The terms "first," "second," "third," and the like in this disclosure are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", "a third", etc. may include at least one such feature, either explicitly or implicitly.

The first radiator 10 may be, but is not limited to being, an LDS radiator, or an FPC radiator, or a PDS radiator, or a metal branch radiator. The shape, structure and material of the first radiator 10 are not particularly limited, and the shape of the first radiator 10 includes, but is not limited to, a bent shape, a strip shape, a sheet shape, a rod shape, a coating, a film, etc. When the first radiator 10 is in a strip shape, the extending track of the first radiator 10 may not be limited, so the first radiator 10 may extend along a straight line, a curved line, a multi-section bending track, or the like. The first radiator 10 may be a line with a uniform width on the extending track, or may be a bar with a gradual width change and a widening area with an unequal width.

The first radiator 10 has a first free end 11, a feed point (e.g., a first feed point 12) and a first ground point 13. The first grounding point 13 is electrically connected to the ground by, but not limited to, direct electrical connection (such as soldering), or indirect electrical connection by means of coaxial lines, microstrip lines, radio frequency lines, conductive clips, conductive adhesives, insert metals, etc. The feeding point, for example the first feeding point 12, may be located between the first free end 11 and the first ground point 13. It will be appreciated that the specific location of the feeding point, e.g. the first feeding point 12, on the first radiator 10 may not be limited.

In some embodiments, the first radiator 10 is further provided with a first end 14. In some embodiments, the first end 14 is located on a side of the first ground point 13 remote from the feed point, e.g., the first feed point 12. In some embodiments, the first end 14 is provided with a first ground point 13, i.e. the first ground point 13 is located at the first end 14. In some embodiments, the radiating portion of the first radiator 10 between the first ground point 13 and the first end 14 may be omitted such that the first ground point 13 is at the end.

In some embodiments, the two ends of the first radiator 10 (e.g., the first free end 11 and the first end 14, such as the first free end 11 and the first ground point 13) may each have a gap between other components. In some scenarios, when the antenna assembly 100 is applied in an electronic device, the two ends of the first radiator 10 may not be easily held or blocked at the same time with gaps (i.e., two gaps) respectively provided between other components in the electronic device. Even when one of the two slots is blocked, the first radiator 10 can transmit and receive electromagnetic wave signals, and thus the antenna assembly 100 has good communication performance.

Referring to fig. 1, the second radiator 20 has a second free end 21, a feeding point (e.g., a second feeding point 22) and a second grounding point 23. The second grounding point 23 is electrically connected to the ground by, but not limited to, direct electrical connection (such as soldering), or indirect electrical connection by means of coaxial lines, microstrip lines, radio frequency lines, conductive clips, conductive adhesives, insert metals, etc. The feeding point, for example the second feeding point 22, may be located between the second free end 21 and the second ground point 23. It will be appreciated that the specific location of the feeding point, e.g. the second feeding point 22, on the second radiator 20 may not be limited.

In some embodiments, the two ends of the second radiator 20 (e.g., the second free end 11 and the second end 24, such as the second free end 11 and the second ground point 23) may each have a gap between the other components. In some scenarios, when the antenna assembly 100 is applied in an electronic device, the two ends of the second radiator 20 may not be easily held or blocked at the same time with gaps (i.e., two gaps) respectively provided between other components in the electronic device. Even when one of the two slots is blocked, the second radiator 20 can transmit and receive electromagnetic wave signals, and thus the antenna assembly 100 has good communication performance.

Referring to fig. 1, the first feed 30 may be indirectly connected to a feeding point, for example, the first feeding point 12, through a first matching circuit 40. The first feed 30 may energize the first radiator 10 to support at least one of a GPS band, a WiFi band, a low frequency band, a medium high frequency band, an NR (new air interface) band.

In some embodiments, the first resonant mode is a 1/4 wavelength mode, and the 1/4 wavelength mode is a resonant mode with relatively high efficiency, so that the transceiving efficiency of the frequency band supported by the first resonant mode can be enhanced. In some embodiments, the first resonant mode is a 1/6 wavelength mode. In some embodiments, the first resonant mode is a 1/6-1/4 wavelength mode.

In some embodiments, the current I1 of the first resonant mode is distributed between the first free end 11 and the first ground point 13.

Referring to fig. 1, the first matching circuit 40 can be used to adjust the frequency of the first frequency band. In some embodiments, the first matching circuit 40 may be comprised of a switch control circuit and/or a load circuit, or may be comprised of an adjustable capacitance (which may be replaced by a fixed value capacitance) and/or an adjustable inductor (which may be replaced by a fixed value inductance).

