Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of electronic devices, and in particular, to an antenna assembly and an electronic device. BACKGROUND

[0002] With the development of electronic device technology, the internal design thereof is increasingly sophisticated. As one of the core components, the design of an antenna directly affects the communication performance and user experience of the electronic device. A GPS / WIFI antenna is usually arranged at a top corner region of the whole machine, and a ground return rib is arranged at the opposite side of the radiation arm to reduce mutual interference with other antennas.

[0003] In the related art, considering that the width of the ground return rib is affected by the length of the antenna itself and the distance of the upper frame, the width of the ground return rib is different in different antenna schemes. The related art adds an upper frame point next to the rib on the side close to the GPS / WIFI antenna, and sets a tuning circuit to tune the rib structure, which can reduce the requirement for the width of the rib to a certain extent.

[0004] However, due to the influence of the rib design stack, the scheme provided by the related art often cannot meet the optimal upper frame position. Moreover, since the tuning circuit itself has a certain performance loss, it will cause a loss of antenna performance. Therefore, there is an urgent need for an antenna design scheme that can avoid the design complexity of the ground return rib and the performance loss of the tuning circuit, and thus reduce the damage to the antenna performance.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0032] The present disclosure will be described hereinafter with reference to accompanying drawings, in which, as shown in the drawings: like reference numerals in different drawings denote like elements, and the following detailed description is exemplary and explanatory only and is not restrictive of the disclosure.

[0033] The implementations described below in some embodiments of the present disclosure are not meant to represent all implementations consistent with the present disclosure. Rather, they are examples only of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] The specific embodiments of the present disclosure will be described hereinafter with reference to the drawings, in which:

[0035] The specific embodiments of the present disclosure will be described hereinafter with reference to the drawings, in which:Figure 1 is a structural schematic diagram of an antenna assembly according to some embodiments of the present disclosure. As shown in Figure 1 the antenna assembly 100 includes a radiating branch 1 and a floating branch 2.

[0036] The radiating branch 1 is provided with a feed point 11. The floating branch 2 is coupled to the radiating branch 1 through a break 3, and the floating branch 2 is provided with a return point 21.

[0037] Exemplarily, the operating wavelength of the antenna assembly 100 includes a first wavelength and a second wavelength, where the first wavelength is greater than the second wavelength. The length of the radiating branch 1 is positively correlated with the first wavelength, and a first distance between the feed point 11 and an end of the radiating branch 1 close to the break 3 is positively correlated with the second wavelength.

[0038] In some exemplary embodiments, the antenna assembly 100 can be an antenna designed in the form of an IFA (Inverted-F Antenna).

[0039] Exemplarily, the radiating branch 1 is provided with the feed point 11. When current flows into the radiating branch 1 through the feed point 11, the radiating branch 1 is excited to radiate electromagnetic waves. As shown in Figure 1 the solid arrow can represent feeding to the radiating branch 1 through the feed point 11. In addition, the radiating branch 1 can also be coupled to the floating branch 2 through the break 3, so that the floating branch 2 can also be excited to radiate electromagnetic waves.

[0040] It should be noted that the feed point 11 provided on the radiating branch 1 and the return point 21 provided on the floating branch 2 can be understood as two upper frame points. Exemplarily, the upper frame position of the feed point 11 can be on the side of the radiating branch 1 close to the break 3, and the upper frame position of the return point 21 can be on the side of the floating branch 2 close to the break 3. As shown in Figure 1 the dotted arrow can represent grounding of the floating branch 2 through the return point 21.

[0041] Embodiments of the present disclosure can set the length of the radiating branch 1 according to the first wavelength, and set the upper frame position of the feed point 11 according to the second wavelength. Exemplarily, the length of the radiating branch 1 and the first wavelength can be in a multiple relationship, and the first distance and the second wavelength can be in a multiple relationship. The multiple may, for example, be one-half, one-fourth, one-eighth, etc.

[0042] The antenna assembly 100 provided by the embodiments of the present disclosure is provided with the floating branch 2 on the opposite side of the radiating branch 1, and the grounding point 21 is arranged on the floating branch 2, so that the circuit ground can be performed through the floating branch 2 to achieve the grounding effect. The embodiments of the present disclosure effectively reduce the design complexity of the grounding, and ensure the antenna performance of the antenna assembly 100.

