The antenna assembly 100 can be one or more of the following: a flexible printed circuit (FPC) antenna, a laser direct-structuring (LDS) antenna, a printed direct-structuring (PDS) antenna, and a metal frame antenna. Of course, the antenna assembly 100 can also be other types of antennas, which will not be elaborated upon. This application uses a metal frame antenna as an example for description.

[0050] Antenna assembly 100 may include a first radiator 10, a second radiator 20, a first feed 30 for exciting the first radiator 10, a first matching circuit 40 electrically connected between the first radiator 10 and the first feed 30, a second feed 50 for exciting the second radiator 20, and a frequency selection circuit 60 electrically connected between the second radiator 20 and the second feed 50. The first feed 30 is electrically connected to the first radiator 10 via the first matching circuit 40. The first feed 30 can exciting the first radiator 10 to support a first frequency band. The second feed 50 is electrically connected to the second radiator 20 via the frequency selection circuit 60. The second feed 50 can exciting the second radiator 20 to support a second frequency band. Antenna assembly 100 can achieve a multi-band design by coordinating the first and second frequency bands, thus broadening the bandwidth and improving antenna performance.

[0051] The terms "first," "second," "third," etc., used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "third," etc., may explicitly or implicitly include at least one of those features.

[0052] The first radiator 10 can be, but is not limited to, an LDS radiator, an FPC radiator, a PDS radiator, or a metal dendrite radiator. The shape, structure, and material of the first radiator 10 are not specifically limited. The shape of the first radiator 10 includes, but is not limited to, bent, strip, sheet, rod, coating, and thin film. When the first radiator 10 is strip-shaped, its extension trajectory is not limited; therefore, the first radiator 10 can extend in a straight line, curve, or with multiple bends. The first radiator 10 can be a line of uniform width along its extension trajectory, or a strip of varying width, such as one with gradually changing width or widened areas.

[0053] The first radiator 10 has a first free end 11, a feed point (e.g., first feed point 12), and a first ground point 13. The first ground point 13 is electrically connected to ground in ways including but not limited to direct electrical connection (e.g., soldering), or indirect electrical connection via coaxial cable, microstrip line, RF line, conductive spring, conductive adhesive, insert metal, etc. The feed point, for example, the first feed point 12, may be located between the first free end 11 and the first ground point 13. It is understood that the specific location of the feed point, for example, the first feed point 12, on the first radiator 10 is not limited.

[0054] 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 the side of the first ground point 13 away from the feed point, such as the first feed point 12. In some embodiments, the first end 14 is provided with the first ground point 13, that is, the first ground point 13 is located at the first end 14. In some embodiments, the radiating portion on the first radiator 10 located between the first ground point 13 and the first end 14 may be omitted, so that the first ground point 13 is located at the end.

[0055] In some embodiments, the two ends of the first radiator 10 (e.g., the first free end 11 and the first end 14, or the first free end 11 and the first grounding point 13) may each have a gap between themselves and other components. In some scenarios, when the antenna assembly 100 is applied in an electronic device, the gaps (i.e., the two gaps) between the two ends of the first radiator 10 and other components in the electronic device are not easily blocked or obstructed simultaneously. Even if one of the two gaps is blocked, the first radiator 10 can still transmit and receive electromagnetic wave signals; therefore, the antenna assembly 100 has good communication performance.

[0056] Please see Figure 1 The second radiator 20 has a second free end 21, a feed point (e.g., a second feed point 22), and a second ground point 23. The second ground point 23 is electrically connected to ground in ways including but not limited to direct electrical connection (e.g., soldering), or indirect electrical connection via coaxial cable, microstrip line, RF line, conductive spring, conductive adhesive, insert metal, etc. The feed point, for example, the second feed point 22, may be located between the second free end 21 and the second ground point 23. It is understood that the specific location of the feed point, for example, the second feed point 22, on the second radiator 20 is not limited.

[0057] In some embodiments, the second radiator 20 is further provided with a second end 24. In some embodiments, the second end 24 is located on the side of the second ground point 23 away from the feed point, such as the second feed point 22. In some embodiments, the second end 24 is provided with the second ground point 23, that is, the second ground point 23 is located at the second end 24. In some embodiments, the radiating portion on the second radiator 20 located between the second ground point 23 and the second end 24 may be omitted, so that the second ground point 23 is located at the end.

[0058] In some embodiments, the two ends of the second radiator 20 (e.g., the second free end 11 and the second end 24, or the second free end 11 and the second grounding point 23) may each have a gap between themselves and other components. In some scenarios, when the antenna assembly 100 is applied in an electronic device, the gaps (i.e., the two gaps) between the two ends of the second radiator 20 and other components in the electronic device are not easily blocked or obstructed simultaneously. Even if one of the two gaps is blocked, the second radiator 20 can still transmit and receive electromagnetic wave signals; therefore, the antenna assembly 100 has good communication performance.