In some embodiments, the second resonant mode is a 1/4 wavelength mode, and the 1/4 wavelength mode is a resonant mode with relatively high efficiency, so that the transceiving efficiency of the frequency band supported by the second resonant mode can be enhanced. In some embodiments, the second resonant mode is a 1/6 wavelength mode. In some embodiments, the second resonant mode is a 1/6-1/4 wavelength mode.

In some embodiments, the current I2 of the second resonant mode is distributed between the second free end 21 and the second ground point 23.

Referring to fig. 1, the frequency selection circuit 60 is electrically connected between a feeding point (e.g., the second feeding point 22) and the second feed 50. That is, the second feed 50 may be electrically connected to a feed point, such as the second feed point 22, through the frequency selective circuit 60. The frequency selective circuit 60 may be directly grounded.

The frequency selection circuit 60 may be used to adjust the frequency of the second frequency band. In some embodiments, the frequency selection circuit 60 may be comprised of a switch control circuit and/or a load circuit, or may be comprised of an adjustable capacitance (which may also be replaced by a fixed value capacitance) and/or an adjustable inductor.

Referring to fig. 1, a first radiator 10 and a second radiator 20 are capacitively coupled to each other so as to be in a capacitively coupled state. In some embodiments, the first radiator 10 and the second radiator 20 may be disposed side by side to capacitively couple to form a distributed capacitive coupling structure. The current I1 on the first radiator 10 is fed to the second radiator 20 in a capacitive coupling (capacitive coupling) manner, generating a current I3 so that the second radiator 20 supports the third frequency band under the excitation of the first feed 30. Further, the second radiator 20 may increase the overall system efficiency of the first feed 30 in the capacitively coupled state. In addition, the effect of widening the broadband can be achieved by the third frequency band. It can be understood that the current I2 on the second radiator 20 may also be fed to the first radiator 10 in a capacitive coupling manner, so as to increase the overall system efficiency of the second feed source 50, and details thereof will be referred to the description of the second radiator 20 increasing the overall system efficiency of the first feed source 30 in the capacitive coupling state.

In an embodiment, the third frequency band may include at least one of a GPS frequency band, a WiFi frequency band, a low frequency band, a medium and high frequency band, and an NR (new air interface) frequency band.

In one embodiment, the circuit for connecting the feeding point (e.g., the second feeding point 22) to ground in the frequency selection circuit 60 is turned on when the first feed 30 excites the second radiator 20 and turned off when the second feed 50 excites the second radiator 20, so as to improve the isolation between the first feed 30 and the second feed 50.

In an embodiment, the circuit for connecting the second radiator 20 and the feeding point (for example, the second feeding point 22) in the frequency selection circuit 60 is turned off when the first feed 30 excites the second radiator 20, and turned on when the second feed 50 excites the second radiator 20, so as to improve the isolation between the first feed 30 and the second feed 50.

It can be appreciated that the frequency selection circuit 60 may also adjust the frequency of the first frequency band and/or the frequency of the third frequency band when the first radiator 10 and the second radiator 20 are in the capacitive coupling state while improving the isolation between the first feed 30 and the second feed 50.

In some embodiments, the second matching circuit 61 and the first filtering circuit 62 may be used as a circuit in the frequency selection circuit 60 for communicating the second radiator 20 with the second feed 50. That is, the circuit composed of the second matching circuit 61 and the first filter circuit 62 is turned off when the first feed source 30 excites the second radiator 20, and is turned on when the second feed source 50 excites the second radiator 20, so that the isolation between the first feed source 30 and the second feed source 50 is improved. In some embodiments, the first filter circuit 62 is turned off when the first feed 30 excites the second radiator 20 and turned on when the second feed 50 excites the second radiator 20 to promote isolation between the first feed 30 and the second feed 50.

In some embodiments, the second filter circuit 63 may adjust the frequency of the first frequency band and/or the frequency of the third frequency band when the first radiator 10 and the second radiator 20 are in the capacitive coupling state.

In some embodiments, the second filter circuit 63 may be used as a circuit for connecting the second radiator 20 to the ground in the frequency selection circuit 60. That is, the second filter circuit 63 is turned on when the first feed 30 excites the second radiator 20 and turned off when the second feed 50 excites the second radiator 20 to improve isolation between the first feed 30 and the second feed 50.

In some embodiments, the second matching circuit 61 may be used to adjust the frequency of the second frequency band. In some embodiments, the second matching circuit 61 may be composed of a switch control circuit and/or a load circuit, or may be composed of an adjustable capacitance (which may also be replaced by a fixed capacitance) and/or an adjustable inductor.

