[0002] With the continuous development of electronic design, users' demands for electronic devices are also constantly increasing. These demands typically include various usage scenarios, such as holding the device horizontally or vertically. To ensure a good online experience, it's essential to ensure that the antenna components within electronic devices can adapt to these different usage scenarios.

[0003] In related technologies, antennas such as Wi-Fi (wireless fidelity) antennas can be placed at the top rounded corner of an electronic device to ensure that the antenna radiates signals into the sky when the user holds the device vertically. However, this design results in the user gripping the device horizontally, which can lock the antenna in place, affecting antenna performance and reducing the user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0036] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0037] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0039] Figure 1 This is a schematic diagram illustrating the structure of an antenna assembly according to an exemplary embodiment of this disclosure. Figure 1 As shown, the antenna assembly 100 may include: a first antenna 1, a first matching circuit 11, a second antenna 2, a first capacitor 21, and a first feed terminal 31.

[0040] The first antenna 1 can be electrically connected to the first feed terminal 31 via the first matching circuit 11. The second antenna 2 can be electrically connected to the first feed terminal 31 via the first capacitor 21. The first feed terminal 31 is used to feed power to the first antenna 1 and the second antenna 2 so that the first antenna 1 and the second antenna 2 support the first operating frequency band.

[0041] This disclosure does not limit the type of the first antenna 1. For example, the first antenna can be a half-wavelength antenna, a quarter-wavelength antenna, an eighth-wavelength antenna, etc. The first feed terminal 31 can feed the first antenna 1, so the first antenna 1 can radiate signals for the first operating frequency band. Furthermore, the first feed terminal 31 can also feed the second antenna 2, so the second antenna 2 can also radiate signals for the first operating frequency band.

[0042] This disclosure does not limit the first operating frequency band. For example, the first operating frequency band can be a WIFI band, a GPS (Global Positioning System) band, a Bluetooth band, a cellular band, etc.

[0043] It should be noted that both the first antenna 1 and the second antenna 2 can independently radiate signals in the first operating frequency band. Therefore, in some application scenarios, if the performance of the first antenna 1 is reduced due to reasons such as being held tightly, the second antenna 2 can radiate independently, thereby effectively increasing the signal radiation surface of the antenna assembly 100 and improving the antenna performance.

[0044] In an exemplary embodiment, the first antenna 1 can be a frame antenna, and the second antenna 2 can be an LDS antenna. Exemplarily, the LDS antenna can be a monopole antenna.

[0045] In this case, since the frame antenna may be gripped tightly in a landscape hand-held scenario, while the LDS antenna can be placed in a position in the electronic device that will not be gripped tightly in a landscape hand-held scenario, the embodiments of this disclosure can effectively increase the radiation surface of the antenna, thereby improving the user experience.

[0046] In an exemplary embodiment, the first antenna 1 can achieve impedance matching based on the first matching circuit 11 to ensure that the input impedance of the first antenna 1 matches the characteristic impedance of the first feed terminal 31. Furthermore, the second antenna 2 can achieve impedance matching based on the first capacitor 21. This embodiment does not limit the value of the characteristic impedance of the feed source; for example, the characteristic impedance can be 50 ohms, 75 ohms, etc.

[0047] In some exemplary embodiments, the capacitance value of the first capacitor 21 is negatively correlated with the equivalent inductive reactance of the second antenna 2 and / or the operating frequency of the second antenna 2.

[0048] For example, the capacitance value of the first capacitor 21 can be calculated according to the following formula (1).

[0049]

[0050] In formula (1), C can represent the capacitance value of the first capacitor 21. f can represent the operating frequency of the second antenna 2. L It can represent the equivalent resistance value of Line 2 on the second day.

