[0030] In one embodiment, see Figure 1 , an electronic device is provided, comprising a radiation accessory 100 and a switch switching module 200, wherein the radiation accessory 100 has a plurality of connection points ( Figure 1 The radiation accessory 100 is shown to have four connection points located at positions 1 to 4, at least some of the connection points can be conductively connected to the first feed source S1 to receive the feed signal input by the first feed source S1, and at least some of the connection points can be conductively connected to the metal floor G1. The two first ends of the switch switching module 200 are respectively connected to the first feed source S1 and the metal floor G1, and the multiple second ends of the switch switching module 200 are respectively connected to the multiple connection points.
[0031] The switch module 200 is used to switch the connection between the first feed source S1 and the first target feed point, and to switch the connection between the metal floor G1 and the target ground point. The first target feed point and the target ground point are determined according to the holding direction of the electronic device, so that the radiation accessory 100 excites and generates a radiation field corresponding to the holding direction. The first target feed point is one of at least some of the connection points that can be conductively connected to the first feed source S1, and the target ground point is at least one of at least some of the connection points that can be conductively connected to the metal floor G1.
[0032] Among them, the electronic device can be a handheld device, a vehicle-mounted device, a wearable device, a computing device or other processing device connected to a wireless modem, as well as various forms of user equipment (UE) (for example, a mobile phone), a mobile station (MS), etc. For the convenience of description, the above-mentioned devices are collectively referred to as electronic devices.
[0033] Among them, the radiation accessory 100 can be used as an independently set antenna radiator in the electronic device, including a flexible printed circuit (FPC) antenna radiator, a laser direct structuring (LDS) antenna radiator, a print direct structuring (PDS) antenna radiator, and a metal radiation branch; the radiation accessory 100 can also be a metal decorative part located on the surface of the back shell of the electronic device, which can not only decorate the electronic device to meet the needs of beautifying the appearance of the device, but also have the performance of the antenna to avoid occupying the antenna design space inside the electronic device and increase the clearance area of the antenna. Optionally, the electronic device may include a display screen assembly and a frame, and the display screen assembly also includes a display screen, the display screen is used to display information and provide an interactive interface for the user, and the frame is arranged on the periphery of the display screen assembly to support and protect the display screen assembly, so the back shell of the above-mentioned electronic device can be understood as a cover plate facing away from the display screen and connected to the frame. It should be noted that the radiation accessory 100 in this embodiment can be either an independent antenna radiator inside the electronic device or an external metal decorative part reused as an antenna radiator. This embodiment does not limit the existence form of the radiation accessory 100. Optionally, the radiation accessory 100 may be a closed or non-closed structure, and its shape may be a circular ring, an elliptical ring, a square ring or other irregular shapes. Figure 1 Taking the reuse of the metal decorative part as the radiation accessory 100 as an example, the electronic device is a mobile phone as an example for explanation.
[0034] Further, the radiation accessory 100 has a plurality of spaced connection points, at least some of which can be used as feeding points for conducting connection to the first feed source S1. For example, the connection points at positions 1 and 2 can be used as feeding points that can be conducted to the first feed source S1. The first feed source S1 can be a device that can generate a feeding signal on a circuit board of an electronic device. The circuit board can be a printed circuit board (PCB) or a flexible printed circuit (FPC). In addition, the radiation accessory 100 also has at least some of its connection points that can be used as grounding points for conducting connection to the metal floor G1. For example, the connection points at positions 3 and 4 can be used as grounding points that can be conducted to the metal floor G1. The metal floor G1 can be a grounding terminal located on a circuit board or a metal middle frame as a reference potential. Therefore, the radiation accessory 100 can receive the feeding signal input by the first feed source S1 under the action of forming an electrical connection between some of the connection points and the first feed source S1, and under the action of forming an electrical connection between some of the connection points and the metal floor G1, so as to radiate a radio frequency signal.
[0035] Furthermore, since the transceiver frequency band of the radiation accessory 100 is related to the electrical length of the radiation accessory 100, the switch module 200 is used to switch and access different connection points to serve as the feeding point and the grounding point respectively, thereby changing the positions of the feeding point and the grounding point on the radiation accessory 100 to control the change of the electrical length of the radiation accessory 100, so that the radiation accessory 100 can support the frequency band required for the current electronic device to work. Among them, the switch module 200 has two first ends and multiple second ends, the two first ends of the switch module 200 are respectively connected to the first feed source S1 and the metal floor G1, and the multiple second ends of the switch module 200 are respectively connected to the multiple connection points. Thus, the switch module 200 can switch the feeding path from different connection points to the first feed source S1, and switch the grounding path from different connection points to the metal floor G1, and then the positions of the connection points connected to the first feed source S1 and the metal floor G1 are changed, and the resonant frequency of the radiation accessory 100 is adjusted to adapt to the working frequency band of the electronic device.
