Description

Technical Field

[0001] This application belongs to the field of satellite communication technology, specifically relating to an electronic device. Background Technology

[0002] With the development of communication technology, users have increasingly higher demands for the functions of electronic devices. In addition to traditional cellular communication and positioning / navigation functions, life-saving functions brought by satellite communication are also being introduced into electronic devices. In satellite communication, from the perspective of the entire communication link, the upper hemisphere performance and gain of the antenna are relatively critical parameters in the entire system link. However, in related technologies, it is difficult to achieve good upper hemisphere performance and gain for satellite communication antennas in electronic devices, resulting in a low success rate of establishing communication connections between electronic devices and satellites. Summary of the Invention

[0003] This application aims to provide an electronic device that solves the problem of low success rate in establishing communication connections between electronic devices and satellites.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide an electronic device, comprising:

[0006] The frame includes a first border and a second border connected together, the first border being the border located at the top of the electronic device;

[0007] The floor is attached to the frame, which is installed along the outer perimeter of the floor.

[0008] A printed circuit board, mounted on the ground plane, includes a satellite communication module;

[0009] The antenna includes a ground plane with a clearance area for the first antenna, a slit on the first frame, a first branch of the first antenna at the corner of the first and second frames, and a second branch of the first antenna on the first frame. The first and second branches are connected to the clearance area and coupled through the slit. The ends of the first and second branches away from the slit are connected to the ground plane. The first antenna also includes a first feeding structure, which is located on the first or second branch and connected to the satellite communication module. The length of the first branch is greater than or equal to the length of the second branch.

[0010] In the embodiments of this application, the first and second segments of the first antenna can be formed by the first and second frames of the electronic device through a clearance area set on the ground plane, and by a design such as a gap on the first frame. The first segment is located at the corner of the first and second frames, and the second segment is located on the first frame. The first and second segments are coupled through the gap. The length of the first segment is greater than or equal to the length of the second segment. In this way, at least a part of the first segment and the second segment are located on the first frame at the top of the electronic device. This allows the first antenna to have higher upper hemisphere performance and proportion, thereby improving the success rate of establishing a communication connection between the electronic device and the satellite.

[0034] The following is combined with Figures 1-11 This application describes an electronic device according to an embodiment of the present application.

[0035] Please refer to Figure 1 and Figure 2 The electronic device provided in some embodiments of this application may include:

[0036] The frame 1, the ground plane 2, and the printed circuit board 3 are provided. The frame 1 may include a first frame 11 and a second frame 12 connected together. The first frame 11 is a frame located at the top of the electronic device. The frame 1 is disposed along the outer periphery of the ground plane 2. The printed circuit board 3 is disposed on the ground plane 2 and includes a satellite communication module.

[0037] The ground plane 2 has a clearance area 21 for the first antenna 4. The first frame 11 has a gap 111. The first branch L1 of the first antenna 4 is located at the corner of the first frame 11 and the second frame 12. The first frame 11 also has a second branch L2 of the first antenna 4. The first branch L1 and the second branch L2 are connected to the clearance area 21 and coupled through the gap 111. The ends of the first branch L1 and the second branch L2 away from the gap 111 are both connected to the ground plane 2. The first antenna 4 also includes a first feeding structure 41, which is located on the first branch L1 or the second branch L2 and is connected to the satellite communication module. The length of the first branch L1 is greater than or equal to the length of the second branch L2.

[0038] In this embodiment, as Figure 1As shown, the electronic device may include a frame 1 and a ground plane 2. The frame 1 may be made of metal and may include a first border 11 at the top of the electronic device and a second border 12 connected to the first border 11. It is understood that, taking a mobile phone as an example, the first border 11 may be the top border near components such as the camera, flash, and earpiece, while the second border 12 may be any side border of the mobile phone.

[0039] The first frame 11 and the second frame 12 can be set along the outer periphery of the ground plane 2. In general, taking a mobile phone as an example, the mobile phone can also include a third frame and a fourth frame. These frames can form an open mounting space with the ground plane 2. The mounting space can be used to install structures such as printed circuit boards 3 and brackets 5. The mobile phone can also include a display screen, which can be mounted on the frame 1 to close the open part.

