For example, a "first radiator" may be converted to a "second radiator" and, correspondingly, a "second radiator" may be converted to a "first radiator".

It will be appreciated that the first radiator 10 may be used alone. Of course, the first radiator 10 can be used in conjunction with the second radiator 20. In the antenna assembly 100, the usage modes and the frequency band information of the first radiator 10 and the second radiator 20 can be specifically set according to the actual requirements.

Of course, in some embodiments, tuning of multiple mid-high frequency bands of the second radiator 20 may also be implemented. Thus, the tuning control circuit, for example the first tuning control circuit, the second tuning control circuit, may be comprised of a switch control circuit and/or a load circuit, or of an adjustable capacitor and/or an adjustable inductor. In an embodiment, the switch control circuit may be a switch chip with a switch function, or may be a single pole multiple throw switch or a single pole single throw switch.

In some embodiments, the orthographic projection of the third end 21 onto the first radiator 10 is located outside the first radiator 10. For example, the orthographic projection of the third end 21 onto the first radiator 10 is located on a side of the first end 11 remote from the second end 12. In some embodiments, the orthographic projection of the third end 21 onto the first radiator 10 is located on the first radiator 10. For example, the orthographic projection of the third end 21 onto the first radiator 10 is located between the first end 11 and the second end 12. In some embodiments, the orthographic projection of the third end 21 onto the first radiator 10 coincides with the first end 11.

It will be appreciated that in some embodiments, the orthographic projection of the first end 11 onto the second radiator 20 is located outside the second radiator 20. For example, the orthographic projection of the first end 11 onto the second radiator 20 is located on a side of the third end 21 remote from the fourth end 22. In some embodiments, the orthographic projection of the first end 11 onto the second radiator 20 is located on the second radiator 20.

For example, the orthographic projection of the fourth end 22 onto the first radiator 10 is located on the side of the second end 12 remote from the first end 11. In some embodiments, the orthographic projection of the fourth end 22 onto the first radiator 10 is located on the first radiator 10. For example, the orthographic projection of the fourth end 22 onto the first radiator 10 is located between the second end 12 and the first end 11. In some embodiments, the orthographic projection of the fourth end 22 onto the first radiator 10 coincides with the second end 12.

It will be appreciated that in some embodiments, the orthographic projection of the second end 12 onto the second radiator 20 is located outside the second radiator 20. For example, the orthographic projection of the second end 12 onto the second radiator 20 is located on a side of the fourth end 22 remote from the third end 21. In some embodiments, the orthographic projection of the second end 12 onto the second radiator 20 is located on the second radiator 20. For example, the orthographic projection of the second end 12 onto the second radiator 20 is located between the third end 21 and the fourth end 22.

In some embodiments, the second radiator 20 may be grounded at the third end 21 and/or the fourth end 22. In some embodiments, the "third end" and the "fourth end" may also be referred to as "ground points". Of course, the "third end" may also be referred to as a "third ground point" and the "second end" may also be referred to as a "fourth ground point".

The tuning control circuits, such as the third tuning control circuit and the fourth tuning control circuit, are mainly used to realize the requirement that the second radiator 20 supports the low frequency band and/or the middle-high frequency band. Thus, the tuning control circuit, for example the third tuning control circuit, the fourth tuning control circuit, may be composed of a switch control circuit and/or a load circuit, or of an adjustable capacitor and/or an adjustable inductor. In an embodiment, the switch control circuit may be a switch chip with a switch function, or may be a single pole multiple throw switch or a single pole single throw switch.

The second radiator 20 is provided with a ground point, e.g. a fifth ground point 23, between the third 21 and fourth 22 ends, which ground point, e.g. fifth ground point 23, may be electrically connected to a matching circuit, e.g. a second matching circuit 24. The matching circuit, for example the second matching circuit 24, is grounded. In some embodiments, a ground point, such as fifth ground point 23, may be directly grounded, and in some embodiments, a ground point, such as fifth ground point 23, may be omitted.

It will be appreciated that in other embodiments, the designations "first ground point", "second ground point", "third ground point", "fourth ground point" and "ground point" in the above embodiments may be switched to each other.

