation here.

[0094] In this embodiment, the first gap 31 and the first through hole S1 are connected through the first break S2. At this time, the ground path of the antenna energy at the second part B2 is: connecting part 30-->first part B1-->L1-->G1, and the area between the side wall of the first through hole S1 located on the right side of the first break S2 and the back plate G1 can form a resonant path L2.

[0095] That is to say, in this embodiment, the ground return path L1 and the connector 30 are used to form an energy transmission segment, and the first through hole S1 can form a high-frequency working resonance (such as N41 / N78 / N79). At the same time, the area between the side wall of the first through hole S1 located on the right side of the first break S2 and the back plate G1 can also form a high-frequency working resonance (such as N41 / N78 / N79), thereby greatly broadening the working frequency band of the antenna module.

[0096] Optionally, the distance between the first portion B1 and the first short side SC1 of the first through hole S1 is less than or equal to 1 / 2 wavelength of the first operating frequency band, and the first portion B1 and the first short side SC1 are located on the same side of the first break.

[0097] Optionally, in actual engineering, the distance between the first portion B1 and the first short side SC1 of the first through hole S1 may be controlled to be between 30-60 mm.

[0098] In this embodiment, by limiting the distance between the first portion B1 and the first short side SC1 of the first through hole S1 to be less than or equal to 1 / 2 wavelength of the first working frequency band, the resonance interference caused by the slot between the first portion B1 and the short side SC1 of the first through hole S1 can be reduced.

[0099] As shown in Figure 3, the working frequency bands of the antenna module in the electronic device provided in the first embodiment of the present application may include three, namely: AL01, AL02 and AL03, among which AL01 and AL02 are two low-frequency working resonances (formed by the M11 mode, M12 mode and M21 mode on the entire first radiator 10 between the second slit SL1 and the third slit SL2), and AL03 is a resonance working in the medium and high frequency parts (corresponding to the half-wavelength slot mode formed by the first through hole S1, which can be N41 or other frequency bands).

[0100] As shown in Figure 7, the working frequency bands of the antenna module in the electronic device provided in the second embodiment of the present application may include 4, namely: AL1, AL2, AL3 and AL4, among which AL1 and AL2 are two low-frequency working resonances (formed by the M11 mode, M12 mode and M21 mode on the entire first radiator 10 between the second slit SL1 and the third slit SL2), AL3 is a resonance working in the medium and high frequency parts (corresponding to the half-wavelength slot mode formed by the first through hole S1, which can be N41 or other frequency bands), and AL4 is a resonance working in the higher frequency part (corresponding to the IFA 1 / 4 wavelength mode formed in the area between the side wall of the first through hole S1 located on the right side of the first break S2 and the back plate G1, which can be N78 or N79 or other frequency bands).

[0101] 3 and 7 , it can be seen that the second embodiment can increase the working frequency band of the antenna module in the medium and high frequency range by adding the first break S2 .

[0102] Example 3

[0103] Referring to Figure 8 , compared to the second embodiment described above, the present embodiment of the present application adds a first switching module 40 between the two ends of the first break S2. The first switching module 40 is connected between the two ends of the first break S2, and the first parameter of the first switching module 40 is adjustable, including at least one of a capacitance value, a resistance value, and an inductance value.

[0104] Optionally, in some embodiments, the first switching module 40 may include at least one of a switching switch, a capacitor, a resistor, an inductor, and other devices, based on which at least one of the capacitance value, the resistance value, and the inductance value between the two opposite side walls of the first break S2 can be adjusted.

[0105] For example, as shown in FIG9 , the first switching module 40 may include a switching switch SW1 , one end of which is connected to a side wall of the first break S2 , and the other end of the switching switch SW1 is connected to the other side wall of the first break S2 through different resistors, capacitors, and inductors such as a first inductor LG1 , a second inductor LG2 , and a first capacitor CG1 . In this way, at least one of the capacitance value, resistance value, and inductance value between the two opposite side walls of the first break S2 can be switched by switching the switch SW1 .

[0106] Optionally, the first switching module 40 can be connected between the opposite side walls of the first break S2 by spot welding on a flexible printed circuit (FPC), or can be connected between the opposite side walls of the first break S2 by a spring clip on a hard board such as a printed circuit board (PCB).

[0107] In this embodiment, the first switching module 40 can be used to adjust at least one of the capacitance value, resistance value and inductance value between the two opposite side walls of the first break S2, so as to achieve frequency tuning of the moved M12 mode, so that the antenna module can operate in more frequency bands, so that more low-frequency bands can improve the antenna performance in the hand-held scenario.

[0108] For example: as shown in Figure 10, by adjusting at least one of the capacitance value, resistance value and inductance value between the opposite side walls of the first break S2 through the first switching module 40, the AL1 frequency band and the AL2 frequency band shown in Figure 7 can be switched from the N28 frequency band to the N8 frequency band, and / or, the AL3 frequency band shown in Figure 7 can be switched from the N41 frequency band to the N3 frequency band, and / or, the AL4 frequency band in Figure 7 can be switched from the N78 frequency band to the N79 frequency band or the WIFI 5G frequency band.