[0040] like Figure 2 As shown, the electronic device may further include a printed circuit board 3, on which wireless circuitry may be disposed. This wireless circuitry can support wireless communication in multiple wireless communication frequency bands. The communication frequency bands processed by the wireless communication circuitry may include satellite navigation system frequency bands, satellite communication frequency bands, cellular telephone communication frequency bands, wireless local area network communication frequency bands, near-field communication frequency bands, ultra-wideband communication frequency bands, or other wireless communication frequency bands. The wireless circuitry responsible for the satellite communication portion can be referred to as a satellite communication module. That is, the printed circuit board 3 may include a satellite communication module.

[0041] like Figure 2 As shown, a clearance area 21 for the first antenna 4 can be provided on the ground plane 2. For example, a hole can be drilled in the ground plane 2 near the corner where the first frame 11 and the second frame 12 intersect to form the clearance area 21.

[0042] A slit 111 can also be provided on the first frame 11. A first stub L1 of the first antenna 4 can be provided at the corner of the first frame 11 and the second frame 12. A second stub L2 of the first antenna 4 can also be provided on the first frame 11. The first stub L1 and the second stub L2 are connected to the clearance area 21 and coupled through the slit 111. The ends of the first stub L1 and the second stub L2 away from the slit 111 are both connected to the ground plane 2. It can be understood that the length of the first stub L1 can be greater than or equal to the length of the second stub L2.

[0043] A first feed structure 41 connected to the satellite communication module can also be set on the first branch L1 or the second branch L2, and the first antenna 4 of the electronic device is composed of the first branch L1, the second branch L2 and the first feed structure 41.

[0044] Reference Figure 3As can be seen from the directional schematic diagram of the first antenna 4 of the provided electronic device with the above-described structure, the first branch L1 and the second branch L2 of the first antenna 4 of the electronic device provided in the embodiments of this application can be formed by the first frame 11 and the second frame 12 of the electronic device through a clearance area 21 set on the ground plane 2, and a gap 111 set on the first frame 11. The first branch L1 is set at the corner of the first frame 11 and the second frame 12, and the second branch L2 is set on the first frame 11. The first branch L1 and the second branch L2 are coupled through the gap. The length of the first branch L1 is greater than or equal to the length of the second branch L2. In this way, at least a part of the first branch L1 and the second branch L2 are located on the first frame 11 at the top of the electronic device. This allows the first antenna 4 to have a higher upper hemisphere performance and proportion, thereby improving the success rate of the electronic device establishing a communication connection with the satellite.

[0045] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the electronic device may further include:

[0046] The second antenna 6 is mounted on the ground plane 2 and can be mounted on the support 5. The second antenna 6 is located near the clearance area 21, which is also the clearance area for the second antenna, and the second antenna shares this clearance area 21. The second antenna 6 includes a grounding structure 61, a second power supply structure 62, and a stub assembly 63. One end of the grounding structure 61 and the second power supply structure 62 is connected to the stub assembly 63, and the other end of the grounding structure 61 passes through the support 5 and connects to the ground plane 2. The other end of the second power supply structure 62 passes through the support 5 and connects to the satellite communication module.

[0047] In this embodiment, the electronic device may further include a bracket 5 and a second antenna 6. For example... Figure 1 As shown, the bracket 5 can be set on the grounding plate 2 and can be set close to the first frame 11 and the second frame 12, that is, the distance between the bracket 5 and the first frame 11 and the second frame 12 is shorter than that between the other frames.

[0048] The second antenna 6 can be mounted on the bracket and share the clearance area 21. For example, the second frame 12 can be the left frame of the electronic device, then the clearance area 21 is located at the upper left corner of the electronic device. In other words, the first antenna 4 is located at the upper left corner of the electronic device, and the second antenna 6 can also be located in the upper left corner area of ​​the electronic device.

[0049] The second antenna 6 may include a ground feed structure 61, a second power feed structure 62, and a stub assembly 63. For example... Figure 4 As shown, the branch component 63 can be mounted on the support 5. (As indicated...) Figure 5As shown, one end of the grounding structure 61 and the second power supply structure 62 can be connected to the stub assembly 63, the other end of the grounding structure 61 can pass through the bracket 5 and be connected to the grounding plate 2, and the other end of the second power supply structure 62 can pass through the bracket 5 and be connected to the satellite communication module on the printed circuit board 3.

[0050] In this way, the electronic device can have both a first antenna 4 and a second antenna 6. Multiple satellite antennas can give the entire antenna system of the electronic device a larger radiating aperture and higher radiation efficiency, thereby increasing the gain of the satellite antenna and improving the success rate of establishing a communication connection between the electronic device and the satellite.

