When the included angle θ is within the second predetermined range, the first side 111 and the third side 113 are away from each other, so that the electric field radiation region of the second radiator 150 is also away from the electric field radiation region of the first radiator 140, the isolation between the first radiator 140 and the second radiator 150 is relatively large, and the interference between the second radiator 150 and the first radiator 140 is relatively small.

In the electronic device 10 of the embodiment of the application, the second adjusting circuit 600 is electrically connected to the second portion 155, and since the second portion 155 is not easily held by a hand of a user, the interference on the second portion 155 electrically connected to the second adjusting circuit 600 is small; meanwhile, the second adjusting circuit 600 is electrically connected to the second portion 155, and the second adjusting circuit 600 can more easily change the capacitance and inductance values connected to the second portion 155, so that the second adjusting circuit 600 can more easily form the electric field strong point of the second radiator 150 on the second portion 155.

In addition, the electronic device 10 according to the embodiment of the present application may also adjust the capacitance and the inductance of the first adjusting circuit 300 to form the current zero point of the second radiator 150 in the second portion 155; the electronic device 10 may also form the current zero of the second radiator 150 at the second portion 155 by turning off the first adjusting circuit 300.

It should be noted that, in the electronic device 10 according to the embodiment of the present application, the first adjusting circuit 300 and the second adjusting circuit 600 may work together. That is, when the angle of the included angle θ is within the second predetermined range, the first adjusting circuit 300 and the second adjusting circuit 600 may jointly concentrate the current flowing through the second radiator 150 on the second portion 155, in which the first adjusting circuit 300 is adjusted mainly and the second adjusting circuit 600 is adjusted secondarily. When the included angle θ is within a first predetermined range, the first adjusting circuit 300 and the second adjusting circuit 600 may concentrate the current flowing through the second radiator 150 to the first portion 154, in which the adjustment of the second adjusting circuit 600 is mainly performed and the adjustment of the first adjusting circuit 300 is assisted.

Referring to fig. 7 again, the second portion 155 of the second radiator 150 according to an embodiment of the present invention may include a first sub-portion 1551 and a second sub-portion 1552 which are spaced apart from each other, the first sub-portion 1551 may be integrally connected to the first portion 154 of the second radiator 150, a first gap 1553 may be disposed between the second sub-portion 1552 and the first sub-portion 1551, a first ground point 152 may be disposed at an end of the first sub-portion 1551 away from the first gap 1553, the first sub-portion 1551 may be grounded by the first ground point 152, a second ground point 156 may be disposed at an end of the second sub-portion 1552 away from the first gap 1553, and the second sub-portion 1552 may be grounded by the second ground point 156, such that two free ends of the first sub-portion 1551 and the second sub-portion 1552 are disposed opposite to each other.

It is understood that the first feeding point 151 may be disposed at the first part 154 of the second radiator 150, the first sub-part 1551, or a connection of the first part 154 and the first sub-part 1551, so that the first feed 400 may be electrically connected to the first part 154 of the second radiator 150, the first sub-part 1551, or a connection of the first part 154 and the first sub-part 1551.

In the electronic device 10 of the embodiment of the application, the first feed 400 is connected to the first part 154 or the first sub-part 1551, and when the foldable body is in the folded state, the first feed 400 can feed a first excitation signal to the first part 154 or the first sub-part 1551, so that the first adjusting circuit 300 can concentrate the current flowing through the second radiator 150 on the first part 154.

In the electronic device 10 of the embodiment of the application, when the angle of the included angle θ is within the second preset range, the radiation branch from the first feeding point 151 to the end of the first sub-part 1551 close to the first gap 1553 may generate a first working mode; the radiation branch between the first feeding point 151 and the second electrical connection point 157 can generate a second working mode through electromagnetic coupling; the radiation branch between the first feeding point 151 and the second grounding point 156 can generate a third operation mode through electromagnetic coupling. Therefore, when the angle of the included angle θ is within the second preset range, the second radiator 150 of the present application may radiate a radio signal of a wider frequency band, and the frequency band range of the radio signal transmitted by the second radiator 150 may be expanded.