In addition, in other embodiments, the names "first tuning control circuit", "second tuning control circuit", "third tuning control circuit", "fourth tuning control circuit", and "tuning control circuit" in the above embodiments may be switched to each other. For example, "the second tuning control circuit" may be converted into "the first tuning control circuit", and accordingly, "the first tuning control circuit" may be converted into "the second tuning control circuit".

In addition, in other embodiments, the names "first matching circuit", "second matching circuit", and "matching circuit" in the above embodiments may be mutually converted. For example, the "second matching circuit" may be converted into the "first matching circuit", and accordingly, the "first matching circuit" may be converted into the "second matching circuit".

Referring to fig. 1 and fig. 2 together, fig. 2 is a schematic structural diagram of the antenna assembly 100 shown in fig. 1 in another embodiment. In fig. 1, the length of the branch of the mutual coupling of the first radiator 10 and the second radiator 20 is a. When the first radiator 10 and the second radiator 20 slide relatively, for example, slide toward the side of the first end 11 away from the second end 12, the state in fig. 2 can be slid to adjust the stub length a. For example, the stub length a in fig. 2 is shorter than the stub length a in fig. 1.

When the branch length a is changed, the antenna performance of the antenna assembly 100 may be changed, for example, in fig. 1, the operating frequency band of the antenna assembly 100 is the target frequency band, and in fig. 2, the operating frequency band of the antenna assembly 100 may deviate from the target frequency band due to the change of the branch length a.

In still further embodiments, the matching circuits, e.g., the first matching circuit 14, the second matching circuit 24, may be adjusted according to the stub length a so that the antenna performance of the antenna assembly 100 is optimal. In still further embodiments, tuning control circuits such as a first tuning control circuit, a second tuning control circuit, a third tuning control circuit, and a fourth tuning control circuit may be adjusted according to the stub length a to optimize the antenna performance of the antenna assembly 100. For example, in fig. 1, the operating frequency band of the antenna assembly 100 is a target frequency band, and in fig. 2, the operating frequency band of the antenna assembly 100 deviates from the target frequency band due to the variation of the branch length a, and the tuning control circuits, such as the first tuning control circuit, the second tuning control circuit, the third tuning control circuit, and the fourth tuning control circuit, may be adjusted according to the branch length a so that the operating frequency band of the antenna assembly 100 is the target frequency band at this time.

It will be appreciated that when the first radiator 10 and the second radiator 20 slide relatively, they can slide to the position shown in fig. 1 or fig. 2, so that the first radiator 10 and the second radiator 20 can be in a distributed capacitive coupling state to form a distributed capacitive coupling structure. And adjusts the stub length a while the first radiator 10 and the second radiator 20 are slid relatively.

In some embodiments, referring to fig. 3, fig. 3 is a schematic diagram illustrating a structure of the antenna assembly 100 shown in fig. 1 in another embodiment. When the first radiator 10 and the second radiator 20 slide relatively, the first radiator 10 and the second radiator 20 can also slide to be separated from the distributed capacitive coupling state, so that the first radiator 10 works independently. That is, when the first radiator 10 and the second radiator 20 slide relatively, the stub length a may be made 0. However, the stub length a is 0, which does not mean that the first radiator 10 and the second radiator 20 have been out of the distributed capacitive coupling state.

The antenna assembly 100 in the embodiment of fig. 1 is subjected to corresponding antenna performance testing using simulation software. One embodiment can be seen in fig. 4 and 5, where fig. 4 is a return loss curve of the antenna assembly 100 of fig. 1 when only the first radiator 10 is operating in one embodiment. Fig. 5 is a graph of return loss curves of the antenna assembly 100 of fig. 1 when the first radiator 10 and the second radiator 20 are operated in an embodiment. When the first radiator 10 and the second radiator 20 slide relatively, the branch length a changes to 0 until the first radiator 10 and the second radiator 20 are separated from the distributed capacitive coupling state, and only the first radiator 10 in the antenna assembly 100 works to obtain the return loss curve shown in fig. 4. When the first radiator 10 and the second radiator 20 slide relatively, the first radiator 10 and the second radiator 20 have a mutually coupled branch length a, and the first radiator 10 and the second radiator 20 form a distributed capacitive coupling structure shown in fig. 1 due to the change of the branch length a to the maximum value, so that the first radiator 10 and the second radiator 20 in the antenna assembly 100 work together to obtain a return loss curve shown in fig. 5.

