Detailed Description

In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Examples of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein.

The new air interface NR technology introduced by the fifth generation mobile communication (5th Generation Mobile Networks,5G) provides more available frequency bands and greater bandwidth for wireless communication, so that extremely high data throughput can be provided. However, due to high construction cost of the 5G base station, coverage breadth and depth of the current 5G service are insufficient, and particularly in small and medium cities and remote mountain areas, a large number of 5G service blind spots exist, so that continuity of 5G signals is poor, and user experience is affected.

In order to solve the above problem, one way is to use 4G LTE and 5G NR to establish Dual Connectivity (DC), which is also called evolved universal mobile telecommunications system terrestrial Radio access network and New air interface Dual Connectivity (E-UTRA New Radio-Dual Connectivity, EN-DC). The EN-DC can realize the rapid deployment of the 5G base station based on the existing 4G core network, and further realize comprehensive network coverage through the combined networking of 4G and 5G, thereby improving the wireless resource utilization rate of the whole network system, reducing the system switching time delay and improving the user and system performance. The dual low frequency EN-DC based on gold frequency bands 800M and 700M is an excellent networking mode for operators to realize 5G rapid deployment and enhance uplink coverage. Dual low frequency EN-DC requires a User Equipment (UE) to have at least two low frequency antennas, which are respectively used as a transmitting and a main set receiving antenna of a 4G low frequency band and a 5G low frequency band, and if more optimization of dual low frequency EN-DC performance is pursued, for example, diversity reception is achieved by using independent antennas, at least three low frequency antennas need to be provided. The other mode is to fully utilize the 5G low frequency band (such as N28 frequency band) and combine the multi-antenna design to realize the multi-path receiving of the 5G low frequency band at the UE side, thereby improving the frequency spectrum utilization rate and the network capacity.

Both the above solutions require that multiple low frequency antennas are simultaneously set inside the UE, so as to maximally improve the communication performance of the dual low frequency EN-DC and 5G low frequency bands. However, with the introduction of 5G frequency bands, it is also necessary to support short-distance communication frequency bands such as Wi-Fi, bluetooth, near field communication (Near Filed Communication, NFC) and related frequency bands of global navigation satellite system (Global Navigation Satellite System, GNSS) while being compatible with the original 4G frequency bands, so how to design a multi-antenna system capable of meeting the communication performance requirements of each frequency band in a limited internal space of the electronic device is very challenging.

Referring to fig. 1, an embodiment of the present application provides an electronic device 100 including a housing assembly 110. The housing assembly 110 includes oppositely disposed first and second long sides 111, 113 and oppositely disposed first and second short sides 115, 117. The first long side 111, the first short side 115, the second long side 113 and the second short side 117 are sequentially connected to form a rounded rectangular structure. It can be appreciated that the electronic device 100 provided in the embodiments of the present application may be an electronic device with a wireless communication function, such as a smart phone, a tablet computer, a notebook computer, or an intelligent wearable device. It should be noted that the viewing angle shown in fig. 1 is a rear viewing angle of the electronic device.

In one embodiment, the electronic device 100 may include a first antenna radiator 120, a second antenna radiator 130, a third antenna radiator 140, and a fourth antenna radiator 150. Wherein the first antenna radiator 120 is disposed on the first long side 111; the second antenna radiator 130 is spaced from the first antenna radiator, and a part of the second antenna radiator 130 is disposed on the first long side 111 and another part is disposed on the first short side 115; a third antenna radiator 140 disposed on the second long side 113; the fourth antenna radiator 150 is spaced apart from the second antenna radiator 130 and the third antenna radiator 140, and a part of the fourth antenna radiator 150 is disposed on the first short side 115 and another part is disposed on the second long side 113.