[0036] Furthermore, the holding direction of an electronic device can be understood as the direction in which a user holds the device, which may include horizontal holding and vertical holding. Since the antenna radiation efficiency of the electronic device is different in the horizontal and vertical usage scenarios, for example, when the holding direction of the electronic device is vertical holding, the signal receiving and transmitting efficiency of the antenna close to the top frame area is high, but when the holding direction of the electronic device is changed to horizontal holding, the antenna close to the top frame area is easily blocked by the user's hand, thereby affecting the communication signal of the antenna. Therefore, the electronic device can determine the first target feeding point and the target grounding point corresponding to the holding direction from the multiple connection points on the radiation accessory 100, and then control the switch switching module 200 to respectively adjust the connection point positions of the radiation accessory 100 connected to the first feed source S1 and the metal floor G1, so that the radiation accessory 100 can radiate the radio frequency signal radiation range corresponding to the current holding direction in different holding posture scenarios. That is, by switching the path from the first target feeding point corresponding to the holding direction of the electronic device to the first feed source S1, and switching the path from the target grounding point corresponding to the holding direction of the electronic device to the metal floor G1 through the switch switching module 200, the radiation accessory 100 changes the current distribution and current path to adapt to the reception and radiation of radio waves in different holding scenarios. Without setting antenna structures in different areas, one radiation accessory 100 can ensure the communication performance of the electronic device in different holding postures.
[0037] Exemplarily, if the sensing element of the electronic device recognizes that the current holding direction of the electronic device is vertical holding, the first target feeding point and the target grounding point are selected and switched among the multiple connection points of the radiation accessory 100 through the switch switching module 200, so that a selected connection point is connected to the first feed source S1 as the first target feeding point, and another selected connection point is connected to the metal floor G1 as the target grounding point, thereby forming a current distribution and current path corresponding to the vertical holding scenario on the radiation accessory 100, so that in the vertical screen display mode, the radiation proportion of the half area of the radiation accessory 100 close to the upper frame is increased, that is, the maximum direction of the radiation intensity is concentrated in the upper half of the vertical screen, and the strongest radiation direction is toward the upper frame.
[0038] If the sensing element of the electronic device recognizes that the current holding direction of the electronic device is horizontal holding, the first target feeding point and the target grounding point are selected and switched among the multiple connection points of the radiation accessory 100 through the switch switching module 200, so as to form a current distribution and current path corresponding to the horizontal holding scenario on the radiation accessory 100, thereby increasing the radiation proportion of the half area of the radiation accessory 100 close to the left frame in the horizontal screen display mode, that is, the maximum radiation intensity is concentrated in the upper half of the horizontal screen, and the strongest radiation direction is toward the left frame. Based on this, according to the holding direction of the electronic device, the function of each connection point on the radiation accessory 100 can be adjusted in time, so that the radiation accessory 100 generates a radiation field range corresponding to the holding direction, thereby improving the radiation efficiency and RF performance of the radiation accessory 100 in different holding scenarios.
[0039] The above-mentioned electronic device includes a radiation accessory 100 and a switch switching module 200. The radiation accessory 100 has a plurality of connection points arranged at intervals. The positions of the first target feeding point and the target grounding point are determined based on the holding direction of the electronic device. The switch switching module 200 correspondingly switches on the connection between the first target feeding point and the first feed source S1, and switches on the connection between the target grounding point and the metal floor G1, so that the radiation accessory 100 is stimulated to generate a current distribution and a current path corresponding to the holding direction, and then generates a radiation field corresponding to the holding direction, so as to adapt to the reception and radiation of radio waves in different holding scenarios, thereby improving the communication performance of the electronic device in different holding scenarios.
[0040] In one embodiment, the electronic device includes a middle frame and a rear shell that are arranged relatively, the middle frame includes a middle plate and an upper frame, a first side frame, a lower frame, and a second side frame that are arranged around the side of the middle plate and connected end to end, and the radiation accessory is arranged on the rear shell. When the electronic device is held in a first direction, the strongest radiation direction of the radiation field generated by the radiation accessory is directed to the first side frame or the second side frame, and the first direction is the direction from the upper frame to the lower frame; when the electronic device is held in a second direction, the strongest radiation direction of the radiation field generated by the radiation accessory is directed to the upper frame or the lower frame, and the second direction is the direction from the first side frame to the second side frame.