The return loss in fig. 4 corresponding to a frequency of 1.795GHz in the mid-high band is-9.2 dB. The return loss in fig. 5, corresponding to a frequency of 1.75GHz in the mid-high band, is-5.1 dB. The return loss in fig. 5 corresponding to a frequency of 1.93GHz in the mid-high band is-12 dB. It can be seen that the distributed capacitive coupling structure formed by the first radiator 10 and the second radiator 20 in the antenna assembly 100 enables the antenna assembly 100 to support a plurality of middle-high frequency bands, so as to expand the bandwidth of the middle-high frequency bands and improve the antenna performance of the antenna assembly 100.

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.

Referring to fig. 6 and fig. 7 together, fig. 6 is a schematic overall structure diagram of a fully closed state of an embodiment of the electronic device according to the present application, and fig. 7 is a schematic split structure diagram of the electronic device in the embodiment of fig. 6. The electronic device 200 may include a first housing 30 in which the antenna assembly 100, e.g., the second radiator 20, a second housing 40 in which the antenna assembly 100, e.g., the first radiator 10, is disposed and which slides relative to the first housing 30, and a flexible display screen 50 disposed on the first housing 30 and the second housing 40. The second housing 40 may slide relative to the first housing 30, and may partially slide into the first housing 30 to achieve folding, or may partially slide out of the first housing 30 to achieve unfolding. The first housing 30 and the second housing 40 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 50 has a bendable property and can be used for being electrically connected with electronic components such as a circuit board (a device such as a processor is arranged on the circuit board), a battery and the like to display information such as image information and text information. The flexible display 50 may be partially slid into the second housing 40 or out of the second housing 40 when the first housing 30 and the second housing 40 are slid relative to each other. The antenna assembly 100, for example, the first radiator 10, the second radiator 20, may be electrically connected with a circuit board (a device on which a control unit such as a processor is provided), a battery, or the like to achieve antenna performance. The stub length a of the first radiator 10 and the second radiator 20 coupled to each other may be adjusted to be smaller or larger in response to the relative sliding of the first housing 30 and the second housing 40. 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 equipment 200 is improved.

It will be appreciated that the designations of "first housing," second housing, "and" housing "may be interchanged, such as in some embodiments," first housing "may also be referred to as" second housing, "and" second housing "may also be referred to as" first housing.

The first housing 30 includes a bottom wall 31, side walls (e.g., a first side wall 32, a second side wall 33, and a third side wall 34) surrounding the bottom wall 31, and a top wall 35 disposed opposite to the bottom wall 31 and fixedly connected to the side walls. Wherein, a receiving space 301 is formed between the bottom wall 31 and the top wall 35 for receiving the second housing 40 and a portion of the flexible display 50. The side of the top wall 35 remote from the bottom wall 31 is used to lay down the flexible display 50 to support the flexible display 50.

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.

In addition, the names of the first side wall, the second side wall, the side wall and the like can be mutually converted, for example, in some embodiments, the first side wall can be also called as the second side wall, and the second side wall can be also called as the first side wall.

The side walls are fixedly connected to the edges of the bottom wall 31 and extend to one side of the top wall 35 to be fixedly connected to the top wall 35. The side walls may include first and second side walls 32 and 33 disposed opposite each other, and a third side wall 34 connected and fixed to the first and second side walls 32 and 33. The first side wall 32, the second side wall 33, and the third side wall 34 are fixedly connected to the top wall 35.

In some embodiments, to enable the first housing 30 and the second housing 40 to slide relatively, the side walls, such as the first side wall 32 and the second side wall 33, are provided with the first sliding portion 321 at a position in the accommodating space 301 to slide relatively to the second housing 40. In some embodiments, the first sliding portion 321 is a slideway, a roller, a slider, or the like. In one embodiment, the sliding direction of the first sliding portion 321 coincides with the extending direction of the first sidewall 32. In some embodiments, the first sliding portion 321 may also be disposed at other positions on the first housing 30, which will not be described in detail.

In some embodiments, the second radiator 20 is disposed on a sidewall, such as the second sidewall 33. In some embodiments, the second radiator 20 may be disposed in an extending direction of a sidewall, such as the second sidewall 33, and it is understood that the second radiator 20 is disposed to extend to one side of the third sidewall 34 to be disposed on the third sidewall 34.