In one implementation, the electronic device 100 further includes a first feed F1, a second feed F2, a third feed F3, and a fourth feed F4. The first antenna radiator 120 is provided with a first low frequency feed point 122 and a first ground point 123. The first low frequency feed point 122 is arranged at a side of the first ground point 123 facing away from the second antenna radiator 130. The first feed F1 is connected to the first low frequency feed point 122 for feeding the excitation signal of the first low frequency band to the first antenna radiator 120. The first ground point 123 is grounded. The second antenna radiator 130 is provided with a second low frequency feed point 132 and a first matching point 133. The second low frequency feeding point 132 is disposed at a side of the first matching point 133 near the first antenna radiator 120. The second feed F2 is connected to the second low frequency feed point 132 for feeding the excitation signal of the first low frequency band to the second antenna radiator 130. The electronic device further includes a first matching circuit M1, and the first matching point 133 is grounded through the first matching circuit M1. The third antenna radiator 140 is provided with a third low frequency feed point 142 and a second ground point 143. The third low frequency feed point 142 is disposed on a side of the second ground point 143 facing away from the fourth antenna radiator 150. The third feed F3 is connected to the third low frequency feed point 142 for feeding the excitation signal of the first low frequency band to the third antenna radiator 140. The second ground point 143 is grounded. The fourth antenna radiator 150 is provided with a fourth low-frequency feeding point 152 and a third grounding point 153, and the fourth low-frequency feeding point 152 is disposed on a side of the third grounding point 153 close to the third antenna radiator 140. The fourth feed F4 is connected to the fourth low frequency feed point 152 for feeding the excitation signal of the first low frequency band to the fourth antenna radiator 150. The third ground point 153 is grounded. It will be appreciated that the first feed F1, the second feed F2, the third feed F3 and the fourth feed F4 may be used to feed excitation signals of the second low frequency band to the respective connected radiators in addition to the excitation signals of the first low frequency band to the respective connected radiators.

Wherein the first, second, third and fourth antenna radiators 120, 130, 140 and 150 are configured to support four-way reception of the first low frequency signal, and at least three of the first, second, third and fourth antenna radiators 120, 130, 140 and 150 are configured to support EN-DC dual connection of the first and second low frequency signals. In one embodiment, the first low-frequency signal may be a signal in an N28 frequency band of 5G NR, and the second low-frequency signal may be a signal in a B20 frequency band of 4G LTE, so as to implement four-way reception of the signal in the N28 frequency band, and implement EN-DC in both the N28 and B20 low-frequency bands. Of course, the first low frequency signal and the second low frequency signal are not limited to the combination of N28 and B20, but may be the combination of N8 and B20, or the combination of N5 and B28, or the like.

Referring to fig. 2, in one embodiment, at least one of the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140, and the fourth antenna radiator 150 is further configured to support transmission of the first low frequency signal. For example, the radiator having the highest radiation efficiency among the first, second, third and fourth antenna radiators 120, 130, 140 and 150 is configured as a radiator supporting the emission of the first low frequency signal. It will be appreciated that the electronic device 100 may determine the most efficient radiator by measuring the transmit power and the back-off power of each antenna radiator and comparing them to each other. In this way, the radiator with the optimal performance can be selected from the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140 and the fourth antenna radiator 150 to transmit the first low-frequency signal, so that intelligent switching of the first low-frequency signal among four low-frequency antennas is realized, and the low-frequency transmission performance of the electronic device 100 is ensured.

Taking the first low frequency signal as an N28 band signal as an example, each of the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140, and the fourth antenna radiator 150 may be configured to support reception of the N28 band signal; one or both of the first, second, third and fourth antenna radiators 120, 130, 140 and 150, which are more radiation efficient, may also be configured to support the transmission of N28 band signals. Thus, four paths of receiving and at least one path of transmitting of the N28 band signal can be realized on the electronic device 100. By configuring the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140 and the fourth antenna radiator 150 to support the reception of the N28 band signal, compared with the conventional two-antenna reception scheme, the method has a further coverage range, a better weak field coverage (indoor, offshore, mountain forest, etc.), a higher downlink rate, and greatly improves the spectrum utilization rate and the network system capacity of the 5G NR low frequency band.

It will be appreciated that based on the layout of the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140 and the fourth antenna radiator 150, based on the back view setting, the fourth antenna radiator 150 will typically be held for right-handed users, where the radiation performance of the antenna radiator is necessarily affected, and the transmitting antenna radiator of the first low frequency signal may also be switched only among the first antenna radiator 120, the second antenna radiator 130 and the third antenna radiator 140 in order to avoid unnecessary switching logic. Accordingly, if left-handed, the transmitting antenna radiator of the first low frequency signal may be switched only between the first antenna radiator 120, the third antenna radiator 140 and the fourth antenna radiator 150. It can be appreciated that since the layout of the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140 and the fourth antenna radiator 150 covers two long sides and one short side of the electronic device, at least one antenna radiator is not shielded in either a horizontal screen state or a vertical screen state, thereby ensuring the stability of transmitting and receiving signals in a low frequency band.

