[0003] The present application belongs to the field of antenna technology, and specifically relates to an electronic device. Background Art

[0004] In related technologies, compared to cellular communications, satellite communications place more emphasis on directional communications, and have higher requirements for indicators such as directivity and gain. Moreover, since communication satellites are relatively far from the ground, the space path attenuation is large, and communication satellites also have left-handed or right-handed circular polarization characteristics, it is necessary to make the satellite antennas on electronic devices such as mobile phones also have the same circular polarization characteristics to reduce polarization losses and improve the performance of satellite communications. However, since the radiator of the satellite antenna on the electronic device is usually set on the metal frame of the electronic device, it is difficult for the radiator of the satellite antenna to form a field component in the thickness direction of the electronic device, so that it is difficult to form a circular polarization characteristic in the radiation direction of the top of the electronic device, which in turn leads to the problem of poor communication performance of the satellite antenna on the electronic device. Summary of the Invention

[0005] The present application aims to provide an electronic device that can solve the problem of poor communication performance of satellite antennas on electronic devices in related technologies.

[0007] The first radiator is provided with a first feeding point, a second feeding point and a first grounding point, the first radiator is grounded through the first grounding point, and the first feeding point is located between the first grounding point and the first break, and the second feeding point is located between the first grounding point and the second break;

[0008] The feed source is electrically connected to the first radiator through the first feeding point or the second feeding point, so that the circular polarization characteristics of the satellite antenna are consistent with the circular polarization characteristics of the communication satellite.

[0009] In an embodiment of the present application, it can be determined based on the operating frequency band of the satellite antenna whether the feed source is electrically connected to the first radiator through a first feeding point or through a second feeding point, thereby making the circular polarization characteristics of the satellite antenna consistent with the circular polarization characteristics of the communication satellite, and achieving the purpose of improving the communication performance of the satellite antenna.

[0030] An embodiment of the present application provides an electronic device, which is a type of electronic device with an antenna function.

For example, the electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA).

[0031] As shown in Figures 1 to 14, the electronic device includes a frame structure 10 and a satellite antenna 20. The satellite antenna 20 includes a feed source 21 and a first radiator 22. A first slit 113 and a second slit 114 are provided on the top frame 11 of the frame structure 10. The first radiator 22 is provided on the top frame 11 and is located between the first slit 113 and the second slit 114.

[0032] The first radiator 22 is provided with a first feeding point 221, a second feeding point 222 and a first grounding point 223. The first radiator 22 can be grounded through the first grounding point 223. The first feeding point 221 is located between the first grounding point 223 and the first slit 113. The second feeding point 222 is located between the first grounding point 223 and the second slit 114.

[0033] The feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221 or the second feeding point 222 , so that the circular polarization characteristics of the satellite antenna 20 are consistent with the circular polarization characteristics of the communication satellite.

[0034] As shown in Figures 1 and 3, the above-mentioned frame structure 10 can be understood as the outer frame of the electronic device, including a top frame 11, a first side frame 12, a bottom frame 13 and a second side frame 14 adjacent to each other in sequence, that is, the top frame 11, the first side frame 12, the bottom frame 13 and the second side frame 14 connected in sequence can be surrounded to form the frame structure 10, and some functional components of the electronic device can be located in the area enclosed by the frame structure 10.

[0035] The frame structure 10 may be a metal frame, or a frame structure formed by combining metal and non-metal parts, such as a frame structure formed by combining a metal frame and a plastic frame. When the frame structure 10 is a frame structure formed by combining metal and non-metal parts, the metal parts in the frame structure 10 may be used to form the first radiator 22 and other structures.

[0036] In one embodiment, the electronic device includes a display screen, a mainboard, a satellite communication module, a cellular communication module, a speaker model, a camera module, a battery, etc., and the mainboard, camera module, battery and other functional components can be located in the area enclosed by the frame structure 10.

[0037] When the electronic device is a mobile phone, the first side frame 12 and the second side frame 14 can be understood as the left and right frames of the mobile phone; the top frame 11 can be understood as the frame of the mobile phone facing the zenith when the user holds the mobile phone, that is, the frame of the mobile phone facing the zenith where the communication satellite is located, and the bottom frame 13 can be understood as the frame of the mobile phone set opposite to the top frame 11.

[0038] The working frequency band of the satellite antenna 20 is a satellite frequency band, and can realize communication functions such as the call function of the electronic device and the sending and receiving function of satellite short messages.