In some embodiments, a sidewall, such as the first sidewall 32, is provided with a first position detecting member 322 for cooperating with the second housing 40 to detect the relative position of the first housing 30 and the second housing 40. In some embodiments, the first position detecting member 322 may be a proximity sensor, a hall sensor, a magnetic member, or the like. In some embodiments, the first position detecting member 322 is disposed adjacent to the first sliding portion 321. In some embodiments, when the first position detecting member 322 is a magnetic member, the first position detecting member 322 is preferably disposed on the first side wall 32 to reduce the influence of the first position detecting member 322 on the antenna performance of the second radiator 20. It can be appreciated that the first position detecting member 322 may be disposed at other positions as needed, which will not be described in detail.

The top wall 35 may include a plurality of side-by-side strip support walls 351. A first caulking 302 is provided between two adjacent strip-shaped supporting walls 351 to give way to the second casing 40. In some embodiments, the first caulking 302 communicates with the accommodating space 301, so as to further reduce the thickness of the electronic device 200.

Referring to fig. 7 and 8, fig. 8 is an exploded view of the second housing 40 in fig. 7. The second housing 40 includes a bottom plate 41, side plates (e.g., a first side plate 42, a second side plate 43, and a third side plate 44) surrounding the edge of the bottom plate 41, a top plate 45 opposite to the bottom plate 41 and fixedly connected to the side plates, and rollers 46 disposed on the side plates. Wherein an accommodating space 401 is provided between the bottom plate 41 and the top plate 45 for accommodating the flexible display screen 50.

It will be appreciated that the designations "first slider", "second slider", and "slider" may be interchanged, for example, in some embodiments, the "first slider" may also be referred to as "second slider" and the "second slider" may also be referred to as "first slider".

In some embodiments, the first radiator 10 is disposed on a side plate, such as the second side plate 43. In some embodiments, the first radiator 10 may be disposed in an extending direction of a side plate, such as the second side plate 43, and it is understood that the first radiator 10 is disposed to extend to one side of the third side plate 44 to be disposed on the third side plate 44.

In some embodiments, a side plate, such as the first side plate 42, is provided with a second position detecting member 422 for cooperating with the first housing 30, such as the first position detecting member 322, and the first position detecting member 322 and/or the second position detecting member 422 are electrically connected with an electronic component, such as a circuit board (a control unit, such as a processor, etc., is provided on the circuit board), a battery, etc., to detect the relative positions of the first housing 30 and the second housing 40. The circuit board (on which a control unit such as a processor or the like is provided) receives the detection information detected by the first position detecting member 322 and the second position detecting member 422 in cooperation. In some embodiments, the second position detecting member 422 may be a proximity sensor, a hall sensor, a magnetic member, or the like.

In addition, the detection unit may be provided in the first housing 30 and/or the second housing 40, depending on the configuration.

It will be appreciated that the designations "first position sensing element", "second position sensing element", and "position sensing element" may be interchanged, for example, in some embodiments, the "first position sensing element" may also be referred to as "second position sensing element" and the "second position sensing element" may also be referred to as "first position sensing element".

The top plate 45 is spaced from the third side plate 44 such that a roller 46 is mounted between the top plate 45 and the third side plate 44. The top plate 45 may include a plurality of strip support plates 451 disposed side by side. A second caulking 402 is provided between two adjacent strip support plates 451 to give way to the first housing 30, for example, the strip support wall 351. In some embodiments, the second caulking 402 communicates with the accommodating space 301, so as to further reduce the thickness of the electronic device 200.

It will be appreciated that the designations "first caulking", "second caulking", and "caulking" may be interchanged, for example, in some embodiments, the "first caulking" may also be referred to as "second caulking" and the "second caulking" may also be referred to as "first caulking".

In an embodiment, the width of the second caulking groove 402 is the same as the width of the strip-shaped supporting wall 351, or the width of the second caulking groove 402 is larger than the width of the strip-shaped supporting wall 351, so that the strip-shaped supporting wall 351 slides in the extending direction of the second caulking groove 402 when the first casing 30 and the second casing 40 slide relatively.

