[0034] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0035] With the development of communication technology, the use scenarios of electronic devices are gradually increasing. To optimize the user experience and protect and extend the service life of electronic devices, users often use some accessories. However, these accessories may cause the antenna signal quality of electronic devices to degrade, thus seriously affecting the user experience.

[0036] For example, when the electronic device disclosed in the present invention is a tablet computer (PAD), a Deco (camera decoration) hidden FPC antenna can be provided on the PAD. The Deco hidden FPC antenna can be an antenna provided on the camera. Since it is blocked by Deco and not exposed to the outside, it can be called a hidden FPC antenna.

[0037] Deco hidden FPC antennas are increasingly being used in tablets and other devices due to their low cost, ease of fabrication, and high performance. However, PADs are often equipped with keyboard covers to optimize the user experience and extend the life of the device. However, surrounding the antenna with other media can affect the performance of Deco hidden FPC antennas, significantly reducing antenna efficiency and signal quality, which can severely impact the user experience. Therefore, a new signal-boosting cover system is urgently needed to enhance the user experience while also improving signal strength.

[0038] To overcome the problems existing in the related art, the present disclosure provides an accessory and an electronic device.

[0039] According to one aspect of an embodiment of the present disclosure, an accessory is provided, including: a shell, provided with an opening exposing a camera, a portion of the shell located on the peripheral side of the opening being provided with a first radiator, the first radiator being configured to couple with an antenna provided on a camera decorative part, and a current direction of the first radiator being consistent with a current direction of the antenna, wherein, in the thickness direction of the accessory, the shortest distance between the first radiator and the antenna is less than one eighth of the wavelength of the radiation frequency band of the antenna.

[0040] The disclosed accessory is provided with a first radiator, which can be electrically coupled to an antenna mounted on a camera of an electronic device, exciting a half-wavelength resonance on the first radiator. The current directions of the two currents are aligned, resulting in positive superposition, broadening the antenna's bandwidth and improving efficiency. The height difference between the first radiator and the antenna mounted on the camera of the electronic device can be less than one-eighth of the wavelength of the antenna's radiation frequency band. Therefore, when the disclosed accessory is placed on the light-entering side of the camera of an electronic device, it can enhance the antenna's signal while achieving the accessory's related functions, thereby improving the user experience.

[0041] The electronic devices involved in the present disclosure may also be referred to as terminal devices, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc., and are devices that provide voice and / or data connectivity to users. For example, the terminal may be a handheld device with wireless connection capabilities, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptop computers, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0042] In the present disclosure, an electronic device may be a terminal device, for example, a PAD. In the present disclosure, a camera of an electronic device may be a rear camera of the electronic device. An antenna provided on a camera decorative piece may be an FPC antenna or another type of antenna, as long as it is provided on the camera decorative piece and obscured by the Deco.

[0043] The accessories disclosed herein may be any accessories for being set on an electronic device, for example, an additional lens, a bracket, a back cover, a radiator, an external mobile power supply, an accessory for a wearable electronic device (for example, a watch strap), an external keyboard, a protective cover, a keyboard protective cover, etc.

[0044] Figure 1 It is a schematic structural diagram of an accessory according to an exemplary embodiment. Figure 2 The figure is a schematic structural diagram showing an accessory installed in an electronic device according to an exemplary embodiment. Figure 2 Yes Figure 1 The accessory 20 is shown as being installed on an electronic device. Figure 2 The perspective of FIG. 2 is a top-down perspective view, looking from one side of the accessory 20 to one side of the electronic device.

[0045] like Figure 1 and Figure 2 As shown, the accessory 20 of the present disclosure can be a protective cover or a keyboard protective cover, which can be set on the light incident side of the camera 50 of the electronic device. Generally, the accessory 20 can be set on the light incident side of the rear camera 50 of the electronic device, that is, on the back shell of the electronic device. Figure 1As shown, when the accessory 20 is a keyboard cover, it may include a mounting side 21 and a keyboard side 22 connected to each other. The mounting side 21 may be mounted on the rear housing of the electronic device, and the keyboard side 22 may be provided with a keyboard.

[0046] In some embodiments, accessory 20 may also be a protective case. In such an embodiment, the aforementioned mounting side 21 may be mounted on the rear housing of the electronic device, and the aforementioned keyboard side 22 may be a protective case folded into a shape such as a stand. It should be noted that the present disclosure is not limited thereto, and accessory 20 may be any of the aforementioned accessories.