[0059] Please see Figure 1 The first feed source 30 may be indirectly connected to a feed point, such as the first feed point 12, via a first matching circuit 40. The first feed source 30 may excite the first radiator 10 to support at least one of the following frequency bands: GPS band, WiFi band, low frequency band, mid-high frequency band, and NR (New Radio) band. In some embodiments, the first feed source 30 may excite the first radiator 10 to support a first frequency band.

[0060] In some embodiments, the first frequency band may be a mid-to-high frequency band or a low frequency band.

[0061] In some embodiments, the first frequency band may be a WiFi frequency band. In some embodiments, the first frequency band may include a WiFi 2.4G frequency band.

[0062] In some embodiments, the first frequency band may include 2.4 GHz.

[0063] In some embodiments, the first feed 30 can excite the first radiator 10 to generate a first resonant mode that supports a first frequency band.

[0064] In some embodiments, the first resonant mode is an inverted-F antenna (IFA) mode. In some embodiments, the first resonant mode is a composite left- and right-handed antenna mode (a mode with a composite left- and right-handed transmission line structure). In some embodiments, the first resonant mode is a quarter-wavelength mode, which is a relatively efficient resonant mode, thus enhancing the transmission and reception efficiency of the frequency band supported by the first resonant mode. 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.

[0065] 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.

[0066] Please see Figure 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 consist of a switch control circuit and / or a load circuit, or a variable capacitor (which may also be replaced by a fixed capacitor) and / or a variable inductor (which may also be replaced by a fixed inductor). In one embodiment, the switch control circuit may be a switch chip with switching function, or a single-pole multi-throw switch or a single-pole single-throw switch.

[0067] Please see Figure 1 The second feed source 50 can be indirectly connected to a feed point, such as the second feed point 22, via a frequency selection circuit 60. The second feed source 50 can excite the second radiator 20 to support at least one of the following frequency bands: GPS band, WiFi band, low frequency band, mid-to-high frequency band, and NR (New Radio) band. In some embodiments, the second feed source 50 can excite the second radiator 20 to support a second frequency band.

[0068] In some embodiments, the second frequency band may be a mid-to-high frequency band or a low frequency band.

[0069] In some embodiments, the second frequency band may include 1.6 GHz.

[0070] In some embodiments, the second feed 50 can excite the second radiator 20 to generate a second resonant mode supporting the second frequency band. In some embodiments, the second resonant mode is an inverted-F antenna (IFA) mode. In some embodiments, the second resonant mode is a composite left-handed antenna mode (a mode with a composite left-handed transmission line structure). In some embodiments, the second resonant mode is a quarter-wavelength mode, which is a relatively efficient resonant mode, thus enhancing the transmission and reception efficiency of the frequency band supported by the second resonant mode. 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.

[0071] In some embodiments, the current I2 of the second resonant mode is distributed between the second free end 21 and the second grounding point 23.

[0072] Please see Figure 1 The frequency selection circuit 60 is electrically connected between the feed point (e.g., the second feed point 22) and the second feed source 50. That is, the second feed source 50 can be electrically connected to the feed point, such as the second feed point 22, through the frequency selection circuit 60. The frequency selection circuit 60 can be directly grounded.

[0073] The frequency selection circuit 60 can be used to adjust the frequency of the second frequency band. In some embodiments, the frequency selection circuit 60 may consist of a switch control circuit and / or a load circuit, or a variable capacitor (which may also be replaced by a fixed capacitor) and / or a variable inductor.

[0074] Please see Figure 1 The first radiator 10 and the second radiator 20 can be capacitively coupled to be in a capacitive coupling state. In some embodiments, the first radiator 10 and the second radiator 20 can be arranged side by side to capacitively couple, forming a distributed capacitive coupling structure. The current I1 on the first radiator 10 is fed into the second radiator 20 in a 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 source 30. Thus, the second radiator 20 can increase the overall system efficiency of the first feed source 30 in the capacitive coupling state. In addition, the effect of widening the bandwidth can also be achieved through the third frequency band. Understandably, the current I2 on the second radiator 20 can also be fed into the first radiator 10 in a capacitive coupling manner to increase the overall system efficiency of the second feed source 50. This will not be elaborated further; for details, please refer to the introduction on the increase of the overall system efficiency of the first feed source 30 by the second radiator 20 in the capacitive coupling state.

[0075] In one embodiment, the third frequency band may include at least one of the following: GPS band, WiFi band, low frequency band, mid-to-high frequency band, and NR (New Radio) band.

[0076] In some embodiments, the third frequency band may be a mid-to-high frequency band or a low frequency band.

[0077] In some embodiments, the third frequency band may be WiFi 2.4GHz.

