The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 13 in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The embodiment of the application provides an electronic device 10, where the electronic device 10 may be a smart phone, a tablet computer, or other devices, and may also be a game device, an augmented reality (Augmented Reality, abbreviated as AR) device, an automobile device, a data storage device, an audio playing device, a video playing device, a notebook computer, a desktop computing device, or the like. Referring to fig. 1, fig. 1 is a schematic diagram of a first structure of an electronic device 10 according to an embodiment of the present application, where the electronic device 10 includes a frame 110, a radio frequency module 210, a first switch circuit 220, and a second switch circuit 230.
The frame 110 is a conductive structure such as, but not limited to, a metal frame, a conductive ceramic frame, for example. The frame 110 is provided with a first grounding end 111, a first feeding point 112, a first electrical connection point 113, a second electrical connection point 114, a second feeding point 115 and a second grounding end 116 which are sequentially arranged, the first grounding end 111 and the second grounding end 116 are electrically connected with a grounding system 240 to realize grounding, the grounding system 240 is a plane or structure with zero potential, and the grounding system 240 can form a common ground. The frame segment between the first ground terminal 111 and the second electrical connection point 114 may form the first radiation branch 101, the frame segment between the second ground terminal 116 and the first electrical connection point 113 forms the second radiation branch 102, and the frame segment between the second radiation branch 102 and the first radiation branch 101 may multiplex the frame segment between the first electrical connection point 113 and the second electrical connection point 114. The rf module 210 is configured to provide a first excitation signal or a second excitation signal, the rf module 210 may be electrically connected to the first feeding point 112 to provide the first excitation signal to the first radiating branch 101, and the rf module 210 may also be electrically connected to the second feeding point 115 to provide the second excitation signal to the second radiating branch 102. One end of the first switch circuit 220 is electrically connected to the first electrical connection point 113, and the other end of the first switch circuit 220 is electrically connected to the ground system 240 to realize grounding. One end of the second switch circuit 230 is electrically connected to the second electrical connection point 114, and the other end of the second switch circuit 230 is electrically connected to the ground system 240 to achieve grounding.
When the electronic device 10 is in the first control state, such that the radio frequency module 210 feeds the first excitation signal through the first feeding point 112, and both ends of the second switch circuit 230 are in the on state, the first radiating branch 101 can support the first wireless signal under the action of the first excitation signal. When the electronic device 10 is in the second control state, such that the radio frequency module 210 feeds the second excitation signal through the second feeding point 115, and both ends of the first switch circuit 220 are in the on state, the second radiating branch 102 can support the second wireless signal under the action of the second excitation signal.
It can be appreciated that please refer to fig. 2 in conjunction with fig. 1, fig. 2 is a schematic diagram of a second structure of the electronic device 10 according to the embodiment of the present application. The rf module 210 may include a signal source 211 and a third switch circuit 212, where the signal source 211 may be a rf transceiver, a rf chip, or the like. The third switch circuit 212 includes an input end a1, a first output end b1 and a second output end b2, the input end a1 is electrically connected to the signal source 211, and the first output end b1 is electrically connected to the first feeding point 112. When the electronic device 10 is in the first control state, the third switch circuit 212 may turn on the input terminal a1 and the first output terminal b1, so that the signal source 211 feeds the first excitation signal through the first feeding point 112 to excite the first radiating branch 101 to support the transceiving of the first wireless signal. When the electronic device 10 is in the second control state, the third switch circuit 212 may turn on the input terminal a1 and the second output terminal b2, so that the signal source 211 feeds the second excitation signal through the second feeding point 115 to excite the second radiating branch 102 to support the transceiving of the second wireless signal.