In some embodiments, the first filter circuit 62 may include a first inductance L1 electrically connected between the feed point (e.g., the second feed point 22) and the first matching circuit 61 and a first capacitance C1 electrically connected between the feed point (e.g., the second feed point 22) and the first matching circuit 61.

The second capacitor C2 and the third inductor L3 may form a filter circuit.

Referring to fig. 3, fig. 3 is a schematic diagram of a frequency selection circuit 60 shown in fig. 2 in some embodiments. Wherein the second inductance L2 can be replaced by a third capacitance C3.

The second capacitor C2 is connected in parallel with the third inductance L3. The feeding point (for example, the second feeding point 22) is electrically connected to the third capacitor C3 through the second capacitor C2 and the third inductor L3, respectively. The second capacitor C2 and the third inductor L3 may form a filter circuit.

Referring to fig. 1, the first radiator 10 and the second radiator 20 may have a strip shape. The first end 14 and the second free end 21 may be located on a side of the first free end 11 and the second end 24, i.e. the first free end 11 and the second end 24 are located on a side of the first end 14 and the second free end 21.

In some embodiments, the orthographic projection of the first end 14 onto the second radiator 20 coincides with the second free end 21. In some embodiments, the orthographic projection of the first ground point 13 onto the second radiator 20 may coincide with the second free end 21. For example, the first ground point 13 is located at the first end 14, i.e. the first ground point 13 is terminated, and the orthographic projection of the first ground point 13 on the second radiator 20 may coincide with the second free end 21.

In some embodiments, the orthographic projection of the second free end 21 onto the first radiator 10 coincides with the first end 14. In some embodiments, the orthographic projection of the second free end 21 on the first radiator 10 may coincide with the first ground point 13. For example, in some scenarios, where the first ground point 13 is located at the first end 14, i.e., the first ground point 13 is terminal, then the orthographic projection of the second free end 21 onto the first radiator 10 may coincide with the first ground point 13.

In some embodiments, the orthographic projection of the second end 24 onto the first radiator 10 coincides with the first free end 11. In some embodiments, the orthographic projection of the second ground point 23 on the first radiator 10 may coincide with the first free end 11. For example, the second grounding point 23 is located at the second end 24, i.e. the second grounding point 23 is terminal, and the orthographic projection of the second grounding point 23 on the first radiator 10 coincides with the first free end 11.

In some embodiments, the orthographic projection of the first free end 11 onto the second radiator 20 coincides with the second end 24. In some embodiments, the orthographic projection of the first free end 11 on the second radiator 20 may coincide with the second ground point 23. For example, the second grounding point 23 is located at the second end 24, i.e. the second grounding point 23 is terminated, and the orthographic projection of the first free end 11 on the second radiator 20 may coincide with the second grounding point 23.

Referring to fig. 1, fig. 4 and fig. 5 together, fig. 4 is a schematic structural diagram of the antenna assembly 100 shown in fig. 1in another embodiment, and fig. 5 is a schematic structural diagram of the antenna assembly 100 shown in fig. 1in another embodiment. In fig. 4, the first radiator 10 and the second radiator 20 are in a capacitive coupling state, and the length of the mutually coupled branches is L1. The length L1 of the mutually coupled stubs can be adjusted when the first radiator 10 and the second radiator 20 are slid relatively. For example, the first radiator 10 moves toward the side near the second free end 21, increases the length L1 of the mutually coupled stubs, and can move to the capacitively coupled state in fig. 1. For example, the first radiator 10 moves to a side away from the second free end 21, reduces the stub length L1 of the mutual coupling, and can move to the non-capacitively coupled state in fig. 5.

In some embodiments, the first radiator 10 and the second radiator 20 in fig. 5 are in a non-capacitively coupled state, i.e., the current I1 on the first radiator 10 cannot be fed to the second radiator 20 in a capacitively coupled manner, and likewise, the current I2 on the second radiator 20 cannot be fed to the first radiator 10 in a capacitively coupled manner.

Referring to fig. 1 and fig. 6 together, fig. 6 is a schematic structural diagram of the antenna assembly 100 shown in fig. 1 in another embodiment. In fig. 6, the distance between the first radiator 10 and the second radiator 20 is L2, and the first radiator 10 and the second radiator 20 are in a non-capacitively coupled state. The distance L2 can be adjusted when the first radiator 10 and the second radiator 20 slide relatively. For example, the first radiator 10 moves away from the second radiator 20 in fig. 1, and increases the distance L2, and can move to the non-capacitively coupled state in fig. 6. For example, in fig. 6, the first radiator 10 moves toward the side close to the second radiator 20, and the distance L2 is reduced, so that the first radiator can move to the capacitively coupled state in fig. 1.