[0041] Among them, the upper frame, the first side frame, the lower frame and the second side frame connected end to end are roughly formed into a rectangular frame shape, and the formed frame-shaped plane is provided with a back shell used as a back protection structure of the electronic device. The specific connection between each frame can be a right-angle connection or an arc transition connection. It should be noted that the radiation accessory in this embodiment is a metal decorative part provided on the back shell. It can be understood that when the electronic device is used as a mobile phone, the lower half of the mobile phone is usually held in one hand for a long time, so some short-range antennas are generally designed in the upper half of the mobile phone. In addition, multiple cellular antennas of various frequency bands are arranged in the upper half of the mobile phone, resulting in a very tight space in the upper half, and even low isolation problems are easily generated between antennas with similar frequency bands, affecting the antenna performance. Therefore, in this embodiment, the metal decorative parts on the back shell of the electronic device are reused as radiation accessories, so that the metal decorative parts have the performance of antenna radiators, thereby saving the antenna design space inside the electronic device, alleviating the pressure of tight antenna layout space and increasing the available area of antenna design.
[0042] Among them, the holding direction of the electronic device is holding along the first direction, which can be understood as the horizontal holding described above, and the holding direction of the electronic device is holding along the second direction, which can be understood as the vertical holding described above. Furthermore, the first side frame can be one of the frame located on the left side in the second direction and the frame located on the right side in the second direction, and the second side frame can be the other of the frame located on the left side in the second direction and the frame located on the right side in the second direction, such as Figure 2 As shown, Figure 2 The first side frame 500 is a left side frame and the second side frame 600 is a right side frame. Figure 2 The four connection points shown can be respectively connected to the first feed source S1 and the metal floor G1, wherein the connection between the connection points at positions 1 and 2 and the first feed source S1 is represented by a solid line, the connection between the connection points at positions 1 and 2 and the metal floor G1 is represented by a dotted line, the connection between the connection points at positions 3 and 4 and the metal floor G1 is represented by a solid line, and the connection between the connection points at positions 3 and 4 and the first feed source S1 is represented by a dotted line.
[0043] In the case where the holding direction of the electronic device is holding along the first direction X, assuming that the lower frame 400 is provided with a USB interface, holding along the first direction X can be understood as the user holding the upper frame 300 and / or the lower frame 400 ( Figure 2 The figure shows a situation where the user's hands simultaneously hold part of the upper frame 300 and the lower frame 400), so that the USB interface faces the left side in the first direction X, then the first side frame 500 is the side away from the user or the ground, and the second side frame 600 is the side close to the user or the ground, that is, the electronic device is in a horizontal holding state at this time, and the switch switching module then selects and switches the connection points on the radiation accessory 100 that match the horizontal holding state to serve as the first target feeding point and the target grounding point, respectively. For example, in this embodiment, the connection point at position 1 is used as the first target feeding point, and the connection between the connection point at position 1 and the first feed source S1 is turned on through the first switch unit in the switch switching module, and the connection points at positions 2 and 3 are used as two target grounding points. It should be noted that the number of target grounding points can be multiple to cover the grounding requirements of different holding scenarios. In this embodiment, two target grounding points are used as an example for illustration.
[0044] Furthermore, the connection between the connection points at positions 2 and 3 and the metal floor G1 is turned on by the second switch unit in the switch switching module, while the connection point at position 4 is in a suspended state to form an equivalent open circuit effect. The radiation accessory 100 operates in the first resonant mode to form a current distribution adapted to the horizontal holding state of the electronic device. Figure 3 , Figure 3 The radiation pattern of the electronic device in the horizontal holding state is shown. At this time, the maximum direction of the radiation pattern of the radiation accessory 100 is concentrated in the upper half of the electronic device in the horizontal screen state, and the strongest radiation direction is toward the first side frame 500, and combined with the reference Figure 4 , Figure 4 A schematic diagram showing the proportion of the upper hemisphere of an electronic device in a horizontal holding state is shown, wherein the abscissa is the frequency in GHz, the ordinate is the proportion, and point 1 is the energy integral of the upper hemisphere, the abscissa of point 1 is 1.175GHz, and the ordinate is -8.4768, point 2 is the energy integral of the entire sphere, the abscissa of point 2 is 1.175GHz, and the ordinate is -6.3181, and the ordinate difference between point 1 and point 2 is the proportion of the upper hemisphere, specifically -2.16dB, that is, the proportion of the upper hemisphere in the horizontal holding direction is 61%, thereby achieving an upper hemisphere duty cycle of more than 50% in the horizontal screen state of the electronic device. Similarly, when the first side frame 500 (left side frame) is the side close to the user or the ground, and the second side frame 600 (right side frame) is the side away from the user or the ground, the strongest radiation direction of the radiation pattern of the radiation accessory 100 in the horizontal screen state is toward the second side frame 600.
[0045] When the electronic device is held in the second direction, please refer to Figure 5 It should be noted that Figure 5 The four connection points shown can be respectively connected to the first feed source S1 and the metal floor G1, and the connection between the connection points at positions 1 and 2 and the first feed source S1 is represented by a solid line, the connection between the connection points at positions 1 and 2 and the metal floor G1 is represented by a dotted line, the connection between the connection points at positions 3 and 4 and the metal floor G1 is represented by a solid line, and the connection between the connection points at positions 3 and 4 and the first feed source S1 is represented by a dotted line.
