TECHNICAL FIELD

The disclosure relates to the field of mobile communication technologies, and more particularly to an antenna device and an electronic device.

BACKGROUND

At present, with the popularization of full screens and curved screens, there is less and less clearance left for antennas, and due to the increase of frequency bands such as fifth-generation mobile communication technology (5G), the number of antennas is more than long term evolution of fourth-generation mobile communication technology (4G LTE), resulting in difficult antenna layout and reduced efficiency. At present, metal frame antennas are usually used to solve problems of more antenna requirements and less clearance. However, in the related art, the number of antennas that can be made by the frame is limited, and thus more other antennas need to be added except the metal frame antennas in a device, in which more antennas added in the device would affect the antenna performance and increase the cost.

SUMMARY

The present disclosure aims to provide an antenna device and an electronic device to solve the above problems.

In order to solve the above technical problems, an electronic device is provided. The electronic device includes a metal frame disposed with multiple gaps. The multiple gaps divide the metal frame into multiple frame segments being independent from one another. The multiple frame segments are configured as antenna bodies supporting frequency bands of communication standards. At least three frame segments of the multiple frame segments support at least one fifth-generation mobile communication technology (5G) frequency band, at least one frame segment of the at least three frame segments supporting the at least one 5G frequency band further supports an middle high band (MHB) frequency band of long term evolution (LTE), and at least one frame segment of the multiple frame segments except the at least three frame segments supporting the at least one 5G frequency band supports the MHB frequency band of LTE. The at least one frame segment, supporting the MHB frequency band of LTE, of the multiple frame segments except the at least three frame segments supporting the at least one 5G frequency band is configured to realize a 5G non-standalone (NSA) communication standard together with the at least three frame segments supporting the at least one 5G frequency band.

DETAILED DESCRIPTION OF EMBODIMENTS

FIG.1illustrates a schematic plan view of a part of an internal structure of an electronic device according to an embodiment of the present disclosure. As shown inFIG.1, an electronic device100includes a metal frame10disposed with multiple gaps11. The multiple gaps11divide the metal frame10into multiple frame segments12being independent from one another. The multiple frame segments12are used as antenna bodies supporting frequency bands of communication standards. At least three frame segments of the multiple frame segments support a fifth-generation mobile communication technology (5G) frequency band, at least one frame segment of the at least three frame segments supporting the 5G frequency band further supports a middle high band (MHB) frequency band of long term evolution (LTE), and at least one frame segment of the multiple frame segments except the at least three frame segments supporting the 5G frequency band supports the MHB frequency band of LTE. The at least one frame segment, supporting the MHB frequency band of LTE, of the multiple frame segments except the at least three frame segments supporting the 5G frequency band is used to realize a 5G non-standalone (NSA) communication standard together with the at least three frame segments supporting the 5G frequency band.

Therefore, in the present disclosure, the at least one frame segment of the at least three frame segments supporting the 5G frequency band simultaneously supports the MHB frequency band of LTE, so that the number of antenna bodies can be reduced; and the 5G NSA communication standard is realized by the at least one frame segment, supporting the MHB frequency band of LTE, of except the at least three frame segments supporting 5G frequency band together with the at least three frame segments supporting 5G frequency band. The 5G NSA communication standard is mainly realized by the metal frame, so than the antenna performance is improved, and the cost is reduced.

Specifically, the frequency bands of the communication standards supported by the multiple frame segments12include frequency bands of 5G NSA, 5G standalone (SA), wireless fidelity (WIFI), global positioning system (GPS), and 2/3/4G (the 2nd/3rd/4thgeneration mobile communication technology).

Specifically, the at least three frame segments support the 5G frequency band, which means that the at least three frame segments support frequency bands under 5G NSA and/or 5G SA. The MHB of LTE refers to a middle high band under a 4G LTE communication standard.

In some embodiments, at least one gap is defined in the metal frame10at a bottom D1of the electronic device100.