[0109] Example 4

[0110] Compared with the first embodiment described above, the embodiment of the present application improves the connecting member 30 .

[0111] As shown in FIG11 or FIG12 , the connecting member 30 includes: a first connecting portion P2 , a second connecting portion P1 and a third connecting portion PL1 ;

[0112] The first connection portion P2 connects the first part B1 , the second connection portion P1 connects the second part B2 , and the third connection portion PL1 is connected between the first connection portion P2 and the second connection portion P1 .

[0113] In this embodiment, the first connection portion P2 , the second connection portion P1 , and the third connection portion PL1 may be located on the same straight line or on different straight lines.

[0114] For example, as shown in Figure 11, the third connection portion PL1 is parallel to and spaced from the first side wall D1, with the first connection portion P2 and the second connection portion P1 located at either end of the third connection portion PL1. In this case, the gap between the third connection portion PL1 and the first side wall D1 forms a distributed inductor ground plane structure, eliminating the need for a first through hole S1 on the first side wall D1. This improves the structural strength of the battery metal compartment 20 compared to the embodiment in which the first through hole S1 is provided on the first side wall D1.

[0115] For another example, as shown in FIG12 , the first connection portion P2 , the second connection portion P1 and the third connection portion PL1 may be located on the same straight line. In this case, a first through hole S1 may be opened on the first side wall D1 to form a distributed inductor ground structure.

[0116] In one embodiment, as shown in Figure 11 or Figure 12, the first connection part P2, the second connection part P1 and the third connection part PL1 can together form a metal ultrasonic FPC. At this time, ultrasonic welding FPC can be used to achieve the connection between the first connection part P2 and the first part B1, and the connection between the second connection part P1 and the second part B2.

[0117] In another embodiment, as shown in Figure 13, a small plate 32 can be set in the first gap 31, such as a circuit board in the form of PCB, FPC, liquid crystal polymer (LCP), modified polyimide (MPI), etc., and a first spring piece TP1 and a second spring piece TP2 can be set at both ends of the small plate 32, respectively, wherein the small plate 32 can be horizontally or vertically embedded in the plastic in the first gap 31, so that one end of the first spring piece TP1 is fixedly connected to the small plate 32, and the other end is used to be pressed on the first part B1; one end of the second spring piece TP2 is fixedly connected to the small plate 32, and the other end is used to be pressed on the second part B2, and the first spring piece TP1 and the second spring piece TP2 can be connected on the small plate 32 by a metal wire.

[0118] In other words, the first spring piece TP1 serves as the first connection portion, the second spring piece TP2 serves as the second connection portion, and the metal wire connecting the first spring piece TP1 and the second spring piece TP2 serves as the third connection portion.

[0119] In this embodiment, the connection method of using spring plates pressed at corresponding positions does not require ultrasonic welding compared to the ultrasonic welding FPC connection method shown in Figures 11 or 12, which reduces the assembly complexity and assembly cost of the antenna module. At the same time, compared to the above-mentioned welding structure, it can also improve the connection reliability. For example, the welding may not crack when impacted.

[0122] Optionally, the third connecting portion includes:

[0123] The second switching module Q1 is connected in series between the first connecting portion and the second connecting portion. The second parameter of the second switching module Q1 is adjustable, and the second parameter includes at least one of a capacitance value, a resistance value, and an inductance value.

[0124] Optionally, the structure of the second switching module Q1 is similar to that of the first switching module 40. For example, the second switching module Q1 may include at least one of a switching switch, a capacitor, a resistor, an inductor and other devices. Based on the second switching module Q1, at least one of the capacitance value, resistance value and inductance value between the first spring piece TP1 and the second spring piece TP2 can be adjusted.

[0125] The second switching module Q1 can be connected in series between the first spring piece TP1 and the second spring piece TP2 via metal wires on the small board 32 .

[0126] For example, as shown in FIG15 , the second switching module Q1 may include a switching switch SW2, one end of which is connected to the first spring piece TP1, and the other end of which is connected to the second spring piece TP2 via different resistors, capacitors, and inductors, such as a third inductor L01, a fourth inductor L02, and a second capacitor C01. In this way, at least one of the capacitance value, resistance value, and inductance value between the first spring piece TP1 and the second spring piece TP2 can be switched by switching the switch SW2.

[0127] The fifth embodiment has the same beneficial effects as the spring-type connection structure shown in FIG13 . At the same time, the second switching module Q1 can be used to adjust at least one of the capacitance value, resistance value, and inductance value between the first spring type TP1 and the second spring type TP2 to achieve tuning functions for more operating frequency bands, for example, obtaining the effect of increasing the operating frequency band of the antenna module as shown in FIG10 .