[0078] In some embodiments, the third frequency band may include 2.4 GHz.

[0079] In some embodiments, the first feed 30 can excite the second radiator 20 to generate a third resonant mode that supports the third frequency band.

[0080] In some embodiments, the current I3 of the third resonant mode is distributed between the second free end 21 and the second grounding point 23.

[0081] In one embodiment, the circuit in the frequency selection circuit 60 used to connect the feed point (e.g., the second feed point 22) to ground is turned on when the first feed source 30 excites the second radiator 20, and turned off when the second feed source 50 excites the second radiator 20, so as to improve the isolation between the first feed source 30 and the second feed source 50.

[0082] In one embodiment, the circuit in the frequency selection circuit 60 used to connect the second radiator 20 and the feed point (e.g., the second feed point 22) is disconnected when the first feed source 30 excites the second radiator 20, and connected when the second feed source 50 excites the second radiator 20, so as to improve the isolation between the first feed source 30 and the second feed source 50.

[0083] Understandably, while improving the isolation between the first feed source 30 and the second feed source 50, the frequency selection circuit 60 can 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 a capacitive coupling state.

[0084] Please see Figure 2 , Figure 2 for Figure 1 The diagram shows a schematic of the frequency selection circuit 60 in some embodiments. The frequency selection circuit 60 may include a second matching circuit 61 electrically connected to the second feed source 50, a first filter circuit 62 electrically connected between the feed point (e.g., the second feed point 22) and the second matching circuit 61, and a second filter circuit 63 electrically connected between the feed point (e.g., the second feed point 22) and ground. The second feed source 50 is electrically connected to the second radiator 20 through the second matching circuit 61 and the first filter circuit 62. The second radiator 20 is grounded through the second filter circuit 63.

[0085] In some embodiments, the second matching circuit 61 and the first filter circuit 62 can serve as the circuit in the frequency selection circuit 60 used to connect the second radiator 20 and the second feed source 50. That is, the circuit composed of the second matching circuit 61 and the first filter circuit 62 is disconnected when the first feed source 30 excites the second radiator 20, and connected when the second feed source 50 excites the second radiator 20, thereby improving the isolation between the first feed source 30 and the second feed source 50. In some embodiments, the first filter circuit 62 is disconnected when the first feed source 30 excites the second radiator 20, and connected when the second feed source 50 excites the second radiator 20, thereby improving the isolation between the first feed source 30 and the second feed source 50.

[0086] In some embodiments, the second filter circuit 63 can 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 a capacitive coupling state.

[0087] In some embodiments, the second filter circuit 63 can be used as a circuit in the frequency selection circuit 60 to connect the second radiator 20 to ground. That is, the second filter circuit 63 is turned on when the first feed source 30 excites the second radiator 20, and turned off when the second feed source 50 excites the second radiator 20, so as to improve the isolation between the first feed source 30 and the second feed source 50.

[0088] In some embodiments, the second matching circuit 61 can be used to adjust the frequency of the second frequency band. In some embodiments, the second matching circuit 61 may consist of a switch control circuit and / or a load circuit, or consist of an adjustable capacitor (which may also be replaced by a fixed capacitor) and / or an adjustable inductor.

[0089] In some embodiments, the first filter circuit 62 may include a first inductor L1 electrically connected between a feed point (e.g., the second feed point 22) and a first matching circuit 61, and a first capacitor C1 electrically connected between the feed point (e.g., the second feed point 22) and the first matching circuit 61. The first capacitor C1 and the first inductor L1 are connected in parallel, such that the first matching circuit 61 is electrically connected to the feed point (e.g., the second feed point 22) through the first capacitor C1 and the first inductor L1, respectively. The first capacitor C1 and the first inductor L1 may form a filter circuit.

[0090] In some embodiments, the second filter circuit 63 may include a grounded second inductor L2, a second capacitor C2 electrically connected between the feed point (e.g., second feed point 22) and the second inductor L2, and a third inductor L3 electrically connected between the feed point (e.g., second feed point 22) and the second inductor L2. The second capacitor C2 and the third inductor L3 are connected in parallel. The feed point (e.g., second feed point 22) is electrically connected to the second inductor L2 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.

[0091] Please see Figure 3 , Figure 3 for Figure 2 The diagram shows a schematic of the frequency selection circuit 60 in some embodiments. The second inductor L2 can be replaced by a third capacitor C3. That is, the second filter circuit 63 may include a grounded third capacitor C3, a second capacitor C2 electrically connected between the feed point (e.g., the second feed point 22) and the third capacitor C3, and a third inductor L3 electrically connected between the feed point (e.g., the second feed point 22) and the third capacitor C3. The second capacitor C2 and the third inductor L3 are connected in parallel. The feed point (e.g., the second feed 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 can form a filter circuit.