For example, referring to fig. 8 to fig. 10 in combination with fig. 7, fig. 8 is a schematic view of a first mode of current generated by the second radiator shown in fig. 7, fig. 9 is a schematic view of a second mode of current generated by the second radiator shown in fig. 7, and fig. 10 is a schematic view of a third mode of current generated by the second radiator shown in fig. 7. When the first feed 400 feeds the first excitation signal to the second radiator 150, the second adjusting circuit 600 or the second adjusting circuit 600 and the first adjusting circuit 300 together change the capacitance and inductance values electrically connected to the second radiator 150, so that the second radiator 150 can transmit wireless signals of different frequencies.

As shown in fig. 7 and 8, when the first feed 400 feeds the first excitation signal to the second radiator 150, a radiation branch from the first feeding point 151 of the second radiator 150 to an end of the first sub-portion 1551 close to the first slot 1553 may generate a first operating mode and may resonate an operating frequency band of an antenna mode operating at a quarter wavelength. The current I21 flows in the second radiator 150 and is mainly concentrated in the area of the first feeding point 151 to the first subsection 1551. An end portion (point a shown in fig. 8) of the first sub-part 1551 close to the first slot 1553 may be a current zero point of the current I21, the current I21 may flow from the first feeding point 151 connected to the first feed 400 to a direction in which the first slot 1553 is located, so that a first electric field formed by the current I21 is formed in a region in which the first part 154 is located to the first sub-part 1551, an electric field intensity point of the first electric field is formed in the current zero point of the current I21, that is, in a region near the first slot 1553, and the first electric field is concentrated near the third side 113 of the bottom of the electronic device 10.

As shown in fig. 9, when the first feed 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the first feeding point 151 and the second electrical connection point 157 of the second radiator 150 may generate the second operating mode through electromagnetic coupling and may resonate in the operating frequency band of the antenna mode operating at one-half wavelength. The current I22 flows in the second radiator 150 and is mainly concentrated in the area where the second electrical connection point 157 of the first feeding point 151 to the second subsection 1552 is located. A current zero point (point B shown in fig. 9, which is formed in the second sub-portion 1552 and is close to the first slot 1553) exists in a region where the second electrical connection point 157 of the first feeding point 151 to the second sub-portion 1552 is located, and the current I22 may flow to the current zero point B from the first feeding point 151 connected to the first feed 400 and the second electrical connection point 157 connected to the second adjusting circuit 600, respectively. Thus, a second electric field formed by the current I22 is formed in the region where the second electrical connection point 157 of the first feeding point 151 to the second sub-part 1552 is located, an electric field intensity point of the second electric field is formed at the current zero point B of the current I22, that is, in the region near the first slot 1553 to the second electrical connection point 157, and the second electric field is concentrated near the third side 113 of the bottom of the electronic device 10.

As shown in fig. 10, when the first feed 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the first feeding point 151 and the second grounding point 156 of the second radiator 150 may generate a third operating mode through electromagnetic coupling and may resonate in an operating frequency band of an antenna mode with one wavelength. The current I23 flows in the second radiator 150 and is mainly concentrated in the area where the first feeding point 151 is to the second grounding point 156 of the second sub-part 1552. Two current zero points (e.g., points C and D shown in fig. 10, the point C being formed at the second sub-portion 1552 and near the end of the first slot 1553, and the point D being formed at the area of the second electrical connection point 157 electrically connected to the second adjusting circuit 600) exist in the area where the second grounding point 156 from the first feeding point 151 to the second sub-portion 1552, the current I23 may flow from the first feeding point 151 to the current zero point C, the current zero point C to the current zero point D, the second grounding point 156 to the current zero point D, thus, a third electric field formed by the current I23 is formed in a region where the first feeding point 151 is located to the second ground point 156 of the second sub-portion 1552, electric field intensity points of the second electric field are formed at the current zero points C and D of the current I23, that is, in the vicinity of the first slit 1553, the second electrical connection point 157, and the third electric field is concentrated in the vicinity of the third side 113 of the bottom of the electronic device 10.