[0047] In this disclosure, Figure 1 and Figure 2 As shown, the accessory 20 may include a housing 10, and the housing 10 is provided with an opening 300, through which the camera 50 may be exposed. A portion of the housing 10 located around the opening 300 may be provided with a first radiator 100. Figure 2 As shown, the first radiator 100 may be located on the first side 101 of the housing 10. The first radiator 100 may be a conductor such as metal.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the first radiator 100 may be located on a side of the opening 300 close to an edge of the housing 10 . For example, the first radiator 100 may be located on the first side 101 of the housing 10 .

[0049] In the present disclosure, the first radiator 100 may be located on one side of the opening 300 close to the top edge of the housing 10. Figure 2 and Figure 2 As shown, first side 101 can be one side of the top edge of housing 10. When accessory 20 is mounted on an electronic device, first side 101 can correspond to the top edge of the electronic device. It should be noted that the top portion here refers to the top portion of an electronic device as generally defined in the art, for example, it can be the portion near the motherboard. The first radiator 100 is disposed at the top edge of accessory 20, thereby enhancing the radiation performance of the electronic device towards the top edge.

[0050] Figure 4 The figure is a schematic diagram showing current distribution of an antenna of an electronic device according to an exemplary embodiment. Figure 5 The figure is a schematic diagram showing current distribution of a first radiator of an accessory according to an exemplary embodiment.

[0051] like Figure 4 and Figure 5As shown, when the accessory 20 is installed in the electronic device for use, the first radiator 100 can be configured to couple (for example, electrically couple) with the antenna 30 provided on the camera decoration 40, thereby exciting a half-wavelength resonance on the first radiator 100. Figure 4 and Figure 5 As shown, the current direction of the first radiator 100 is consistent with the current direction of the antenna 30, both flowing in the opposite direction of the X direction. The current direction of the first radiator 100 is consistent with the current direction of the antenna 30, resulting in positive superposition, which can broaden the bandwidth of the antenna 30 and improve efficiency.

[0052] When the accessory 20 is installed in an electronic device, there is a height difference between the accessory 20 and the antenna 30 in the thickness direction of the accessory 20 (that is, the thickness direction of the electronic device). For example, the shortest distance between the first radiator 100 and the antenna 30 is less than or equal to one-eighth of the wavelength of the radiation frequency band of the antenna 30. When the accessory of the present disclosure is installed on the light-entering side of the camera of an electronic device, it can enhance the antenna signal while realizing the relevant functions of the accessory, thus improving the user experience.

[0053] Generally, since the radiation direction of the FPC antenna of the electronic device is towards the back cover, the height of the first radiator 100 is higher than the height of the antenna 30, and the distance between the first radiator 100 and the antenna 30 is less than or equal to one eighth of the wavelength. Within this range, the farther the first radiator 100 is from the antenna 30 (that is, the greater the height difference between the two), the wider the bandwidth of the improved radiation efficiency, and the bandwidth can be flexibly adjusted according to the bandwidth requirements of the specific antenna.

[0054] In the present disclosure, the radiation frequency band of the antenna 30 may be around 2.5 GHz. It should be noted that this is only an example, and the accessory 20 of the present disclosure may be used in other electronic devices with antennas that radiate any frequency band.

[0055] In some embodiments, the shortest distance (height difference) between the first radiator 100 and the antenna 30 in the thickness direction of the accessory 20 may be 1-2 mm. For example, the shortest distance between the first radiator 100 and the antenna 30 may be 1.2-1.5 mm. For example, the shortest distance (height difference) between the first radiator 100 and the antenna 30 may be approximately 1.47 mm.

[0056] In some embodiments, as Figure 3As shown, the length of the first radiator 100 in the X direction can be less than or equal to one-quarter of the wavelength of the radiation frequency band of the antenna 30. For example, in some embodiments, the length of the first radiator in the X direction can be 20-50 mm. For example, in some embodiments, the length of the first radiator in the X direction can be 30-40 mm. For example, in some embodiments, the length of the first radiator in the X direction can be approximately 35.1 mm.