Therefore, in the present disclosure, the multiple frame segments of the metal frame10are used as the antenna bodies to support the frequency bands under the multiple communication standards including 5G NSA, 5G SA, WIFI, GPS and 2/3/4G, so as to meet communication requirements, and the at least one gap is defined at a position of the metal frame10located the bottom of the electronic device100can reduce or avoid opening a gap at a position of the metal frame10located a side close to the bottom of the electronic device100, thereby avoiding the impact of being held by users during use.

The bottom D1of the electronic device100may be an end portion located at a lower end of the electronic device100when the electronic device100is placed in a right direction. A top D2of the electronic device100is generally equipped with a camera, the bottom D1is generally equipped with a connection interface such as a USB interface, and the bottom D1of the electronic device100may be specifically an end equipped with a connection interface such as a USB interface.

Specifically, different radio frequency sources S1directly or indirectly excite the corresponding frame segments12to operate, so that each frame segment12operates in the corresponding frequency band under the corresponding communication standard. For example, a certain radio frequency source S1may only directly excite the directly connected frame segment12to make the frame segment12operate, so as to realize the transmission and reception of radio frequency signals of the corresponding frequency band under the corresponding communication standard. For another example, another radio frequency source S1may directly excite the directly connected frame segment12, and may also indirectly excite the frame segments adjacent to the directly connected frame segment12through coupling feed excitation, so that the frame segment12and the adjacent frame segments may operate together to achieve the transmission and reception of radio frequency signals of the corresponding frequency band under the corresponding communication standard.

As shown inFIG.1, in this embodiment, the number of the radio frequency sources S1is greater than or equal to the number of the multiple frame segments12, and each of the frame segments12is correspondingly connected to at least one radio frequency source S1. That is, in this embodiment, each of the frame segments12is connected to the radio frequency source S1, and at least one radio frequency source S1is connected.

As shown inFIG.1, the electronic device100further includes a main board20, and the antenna device200further includes an antenna body21disposed on the main board20. The antenna body21cooperates with a part of the frame segments12to support a frequency band under one of the communication standards.

The antenna device200of the present disclosure only needs to set one antenna body21on the main board20in addition to the antenna bodies formed by the frame segments of the metal frame10, and compared with the existing solution that multiple antenna bodies21need to disposed on the main board20, the antenna performance of the present disclosure can be effectively improved. In this situation, the antenna body21set on the main board20supports a high-frequency band. Due to the strong penetrability of the high-frequency band, the antenna body21does not affect the radiation performance even if the antenna body21is located inside the electronic device100.

Specifically, the antenna body21may be a laser direct structuring (LDS) antenna formed on an antenna bracket of the main board20through laser technology, that is, the antenna bracket is disposed on the main board20, and then the LDS antenna is formed on the antenna bracket. The LDS antenna refers to a metal antenna pattern directly plated on the antenna bracket disposed on the main board20through laser technology. In other embodiments, the antenna body21may also be a flexible printed circuit board (FPC) antenna disposed on the main board20. The FPC antenna refers to a metal antenna pattern formed on the FPC, and the FPC antenna may be fixed on the main board20by means of bonding, embedding, welding, etc.

In some embodiments, at least one of the multiple frame segments12independently supports a frequency band under a certain communication standard, and at least a part of the frame segments12at least support a frequency band under a certain communication standard together with other frame segments.

As shown inFIG.1, the antenna body21on the main board20is connected to one radio frequency source S1. The antenna body21operates under excitation of excitation signals of the radio frequency source S1, and operates with other corresponding frame segments12to achieve the transmission and reception of radio frequency signals of the corresponding frequency band under the corresponding communication standard.

As shown inFIG.1, the electronic device100is substantially square, and the metal frame10is rectangular, and the metal frame10includes two opposite short frames101and two opposite long frames102. The two opposite short frames101and two opposite long frames102enclose to form the metal frame10. A position of the metal frame10located at the bottom of the electronic device100may be the position of one of the short frames101disposed with a connection interface such as a USB interface.