In the electronic device 10 according to the embodiment of the application, under the action of the second adjusting circuit 600 or the first adjusting circuit 300 and the second adjusting circuit 600, when the included angle θ is within the second preset range, the second radiator 150 may radiate the three operating modes, so that the second radiator 150 may transmit the wireless signal in the wider frequency band.

For example, referring to fig. 11, fig. 11 is a graph of isolation when the second radiator shown in fig. 7 transmits the first excitation signal. The curve S1 is an isolation curve when the first adjustment circuit 300 has an inductance value of 3 nanohenries (nH) and the second radiator 150 transmits the first excitation signal when the second adjustment circuit 600 is turned off. The curve S2 is an isolation curve when the first radiator 150 transmits the first excitation signal when the inductance value of the first adjusting circuit 300 is 5 nanohenries (nH) and the inductance value of the second adjusting circuit 600 is 3 nanohenries (nH). The curve S3 is an isolation curve when the first adjusting circuit 300 and the second adjusting circuit 600 are all turned off, and the second radiator 150 transmits the first excitation signal.

As can be seen from the curve S1, the isolation of the second radiator 150 at a frequency of 1.9GHz (1900MHz) is-17, which is better, and the second radiator 150 can transmit a wireless signal of 1.9 GHz. As can be seen from the curve S2, the isolation of the second radiator 150 is-19 at a frequency of 2.3GHz (2300MHz), which is better, and the second radiator 150 can transmit a wireless signal of 2.3 GHz. As can be seen from the curve S3, the isolation of the second radiator 150 is-31 at the frequency of 2.6GHz (27000MHz), which is better, and the second radiator 150 can transmit the wireless signal of 2.6 GHz.

As can be seen from the curves S1 to S3, the second radiator 150 can cover the wireless signals of 1900MHz to 2700MHz under the action of the first adjusting circuit 300 and the second adjusting circuit 600. Therefore, the second radiator 150 according to the embodiment of the present application may transmit the medium-high frequency radio frequency signals from 1710MHz to 2690MHz, and the second radiator 150 has a better isolation when transmitting the medium-high frequency radio frequency signals.

It should be noted that, the above are only some exemplary operating modes of the second radiator 150, and when the angle θ is within the second preset range, the second radiator 150 may also radiate other operating modes by adjusting the inductance and the capacitance of the first adjusting circuit 300 and the second adjusting circuit 600. The working mode of the second radiator 150 in the extended state is not limited in the embodiment of the present application.

In the electronic device 10 of the embodiment of the application, the second portion 155 of the second radiator 150 includes the first sub-portion 1551 and the second sub-portion 1552, and when the included angle θ is within a first preset range, the first portion 154 may generate a fourth working mode; the radiating branches of first portion 154 to first portion 154 may produce a fifth mode of operation. Therefore, when the angle of the included angle θ is within the first preset range, the second radiator 150 according to the embodiment of the present application may radiate a radio signal in a wider frequency band, and the frequency band range of the radio signal transmitted by the second radiator 150 may be expanded.

For example, please refer to fig. 12 to fig. 13 in combination with fig. 7, fig. 12 is a schematic current diagram of a fourth mode generated by the second radiator shown in fig. 7, and fig. 13 is a schematic current diagram of a fifth mode generated by the second radiator shown in fig. 7. When the first feed 400 feeds the first excitation signal to the second radiator 150, the first adjusting circuit 300 or the first adjusting circuit 300 and the second adjusting circuit 600 together change the capacitance and the inductance value electrically connected to the second radiator 150, so that the second radiator 150 can transmit wireless signals of different frequencies.