[0046] Further, holding along the second direction Y can be understood as the user holding the first side frame 500 and / or the second side frame 600 ( Figure 5 4 shows a case where a user holds part of the lower frame 400 in one hand, with the USB interface facing the ground. The lower frame 400 is the side close to the user or the ground, and the upper frame 300 is the side away from the user or the ground. That is, the electronic device is in a vertical holding state at this time. The switch switching module selects and switches the connection points on the radiation accessory 100 that match the vertical holding state to serve as the first target feeding point and the target grounding point, respectively. For example, Figure 5 The connection point at position 2 is used as the first target feeding point, and the connection between the connection point at position 2 and the first feed source S1 is conducted through the first switch unit in the switch switching module, and the connection points at positions 1 and 4 are used as two target grounding points, and the connection between the connection points at positions 1 and 4 and the metal floor G1 is conducted through the second switch unit in the switch switching module, while the connection point at position 3 is in a suspended state to form an equivalent open circuit effect. The radiation accessory 100 operates in the second resonant mode to form a current distribution adapted to the vertical holding state of the electronic device, combined with the reference Figure 6 , Figure 6 The radiation pattern of the electronic device in the vertical holding state is shown. At this time, the maximum direction of the radiation pattern of the radiation accessory 100 is concentrated in the upper half of the electronic device in the vertical screen state, and the strongest radiation direction is toward the upper frame 300, and combined with the reference Figure 7 , Figure 7A schematic diagram showing the proportion of the upper hemisphere of an electronic device in a vertical holding state is shown, wherein the horizontal coordinate is the frequency in GHz, the vertical coordinate is the proportion, and point 1 is the energy integral of the upper hemisphere, the horizontal coordinate of point 1 is 1.175GHz, and the vertical coordinate is -9.7099, point 2 is the energy integral of the entire sphere, the horizontal coordinate of point 2 is 1.175GHz, and the vertical coordinate is -6.8552, and the vertical coordinate difference between point 1 and point 2 is the proportion of the upper hemisphere, specifically -2.85dB, that is, the proportion of the upper hemisphere in the horizontal holding direction is 52%, thereby achieving an upper hemisphere duty cycle of more than 50% in the vertical screen state of the electronic device. It should be noted that the current distribution and current path of the second resonance mode are different from those of the first resonance mode. Similarly, when the lower frame 400 is the side away from the user or the ground, and the upper frame 300 is the side close to the user or the ground, the strongest radiation direction of the radiation pattern of the radiation accessory 100 in the vertical screen state is toward the lower frame 400.
[0047] Furthermore, when the electronic device is in the working modes of being held in the first direction and being held in the second direction, respectively, the radiation efficiency and upper hemisphere occupancy of the radiation accessory are as shown in Table 1.
[0048] Table 1
[0049] Holding in the first direction Hold in the second direction Radiation efficiency EFF.(dB) -7.6 -7.8 Upper Hemisphere Proportion 61% 52%
[0050] Based on this, based on the holding direction of the electronic device, the switch switching module selects the position of the first target feeding point and the target grounding point on the radiating accessory 100, thereby changing the current distribution on the radiating accessory 100 to operate in a resonant mode corresponding to the holding direction, and generate a radiation field range that matches the holding direction, so that the radiation energy is concentrated in the upper half of the electronic device, thereby improving the upper hemisphere radiation efficiency of the radiating accessory 100 in different holding scenarios of the electronic device, and satisfying the complementary directional patterns of the radiating accessory in different holding scenarios.
[0051] In one embodiment, Figure 5 As shown, the radiation accessory 100 is disposed on the rear shell close to the first side frame 500 and the upper frame 300, that is, the radiation accessory 100 is as a whole close to the upper left area of the rear shell to prevent the user from holding the electronic device and blocking the radiation accessory 100 and deteriorating the antenna performance.
[0052] In one embodiment, the radiation accessory is used to support the reception and transmission of the first frequency band signal under the stimulation of the first feed source, and the first frequency band signal includes the GPS frequency band signal. The Global Positioning System (GPS) is a high-precision radio navigation positioning system based on artificial earth satellites, which can provide accurate geographic location, vehicle speed and precise time information anywhere in the world and in near-Earth space. Since the satellite is in the air, the electronic equipment needs to make the main radiation direction face the upper space, so as to improve the efficiency of receiving and transmitting signals in the upper hemisphere area to improve the positioning accuracy.