[0043] In addition, it should be noted that, in the embodiments of the present disclosure, Figure 1 The right side of the floating branch 2 shown can be provided with other antenna branches in addition to the antenna assembly 100 provided by the present disclosure, and the embodiments of the present disclosure do not limit this. The circuit ground provided by the embodiments of the present disclosure by arranging the floating branch 2 can reduce the interference between the antenna assembly 100 and the above-mentioned other antenna branches.

[0044] In some exemplary embodiments, the first wavelength can be a GPS signal wavelength, and the second wavelength can be a WIFI signal wavelength. That is, the antenna assembly 100 can be a GPS / WIFI antenna. Moreover, the GPS signal wavelength is greater than the WIFI signal wavelength. In this embodiment, the length of the radiating branch 1 can be equal to one quarter of the GPS signal wavelength, and the first distance can be equal to one quarter of the WIFI signal wavelength. That is, the antenna assembly 100 can be a quarter wavelength antenna. Exemplarily, as shown in Figure 1 The length of the radiating branch 1 can be represented as X1. The first distance can be represented as X2.

[0045] In a possible implementation, the main working frequency of the GPS signal is L1 frequency band, that is, 1575.42 MHz. The GPS signal wavelength corresponding to the L1 frequency band is about 19 cm. Therefore, the length of the radiating branch 1 can be equal to one quarter of the GPS signal wavelength, about 4.75 cm. Similarly, the main working frequency of the WIFI signal includes 2.4 GHz and 5 GHz. Taking 5 GHz as an example, the WIFI signal wavelength at this time is about 6 cm. Therefore, the first distance is equal to one quarter of the WIFI signal wavelength, about 1.5 cm.

[0046] It should be noted that, by setting the length of the radiating branch 1 to be one quarter of the GPS signal wavelength and the first distance to be one quarter of the WIFI signal wavelength, the embodiments of the present disclosure can ensure the antenna performance while reducing the physical size of the radiating branch 1, thereby releasing the internal space of the electronic device and reducing the manufacturing cost.

[0047] It should be noted that, the antenna assembly 100 is designed as a quarter wavelength antenna, which is a preferred scheme. In other embodiments, the antenna assembly 100 can also be a half wavelength antenna, an eighth wavelength antenna, etc., and the embodiments of the present disclosure do not limit this.

[0048] In an exemplary embodiment, the antenna assembly 100 can be a half-wavelength antenna. Taking the L1 band as an example, where the primary operating frequency of the GPS signal is approximately 19 centimeters, the length of the radiating stub 1 can be equal to half the GPS signal wavelength, approximately 9.5 centimeters. Similarly, taking 5GHz as an example, where the primary operating frequency of the WIFI signal is approximately 6 centimeters, the first distance is equal to half the WIFI signal wavelength, approximately 3 centimeters.

[0049] In some exemplary embodiments, the length of the suspended stub 2 may be between the length of the radial stub 1 and the first distance.

[0050] In some possible implementations, the length of the radiating stub 1 can be equal to one-quarter of the GPS signal wavelength, and the first distance can be equal to one-quarter of the Wi-Fi signal wavelength. Therefore, the length of the levitated stub 2 can be between one-quarter of the Wi-Fi signal wavelength and one-quarter of the GPS signal wavelength. For example, as... Figure 1 As shown, the length of the suspended branch 2 can be represented as X3.

[0051] It should be noted that when the antenna assembly 100 is a quarter-wavelength antenna, the length of the suspended stub 2 can also be defined as being within the range of a quarter of the first wavelength to a quarter of the second wavelength.

[0052] For example, when the length of the suspended stub 2 is equal to one-quarter of the GPS signal wavelength, a current in the suspended stub 2 flows in the same direction as the radiating stub 1 in the GPS band. Similarly, when the length of the suspended stub 2 is equal to one-quarter of the WIFI signal wavelength, a current in the suspended stub 2 flows in the same direction as the radiating stub 1 in the WIFI band. Therefore, when the length of the suspended stub 2 is between one-quarter of the WIFI signal wavelength and one-quarter of the GPS signal wavelength, a current pattern between the two can exist on the suspended stub 2. Thus, by setting the length of the suspended stub 2, the suspended stub 2 can simultaneously have a current in the same direction as the radiating stub 1 in both the GPS and WIFI bands. Therefore, the embodiments of this disclosure can improve the radiation efficiency of the radiating stub 1 in both the GPS and WIFI bands, thereby improving antenna performance.