Referring to fig. 7, fig. 7 is a schematic diagram illustrating an antenna assembly 100 shown in fig. 1 in other embodiments. The first radiator 10 may be bent. The first free end 11 and the first end 14 may not be opposed in a straight direction. The first free end 11 and the first end 14 may be both ends of the first radiator 10. It will be appreciated that the first free end 11 and the first end 14 may be opposite ends of the first radiator 10 in the shape of a straight line.

The first radiator 10 may include a first portion 101 and a second portion 102 connected by bending. The first portion 101 may have a first free end 11 and the second portion 102 may have a first end 14. The first portion 101 is connected to the second portion 102, and the point of intersection is a first intersection 103. The first feeding point 12 is located at the first portion 101. The first ground point 13 is located at the second portion 102.

Referring to fig. 7, the second radiator 20 may be bent. The second free end 21 and the second end 24 may not be opposed in a straight direction. The second free end 21 and the second end 24 may be both ends of the second radiator 20. It will be appreciated that the second free end 21 and the second end 24 may be opposite ends of the second radiator 20 in the shape of a straight line.

The second radiator 20 may include a third portion 201 and a fourth portion 202 connected by a bend. The third portion 201 may have a second free end 21 and the fourth portion 202 may have a second end 24. The third portion 201 is connected to the fourth portion 202, and the point of intersection is the second intersection 203. The second feeding point 22 is located at the third section 201. The second ground point 23 is located at the fourth portion 302.

Referring to fig. 7, the first radiator 10 and the second radiator 20 are in a capacitively coupled state. In some embodiments, the direction of extension of the first portion 101 coincides with the direction of extension of the fourth portion 202. It will be appreciated that the direction of extension of the first portion 101 may also coincide with the direction of extension of the third portion 201. For example, the extending direction of the third portion 201 coincides with the extending direction of the fourth portion 202. For example, the extending direction of the first portion 101 coincides with the extending direction of the second portion 102, and the extending direction of the second portion 102 coincides with the extending direction of the third portion 201.

Referring to fig. 7, the first radiator 10 and the second radiator 20 are in a capacitively coupled state. In some embodiments, the direction of extension of the second portion 102 coincides with the direction of extension of the third portion 201. It will be appreciated that the direction of extension of the second portion 102 may also coincide with the direction of extension of the fourth portion 202. For example, the extending direction of the third portion 201 coincides with the extending direction of the fourth portion 202. For example, the extending direction of the second portion 102 coincides with the extending direction of the first portion 101, and the extending direction of the first portion 101 coincides with the extending direction of the fourth portion 202.

Referring to fig. 7, the extending direction of the first portion 101 and the extending direction of the fourth portion 202 are on different straight lines, so that the first portion 101 and the fourth portion 202 are disposed in parallel.

Referring to fig. 7, the extending direction of the second portion 102 and the extending direction of the third portion 201 are on different straight lines, so that the second portion 102 and the third portion 201 are disposed in parallel.

Referring to fig. 7, the first radiator 10 is capacitively coupled with the second radiator 20 at the first portion 101 and the second portion 102, respectively, so as to be in a capacitively coupled state. The second radiator 20 is capacitively coupled with the first radiator 10 at the third portion 201 and the fourth portion 202, respectively, to be in a capacitively coupled state. In some embodiments, the first radiator 10 may be capacitively coupled with the second radiator 20, e.g., the fourth portion 202, at least at the first portion 101, to be in a capacitively coupled state. In some embodiments, the first radiator 10 may be capacitively coupled with the second radiator 20, e.g., the third portion 201, at least at the second portion 102, to be in a capacitively coupled state. In some embodiments, the second radiator 20 may be capacitively coupled with the first radiator 10, e.g., the second portion 102, at least at the third portion 201, to be in a capacitively coupled state. In some embodiments, the second radiator 20 may be capacitively coupled with the first radiator 10, e.g., the fourth portion 202, at least at the first portion 101, to be in a capacitively coupled state.

It is understood that the first radiator 10 and the second radiator 20 in fig. 7 can also slide relatively as shown in fig. 4 and 6, and switch between the capacitive coupling state and the non-capacitive coupling state, which is not described herein.

