Fig. 3 is a schematic diagram of a composition structure of a first embodiment of an electronic device in an embodiment of the present application, taking up and down folding as an example, and referring to fig. 1 and fig. 2, as shown in fig. 3, the electronic device 100 may further include a plurality of first antennas 160 (e.g., an antenna ANT1601, an antenna ANT1602, an antenna ANT1603, and an antenna ANT1604 in fig. 3) and a plurality of second antennas 180 (e.g., an antenna ANT1801, an antenna ANT1802, an antenna ANT1803, and an antenna ANT1804 in fig. 3), where the plurality of first antennas 160 are disposed in the first casing 122; a plurality of second antennas 180 are disposed on the second housing 124; when the first housing 122 and the second housing 124 are in the folded state, at least a first antenna 160 and a second antenna 180 are disposed opposite to each other, and one of the first antenna 160 and the second antenna 180 disposed opposite to each other is in the operating state, and the other antenna (which may be referred to as an antenna to be switched in the embodiment of the present application) is switched to operate other than the antenna disposed opposite to the other antenna (which may be referred to as a multiplexing antenna in the embodiment of the present application).
With the electronic device provided in the embodiment of the present application, when the electronic device 100 is in the folded state, the first antenna 160 (or the second antenna 180) of the first antenna 160 and the second antenna 180 that are oppositely disposed is switched to operate as an antenna except for the second antenna 180 (or the first antenna 160), that is, the first antenna 160 (or the second antenna 180) multiplexes an antenna except for the second antenna 180 (or the first antenna 160), so on the one hand, the function of the first antenna 160 and the function of the second antenna 180 that are oppositely disposed can still be maintained, and on the other hand, the first antenna 160 (or the second antenna 180) of the two antennas that are oppositely disposed is switched to operate as an antenna that is not oppositely disposed to the second antenna 180 (or the first antenna 160), thereby ensuring the isolation between the two antennas of the first antenna 160 and the second antenna 180 after the switching is completed, ensuring the respective radiation performance of the two antennas, and further greatly improving the communication capability of the folded electronic device.
It should be noted that fig. 3 is only an example of an electronic device folded up and down, and the electronic device provided in the embodiment of the present application may also be a type folded left and right or a type of a scroll screen. The number of antennas in fig. 3, the arrangement position in the electronic device, is only an example, and is not intended to limit the scope of the present application, and the switching operation manner of the present application may be used as long as there are oppositely arranged antennas in the folded state.
In one illustrative example, the first antenna 160 and the second antenna 180 are oppositely disposed antennas of the same frequency, wherein one antenna is a main set antenna and the other antenna is a diversity antenna.
In an exemplary embodiment, the first antenna 160 and the second antenna 180 may be partially or completely disposed opposite to each other. Partially opposed is understood to mean that the first antenna 160 is positioned on the second antenna 180 at the forward projection of the second housing 124. The diametrically opposed arrangement may be understood as the first antenna 160 and the second antenna 180 are symmetrically disposed along a centerline of the electronic device 100 when the first housing 122 and the second housing 124 are in the unfolded state.
In an illustrative example, the electronic device 100 provided in the embodiment of the present application may further include: a processing module (not shown in fig. 3) for determining antenna performance based on antennas other than the oppositely disposed first and second antennas; and determining the antenna with the best antenna performance as the multiplexing antenna and controlling the antenna to be switched to the multiplexing antenna.
In one embodiment, the processing module may be configured to:
acquiring a current application scene of the electronic equipment; according to the preset application scene and the corresponding relation of the antennas except the first antenna 160 and the second antenna 180 which are oppositely arranged, the antenna in the corresponding relation is used as a multiplexing antenna and the antenna to be switched is controlled to be switched to the multiplexing antenna. Wherein, the corresponding relation includes: the correspondence between each application scenario and the antenna other than the first antenna 160 and the second antenna 180 that are oppositely disposed for the optimal antenna performance under that application scenario.
In one embodiment, the correspondence relationship between the application scenario and the antenna other than the first antenna 160 and the second antenna 180 which are oppositely disposed is obtained through testing in advance. Such as: in the design stage, the performance of all antennas except the first antenna and the second antenna which are arranged oppositely is tested under each application scene (such as folding, single hand holding by a user, horizontal holding by the user and the like), and the corresponding relation between each application scene and the antenna with the optimal antenna performance under the application scene is established respectively, so that when the antenna needs to be switched, the corresponding antenna with the optimal antenna performance can be found from the corresponding relation to serve as a multiplexing antenna according to the application scene where the electronic equipment is located currently. It should be noted that the application scenario of the electronic device may be known through various sensors in the electronic device, and the specific implementation is not used to limit the protection scope of the present application, and is not described herein again.
In an exemplary embodiment, the multiplexing antenna may not be in the same housing as the antenna in an operating state of the oppositely disposed antennas; or,
the multiplexing antenna can be in the same shell with the antenna in the working state in the antenna which is oppositely arranged.
In an exemplary embodiment, the first antenna 160 and the second antenna 180 which are oppositely arranged may include a combination of antennas which are pre-designated to be controlled when the electronic device 100 is in the folded state after the antennas of the electronic device are designed.
In an exemplary embodiment, the antennas other than the first antenna 160 and the second antenna 180 that are oppositely disposed may be two or more antennas that are pre-selected (e.g., through testing, etc.), which may be multiplexed antennas. In an embodiment, the first antenna 160 and the second antenna 180 which are relatively arranged and need to be antenna-controlled and one antenna which can be a multiplexing antenna can be determined by testing the electronic device before leaving the factory.
In one illustrative example, the processing module is further configured to: under the condition that the electronic device 100 is in the folded state, after the antenna to be switched to the multiplexing antenna operates, the antenna to be switched that does not operate, that is, the tuning circuit of the antenna to be switched, is controlled to be switched to the branch with the worst antenna radiation performance, that is, the logic state of the antenna to be switched that does not operate, that is, the tuning circuit of the antenna to be switched, is controlled to be set in the state with the worst antenna radiation performance. In this way, the interference of the non-working antenna of the first antenna 160 and the second antenna 180 of the opposing device to the working antenna of the first antenna 160 and the second antenna 180 of the opposing device is reduced, and the communication performance of the working antenna of the first antenna 160 and the second antenna 180 of the opposing device in the folded state is improved.
In an exemplary embodiment, since the position of the antenna on the electronic device is an optimal form selected in advance through testing, the communication performance of the electronic device can be ensured by using the antenna at a reasonable position in the unfolded state of the electronic device, and therefore, when the electronic device 100 is converted from the folded state to the unfolded state, the processing module can be further configured to: and controlling the switched antenna, namely the multiplexing antenna, to switch back to the other antenna, namely the antenna to be switched, which is arranged oppositely during folding to work, thus ensuring that the antenna with the optimal antenna performance works and ensuring the communication performance of the electronic equipment.