In one embodiment, when electronic device 100 is configured to support ENDC dual connectivity of a first low frequency signal and a second low frequency signal, one of first antenna radiator 120, second antenna radiator 130, third antenna radiator 140, and fourth antenna radiator 150 is configured to support transmission and main set reception of the first low frequency signal, and the other is configured to support transmission and main set reception of the second low frequency signal. One of the remaining two antenna radiators of the first, second, third and fourth antenna radiators 120, 130, 140 and 150 is configured to support diversity reception of the first and second low frequency signals simultaneously; alternatively, one of the remaining two antenna radiators is configured to support diversity reception of the first low frequency signal, and the other is configured to support diversity reception of the second low frequency signal.

Taking the first low frequency signal as the N28 band signal and the second low frequency signal as the B20 band signal as an example, when the electronic device 100 is configured to support ENDC dual connectivity of the first low frequency signal and the second low frequency signal, the second antenna radiator 130 may be configured to support transmission and main set reception of the N28 band signal, the third antenna radiator 140 may be configured to support transmission and main set reception of the B20 band signal, and the fourth antenna radiator 150 may be configured to support diversity reception of both the N28 band signal and the B20 band signal. Therefore, three radiators with higher radiation efficiency can be selected to realize the three antennas EN-DC of the N28 frequency band and the B20 frequency band. Of course, diversity reception of the N28 band signal and the B20 band signal may also be implemented by two antenna radiators, respectively, such as the fourth antenna radiator 150 configured to support diversity reception of the N28 band signal and the first antenna radiator 120 configured to support diversity reception of the B20 band signal. It will be appreciated that the radiators supporting the transmission and main set reception of the first low frequency signal and the radiators supporting the transmission and main set reception of the second low frequency signal are configured to be switchable between the first antenna radiator 120, the second antenna radiator 130, the third antenna radiator 140 and the fourth antenna radiator 150. For example, a radiator with higher radiation efficiency can be selected to support the transmission and main set reception of the first low frequency signal and the second low frequency signal, so as to ensure better transmission performance in the low frequency band.

It can be appreciated that the electronic device 100 according to the embodiment of the present application may be a smart phone with a metal frame, at this time, the first antenna radiator 120 to the seventh antenna radiator 180 may be formed by the metal frame of the electronic device 100, a gap is formed between two adjacent radiators, and a non-conductive material may be filled in the gap to ensure the complete appearance and structural requirement of the frame. Of course, the electronic device 100 may also be a smart phone with a plastic frame, and in this case, the first antenna radiator 120 to the seventh antenna radiator 180 may be formed by a flexible circuit board (Flexible Printed Circuit, FPC) or may be formed by a direct printing structure (Printing Direct Structure, PDS) process from low-temperature conductive silver paste.

In one embodiment, the portion of the fifth antenna radiator 160 facing the first antenna radiator 120 is configured as a first medium-high frequency radiator.

Thus, 2 x 2mimo transmission and 4 x 4mimo reception of the N41 band signal can be achieved. It can be understood that, to ensure the emission performance of the N41 band signal, two radiators with higher radiation efficiency may be selected from the first middle-high frequency radiator, the second middle-high frequency radiator, the third middle-high frequency radiator and the fourth middle-high frequency radiator to support the emission and the main set connection, the MIMO emission and the main set MIMO reception of the N41 band signal respectively.

Meanwhile, the eighth antenna radiator 191 is arranged at the top area of the electronic device, so that the hand holding influence in the vertical screen state can be reduced.

In one implementation, the electronic device 100 further includes a ninth feed F9, a tenth feed F10, and an eleventh feed F11. The first antenna radiator 120 is also provided with a first uhf feed point 124. The first uhf feeding point 124 is disposed on a side of the first low-frequency feeding point 122 near the fifth antenna radiator 160, and the ninth feeding source F9 is connected to the first uhf feeding point 124 and is used for feeding an excitation signal in the uhf band to the first antenna radiator 120. The sixth antenna radiator 170 is further provided with a second uhf feed point 175, the second uhf feed point 175 being arranged at a side of the fifth ground point 174 facing away from the fourth ground point 173.