In some cases, referring to fig. 8, fig. 8 is a schematic structural diagram of the antenna assembly 100 shown in fig. 7 in another embodiment. The first portion 101 is arranged at a side of the second portion 102 close to the second radiator 20. The first portion 101 extends toward the second radiator 20. The fourth portion 202 is arranged on the side of the third portion 201 close to the first radiator 10. The fourth portion 202 extends toward the second portion 102. The first radiator 10 and the second radiator 20 are in a non-capacitively coupled state. There is a fold line M between the first portion 101 and the second portion 102. The second radiator 20 is rotatable relative to the first radiator 10 about the fold line M and is rotatable to a capacitively coupled state of the first radiator 10 and the second radiator 20, for example as shown in fig. 7. That is, the first radiator 10 is also rotatable about the fold line M with respect to the second radiator 20, and is rotatable until the first radiator 10 and the second radiator 20 are in a capacitively coupled state. It will be appreciated that the arrangement of the first radiator 10 and the second radiator 20 is not limited to the state shown in fig. 8, but may be other types of states, and may be rotated about the fold line M by the second radiator 20 relative to the first radiator 10, and rotated to a state in which the first radiator 10 and the second radiator 20 are in capacitive coupling, such as the state shown in fig. 7. Or the first radiator 10 rotates about the fold line M with respect to the second radiator 20 and rotates to a state in which the first radiator 10 and the second radiator 20 are in capacitive coupling, such as the state shown in fig. 7.

Referring to fig. 9, fig. 9 is a graph of return loss versus frequency (GHz) on the horizontal axis and return loss (dB) on the vertical axis of the antenna assembly 100 of fig. 7 in some embodiments. Curve a is the return loss curve of the antenna assembly 100 under the first feed 10, curve B is the return loss curve of the antenna assembly 100 under the second feed 20, and curve C is the isolation curve of the antenna assembly 100 under the first feed 10 and the second feed 20.

Wherein, on the curve A, there is a first identification point (2.4704, -11.955) and a second identification point (2.3102, -12.663), on the curve A, the first identification point (2.4704, -11.955) can be a frequency band supported by the first resonance mode, and the second identification point (2.3102, -12.663) can be a frequency band supported by the third resonance mode. It can be seen that the antenna assembly 100 has good antenna performance at around 2.4GHz, i.e. the antenna assembly 100 has good antenna performance at around the first frequency band. Moreover, the matching of the first frequency band and the third frequency band may widen the bandwidth of the antenna assembly 100. Furthermore, the antenna assembly 100 has a good working state, and can meet engineering requirements. In addition, the bandwidth of the first frequency band and/or the third frequency band may also be adjusted by adjusting the frequency selection circuit 60, for example the second filter circuit 63.

A third identified point (1.5908, -6.3951) is on curve B. The third identification point (1.5908, -6.3951) may be a frequency band supported by the second resonant mode. It can be seen that the antenna assembly 100 has good antenna performance at around 1.6GHz, i.e. the antenna assembly 100 has good antenna performance at around the second frequency band. Furthermore, the antenna assembly 100 has a good working state, and can meet engineering requirements.

A second identified point (2.3102, -12.663) is on curve C. It can be seen that the first feed 10 and the second feed 20 have a better isolation around 2.4GHz, i.e. around the first frequency band. Also, there is a better isolation around the third marker point, i.e. around the second frequency band.

Referring to fig. 10, fig. 10 is a graph comparing the overall system efficiency (System Total Efficiency) curves of the antenna assembly 100 of fig. 7 and the antenna assembly 100 of fig. 8 in some embodiments, with the horizontal axis being frequency (GHz) and the vertical axis being the overall system efficiency (dB). Curve D is a graph of the overall system efficiency of the antenna assembly 100 of fig. 8 in some embodiments, and curve E is a graph of the overall system efficiency of the antenna assembly 100 of fig. 7 in some embodiments. The curve E has a first (2.4522, -2.5128) and a second (2.3016, -3.1844) identification point, and the curve D has a third (2.3997, -4.2778) identification point. It can be seen that the system efficiency of curve E is wider, higher, and bandwidth is wider, with greater tolerance capability than the system efficiency of curve D.

Next, an electronic device to which the antenna assembly 100 of the above-described embodiment can be mounted will be described. The electronic device may be any of a number of electronic devices including, but not limited to, cellular telephones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, calculators, programmable remote controls, pagers, netbooks, personal Digital Assistants (PDAs), portable Multimedia Players (PMPs), moving picture experts group (MPEG-1 or MPEG-2), audio layer 3 (MP 3) players, portable medical devices, and digital cameras, combinations thereof, and the like.

In some embodiments, the electronic device may include, but is not limited to, an electronic device with communication functions such as a mobile phone, an internet device (MID), an electronic book, a portable play station (Play Station Portable, PSP), or a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA).

Referring to fig. 11 and fig. 12 together, fig. 11 is a schematic view of an overall structure of a folded state of an electronic device according to some embodiments of the application, and fig. 12 is a schematic view of an unfolded state of the electronic device shown in fig. 11. The electronic device 300 may include a first housing 301 in which the antenna assembly 100, e.g., the first radiator 10, a second housing 302 in which the antenna assembly 100, e.g., the second radiator 20, is disposed and which slides relative to the first housing 301, and a flexible display screen 303 disposed on the first housing 301 and the second housing 302.