[0051] In an exemplary embodiment, X may be assumed L =40. Taking the 2.4G standard with the first working frequency band as the WIFI band as an example, f = 2.4GHz. Therefore, according to the above formula (1), the capacitance value of the first capacitor 21 can be calculated to be approximately 1.66pF. Or, taking the 5G standard with the first working frequency band as the WIFI band as an example, f = 5GHz. Therefore, according to the above formula (1), the capacitance value of the first capacitor 21 can be calculated to be approximately 0.69pF.

[0052] It should be noted that the capacitance value of the first capacitor 21 can be determined by the equivalent inductive reactance of the second antenna 2 and the operating frequency, so that the inductive reactance can be canceled by the first capacitor 21, thereby achieving impedance matching.

[0053] In some exemplary embodiments, an antenna assembly 100 provided in this disclosure may further include: a first SAR chip 22, which is electrically connected between the first capacitor 21 and the first feed terminal 31.

[0054] In this case, the first capacitor 21 can also be used to isolate low-frequency signals. Furthermore, the second antenna 2 can be a monopole antenna, thus having no other ground loops on it, and can therefore be considered a floating stub. Therefore, the second antenna 2 can serve as a SAR sensing stub to achieve SAR reduction.

[0055] In an exemplary embodiment, the first matching circuit 11 can be determined based on a first operating frequency band. Taking the WIFI frequency band as an example, Figure 2 A schematic diagram of the structure of an antenna assembly provided in an embodiment of this disclosure is shown.

[0056] In Figure 2 In this circuit, the first matching circuit 11 may include: a third capacitor 111, a fourth capacitor 112, and a first inductor 113. The first antenna 1 may be electrically connected to the first terminal of the third capacitor 111, the second terminal of the third capacitor 111 may be electrically connected to the first terminal of the first inductor 113, the second terminal of the first inductor 113 may be electrically connected to the first feed terminal 31, and the fourth capacitor 112 may be electrically connected between the second terminal of the first inductor 113 and the first feed terminal 31.

[0057] like Figure 2 As shown, the first end of the third capacitor 111 can be the left end of the third capacitor 111, and the second end of the third capacitor 111 can be the right end of the third capacitor 111. Similarly, the first end of the first inductor 113 can be the left end of the first inductor 113, and the second end of the first inductor 113 can be the right end of the first inductor 113. Furthermore, the upper end of the fourth capacitor can be electrically connected between the second end of the first inductor 113 and the first feed terminal 31, while the lower end of the fourth capacitor can be used for grounding.

[0058] In one possible implementation, the capacitance of the third capacitor 111 can be 1.7pF, the capacitance of the fourth capacitor 112 can be 0.2pF, and the inductance of the first inductor 113 can be 2.7nH.

[0059] It should be noted that the structure of the first matching circuit 11 only needs to satisfy the impedance matching of the first operating frequency band. The structure of the first matching circuit 11 described above is merely an example and is not intended to limit this disclosure. For example, another schematic diagram of the antenna assembly provided in the embodiments of this disclosure can be as follows: Figure 3 As shown.

[0060] It can be seen that, Figure 3 The first matching circuit 11 shown is with Figure 2 The first matching circuit 11 shown in the diagram is different. Figure 3 Will Figure 2 The third capacitor 111, with a capacitance of 1.7pF, was replaced with two capacitors with a capacitance of 0.3pF each.

[0061] In some possible implementations, the first feed terminal 31 can be an RF socket. The RF socket is electrically connected between the first matching circuit 11 and the corresponding RF back-end, which can be regarded as a signal processing unit to perform amplification, filtering, modulation or demodulation of the first operating frequency band signal radiated by the first antenna 1.

[0062] It should be noted that the antenna assembly 100 provided in this embodiment can achieve the independence of the second antenna 2 and the first antenna 1 by setting the first capacitor 21, thus avoiding the impact on the equivalent electrical length of the second antenna 2 when the first antenna 1 is clamped. Since the change in the equivalent electrical length of the second antenna 2 will cause waveform frequency offset, resulting in a negative impact on the second antenna 2, this embodiment can improve the antenna performance of the second antenna 2.

