Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The scheme provided by the application can be used in a terminal used in daily life, and in a real scene of multi-band application when an antenna in the terminal is designed, for convenience of understanding, some terms and application scenes related to the embodiment of the application are first briefly introduced below.
MIMO (Multiple-Input Multiple-Output) technology: the method is a technology for performing space diversity by using a plurality of transmitting antennas and receiving antennas at a transmitting end and a receiving end respectively, adopts a discrete multi-antenna, and can decompose a communication link into a plurality of parallel sub-channels, thereby improving the capacity of transmitting or receiving signals.
Injection molding: it is a method for producing and shaping industrial products. Rubber injection molding and plastic injection molding are commonly used. The injection molding can be classified into injection molding and die casting.
In daily life, people can use the terminal to work, study, entertain and the like. The user may transmit various data through an antenna in the terminal, for example, the user may send information such as a picture and a video taken by the user to another terminal, or the user may perform a voice call, a video call, and the like with another user through the terminal to transmit voice data or video data.
Please refer to fig. 1, which shows a schematic view of an application scenario of a terminal transmitting data according to an exemplary embodiment of the present application. As shown in fig. 1, a number of terminals 110 are included.
Alternatively, the terminal 110 is a terminal to which an antenna designed to transmit signals can be installed. For example, the terminal may be a mobile phone, a tablet computer, an e-book reader, smart glasses, a smart watch, an MP3 player (Moving picture Experts Group Audio Layer III, motion picture Experts Group Audio Layer IV, motion picture Experts Group Audio Layer 4), an MP4 player, a notebook computer, a laptop computer, a desktop computer, and the like.
In the environment shown in fig. 1, the terminal needs to operate in various data transmission scenarios, and in order to adapt to data transmission in various frequency bands, the antenna designed in the terminal may change its own operating state accordingly, so as to operate in the corresponding frequency band. For example, the terminal may use its own metal frame as an antenna, and set up a gap on the metal frame, so as to form a plurality of antennas, and transmit data using the plurality of antennas (may also be regarded as a MIMO antenna). Optionally, in order to widen the supported operating frequency band of a single antenna, the single antenna may operate at multiple frequencies, and a circuit switch may be further added between the ground plate and the feeding end or the branch of the antenna in the terminal to change a circuit path of the antenna, thereby achieving a multi-frequency coverage effect of the antenna. Because extra circuits need to be designed for the antenna, more circuit lines need to be arranged, the antenna circuit lines are complex, and the short circuit phenomenon easily occurs, so that the conversion of the antenna is influenced.
In order to avoid complicated circuit wiring in the terminal and reduce the complexity of the antenna circuit, the application provides a solution, which can realize the effect of changing the antenna used for transmitting signals in the terminal and covering multiple frequencies under the condition of not setting redundant switch circuits. Please refer to fig. 2, which illustrates a schematic structural diagram of an antenna module according to an exemplary embodiment of the present application. The antenna module provided by the embodiment of the present application can be applied to the terminal in the application scenario shown in fig. 1. As shown in fig. 2, the antenna module includes: a phase change device 201 and a first antenna group 202;
wherein, the first antenna group 202 includes a first antenna portion 203 and a second antenna portion 204; the first antenna portion 203 further comprises a first port 203a of the first antenna portion and the second antenna portion 204 further comprises a second port 204a of the second antenna portion.
The first port 203a of the first antenna portion and the second port 204a of the second antenna portion are connected through the phase change device 201.
Optionally, the phase change device 201 may be disposed between the first port 203a of the first antenna portion and the second port 204a of the second antenna portion by means of a middle frame injection molding.

That is, the phase change device 201 may realize the conduction of the circuit between the first port 203a of the first antenna portion and the second port 204a of the second antenna portion in the crystalline state, and the phase change device 201 may realize the disconnection of the circuit between the first port 203a of the first antenna portion and the second port 204a of the second antenna portion in the amorphous state.
When the phase change device 201 is changed from the amorphous state to the crystalline state, the first antenna portion 203 and the second antenna portion 204 are combined into all or part of the same antenna. Optionally, all of the same antenna means that the first antenna portion 203 and the second antenna portion 204 are a complete antenna after being combined, and the terminal may use the antenna formed by combining the first antenna portion 203 and the second antenna portion 204 to transmit signals.