It can be appreciated that the rf module 210 may also include other structures, for example, referring to fig. 3, fig. 3 is a schematic diagram of a third structure of the electronic device 10 provided in the embodiment of the present application, where the rf module 210 includes a first feed 213 and a second feed 214, the first feed 213 may provide a first excitation signal, and the second feed 214 may provide a second excitation signal. When the electronic device 10 is in the first control state, the first feed 213 may be electrically connected to the first feeding point 112 and the second feed 214 is electrically disconnected from the second feeding point 115, where the first feed 213 may feed the first excitation signal to the first radiating branch 101 to excite the first radiating branch 101 to support the transceiving of the first wireless signal. When the electronic device 10 is in the second control state, the second feed 214 may be electrically connected to the second feeding point 115 and the first feed 213 is electrically disconnected from the first feeding point 112, where the second feed 214 may feed a second excitation signal to the second radiating branch 102 to excite the second radiating branch 102 to support transceiving of the second wireless signal.
It is understood that the first grounding end 111 and the second grounding end 116 can be electrically connected to the grounding system 240 through a grounding spring, a grounding pad, etc. to realize the ground return. The first grounding end 111 and the second grounding end 116 may also be electrically connected to the ground system 240 through a load circuit to achieve ground return, where the load circuit is a circuit structure with a certain impedance (it should be noted that, the impedance values of the grounding spring and the grounding pad are smaller and negligible, and the impedance value of the load circuit is greater than the impedance values of the grounding spring and the grounding pad), and the load circuit may include an indefinite number of inductance elements, capacitance elements, and resistance elements.
It will be appreciated that when the first radiating branch 101 supports the first wireless signal, both the first ground terminal 111 and the second electrical connection point 114 of the first radiating branch 101 are grounded, and the first radiating branch 101 does not form a free end (so-called free end is the end of the radiating branch that does not return to ground), so that the first radiating branch 101 does not form a radiating opening, and the first radiating branch 101 may transmit and receive the first wireless signal in the form of a slot antenna. Similarly, when the second radiating branch 102 supports the second wireless signal, the second ground 116 and the first electrical connection point 113 of the second radiating branch 102 are both grounded, the second radiating branch 102 does not form a free end, the second radiating branch 102 does not form a radiating opening, and the second radiating branch 102 can also transmit and receive the second wireless signal in the form of a slot antenna.
It can be appreciated that please refer to fig. 1 in combination with fig. 4, fig. 4 is a schematic diagram of a current distribution when the electronic device 10 of the embodiment of the present application supports the first wireless signal. The first radiating stub 101 may form a first resonant mode under the influence of a first excitation signal to support a first wireless signal. The first resonance mode may form a first excitation current I1 flowing from the first ground terminal 111 to the first feeding point 112 and from the second electrical connection point 114 to the first feeding point 112 on the first radiating stub 101.
It is appreciated that the second radiating branch 102 may also form a current distribution similar to the first resonant mode under the influence of the second excitation signal, e.g., the second radiating branch 102 may form a second resonant mode under the influence of the second excitation signal to support the second wireless signal. The second resonant mode may form a second excitation current on the second radiating stub 102 flowing from the second ground 116 to the second feed point 115 and from the first electrical connection point 113 to the second feed point 115. It should be noted that the first radiating branch 101 may also form other current distributions and other resonant modes to support the first wireless signal, and the second radiating branch 102 may also form other current distributions and other resonant modes to support the second wireless signal.
It is understood that the first excitation signal may be the same as the second excitation signal such that the first wireless signal supported by the first radiating branch 101 is the same as the second wireless signal supported by the second radiating branch 102. Of course, the first excitation signal and the second excitation signal may also be different such that the frequency ranges of the first wireless signal and the second wireless signal are not completely different, e.g., the frequency ranges of the first wireless signal and the second wireless signal are spaced apart, or the frequency ranges of the two partially intersect.
Referring to fig. 1 in combination with fig. 5 and fig. 6, fig. 5 is a schematic view of an application scenario of the electronic device 10 provided in the embodiment of the present application, and fig. 6 is a schematic view of another application scenario of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 of the present embodiment may be held by a user's hand, where the user's hand (particularly the palm portion of the user) may support wireless signals in conjunction with the first radiating branch 101 or the second radiating branch 102.