Wherein the first antenna radiator 120, the sixth antenna radiator 170, the seventh antenna radiator 180, and the eighth antenna radiator 191 are configured to support transmission and/or reception of ultra-high frequency band signals. In one embodiment, the portion of the sixth antenna radiator 170 facing the fifth antenna radiator 160 is configured as a first ultra-high frequency radiator. The first uhf radiator includes at least a portion of the sixth antenna radiator 170 on the side of the fourth ground point 173 near the fifth antenna radiator 160. The portion of the seventh antenna radiator 180 facing the third antenna radiator 140 is configured as a second ultrahigh frequency radiator.

The fourth uhf radiator includes at least a portion of the sixth antenna radiator 170 where the second uhf feed point 175 faces the seventh antenna radiator 180 side. The eighth antenna radiator 191 is configured as a fifth ultrahigh frequency radiator.

Referring to fig. 6, in one embodiment, an excitation signal of an uhf band, which is originally fed from an eighth feed F8 to a seventh antenna radiator 180, is separated from the eighth feed F8 into an uhf feed F8', a third uhf feed point 144 is provided on the third antenna radiator 140, and the separated uhf feed F8' is connected to the third uhf feed point 144 to realize a co-radiator of the uhf band and the low band.

The second uhf radiator includes at least a portion of the third antenna radiator 140 on a side of the third uhf feed point 144 near the seventh antenna radiator 180. By separating the excitation signal of the uhf band from the eighth feed F8 and feeding the excitation signal to the third antenna radiator 140 to support transmission and/or reception of the uhf band signal, simultaneous feeding of the excitation signal of the uhf band and the excitation signal of the uhf band on the same radiator can be avoided, thereby reducing the interaction between the uhf band and improving the radiation performance of the uhf band and the uhf band.

Referring to fig. 7, in one embodiment, the first, second, third, and fourth uhf radiators are configured to support transmission and/or reception of the first uhf signal; the first, second, third and fifth uhf radiators are configured to support transmission and/or reception of the second uhf signal. For example, the first ultrahigh frequency signal may be an N77/N78 band signal of NR, and the second ultrahigh frequency signal may be an N79 band signal of NR.

Any two of the first, second, third and fourth uhf radiators are configured to support transmission and main set reception of the first uhf signal, and the remaining two are configured to support diversity reception of the first uhf signal. In one embodiment, the radiators supporting the emission and main set reception of the first uhf signal are configured to be switchable between the first uhf radiator, the second uhf radiator, the third uhf radiator and the fourth uhf radiator.

Taking the N77/N78 band signal of NR as an example, the first uhf radiator may be configured to support transmission and main set reception of the N77/N78 band signal, the second uhf radiator may be configured to support MIMO transmission and main set MIMO reception of the N77/N78 band signal, the third uhf radiator may be configured to support diversity reception of the N77/N78 band signal, and the fourth uhf radiator may be configured to support diversity MIMO reception of the N77/N78 band signal. Thus, 2 x 2MIMO transmission and 4 x 4MIMO reception of the N77/N78 frequency band signals can be realized. It can be understood that, to ensure the emission performance of the N77/N78 band signal, two radiators with higher radiation efficiency can be selected from the first, second, third and fourth uhf radiators to support the emission and main set reception, MIMO emission and main set MIMO reception of the N77/N78 band signal, respectively.

Likewise, any two of the first, second, third, and fifth uhf radiators are configured to support transmission and primary set reception of the second uhf signal, and the remaining two are configured to support diversity reception of the second uhf signal. The radiator supporting the transmission of the second uhf signal and the main set reception is configured to be switchable between the first uhf radiator, the second uhf radiator, the third uhf radiator and the fifth uhf radiator. It will be appreciated that, for the specific implementation of the second uhf signal, reference may be made to the description of the embodiment of the first uhf signal, which is omitted here.