[0053] Optionally, the GPS frequency band signal may include signals of three frequency bands, namely GPS-L1, GPS-L2 and GPS-L5. Taking the GPS-L5 frequency band signal as an example, the existing technical solutions usually make the GPS-L5 antenna into an FPC antenna placed on a PCB bracket, which causes the limited space of the electronic device to be occupied, resulting in a poor environment around the antenna and small clearance, or the GPS-L5 antenna is designed with a co-aperture with the cellular antenna, but this form of design can only meet the performance of the cellular antenna in the co-aperture. Due to the large number of border antennas and insufficient size, the radiation length of the GPS-L5 antenna will be compressed and sacrificed, resulting in reduced radiation performance of the GPS-L5 antenna. Therefore, the metal decorative parts on the back cover of the electronic device are reused as radiation accessories that can radiate GPS frequency band signals. On the one hand, it can avoid occupying additional antenna design space, increase the antenna clearance area and alleviate the pressure on the antenna layout space; on the other hand, by selecting different connection points on the radiation accessories to serve as the first target feeding point and target grounding point of the GPS antenna frequency band respectively, the radiation accessories radiate the radiation range of the radio frequency signal corresponding to the current holding direction in different holding directions of the electronic device, so that the maximum direction of the radiation pattern is concentrated in the upper half of the electronic device in the current holding state, so that the main radiation direction is toward the upper space so that the upper hemisphere of the GPS frequency band signal has a high duty cycle, thereby improving the upper hemisphere radiation efficiency of the radiation accessory.
[0054] In one embodiment, Figure 5 As shown, the rear shell has a functional component area 700 , the radiation accessory 100 is arranged around the functional component area 700 , and the first target feeding point is located on a side of the radiation accessory 100 away from the functional component area 700 .
[0055] Optionally, the functional component area 700 may be provided with a sensor module or a camera module, etc. The sensor module may be an optical sensor, a distance sensor or a fingerprint sensor, etc. Among them, the radiation accessory 100 is distributed along the periphery of the functional component area 700. Since the position on the circuit board corresponding to the functional component area 700 needs to be removed and the board broken in order to place the corresponding device module, it is necessary to select a connection point on the radiation accessory 100 away from the functional component area 700 as the first target feeding point to reduce the problem of large loss caused by the long wiring winding caused by the hollow circuit board. The wiring can be understood as the wiring from the first target feeding point to the first feed source device at the front end. Exemplarily, if the functional component area 700 is distributed with a camera module, and the camera module is arranged in a side area close to the first side frame 500 and the lower frame 400, then the connection point close to the upper frame 300 and away from the first side frame 500 (left side frame) can be selected on the radiation accessory 100 as the first target feeding point.
[0056] In one embodiment, a camera module is provided in the functional component area, and the radiation accessory is arranged around the camera module as a metal decorative part.
[0057] It is understandable that in order to improve the photography function, the existing electronic devices have introduced more and more cameras. At the same time, in order to meet the industrial design (ID) requirements of electronic devices, large metal decorative parts are usually added to the camera module to make the designed electronic devices more aesthetically pleasing and improve brand recognition. However, with the introduction of large metal decorative parts, their inherent shielding characteristics of radio waves will affect the radiation efficiency of the surrounding frame antenna and reduce the working performance of the antenna. Therefore, in this embodiment, the decorative part body of the camera module is distributed on the back shell of the electronic device as a radiation accessory, so as to meet the transmission and reception of the first frequency band signal with sufficient radiation length of the decorative part, thereby ensuring the communication performance of the radiation accessory.
[0058] In one embodiment, in conjunction with reference Figure 2 and Figure 5 The switch switching module includes: a first switch unit 210 and a second switch unit 220. The first switch unit 210 includes a first end and a plurality of second ends. The first end of the first switch unit 210 is connected to the first feed source S1. The second ends of the first switch unit 210 are connected to the first feed points one by one. The first feed points are at least partially connected points that can be conductively connected to the first feed source S1. The second switch unit 220 includes a first end and a plurality of second ends. The first end of the second switch unit 220 is connected to the metal floor G1. The second ends of the second switch unit 220 are connected to the grounding points one by one. The grounding points are at least partially connected points that can be conductively connected to the metal floor G1.
[0059] Among them, the electronic device is based on the recognition of the holding scene. When it is recognized that the current holding direction of the electronic device is vertical holding along the second direction Y, the first switch unit 210 switches the feeding path, so that the second end of the first switch unit 210 is connected to the connection point on the radiation accessory 100 corresponding to the vertical holding, and is connected to the first feed source S1 through the first end of the first switch unit 210, thereby automatically switching to the corresponding first target feeding point in the vertical screen mode of the electronic device. At the same time, the second switch unit 220 switches the grounding path, so that the second end of the second switch unit 220 is connected to the connection point on the radiation accessory 100 corresponding to the vertical holding, and is connected to the metal floor G1 through the first end of the second switch unit 220, thereby automatically switching to the corresponding target grounding point in the vertical screen mode of the electronic device.