The SPnT switch comprises a public port, a first port and at least one second port; the common port is connected to the second feed RF2, the first port is connected to the matching circuit M2, and at least one second port is connected to at least one matching circuit (e.g., the tuning circuit T3 and the tuning circuit T4 in fig. 5).
Fig. 6 is a schematic structural diagram of a fourth embodiment of an electronic device in an embodiment of the present application, where the electronic device is folded up and down as an example, and as shown in fig. 6, in the embodiment, a metal frame antenna of a mobile phone is taken as an example, an antenna 1 and an antenna 2 are a pair of a first antenna 160 and a second antenna 180 of the electronic device that are opposite to each other in a folded state, and it is assumed that the antenna 1 and the antenna 2 are co-frequency antennas, where the antenna 1 is a main set antenna and the antenna 2 is a diversity antenna. The antenna 3 is a multiplex antenna when the antenna 1 and the antenna 2 need to perform antenna control processing.

The antenna 2 is arranged at the lower left corner of the lower half part of the mobile phone, the antenna 3 is arranged at the lower right corner of the lower half part of the mobile phone, the second feed source RF2 is a signal source of the antenna 2, the second feed source RF2 passes through an SPDT switch and then is fed into the antenna 2 or the antenna 3 serving as a multiplexing antenna through the matching circuit M22 or the matching circuit M33, and the antenna 2 and the antenna 3 are grounded through the tuning circuit T22 and the tuning circuit T33 respectively. As shown in fig. 5, the common port of the SPDT switch is connected to the second feed RF2, the first port of the SPDT switch is connected to the matching circuit M22, and the second port of the SPDT switch is connected to the matching circuit M33.
When the mobile phone is in an unfolded state, the first feed source RF1 is fed into the antenna 1 through the matching circuit M11, the second feed source RF2 is fed into the antenna 2 through the matching circuit M22 after passing through the common port and the first port of the SPDT switch, namely the second feed source RF2 is connected with the antenna 2 and disconnected with the antenna 3 through the SPDT switch, and at the moment, the distance between the antenna 1 and the antenna 2 is long, so that mutual influence is hardly caused, and the mobile phone is in normal communication. When the mobile phone is in an unfolded state, the second feed source RF2 is switched to the antenna 2 through the SPDT to work, the second feed source RF2 is ensured to work by using the antenna 2 with the optimal antenna performance, and the communication performance of the mobile phone is ensured.

Meanwhile, after the antenna 2 is switched to the antenna 3 to operate, the logic state of the tuning circuit T22 is controlled to be the worst state of the antenna radiation performance of the antenna 2. Thus, the interference of the antenna 2 to the antenna 1 is reduced to the maximum extent, and the communication performance of the antenna 1 in a folded state is improved.
When the mobile phone is in a folded state, the second feed source RF2 is switched to the antenna 3 to work through the SPDT, the antenna 1 is avoided from the space, the communication performance of the second feed source RF2 is improved, and the problem that the communication performance is reduced due to poor isolation between the second feed source RF2 and the antenna 1 when the second feed source RF2 works on the antenna 2 is solved; and also. When the mobile phone is in a folded state, the logic state is placed in the worst state of the radiation performance of the antenna by controlling the tuning circuit of the antenna 2, so that the interference of the antenna 2 which does not work at the moment on the antenna 1 which is in a working state is reduced, and the communication performance of the antenna 1 in the folded state is improved.

Moreover, when the electronic device is in a folded state, the logic state of the tuning circuit of the antenna 2 is controlled to reduce the performance of the antenna 2 which does not work currently, the influence of the antenna 2 on the antenna 1 is reduced, and the communication performance of the antenna 1, namely the first feed source RF1, is improved.