[0057] In the present disclosure, the opening may be a rectangular shape with rounded corners, e.g. Figure 3 In this case, the length of the first radiator 100 does not strictly refer to the length in the X direction, but the first radiator 100 extends in the X direction as a whole, and the overall length of the extension is the length in the X direction.

[0058] like Figure 3 As shown, the length of the first radiator 100 may be the sum of the length L11 of the central straight portion and the lengths L12 and L13 of the rounded portions on both sides. The length L11 of the central straight portion may be approximately 21.7 mm, the length L12 of the rounded portions on both sides may be approximately 6.7 mm, and the length L13 of the rounded portions on both sides may be approximately 6.7 mm.

[0059] In some embodiments, as Figure 3 As shown, the minimum distance W between the first radiator 100 and the antenna 30 in a plan view is 6-9 mm. For example, the minimum distance W between the first radiator 100 and the antenna 30 in a plan view is 7-8 mm. For example, the minimum distance W between the first radiator 100 and the antenna 30 in a plan view is about 7.95 mm.

[0060] In the plan view, the closer the distance between the first radiator 100 and the antenna 30 is, the higher the coupling strength is. However, the stronger the coupling is, the narrower the bandwidth of the entire system antenna is. In actual application, the specific implementation distance should be set according to the required bandwidth.

[0061] Table 1 shows the peak radiation efficiency and the peak total efficiency of the antenna 30 when the minimum distance W between the first radiator 100 and the antenna 30 in a plan view is different.

[0062] Table 1

[0063] Radiation efficiency Total efficiency PEAK PEAK The minimum distance W is 7.95mm -4.1 -4.3 The minimum distance W is 9.9mm -3.1 -3.7 The minimum distance W is 7.95mm -3.2 -3.8

[0064] In some embodiments, as Figure 2 and Figure 3As shown, a portion of the housing surrounding the opening can be a second radiator 200, with at least a portion of the second radiator 200 positioned opposite the first radiator 100. The second radiator 200 is configured to be electrically coupled to the antenna. A portion of the housing 10 surrounding the opening 300 can be configured as the first radiator 100. The second radiator 200 can be a conductor such as metal.

[0065] Figure 6 FIG. 1 is a schematic diagram showing the current distribution of a second radiator of an accessory according to an exemplary embodiment. Figure 6 As shown, when the accessory 20 is installed on an electronic device for use, the second radiator 200 can be configured to be electrically coupled with the antenna 30 provided on the camera decorative part 40, and the second radiator 200 can act as a signal reflector to enhance the signal of the antenna 30, thereby improving the radiation efficiency of the antenna 30.

[0066] In some embodiments, the length of the second radiator 200 may be greater than three quarters of the wavelength of the radiation frequency band of the antenna 30 .

[0067] For example, in some embodiments, the length of the second radiator 200 is 45-55 mm. For example, the length of the second radiator 200 is 50-53 mm. For example, the length of the second radiator 200 is approximately 52.8 mm. It should be noted that the length of the second radiator 200 described herein refers to the overall length of the second radiator 200 and is not limited to the direction in which it extends.

[0068] In some embodiments, the entire second radiator 200 may be disposed opposite to the first radiator 100. However, the present disclosure is not limited thereto, as long as the length requirement of the second radiator 200 is met.

[0069] However, the present disclosure is not limited thereto, and in some embodiments, the second radiator 200 may include a plurality of portions extending in different directions. Figure 3 As shown, the second radiator 200 may include a first portion 201 and a second portion 202 connected to each other, and the first portion 201 is disposed opposite to the first radiator 100 .

[0070] In some embodiments, as Figure 3 As shown, the second portion 202 may be located between the first portion 201 and the first radiator 100. However, the present disclosure is not limited thereto. In some embodiments, the second portion 202 may extend in a direction away from the first radiator 100, as long as the length requirement of the second radiator 200 is met. The second portion 202 may extend in the Y direction.

[0071] In some embodiments, as Figure 3As shown, the second portion 202 may be located on a side of the opening 300 close to the edge of the housing 10. For example, the second portion 202 may be disposed on the second side 102 of the housing 10. However, the present disclosure is not limited thereto, as long as the length requirement of the second radiator 200 is met.

[0072] In some embodiments, as Figure 3 As shown, the length of the first portion 201 may be 10-15 mm. For example, the length L21 of the first portion 201 in the X direction may be about 13.7 mm.