[0063] Furthermore, the embodiments disclosed herein achieve an integrated design of the first antenna 1 and the second antenna 2. The first antenna 1 and the second antenna 2 can be connected to the same RF socket without the need for an additional RF combiner, thus minimizing link insertion loss and further improving antenna performance.

[0064] In some exemplary embodiments, an antenna assembly 100 provided in this disclosure may further include a second matching circuit 12 and a second feed terminal 32.

[0065] The first antenna 1 can be electrically connected to the second feed terminal 32 through the second matching circuit 12. The second feed terminal 32 is used to feed the first antenna 1 so that the first antenna 1 supports the second operating frequency band.

[0066] This disclosure does not limit the second operating frequency band. For example, the second operating frequency band can be a WIFI band, GPS band, Bluetooth band, cellular band, etc., and the second operating frequency band can be different from the first operating frequency band.

[0067] For example, Figure 4This is a schematic diagram illustrating the structure of another antenna assembly according to an exemplary embodiment of the present disclosure. Figure 4 In this context, the first antenna 1 can support both the first and second operating frequency bands.

[0068] In one possible embodiment, the first operating frequency band can be a Wi-Fi band, and the second operating frequency band can be a GPS band. In this case, the Wi-Fi band and the GPS band can share the first antenna 1, that is, the Wi-Fi antenna and the GPS antenna share an antenna stub. When the first antenna 1 is a frame antenna, it may be locked in a landscape handheld scenario, but this will not affect the antenna performance of the second antenna 2.

[0069] The second feed terminal 32 can be an RF socket. The RF socket is electrically connected between the second matching circuit 12 and the corresponding RF back-end. The RF back-end connected to the second matching circuit 12 can be regarded as a signal processing unit, thereby realizing the amplification, filtering, modulation or demodulation of the second operating frequency band signal radiated by the first antenna 1.

[0070] This disclosure does not limit the second matching circuit 12, which can be determined based on the second operating frequency band. Figure 4 For example, the second matching circuit 12 may include: a fifth capacitor 121, a sixth capacitor 122, a second inductor 123, and a third inductor 124.

[0071] The first antenna 1 can be electrically connected to the left end of the fifth capacitor 121, which is also electrically connected to the upper end of the second inductor 123. The lower end of the second inductor 123 is used for grounding. The right end of the fifth capacitor 121 is electrically connected to the left end of the third inductor 124, which is also electrically connected to the second feed terminal 32. The right end of the third inductor 124 can also be electrically connected to the upper end of the sixth capacitor 122, which is used for grounding.

[0072] In an exemplary embodiment, the second antenna 2 can be used as a SAR sensing stub to perform SAR sensing on the second operating frequency band, thereby achieving SAR reduction and reducing the impact of SAR on the antenna performance of the second operating frequency band.

[0073] In some exemplary embodiments, an antenna assembly 100 provided in this disclosure may further include a third antenna 4.

[0074] The third antenna 4 is electrically connected to the second feed terminal 32 via the second capacitor 41. The second feed terminal 32 is also used to feed power to the third antenna 4 so that the third antenna 4 supports the second operating frequency band.

[0075] For example, Figure 5This is a schematic diagram illustrating the structure of another antenna assembly according to an exemplary embodiment of the present disclosure. Figure 5 In this configuration, the first antenna 1 can support both the first and second operating frequency bands, the second antenna 2 can support the first operating frequency band, and the third antenna 4 can support the second operating frequency band.

[0076] In an exemplary embodiment, the first antenna 1 can be a frame antenna, and the second antenna 2 and the third antenna 4 can be LDS antennas. Exemplarily, the LDS antenna can be a monopole antenna.

[0077] In this case, since the bezel antenna may be locked in a landscape grip scenario, while the LDS antenna can be placed in a position in the electronic device that will not be locked in a landscape grip scenario, the second antenna 2 can ensure the antenna performance of the first operating frequency band in a landscape grip scenario, and the third antenna 4 can ensure the antenna performance of the second operating frequency band in a landscape grip scenario, thereby improving the user experience.