The two short frames101include a first short frame101aand a second short frame101b, and the two long frames102include a first long frame102aand a second long frame102b.

That is, in this embodiment, the metal frame10is defined with six gaps11, and the metal frame is divided into six independent frame segments12. In the present disclosure, the independent frame segment12refers to that the gap11completely divides the adjacent frame segments12.

The gaps11aand11bdefined on the first short frame101aare close to the first long frame102aand the second long frame102brespectively. The two gaps11dand11edefined on the first long frame102aare disposed close to the first short frame101a, and the gap11dis closer to the first short frame101athan the gap11e. The gap11cdefined on the second short frame101bis disposed close to the first long frame102a, and the gap11fdefined on the second long frame102bis disposed close to the first short frame101a.

In this case, the gap11is not disposed with a gap at a side of the electronic device100close to the bottom of the electronic device100. When the user vertically holds the electronic device100without defined with the gap at a holding position usually located at the side of the bottom of the electronic device100of the present disclosure, the user's holding will not affect the antenna radiation. In the present disclosure, the vertical holding electronic device100refers to a manner of holding the electronic device100when the electronic device100is placed in a vertical screen display state, and correspondingly, the horizontal holding electronic device100refers to a manner of holding the electronic device100when the electronic device100is placed in a horizontal screen display state.

Each of the first frame segment12a, the second frame segment12b, the fifth frame segment12eand the sixth frame segment12fforms one antenna body. Therefore, in the present disclosure, the multiple frame segments12actually form eight antenna bodies.

Specifically, a segment of the third frame segment12cbetween the gap11fand a grounded portion (i.e., the grounded preset portion B1) forms a first antenna body ANT0, and another segment of the third frame segment12cbetween the gap11cand the grounded portion (i.e., the grounded preset portion B1) forms a second antenna body ANT1. The first frame segment12aforms a third antenna body ANT2, and a segment of the fourth frame segment12dbetween the gap11cand the grounded portion (i.e., the grounded preset portion B2) forms a fourth antenna body ANT3. The fifth frame segment12eforms a fifth antenna body ANT4, and the second frame segment12bforms a sixth antenna body ANT5. The sixth frame segment12fforms a seventh antenna body ANT6.

MHB MIMO2 means that the first antenna body ANT0supports a multiple input multiple output antenna system under the middle high band.

A frequency band supported by the second antenna body ANT1is LB PRX, that is, the second antenna body ANT1supports the low band. LB PRX means that the second antenna body ANT1defaults to a main antenna body of the low band.

Frequency bands supported by the third antenna body ANT2are MHB PRX+N78/N79 PRX, N78/N79 refers to an N78/N79 band under the 5G NSA communication standard, that is, the third antenna body ANT2supports the middle high band+the N78/N79 band.

Since the N78/N79 band is a high frequency band, the requirements for antenna space are relatively low, and the antenna body21disposed on the bracket of the main board20can also better achieve the N78/N79 antenna performance.

Therefore, in the present disclosure, the multiple frequency bands of 5G NSA, 5G SA, WIFI, GPS, and 2/3/4G are implemented by the frequency bands supported by the nine antenna bodies.

As described above, the frequency bands supported by the first antenna body ANT0are LB+MHB MIMO2+N41, and the frequency band supported by the second antenna body ANT1are LB; Therefore, the first antenna body ANT0and the second antenna body ANT1both independently support the 2/3/4G communication standard, that is, they can operate independently in the 2/3/4G communication standard, so as to achieve the transmission and reception of radio frequency signals of the 2/3/4G communication standard.

That is, an antenna architecture of the 5G NSA includes the above five antenna bodies, and the at least one of the five antenna bodies simultaneously supports the LTE and 5G bands to support dual frequency bands.

Therefore, compared with the architecture that requires six antennas under the existing 5G NSA communication standard, the present disclosure can reduce one antenna body, which is more conducive to the overall layout of the antenna, reduce the deployment of antennas on the main board20, reduce the cost, and improve the overall performance of the antenna.

