[0031] Exemplary embodiments of this disclosure will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure.

Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0032] The embodiments described below, which are examples of some of the embodiments of this disclosure, do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0034] Figure 1 This is a structural diagram of an antenna assembly according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the antenna assembly 100 includes a first radiator 1, a second radiator 2, a first feed 3 and a second feed 4, a first switching circuit 5 and a second switching circuit 6.

[0035] The first radiator 1 includes a first free end 11 and a first feed point 12. For example, as shown... Figure 1 As shown, the first radiator 1 also includes a first grounding terminal 13. The first grounding terminal 13 is disposed opposite to the first free terminal 11, and the first feed point 12 is disposed between the first grounding terminal 13 and the first free terminal 11.

[0036] In this embodiment, the first feed source 3 is electrically connected to the first feed point 12. When the first feed source 3 transmits signal energy to the first radiator 1 through the first feed point 12, the first radiator 1 will generate electromagnetic wave radiation under the excitation of the first feed source 3.

[0037] The second radiator 2 includes a second free end 21 and a second feed point 22. For example, as shown... Figure 1 As shown, the second radiator 2 also includes a second grounding terminal 23. The second grounding terminal 23 is disposed opposite to the second free terminal 21, and the second feed point 22 is disposed between the second grounding terminal 23 and the second free terminal 21.

[0038] In this embodiment, the second feed source 4 is electrically connected to the second feed point 22. When the second feed source 4 transmits signal energy to the second radiator 2 through the second feed point 22, the second radiator 2 will generate electromagnetic wave radiation under the excitation of the second feed source 4.

[0039] In this embodiment, the antenna structure of the first radiator and the second radiator is an IFA (Inverted-Fantenna) antenna structure. Of course, other antenna structures, such as a T-antenna structure, can also be used according to actual needs, and there is no limitation on this.

[0040] like Figure 1 As shown, the first free end 11 of the first radiator 1 and the second free end 21 of the second radiator 2 form a coupling gap. When the first radiator 1 is excited, its radiated energy is not only directly radiated out through the first radiator 1, but also coupled with the second radiating branch 2 through the gap. When the second radiating branch 2 is excited, a positive coupling effect is generated to the first radiator 1.

[0041] The antenna assembly of this embodiment supports different frequency bands through a first radiator 1 and a second radiator 2. A first feed point 12 is provided on the first radiator 1, and a second feed point 22 is provided on the second radiator 2. The first radiator 1 and the second radiator 2 form a coupling gap, so that the first radiator 1 and the second radiator 2 can be parasitic on each other, thereby enhancing the overall radiation efficiency of the antenna assembly.

[0042] In this embodiment of the disclosure, the first radiator 1 further includes a tuning point 14, and the first switching circuit 5 is electrically connected to the tuning point 14. For example... Figure 1 As shown, one end of the first switching circuit 5 is electrically connected to the tuning point 14, and the other end is grounded.

[0043] The distance between tuning point 14 and the first free end 11 is less than the distance between the first feed point 12 and the first free end 11. For example, tuning point 14 can be set between the first feed point 12 and the first free end 11, or it can be set at the first free end 11. The first tuning point 14 is electrically connected to the first switching circuit 5, enabling aperture tuning, which in turn tunes the standing wave ratio and tuning efficiency.

[0044] Aperture tuning is a method of adjusting antenna performance by changing parameters in the antenna structure. In this embodiment, the tuning point 14 is located on the first radiator 1 near the gap. The first switching circuit 5 is electrically connected to the tuning point 14. By switching the state of the first switching circuit 5, such as on, off, or different resistance or capacitance values, the "aperture" of the antenna structure is adjusted, thereby adjusting the operating state of the first radiator 1, affecting the path and manner of current passing through the first radiator 1, optimizing the standing wave ratio of the first radiator 1, and improving the tuning efficiency of the first radiator 1.

[0045] In this embodiment of the disclosure, the second switching circuit 6 is electrically connected between the second feed source 4 and the second feed point 22, and the second switching circuit 6 performs impedance tuning.

[0046] like Figure 1 As shown, one end of the first switching circuit 6 is electrically connected between the second feed source 4 and the second feed point 22, and the other end is grounded. That is, the second switching circuit 6 is introduced at the second feed point 22 of the second radiator 2. By switching the state of the second switching circuit 6, such as on, off, or different resistance or capacitance values, the impedance characteristics of the second radiator 2 are dynamically adjusted, that is, the operating state of the second radiator 1 is adjusted, thereby optimizing the standing wave ratio and efficiency of the second radiator 2.