As shown in fig. 5, when the user holds the electronic device 10 with the user's hand so that the user's hand contacts the first radiating branch 101, particularly when the user holds the electronic device 10 with the user's hand so that the user's hand contacts the frame section between the first ground terminal 111 and the first electrical connection point 113, the electronic device 10 may be in the first posture, the user's hand may hold the first radiating branch 101, the user's hand may also be used as a radiating device, and the user's hand may support the first wireless signal together with the first radiating branch 101, so that the antenna performance of the first wireless signal may be improved.
As shown in fig. 6, when the user holds the electronic device 10 with the user's hand so that the user's hand contacts the second radiating branch 102, particularly when the user holds the electronic device 10 with the user's hand contacting the bezel segment between the second ground terminal 116 and the second electrical connection point 114, the electronic device 10 may be in the second posture, the user's hand may hold the second radiating branch 102, the user's hand may also be used as a radiating device, and the user's hand may support the second wireless signal together with the second radiating branch 102, so that the antenna performance of the second wireless signal may be improved.
Note that, the letter "ant1" appearing in fig. 5 means "antenna 1", and here refers to the first radiation branch 101. The letter "ant2" appearing in fig. 6 is meant to be "antenna 2", here referred to as the second radiating branch 102. Also, the view directions of fig. 5 and 6 are different from or opposite to the view directions of fig. 1 to 4, for example, fig. 5 and 6 may be front view directions of the electronic device 10 (for example, a display surface of the display screen 300 hereinafter faces a user), and fig. 1 to 4 may be rear view directions of the electronic device 10 (for example, a rear case 600 hereinafter faces a user).
It will be appreciated that when the electronic device 10 is in the second posture, the user holds the second radiating branch 102, for example, the frame section between the second ground terminal 116 and the second electrical connection point 114, and the holding state of the user may affect the radiation performance of the first radiating branch 101, so that the antenna performance of the first radiating branch 101 supporting the first wireless signal is degraded. That is, the radiation performance of the first radiation branch 101 in the first posture is superior to that in the second posture.
For example, please refer to fig. 7, fig. 7 is a schematic diagram of an antenna efficiency curve of the electronic device 10 of the present application when supporting a first wireless signal in different scenarios, and fig. 7 is a graph of a radiation efficiency curve and a system efficiency curve of the first radiation branch 101 in a free space state (when the electronic device 10 is not held by a hand of a user, and the electronic device 10 is not in the first posture or the second posture); curves L2 and L5 are a radiation efficiency curve and a system efficiency curve of the first radiation branch 101 in the first posture; the curves L3 and L6 are a radiation efficiency curve and a system efficiency curve of the first radiation branch 101 in the second posture. Comparing the curves L1 to L3, it can be seen that the radiation efficiency of the first radiation branch 101 in the first posture is higher than the radiation efficiency of the first radiation branch 101 in the free space state, and the radiation efficiency of the first radiation branch 101 in the free space state is higher than the radiation efficiency of the second radiation branch in the second posture. Thus, when the electronic device 10 is in the first posture due to the frame section contact between the hand of the user and the first grounding terminal 111 to the first electrical connection point 113, the hand of the user can promote the radiation efficiency of the first radiation branch 101 supporting the first wireless signal.
As with the first radiating branch 101, it is appreciated that when the electronic device 10 is in the first posture, the user holds the first radiating branch 101, for example, the frame section between the first ground terminal 111 and the first electrical connection point 113, and the holding state of the user may affect the radiation performance of the second radiating branch 102, so that the antenna performance of the second radiating branch 102 supporting the second wireless signal is reduced, that is, the radiation performance of the second radiating branch 102 in the second posture is better than that in the first posture.