[0060] When it is identified that the holding direction of the current electronic device is horizontally held along the first direction, the first switch unit 210 is used to switch the feeding path so that the second end of the first switch unit 210 is connected to the connection point on the radiation accessory 100 corresponding to the horizontal holding, and is connected to the first feed source S1 through the first end of the first switch unit 210, thereby automatically switching to the corresponding first target feeding point in the horizontal screen mode of the electronic device. At the same time, the second switch unit 220 switches the grounding path so that the second end of the second switch unit 220 is connected to the connection point on the radiation accessory 100 corresponding to the horizontal holding, and is connected to the metal floor G1 through the first end of the second switch unit 220, thereby automatically switching to the corresponding target grounding point in the horizontal screen mode of the electronic device. Based on this, the first target feeding point and the target grounding point on the radiation accessory 100 are selected and switched respectively by the first switch unit 210 and the second switch unit 220 to improve the antenna communication performance in different holding posture scenarios of the electronic device.
[0061] Optionally, the first switch unit 210 and the second switch unit 220 may be single-pole multiple-throw (SPNT, N is greater than or equal to 1) switches, such as Figure 8 As shown, Figure 8 Taking the four connection points at positions 1 to 4 on the radiation accessory 100 as grounding points as an example, the second switch unit 220 connects the connection point used as the target grounding point with the metal floor G1 according to the indication of the holding direction of the electronic device, and the use of a single-pole multi-throw switch as the switch unit can minimize the number of switches to reduce costs.
[0062] In one embodiment, continue to combine reference Figure 2 and Figure 5 The electronic device further includes: an impedance matching unit 800 , which is disposed between the second switch unit 220 and the metal floor G1 and is used to adjust the input impedance of the radiation accessory 100 .
[0063] Among them, input impedance refers to the ratio of voltage to current at the input end of the radiation accessory 100. Adjusting the input impedance of the radiation accessory 100 can be understood as, on the one hand, adjusting the radiation frequency band to match the target frequency band corresponding to the input feed signal so that the radiation accessory 100 radiates the signal of the target frequency band; on the other hand, the electromagnetic interference signal can be filtered out to ensure the normal operation of the radiation accessory 100.
[0064] Optionally, the impedance matching unit 800 may include at least one or more combinations of capacitors, inductors and resistors to achieve an equivalent open circuit or short circuit effect of the grounding point on the target frequency band, wherein the equivalent open circuit can be understood as the connection points of the radiation accessory 100 that are not connected to the metal floor G1 and are in a suspended state under the excitation of the target frequency band, and the equivalent short circuit can be understood as the connection points of the radiation accessory 100 that are connected to the metal floor G1 and are used as grounding points under the excitation of the target frequency band.
[0065] In one embodiment, Fig. 9 As shown, at least some of the connection points of the radiation accessory 100 can be conductively connected to the second feed source S2 to receive the feed signal input by the second feed source S2, wherein when at least some of the connection points that can be conductively connected to the second feed source S2 are conductively connected to the second feed source S2, the electronic device supports the transmission and reception of different second frequency band signals, and the second frequency band signals include low frequency band signals and medium and high frequency band signals. It should be noted that Fig. 9 It is shown that position 1 and position 4 can be connected to the second feed source S2, but the connection points at other positions can also be connected to the second feed source S2. The specific connection situation should be determined according to the actual working frequency band.
[0066] Among them, some connection points on the radiation accessory 100 serve as the second feeding points of the low frequency band (Low band, LB), the middle frequency band (Middleband, MB) and the high frequency band (High band, HB). By switching the position of the second feeding point, the radiation accessory can be flexibly controlled to switch the working frequency band, thereby realizing the reasonable use of the space of the metal decorative parts to cover more communication frequency bands. Exemplarily, the connection point on the radiation accessory 100 close to the first side frame 500 and at position 1 can be used as the feeding point of the low frequency band, and the connection point at position 4 can be used as the feeding point of the middle and high frequency bands, and the connection point at position 2 can be used as the grounding point, thereby realizing multi-band coverage of the radiation accessory 100. In addition, considering the frequency band distribution of adjacent antennas, the co-channel interference with adjacent antennas can be reduced by increasing the spatial distance, or the connection points of position 2 and position 5 can be selected as the feeding points for the second frequency band signal. That is, the implementation of the low frequency band requires longer radiating accessories, while the implementation of the high frequency band requires shorter radiating accessories. Then, the working sizes of antennas of different frequencies can be controlled by controlling the positions of the feeding points and the grounding points, or by increasing the number of grounding points.
[0067] Optionally, the low-frequency band signal includes a frequency range of 700MHz to 960MHz, the mid-frequency band signal includes a frequency range of 1710MHz to 2170MHz, and the high-frequency band signal includes a frequency range of 2300MHz to 2690MHz. Exemplarily, the mid-frequency band signal range may include 4G intermediate frequency signals (e.g., B1, B3, B39, etc.), 5G intermediate frequency signals (e.g., N1, N3, N39, etc.), and the high-frequency band signal range may include 4G high-frequency signals (e.g., B40, B41, B7, etc.), 5G high-frequency signals (e.g., N40, N41, N7, etc.) and WiFi 2.4G signals.