The first housing 301 is slidable relative to the second housing 302, and can partially slide into the second housing 302 to achieve folding, and is in a folded state. The first housing 301 is slidable relative to the second housing 302 and partially slidable out of the second housing 302 to effect deployment in a deployed state.

The first housing 301 and the second housing 302 may be used to carry and mount electronic components such as a circuit board (on which a control unit such as a processor is disposed), a battery, a camera, and a sensor. The flexible display 303 has a bendable property and can be used for being electrically connected with electronic components such as a control unit, a battery and the like of a circuit board so as to display information such as image information and text information. The flexible display 303 may partially slide into the first housing 301 or out of the first housing 301 when the first housing 301 and the second housing 302 slide relative to each other. The antenna assembly 100, e.g., the first radiator 10, the second radiator 20, may be electrically connected with a circuit board, e.g., a control unit, a battery, etc., to achieve antenna performance. The relative positions of the first radiator 10 and the second radiator 20 can be adjusted by sliding the first housing 301 and the second housing 302 relative to each other. Further, different antenna performances of the antenna assembly 100 are realized, the antenna assembly 100 is kept to work in an optimal state all the time, and the overall communication capacity of the electronic device 300 is improved.

It will be appreciated that the first housing 301 may be slidable relative to the second housing 302, and that the distance between the first and second radiators 10, 20 may be adjusted such that the first and second radiators 10, 20 are in the capacitively coupled or non-capacitively coupled state in the above embodiments. For example, the first radiator 10 and the second radiator 20 are in a capacitively coupled state in the collapsed state, and the first radiator 10 and the second radiator 20 are in a non-capacitively coupled state in the expanded state. For example, the first radiator 10 and the second radiator 20 are in a non-capacitively coupled state in the collapsed state, and the first radiator 10 and the second radiator 20 are in a capacitively coupled state in the expanded state.

In addition, the first housing 301 and the second housing 302 may cooperate to form the adjustment assembly 200 to adjust the distance between the first radiator 10 and the second radiator 20. Of course, in some embodiments, the adjusting assembly 200 may not be limited to the first housing 301 and the second housing 302, but may include other structures. Of course, in some embodiments, the adjusting assembly 200 may not include the first housing 301 and the second housing 302, but may have other structures, as long as the structures capable of changing the positions of the first radiator 10 and the second radiator 20 can be configured according to technical schemes known to those skilled in the art, and will not be described herein. That is, the structure of the adjustment of the stub length L1 of the first radiator 10 and the second radiator 20 coupled to each other in fig. 4 may be provided in a manner known to those skilled in the art. That is, the structure capable of adjusting the distance L2 between the first radiator 10 and the second radiator 20 in fig. 6 may be provided in a technical scheme known to those skilled in the art, that is, the structure capable of adjusting the rotation of the first radiator 10 and the second radiator 20 about the folding line M in fig. 8 may be provided in a technical scheme known to those skilled in the art. In some scenarios, the first radiator 10 and/or the second radiator 20 are provided on the adjustment assembly 200. In some scenarios, the first radiator 10 and/or the second radiator 20 are connected with the adjustment assembly 200.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Referring to fig. 12, the first housing 301 may include a first ground plane 3011 and a first frame 3012 surrounding an edge of the first ground plane 3011. Wherein the first ground plane 3011 is used to carry the flexible display screen 303. The first ground plane 3011 cooperates with the first frame 3012 to form a set accommodating space for accommodating the flexible display screen 303. The flexible display 303 can be folded into the receiving space for storage. When the first housing 301 and the second housing 302 slide relatively, the flexible display 303 is partially slid and folded into the first housing 301.

The first ground plane 3011 may serve as a ground for electrical connection to the first ground point 13 in the antenna assembly 100 of the above-described embodiment. At least a portion of the edge of the first ground plane 3011 may be fixedly connected to the first frame 3012. Further, in some scenarios, a first gap 3013 is formed between the first ground plane 3011 and the first frame 3012.

The first radiator 10 in the above embodiment is provided on the first frame 3012. In some embodiments, a first gap 3013 is formed between the first radiator 10 and the first ground plane 3011 and is electrically connected to the first ground plane 3011 at the first ground point 13.

In some embodiments, the first frame 3012 is at least partially made of conductive metal, and further, may partially function as the first radiator 10.

The second housing 302 is slidable relative to the first housing 301. In some embodiments, the second housing 302 may be slidably coupled to the first housing 301. Specifically, the sliding connection can be realized by a slideway, a roller, a sliding block and the like.