[0039] The operating frequency band of the satellite antenna 20 may be a satellite frequency band with an uplink frequency band of 1615.68 MHz ± 7 MHz and a downlink frequency band of 2491.75 MHz ± 5 MHz, or a satellite frequency band with an uplink frequency band of 1980 MHz-2010 MHz and a downlink frequency band of 2170 MHz-2200 MHz.

[0040] In one embodiment, the above-mentioned first grounding point 223 can be set in the middle of the first radiator 22 to achieve grounding of the middle of the first radiator 22. For example, the first radiator 22 can be grounded to the metal floor of the electronic device through a metal connecting rib, so that the first radiator 22, the metal floor and the metal connecting rib form a T-shaped antenna structure.

[0041] In one embodiment, there are multiple connecting structures between the frame structure 10 and the metal floor; wherein the multiple connecting structures can be multiple metal connecting ribs between the frame structure 10 and the metal floor, so as to achieve multiple connections between the frame structure 10 and the metal floor, that is, to achieve grounding of the frame structure 10.

[0042] In one embodiment, the length of the first radiator 22 can be 0.5 times λ1, where λ1 is the working wavelength of the working frequency band for the satellite antenna 20 to communicate with the communication satellite in the electronic device. For example, when the working frequency band for the satellite antenna 20 to communicate with the communication satellite is 2170MHz-2200MHz, the length of the first radiator 22 can be set to 0.5 times the working wavelength corresponding to 2170MHz-2200MHz.

[0043] In the embodiment of the present application, by setting the satellite antenna 20 as a T-shaped antenna and setting the length of the first radiator 22 to 0.5 times λ1, the gain performance of the satellite antenna 20 can be improved.

[0044] In the present application, it can be determined based on the operating frequency band of the satellite antenna 20 whether the feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221 or electrically connected to the first radiator 22 through the second feeding point 222, thereby making the circular polarization characteristics of the satellite antenna 20 consistent with the circular polarization characteristics of the communication satellite, and achieving the purpose of improving the communication performance of the satellite antenna 20.

[0045] In one embodiment, the communication satellite can be determined based on the operating frequency band of the satellite antenna 20, and then based on the circular polarization characteristics of the communication satellite, the target feeding point can be determined from the first feeding point 221 and the second feeding point 222, so that the feed source 21 is electrically connected to the first radiator 22 through the target feeding point, thereby making the circular polarization characteristics of the satellite antenna 20 consistent with the circular polarization characteristics of the communication satellite, and achieving the purpose of improving the communication performance of the satellite antenna 20.

[0046] In one embodiment, when the circular polarization characteristic of the communication satellite corresponding to the working frequency band of the satellite antenna 20 is left-hand circular polarization, the feed source 21 can be electrically connected to the first radiator 22 through the first feeding point 221, so that the left-hand circular polarization component of the satellite antenna 20 can be greater than the right-hand circular polarization component, and the satellite antenna 20 can have the same circular polarization characteristic as the communication satellite, that is, the circular polarization characteristic of the satellite antenna 20 is consistent with the circular polarization characteristic of the communication satellite, thereby achieving the purpose of improving the communication performance of the satellite antenna 20.

[0047] When the feed source 21 is electrically connected to the first radiator 22 via the first feed point 221, the directional patterns of the left-hand circularly polarized gain component and the right-hand circularly polarized gain component in the upper hemisphere of the satellite antenna 20 are shown in Figures 11 and 12, respectively. As shown in Figure 11, the maximum value of the left-hand circularly polarized gain component in the upper hemisphere of the satellite antenna 20 is 0.9873 dBi; as shown in Figure 12, the maximum value of the right-hand circularly polarized gain component in the upper hemisphere of the satellite antenna 20 is 0.9073 dBi. It can be seen that when the feed source 21 is electrically connected to the first radiator 22 via the first feed point 221, the left-hand circularly polarized component of the satellite antenna 20 is greater than the right-hand circularly polarized component, thereby increasing the proportion of the left-hand circularly polarized component in the satellite antenna 20 and enabling the satellite antenna 20 to have the same circular polarization characteristics as the communication satellite. That is, the circular polarization characteristics of the satellite antenna 20 are consistent with those of the communication satellite, thereby achieving the purpose of improving the communication performance of the satellite antenna 20.