Similarly, the antenna bodies supporting the 5G NSA can switch between main and diversity according to the signal strength, including: switching the antenna bodies supporting the 5G NSA with relatively strong signals to the main antenna and switching the antenna bodies supporting the 5G NSA with relatively weak signals to the diversity antenna.

FIG.6illustrates a schematic view of switching of antenna bodies supporting 2/3/4G in the electronic device100according to an embodiment of the present disclosure. In order to show the switching more clearly,FIG.6is simplified, and some components are omitted compared withFIG.1.

As described above, the frequency bands supported by the first antenna body ANT0are LB+MHB MIMO2+N41, the frequency band supported by the second antenna body ANT1is LB; the frequency bands supported by the third antenna body ANT2are MHB+N78/N79, and the frequency bands supported by the fourth antenna body ANT3are MHB+N41 MIMO2, that is, the middle high band and the N41 band.

Therefore, when the electronic device100is in the network state of the 4G communication standard, the first antenna body ANT0and the second antenna body ANT1both supporting LB (i.e., the low band) form an antenna pair, and the main and diversity can be switched according to the signal strength. The third antenna body ANT2and the fourth antenna body ANT3supporting the middle high band form an antenna pair, and the main and diversity can be switched according to the signal strength.

As shown inFIG.1andFIG.6, since the first antenna body ANT0is located on the second long frame102band the second antenna body ANT1is located on the second short frame101b, in this situation, at least one of the first antenna body ANT0and the second antenna body ANT1will not be held by the user regardless of whether the user holds the electronic device100horizontally or vertically, and the signal is good. At this time, the signal quality of the LB of 2/3/4G can be guaranteed no matter whether the user holds it horizontally or vertically through the switching of the main and diversity according to the signal strength.

As shown inFIG.1andFIG.6, since the third antenna body ANT2is located on the first short frame101aand the fourth antenna body ANT3is located on the second short frame101band a top corner of the first long frame, the third antenna body ANT2and the fourth antenna body ANT3are substantially diagonally distributed on the electronic device100. In this case, at least one of the third antenna body ANT2and the fourth antenna body ANT3will not be held by the user regardless of whether the user holds the electronic device100horizontally or vertically, and the signal is good. At this time, the signal quality of the MHB of 2/3/4G can be guaranteed no matter whether the user holds horizontally or vertically through the switching of the main and diversity according to the signal strength.

FIG.7illustrates a schematic view of switching between antenna bodies supporting the 5G NSA in the electronic device100according to an embodiment of the present disclosure. In order to illustrates the switching more clearly,FIG.7is simplified, and some components are omitted compared withFIG.1.

As described above, the frequency bands supported by the first antenna body ANT0are LB+MHB MIMO2+N41, the frequency bands supported by the third antenna body ANT2are MHB+N78/N79, and the frequency bands supported by the fifth antenna body ANT4are MHB MIMO3+N41 DRX+N78/N79 DRX.

Therefore, the fifth antenna body ANT4supports both the N41 band and the N78/N79 band. When the electronic device100is in the network state of the 5G NSA communication standard, for the N41 band, the first antenna body ANT0and the fifth antenna body ANT4form an antenna pair, and the main and diversity can be switched according to the signal strength. For the N78/N79 band, the third antenna body ANT2and the fifth antenna body ANT4form an antenna pair, and the main and diversity can also be switched according to the signal strength.