[0092] Please see Figure 1The first radiator 10 and the second radiator 20 may be strip-shaped. The first end 14 and the second free end 21 may both be located on one side of the line connecting the first free end 11 and the second end 24, that is, the first free end 11 and the second end 24 are both located on one side of the line connecting the first end 14 and the second free end 21.

[0093] 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 grounding point 13 onto the second radiator 20 may coincide with the second free end 21. For example, if the first grounding point 13 is located at the first end 14, that is, the first grounding point 13 is the end point, then the orthographic projection of the first grounding point 13 onto the second radiator 20 may coincide with the second free end 21.

[0094] 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 onto the first radiator 10 may coincide with the first grounding point 13. For example, in some scenarios, the first grounding point 13 is located at the first end 14, that is, the first grounding point 13 is the end point, then the orthographic projection of the second free end 21 onto the first radiator 10 may coincide with the first grounding point 13.

In some embodiments, the orthographic projection of the second grounding point 23 onto the first radiator 10 may coincide with the first free end 11. For example, if the second grounding point 23 is located at the second end 24, that is, if the second grounding point 23 is the end point, then the orthographic projection of the second grounding point 23 onto the first radiator 10 coincides with the first free end 11.

[0096] 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 onto the second radiator 20 may coincide with the second grounding point 23. For example, the second grounding point 23 is located at the second end 24, that is, the second grounding point 23 is the end point, and the orthographic projection of the first free end 11 onto the second radiator 20 may coincide with the second grounding point 23.

[0097] Please refer to the following: Figure 1 , Figure 4 and Figure 5 , Figure 4 for Figure 1 The schematic diagram shown is a structural representation of the antenna assembly 100 in another embodiment. Figure 5 for Figure 1 The diagram shows the structure of the antenna assembly 100 in another embodiment. Figure 4The first radiator 10 and the second radiator 20 are in a capacitive coupling state, and the length of the coupling branch is L1. When the first radiator 10 and the second radiator 20 slide relative to each other, the length of the coupling branch L1 can be adjusted. For example, if the first radiator 10 moves closer to the second free end 21, increasing the length of the coupling branch L1, it can move to... Figure 1 The capacitive coupling state in the process. For example, the first radiator 10 moves away from the second free end 21, reducing the length L1 of the mutually coupled branches, and can move to...

[0098] In some embodiments, Figure 5 The first radiator 10 and the second radiator 20 are in a non-capacitive coupling state, that is, the current I1 on the first radiator 10 cannot be fed into the second radiator 20 in a capacitive coupling manner, and similarly, the current I2 on the second radiator 20 cannot be fed into the first radiator 10 in a capacitive coupling manner.

[0099] Please refer to the following: Figure 1 and Figure 6 , Figure 6 for Figure 1 The diagram shows the structure of the antenna assembly 100 in another embodiment. Figure 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-capacitive coupling state. The distance L2 can be adjusted when the first radiator 10 and the second radiator 20 slide relative to each other. For example, Figure 1 The first radiator 10 moves away from the second radiator 20, increasing the distance L2, and can move to... Figure 6 Non-capacitive coupling states in [the system]. For example, Figure 6 The first radiator 10 moves towards the side closer to the second radiator 20, reducing the distance L2, and can move to... Figure 1 The capacitive coupling state in the middle.

[0100] Please see Figure 7 , Figure 7 for Figure 1 The diagram shows a structural schematic of the antenna assembly 100 in some other embodiments. The first radiator 10 may be bent. The first free end 11 and the first end 14 may not be opposite each other in a straight line. However, the first free end 11 and the first end 14 may be the two ends of the first radiator 10. It can be understood that the first free end 11 and the first end 14 may be the opposite ends of the first radiator 10, which is in the shape of a straight strip.

[0101] The first radiator 10 may include a first part 101 and a second part 102 that are bent and connected together. The first part 101 may have a first free end 11, and the second part 102 may have a first end 14. The first part 101 and the second part 102 are connected, and the point where they intersect is a first intersection point 103. A first feed point 12 is located in the first part 101. A first ground point 13 is located in the second part 102.

[0102] Please see Figure 7 The second radiator 20 may be bent. The second free end 21 and the second end 24 may not be opposite each other in a straight line. However, the second free end 21 and the second end 24 may be the two ends of the second radiator 20. It is understood that the second free end 21 and the second end 24 may be the opposite ends of the second radiator 20, which is in the shape of a straight strip.

[0103] The second radiator 20 may include a third part 201 and a fourth part 202 that are bent and connected. The third part 201 may have a second free end 21, and the fourth part 202 may have a second end 24. The third part 201 and the fourth part 202 are connected, and the point where they intersect is a second intersection point 203. The second feed point 22 is located in the third part 201. The second grounding point 23 is located in the fourth part 202.