[0047] In this embodiment of the disclosure, the first radiator 1 and the second radiator 2 are parasitic on each other. Therefore, by switching the state of the second switching circuit 6, such as turning on, turning off, or different resistance or capacitance values, different electroparasitic effects can be introduced into the first radiator 1, affecting the current distribution and radiation characteristics of the first radiator 1, thereby improving the efficiency of the first radiator 1.

[0048] The antenna assembly provided in this disclosure uses a first radiator and a second radiator to support multiple frequency bands; a coupling gap is formed between the first radiator and the second radiator, so that the first radiator and the second radiator can be mutually parasitic, thereby enhancing the overall radiation efficiency of the antenna assembly; a first switching circuit and a second switching circuit are introduced, which can flexibly adjust the working state of the antenna, optimize the performance of the antenna in different frequency bands, and meet the needs of electronic devices for multi-band and high-performance antennas.

[0049] Specifically, the first switching circuit, electrically connected to the tuning point on the first radiator, achieves aperture tuning, optimizes the VSWR of the first radiator, and improves its tuning efficiency. The second switching circuit, electrically connected between the second feed source and the second feed point, enables impedance tuning. By switching the state of the second switching circuit, the impedance characteristics of the second radiator can be dynamically adjusted, further optimizing its VSWR and efficiency. Furthermore, the introduction of the second switching circuit also brings additional electrical parasitic effects to the first radiator. By changing the state of the second switching circuit, the current distribution and radiation characteristics of the first radiator can be affected, thereby improving its efficiency at different frequency bands.

[0050] In some embodiments of this disclosure, the operating frequency band of the first radiator includes the MHB (Middle High Band) band, and the operating frequency band of the second radiator includes the LB (Low Band) and N77 (a band used in 5G communication).

[0051] It is understood that the frequency bands in which the first radiator and the second radiator operate are only examples. The specific range of operating frequency bands and which radiator each frequency band operates on are not limited in this disclosure. For example, the operating frequency bands of the second radiator 2 include the LB band and the N78 band (the band in 5G communication).

[0052] In an exemplary embodiment, if the operating frequency band of the first radiator 1 is the MHB band and the operating frequency bands of the first radiator 2 are the LB band and the N77 band, a coupling gap is formed between the first radiator 1 and the first radiator 2. This may result in strong coupling between the two radiators in the MHB and N77 bands, affecting the performance of the MHB and N77 bands, especially leading to poor performance in key frequency bands such as B3, B41, and N77. The antenna assembly of this embodiment introduces a first switching circuit 5 near the gap on the first radiator 1 and a second switching circuit 6 at the feed point of the second radiator 2. These two switching circuits can be used to flexibly adjust the antenna's operating state and optimize the antenna's performance in key frequency bands such as B3, B41, and N77.

[0053] In some embodiments of this disclosure, the distance between the tuning point 14 and the first free end 11 ranges from 0 to 8 mm. For example, the distance between the tuning point 14 and the first free end 11 may be 0 mm, 1 mm, 3 mm, 5 mm, 8 mm, etc.

[0054] In this embodiment of the disclosure, the distance between the tuning point 14 and the first free end 11 is set to a range of 0 to 8 mm. This range limits the distance between the tuning point 14 and the first free end 11 to be less than the distance between the first feed point 12 and the first free end 11. In other words, this range limits the tuning point 14 to be between the first feed point 12 and the first free end 11, or the tuning point 14 to be at the first free end 11.

[0055] In one possible implementation, such as Figure 2 As shown, the tuning point 14 is directly set at the first free end 11, that is, the distance between the tuning point 14 and the first free end 11 is 0mm, and the first switching circuit 5 is introduced through the tuning point 14.

[0056] In some embodiments of this disclosure, the distance between the tuning point 14 and the first free end 11 ranges from 1.2mm to 1.8mm. For example, the distance between the tuning point 14 and the first free end 11 is set to 1.2mm, 1.3mm, 1.5mm, 1.8mm, etc.