As shown inFIG.1andFIG.7, since the first antenna body ANT0is located on the second long frame102b, the third antenna body ANT2is located on the first short frame101a, and the fifth antenna body ANT4is located on the first long frame102a, in this situation, at least one of the first antenna body ANT0and the fifth antenna body ANT4will not be held by the user regardless of whether the user holds the electronic device horizontally or vertically, and the signal is good. At this time, for the N41 band, the first antenna body ANT0and the fifth antenna body ANT4can be switched between the main and diversity according to the signal strength to ensure the signal quality of the N41 band of the 5G NSA communication standard. Similarly, at least one of the third antenna body ANT2and the fifth antenna body ANT4will not be held by the user regardless of whether the user holds the electronic device horizontally or vertically, and the signal is good. At this time, for the N78/N79 band, the third antenna body ANT2and the fifth antenna body ANT4can be switched between the main and diversity according to the signal strength to ensure the signal quality of the N78/N79 band of the 5G NSA communication standard.

Specifically, the range of the N41 band is 2.5 GHz to 2.69 GHz, the range of the N78 band is 3.3 GHz to 3.8 GHz, and the range of the N79 band is 4.8 GHz to 5 GHz.

FIG.8illustrates a structural block diagram of some components of the electronic device100according to an embodiment of the disclosure. Specifically, the electronic device100includes an antenna device200, a signal detector300, and a radio frequency processing circuit400. The signal detector300is configured to detect a signal strength of each pair of antenna bodies capable of switching between main and diversity according to the signal strength. The radio frequency processing circuit400is connected to the signal detector300, and is configured to switch and control each pair of antenna bodies capable of switching between main and the diversity according to the signal strength detected by the signal detector300.

Specifically, the radio frequency processing circuit400determines, according to the signal strength detected by the signal detector300, that a difference between the signal strengths of a certain pair of antennas being capable of switching between main and diversity exceeds a preset threshold value, and when the antenna body with a lower current signal strength is the main antenna body, the radio frequency processing circuit400controls to switch the antenna body with the lower current signal strength to the diversity antenna body, and controls to switch the antenna body with a higher current signal strength to the main antenna body.

The preset threshold value may be 6 decibels (dB).

For example, for the antenna pair of the first antenna body ANT0and the second antenna body ANT1supporting the LB (i.e., the low band), when the signal strength of the first antenna body ANT0is greater than the signal strength of the second antenna body ANT1detected by the signal detector300and a difference between the two signal strengths exceeds the preset threshold value, and the first antenna body ANT0is a diversity antenna, then the radio frequency processing circuit400controls to switch the first antenna body ANT0to the main antenna and the second antenna body ANT1to the diversity antenna.

The radio frequency processing circuit400may include a controller, a switching switch and other elements to realize the switching between main and diversity.

As shown inFIGS.1-5, the electronic device100also includes a front housing30, the front housing30is configured to support a display screen and the like of the electronic device100and to provide a reference ground.

As shown inFIG.1, the preset portion B1between the two radio frequency sources S1of the third frame segment12cextends inward, that is, an extension part Y1extends towards a direction of the front housing30, and the extension part Y1is in contact with the front housing30to connect the reference ground. The preset portion B2between the two radio frequency sources S1of the fourth frame segment12dextends inwards, that is, an extension part Y2extends in the direction of the front housing30, and the extension part Y2is in contact with the front housing30to connect the reference ground.

A length of the preset portion B1and a length of the extension part Y1along a direction of the third frame segment12cboth exceed a preset length, and a length of the preset portion B2and a length of the extension part Y2along a direction of the fourth frame segment12dboth exceed a preset length, for example, both exceed ⅓ of a length of the first long frame102aor the second long frame102bof the metal frame10. Thus, the extension part Y1of the third frame segment12cand the extension part Y2of the fourth frame segment12dabut against the front housing30in a large area, so that while grounding is achieved, the front housing30is supported, thereby enhancing the stability of the overall structure.

As shown inFIG.1, an end close to an end portion of the first frame segment12aforming the third antenna body ANT2is connected to the radio frequency source S1, and the other end of the first frame segment12ais grounded. The other end of the first frame segment12aextends inward, that is, the other end of the first frame segment12aextends towards the direction of the front housing30(i.e., a black part between the first frame segment12aand the front housing30inFIG.1) to be in contact with the front housing30to thereby realize grounding, thus forming a complete feed circuit. Specifically, the radio frequency source S1is connected at a position close to the end portion of the end of the first frame segment12aadjacent to the gap11b, and the other end of the first frame segment12aadjacent to the gap11ais grounded.