[0053] In some exemplary embodiments, the second distance between the return point 21 and the end of the suspended branch 2 near the fracture 3 is less than the first distance.

[0054] For example, such as Figure 1 As shown, the second distance can be represented as X4.

[0055] In some possible implementations, the first distance can be equal to one-quarter of the Wi-Fi signal wavelength. In this embodiment, when the second distance is not less than one-quarter of the Wi-Fi signal wavelength, the inefficient mode of the dangling stub 2 will fall within the Wi-Fi signal frequency band, thus affecting antenna performance. However, when the second distance is less than one-quarter of the Wi-Fi signal wavelength, the frequency of the inefficient mode of the dangling stub 2 is higher than the Wi-Fi signal frequency, and the inefficient mode falls outside the Wi-Fi signal frequency band, thereby reducing the impact on antenna performance. Therefore, by setting the upper frame position of the return point 21, the embodiment of this disclosure can effectively avoid the influence of the inefficient mode of the dangling stub 2, thereby ensuring antenna performance.

[0056] It should be noted that when the antenna assembly 100 is a quarter-wavelength antenna, the length of the second distance can also be defined as less than a quarter of the second wavelength.

[0057] In some exemplary embodiments, the current direction on the radiating stub 1 is the same as the current direction on the suspended stub 2.

[0058] In some embodiments, when the length of the radiating stub 1 is one-quarter of the GPS signal wavelength and the first distance is one-quarter of the WIFI signal wavelength, and the length of the suspended stub 2 is between one-quarter of the WIFI signal wavelength and one-quarter of the GPS signal wavelength, and the second distance is not less than one-quarter of the WIFI signal wavelength, then the current on the suspended stub 2 can be in the same direction as the current on the radiating stub 1.

[0059] For example, a schematic diagram of the current direction of an antenna assembly provided in this disclosure embodiment can be as follows: Figure 2 As shown. In this Figure 2 In the diagram, the current direction of radiating stub 1 and the current direction of suspended stub 2 are both to the left. It should be noted that the antenna assembly provided in this embodiment can increase the signal radiation aperture and thus improve antenna performance by setting the current directions of radiating stub 1 and suspended stub 2 to be the same.

[0060] In some exemplary embodiments, the antenna assembly 100 may further include: a rib structure 4.

[0061] For example, the rib structure 4 can be electrically connected to the end of the radial branch 1 away from the fracture 3, and the radial branch 1 can be grounded through the rib structure 4.

[0062] In an exemplary embodiment, such as Figure 1 As shown, the upper end of the rib structure 4 can be electrically connected to the left end of the radial arm. Furthermore, the lower end of the rib structure 4 can be electrically connected to the ground plane 5, thus allowing the radial branch 1 to return to the ground via the rib structure 4.

[0063] It should be noted that the rib structure 4 can be a reinforcing structure or support designed on the metal frame or casing of the electronic device. Besides providing grounding for the ribs of the radial branches, the rib structure 4 can also enhance the mechanical strength of the electronic device to prevent deformation. Furthermore, this disclosure does not limit the length or width of the rib structure 4.

[0064] In an exemplary embodiment, the antenna assembly 100 may further include a ground plane 5.

[0065] In some possible implementations, the ground plane 5 can be understood as a large-area conductor in an electronic device, used to provide a stable reference potential and participate in signal transmission as part of the radiation of the antenna assembly 100.

[0066] It should be noted that, in this embodiment of the present disclosure, the rib structure 4 can be used to realize the rib return to ground of the radiating branch 1 to form a low impedance loop. The rib return to ground design can effectively ensure the radiation efficiency of the antenna assembly 100 and can shield external interference signals, reducing the impact of internal circuits on the antenna assembly 100.

[0067] In some exemplary embodiments, the suspended stub 2 can be grounded via a target element 22 electrically connected to the return point 21.