[0057] In practical applications, the first radiator 1 often needs to be connected to a circuit board. For example, certain connectors may be installed on the first free end 11. Due to the presence of such connectors, it is difficult to directly set the tuning point 14 at the first free end 11. Therefore, the position of the tuning point 14 can be optimized to ensure that the distance between the tuning point 14 and the first free end 11 is within the range of 1.2mm to 1.8mm. This satisfies performance requirements while avoiding interference with the connectors at the first free end 11.

[0058] The antenna assembly of this embodiment sets the distance between the tuning point and the first free end to a range of 0 to 8 mm. By introducing a first switching circuit through the tuning point, aperture tuning can be performed using the first switching circuit, which can tune the standing wave and tuning efficiency.

[0059] Furthermore, a tuning point is set at the first free end of the first radiator. By introducing the first switching circuit through this tuning point, the aperture tuning can be performed more effectively, improving the tuning accuracy, thereby optimizing the VSWR and improving the tuning efficiency.

[0060] Furthermore, the distance between the tuning point and the first free end is set to a range of 1.2mm to 1.8mm. By introducing the first switching circuit through the tuning point, not only is aperture tuning achieved using the first switching circuit, thereby adjusting the VSWR and improving tuning efficiency, but interference between the tuning point and any connecting parts that may exist on the first free end is also avoided, ensuring the reliability and stability of the antenna assembly.

[0061] In some embodiments of this disclosure, the first switching circuit includes a first switching component and a plurality of first tuning branches. The first switching component includes a plurality of first switching switches connected in parallel with each other, and each first switching switch is connected in series with any of the first tuning branches.

[0062] Figure 3 This is a structural diagram of another antenna assembly illustrated according to an exemplary embodiment of the present disclosure. Figure 3 As shown, the first switching circuit 5 includes a first switching assembly 51, which includes four sets of first switching switches connected in parallel, namely first switching switches 511 to 514. The first switching circuit 5 also includes four first tuning branches, namely first tuning branches 52 to 55.

[0063] Specifically, the first switching switch 511 is connected in series with the first tuning branch 52, the first switching switch 512 is connected in series with the first tuning branch 53, the first switching switch 513 is connected in series with the first tuning branch 54, and the first switching switch 514 is connected in series with the first tuning branch 55.

[0064] In this embodiment of the disclosure, one of the plurality of first tuning branches includes a first capacitor, wherein when a first switching switch connected in series with the first tuning branch switches to the on state, the first radiator switches to the first capacitor state.

[0065] like Figure 3 As shown, the first tuning branch 52 includes a first capacitor C1. When the first switching switch 511, which is connected in series with the first tuning branch 52, is turned on, the first tuning branch 52 (including the first capacitor C1) is connected to the circuit.

[0066] In the antenna assembly of this disclosure, one of the plurality of first tuning branches includes a first capacitor. When the first tuning branch including the first capacitor is connected to the circuit, the first radiator exhibits an electrical effect similar to that of a capacitor, that is, its impedance characteristics become similar to those of a capacitor at certain frequencies. In this case, the first radiator can be considered to be in a first capacitor state, which will affect the surrounding electromagnetic field distribution and thus affect the efficiency of the second radiator.

[0067] In an exemplary embodiment, the first radiator 1 operates in the MHB band, and the second radiator 2 operates in the LB and N77 bands. A tuning point 14 is added to the first radiator 1 near the first free end 11, for example, at a distance of 1.5 mm from the first free end 11. The tuning point 14 is then used to introduce a first switching circuit 5. The first switching circuit 5 includes a first switching switch 511 and a first tuning branch 52 connected in series with the first switching switch 511. The first tuning branch 52 includes a first capacitor C1. When the first switching switch 511 is turned on, the first tuning branch 52, including the first capacitor C1, is connected to the circuit. In this case, the first radiator 1 exhibits a capacitor-like effect, that is, the first radiator 1 is in the first capacitor state. The electromagnetic field generated will interfere with the higher-order modes of the second radiator 2 in the N77 frequency band. This interference causes the second radiator 2 to operate more in the radiating intrinsic mode and the electroparasitic mode when it is in the N77 frequency band, which can improve the efficiency of the second radiator 2 in the N77 frequency band.

[0068] In some embodiments of this disclosure, the other first tuning branches besides one of the plurality of first tuning branches include a first inductor. The inductance values ​​of the first inductors in different first tuning branches may be the same or different.

[0069] like Figure 3 As shown, apart from the first tuning branch 52, the tuning elements in the other first tuning branches 53 to 55 are the first inductors L1, L2, and L3, respectively. For example, the inductance values ​​of the first inductors L1, L2, and L3 may be the same or different.

