In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of processing units means two or more processing units, and the like.
The following first explains some of the nouns or terms referred to in the claims and the specification of the present invention.
Folding screen type terminal equipment: refers to a terminal device having at least two screens, and at least two screens can be unfolded into one screen or folded into independent at least two screens. I.e. the screen of the terminal device may be in an unfolded state or in a folded state. The following description is schematically made taking an example in which the terminal device has two screens (e.g., a first screen and a second screen).
Fig. 1 (a) shows a schematic configuration diagram of the terminal device when the screen of the terminal device is in the unfolded state, in which the first screen and the second screen of the terminal device can be unfolded into one screen along the axis a 'B'. For convenience of description, a side of the terminal device where the first screen is located may be referred to as a first screen side, and a side of the terminal device where the second screen is located may be referred to as a second screen side.
The first screen can be a main screen, and the second screen can be an auxiliary screen. Alternatively, the first screen may be the sub-screen and the second screen may be the main screen. For example, the left side in fig. 1 (a) may be a main screen, and the right side may be a sub screen.
Fig. 1 (B) shows a schematic configuration diagram of the terminal device when the screens of the terminal device are in a folded state, in which the first screen and the first screen of the terminal device can be folded along the axis a 'B' into two separate screens.
In the prior art, the antenna unit of the terminal device is generally disposed on a single side, as shown in fig. 1 (a), the antenna unit 1 ' of the terminal device may be disposed on a first screen side of the terminal device, and the antenna unit 1 ' may include a first radiator 111 ' and a feed 112 ', and the first radiator 111 ' and the feed 112 ' may both be connected to a first ground patch 21 ' in the terminal device and located on the first screen side. Also, the secondary screen side of the terminal device may include a second ground tab 22'. For convenience of illustration and description, only the upper antenna unit of the terminal device is illustrated here, and the above antenna unit is schematically illustrated as an example.
Referring to fig. 1 (a), when the screen of the terminal device is in the unfolded state, the electromagnetic coupling between the second ground patch 22 'in the terminal device and located on the secondary screen side and the antenna unit 1' in the terminal device and located on the first screen side is very weak and can be ignored. However, referring to (b) of fig. 1, when the screen of the terminal device is in the folded state, since the second ground strip 22 'is closer to the antenna unit 1', a strong electromagnetic coupling phenomenon may be formed between the second ground strip 22 'and the antenna unit 1'. Since such an electromagnetic coupling phenomenon may cause a decrease in radiation efficiency of the antenna unit 1 ', it may cause a decrease in the overall performance of the antenna unit 1'.

On one hand, the area of the radiator of the antenna unit can be increased by adding the second radiator, so that the performance of the antenna unit can be improved. On the other hand, when the terminal device is in the folded state, after the second radiator is added, a certain distance exists between the ground strip located on one side of the second radiator in the terminal device and the second radiator in position, so that the influence of the ground strip on the second radiator can be reduced, that is, the electromagnetic coupling of the ground strip on the antenna unit is reduced, and the performance of the antenna unit can be improved.

Optionally, in the embodiment of the present invention, as shown in fig. 2, the terminal device provided in the embodiment of the present invention may further include a first ground strip 21 disposed in the first housing, and a second ground strip 22 disposed in the second housing.
It should be noted that, in the embodiment of the present invention, the first antenna module and the first ground strip are both disposed in the first housing and located in different areas of the first accommodating space formed between the first screen and the first housing. The second antenna module and the second grounding piece are arranged in the second shell and are located in different areas of a second accommodating space formed between the second screen and the second shell.

Optionally, in this embodiment of the present invention, the second radiator may be electrically connected to the first radiator in a direct contact manner, or the second radiator may be electrically connected to the first radiator in a coupling manner, or the second radiator may be electrically connected to the first radiator by a connection element, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited thereto.
