As is known, to implement the communication function of the mobile terminal, an antenna is required to be disposed on the mobile terminal, and the antenna is mainly used for data transmission. Different communication requirements have different requirements on the data transmission rate of the antenna, generally speaking, the requirements on the data transmission rate of conversation, web browsing and the like are low, and the requirements on the data transmission rate of certain games, video and the like are high.
The data transmission rate of the overlapping screen terminal with a single antenna radiation branch is low, in order to improve the antenna performance of the overlapping screen mobile terminal, the existing overlapping screen mobile terminal is generally provided with one antenna radiation branch on each of two modules of the overlapping screen terminal, and although the overlapping screen mobile terminal can improve the data transmission rate when being unfolded, the two antenna radiation branches can interfere with each other when being overlapped, so that the two antenna radiation branches can not work normally, and the communication quality is seriously influenced.
In summary, the existing overlapping screen mobile terminal cannot give consideration to the improvement of the antenna working performance during the unfolding, and avoids the mutual interference between the two antenna radiation branches during the overlapping.

As shown in fig. 1, an embodiment of the present invention provides a mobile terminal, including a first module 1 and a second module 2, where the first module 1 and the second module 2 can move relatively to an overlapped state or an unfolded state;
the first module 1 is provided with a first antenna radiation branch 3, the first antenna radiation branch 3 is provided with a first feeding point 31 and a first grounding point 32, the first feeding point 31 is electrically connected with the feed source on-off circuit 4, and the first grounding point 32 is electrically connected with the grounding on-off circuit 5; a second antenna radiation branch 6 is arranged on the second module 2, and a second feeding point 61 and a second grounding point 62 are arranged on the second antenna radiation branch 6;
when the first module 1 and the second module 2 are in an overlapped state, the feed source on-off circuit 4 and the grounding on-off circuit 5 are both in an off state; when the first module 1 and the second module 2 are in the unfolded state, the feed source on-off circuit 4 and the grounding on-off circuit 5 are both in the conduction state.
The Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The first module 1 can be a middle frame, a shell, a display module or the combination of the middle frame, the shell and the display module; the second module 2 can be a middle frame, a shell, a display module or a combination of the middle frame, the shell and the display module; the embodiments of the present invention are not limited to these examples.
The first module 1 and the second module 2 may be connected through a rotating shaft or a sliding rail. When the first module 1 and the second module 2 are connected through the rotating shaft, the first module 1 and the second module 2 can be in an overlapped state or an unfolded state in a manner of rotating around the rotating shaft; when the first module 1 and the second module 2 are connected by a slide rail, the first module 1 and the second module 2 may be in an overlapped state or an unfolded state by sliding along the slide rail (e.g., sliding left and right or up and down). The first module 1 and the second module 2 may also be overlapped and unfolded through other connection methods, which is not limited in the embodiment of the present invention.
The first antenna radiation branch 3 may be an antenna radiation branch in the form of a Flexible Printed Circuit (FPC), a laser direct structuring (LASER DIRECT scribing, LDS), a break-point middle frame, or the like; the second antenna radiation branch 6 may be an antenna radiation branch in the form of an FPC, an LDS, a break-point middle frame, or the like.
The first antenna radiation branch 3 may be electrically connected to a grounded first feed 41, where the first feed 41 may be a radio frequency module requiring multiple antennas, such as a third Generation mobile communication technology (3rd-Generation, 3G), a fourth Generation mobile communication technology (4G), a fifth Generation mobile communication technology (5th-Generation, 5G), WIreless Fidelity (WIFI), or Global Positioning System (GPS). The second antenna radiation branch 6 may be electrically connected to a grounded second feed 7, where the second feed 7 may be a radio frequency module requiring multiple antennas, such as 3G, 4G, 5G, WIFI or GPS; it should be noted that the second feeding point may be electrically connected to the second feeding source through a normally closed switch.
The feed switching circuit 4 may be used to switch on or off the electrical connection between the first feeding point 31 and the transceiver system 8, so as to put the first antenna radiation branch 3 in a feeding state or an isolated feeding state. The ground on/off circuit 5 can be used to connect or disconnect the first ground point 32 to the ground reference, so that the first antenna radiation branch 3 is in a grounded or ungrounded state.
In the embodiment of the invention, when the first module and the second module are in the unfolding state, the feed source on-off circuit and the grounding on-off circuit are both in the conduction state, so that the two antenna radiation branches can normally work; when the first module and the second module are overlapped, the feed source on-off circuit and the grounding on-off circuit are both in an off state, so that the first antenna radiation branch cannot work due to the fact that the first antenna radiation branch is in a state of isolating feed and isolating reference ground, namely, only the second antenna radiation branch can work normally at the moment, and mutual interference between the two antenna radiation branches in the overlapped state is avoided. Therefore, the overlapping screen mobile terminal can not only increase the antenna performance when being unfolded, but also avoid the mutual interference between the two antenna radiation branches when being overlapped.
In addition, in the embodiment of the present invention, when the two modules are overlapped, since the feed source on-off circuit is in the off state, that is, the first antenna radiation branch is isolated from the reference ground, when the two modules are overlapped, the first antenna radiation branch is prevented from interfering with the operation of the second antenna radiation branch due to being a parasitic antenna, and thus the normal operation of the second antenna radiation branch when the two modules are overlapped can be better ensured.