In an embodiment, the width of the strip support plate 451 is the same as the width of the first caulking groove 302, or the width of the strip support plate 451 is smaller than the width of the first caulking groove 302, so that the strip support plate 451 slides in the extending direction of the first caulking groove 302 when the first housing 30 and the second housing 40 slide relatively.

The roller 46 is located between the top plate 45 and the third side plate 44, and is rotatably connected to the first side plate 42 and the second side plate 43. In one embodiment, the axial direction of the roller 46 is perpendicular to the sliding direction of the first housing 30 and the second housing 40.

Referring to fig. 7, 9 and 10, fig. 9 is a state diagram of the first housing 30 and the second housing 40 in fig. 7 when they slide relatively in one embodiment, and fig. 10 is a state diagram of the first housing 30 and the second housing 40 in fig. 7 when they slide relatively in one embodiment, wherein the bottom plate 41, the first side plate 42, the second side plate 43 and the top plate 45 of the second housing 40 are inserted into the accommodating space 301 on a side far from the third side plate 44, and on a side far from the third side wall 34, of the bottom wall 31 of the first housing 30, so that the first sliding portion 321 and the second sliding portion 421 are mounted together, and the first housing 30 and the second housing 40 slide through the first sliding portion 321 and the second sliding portion 421. The strip-shaped supporting wall 351 is located in the second caulking groove 402, the strip-shaped supporting plate 451 is located in the first caulking groove 302, and when the first casing 30 and the second casing 40 slide relatively, the strip-shaped supporting wall 351 slides in the extending direction of the second caulking groove 402, and the strip-shaped supporting plate 451 slides in the extending direction of the first caulking groove 302.

That is, the second housing 40 is movable toward a side closer to the third side wall 34 or toward a side farther from the third side wall 34 with respect to the first housing 30.

When the first casing 30 and the second casing 40 slide relatively, the first radiator 10 and the second radiator 20 slide relatively, the first position detecting member 322 and the second position detecting member 422 cooperate, and the position of the first casing 30 and the second casing 40 sliding relatively is detected by a circuit board (a control unit such as a processor or the like is provided on the circuit board), so that the branch length a can be indirectly detected. The circuit board (on which a control unit such as a processor or the like is disposed) may adjust the matching circuits such as the first matching circuit 14 and the second matching circuit 24 through the stub length a so that the antenna performance of the antenna assembly 100 is in an optimal state. In still further embodiments, the tuning control circuit, such as the first tuning control circuit, the second tuning control circuit, the third tuning control circuit, and the fourth tuning control circuit, may be adjusted according to the branch length a to make the antenna performance of the antenna assembly 100 in an optimal state, so that the operating frequency band of the antenna assembly 100 is the target frequency band.

In an embodiment, the second housing 40 is movable relative to the first housing 30 to a side away from the third sidewall 34 to disengage the first radiator 10 from the second radiator 20 in a distributed capacitive coupling state, so that the first radiator 10 in the antenna assembly 100 operates. For example, when the first and second housings 30 and 40 are fully unfolded, the first and second radiators 10 and 20 are out of the distributed capacitive coupling state. Of course, in some embodiments, the first radiator 10 and the second radiator 20 may be in a distributed capacitive coupling state when the first housing 30 and the second housing 40 are fully deployed.

In an embodiment, the second housing 40 is movable to a side close to the third sidewall 34 relative to the first housing 30, so that the first radiator 10 and the second radiator 20 are in a distributed capacitive coupling state, so that the first radiator 10 and the second radiator 20 in the antenna assembly 100 operate simultaneously. That is, when the first housing 30 and the second housing 40 are completely retracted, the first radiator 10 and the second radiator 20 are in a distributed capacitive coupling state.

In addition, the second housing 40 can move to a side close to the third side wall 34 relative to the first housing 30, so that the antenna performance of the first radiator 10 is reduced due to the influence of the first housing 30 and the electronic components therein, and at this time, the distributed capacitive coupling structure of the first radiator 10 and the second radiator 20 expands the broadband of medium-high frequency and improves the antenna performance, and further, the matching circuits such as the first matching circuit 14 and the second matching circuit 24 are adjusted, so that the antenna performance of the antenna assembly 100 is in an optimal state. In still further embodiments, tuning control circuits such as a first tuning control circuit, a second tuning control circuit, a third tuning control circuit, and a fourth tuning control circuit may be adjusted according to the stub length a to optimize the antenna performance of the antenna assembly 100, so as to reduce the influence of the first housing 30 and the internal electronic components thereof on the first radiator 10.