As shown in fig. 12, when the first feed 400 feeds the first excitation signal to the second radiator 150, a radiation branch between an end of the first part 154 of the second radiator 150, which is far away from the first sub-part 1551, and the first feeding point 151 may generate a fourth operating mode and may resonate an operating frequency band of an antenna mode operating in a lateral quarter wavelength. The current I24 flows in the second radiator 150 and is mainly concentrated in the area from the end of the first part 154 remote from the first sub-part 1551 to the first feeding point 151. An end (e.g., point E shown in fig. 12) of the first portion 154 away from the first feeding point 151 may be a current zero point of the current I24, the current I24 may flow from the first feeding point 151 to a direction in which an end of the first portion 154 of the second radiator 150 away from the first sub-portion 1551 is located, so that a fourth electric field formed by the current I24 is formed in a region from the first portion 154 to the first feeding point 151, an electric field strength point of the fourth electric field is formed in the current zero point of the current I24, that is, a region away from the first feeding point 151 in the first portion 154, and the fourth electric field is concentrated near the lateral second edge 112 of the electronic device 10.

As shown in fig. 13, when the first feed 400 feeds the first excitation signal to the second radiator 150, the radiation branches between the ends of the first part 154 to the first sub-part 1551 of the second radiator 150 close to the first slot 1553 may generate a fifth operation mode and may resonate an operation band of an antenna mode operating at a lateral half wavelength. The current I25 flows in the second radiator 150 and is mainly concentrated in the area from the first part 154 to the first sub-part 1551. A current zero point exists in the region from the first portion 154 to the first sub-portion 1551 (point F is shown in fig. 13, and point F is formed in the region where the first portion 154 is connected to the first sub-portion 1551), and the current I25 may flow from the end away from the current zero point of the first portion 154 and the end away from the current zero point of the first sub-portion 1551 respectively. Thus, a fifth electric field formed by the current I25 is formed in the region where the first part 154 to the first sub-part 1551 are located, an electric field intensity point of the fifth electric field is formed at the current zero point F of the current I25, that is, in the region where the first part 154 is connected to the first sub-part 1551, and the fifth electric field is concentrated near the lateral second side 112 of the electronic device 10 and near the bottom third side 113.

In the electronic device 10 according to the embodiment of the application, under the action of the first adjusting circuit 300 and/or the second adjusting circuit 600, when the angle of the included angle θ is within the first preset range, the second radiator 150 may radiate the two operating modes, so that the second radiator 150 may transmit the wireless signal in the wider frequency band.

Moreover, when the angle of the included angle θ is within the first preset range, the second radiator 150 according to the embodiment of the present application may also transmit medium-high frequency radio frequency signals from 1710MHz to 2690MHz, and the second radiator 150 also has a better isolation degree when transmitting the medium-high frequency radio frequency signals. Thus, the second radiator 150 can transmit the wireless signal of the same frequency band when the foldable body 100 is in the unfolded state and the folded state.

It is understood that the above are only some exemplary operation modes of the second radiator 150, and when the angle θ is within the first preset range, the second radiator 150 may also radiate other operation modes by adjusting the inductance and capacitance values of the first adjusting circuit 300 and the second adjusting circuit 600. The working mode of the second radiator 150 in the folded state is not limited in the embodiment of the present application.

In the electronic device 10 according to the embodiment of the present application, when the first radiator 140 transmits the first excitation signal, each frequency band has two working modes, namely, a bottom working mode and a side working mode. For example, as can be seen from fig. 8 and 12, the first radiator 140 has two quarter-wavelength operation modes, i.e., a bottom mode and a side mode; as can be seen from fig. 9 and 13, the first radiator 140 has two operating modes of one-half wavelength on the bottom and the side. Accordingly, the electronic device 10 may control the first adjusting circuit 300 and the second adjusting circuit according to the folded state or the unfolded state of the foldable body 100, so that the second radiator 150 may excite the side working mode when the foldable body 100 is folded, and the second radiator 150 may excite the bottom working mode when the foldable body 100 is folded and unfolded, and further, when the electronic device 10 is in different forms, the second radiator 150 has better radiation performance.

When the included angle θ is within the first predetermined range, the second radiator 150 according to the embodiment of the present disclosure may radiate a side working mode, so as to reduce interference between the second radiator 150 and the first radiator 140 in a folded state. For example, referring to fig. 14 and 15, fig. 14 is a graph illustrating an isolation curve between the first radiator and the second radiator in the bottom radiation mode of the second radiator, and fig. 15 is a graph illustrating an isolation curve between the first radiator and the second radiator in the side radiation mode of the second radiator.