Based on the above embodiments related to low frequency, medium and high frequency and ultrahigh frequency, it can be seen that, in the electronic device 100 provided in this embodiment, no matter the low frequency antenna radiator, the medium and high frequency antenna radiator and the ultrahigh frequency antenna radiator all adopt antenna layouts that at least partially encircle the electronic device 100, and the low frequency antenna radiator, the medium and high frequency antenna radiator and the ultrahigh frequency antenna radiator are integrally formed into a 360-degree encircling layout, so as to realize 360-degree coverage of signals in each frequency band, and no matter the electronic device is in a vertical screen use state or a horizontal screen use state, at least one antenna radiator in each frequency band can be ensured not to be affected by holding.

Referring to fig. 8, in one embodiment, the electronic device further includes a twelfth feed F12. The seven-antenna radiator 180 is further provided with a first short-range band feed point 185, and the first short-range band feed point 185 is disposed at a side of the third matching point 184 near the sixth antenna radiator 170. The twelfth feed F12 is connected to the first short-range band feed point 185 for feeding the excitation signal of the first short-range band to the seventh antenna radiator 180. In addition, the fourth feed F4 is further configured to feed the fourth antenna radiator 150 with an excitation signal in the first short-range band, and the eighth feed F8 is further configured to feed the seventh antenna radiator 180 with an excitation signal in the first short-range band.

In one embodiment, the portion of the fourth antenna radiator 150 facing the third antenna radiator 140 is configured as a first short-range radiator; the portion of the seventh antenna radiator 180 facing the third antenna radiator 140 is configured as a second short-range radiator; the portion of the seventh antenna radiator 180 facing the sixth antenna radiator 170 is configured as a third short-range radiator. Wherein the first short-range radiator, the second short-range radiator and the third short-range radiator are configured to support transmission and/or reception of short-range signals of the first frequency band. The first frequency band short-range signal may be a Wi-Fi 2.4G frequency band signal or a bluetooth signal. In one embodiment, any two of the first short-range radiator, the second short-range radiator, and the third short-range radiator are configured to support 2 x 2 Multiple-Input and Multiple-Output (MIMO) of the first-band short-range signal. In this way, the electronic device 100 may select two radiators with higher radiation efficiency from the first short-range radiator, the second short-range radiator and the third short-range radiator to implement 2×2mimo of Wi-Fi 2.4G band or bluetooth band signals.

Referring to fig. 9, in one embodiment, the electronic device 100 further includes a ninth antenna radiator 192 and a thirteenth feed F13. The ninth antenna radiator 192 may be a bracket antenna radiator disposed inside the electronic device 100, which may be disposed at a side inside the electronic device near a gap formed between the third antenna radiator 140 and the seventh antenna radiator 180, as shown in fig. 9; or may be disposed at a side of the electronic device 100 near a gap formed between the first antenna radiator 120 and the fifth antenna radiator 160, as shown in fig. 10. By arranging in this way that at least a portion of the ninth antenna radiator 192 is opposite to the gap formed between the peripheral antenna radiator and the ninth antenna radiator 192, the influence of the peripheral antenna radiator on the radiation performance of the ninth antenna radiator 192 can be reduced, thereby improving the radiation performance of the ninth antenna radiator 192. The thirteenth feed F13 is connected to the ninth antenna radiator 192 for feeding the excitation signal of the second short-range frequency band to the ninth antenna radiator 192. In addition, the tenth feed F10 is further configured to feed the excitation signal of the second short-range band to the sixth antenna radiator 170.

In one embodiment, the portion of the sixth antenna radiator 170 facing the seventh antenna radiator 180 is configured as a fourth short-range radiator; the ninth antenna radiator 192 is configured as a fifth short-range radiator.

Referring to fig. 11, in one embodiment, the ninth antenna radiator 192 may also be implemented by sharing the third antenna radiator 140, i.e., without additionally providing the ninth antenna radiator 192 inside the electronic device 100. For example, a second short-range band feed point 145 may be provided on the third antenna radiator 140, the second short-range band feed point 145 being provided on a side of the third low-frequency feed point 142 near the seventh antenna radiator 180. The thirteenth feed source F13 is connected to the second short-range feed point 145 for feeding the excitation signal of the second short-range band to the third antenna radiator 140. At this time, a portion of the third antenna radiator 140 facing the seventh antenna radiator 180 is configured as a fifth short-range radiator. The fourth and fifth short-range radiators are configured to support transmission and/or reception of the second frequency band short-range signal. The second frequency band short-range signal may be a Wi-Fi 5G frequency band signal or a Wi-Fi 6G frequency band signal. In one embodiment, the fourth short-range radiator and the fifth short-range radiator are configured to support 2 x 2mimo of the second frequency band short-range signal.