[0051] In some embodiments, the branch component 63 includes N branches connected in sequence, P branches of the N branches are parallel to the second branch L2 on the first border 11, and Q branches of the N branches are parallel to the first branch L1 on the second border 12, where P, Q and N are integers greater than or equal to 1, and the sum of P and Q is N.

[0052] Among them, at least a portion of the current direction of the Q branches is the same as the current direction of the first branch L1, and at least a portion of the current direction of the P branches is the same as the current direction of the second branch L2.

[0053] In this embodiment, the branch component 63 of the second antenna 6 may include multiple branches, wherein at least one branch is parallel to the second branch L2 on the first border 11, and at least one branch is parallel to the first branch L1 on the second border 12.

[0054] For example, such as Figure 5 As shown, the stub assembly 63 may include two stubs, one of which is parallel to the second stub L2 on the first frame 11, and the other stub is parallel to the first stub L1 on the second frame 12. It can be understood that the current direction of the two stubs can be the same as the current direction of the first stub L1 and the second stub L2, respectively. In this way, the currents in the same direction in the entire antenna system of the electronic device are superimposed, thereby improving the directivity of the antenna system and further enhancing the gain of the satellite antenna.

[0055] like Figure 8 As shown, there can be two or more branches parallel to the second branch L2 on the first border 11 and the first branch L1 on the second border 12. In this case, the multiple branches can form a ring structure.

[0056] In some examples, among the multiple branches parallel to the first branch L1 on the second frame 12, some or all of the branches may have the same current direction as the first branch L1, while the current direction of the remaining branches may be opposite to the current direction of the first branch L1. By designing the position and size of the branches, the branches with the same current direction can be much larger than the branches with the opposite current direction, thereby reducing the impact of the opposite current direction on the reduction of current intensity, so that the overall current intensity still has superposition.

[0057] Similarly, among the multiple branches parallel to the second branch L2 on the first frame 11, some or all of the branches may have the same current direction as the second branch L2, while the current direction of the remaining branches may be opposite to that of the second branch L2. Through the design of the branch positions and sizes, the branches with the same current direction can be made much larger than the branches with the opposite current direction, thereby reducing the impact of opposite current directions on current intensity reduction and ensuring that the overall current intensity still has superposition. In this way, the current in the same direction is superimposed in the entire antenna system of the electronic device, which can improve the directivity of the antenna system and further improve the gain of the satellite antenna.

[0058] In other examples, by setting a current zero point on the stub, the current direction of some stubs in the stub assembly 63 can be avoided from being opposite to the current direction of the first stub L1 and the second stub L2. This can further increase the current intensity in the same direction, thereby further improving the directivity of the antenna system and increasing the gain of the satellite antenna.

[0059] In some embodiments, the N branches may include a third branch L3 and a fourth branch L4. The third branch L3 is parallel to the first branch L1 on the second frame 12, and the current direction of the third branch L3 is the same as the current direction of the first branch L1. The fourth branch L4 is parallel to the second branch L2 on the first frame 11, and the current direction of the fourth branch L4 is the same as the current direction of the second branch L2.

[0060] In this embodiment, as mentioned above, the branch component 63 may include two branches, namely a third branch L3 and a fourth branch L4. Figure 5 As shown, the third branch L3 can be parallel to the first branch L1 on the second border 12, and the fourth branch L4 can be parallel to the second branch L2 on the first border 11.

[0061] The first power supply structure 41 can be installed on the first branch L1, and the grounding structure 61 and the second power supply structure 62 can both be installed on the third branch L3. Thus, as... Figure 6As shown, the current direction of the third branch L3 can be the same as the current direction of the first branch L1, and the current direction of the fourth branch L4 can be the same as the current direction of the second branch L2.

[0062] Please see Figure 3 and Figure 7 Compared to the case where the electronic device only includes the first antenna 4, in this embodiment, the second antenna 6 causes the current of the entire antenna system of the electronic device to be superimposed in the same direction, which improves the directivity of the antenna system, further improves the gain of the satellite antenna, and thus further improves the success rate of the electronic device establishing a communication connection with the satellite.

[0063] In some embodiments, when N is an integer greater than 3, one of the grounding structure 61 and the second power supply structure 62 is connected to the first branch among the N branches, and the other is connected to the last branch among the N branches. There is a target branch among the N branches, and a current zero point is formed on the target branch, so that among the other branches of the N branches excluding the target branch, the current direction of the branch parallel to the first branch L1 on the second frame 12 is the same as the current direction of the first branch L1, and the current direction of the branch parallel to the second branch L2 on the first frame 11 is the same as the current direction of the second branch L2.