As shown in fig. 14, a curve S4 is a graph of the reflection coefficient of the second radiator 150 when the second radiator 150 radiates the bottom operating mode; the curve S5 is a graph of the reflection coefficient of the first radiator 140 when in operation. Curve S6 is a graph of the isolation of the first radiator 140 from the second radiator 150. As can be seen from the curves S4 and S6, when the first radiator 140 is in the frequency band of 1.575GHz, the isolation between the first radiator 140 and the second radiator 150 is-10 dB; the first radiator 140 has-7 dB isolation from the second radiator 150 in the 2.4GHz band. As can be seen from the curves S5 and S6, when the second radiator 150 is in the frequency band of 2.1GHz, the isolation between the second radiator 150 and the second radiator is-11 dB; the first radiator 140 has-10 dB isolation from the second radiator 150 in a frequency band of about 2.6 GHz.

As shown in fig. 15, the curve S7 shows a reflection coefficient curve of the second radiator 150 in the side working mode of radiation of the second radiator 150; the curve S8 is a graph of the reflection coefficient of the first radiator 140 when in operation. Curve S9 is a graph of the isolation of the first radiator 140 from the second radiator 150. It can be seen from the curves S7 and S9 that the isolation between the first radiator 140 and the second radiator 150 is-12 dB at the frequency band of 1.575 GHz; the first radiator 140 has-11 dB isolation from the second radiator 150 in the 2.4GHz band. As can be seen from the curves S8 and S6, when the second radiator 150 is in the 2.1GHz band, the isolation between the second radiator 150 and the second radiator is-13 dB; when the first radiator 140 is in a frequency band of about 2.6GHz, the isolation between the first radiator 140 and the second radiator 150 is-17 dB.

Comparing the curves S6 and S9, it can be seen that the isolation between the second radiator 150 and the first radiator 140 is greater when the second radiator is in the side-edge mode of operation in the same frequency band. For example, in the frequency band of 1.575GHz, the isolation between the first radiator 140 and the second radiator 150 in the curve S6 is only-10 dB, while the isolation between the first radiator 140 and the second radiator 150 in the curve S7 may be-12 dB, and obviously, the isolation between the second radiator 150 and the first radiator 140 is larger when the second radiator 150 is in the side operating mode.

In the electronic device 10 according to the embodiment of the application, when the angle of the included angle θ is within the first preset range, the second radiator 150 may radiate a side working mode, the electric field radiation region of the second radiator 150 is not in the same region as the electric field radiation region of the first radiator 140, so that the isolation between the first radiator 140 and the second radiator 150 is improved, and the interference between the second radiator 150 and the first radiator 140 is small.

The electronic device 10 may control the operation mode of the second radiator 150 through the first adjusting circuit 300 and the second adjusting circuit 600, and may also implement the control in other manners. For example, please refer to fig. 16, where fig. 16 is a schematic diagram illustrating a fifth structure of an electronic device according to an embodiment of the present application. The electronic device 10 may further include a third adjusting circuit 700, the third adjusting circuit 700 may be electrically connected to the second sub-portion 1552, a third electrical connection point 159 may be disposed on the second sub-portion 1552, and the third electrical connection point 159 may be disposed between the first ground point 152 and the second electrical connection point 157, so that the third adjusting circuit 700 is closer to the first slit 1553 than the second adjusting circuit 600.

It is understood that the third regulating circuit 700 may include one or more of an inductor, a capacitor. The plurality of inductors and the plurality of capacitors can be connected in parallel, in series, in part in series or in part in parallel. The third adjusting circuit 700 may change the capacitance and inductance values connected to the second sub-portion 1552 of the second radiator 150 to change the current zero point of the current flowing through the second radiator 150.

It can be understood that the third adjusting circuit 700 and the second adjusting circuit 600 are electrically connected to the second sub-portion 1552, and the third adjusting circuit 700 and the second adjusting circuit 600 can adjust the bottom operating mode of the second radiator 150 together, so that the second radiator 150 can adjust more bottom operating modes, and thus can cover more operating frequency bands.