[0104] Please see Figure 7 The first radiator 10 and the second radiator 20 are in a capacitive coupling state. In some embodiments, the extending direction of the first part 101 is consistent with the extending direction of the fourth part 202. It is understood that the extending direction of the first part 101 may also be consistent with the extending direction of the third part 201. For example, the extending direction of the third part 201 may be consistent with the extending direction of the fourth part 202. Alternatively, the extending direction of the first part 101 may be consistent with the extending direction of the second part 102, and the extending direction of the second part 102 may be consistent with the extending direction of the third part 201.

[0105] Please see Figure 7 The first radiator 10 and the second radiator 20 are in a capacitive coupling state. In some embodiments, the extension direction of the second part 102 is consistent with the extension direction of the third part 201. It can be understood that the extension direction of the second part 102 may also be consistent with the extension direction of the fourth part 202. For example, the extension direction of the third part 201 is consistent with the extension direction of the fourth part 202. For example, the extension direction of the second part 102 is consistent with the extension direction of the first part 101, and the extension direction of the first part 101 is consistent with the extension direction of the fourth part 202.

[0106] Please see Figure 7 The extension directions of the first part 101 and the fourth part 202 are on different straight lines, so that the first part 101 and the fourth part 202 are set in parallel.

[0107] Please see Figure 7The extension direction of the second part 102 and the extension direction of the third part 201 are on different straight lines, so that the second part 102 and the third part 201 are set in parallel.

[0108] Please see Figure 7 The first radiator 10 is capacitively coupled to the second radiator 20 at the first portion 101 and the second portion 102, respectively, to be in a capacitively coupled state. The second radiator 20 is capacitively coupled to 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 to the second radiator 20 at least at the first portion 101, for example, the fourth portion 202, to be in a capacitively coupled state. In some embodiments, the first radiator 10 may be capacitively coupled to the second radiator 20 at least at the second portion 102, for example, the third portion 201, to be in a capacitively coupled state. In some embodiments, the second radiator 20 may be capacitively coupled to the first radiator 10 at least at the first portion 101, for example, the fourth portion 202, to be in a capacitively coupled state.

[0109] Understandably, Figure 7 The first radiator 10 and the second radiator 20 in the middle can also be like Figure 4 , Figure 6 The relative sliding shown, and the transition between capacitive coupling and non-capacitive coupling states, will not be elaborated here.

[0110] In some scenarios, please refer to Figure 8 , Figure 8 for Figure 7 The diagram shows a structural schematic of the antenna assembly 100 in another embodiment. A first part 101 is disposed on the side of the second part 102 near the second radiator 20. The first part 101 extends towards the second radiator 20. A fourth part 202 is disposed on the side of the third part 201 near the first radiator 10. The fourth part 202 extends towards the second part 102. The first radiator 10 and the second radiator 20 are in a non-capacitive coupling state. A fold line M is provided between the first part 101 and the second part 102. The second radiator 20 can rotate relative to the first radiator 10 about the fold line M, and can rotate until the first radiator 10 and the second radiator 20 are in a capacitive coupling state, for example... Figure 7 The capacitive coupling state is shown. That is, the first radiator 10 can also rotate relative to the second radiator 20 about the fold line M, and can rotate until the first radiator 10 and the second radiator 20 are in a capacitive coupling state. It can be understood that the arrangement of the first radiator 10 and the second radiator 20 is not limited to... Figure 8The state shown can also be other forms, and can be achieved by rotating the second radiator 20 relative to the first radiator 10 about the fold line M, until the first radiator 10 and the second radiator 20 are in a capacitive coupling state, for example... Figure 7 The state shown. Or, the first radiator 10 rotates relative to the second radiator 20 about the fold line M, and rotates until the first radiator 10 and the second radiator 20 are in a capacitive coupling state, for example. Figure 7 The state shown.

[0111] Please see Figure 9 , Figure 9 for Figure 7 The diagram shows the return loss curves of the antenna assembly 100 in some embodiments, with the horizontal axis representing frequency (GHz) and the vertical axis representing return loss (dB). 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 both the first feed 10 and the second feed 20.

[0112] Curve A has a first marker point (2.4704, -11.955) and a second marker point (2.3102, -12.663). On curve A, the first marker point (2.4704, -11.955) corresponds to the frequency band supported by the first resonant mode, and the second marker point (2.3102, -12.663) corresponds to the frequency band supported by the third resonant mode. Therefore, the antenna assembly 100 exhibits good antenna performance near 2.4 GHz, meaning it performs well in the vicinity of the first frequency band. Furthermore, the combination of the first and third frequency bands can broaden the bandwidth of the antenna assembly 100. Consequently, the antenna assembly 100 operates well and meets engineering requirements. Additionally, the bandwidth composed of the first and / or third frequency bands can be adjusted by regulating the frequency selection circuit 60, such as the second filter circuit 63.