An end close to an end portion of the fifth frame segment12eforming the fifth antenna body ANT4is connected to the radio frequency source S1, and the other end of the fifth frame segment12eis grounded. The other end of the fifth frame segment12eextends inward, that is, the other end of the fifth frame segment12eextends towards the direction of the front housing30(i.e., a black part between the fifth frame segment12eand the front housing30inFIG.1) to be in contact with the front housing30to thereby realize grounding, thus forming a complete feed circuit. Specifically, the radio frequency source S1is connected at a position close to the end portion of the end of the fifth frame segment12eadjacent to the gap11d, and the other end of the fifth frame segment12eadjacent to the gap11eis grounded.

An end close to an end portion of the second frame segment12bforming the sixth antenna body ANT5is connected to the radio frequency source S1, and the other end of the second frame segment12bis grounded. The other end of the second frame segment12bextends inward, that is, the other end of the second frame segment12bextends towards the direction of the front housing30(i.e., a black part between the second frame segment12band the front housing30inFIG.1) to be in contact with the front housing30to thereby realize grounding, thus forming a complete feed circuit. Specifically, the radio frequency source S1is connected at a position close to the end portion of the end of the second frame segment12badjacent to the gap11f, and the other end of the second frame segment12badjacent to the gap11bis grounded.

An end close to an end portion of the sixth frame segment12fforming the seventh antenna body ANT6is connected to the radio frequency source S1, and the other end of the sixth frame segment12fis grounded. The other end of the sixth frame segment12fextends inward, that is, the other end of the sixth frame segment12fextends towards the direction of the front housing30(i.e., a black part between the sixth frame segment12fand the front housing30inFIG.1) to be in contact with the front housing30to thereby realize grounding, thus forming a complete feed circuit. Specifically, the radio frequency source S1is connected at a position close to the end portion of the end of the sixth frame segment12fadjacent to the gap11a, and the other end of the sixth frame segment12fadjacent to the gap11dis grounded.

That is, the first frame segment12a, the fifth frame segment12e, the second frame segment12b, and the sixth frame segment12feach are connected to the radio frequency source S1at one end close to the end portion, and each are grounded at the other end.

The first frame segment12a, the fifth frame segment12e, the second frame segment12band the sixth frame segment12feach have a certain length in a direction perpendicular to the extension direction, and can be in contact with the front housing30to increase the overall structural strength.

In the present disclosure, as shown inFIG.1, a tuning switch (SW) K1is connected between all radio frequency sources S1and the corresponding frame segment12, that is, each of the radio frequency sources S1is connected to the corresponding frame segment12through a frequency modulation switch K1.

As shown inFIG.1, a position of the first antenna body ANT0located between the radio frequency source S1and the preset portion B2is grounded through a frequency modulation switch K2. A position of the second antenna body ANT1located at a side of the radio frequency source S1away from the preset portion B1is grounded, that is, the position of the second antenna body ANT1between the radio frequency source S1and the gap11cis grounded through a frequency modulation switch K3.

Specifically, all radio frequency sources S1and all frequency modulation switches K1, K2and K3are disposed on the main board20, the frequency modulation switch K2is connected to a ground between the first antenna body ANT0and the main board20to achieve grounding, and the frequency modulation switch K3is connected to a ground between the second antenna body ANT1and the main board20to achieve grounding. The attached drawings of the present disclosure are only schematic views. For example, actual positions of the radio frequency source S1and frequency modulation switch K1connected to the frame segment12corresponding to the second short frame101bshould be located on the main board20, however, in order to illustrate more clearly, they are drawn outside the main board20. In fact, for the frame segment12far from the main board20, the frame segment12and the radio frequency source S1on the main board20may be electrically connected through wires, resilient sheets, etc.