Optionally, the portion of the same antenna means that the first antenna portion 203 and the second antenna portion 204 are a part of a complete antenna after being combined. Please refer to fig. 3, which shows a schematic structural diagram of a first antenna portion and a second antenna portion according to an exemplary embodiment of the present application. As shown in fig. 3, the antenna comprises a first antenna portion 301, a second antenna portion 302, a third antenna portion 303, a first phase change device 304, a second phase change device 305, a first antenna 306, and a fourth antenna portion 307. When the first phase change device 304 and the second phase change device 305 are both changed from the amorphous state to the crystalline state, the first antenna portion 301 and the second antenna portion 302 are combined to form a fourth antenna portion 307, and the fourth antenna portion 307 is a part of an antenna 306 formed by combining the first antenna portion 301, the second antenna portion 302 and the third antenna portion 303.
When the phase change device 201 changes from the crystalline state to the amorphous state, the first antenna portion 203 and the second antenna portion 204 do not belong to the same antenna. Alternatively, when the phase change device 201 is amorphous, the first antenna portion 203 may be a separate antenna, and the second antenna portion 204 may be another separate antenna.
Alternatively, when the phase change device 201 is amorphous, the first antenna portion 203 may be a portion of a separate antenna, and the second antenna portion 204 may be a portion of another separate antenna. For example, when the phase change device 201 is amorphous, the first antenna portion 203 may be a segment of an antenna radiating arm of a certain antenna, and the second antenna portion 204 may be a segment of an antenna radiating arm of another antenna. This is not limited by the examples of the present application.
In summary, the antenna module provided by the present application includes a phase change device and a first antenna group; the first antenna group comprises a first antenna part and a second antenna part; the first port of the first antenna part is connected with the second port of the second antenna part through a phase change device; the phase change device comprises a crystalline state and an amorphous state, the phase change device has a conductive function in the crystalline state, and the phase change device has an insulating function in the amorphous state; when the phase change device is changed from an amorphous state to a crystalline state, the first antenna part and the second antenna part are combined into all or part of the same antenna; when the phase change device is changed from the crystalline state to the amorphous state, the first antenna part and the second antenna do not belong to the same antenna. The first antenna part and the second antenna part are combined or separated through the conversion of the phase change device between the crystalline state and the amorphous state, so that the form of the antenna is changed, the antenna is supported to work in different modes and the resonant frequency is changed, other external circuits are prevented from being designed for the antenna, and the complexity of the antenna circuit is reduced.
In a possible implementation manner, the phase change device comprises a connector and a plating part, wherein the connector is used for connecting the first antenna part and the second antenna part, the plating part is also connected with the first antenna part and the second antenna part, and the plating part is used for realizing the conversion between the crystalline state and the amorphous state of the phase change device. The embodiment shown in FIG. 2 will be described below by taking as an example a case where the plated portion is a plated layer formed by plating a film on the interconnect.
Please refer to fig. 4, which illustrates a schematic structural diagram of an antenna module according to an exemplary embodiment of the present application. The antenna module provided by the embodiment of the present application can be applied to the terminal in the application scenario shown in fig. 1. As shown in fig. 4, the antenna module includes: a phase change device 401 and a first antenna group 402.
The first antenna group 402 includes a first antenna portion 403 and a second antenna portion 404; the first antenna portion 403 also includes a first port 403a of the first antenna portion and the second antenna portion 404 also includes a second port 404a of the second antenna portion.
The first port 403a of the first antenna portion and the second port 404a of the second antenna portion are connected through the phase change device 401.
The phase change device 401 includes a connector 405 and a plated portion 406, wherein the connector 405 is used for connecting the first antenna portion 403 and the second antenna portion 404; the plated part 406 is plated on the surface of the connector 405 and connected to the first port 403a of the first antenna part and the second port 404a of the second antenna part; plated portion 406 is a phase change material that includes crystalline and amorphous states.
Optionally, the connecting body 405 may be disposed between the first port 403a of the first antenna portion and the second port 404a of the second antenna portion by a middle frame injection molding method, and the phase change material is plated on the surface of the connecting body 405 by a plating process and connected to the first port 403a of the first antenna portion and the second port 404a of the second antenna portion. The phase change material has a crystalline state and an amorphous state, and when the phase change material is in the crystalline state, the phase change material has a conductive function, and when the phase change material is in the amorphous state, the phase change material has an insulating function, so that the phase change device 401 indirectly exhibits the crystalline state and the amorphous state.