[0064] In this embodiment, as mentioned above, the branch component 63 may have two or more branches parallel to the second branch L2 on the first frame 11 and the first branch L1 on the second frame 12. Two or more branches connected sequentially can form a ring, for example, as... Figure 8 As shown, the second antenna 6 may include a fifth branch L5, a sixth branch L6, a seventh branch L7, an eighth branch L8, a ninth branch, and a tenth branch L10 connected in a ring shape. In this case, one of the grounding structure 61 and the second power supply structure 62 can be located on the fifth branch L5, and the other can be located on the tenth branch L10. Among the fifth branch L5, the sixth branch L6, the seventh branch L7, the eighth branch L8, the ninth branch, and the tenth branch L10, there may be a target branch that forms a zero-current point.

[0065] For example, the seventh branch L7 can be used as the target branch, that is, a current zero point can be formed on the seventh branch L7. Thus, as... Figure 9 As shown, except for the seventh branch L7, the current directions of the sixth branch L6, the eighth branch L8 and the tenth branch L10 can be the same as the current direction of the first branch L1, and the current directions of the fifth branch L5 and the sixth branch L6 can be the same as the current direction of the second branch L2.

[0066] It is understood that the above structure is only an example to illustrate the technical solution of this embodiment. The specific number of branches, the position and size of each branch of the branch component 63 can be designed according to actual needs to satisfy the target branch with zero current, so that there are no branches in the N branches with the opposite current direction to the first branch L1 and the second branch L2.

[0067] Please see Figure 10 This results in a significant superposition of the current intensity of the entire antenna system in the same direction, further increasing the directivity of the antenna system in the far field, improving the gain of the satellite antenna, and effectively increasing the success rate of establishing communication connections between electronic devices and satellites.

[0068] In some embodiments, the N branches include a fifth branch L5, a sixth branch L6, a seventh branch L7, an eighth branch L8, a ninth branch, and a tenth branch L10 connected in a ring in sequence, and the fifth branch L5, the seventh branch L7, and the ninth branch L9 are parallel to the first branch L1 on the second frame 12, and the sixth branch L6, the eighth branch L8, and the tenth branch L10 are parallel to the second branch L2 on the first frame 11.

[0069] Among them, the second power supply structure 62 is connected to the fifth branch L5, the grounding structure 61 is connected to the tenth branch L10, and the seventh branch L7 is the branch farthest from the first branch L1 among the N branches, and a current zero point is formed on the seventh branch L7.

[0070] like Figure 8 As shown, the branch assembly 63 may include a fifth branch L5, a sixth branch L6, a seventh branch L7, an eighth branch L8, a ninth branch, and a tenth branch L10 connected in a ring shape. The fifth branch L5, the seventh branch L7, and the ninth branch L9 may be arranged parallel to the first branch L1 on the second frame 12, and the sixth branch L6, the eighth branch L8, and the tenth branch L10 may be arranged parallel to the second branch L2 on the first frame 11.

[0071] The second feed structure 62 can be connected to the fifth branch L5, the ground feed structure 61 can be connected to the tenth branch L10, and a current zero point is formed on the seventh branch L7. Thus, as... Figure 9 As shown, the current can flow sequentially from the second feed structure 62 to the fifth branch L5 and the sixth branch L6, and also sequentially from the ground feed structure 61 to the tenth branch L10, the ninth branch L9 and the eighth branch L8.

[0072] It is evident that the current directions of the sixth stub L6, the eighth stub L8, and the tenth stub L10 can be the same as the current direction of the first stub L1, and the current directions of the fifth stub L5 and the sixth stub L6 can be the same as the current direction of the second stub L2. This results in a significant superposition of the current intensity of the entire antenna system in the same direction, further increasing the directivity of the antenna system in the far field, improving the gain of the satellite antenna, and effectively increasing the success rate of establishing communication connections between electronic devices and satellites.

[0073] In some embodiments, the total length of the N stubs is equal to half the wavelength of the center frequency of the antenna operating band, and the length from the position of the grounding structure 61 to the midpoint of the target stub is equal to the length from the position of the second feeding structure 62 to the midpoint of the target stub.

[0074] In this embodiment, "equal to" can include approximate equality, and can have a certain range of deviation. In other words, the total length of the N stubs can be approximated to half the wavelength of the center frequency of the antenna operating band, and the length from the position of the grounding structure 61 to the midpoint of the target stub can be approximately the same as the length from the position of the second feeding structure 62 to the midpoint of the target stub.