[0070] In the antenna assembly of this disclosure, the other first tuning branches among a plurality of first tuning branches include a first inductor. The inductance values ​​of the first inductors on different first tuning branches can be the same or different, so that the first radiator can match the signal impedance of different frequency bands by connecting to different first tuning branches, thereby obtaining better radiation efficiency and performance.

[0071] In some embodiments of this disclosure, the second switching circuit includes a second switching component and a plurality of second tuning branches. The second switching component includes a plurality of sets of second switching switches connected in parallel with each other, and each second switching switch is connected in series with any second tuning branch.

[0072] like Figure 3 As shown, the second switching circuit 6 includes a second switching assembly 61, which includes four sets of second switching switches connected in parallel, namely second switching switches 611 to 614. The second switching circuit 6 also includes four second tuning branches, namely second tuning branches 62 to 65.

[0073] Specifically, the second switching switch 611 is connected in series with the second tuning branch 62, the second switching switch 612 is connected in series with the second tuning branch 63, the second switching switch 613 is connected in series with the second tuning branch 64, and the second switching switch 614 is connected in series with the second tuning branch 65.

[0074] In this embodiment of the disclosure, one of the plurality of second tuning branches includes a second capacitor and a second inductor connected in series, wherein when the second switching switch connected in series with the second tuning branch is switched to the on state, the second radiator is switched to the inductor state.

[0075] like Figure 3 As shown, the second tuning branch 62 includes a second capacitor C2 and a second inductor L4. When the second switching switch 611, which is connected in series with the second tuning branch 62, is turned on, the second tuning branch 62 (including the second capacitor C2 and the second inductor L4) is connected to the circuit.

[0076] In the antenna assembly of this disclosure, one of the plurality of second tuning branches includes a second capacitor and a second inductor. When the second tuning branch including the second capacitor and the second inductor is connected to the circuit, the second radiator exhibits an inductor-like effect electrically, that is, its impedance characteristics become similar to the impedance characteristics of an inductor at certain frequencies. In this case, the second radiator can be considered to be in an inductive state. This inductive effect improves the efficiency of the first radiator through electrical parasitic effects.

[0077] In some embodiments of this disclosure, the other second tuning branches besides one of the plurality of second tuning branches include a third capacitor. The capacitance values ​​of the third capacitors in different second tuning branches may be the same or different. When all second switching switches connected in series with the other second tuning branches are in the ON state, the second radiator switches to the second capacitor state.

[0078] like Figure 3 As shown, apart from the second tuning branch 62, the tuning elements in the other second tuning branches 63 to 65 are the third capacitors C3, C4, and C5, respectively. For example, the capacitance values ​​of the third capacitors C3, C4, and C5 may be the same or different.

[0079] When the second switching switch 612 connected in series with the second tuning branch 63, the second switching switch 613 connected in series with the second tuning branch 64, and the second switching switch 614 connected in series with the second tuning branch 65 are all turned on, the second tuning branch 63 (including the third capacitor C3), the second tuning branch 64 (including the third capacitor C4), and the second tuning branch 65 (including the third capacitor C5) are connected to the circuit. At this time, the capacitance value connected to the circuit is the maximum, and the second radiator is considered to have switched to the second capacitance state, that is, the maximum capacitance state.

[0080] In the antenna assembly of this disclosure embodiment, the other second tuning branches among the plurality of second tuning branches, excluding one second tuning branch, include a third capacitor. When all other second tuning branches are connected to the circuit, the impedance characteristics of the second radiator are similar to those of a capacitor at certain frequencies. In this case, the second radiator can be considered to be in a second capacitor state. Since the connected capacitance value is the largest, the second radiator can also be considered to be in a maximum capacitor state. This maximum capacitor effect improves the efficiency of the first radiator through electroparasitic effects.

[0081] In an exemplary embodiment, the first radiator 1 operates in the MHB band, and the second radiator 2 operates in the LB and N77 bands. A second switching circuit 6 is introduced at the second feed point 22 of the second radiator 2. The second switching circuit 6 includes second switching switches 611 to 614 and second tuning branches 62 to 65. Second switching switch 611 is connected in series with second tuning branch 62, second switching switch 612 is connected in series with second tuning branch 63, second switching switch 613 is connected in series with second tuning branch 64, and second switching switch 614 is connected in series with second tuning branch 65. Second tuning branch 62 includes a second capacitor C2 and a second inductor L4, and second tuning branches 63 to 65 each include a third capacitor C3, C4, and C5.