Referring to fig. 7 and 11, fig. 11 is a schematic cross-sectional view of the electronic device 200 shown in fig. 7. The flexible display 50 has a display surface and a non-display surface to display information on the display surface side, and is provided on the first housing 30 and the second housing 40 on the non-display surface side. The flexible display 50 may be folded toward the non-display surface side to fold the flexible display 50, and may form a first folded portion 51, a second folded portion 52 opposite to the first folded portion 51, and a folded portion 53 connecting the first and second folded portions 51 and 52. The surface of the first folded portion 51 away from the second folded portion 52 is a display surface. The surface of the second folded portion 52 away from the first folded portion 51 is a display surface. The first folding portion 51 may be disposed on a surface of the first housing 30, for example, a side of the top wall 35 away from the bottom wall 31, the folding portion 53 may be mounted on the roller 46, and the second folding portion 52 may be disposed in the accommodating space 401. The side of the bending portion 53 away from the roller 46 is a display surface.

When the first casing 30 and the second casing 40 slide relatively, the second folded portion 52 of the flexible display 50 gradually slides out of the accommodating space 401, so as to increase the display area of the first folded portion 51. When the first housing 30 and the second housing 40 slide relatively, the first folded portion 51 of the flexible display 50 will extend into the secondary accommodating space 401, so as to reduce the display area of the first folded portion 51.

It will be appreciated that the connection between the first housing 30 and the second housing 40 is not limited to a sliding connection. It may also be other means of connection. For example, referring to fig. 12, fig. 12 is a schematic structural diagram of the electronic device 200 in another embodiment in the embodiment shown in fig. 6. The electronic device 200 may include a housing assembly for mounting the antenna assembly 100 and a display screen 50 disposed on the housing assembly. The housing assembly may include a first housing 30, a second housing 40, and a fold 60 connecting the first housing 30 and the second housing 40. The housing in the housing assembly may not be limited to the first housing 30 and the second housing 40, may include a third housing, may include a fourth housing, may include a fifth housing, and the like. In addition, the number of the folded portions 60 in the housing assembly may be plural, so that two housings, such as the first housing 30 and the second housing 40, which are connected, for example, the third housing and the fourth housing, may each be connected by one folded portion 60 to form the housing assembly. The folding portion 60 allows the two connected housings, such as the first housing 30 and the second housing 40, to be folded to achieve folding, and the folding portion 60 allows the two connected housings, such as the first housing 30 and the second housing 40, to be unfolded to support the display screen 50. When two housings, such as the first housing 30 and the second housing 40, are folded, the electronic apparatus 200 can be folded and housed. The first housing 30 and the second housing 40 are fixedly connected through the folding portion 60, so that the first housing 30 and the second housing 40 can be folded in half by folding of the folding portion 60. The above embodiments can be referred to for the second radiator 20 in which the first radiator 10 and the second radiator 40 are provided for the first housing 30.

The first radiator 10 and the second radiator 20 may change positions when the first housing 30 and the second housing 40 are folded or unfolded, so as to affect the antenna performance of the antenna assembly 100. And in turn adjusts the matching circuits, e.g., the first matching circuit 14, the second matching circuit 24, according to the relative positions of the first housing 30 and the second housing 40, so that the antenna performance of the antenna assembly 100 is at an optimal state. For example, when the operating frequency band of the antenna assembly 100 deviates from the target frequency band, the matching circuits, such as the first matching circuit 14 and the second matching circuit 24, are adjusted according to the branch length a, so that the operating frequency band of the antenna assembly 100 is the target frequency band at this time. In still further embodiments, tuning control circuits such as a first tuning control circuit, a second tuning control circuit, a third tuning control circuit, and a fourth tuning control circuit may be adjusted according to the relative positions of the first housing 30 and the second housing 40 to optimize the antenna performance of the antenna assembly 100. For example, when the operating frequency band of the antenna assembly 100 deviates from the target frequency band, tuning control circuits such as the first tuning control circuit, the second tuning control circuit, the third tuning control circuit, and the fourth tuning control circuit are adjusted so that the operating frequency band of the antenna assembly 100 is the target frequency band.
