Fig. 1 is a schematic structural diagram of an electronic device 100 shown according to an exemplary embodiment, and fig. 2 is a partial schematic diagram of the electronic device 100 shown according to an exemplary embodiment. As shown in fig. 1 and 2, the electronic device 100 may include a metal bezel body 1, an antenna radiator 2, a clearance area 3, a first antenna slot 4, and a second antenna slot 5. The metal middle frame body 1 can be used as a return ground of an antenna signal, the antenna radiator 2 and the metal middle frame body 1 enclose a clearance area 3, and the clearance area 3 can be used for realizing circuit wiring.
Further, due to the presence of the first antenna slot 4 and the second antenna slot 5, the antenna radiator 2 can be divided into multiple sections. Specifically, as shown in fig. 2, the antenna radiator 2 may include a first radiator 21, a second radiator 22, and a third radiator 23, where the first radiator 21 is located between the first antenna slot 4 and the second antenna slot 5, the second radiator 22 and the third radiator 23 are both connected to the metal middle frame body 1, the first radiator 21 and the second radiator 22 are located on two sides of the first antenna slot 4, and the first radiator 21 and the third radiator 23 are located on two sides of the second antenna slot 5, respectively.
For example, as shown in fig. 2, the second radiator 22 and the first antenna slot 4 may be located on the left side of the electronic device 100, and the third radiator and the second antenna slot 5 may be located on the right side of the electronic device 100, with the display panel of the electronic device 100 facing upward. Of course, in other embodiments, the second radiator 22 and the first antenna slot 4 may be located on the right side of the electronic device 100, and the third radiator and the second antenna slot 5 may be located on the left side of the electronic device 100, which is not limited by this disclosure.
Still as shown in fig. 2, the electronic device 100 may further include a feed point 6 and a first switch circuit 7, one end of the feed point 6 is grounded, and the other end of the feed point is connected to the first radiator 21, one end of the first switch circuit 7 is connected to the second radiator 22, and the other end of the first switch circuit 7 is connected between the feed point 6 and the first radiator 21, and the first switch circuit 7 may be configured to adjust the antenna radiator 2 for radiating an antenna signal according to a holding state of the electronic device 100, so as to adapt to a current holding scenario by adjusting a shape and a length of the antenna radiator 2 currently used for radiating the signal, which is beneficial to reduce antenna performance degradation caused in different holding states, and improve antenna performance of the electronic device 100.
It should be noted that: in the embodiment shown in fig. 2, the feed point 6 is connected to the first radiator 21 at an end close to the first antenna slot 4, and the first switch circuit 7 is located near the first antenna slot 4, so that the circuit path of the second switch circuit 7 connected to the second radiator 22 can be shortened, and when the first radiator 21 and the second radiator 22 need to be connected through the first switch circuit 7, the performance loss can be reduced. In another embodiment, the feed point 6 may also be connected to an end of the first radiator 21 close to the second antenna slot 5, which is not limited by the present disclosure.
In the present embodiment, the electronic apparatus 100 may have a plurality of holding states, and according to the usage habit of the user, a state in which the electronic apparatus 100 is held by a right hand and a state in which the electronic apparatus 100 is held by a left hand may be generally included. Taking the electronic device 100 with the display panel facing upward as an example, if the right hand holds the electronic device 100, the right hand shields at least a part of the radiation area of the third radiator 23 in fig. 2, and if the left hand holds the electronic device 100, the left hand shields at least a part of the radiation area of the second radiator 22 in fig. 2.
In an embodiment, when the electronic device 100 is in the first holding state (i.e., the right-hand holding state), the on-off state of the first switch circuit 7 may be adjusted according to the frequency of the antenna signal. For example, assuming that the electronic device 100 is in the first holding state, the on-off state of the first switch circuit 7 may include an off state and an on state, if the electronic device 100 needs to radiate a high-frequency antenna signal at this time, the first switch circuit 7 may be adjusted to the off state, the antenna signal from the feed point 6 may be transmitted to the first radiator 21 and further coupled to the second radiator 22, most of the high-frequency antenna signal is radiated by the second radiator 22, and since the second radiator 22 is far away from an area blocked by the right hand of the user, the influence of the holding of the user on the antenna performance can be reduced; if the electronic device 100 needs to radiate the low-frequency antenna signal, the first switch circuit 7 may be adjusted to be in a conducting state, and at this time, the first radiator 21 and the second radiator 22 may be regarded as a whole radiation body, and most of the low-frequency antenna signal is radiated by the first radiator 21 and the second radiator 22, because the second radiator 22 is far away from the area blocked by the right hand of the user, and the end of the first radiator 21 close to the second radiator 22 is also far away from the area blocked by the right hand of the user, the influence of the user's holding on the antenna performance can be reduced. Wherein, the frequency of the low-frequency antenna signal is between 700MHz and 960MHz, and the frequency of the high-frequency antenna signal is between 2300MHz and 2690 MHz.