For example, please refer to fig. 8, fig. 8 is a schematic diagram of an antenna efficiency curve of the electronic device 10 supporting the second wireless signal in a different scenario. Curves L7 and L10 in fig. 8 are radiation efficiency curves and system efficiency curves of the second radiation branch 102 in a free space state (when the electronic device 10 is not held by the user's hand, the electronic device 10 is not in the first posture or the second posture); curves L8 and L11 are radiation efficiency curves and system efficiency curves of the second radiation branch 102 in the first posture; curves L9 and L12 are the radiation efficiency curve and the system efficiency curve of the second radiation branch 102 in the second posture. Comparing the curves L7 to L9, it can be seen that the radiation efficiency of the second radiation branch 102 in the second posture is higher than the radiation efficiency of the second radiation branch 102 in the free space state, and the radiation efficiency of the second radiation branch 102 in the free space state is higher than the radiation efficiency of the first radiation branch in the first posture. Thus, when the electronic device 10 is in the second posture due to the frame segment contact between the user's hand and the second ground terminal 116 to the second electrical connection point 114, the user's hand may promote the radiation efficiency of the second radiation branch 102 supporting the second wireless signal.
It can be understood that, because the first feeding point 112 is a current strong point area of the first resonant mode, when the user hand holds the frame area corresponding to the first feeding point 112, the user hand can further improve the antenna performance of the first radiating branch 101 supporting the first wireless signal. Similarly, since the second feeding point 115 is a current strong point region of the second resonant mode, when the user hand holds the frame region corresponding to the second feeding point 115, the user hand can further improve the antenna performance of the second radiating branch 102 supporting the second wireless signal.
It can be appreciated that when the user's hand holds the frame section between the first electrical connection point 113 and the second electrical connection point 114, the user's hand can support the first wireless signal together with the first radiating branch 101 to improve the antenna performance of the first radiating branch 101, and can support the second wireless signal together with the second radiating branch 102 to improve the antenna performance of the second radiating branch 102.
In the electronic device 10 of the embodiment of the present application, when the radio frequency module 210 feeds the first excitation signal through the first feeding point 112 and both ends of the second switch circuit 230 are in the on state, the frame section between the first grounding end 111 and the second electrical connection point 114 may form the first radiating branch 101 without a break and may support the first wireless signal; when the radio frequency module 210 feeds in the second excitation signal through the second feeding point 115 and both ends of the first switch circuit 220 are in a conducting state, the frame section between the second grounding end 116 and the first electrical connection point 113 can form a second radiation branch 102 without a break seam and can support the second wireless signal, on one hand, the first radiation branch 101 and the second radiation branch 102 are not provided with break seams, the frame area between the first grounding end 111 and the second grounding end 116 is of a frame structure without break seams, the frame 110 can keep the appearance integrity, the aesthetic property of the frame 110 can be improved, and the structural strength of the frame 110 can also be improved; on the other hand, the first radiation branch 101 and the second radiation branch 102 multiplex the frame region between the first electrical connection point 113 and the second electrical connection point 114, so that the space occupied by the first radiation branch 101 and the second radiation branch 102 can be reduced, and the miniaturization design of the electronic device 10 can be realized. Moreover, since the first radiation branch 101 and the second radiation branch 102 have no fracture structure, when the first radiation branch 101 supports the first wireless signal, the user can increase the antenna performance of the first radiation branch 101 supporting the first wireless signal by holding the first radiation branch 101 by hand; when the second radiation branch 102 supports the second wireless signal, the user's hand holds the second radiation branch 102 and can also increase the antenna performance of the second radiation branch 102 supporting the second wireless signal, so that the first radiation branch 101 and the second radiation branch 102 of the present application have better hand-holding performance, compared with the scheme that the hand holds the radiation branch and deteriorates the antenna performance of the radiation branch in the related art, the present application provides a seamless antenna scheme capable of improving the hand-holding state.