[0113] A third marker point (1.5908, -6.3951) is located on curve B. This third marker point (1.5908, -6.3951) represents the frequency band supported by the second resonant mode. It can be seen that the antenna assembly 100 exhibits good antenna performance near 1.6 GHz, meaning that the antenna assembly 100 performs well near the second frequency band. Furthermore, the antenna assembly 100 operates well and meets engineering requirements.

[0114] The curve C has a second marker point (2.3102, -12.663). It can be seen that the first feed 10 and the second feed 20 have good isolation near 2.4 GHz, i.e., near the first frequency band. Similarly, they have good isolation near the third marker point, i.e., near the second frequency band.

[0115] Please see Figure 10 , Figure 10 for Figure 7 Antenna assembly 100 and shown Figure 8 The diagram shows a comparison of the system total efficiency curves of the antenna assembly 100 in some embodiments. The horizontal axis represents frequency (GHz), and the vertical axis represents system total efficiency (dB). Curve D is... Figure 8 The system overall efficiency curve of the antenna assembly 100 shown in some embodiments is curve E. Figure 7 The diagram shows the overall system efficiency curves of the antenna assembly 100 in some embodiments. Curve E has a first marker point (2.4522, -2.5128) and a second marker point (2.3016, -3.1844), while curve D has a third marker point (2.3997, -4.2778). It is evident that the system efficiency of curve E is wider and higher than that of curve D, with a wider bandwidth and stronger tolerance.

[0116] The following describes an electronic device that can be equipped with the antenna assembly 100 in the above embodiments. This electronic device can be any of a plurality of electronic devices, including but not limited to cellular phones, smartphones, 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 Image Experts Group (MPEG-1 or MPEG-2), Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0117] In some embodiments, the electronic device may include, but is not limited to, electronic devices with communication functions such as mobile phones, mobile internet devices (MIDs), e-books, portable PlayStation Portable (PSPs), or personal digital assistants (PDAs).

[0118] Please refer to the following: Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the overall structure of the electronic device in its folded state in some embodiments of this application. Figure 12 yes Figure 11The diagram shows the unfolded state of the electronic device. The electronic device 300 may include a first housing 301 on which an antenna assembly 100, such as a first radiator 10, is disposed, a second housing 302 on which an antenna assembly 100, such as a second radiator 20, is disposed and slides relative to the first housing 301, and a flexible display screen 303 disposed on the first housing 301 and the second housing 302.

[0119] The first housing 301 can slide relative to the second housing 302, and can partially slide into the second housing 302 to achieve a retracted state. The first housing 301 can also slide relative to the second housing 302, and can partially slide out of the second housing 302 to achieve an unfolded state.

[0120] The first housing 301 and the second housing 302 can be used to house and mount electronic components such as a circuit board (on which control units, such as processors, are installed), a battery, a camera, and sensors. The flexible display screen 303 is bendable and can be electrically connected to the circuit board, such as control units and batteries, to display information such as images and text. When the first housing 301 and the second housing 302 slide relative to each other, the flexible display screen 303 can partially slide into or out of the first housing 301. The antenna assembly 100, such as the first radiator 10 and the second radiator 20, can be electrically connected to the circuit board, such as control units and batteries, to achieve antenna performance. The relative positions of the first radiator 10 and the second radiator 20 can be adjusted by the relative sliding of the first housing 301 and the second housing 302. This allows for different antenna performances of the antenna assembly 100, ensuring that the antenna assembly 100 operates in optimal condition at all times, thus improving the overall communication capability of the electronic device 300.

[0121] Understandably, the first housing 301 can slide relative to the second housing 302, adjusting the distance between the first radiator 10 and the second radiator 20, so that the first radiator 10 and the second radiator 20 are in a capacitive coupling state or a non-capacitive coupling state as described in the above embodiments. For example, the first radiator 10 and the second radiator 20 are in a capacitive coupling state in the retracted state, and in a non-capacitive coupling state in the deployed state. Alternatively, the first radiator 10 and the second radiator 20 are in a non-capacitive coupling state in the retracted state, and in a capacitive coupling state in the deployed state.

[0122] Furthermore, the first housing 301 and the second housing 302 can cooperate to form an adjustment assembly 200 to adjust the distance between the first radiator 10 and the second radiator 20. Of course, in some embodiments, the adjustment assembly 200 may not be limited to the first housing 301 and the second housing 302, and may include other structures. Conversely, in some embodiments, the adjustment assembly 200 may not include the first housing 301 and the second housing 302, but may be other structures. Any structure that can achieve the relative positional change of the first radiator 10 and the second radiator 20 can be provided in technical solutions well known to those skilled in the art, and will not be elaborated further. That is, as long as it can achieve… Figure 4 The structure for adjusting the branch length L1 of the coupling between the first radiator 10 and the second radiator 20 can be configured using techniques well-known to those skilled in the art. That is, as long as it can be achieved... Figure 6 The structure for adjusting the distance L2 between the first radiator 10 and the second radiator 20 can be set in technical solutions well known to those skilled in the art; that is, as long as it can achieve... Figure 8 The structures for adjusting the rotation of the first radiator 10 and the second radiator 20 around the fold line M can be configured using techniques well-known to those skilled in the art. In some scenarios, the first radiator 10 and / or the second radiator 20 are mounted on the adjustment assembly 200. In some scenarios, the first radiator 10 and / or the second radiator 20 are connected to the adjustment assembly 200.