In another embodiment, when the electronic apparatus 100 is in the second holding state (i.e., the left-hand holding state), the on-off state of the first switch circuit 7 may be adjusted according to the frequency of the antenna signal. For example, assuming that the electronic device 100 is in the second holding state, the on-off state of the first switch circuit 7 may include an off state and an on state, if the electronic device 100 needs to radiate a high-frequency antenna signal at this time, the first switch circuit 7 may be adjusted to the on state, the antenna signal from the feed point 6 may be transmitted to the first radiator 21 and further coupled to the third radiator 23, most of the high-frequency antenna signal is radiated by the third radiator 23, and since the third radiator 23 is far away from an area blocked by the left hand of the user, the influence of the holding of the user on the antenna performance can be reduced; if the electronic device 100 needs to radiate the low-frequency antenna signal, the first switch circuit 7 may be adjusted to an off state, and the first radiator 21 and the second radiator 22 are independent from each other, so that most of the low-frequency antenna signal may be radiated mainly through the first radiator 21, and since the end of the first radiator 21 close to the third radiator 23 is also far away from the area blocked by the right hand of the user, the influence of the user's holding on the antenna performance may be reduced. Wherein, the frequency of the low-frequency antenna signal is between 700MHz and 960MHz, and the frequency of the high-frequency antenna signal is between 2300MHz and 2690 MHz.
In other words, in the present disclosure, the length and the shape of the antenna radiator 2 for radiating the antenna signal can be adjusted by the first switch circuit 7, so that the corresponding antenna radiator away from the user-shielded area can be used for radiating the corresponding antenna signal, and the influence of the user holding on the antenna performance is reduced; moreover, the antenna radiation efficiency of the electronic apparatus 100 is high in both cases of right-handed holding and left-handed holding.
It should be noted that: in the present disclosure, the antenna radiator for adjusting the radiation signal by the first switch circuit 7 is described by taking the embodiment shown in fig. 2 as an example, actually, as shown in fig. 3, the feed point 6 may be disposed near the third radiator 23, one end of the first switch circuit 7 may also be connected to the third radiator 23, and the other end is connected between the first radiator 21 and the feed point 6.
In this embodiment, when the electronic device 100 is in the right-hand holding state, if the electronic device 100 needs to radiate a low-frequency antenna signal, the first switch circuit 7 may be switched to the off state to radiate the low-frequency antenna signal through the first radiator 21; if the electronic device 100 needs to radiate a high-frequency antenna signal, the first switch circuit 7 may be switched to a conducting state, and the high-frequency antenna signal is radiated by the second radiator 22. When the electronic device 100 is in the left-handed holding state, if the electronic device 100 needs to radiate a low-frequency antenna signal, the first switch circuit 7 may be switched to the conducting state, so as to radiate the low-frequency antenna signal through the first radiator 21 and the third radiator 23 together; if the electronic device 100 needs to radiate a high-frequency antenna signal, the first switch circuit 7 may be switched to the off state, and the high-frequency antenna signal may be radiated by the third radiator 23.
Based on the above embodiments, the first switch circuit 7 may include a single-pole multi-throw switch, for example, a single-pole double-throw switch, or the first switch circuit 7 may also include a multi-pole multi-throw switch, which is not limited by the present disclosure. The above embodiments are all used to describe the state of the first switch circuit 7 when the electronic apparatus 100 radiates the high-frequency antenna signal and the low-frequency antenna signal in different small holding states. It can be understood that, the electronic device 100 needs to radiate an intermediate frequency antenna signal in addition to a high frequency antenna signal and a low frequency antenna signal, and in the technical solution of the present disclosure, when the electronic device 100 needs to radiate an intermediate frequency antenna signal, the first switch circuit 7 may be switched to the off state, so that better radiation efficiency can be ensured. The frequency of the intermediate frequency antenna signal is within 1710MHz-2170 MHz.
In the above-described embodiment, the on-off state of the first switch circuit 7 needs to be adjusted according to the holding state of the electronic apparatus 100 and the antenna signal frequency. Therefore, as shown in fig. 4, the electronic device 100 in the present disclosure may further include a status detection component, which may be used to detect the holding status of the electronic device 100. For example, the state detection component may include a gyroscope, and determine the current holding state of the electronic device 100 according to the three-axis acceleration detected by the gyroscope; or the state detection component may also include a first light sensor located on the left side of the electronic device 100 and a first light sensor located on the right side of the electronic device 100, and when the first light sensor is blocked, the electronic device may be considered to be in the left-hand holding state, and when the second light sensor is blocked, the electronic device 100 may be considered to be in the right-hand holding state. Of course, the status detection component may also detect the status of the electronic device 100 through other forms, which is not illustrated in this disclosure.
Based on the technical solution of the present disclosure, as shown in fig. 4, the electronic device 100 may further include a second switch circuit 8 and a tuning circuit 9, where one end of the second switch circuit 8 is connected to the first radiator 21, and the other end is grounded through the tuning circuit 9. In other words, the tuning circuit 9 may be connected between the first radiator 21 and the second switch circuit 8, so that the inductance, capacitance or resistance applied to the first radiator 21 may be adjusted by the second switch circuit 8, thereby tuning the antenna to cover the full frequency band of 2G, 3G, 4G.
For example, as shown in fig. 5, the tuning circuit 9 may include a plurality of tuning elements, and the plurality of tuning elements are respectively grounded, and the tuning elements may be inductors, capacitors, or resistors. To match the tuning circuit 9, the second switching circuit 8 may comprise a single-pole, multi-throw switch that may be used to adjust the tuning element in conduction with the first radiator 21. For example, as shown in fig. 5, the tuning circuit 9 may include a first tuning element 91, a second tuning element 92, a third tuning element 93 and a fourth tuning element 94, and the first tuning element 91, the second tuning element 92, the third tuning element 93 and the fourth tuning element 94 are grounded, respectively. The second switching circuit 8 may comprise a single pole four throw switch by means of which the tuning element connected to the first radiator 21 can be switched, for example the single pole four throw switch in fig. 5 connects the fourth tuning element to the first radiator 21. In other cases, the third tuning element 93, the second tuning element 92, or the first tuning element 91 may be connected to the first radiator 21 by a single-pole four-throw switch.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