Optionally, the feed source on-off circuit 4 includes a first feed source 41 and a first switch 42 connected in series;
the first feed 41 is electrically connected to the first feeding point 31 and to the transceiver system 8 via the first switch 42; and/or the first feed 41 is electrically connected with the transceiver system 8 and is electrically connected with the first feeding point 31 through the first switch 42;
when the first module 1 and the second module 2 are in an overlapped state, the first switch 42 is in an off state; when the first module 1 and the second module 2 are in the unfolded state, the first switch 42 is in the conducting state.
Therefore, when the feed source on-off circuit comprises the first switch, the feed or isolation feed of the first antenna radiation branch can be realized only by controlling the on-off of the first switch, so that the structure is simpler, and the realization is easier.
Optionally, the ground on/off circuit 5 includes a second switch;
when the first module 1 and the second module 2 are in an overlapped state, the second switch is in an off state; when the first module 1 and the second module 2 are in the unfolded state, the second switch is in the conducting state.
When the ground connection/disconnection circuit 5 includes a second switch, the first antenna radiating branch 3 may be electrically connected to a reference ground through the second switch.
Therefore, when the grounding on-off circuit comprises the second switch, the first antenna radiating branch can be grounded or ungrounded only by controlling the on-off of the second switch, so that the structure is simpler and the realization is easier.
Optionally, the ground switching circuit 5 further comprises a first tuning circuit connected in series with the second switch.
The first tuning circuit may be configured to adjust a resonant frequency of the first antenna radiating branch. Specifically, the first tuning circuit may be a circuit formed by an inductor and/or a capacitor, or may be a switching circuit; when the first tuning circuit is a switch switching circuit, the switch switching circuit may be configured to be turned on when the resonant frequency is greater than a first preset threshold, and turned off when the resonant frequency is less than or equal to the first preset threshold, where the first preset threshold may be set according to specific requirements.
When the ground on/off circuit 5 further includes a first tuning circuit connected in series with the second switch, the first antenna radiating branch 3 may be connected to the reference ground through the first tuning circuit and the second switch, or may be connected to the reference ground through the second switch and the first tuning circuit.
Like this, because ground connection break-make circuit still includes first tuned circuit to make ground connection break-make circuit can possess simultaneously and tune and break-make reference ground two functions, like this, when first module and second module expand, can enough make first antenna radiation branch normal work, also can adjust first antenna radiation branch resonant frequency to the frequency channel that needs.
Optionally, the first tuning circuit comprises at least one first tuning branch.
The first tuning branch may be a switching branch, or may be a branch formed by an inductor and/or a capacitor, which is not limited in the embodiments of the present invention.
The first tuning circuit may include one, two, three or more first tuning branches. When the first tuning circuit comprises two or more first tuning branches, the tunable range of the resonance frequency of the first antenna radiating branch can be made larger.
Optionally, a tuning point 63 is disposed on the second antenna radiating branch 6, and the tuning point 63 is electrically connected to the second tuning circuit 9.
Wherein, the second tuning circuit 9 may be grounded; the second tuning circuit 9 described above may be used to adjust the resonance frequency of the second antenna radiating branch 6. The second tuning circuit 9 may be a circuit formed by an inductor and/or a capacitor, or may be a switching circuit; when the second tuning circuit 9 is a switching circuit, the switching circuit may be turned on when the resonant frequency is greater than a second preset threshold, and turned off when the resonant frequency is less than or equal to the second preset threshold, where the second preset threshold may be set according to specific requirements.
In this way, the second tuning circuit can adjust the resonant frequency of the radiating branch of the second antenna.
Optionally, the second tuning circuit 9 comprises at least one second tuning branch.
The second tuning branch may be a switching branch, or may be a branch formed by an inductor and/or a capacitor, which is not limited in the embodiments of the present invention.
The second tuning circuit 9 may include one, two, three or more second tuning branches. When the second tuning circuit comprises one or more than two second tuning branches, the adjustable range of the resonant frequency of the second antenna radiating branch can be made larger.
Optionally, the second grounding point 62 is located at an end of the second antenna radiating branch 6 close to the first antenna radiating branch 3.
The second grounding point 62 may be grounded through a grounding member (e.g., a spring or a probe).
Therefore, the second grounding point is positioned at one end of the second antenna radiation branch close to the first antenna radiation branch, so that when the first module and the second module are unfolded, the coupling transmission of the antenna energy between the two antenna radiation branches can be prevented, and the mutual interference between the two antenna radiation branches can be further reduced.
As shown in fig. 2, an embodiment of the present invention provides an antenna control method applied to a mobile terminal in the foregoing embodiment, including the following steps:
In the embodiment of the invention, when the first module and the second module are in the unfolding state, the feed source on-off circuit and the grounding on-off circuit are controlled to be in the conducting state, so that the two antenna radiation branches can work normally; when first module and second module overlap, control feed break-make circuit and ground connection break-make circuit all are in the off-state to make first antenna radiation branch unable work because of being in the state of keeping apart the feed and keeping apart the reference ground, only second antenna radiation branch can normally work this moment promptly, has avoided mutual interference between two antenna radiation branches under the overlapping condition. Therefore, the overlapping screen mobile terminal can not only increase the antenna performance when being unfolded, but also avoid the mutual interference between the two antenna radiation branches when being overlapped.