Referring to fig. 12, in one embodiment, based on the embodiment shown in fig. 10, short-range communication may be further implemented using the third antenna radiator 140. The electronic device 100 may further include a fourteenth feed F14, and the connection manner of the fourteenth feed F14 and the third antenna radiator 140 may refer to the thirteenth feed F13 in the embodiment of fig. 11. At this time, the portion of the third antenna radiator 140 facing the seventh antenna radiator is configured as a sixth short-range radiator, thereby implementing a Wi-Fi 5G/6G three-antenna architecture inside the electronic device 100. Further, any two of the fourth short-range radiator, the fifth short-range radiator, and the sixth short-range radiator are configured to support 2 x 2mimo supporting the second frequency band short-range signal. In this way, the electronic device 100 may select two radiators with higher radiation efficiency from the fourth short-range radiator, the fifth short-range radiator and the sixth short-range radiator to implement 2×2mimo of Wi-Fi 5G/6G band signals.

Referring to fig. 13, in one embodiment, the positions of the second antenna radiator 130 and the fourth antenna radiator 150 may be mirrored with respect to a central axis of the electronic device 100 in a length direction. The fourth antenna radiator 150 after the mirror image is located between the first antenna radiator 120 and the second antenna radiator 130. Since the second antenna radiator 130 located at the first short side 115 is longer than the third antenna radiator 140 located at the first short side 115, in the embodiment shown in fig. 1, the slot S0 between the second antenna radiator 130 and the fourth antenna radiator 150 is relatively close to the second long side 113, and the slot S0 is easily blocked by the right hand when the electronic device 100 is in the right hand holding state, thereby affecting the antenna performance of the electronic device 100 in the right hand holding state. By arranging the second antenna radiator 130 and the fourth antenna radiator 150, the slot S0 between the second antenna radiator 130 and the fourth antenna radiator 150 can be further away from the second long side 113 than in the embodiment shown in fig. 1, so as to improve the antenna performance of the electronic device 100 in the right-hand holding state.

Referring to fig. 14, in one embodiment, a slit S1 formed between the fourth antenna radiator 150 and the first antenna radiator 120 may be further disposed closer to the first short side 115 on the basis of the example shown in fig. 13. I.e. the gap S1 formed between the fourth antenna radiator 150 and the first antenna radiator 120 is closer to the first short side 115 than the gap S2 formed between the second antenna radiator 130 and the third antenna radiator 140. At this time, the original first antenna radiator 120 becomes long, and the original fourth antenna radiator 150 becomes short, which may be insufficient to achieve resonance in the low frequency band. Therefore, it is necessary to change the low frequency antenna radiator, which is originally realized by the fourth antenna radiator 150, at least partially to be realized by the first antenna radiator 120. At this time, the fourth low frequency feeding point 152 is disposed on the first radiator 120 and located at a side of the first ground point 123 facing away from the first low frequency feeding point 122, and the fourth feed F4 is connected to the first antenna radiator 120 through the fourth low frequency feeding point 152. In this embodiment, the portion of the first antenna radiator 120 facing the fourth antenna radiator 150 and the portion of the fourth antenna radiator 150 facing the first antenna radiator 120 are together configured to support transmission and/or reception of the first low frequency signal, the second low frequency signal and the first short range signal. When the electronic device 100 is in a pocket use scenario, the second short side 117 is typically oriented toward the interior of the pocket, while the first short side 115 is oriented toward the exterior of the pocket. At this time, if the slit S1 is far from the first short side 115, the slit S1 is most likely to be blocked by a pocket, thereby affecting the communication performance of the electronic device in Wi-Fi 2.4G band and bluetooth band. The electronic device 100 shown in fig. 14 can effectively improve the communication performance of Wi-Fi 2.4G band and bluetooth band of the electronic device in the pocket use scenario by setting the slot S1 closer to the first short side 115 and changing at least part of the low frequency antenna radiator originally implemented by the fourth antenna radiator 150 to be implemented by the first antenna radiator 120.