[0068] In an exemplary embodiment, the target element 22 may be included in the grounding circuit of the suspended stub 2. The suspended stub 2 can replace the rib-based grounding design in related technologies with a circuit-based grounding, fundamentally avoiding problems such as the complexity of rib width design and improving antenna performance.

[0069] In some other exemplary embodiments, the target element 22 can be a capacitor with a capacitance value greater than a preset value, so that the suspended stub 2 is in an open circuit state relative to the ratio absorption rate signal.

[0070] For example, a schematic diagram of the structure of an antenna assembly provided in this disclosure embodiment can be as follows: Figure 3 As shown, the target element 22 is a capacitor element with a capacitance value greater than a preset value. At this time, the suspended stub 2 can be regarded as a SAR (Specific Absorption Rate) sensing stub.

[0071] In an exemplary embodiment, the suspended stub 2 can be used to sense SAR values ​​to reduce the power of GPS signals and WIFI signals, thereby reducing the SAR value of the antenna assembly 100.

[0072] It should be noted that the embodiments disclosed herein do not limit the preset value. For example, the preset value can be an empirical value or can be set according to the SAR control chip. For example, the preset value can be 20pF, 30pF, etc.

[0073] In some exemplary embodiments, the relationship between the impedance of the capacitor element and the operating frequency can be represented by the following formula (1).

[0074]

[0075] In formula (1), Z C Z represents the impedance of the capacitor, ω represents the angular frequency, f represents the operating frequency, and C represents the capacitance. It can be seen that the higher the operating frequency f, the higher the impedance Z of the capacitor. C The smaller.

[0076] For example, when the antenna assembly 100 is a GPS / WIFI antenna, the GPS signal belongs to the UHF range, while the WIFI signal belongs to the UHF and EHF ranges. Therefore, the capacitor element provided here has extremely low high-frequency impedance for the frequency bands of GPS and WIFI signals, and has little obstruction to current. It can be regarded as a short circuit for the frequency bands of GPS and WIFI signals. At this time, the levitated stub 2 is grounded due to the short circuit.

[0077] As for the specific absorption rate signal, it is mainly used to sample low-frequency signals. The capacitor element will block DC, so the levitated stub 2 can be regarded as having an open circuit state for the specific absorption rate signal. That is, at this time, the branch where the antenna component 100 is located is equivalent to a closed circuit, while the branch where the SAR control chip is located is equivalent to an open circuit.

[0078] The embodiments disclosed herein, through the setting of capacitor elements, not only can the circuit of the suspended stub 2 be grounded, thereby reducing the complexity of the antenna grounding design and improving the antenna performance, but also the DC blocking effect can be achieved through capacitor elements, so that the suspended stub 2 can also serve as a SAR sensing stub and realize the SAR reduction function.

[0079] In some exemplary embodiments, the target element 22 may be a wire.

[0080] In this case, the return point 21 can be electrically connected to the ground plane 5 via a wire, thereby enabling the suspended stub 2 to return to the ground via a circuit.

[0081] It should be noted that the present disclosure does not limit the target element 22. In addition to being a capacitor or a wire, the target element 22 can also be an inductor, a resistor, etc.

[0082] Figure 4This is a performance schematic diagram of an antenna assembly according to some embodiments of this disclosure. For example... Figure 4 As shown, the horizontal axis represents frequency in gigahertz (GHz), and the vertical axis represents decibels (dB).

[0083] The antenna efficiency of the antenna assembly provided in this disclosure can be represented by a system radiation efficiency curve and a system total efficiency curve. Figure 4 In the diagram, the upper curve represents the system's radiation efficiency curve, and the lower curve represents the system's overall efficiency curve. Figure 4 Point A (1.575, -1.615107) indicates that the system radiation efficiency at a frequency of 1.575 GHz is -1.615107 dB. That is, the peak efficiency of the levitated stub 2 in the antenna assembly 100 in the GPS signal L1 band is -1.615107 dB. Additionally, point B (2.45, -1.203351) indicates that the system radiation efficiency at a frequency of 2.45 GHz is approximately -1.203351 dB. That is, the peak efficiency of the levitated stub 2 in the antenna assembly 100 in the WIFI signal 2.4 GHz band is -1.203351 dB.

[0084] Therefore, according to Figure 4 As can be seen, the antenna assembly provided in this embodiment can ensure the excellent performance of the antenna.