[0073] In some embodiments, as Figure 3 As shown, for example, the length L23 of the second portion 202 in the Y direction may be approximately 21.7 mm.

[0074] like Figure 3 As shown, the second radiator 200 may include a second portion 202 extending in the Y direction and a middle portion connecting the first portion 201 and the second portion 202. Figure 3 As shown, since the opening 300 is configured to have a rounded shape, the middle portion may be a curve, and the length L22 of the curve of the middle portion may be about 17.4 mm.

[0075] In some embodiments, the housing 10 may be an insulating member, for example, made of plastic.

[0076] In some embodiments, the first radiator 100 may be made of metal and may be wrapped inside an insulating member.

[0077] In some embodiments, the second radiator 200 may be made of metal and may be wrapped inside an insulating member.

[0078] Figure 7 FIG. 1 is a schematic diagram showing the efficiency of an antenna of an electronic device when an accessory is installed in the electronic device according to an exemplary embodiment. Figure 7 The figure shows the antenna efficiency of the proposed signal enhancement system. In the working frequency band, the peak radiation efficiency of the disclosed solution is -3.2Db and the peak total efficiency is -3.96dB.

[0079] Figure 8 The figure is a diagram showing parameters of an antenna of an electronic device when an accessory is installed in the electronic device according to an exemplary embodiment. Figure 9 FIG. 1 is a schematic diagram showing the efficiency of an antenna of an electronic device when an accessory is installed in the electronic device according to an exemplary embodiment and the efficiency of an antenna of a comparative example. Figure 8 Shown are the antenna S parameters of the proposed signal enhancement system. Figure 9 The comparison results of the proposed scheme and the original scheme are shown in Figure 2.

[0080] exist Figure 9 In the figure, curve A shows the radiation efficiency of antenna 30 when accessory 20 according to the solution of the present disclosure is installed in an electronic device. Curve B shows the radiation efficiency of antenna 30 when the accessory in the comparative example is installed in an electronic device. Curve C shows the total efficiency of antenna 30 when accessory 20 according to the solution of the present disclosure is installed in an electronic device. Curve D shows the total efficiency of antenna 30 when the accessory in the comparative example is installed in an electronic device. From the comparison results, it can be seen that the high-performance signal enhancement system shown in the present invention can improve the radiation efficiency of the antenna by 1Db and significantly improve the operating bandwidth.

[0081] According to the above embodiments, it can be seen that the accessory disclosed herein is provided with a first radiator, and the first radiator can be electrically coupled with the antenna mounted on the camera of the electronic device, exciting a half-wavelength resonance on the first radiator. The current directions of the two currents are consistent, resulting in positive superposition, broadening the bandwidth of the antenna and improving efficiency. The height difference between the first radiator and the antenna mounted on the camera of the electronic device can be less than one-eighth of the wavelength of the antenna's radiation frequency band. Therefore, when the accessory disclosed herein is arranged on the light-entering side of the camera of the electronic device, it can enhance the signal of the antenna while realizing the relevant functions of the accessory, thereby improving the user experience.

[0082] Based on the same concept, the present disclosure also provides an electronic device, comprising any one of the accessories described in the aforementioned embodiments. The accessory is arranged on the light incident side of the camera of the electronic device, and the accessory may include: a housing, provided with an opening exposing the camera, a portion of the housing located around the opening being provided with a first radiator, the first radiator being configured to couple with an antenna provided on the camera decorative part, and the current direction of the first radiator being consistent with the current direction of the antenna, wherein, in the thickness direction of the accessory, the shortest distance between the first radiator and the antenna is less than one-eighth of the wavelength of the antenna's radiation frequency band.

[0083] The electronic device disclosed in the present invention is provided with a first radiator, and the first radiator can be electrically coupled with the antenna installed on the camera of the electronic device to excite half-wavelength resonance on the first radiator. The current directions of the two are consistent to produce positive superposition, which broadens the bandwidth of the antenna and improves efficiency. The height difference between the first radiator and the antenna installed on the camera of the electronic device can be less than one-eighth of the wavelength of the antenna's radiation frequency band. Therefore, when the signal of the antenna of the electronic device disclosed in the present invention can be enhanced, the user experience is improved. It can be understood that the accessories and electronic devices provided in the embodiments of the present invention include hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions.