Optionally, in the embodiment of the present invention, the connecting element may be a flexible metal connecting element, a switching element, an inductance element, or a capacitance element, or any other possible connecting element, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
For example, taking the connection element as the switch element, the terminal device may control the switch element to be turned on or off according to the actual usage situation, so as to control the connection or disconnection between the first radiator and the second radiator.
Optionally, in this embodiment of the present invention, a size of the first radiator in the first direction may be greater than or equal to a size of the second radiator in the second direction. The first direction may be a direction corresponding to a maximum size of the first radiator, and the second direction may be a direction corresponding to a maximum size of the second radiator. For example, the length of the first radiator may be greater than or equal to the length of the second radiator.
For example, as shown in fig. 3, assuming that the first direction and the second direction are the same and are directions shown as X in fig. 3, and a dimension of the first radiator 111 in the first direction X (i.e., a length of the first radiator 111) is L1, and a dimension of the second radiator 121 in the second direction X (i.e., a length of the second radiator 121) is L2, in this embodiment of the present invention, L1 may be equal to L2, or L1 may be greater than L2, which may be determined according to practical use requirements, and the embodiment of the present invention is not limited thereto.
In the embodiment of the present invention, the feed source may be connected to a radio frequency front end module in the terminal device, and the radio frequency front end module may be configured to transmit a current (e.g., an alternating current) to the feed source or receive a current from the feed source.
Optionally, in this embodiment of the present invention, with reference to fig. 2, as in the terminal device 2 shown in fig. 4, the first antenna module 11 may further include a first tuning element 113 connected to the first radiator 111. The first tuning element 113 may be used for tuning the resonance length of the antenna unit of the terminal device 2. Wherein the resonance length may be represented by a distance that a current flows in a radiator of the antenna element.
As is known from the basic operating principle of an antenna, the resonant length of an antenna element is inversely proportional to the resonant frequency of the antenna. Specifically, the longer the resonant length of the antenna unit is, the smaller the resonant frequency of the antenna is; the shorter the resonant length, the greater the resonant frequency of the antenna. Thus, by tuning the resonant length of the antenna element, the antenna can be made to produce different resonant frequencies.
Optionally, in this embodiment of the present invention, the first tuning element may be configured to increase a resonant length of the antenna unit, so as to reduce a resonant frequency of the antenna unit. The first tuning element may also be configured to reduce the resonant length of the antenna element and increase the resonant frequency of the antenna element.
Optionally, in this embodiment of the present invention, the first tuning element may be a capacitance element with a variable capacitance value, may also be a tuning switch, and may also be a tuning element in any other possible form for tuning a resonant length of the antenna unit, which may be determined specifically according to actual usage requirements, and this embodiment of the present invention is not limited. Taking the first tuning element as an example of the tuning switch, the tuning switch may include a switch (e.g., a single-pole multi-throw switch) and a plurality of capacitive elements, and the switch may be connected to at least one of the plurality of capacitive elements according to actual usage requirements to tune a resonant length of the antenna unit.
Optionally, in this embodiment of the present invention, with reference to fig. 4, as in the terminal device 2 shown in fig. 5, the second antenna module 12 may further include a second tuning element 122 connected to the second radiator 121. The second tuning element 122 may be used to tune the resonance length of the antenna element.
Optionally, the second tuning element may be configured to increase a resonant length of the antenna unit, so that a resonant frequency of the antenna unit is decreased. The second tuning element may also be used to reduce the resonant length of the antenna element and increase the resonant frequency of the antenna element.
Optionally, the second tuning element may be a capacitance element with a variable capacitance value, may also be a tuning switch, and may also be any other possible form of tuning element for tuning a resonance length of the antenna unit, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
In the embodiment of the present invention, the first tuning element and the second tuning element may be the same type of tuning element, or may be different types of tuning elements. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In the embodiment of the present invention, the first tuning element in the first antenna module and the second tuning element in the second antenna module are both grounded. For example, in the embodiment of the present invention, the first tuning element in the first antenna module is connected to the first ground pad, and the second tuning element in the second antenna module is connected to the second ground pad, which is an exemplary illustration.