[0075] For example, such as Figure 8 As shown, the fifth stub L5, sixth stub L6, seventh stub L7, eighth stub L8, ninth stub, and tenth stub L10 are approximately half the wavelength of the antenna's operating frequency band center frequency. The length from the position of the second feed structure 62, passing through the midpoint of the fifth stub L5, sixth stub L6, to the seventh stub L7, is approximately one-quarter of the antenna's operating frequency band center frequency. The length from the position of the grounding structure 61, passing through the midpoint of the tenth stub L10, ninth stub, eighth stub L8, to the seventh stub L7, is approximately one-quarter of the satellite antenna's operating frequency band center frequency.

[0076] In this way, a zero current point can be formed on the seventh branch L7, so that the current direction of the sixth branch L6, the eighth branch L8 and the tenth branch L10 can be the same as the current direction of the first branch L1, and the current direction of the fifth branch L5 and the sixth branch L6 can be the same as the current direction of the second branch L2, thus achieving the purpose of superimposing the current intensity.

[0077] In some embodiments, when there are multiple radio frequency paths in the satellite communication module, the first feeding structure 41 and the second feeding structure 62 are respectively connected to one radio frequency path of the satellite communication module.

[0078] In this embodiment, if the satellite communication module has multiple radio frequency (RF) paths, the first antenna 4 and the second antenna 6 of the electronic device can be connected to different RF paths respectively. That is, the first feeding structure 41 can be connected to one RF path of the satellite communication module, and the second feeding structure 62 can be connected to another RF path of the satellite communication module.

[0079] In this way, the signal energy fed by the satellite communication module can reach the first antenna 4 and the second antenna 6 through their respective radio frequency paths, so that both antennas can receive the signal energy, have a larger radiation aperture, obtain higher radiation efficiency, and improve the gain of the satellite antenna.

[0080] In some embodiments, when there is a radio frequency path in the satellite communication module, the printed circuit board 3 is also provided with a first transmission line 31 and a second transmission line 32 that are connected to each other. The end of the first transmission line 31 away from the second transmission line 32 is connected to the first feeding structure 41, and the end of the second transmission line 32 away from the first transmission line 31 is connected to the second feeding structure 62. The connection point 33 between the first transmission line 31 and the second transmission line 32 is connected to the radio frequency path.

[0081] In this embodiment, if the satellite communication module has only a single radio frequency path, then as follows: Figure 11 As shown, the printed circuit board 3 can also be provided with a first transmission line 31 and a second transmission line 32 that are interconnected. One end of the first transmission line 31 is connected to the first power supply structure 41, and one end of the second transmission line 32 is connected to the second power supply structure 62. The other ends of the first transmission line 31 and the second transmission line 32 converge to form a connection point 33, which can be connected to the radio frequency path.

[0082] It is understood that the first transmission line 31 and the second transmission line 32 can adopt a microstrip line structure or a stripline structure, and the specific choice can be made according to actual needs. No specific limitation is made here.

[0083] In this way, an energy distributor made of the first transmission line 31 and the second transmission line 32 can be used to supply power to the first antenna 4 and the second antenna 6. The first transmission line 31 and the second transmission line 32 can distribute the signal energy fed by the satellite communication module to the first antenna 4 and the second antenna 6, so that both antennas can receive signal energy, have a larger radiation aperture, obtain higher radiation efficiency, and improve the gain of the satellite antenna.

[0084] In some embodiments, the first transmission line 31 and the second transmission line 32 have the same line width, and the length of the first transmission line 31 is equal to the length of the second transmission line 32.

[0085] In this embodiment, "same" and "equal" can both include approximately identical cases, with a certain range of deviations allowed. In other words, the first transmission line 31 and the second transmission line 32 have the same linewidth and similar lengths, so their impedances can be similar to ensure that the phases of the first transmission line 31 and the second transmission line 32 are close, resulting in better energy distribution.

[0086] In some examples, lumped parameter devices such as capacitors and inductors can be connected at connection point 33 to perform impedance matching on the antenna system formed by the first antenna 4 and the second antenna 6, further improving the energy distribution effect.

[0087] Other components of the electronic device according to the embodiments of this application, such as the display screen and camera module, as well as its operation, are known to those skilled in the art and will not be described in detail here.

[0088] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0089] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