The ground on the main board20is connected to the front housing to form a common ground.

The frequency modulation switches K1, K2and K3all are switches connected to frequency modulation elements such as capacitors and/or inductors, and the frequency modulation switches K1, K2and K3play a matching role, that is, matching circuits.

The frequency modulation switches K1, K2and K3all belong to structures of antenna device200. That is, the antenna device200may include the aforementioned metal frame10, the antenna body21, the radio frequency sources S1, the frequency modulation switches K1, K2and K3, etc.

FIG.9illustrates an equivalent schematic diagram of a feeding structure of the first antenna body ANT0according to an embodiment of the disclosure. As shown inFIG.9, the radio frequency source S1corresponding to the first antenna body ANT0is connected to one end of the first antenna body ANT0through the tuning switch K1, and the other end of the first antenna body ANT0is directly grounded, that is, the other end of the first antenna body ANT0is grounded through the preset portion B1being connected to the front housing30; and the frequency modulation switch K2located between a connection position of the radio frequency source S1and the first antenna body ANT0and a grounded position at the other end of the first antenna body ANT0is grounded. Thus, the excitation signal generated by the radio frequency source S1can be grounded through the frequency modulation switch K2, and also directly grounded through the other end of the first antenna body ANT0to form a multi-circuit feed path, thereby realizing an antenna structure covering the three frequency bands of LB+MHB MIMO2+N41.

In some embodiments, the electronic device100may further include an insulating layer covering the periphery of the metal frame10, the insulating layer is composed of insulating materials, which is used to block the gaps of the metal frame10to improve the appearance consistency. Since the insulating layer is composed of insulating materials, it will not affect the radiation of the antenna signal. The insulating layer and the metal frame10together constitute the frame of the electronic device100.

In other embodiments, some frame segments12of the multiple frame segments12are connected to radio frequency source S1, and at least one frame segment12is not connected to radio frequency source S1. That is, in other embodiments, only some of the multiple frame segments12are connected to the radio frequency source S1.

The frame segment12not connected to the radio frequency source S1is grounded, and the frame segment12not connected to the radio frequency source S1is coupled with the adjacent frame segment12connected to the radio frequency source S1, which is used as a reinforced antenna body or a parasitic antenna body of the antenna body formed by the frame segment connected to the radio frequency source S1.

Thus, in other embodiments, some of the frame segments12of multiple frame segments12are connected to the radio frequency source S1, the at least one frame segment12is not connected to the radio frequency source S1, and the frame segment12not connected to the radio frequency source S1is coupled with the adjacent frame segment12connected to the radio frequency source S1, to thereby be used as the reinforced antenna body or the parasitic antenna body of the antenna body formed by the frame segment connected to the radio frequency source, in this situation, the number of radio frequency sources can be reduced, and the antenna performance can be improved or the antenna frequency bands ban be increased.

The electronic device100may further include structures such as a display screen and a glass cover plate. Since the electronic device100is not related to the improvement of the present disclosure, the electronic device100is not described and illustrated. For example, the cross-sectional views shown inFIG.1and the like are schematic views without the structures such as the display screen and the glass cover plate, and merely illustrate the component structures involved in the present disclosure.

The electronic device100may be a mobile phone or a tablet computer.

The electronic device100and antenna device200provided in the present disclosure can support the frequency bands under multiple communication standards including 5G NSA, 5G SA, WIFI, GPS and 2/3/4G by taking multiple frame segments of the metal frame10as the antenna bodies, meeting the communication requirements. The at least one gap is defined at the bottom of the electronic device100of the metal frame10, the gap of the metal frame10at the bottom of the side of the electronic device100can be reduced or avoided, so as to avoid the impact caused by being held by the user during use. In addition, compared with the existing architecture that requires six antennas under the 5G NSA communication standard, the present disclosure can reduce one antenna body, which is more conducive to the overall layout of the antenna, reduce the deployment of antennas on the main board20, reduce the cost, and improve the overall performance of the antenna.