Referring to fig. 9, fig. 9 is a schematic diagram of a fourth structure of the electronic device 10 according to the embodiment of the present application, and the electronic device 10 may further include a gesture detection module 250 and a control module 260.
The gesture detection module 250 is configured to detect a current gesture of the electronic device 10, which may be the first gesture or the second gesture. The first gesture is a gesture in which the hand of the user contacts the first radiation branch 101, and the second gesture is a gesture in which the hand of the user contacts the second radiation branch 102.
The control module 260 may be a processor, a processing chip, a control chip, or the like. The control module 260 is electrically connected to the rf module 210, the first switch circuit 220, the second switch circuit 230, and the gesture detection module 250, respectively. The control module 260 may control the electronic device 10 to be in a first control state when the gesture detection module 250 detects that the electronic device 10 is in the first gesture, so that the radio frequency module 210 feeds the first excitation signal through the first feeding point 112, and two ends of the second switch circuit 230 are in a conductive state (at this time, two ends of the first switch circuit 220 may be in a disconnected state or grounded through the load circuit), and the first radiating branch 101 may support the first wireless signal together with the hand of the user. The control module 260 may also control the electronic device 10 to be in a second control state when the gesture detection module 250 detects that the electronic device 10 is in the second gesture, so that the radio frequency module 210 feeds the second excitation signal through the second feeding point 115, and both ends of the first switch circuit 220 are in a conductive state (both ends of the second switch circuit 230 may be in a disconnected state or grounded through the load circuit), and the second radiating branch 102 may support the second wireless signal together with the hand of the user.
It can be appreciated that, when the electronic device 10 is in the first posture, the control module 260 can control the third switch circuit 212 of the rf module 210 to switch on the input terminal a1 and the first output terminal b1, so that the rf module 210 feeds the first excitation signal through the first feeding point 112. The control module 260 may further control the third switch circuit 212 to turn on the input terminal a1 and the second output terminal b2 when the electronic device 10 is in the second posture, so that the rf module 210 feeds the second excitation signal through the second feeding point 115.
It can be appreciated that, when the electronic device 10 is in the first posture, the control module 260 can control the first feed 213 to be electrically connected to the first feeding point 112 and control the second feed 214 to be electrically disconnected from the second feeding point 115, so that the radio frequency module 210 feeds the first excitation signal through the first feeding point 112. The control module 260 is further configured to control the second feed 214 to be electrically connected to the second feeding point 115 and control the first feed 213 to be electrically disconnected from the first feeding point 112 when the electronic device 10 is in the second posture.
It is understood that gesture detection module 250 may include, but is not limited to, at least one of a proximity sensor, a SAR value detection sensor. For example, the gesture detection module 250 may include two proximity sensors, one proximity sensor is disposed in the area where the first radiation branch 101 is located, the other proximity sensor is disposed in the area where the second radiation branch 102 is located, the proximity sensor may detect a distance between an obstacle and the electronic device 10, and may determine that the electronic device 10 is in the first gesture or the second gesture when the distance between the obstacle and the electronic device 10 is less than a preset distance threshold, and the gesture detection module 250 may comprehensively determine that the electronic device 10 is in the first gesture or the second gesture according to detection data of the two proximity sensors. For another example, the gesture detection module 250 may include two SAR value detection sensors, one SAR value detection sensor is disposed in the area where the first radiation branch 101 is located, the other SAR value detection sensor is disposed in the area where the second radiation branch 102 is located, the SAR value detection sensor may determine that the electronic device 10 is in the first gesture or the second gesture when determining that the distance between the obstacle and the electronic device 10 is smaller than the preset distance threshold according to the change of the capacitance value, and the gesture detection module 250 may comprehensively determine that the electronic device 10 is in the first gesture or the second gesture according to the detection data of the two proximity sensors.