With continuing reference to fig. 7, the electronic device 10 may further include a second feed 800, wherein the second feed 800 may be electrically connected to a second sub-portion 1552, wherein the second feed 800 may provide a second excitation signal and may feed the second excitation signal to the second sub-portion 1552.

It will be appreciated that a second feedpoint 158 may be provided on the second sub-part 1552 and that the second feed 800 may be electrically connected to the second feedpoint 158 of the second sub-part 1552. The second feeding point 158 may be disposed between the second electrical connection point 157 and the second ground point 156. Thus, when the second feed 800 feeds the second excitation signal to the second subsection 1552, current may return to ground from the second ground point 156 and the second subsection 1552 may radiate the second excitation signal.

It is to be understood that the second excitation signal may be a low frequency signal. That is, the second sub-portion 1552 may also transmit low frequency signals, which may range in frequency between 703MHz to 960 MHz.

In the electronic device 10 of the embodiment of the application, the first feed 400 is disposed between the first part 154 and the first sub-part 1551 of the second radiator 150, the second feed 800 is disposed on the second sub-part 1552, and the first part 154, the first sub-part 1551, and the second sub-part 1552 of the second radiator 150 may transmit medium-high frequency radio frequency signals; the second sub-portion 1552 of the second radiator 150 may transmit low frequency radio frequency signals. Therefore, the second radiator 150 can transmit the medium-high frequency rf signal and the low-frequency rf signal, and the second radiator 150 realizes multiplexing, which can save the space occupied by the radiator in the electronic device 10.

Please refer to fig. 17, where fig. 17 is a schematic diagram illustrating a sixth structure of an electronic device according to an embodiment of the present application. The first antenna radiator may include a third portion 141, a fourth portion 142, and a fifth portion 143. The third portion 141 is disposed on the second side 112, the fourth portion 142 can be disposed on the first side 111, and the fourth portion 142 and the third portion 141 are integrally connected to form an "L" shaped structure; the fifth portion 143 is disposed on the first side 111, a second gap 144 is disposed between the fifth portion 143 and the fourth portion 142, and a free end of the fifth portion 143 and a free end of the fourth portion 142 may be disposed opposite to each other.

It is understood that the third portion 141 is disposed on the second side 112, which means that the third portion 141 is disposed on the outer edge of the second side 112, and also means that the third portion 141 is disposed inside the foldable body 100 corresponding to the second side 112. Similarly, the fourth portion 142 and the fifth portion 143 are disposed on the first edge 111, which means that the fourth portion 142 and the fifth portion 143 are disposed on the outer edge of the first edge 111, or the fourth portion 142 and the fifth portion 143 are disposed inside the foldable body 100 corresponding to the first edge 111.

It is understood that the third portion 141 of the first radiator 140 and the first portion 154 of the second radiator 150 may be disposed opposite to the second side 112, i.e., a third slot 145 may be disposed on the second side 112, and the third slot 145 may enable the second side 112 to form two free ends, which may form the third portion 141 and the first portion 154, respectively.

It is to be understood that a third grounding point 146 and a fourth grounding point 147 may be disposed on the first radiator 140, wherein the third grounding point 146 may be disposed on an end of the third portion 141 remote from the fourth portion 142, and the third portion 141 is grounded via the third grounding point 146. A fourth grounding point 147 may be provided at an end of the fifth portion 143 remote from the second gap 144, the fifth portion 143 being grounded via the fourth grounding point 147. The positions of the third grounding point 146 and the fourth grounding point 147 in this embodiment can make the radiation branch of the first radiator 140 longer, which is more beneficial for the first radiator 140 to adjust the frequency band of the transmitted wireless signal.

It is understood that the third feeding point 148 may be disposed on the third, fourth or

fifth portions

141, 142, 143 of the first radiator 140, and the third feed 500 may be electrically connected to the third feeding point 148 to feed signals to the first radiator 140.