[0068] In one embodiment, Fig. 9 As shown, the switch switching module also includes: a plurality of third switch units 230, the first ends of the plurality of third switch units 230 are respectively connected to the second feeding point correspondingly, and the second feeding point is at least a partial connection point that can be conductively connected to the second feed source S2. The electronic device also includes: a plurality of tuning units 240, the first ends of the plurality of tuning units 240 are respectively connected to the second ends of the plurality of third switch units 230 correspondingly, and the second ends of the plurality of tuning units 240 are respectively connected to the second feed source S2. Among them, the third switch unit 230 is used to switch the connection between the conductive second feeding point and the corresponding tuning unit 240, so that the tuning unit 240 tunes the target frequency band signal, and the target frequency band signal is one of the second frequency band signals. It should be noted that, Fig. 9 The connection points shown at position 1 and position 4 are used as second feed points.
[0069] It can be understood that a third switching unit 230 and a tuning unit 240 are correspondingly set for each second feeding point, wherein, if the current electronic device needs to operate in a target frequency band, and the target frequency band corresponds to the position of a second feeding point on the radiation accessory 100, then the feeding signal input by the second feed source S2 is adjusted by the resonant frequency of the tuning unit 240 corresponding to the second feeding point, and then fed into the radiation accessory 100 from the second feeding point, so that the radiation accessory 100 supports the reception and transmission of the current target frequency band signal. Exemplarily, when the target frequency band is a low frequency band, the signal fed by the second feed source S2 is finally input to the connection point at position 1, and the connection point at position 2 is used as a grounding point to be connected to the metal floor, so that the radiation accessory 100 radiates low frequency band signals, and when the target frequency band is a medium or high frequency band, the signal fed by the second feed source S2 is finally input to the connection point at position 4, and the connection point at position 2 is used as a grounding point to be connected to the metal floor, so that the radiation accessory 100 radiates medium or high frequency band signals. Therefore, by selectively turning on each third switch unit 230, the radiation accessory 100 performs aperture tuning and frequency band switching according to different second frequency bands, thereby enabling the radiation accessory 100 to operate in different resonant frequency bands. Optionally, the tuning component in the tuning unit 240 may include devices such as capacitors or inductors to adjust the resonant frequency of the radiation accessory 100 according to the target frequency band.
[0070] In one embodiment, continue to refer to Fig. 9 , the electronic device also includes an antenna unit ANT0 formed on the first side frame 500, the antenna unit ANT0 is used to support the transmission and reception of mid-frequency band signals, and the positive projection area of the radiation accessory 100 on the back shell of the electronic device covers part of the antenna unit ANT0. The electronic device also includes: a combiner, the two first ends of the combiner are respectively connected to the feeding point of the antenna unit ANT0 and the second target feeding point, the second end of the combiner is connected to the target switch unit, the target switch unit corresponds to the target tuning unit 240, the target switch unit is any one of the multiple third switch units 230, the target tuning unit 240 is a tuning unit 240 for tuning the mid-frequency band signal, and the second target feeding point is any one of the multiple second feeding points. Wherein, when the target switch unit conducts the connection between the combiner and the target switch unit, the radiation accessory 100 supports the transmission and reception of mid-frequency band signals, and the antenna unit ANT0 supports the transmission and reception of high-frequency band signals.
[0071] It is understandable that some existing large metal decorative parts will be directly set in the area close to the left side frame of the electronic device, and will even completely block the branches of the left side frame, resulting in that the part of the left side frame covered by the projection area of the large metal decorative parts cannot be used to design the antenna structure, making the antenna layout space more tight. For example, the first side frame (which can be understood as the left side frame) of this embodiment is designed with an antenna unit ANT0, and the antenna unit ANT0 can be understood as a metal middle frame antenna, and it supports the transmission and reception of medium and high frequency band signals. However, if the radiation accessory 100 has a certain shielding on the frame at the antenna unit ANT0, that is, the radiation accessory 100 covers at least part of the antenna unit ANT0 in the vertical projection area of the back shell, the performance of the antenna unit ANT0 will deteriorate sharply, and under the shielding of the radiation accessory 100, since the loop length required for the mid-frequency band antenna is greater than that of the high-frequency band, the antenna unit ANT0 is difficult to meet the working performance in the mid-frequency band (such as B1, B3, etc.), but still has good radiation performance in the high frequency band (such as B40, B41, etc.).