Illustratively, in the terminal device 2 shown in fig. 5, the first radiator 111 and the first tuning element 113 in the first antenna module 11 are both connected to the first ground pad 21, and the second radiator 121 and the second tuning element 122 in the second antenna module 12 are both connected to the second ground pad 22.
For example, as shown in fig. 5, the first radiator 111 in the first antenna module 11 may be connected to the first ground pad 21 through a metal body at one end of the first radiator 111, and the second radiator 121 in the second antenna module 12 may be connected to the second ground pad 22 through a metal body at one end of the second radiator 121. Of course, the connection mode between the first radiator 111 and the first ground strip 21 and the connection mode between the second radiator 121 and the second ground strip 22 may also be any other possible connection modes, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
Optionally, in this embodiment of the present invention, the feed may be connected to a first target location on the first radiator, the first tuning element may be connected to a second target location on the first radiator, and the second tuning element may be connected to a third target location on the second radiator. Wherein the first target position is located between the second target position and the third target position.
For example, as shown in fig. 5, the feed 112 may be disposed on a side of the first radiator 111 close to the second radiator 121 and connected to the first radiator 111. The first tuning element 113 may be arranged in connection with the first radiator 111 at a side of the first radiator 111 remote from the second radiator 121. A second tuning element 122 may be arranged in connection with the second radiator 121 on a side of the second radiator 121 close to the first radiator 111. The specific setting positions of the feed source and the first tuning element in the first antenna module and the second tuning element in the second antenna module may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
With reference to fig. 6, fig. 7, and fig. 8, a flow path of a current of the antenna unit in the terminal device provided in the embodiment of the present invention during a process of radiating a signal is exemplarily described below.
For convenience of description, the following describes an exemplary current flow path of the antenna unit during signal radiation by marking different positions on the first radiator and the second radiator in the antenna unit.
Optionally, in the embodiment of the present invention, because the first radiator is connected to the feed source, the first tuning element, the first ground strip, and the second radiator at different positions, that is, a first position, a second position, a third position, and a fourth position, may be marked on the first radiator according to the connection relationship, where the first position, the second position, the third position, and the fourth position are different.
As shown in fig. 6, a position P1 on the first radiator 111 connected to the feed 112 may be marked as a first position, a position P2 on the first radiator 111 connected to the first tuning element 113 may be marked as a second position, a position P3 on the first radiator 111 connected to the first ground pad 21 may be marked as a third position, and a position P4 on the first radiator 111 coupled to the second radiator 121 may be marked as a fourth position.
It should be noted that, in the embodiments of the present invention, each of the above embodiments is exemplified by taking one feed source and one first tuning element as an example, and in actual implementation, the number of the feed sources and the first tuning elements may also be multiple. It will be appreciated that when the number of feeds and first tuning elements is plural, the first and second locations may also be plural, i.e. one first location for each feed and one second location for each first tuning element.
Optionally, in this embodiment of the present invention, since the second radiator is connected to the first radiator, the second tuning element, and the first ground pad at different positions, that is, a fifth position, a sixth position, and a seventh position, may be marked on the second radiator according to the connection relationship, where the fifth position, the sixth position, and the seventh position are different.
As shown in fig. 6, a position P5 on the second radiator 121 coupled to the first radiator 111 may be marked as a fifth position, a position P6 on the second radiator 121 connected to the second tuning element 122 may be marked as a sixth position, and a position P7 on the second radiator 121 connected to the second ground pad 22 may be marked as a seventh position.
In the embodiments of the present invention, each of the above embodiments is exemplified by taking one second tuning element as an example, and in actual implementation, the number of the second tuning elements may be multiple. It is to be understood that when the number of the second tuning elements is plural, the sixth position may also be plural, that is, one sixth position corresponds to each second tuning element.