Referring to fig. 12, the second housing 302 includes a second ground plane 3021 and a second frame 3022 surrounding an edge of the second ground plane 3021. Wherein the second ground plane 3021 cooperates with the first housing 301, e.g., the first ground plane 3011, to collectively carry the flexible display screen 303. The second ground plane 3021 and the second frame 3022 cooperate to form a accommodating space for accommodating the flexible display 303 and the first housing 301. The receiving space may house a portion of the flexible display 303. When the first housing 301 and the second housing 302 slide relatively, the flexible display 303 is partially slid and bent into the accommodating space, so that the first housing 301 slides into the accommodating space or slides out of the accommodating space. At the same time, the flexible display 303 can also slide and bend into the accommodating space.

The second ground plane 3021 may serve as a ground for electrical connection with the second ground point 23 in the antenna assembly 100 of the above-described embodiment. At least a portion of the edge of the second ground plane 3021 may be fixedly connected to the second frame 3022. Further, in some scenarios, a second gap 3023 is formed between the second ground plane 3021 and the second bezel 3022.

The second radiator 20 in the above embodiment is disposed on the second frame 3022. In some embodiments, a second gap 3023 is formed between the second radiator 20 and the second ground plane 3021 and is electrically connected to the second ground plane 3021 at the second ground point 23.

In some embodiments, the second bezel 3022 is at least partially made of conductive metal and, in turn, may be partially used as the second radiator 20.

Referring to fig. 12, 13 and 14, fig. 13 is a state diagram of the first housing 301 and the second housing 302 in fig. 12 when they slide relatively in one embodiment, and fig. 14 is a state diagram of the first housing 301 and the second housing 302 in fig. 12 when they slide relatively in one embodiment. The first ground plane 3011 and the first frame 3012 of the first housing 301 are inserted into the accommodating space of the second housing 302 at one side, so that the first housing 301 and the second housing 302 slide. The first housing 301 can slide in and out from the accommodating space of the second housing 302.

In an embodiment, the first housing 301 slides out of the accommodating space of the second housing 302 relative to the second housing 302 to be in an unfolded state, so that the first radiator 10 and the second radiator 20 are separated from the capacitive coupling state, and are in a non-capacitive coupling state, so that the first radiator 10 and the second radiator 20 in the antenna assembly 100 can operate according to the resonant modes of the antenna assembly 100 shown in fig. 5, such as the first resonant mode and the second resonant mode.

In an embodiment, the first housing 301 slides into the accommodating space of the second housing 302 relative to the second housing 302 to be in a folded state, so that the first radiator 10 and the second radiator 20 are in a capacitive coupling state, so that the first radiator 10 and the second radiator 20 in the antenna assembly 100 can operate according to the resonant modes of the antenna assembly 100 shown in fig. 1, such as the first resonant mode, the second resonant mode, and the third resonant mode.

In some embodiments, when the first housing 301 and the second housing 302 are in the retracted state, the front projection of the first slit 101 on the second housing 302 at least partially overlaps, or may overlap, the second slit 102.

Referring to fig. 12 and 15, fig. 15 is a schematic cross-sectional view of the electronic device 300 shown in fig. 12. The flexible display 303 has a display surface and a non-display surface to display information on the display surface side, and is provided on the first housing 301 and the second housing 302 on the non-display surface side.

The flexible display 303 may be folded toward the non-display surface side to fold the flexible display 303, and a first folded portion 3031 and a second folded portion 3032 opposite to the first folded portion 3031 and connected to each other may be formed. The surface of the first half portion 3031 remote from the second half portion 3032 is a display surface. The surface of the second half portion 3032 remote from the first half portion 3031 is a display surface. The first half-over portion 3031 may be disposed on the first ground plane 3011 and the second ground plane 3021. The second half-folded portion 3032 may be disposed in the accommodating space, or the accommodating space and the accommodating space, and when the first case 301 and the second case 302 are relatively slid, the second half-folded portion 3032 may slide out of the accommodating space to become a part of the first half-folded portion 3031, and the first half-folded portion 3031 may slide into the accommodating space to become a part of the second half-folded portion 3032. In some scenarios, as the first housing 301 and the second housing 302 slide relative to each other, the second folded portion 3032 of the flexible display 303 will gradually slide out of the receiving space to increase the display area of the first folded portion 3031. When the first housing 301 and the second housing 302 slide relatively, the first folded portion 3031 of the flexible display 303 will extend into the accommodating space, so as to reduce the display area of the first folded portion 3031.

It will be appreciated that the first radiator 10 and the second radiator 20 may be disposed on the first housing 301 and the second housing 302 not only in the arrangement shown in fig. 11, but also in the fitting relationship of the first radiator 10 and the second radiator 20 in the above-described embodiment.