[0123] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0124] Please see Figure 12 The first housing 301 may include a first ground surface 3011 and a first frame 3012 surrounding the edge of the first ground surface 3011. The first ground surface 3011 serves to support the flexible display screen 303. The first ground surface 3011 and the first frame 3012 cooperate to form a receiving space for accommodating the flexible display screen 303. The flexible display screen 303 can be bent into the receiving space for storage. When the first housing 301 and the second housing 302 slide relative to each other, the flexible display screen 303 partially slides and bends into the first housing 301.

[0125] The first ground plane 3011 can serve as a ground to be electrically connected to the first grounding point 13 in the antenna assembly 100 in the above embodiment. At least a portion of the edge of the first ground plane 3011 can be connected and fixed to the first frame 3012. Furthermore, in some scenarios, a first gap 3013 is formed between the first ground plane 3011 and the first frame 3012.

[0126] The first radiator 10 in the above embodiment is disposed 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 the first radiator 10 is electrically connected to the first ground plane 3011 at the first grounding point 13.

[0127] In some embodiments, the first frame 3012 is at least partially made of conductive metal, and thus may partially serve as the first radiator 10.

[0128] The second housing 302 can slide relative to the first housing 301. In some embodiments, the second housing 302 can be slidably connected to the first housing 301. Specifically, the slidable connection can be achieved by using a slide rail, roller, slider, etc.

[0129] Please see Figure 12 The second housing 302 includes a second ground surface 3021 and a second frame 3022 surrounding the edge of the second ground surface 3021. The second ground surface 3021 cooperates with the first housing 301, such as the first ground surface 3011, to jointly support the flexible display screen 303. The second ground surface 3021 and the second frame 3022 cooperate to form an accommodating space for accommodating the flexible display screen 303 and the first housing 301. The accommodating space can store a portion of the flexible display screen 303. When the first housing 301 and the second housing 302 slide relative to each other, a portion of the flexible display screen 303 slides or bends into the accommodating space, allowing the first housing 301 to slide into or out of the accommodating space. Simultaneously, the flexible display screen 303 can also slide or bend into the accommodating space.

[0130] The second ground plane 3021 can serve as a ground to be electrically connected to the second grounding point 23 in the antenna assembly 100 in the above embodiment. At least a portion of the edge of the second ground plane 3021 can be connected and fixed to the second frame 3022. Furthermore, in some scenarios, a second gap 3023 is formed between the second ground plane 3021 and the second frame 3022.

[0131] 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 the second radiator 20 is electrically connected to the second ground plane 3021 at the second grounding point 23.

[0132] In some embodiments, the second frame 3022 is at least partially made of conductive metal, and thus may partially serve as the second radiator 20.

[0133] Please see Figure 12 , Figure 13 and Figure 14 , Figure 13 for Figure 12A diagram showing the state of the first housing 301 and the second housing 302 sliding relative to each other in one embodiment. Figure 14 for Figure 12 The diagram shows the state of the first housing 301 and the second housing 302 sliding relative to each other in one embodiment. The first ground surface 3011 and the first frame 3012 of the first housing 301 are inserted into the receiving space of the second housing 302 on one side, so that the first housing 301 and the second housing 302 can slide. The first housing 301 can slide in and out of the receiving space of the second housing 302.

[0134] In one 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 decapacitively coupled and in a noncapacitively coupled state, allowing the first radiator 10 and the second radiator 20 in the antenna assembly 100 to be arranged according to... Figure 5 The antenna assembly 100 shown operates in resonant modes, such as the first resonant mode and the second resonant mode.

[0135] In one embodiment, the first housing 301 slides into the receiving space of the second housing 302 relative to the second housing 302 to be in a retracted state, so that the first radiator 10 and the second radiator 20 are in a capacitive coupling state, allowing the first radiator 10 and the second radiator 20 in the antenna assembly 100 to be arranged according to... Figure 1 The antenna assembly 100 shown operates in resonant modes, such as the first resonant mode, the second resonant mode, and the third resonant mode.

[0136] In some embodiments, when the first housing 301 and the second housing 302 are in a closed state, the orthographic projection of the first gap 101 on the second housing 302 at least partially overlaps with the second gap 102, or they may completely overlap.