[0078] In an exemplary embodiment, the third antenna 4 can achieve impedance matching based on the second capacitor 41. In some exemplary embodiments, the capacitance value of the second capacitor 41 is negatively correlated with the equivalent inductive reactance of the third antenna 4 and / or the operating frequency of the third antenna 4.

[0079] For example, the capacitance value of the second capacitor 41 can be calculated according to formula (1).

[0080] Where C represents the capacitance value of the second capacitor 41, and f represents the operating frequency of the third antenna 4. L This can represent the equivalent inductive reactance of the third antenna 4. The capacitance value of the second capacitor 41 can be calculated in the same way as the capacitance value of the first capacitor 21, and will not be repeated here.

[0081] In some exemplary embodiments, an antenna assembly 100 provided in this disclosure may further include a second SAR chip 42, which is electrically connected between the second capacitor 41 and the second feed terminal 32.

[0082] In this case, the second capacitor 41 can also be used to isolate low-frequency signals. Furthermore, the third antenna 4 can be a monopole antenna, thus having no other ground loops and can be considered a floating stub. Therefore, the third antenna 4 can also serve as a SAR sensing stub to achieve SAR reduction.

[0083] An exemplary embodiment of this disclosure also provides an electronic device that may include the antenna assembly described above.

[0084] For example, the first antenna 1 and the second antenna 2 can be positioned in different locations within the electronic device. Figure 6 As shown, Figure 6 A schematic diagram of the structure of an electronic device provided in an embodiment of this disclosure is shown.

[0085] In Figure 6 In this configuration, the first antenna 1 is mounted on the frame of the electronic device 200, and the second antenna 2 is mounted on the rear cover of the electronic device 200 and on the internal reinforcing bracket. The second antenna 2 can be an LDS patch antenna.

[0086] In an exemplary embodiment, the second antenna 2 is disposed on the rear cover and internal reinforcing bracket of the electronic device 200, that is, on the rear structure of the electronic device 200. It should be noted that the rear structure can be located on the back or rear shell of the electronic device, and the rear structure can be made of materials such as plastic.

[0087] In some exemplary embodiments, the third antenna 4 may also be an LDS patch antenna and disposed on the rear cover of the electronic device 200 and the internal reinforcement bracket of the device. Exemplarily, the third antenna 4 may be disposed on the left or right side of the second antenna 2, etc., and this disclosure does not limit this.

[0088] The embodiments disclosed herein employ a frame + back cover LDS patch antenna scheme to improve the omnidirectionality of the antenna assembly 100 and ensure its antenna performance, thereby effectively enhancing the user experience.

[0089] It should be noted that, by way of example, the electronic device can be a mobile phone, tablet computer, e-reader, MP3 player, MP4 player, laptop computer, in-vehicle system or desktop computer, portable terminal, laptop terminal, desktop terminal, action camera, drone, monitor camera, and similar products. Furthermore, the electronic device in this embodiment can be a foldable electronic device or a flat-screen electronic device (non-foldable electronic device), and this embodiment does not impose any limitations on this.

[0090] Of course, in practical applications, the position of the antenna assembly can be flexibly adjusted according to factors such as the specific shape, size, internal structure and antenna performance requirements of the electronic device, and this disclosure does not limit this.

[0091] Figure 7 This is a performance schematic diagram of an antenna assembly according to some embodiments of this disclosure. For example... Figure 7 As shown, the horizontal axis represents the operating frequency, in MHz. The vertical axis represents EFF (Efficiency), in dB.

[0092] according to Figure 7As can be seen, the antenna efficiency of antenna assembly 100 is high and remains stable in both the low-frequency band (4500MHz to 5600MHz) and the mid-frequency band (5600MHz to 6300MHz). Therefore, this antenna assembly 100 can improve antenna performance and enhance the user experience.