The control module 260 of the electronic device 10 according to the embodiment of the present application may control the electronic device to be in a first control state according to the first gesture detected by the gesture detection module 250, and may also control the electronic device to be in a second control state according to the second gesture detected by the gesture detection module 250, so that the electronic device 10 of the present application may select signals corresponding to radiation branches with better radiation performance in different holding states of a user, and the holding performance of the electronic device 10 is better.
The electronic device 10 of the embodiment of the present application may also use other manners to adjust the electronic device 10 to be in the first control state or the second control state. The electronic device 10 may be in a first control state when the first radiating branch 101 supports a first wireless signal with a first radiation performance that is better than a second radiating branch 102 supports a second wireless signal; the second control state is in when the second radiation performance when the second radiation branch 102 supports the second wireless signal is better than the first radiation performance when the first radiation branch 101 supports the first wireless signal. The first radiation performance and the second radiation performance may be determined according to the first gesture and the second gesture detected by the gesture detection module 250.
For example, when the gesture detection module 250 detects that the electronic device 10 is in the first gesture where the user's hand contacts the first radiation branch 101, the first radiation performance of the first radiation branch 101 and the user's hand together supporting the first wireless signal may be better than the second radiation performance of the second radiation branch 102 supporting the second wireless signal (where the user's hand may adversely affect the second radiation branch 102) under the action of the user's hand, so the control module 260 may control the electronic device 10 to be in the first control state. When the gesture detection module 250 detects that the electronic device 10 is in the second gesture where the user's hand contacts the second radiation branch 102, the second radiation performance of the second radiation branch 102 and the user's hand together supporting the second wireless signal may be better than the first radiation performance of the first radiation branch 101 supporting the first wireless signal (the user's hand may have an adverse effect on the first radiation branch 101 at this time) under the action of the user's hand, so the control module 260 may control the electronic device 10 to be in the second control state.
It will be appreciated that the advantages of the first radiation performance and the second radiation performance may also be determined according to the antenna parameters when the first radiator branch 101 supports the first wireless signal and the antenna parameters when the second radiator branch 102 supports the second wireless signal.
For example, the electronic device 10 may be in a first control state to obtain a received signal strength (Received Signal Strength Indication, abbreviated RSSI) when the first radiating branch 101 supports the first wireless signal; the electronic device 10 may then be in a second control state to obtain an RSSI value for the second radiating branch 102 supporting the second wireless signal, compare the two RSSI values, and select the control state corresponding to the parameter having the greater RSSI value as the current control state. Thus, when the first received signal strength value of the first radiating branch 101 supporting the first wireless signal is greater than the second received signal strength value of the second radiating branch 102 supporting the second wireless signal, the electronic device 10 is in the first control state; the electronic device 10 is in the second control state when the second received signal strength value of the second radiating branch 102 supporting the second wireless signal is greater than the first received signal strength value of the first radiating branch 101 supporting the first wireless signal.
Also exemplary, the electronic device 10 may be in a first control state to obtain a reference signal received power (Reference Signal Receiving Power, RSRP for short) when the first radiating branch 101 supports the first wireless signal; the electronic device 10 may then be in a second control state to obtain an RSRP value when the second radiating branch 102 supports the second wireless signal, compare the two RSRP values, and select the control state corresponding to the parameter with the larger RSRP value as the current control state. Thus, when the first reference signal reception power value when the first radiating branch 101 supports the first wireless signal is greater than the second reference signal reception power value when the second radiating branch 102 supports the second wireless signal, the electronic device 10 is in the first control state; the electronic device 10 is in the second control state when the second reference signal reception power value when the second radiating branch 102 supports the second wireless signal is greater than the first reference signal reception power value when the first radiating branch 101 supports the first wireless signal.
Based on this, the electronic device 10 of the present application may select the control state corresponding to one of the first radiation branch 101 and the second radiation branch 102 with better radiation performance for control. It should be noted that, the electronic device 10 may also determine to execute the first control state or the second control state in other manners, which is not limited in the embodiment of the present application.