[0048] It can be understood that when the feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221, the feed source 21 and the second feeding point 222 are in a disconnected state, that is, when realizing the antenna function of the satellite antenna 20, the feed source 21 can only select one of the first feeding point 221 and the second feeding point 222 to realize the electrical connection between the feed source 21 and the first radiator 22.

[0049] In one embodiment, when the circular polarization characteristic of the communication satellite corresponding to the working frequency band of the satellite antenna 20 is right-hand circular polarization, the feed source 21 can be electrically connected to the first radiator 22 through the second feeding point 222, so that the right-hand circular polarization component of the satellite antenna 20 can be greater than the left-hand circular polarization component, and the satellite antenna 20 can have the same circular polarization characteristic as the communication satellite, that is, the circular polarization characteristic of the satellite antenna 20 is consistent with the circular polarization characteristic of the communication satellite, thereby achieving the purpose of improving the communication performance of the satellite antenna 20.

[0050] When the feed source 21 is electrically connected to the first radiator 22 via the second feed point 222, the directional patterns of the left-hand circularly polarized gain component and the right-hand circularly polarized gain component in the upper hemisphere of the satellite antenna 20 are shown in Figures 13 and 14, respectively. As shown in Figure 13, the maximum value of the left-hand circularly polarized gain component in the upper hemisphere of the satellite antenna 20 is 0.9243 dBi; as shown in Figure 14, the maximum value of the right-hand circularly polarized gain component in the upper hemisphere of the satellite antenna 20 is 0.9673 dBi. It can be seen that when the feed source 21 is electrically connected to the first radiator 22 via the second feed point 222, the right-hand circularly polarized component of the satellite antenna 20 is greater than the left-hand circularly polarized component, thereby increasing the proportion of the right-hand circularly polarized component in the satellite antenna 20 and enabling the satellite antenna 20 to have the same circular polarization characteristics as the communication satellite. That is, the circular polarization characteristics of the satellite antenna 20 are consistent with those of the communication satellite, thereby achieving the purpose of improving the communication performance of the satellite antenna 20.

[0051] It can be understood that when the feed source 21 is electrically connected to the first radiator 22 through the second feeding point 222, the feed source 21 and the first feeding point 221 are in a disconnected state, that is, when realizing the antenna function of the satellite antenna 20, the feed source 21 can only select one of the first feeding point 221 and the second feeding point 222 to realize the electrical connection between the feed source 21 and the first radiator 22.

[0052] In one embodiment, a second radiator 111 and a third radiator 112 are further provided on the top frame 11, and the second radiator 111 and the third radiator 112 are respectively located at the two ends of the first radiator 22, and there is a first break 113 between the second radiator 111 and the first radiator 22, and there is a second break between the third radiator 112 and the first radiator 22.

[0053] In this embodiment, by providing the second radiator 111 and the third radiator 112 and adjusting the resonance of the second radiator 111 and the third radiator 112 , the communication performance of the satellite antenna 20 can be further improved.

[0054] Moreover, in order to further improve the communication performance of the satellite antenna 20 , when the feed source 21 is electrically connected to the first radiator 22 , both the second radiator 111 and the third radiator 112 need to be grounded.

[0055] In one embodiment, when the feed source 21 is electrically connected to the first radiator 22 , an end of the second radiator 111 close to the first slit 113 and an end of the third radiator 112 close to the second slit 114 are both grounded.

[0056] In one embodiment, when one end of the second radiator 111 near the first slit 113 and one end of the third radiator 112 near the second slit 114 are grounded, and the feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221, the satellite antenna 20 can excite a rotating current near the first feeding point 221 at the first slit 113, so that the left-handed circular polarization component of the satellite antenna 20 is greater than the right-handed circular polarization component, and the satellite antenna 20 can have the same circular polarization characteristics as the communication satellite, that is, the circular polarization characteristics of the satellite antenna 20 are consistent with the circular polarization characteristics of the communication satellite, thereby achieving the purpose of improving the communication performance of the satellite antenna 20.

[0057] In one embodiment, when one end of the second radiator 111 near the first slit 113 and one end of the third radiator 112 near the second slit 114 are grounded, and the feed source 21 is electrically connected to the first radiator 22 through the second feeding point 222, the satellite antenna 20 can excite a rotating current near the second feeding point 222 at the second slit 114, so that the right-handed circular polarization component of the satellite antenna 20 is greater than the left-handed circular polarization component, and the satellite antenna 20 can have the same circular polarization characteristics as the communication satellite, that is, the circular polarization characteristics of the satellite antenna 20 are consistent with the circular polarization characteristics of the communication satellite, thereby achieving the purpose of improving the communication performance of the satellite antenna 20.