[0137] Please see Figure 12 and Figure 15 , Figure 15 for Figure 12 The diagram shows a cross-sectional view of the electronic device 300. The flexible display screen 303 has a display surface and a non-display surface, for displaying information on the display surface side and disposed on the first housing 301 and the second housing 302 on the non-display surface side.

[0138] The flexible display screen 303 can be bent towards the non-display surface to achieve folding, forming a first folded portion 3031 and a second folded portion 3032 opposite to and connected to the first folded portion 3031. The surface of the first folded portion 3031 away from the second folded portion 3032 is the display surface. The surface of the second folded portion 3032 away from the first folded portion 3031 is also the display surface. The first folded portion 3031 can be disposed on the first ground surface 3011 and the second ground surface 3021. The second folded portion 3032 can be placed within the receiving space, or within both the receiving space and the accommodating space. When the first housing 301 and the second housing 302 slide relative to each other, the second folded portion 3032 can slide out from the receiving space to become part of the first folded portion 3031, and the first folded portion 3031 can slide into the receiving space to become part of the second folded portion 3032. In some scenarios, when the first housing 301 and the second housing 302 slide relative to each other, the second folded portion 3032 of the flexible display screen 303 will gradually slide out from 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 relative to each other, the first folded portion 3031 of the flexible display screen 303 will extend into the receiving space to reduce the display area of ​​the first folded portion 3031.

[0139] Understandably, the first radiator 10 and the second radiator 20 are not limited to Figure 11 The setup shown can also be configured on the first housing 301 and the second housing 302 according to the cooperation relationship between the first radiator 10 and the second radiator 20 in the above embodiment.

[0140] Please see Figure 16 , Figure 16 for Figure 11 The illustrated electronic device 100 is a schematic diagram of its structure in some other embodiments. The second radiator 20 can be as follows: Figure 7 As shown, the second radiator 20 may include a third part 201 and a fourth part 202 that are bent and connected. The third part 201 may have a second free end 21, and the fourth part 202 may have a second end 24. The third part 201 and the fourth part 202 are connected, and the point where they intersect is a second intersection point 203. The second feed point 22 is located in the third part 201. The second grounding point 23 is located in the fourth part 202.

[0141] 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 part 201, are decoupled 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 are in accordance with Figure 5 The antenna assembly 100 shown operates in resonant modes, such as the first resonant mode and the second resonant mode.

[0142] In one embodiment, the first housing 301 slides into the receiving space of the second housing 302 relative to the second housing 302 to be in a retracted state, so that the first radiator 10 and the second radiator 20, for example, the third part 201, are in a capacitive coupling state, such that the first radiator 10 and the second radiator 20 in the antenna assembly 100 are in accordance with... Figure 1 The antenna assembly 100 shown operates in resonant modes, such as the first resonant mode, the second resonant mode, and the third resonant mode.

[0143] In some embodiments, the first radiator 10 may also be configured to... Figure 7 The design is as shown, and thus the first radiator 10 and the second radiator 20 can be designed according to... Figure 7 The following actions are to be performed as shown.

[0144] Understandably, the connection between the first housing 301 and the second housing 302 is not limited to a sliding connection. It can also be other connection methods. The first housing 301 and the second housing 302 can be folded to be in a folded or unfolded state. For example, please refer to... Figure 16 and Figure 17 , Figure 17 for Figure 16 An exploded view of the electronic device 600. The electronic device 600 may include a first housing 601 and a second housing 602 for mounting an antenna assembly 100, a folding portion 603 connecting the first housing 601 and the second housing 602, and a flexible display screen 604 disposed on the first housing 601, the second housing 602, and the folding portion 603. The folding portion 603 connects the first housing 601 and the second housing 602, and may have the folding line M as described in the above embodiments. The folding portion 603 is used to fold the electronic device 600 so that the first housing 601 and the second housing 602 are stacked and folded, or so that the first housing 601 and the second housing 602 are located on both sides of the folding portion and unfolded, 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 unfolded relative to each other, in an unfolded state, or folded, in a folded state.

[0145] The first housing 601 and the second housing 602 can be used to house and mount electronic components such as a circuit board (which houses control units such as processors), a battery, a camera, and sensors. The flexible display screen 303 is bendable and can be electrically connected to the circuit board, such as control units and batteries, to display information such as images and text. The flexible display screen 604 can be folded or unfolded when the first housing 601 and the second housing 602 are folded relative to each other. The antenna assembly 100, such as the first radiator 10 and the second radiator 20, can be electrically connected to the circuit board, such as control units and batteries, 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 around the folding line M. This allows for different antenna performances of the antenna assembly 100, ensuring that the antenna assembly 100 operates in optimal condition at all times and improving the overall communication capability of the electronic device 600.