[0072] Based on this, the second target feeding point on the radiation accessory 100 for transmitting and receiving mid-frequency band signals is combined with the feeding point of the antenna unit ANT0 through a combiner. When the mid-frequency band signal is input, the target switch unit is turned on so that the target tuning unit 240 tunes the input feed signal and feeds the radiation accessory 100 from the second target feeding point, so that the radiation accessory 100 supports the transmission and reception of mid-frequency band signals. When the high-frequency band signal is input, the target switch unit is turned on so that the feed signal is fed from the feeding point of the antenna unit ANT0, so that the antenna unit ANT0 supports the transmission and reception of high-frequency band signals, that is, the radiation accessory 100 and the antenna unit ANT0 complement each other's working frequency bands and jointly achieve communication performance in the mid- and high-frequency bands, effectively solving the problem of insufficient performance and incomplete frequency band coverage of the antenna unit ANT0 of the side frame in the complex environment of the electronic equipment, and avoiding the same-frequency interference between the radiation accessory 100 and the antenna unit ANT0.
[0073] In one embodiment, the electronic device further comprises: a plurality of first connectors and a plurality of second connectors, wherein one end of each of the first connectors is connected to each of the feeding points, and the other end of each of the first connectors is connected to the switch switching module. One end of each of the second connectors is connected to each of the grounding points, and the other end of each of the second connectors is connected to the switch switching module.
[0074] The first connector is used to establish an electrical connection between the feed point on the radiation accessory and the switch switching module, and the second connector is used to establish an electrical connection between the ground point on the radiation accessory and the switch switching module. Optionally, the first connector and the second connector can be elastic structures or metal contacts, such as metal springs or spring pins. For example, if metal springs are used as the first connector and the second connector, they can be connected to the radiation accessory by pressing the springs to improve electrical contact performance. In addition, the method of electrical connection using elastic connectors is also conducive to saving the space occupied by the antenna assembly in the electronic device to improve space utilization.
[0075] In one embodiment, Fig.10 As shown, a communication control method is provided, which is applied to an electronic device and includes steps S102 to S104.
[0076] Step S102: Acquire the holding direction of the electronic device.
[0077] Optionally, the holding direction of the electronic device can be detected by using sensors such as a gyroscope or an electronic compass built into the electronic device, or the holding scene of the electronic device can be identified using sensing elements on the frame of the electronic device, thereby providing accurate detection results.
[0078] Step S104: Determine the first target feeding point and the target grounding point according to the holding direction, and control the switch switching module to switch on the connection between the first feed source and the first target feeding point, and to switch on the connection between the metal floor and the target grounding point, so that the radiation accessory is stimulated to generate a radiation field corresponding to the holding direction.
[0079] Among them, the radiating accessory has a plurality of connection points arranged at intervals, at least some of the connection points can be conductively connected to the first feed source to receive the feed signal input by the first feed source, at least some of the connection points can be conductively connected to the metal floor, the two first ends of the switch switching module are respectively connected to the first feed source and the metal floor, the multiple second ends of the switch switching module are respectively connected to the multiple connection points, the first target feeding point is one of the at least some of the connection points that can be conductively connected to the first feed source, and the target grounding point is at least one of the at least some of the connection points that can be conductively connected to the metal floor.

[0081] The communication control method provided in this embodiment determines the positions of the first target feeding point and the target grounding point based on the holding direction of the electronic device. The switch switching module correspondingly switches on the connection between the first target feeding point and the first feed source, and switches on the connection between the target grounding point and the metal floor, so that the radiation accessory is stimulated to generate a current distribution and a current path corresponding to the holding direction, and then generates a radiation field corresponding to the holding direction, so as to adapt to the reception and radiation of radio waves in different holding scenarios, thereby improving the communication performance of the electronic device in different holding scenarios.
[0082] In one embodiment, a communication control device is provided, which is applied to an electronic device, wherein the control device is used to obtain a holding direction of the electronic device, determine a first target feeding point and a target grounding point according to the holding direction, and control a switch switching module to switch on a connection between a first feed source and a first target feeding point, and to switch on a connection between a metal floor and a target grounding point, so that a radiation accessory is stimulated to generate a radiation field corresponding to the holding direction.
[0083] Among them, the radiating accessory has a plurality of connection points arranged at intervals, at least some of the connection points can be conductively connected to the first feed source to receive the feed signal input by the first feed source, at least some of the connection points can be conductively connected to the metal floor, the two first ends of the switch switching module are respectively connected to the first feed source and the metal floor, the multiple second ends of the switch switching module are respectively connected to the multiple connection points, the first target feeding point is one of the at least some of the connection points that can be conductively connected to the first feed source, and the target grounding point is at least one of the at least some of the connection points that can be conductively connected to the metal floor.
[0084] Therefore, the communication control device provided in this embodiment can determine the positions of the first target feeding point and the target grounding point based on the holding direction of the electronic device, and timely adjust the functions of each connection point on the radiating accessory through the switch switching module, so that the radiating accessory generates a radiation field range corresponding to the holding direction, thereby improving the radiation efficiency and RF performance of the radiating accessory in different holding scenarios.