[0082] When the second radiator 2 operates in the LB band, if the second switching switch 611 is turned on, the second tuning branch 62, including the second capacitor C2 and the second inductor L4, is connected to the circuit. In this case, the second radiator 2 exhibits impedance characteristics similar to an inductor. This inductance characteristic introduces an electrical parasitic effect. The efficiency dip caused by this electrical parasitic effect can improve the efficiency of the first radiator 1 in the B40 band.

[0083] When the second radiator 2 operates in the LB band, if all of the second switching switches 612 to 614 are turned on, then the second tuning branch 63 (including the third capacitor C3), the second tuning branch 64 (including the third capacitor C4), and the second tuning branch 65 (including the third capacitor C5) are all connected to the circuit. In this case, the second radiator 2 exhibits impedance characteristics similar to those of a capacitor. This capacitance characteristic introduces an electrical parasitic effect, and the efficiency dip caused by this electrical parasitic effect can improve the efficiency of the first radiator 1 in the B3 band.

[0084] In some embodiments of this disclosure, the antenna assembly further includes a third inductor, one end of which is electrically connected between the first switching circuit and the tuning point, and the other end of which is grounded.

[0085] Figure 4 This is a structural diagram of another antenna assembly illustrated according to an exemplary embodiment of the present disclosure. Figure 4 As shown, the antenna assembly 100 also includes a third inductor 7, one end of which is electrically connected between the first switching circuit 5 and the tuning point 14, and the other end of which is grounded.

[0086] The antenna assembly of this embodiment adds a third inductor. One end of the third inductor is electrically connected between the first switching circuit and the tuning point, while the other end is directly grounded, so that the third inductor and the first switching circuit are connected in parallel. In this way, the first switching circuit can be omitted, and aperture tuning can be performed by relying on the third inductor. This provides the antenna assembly with a more flexible and efficient operating mode selection, effectively reduces the loss caused by the operation of the first switching circuit, and thus improves the overall performance of the antenna assembly.

[0087] In some embodiments of this disclosure, such as Figure 4 As shown, the antenna assembly 100 also includes a fourth capacitor 8 and a fifth capacitor 9. One end of the fourth capacitor 8 is electrically connected to the first feed point 12, and the other end of the fourth capacitor 8 is electrically connected to the first feed source 3. One end of the fifth capacitor 9 is electrically connected to the second feed point 22, and the other end of the fifth capacitor 9 is electrically connected to the second feed source 4.

[0088] The antenna assembly of this disclosure connects a fourth capacitor between the first feed point and the first feed source, and a fifth capacitor between the second feed point and the second feed source. This allows for adjustment of the antenna input impedance without altering the basic antenna structure, enabling the antenna input impedance to more flexibly match the characteristic impedance of the transmission line. Furthermore, by adjusting the capacitance values ​​of the fourth and fifth capacitors, the impedance characteristics of the antenna at different frequencies can be optimized, thereby reducing signal reflection loss during transmission and improving energy transmission efficiency.

[0089] An exemplary embodiment of this disclosure also provides an electronic device that may include the antenna assembly described above.

[0090] It should be noted that, for example, electronic devices can be mobile phones, tablets, e-readers, MP3 players, MP4 players, laptops, in-vehicle systems or desktop computers, portable terminals, laptop terminals, desktop terminals, action cameras, drones, monitor cameras, and similar products.

[0091] Figure 5 This is a schematic diagram illustrating the location of an antenna assembly in an electronic device according to an exemplary embodiment of this disclosure. Figure 5 As shown, the antenna assembly 100 can be disposed on the right side of the electronic device.

[0092] In this embodiment, the antenna assembly is positioned on the side of the electronic device, which allows for more efficient use of space and reduces interference from other parts of the electronic device (such as the metal frame or screen) on signal reception and transmission, maintaining good signal reception and transmission efficiency. Furthermore, positioning the antenna assembly on the right side facilitates operation and avoids signal problems caused by hands obstructing the antenna.

[0093] It should be noted that the electronic device in this embodiment can be a foldable electronic device or a flat-screen electronic device (non-foldable electronic device), and the antenna assembly can be located on any side of the electronic device.