Referring to fig. 15, in one implementation, the electronic device 100 further includes a fifteenth feed F15. The five-antenna radiator 160 is further provided with a first positioning feed point 165, and the first positioning feed point 165 is disposed at a side of the fifth matching point 164 near the sixth antenna radiator 170. The fifteenth feed source F15 and the first positioning feed point 165 are used for feeding the excitation signal of the first positioning frequency band to the fifth antenna radiator 160. In addition, the twelfth feed F12 is further configured to feed the excitation signal of the second positioning frequency band to the seventh antenna radiator 180. In one embodiment, the portion of the fifth antenna radiator 160 facing the sixth antenna radiator 170 is configured to support reception of the first band location signal, and the portion of the seventh antenna radiator 180 facing the sixth antenna radiator 170 is configured to support reception of the second band location signal. The first frequency band positioning signal can be a GPS-L5 frequency band signal, and the second frequency band positioning signal can be a GPS-L1 frequency band signal. The independent GPS-L5 antenna is realized by multiplexing the fifth antenna radiator 160, so that coexistence of the GPS-L5 and four low-frequency antennas is realized, and the electronic device 100 can be perfectly compatible with low-frequency four-way reception, low-frequency three-antenna or four-antenna EN-DC and GPS-L5, so as to meet the requirements of operators in certain regions for the three antenna working modes.

Referring to fig. 16, in one embodiment, the electronic device 100 further includes a Sar sensor 101. The first, second, third, fourth and fifth matching circuits M1, M2, M3, M4, M5 each include a capacitive device C disposed on the ground paths of the second, fifth and seventh antenna radiators 130, 160, 180 for isolating the direct current signal and allowing the high frequency signal to pass through. In this way, the second antenna radiator 130, the fifth antenna radiator 160 and the seventh antenna radiator 180 may be configured as sensing branches of the Sar sensor 101, so that the Sar detection function may be incorporated in the upper left corner, the upper right corner and the lower right corner of the electronic device 10, so that on one hand, the Sar values of 6 surfaces of the electronic device 100 may be detected, and on the other hand, all the Sar hot spot areas where the mid-high band antennas exist may be covered, and further, whether the corresponding mid-high band antennas need to be power backed according to the Sar values corresponding to each hot spot area may be selected, so as to meet the human body radiation index requirement. It can be appreciated that when the radiation performance of the fourth mid-high frequency radiator corresponding to the eighth feed source F8 is poor, and the Sar value of the upper left corner antenna of the electronic device 100 is small, the second matching circuit M2 and the third matching circuit M3 may be selectively configured to form a direct ground path from the seventh antenna radiator to the reference ground of the electronic device, so that the radiation performance of the fourth mid-high frequency radiator may be improved.

According to the electronic device 100 provided by the embodiment of the application, through the design of the 360-degree surrounding type antenna, surrounding type coverage is achieved for the antenna of the low-frequency band, the medium-high-frequency band or the ultrahigh-frequency band, and the antenna radiator corresponding to each frequency band can be configured into the transmitting antenna of the corresponding frequency band by combining intelligent antenna switching, so that the communication performance under each frequency band can be improved. Meanwhile, four paths of signals in the 5G low frequency band are received, the utilization rate and the downlink rate of the 5G low frequency band are improved, meanwhile, the low-frequency three-antenna or four-antenna EN-DC is compatible, and the forced requirements of partial areas on the EN-DC due to slower deployment of 5G base stations can be well met.

A common operation mode of the electronic apparatus 100 is given with reference to fig. 17, in which the vertical screen operation mode includes a left hand grip operation mode as shown in fig. 17 (a) and a right hand grip operation mode as shown in fig. 17 (b), and the horizontal screen operation mode includes a double hand grip operation mode as shown in fig. 17 (c). It can be appreciated that, in any operation mode, the electronic device 100 provided in the embodiment of the present application can provide good antenna performance, so as to ensure stability and reliability of the wireless communication function of the electronic device.

The foregoing examples represent only a few embodiments of the present application, which are described in more detail and are not thereby to be construed as limiting the scope of the claims.