In the embodiment of the present invention, the radiation frequency (also referred to as a resonant frequency) of the antenna unit may be in the first frequency band, or may be in the second frequency band. The maximum value of the first frequency band may be smaller than or equal to the minimum value of the second frequency band. For ease of illustration and understanding, the first frequency band may be referred to hereinafter as the low frequency range and the second frequency band as the high frequency range.
Optionally, in an embodiment of the present invention, the first frequency band may be [700 megahertz (MHz), 960MHz ]. The second frequency band may be [1710MHz, 2690MHz ].
It should be understood that the first frequency band and the second frequency band are only exemplary lists, and may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
Next, referring to fig. 7, the flow path of the current of the antenna unit in the case where the radiation frequency of the antenna unit is in the low frequency range is exemplarily described using the respective positions marked on the first radiator 111 and the respective positions marked on the second radiator 121 as shown in fig. 6.
Alternatively, in the embodiment of the present invention, in the case that the radiation frequency of the antenna unit is in the first frequency band (i.e., the low frequency range), in the process of radiating a signal by the antenna unit, as shown in fig. 7, the current of the antenna unit may flow along the dotted line in fig. 7 toward the direction indicated by the arrow, that is, from the feed 112, first flow to the first radiator 111, and sequentially flow to the second radiator 121 through the first position P1 and the fourth position P4 of the first radiator 111, and sequentially flow to the second ground patch 22 through the fifth position P5 and the seventh position P7 of the second radiator 121.
In the above-described flow path of the current of the antenna element, the resonance length of the antenna element may be represented by L3+ L4. Where L3 is a distance from the first position P1 to the fourth position P4 of the first radiator 111, and L4 is a distance from the fifth position P5 to the seventh position P7 of the second radiator 121. In the embodiment of the invention, under the condition of low-frequency resonance, the resonance length of the antenna unit is increased, so that the low-frequency resonance frequency generated by the antenna unit can be expanded to a lower frequency value compared with the prior art.
Next, referring to fig. 8, the flow path of the current of the antenna unit in the case where the radiation frequency of the antenna unit is in the high frequency range is exemplarily described using the respective positions marked on the first radiator 111 and the respective positions marked on the second radiator 121 as shown in fig. 6.
Alternatively, in the embodiment of the present invention, in the case that the radiation frequency of the antenna unit is in the second frequency band (i.e., the high frequency range), in the process of radiating a signal by the antenna unit, as shown in fig. 8, the current of the antenna unit may flow along the dotted line in fig. 8 toward the direction indicated by the arrow, that is, from the feed 112, first flow to the first radiator 111, and then flow to the first tuning element 113 through the first position P1 and the second position P2 of the first radiator 111, and then flow to the first ground patch 21 through the first tuning element 113. Also, the current of the antenna unit may flow from the feed 112 to the first radiator 111, and then flow to the second tuning element 122 through the first position P1, the fourth position P4, the fifth position P5 and the sixth position P6 of the first radiator 111, and then flow to the second ground patch 22 through the second tuning element 122.
In the above-described flow path of the current of the antenna element, the resonance length of the antenna element may be represented by L5 and (L3+ L6). Where L5 is a distance from the first position P1 of the first radiator 111 to the second position P2, L3 is a distance from the first position P1 of the first radiator 111 to the fourth position P4, and L6 is a distance from the fifth position P5 of the second radiator 121 to the sixth position P6. It should be noted that when L5 is equal to or approximately equal to (L3+ L6), the antenna unit can generate a high-frequency resonant frequency; when the difference between L5 and (L3+ L6) exceeds a threshold, the antenna element may generate two different high-frequency resonant frequencies.
The first tuning element and the second tuning element may be used to tune a resonant length of the antenna unit. Assuming that the first tuning element can generate a resonance length of ±. Δ 1 and the second tuning element can generate a resonance length of ±. Δ 2, the resonance lengths of the antenna elements can be tuned in the ranges of [ L5- Δ 1, L5 +. Δ 1] and [ (L3+ L6) -. Δ 2, (L3+ L6) +. Δ 2] (corresponding to the above-mentioned high-frequency range), so that the high-frequency resonance range of the antenna element can be expanded.