Referring to fig. 16, fig. 16 is a schematic structural diagram of the electronic device 100 shown in fig. 11 in other embodiments. The second radiator 20 may be as shown in fig. 7, and the second radiator 20 may include a third portion 201 and a fourth portion 202 connected by bending. The third portion 201 may have a second free end 21 and the fourth portion 202 may have a second end 24. The third portion 201 is connected to the fourth portion 202, and the point of intersection is the second intersection 203. The second feeding point 22 is located at the third section 201. The second ground point 23 is located at the fourth portion 302.

In some embodiments, the first housing 301 slides out of the accommodating space of the second housing 302 relative to the second housing 302 to be in an unfolded state, so that the first radiator 10 and the second radiator 20, for example, the third portion 201, are separated from the capacitive coupling state, and are in a non-capacitive coupling state, so that the first radiator 10 and the second radiator 20 in the antenna assembly 100 operate according to the resonant modes of the antenna assembly 100 shown in fig. 5, for example, the first resonant mode and the second resonant mode.

In an embodiment, the first housing 301 slides into the accommodating space of the second housing 302 relative to the second housing 302 to be in a folded state, so that the first radiator 10 and the second radiator 20, for example, the third portion 201, are in a capacitive coupling state, so that the first radiator 10 and the second radiator 20 in the antenna assembly 100 operate according to the resonant modes, for example, the first resonant mode, the second resonant mode and the third resonant mode, of the antenna assembly 100 shown in fig. 1.

In some embodiments, the first radiator 10 may also be designed as shown in fig. 7, and further, the first radiator 10 and the second radiator 20 may be matched as shown in fig. 7.

It will be appreciated that the connection relationship of the first housing 301 and the second housing 302 is not limited to a sliding connection. It may also be other means of connection. The first housing 301 and the second housing 302 are foldable to be in a folded state or an unfolded state. For example, referring to fig. 16 and 17, fig. 17 is an exploded view of the electronic device of fig. 16. The electronic device 600 may include first and second housings 601 and 602 for mounting the antenna assembly 100, a folder 603 connecting the first and second housings 601 and 602, and a flexible display screen 604 disposed on the first and second housings 601 and 602 and the folder 603. The folding portion 603 connects the first housing 601 and the second housing 602, and the folding portion 603 may have a folding line M in the above embodiment. The folding portion 603 is used to fold the electronic device 600 such that the first casing 601 and the second casing 602 are stacked and folded, and in a folded state, or such that the first casing 601 and the second casing 602 are positioned on both sides of the folding portion and unfolded, and in an unfolded state. That is, the first housing 601 and the second housing 602 are configured to be foldable so that the first housing 601 and the second housing 602 can be relatively unfolded, in an unfolded state, or folded, in a folded state.

The first housing 601 and the second housing 602 may be used to carry and mount electronic components such as a circuit board (a device such as a processor is disposed on the circuit board), a battery, a camera, and a sensor. The flexible display 303 has a bendable property and can be used for being electrically connected with electronic components such as a control unit, a battery and the like of a circuit board so as to display information such as image information and text information. The flexible display 604 is folded or unfolded when the first housing 601 and the second housing 602 are relatively folded. The antenna assembly 100, e.g., the first radiator 10, the second radiator 20, may be electrically connected with a circuit board, e.g., a control unit, a battery, etc., to achieve antenna performance. The relative positions of the first radiator 10 and the second radiator 20 can be adjusted by rotating the first housing 601 and the second housing 602 about the fold line M. Further, different antenna performances of the antenna assembly 100 are realized, the antenna assembly 100 is kept to work in an optimal state all the time, and the overall communication capacity of the electronic device 600 is improved.

It will be appreciated that the first housing 601 is rotatably foldable about the fold line M relative to the second housing 602, and that the distance between the first radiator 10 and the second radiator 20 can be adjusted such that the first radiator 10 and the second radiator 20 are in the capacitively coupled state or the non-capacitively coupled state in the above embodiment. For example, the first radiator 10 and the second radiator 20 are in a capacitively coupled state in the collapsed state, and the first radiator 10 and the second radiator 20 are in a non-capacitively coupled state in the expanded state. For example, the first radiator 10 and the second radiator 20 are in a non-capacitively coupled state in the collapsed state, and the first radiator 10 and the second radiator 20 are in a capacitively coupled state in the expanded state.

In addition, the first housing 601 and the second housing 602 may cooperate to form the adjustment assembly 200 to adjust the distance between the first radiator 10 and the second radiator 20. Of course, in some embodiments, the adjusting assembly 200 may not be limited to the first housing 601 and the second housing 602, but may include other structures.