[0058] In one embodiment, as shown in FIG. 4 to FIG. 6 , the electronic device further includes a metal decorative ring 30 , which is coupled to the first radiator 22 , and a ground loading point is provided on the metal decorative ring 30 , which is grounded through the first loading structure.

[0059] In this embodiment, by coupling the metal decorative ring 30 with the first radiator 22, a rotating induced current can be generated on the metal decorative ring 30, thereby increasing the proportion of the left-hand circular polarization component or the right-hand circular polarization component of the satellite antenna 20, thereby achieving the purpose of improving the circular polarization characteristics of the satellite antenna 20.

[0060] In one embodiment, when the feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221 , a clockwise rotating induced current can be generated on the metal decorative ring 30 , thereby increasing the proportion of the left-handed circularly polarized component of the satellite antenna 20 .

[0061] Among them, when the feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221, some comparative parameters of the left-hand circular polarization component gain and the right-hand circular polarization component gain corresponding to the satellite antenna 20 in the zenith direction of the electronic device are detailed in Table 1.

[0062] Table 1

[0063] In one embodiment, when the feed source 21 is electrically connected to the first radiator 22 through the second feeding point 222 , a counterclockwise rotating induced current can be generated on the metal decorative ring 30 , thereby increasing the proportion of the right-handed circularly polarized component of the satellite antenna 20 .

[0064] Among them, when the feed source 21 is electrically connected to the first radiator 22 through the second feeding point 222, some comparison parameters of the left-hand circular polarization component gain and the right-hand circular polarization component gain corresponding to the satellite antenna 20 in the zenith direction of the electronic device are detailed in Table 2.

[0071] As shown in Figure 6, when the metal decorative ring 30 is a ring structure, the grounding loading point on the metal decorative ring 30 can only be set on the ring, and after the first radiator 22 and the metal decorative ring 30 are coupled, the current generated on the metal decorative ring 30 is also concentrated on the ring. Therefore, the position of the ring-shaped metal decorative ring 30 on the electronic device or its grounding position can affect the proportion of the circular polarization component of the satellite antenna 20.

[0072] When the electronic device is a mobile phone, the metal decorative ring 30 can generally be set in the center or on the left, that is, the sheet-shaped metal decorative ring 30 or the ring-shaped metal decorative ring 30 can be set in the center or on the left to increase the proportion of the circular polarization component of the satellite antenna 20.

[0073] In one embodiment, when the annular metal decorative ring 30 is centrally arranged in the electronic device and the feed source 21 is electrically connected to the first radiator 22 through the first feeding point 221, asymmetrically distributed ground loading points can be set on the metal decorative ring 30, and the number of grounding points can be multiple to suppress unnecessary rotary currents and thereby increase the proportion of required rotary currents, thereby achieving the purpose of increasing the proportion of the left-handed circularly polarized component of the satellite antenna 20.

[0074] In one embodiment, when the annular metal decorative ring 30 is arranged on the left in the electronic device and the feed source 21 is electrically connected to the first radiator 22 through the second feeding point 222, asymmetrically distributed ground loading points can be set on the metal decorative ring 30, and the number of grounding points can be multiple to suppress unnecessary rotary currents and thereby increase the proportion of required rotary currents, thereby achieving the purpose of increasing the proportion of right-handed circularly polarized components of the satellite antenna 20.

[0076] The side frame of the frame structure 10 may be a left frame of the electronic device. For example, the side frame of the frame structure 10 may be a first side frame 12 .

[0077] In one embodiment, as shown in FIG7 to FIG10 , a second grounding point 224 and a third grounding point 225 are provided on the first radiator 22. The second grounding point 224 is located between the first feeding point 221 and the first slit 113. The third grounding point 225 is located between the second feeding point 222 and the second slit 114.

[0078] In the case where the feed source 21 is electrically connected to the first radiator 22 via the first feeding point 221 , the second grounding point 224 is grounded via the first impedance structure 23 ;

[0079] When the feed source 21 is electrically connected to the first radiator 22 through the second feeding point 222 , the third grounding point 225 is grounded through the second impedance structure 24 .