In the embodiments of the present invention, the length of the second radiator is equal to the length of the first radiator (i.e., the second radiator and the first radiator are arranged in a mirror image manner). It is understood that the second radiator may be arranged in other possible manners according to actual use requirements.
For example, as shown in fig. 9, when the length L2 of the second radiator 121 is less than the length L1 of the first radiator 111, in the case where the radiation frequency of the antenna unit is in the second frequency band (i.e., the high frequency range), the terminal device may control the current of the antenna unit to flow to the second radiator 121 to generate high frequency resonance. Also, in the case where the radiation frequency of the antenna unit is in the first frequency band (i.e., the low frequency range), the terminal device may control the current of the antenna unit to flow in the first radiator 111 but not to flow to the second radiator 121 to generate low frequency resonance. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In the embodiment of the present invention, fig. 7 and fig. 8 are both illustrated by taking the flow path of the current of the antenna unit when the terminal device is in the unfolded state as an example, and in the practical application process, the flow path of the current of the antenna unit when the terminal device is in the folded state is similar to the flow path of the current of the antenna unit when the terminal device is in the unfolded state. Therefore, for the description of the flowing path of the current of the antenna unit when the terminal device is in the folded state, reference may be specifically made to the description related to the embodiment shown in fig. 7 and fig. 8, and the description is not repeated here.
Fig. 10 shows a schematic configuration diagram of the terminal device in a folded state. As shown in fig. 10, the first radiator 111 and the second radiator 121 are coupled to each other, and the current in the first radiator 111 and the current in the second radiator 121 may be the same or substantially the same (for example, the difference between the two currents is within a preset range), so that the first radiator 111 and the second radiator 121 do not interfere with each other and generate noise, and the addition of the second radiator may increase the area of the radiator of the antenna unit, thereby increasing the radiation efficiency of the antenna unit. In addition, since the second radiator 121 and the second ground strip 22 have a certain distance H therebetween, the electromagnetic coupling between the second ground strip 22 and the first radiator 111 and the second radiator 121 may be weakened to some extent, so that the radiation efficiency of the antenna unit may be further improved.
Optionally, in this embodiment of the present invention, the terminal device may sense whether the screen of the terminal device is in the unfolded state or in the folded state through a sensor (e.g., a magnetic sensor) in the terminal device. Then, the terminal device may control connection or disconnection between the first radiator and the second radiator according to the state of the screen.
For example, in an embodiment of the present invention, in the case that the first radiator and the second radiator are connected through the connection element, the terminal device may control the connection element to be turned on or off according to different states of a screen of the terminal device, so as to control connection or disconnection between the first radiator and the second radiator. Thereby, the antenna unit can have different performances when the screen of the terminal device is in different states. So that the antenna unit can have better performance under different conditions.
The embodiment of the invention provides terminal equipment, which comprises a first shell, a second shell, a first antenna module and a second antenna module, wherein the first antenna module is arranged in the first shell; the first antenna module comprises a first radiator and a feed source connected with the first radiator, and the second antenna module comprises a second radiator; the second radiator is electrically connected with the first radiator. Through the scheme, the first shell and the second shell of the terminal device are movably connected, so that the terminal device can be folded or unfolded; compared with the antenna unit applied to the terminal device in the prior art, the terminal device provided by the embodiment of the invention is additionally provided with the second radiator on the basis of the first radiator, and the second radiator is electrically connected with the first radiator. On one hand, the area of the radiator of the antenna unit can be increased by adding the second radiator, so that the performance of the antenna unit can be improved. On the other hand, when the terminal device is in the folded state, after the second radiator is added, a certain distance exists between the ground strip located on one side of the second radiator in the terminal device and the second radiator in position, so that the influence of the ground strip on the second radiator can be reduced, that is, the electromagnetic coupling of the ground strip on the antenna unit is reduced, and the performance of the antenna unit can be improved.