In one possible implementation, to achieve the above-described function of phase change device 401 having crystalline and amorphous states, connector 405 may be an insulating material, such that the state of phase change device 401 follows the state change of plated portion 406. For example, the connecting body 405 is made of plastic, and is disposed between the first port 403a of the first antenna portion and the second port 404a of the second antenna portion by means of a middle frame injection molding, and then the phase change material is plated on the surface of the connecting body 405 by a plating process and is connected with the first port 403a of the first antenna portion and the second port 404a of the second antenna portion. Therefore, when the phase change material is in the crystalline state, the phase change material has a conductive function, that is, the plating layer part 406 has a conductive function, and the phase change device 401 realizes the conductive function through the plating layer part 406 thereof, which is equivalent to being in the corresponding crystalline state. When the phase change material is in an amorphous state, the phase change material has an insulating function, that is, the plating layer portion 406 has an insulating function, and the phase change device 401 does not have a conductive function as a whole, which is equivalent to being in a corresponding amorphous state.
Alternatively, the connecting body 405 may also be a phase change material. In this case, the phase change device is made of phase change material as a whole. That is, the phase change material may be disposed between the first port 403a of the first antenna portion and the second port 404a of the second antenna portion by means of the middle frame injection molding, and the phase change device realizes the transformation between the crystalline state and the amorphous state due to the property of the phase change material itself.
Optionally, the phase change material may be germanium antimony tellurium gst (gesbte) material or germanium tellurium gt (gete) material. Please refer to table 1, which shows an electrical parameter table of a phase change material according to an exemplary embodiment of the present application.
TABLE 1
Wherein x, y, z may be (1, 1, 2), (1, 2, 4), (2, 2, 5). Alternatively, if the results of combining other GST materials, the relative dielectric constant and conductivity (Siemens/m)-1) Within the scope shown above, the embodiments of the present application are also applicable, and are not described herein again.
As shown in Table 1, two phase change materials related to the embodiments of the present application, and their corresponding relative dielectric constants and conductivities (Siemens/m)-1). The phase change material may be any of a GST material or a GT material. Optionally, the phase change material may also be graphene, liquid crystal, vanadium oxide (e.g., vanadium dioxide), or other materials.
In one possible implementation, there is a first gap between the first port 403a of the first antenna portion and the second port 404a of the second antenna portion; phase change device 401 is disposed within the first gap. Please refer to fig. 5, which illustrates a schematic structural diagram of an antenna module related to fig. 4 according to an exemplary embodiment of the present application. As shown in fig. 5, the antenna module includes: a phase change device 501 and a first antenna group 502. The first antenna group 502 includes a first antenna portion 503 and a second antenna portion 504; the first antenna portion 503 further includes a first port 503a of the first antenna portion and the second antenna portion 504 further includes a second port 504a of the second antenna portion. A first gap 505 exists between the first port 503a of the first antenna portion and the second port 504a of the second antenna portion. The phase change device 501 may be designed within the first gap 505, i.e., the size of the phase change device 501 is smaller than the size of the first gap 505.
Optionally, in fig. 5, a size of the phase change device may also be larger than a size of the first gap, and the phase change device may also implement the conversion between the crystalline state and the amorphous state, which is not described herein again.
Optionally, the antenna module shown in fig. 4 further includes a trigger device 407, and the phase change devices may be induced by the trigger device 407. That is, trigger device 407 is used to induce phase change device 401 to change phase change device 401 from the amorphous state to the crystalline state. Alternatively, trigger device 407 is used to induce phase change device 401 to change phase change device 401 from the crystalline state to the amorphous state. That is, trigger device 407 may perform the functions of changing phase change device 401 from the crystalline state to the amorphous state, and changing phase change device 401 from the amorphous state to the crystalline state.
Optionally, the triggering device is any one of a laser excitation device, a temperature control device and a power-on device.
In one possible implementation, the triggering device is a laser excitation device for lasing the phase change device to induce the phase change device. For example, in fig. 4 described above, when the phase change device is in the crystalline state, the laser excitation device (trigger device 407) may emit laser light to the phase change device 401, and the phase change material in the phase change device is excited by the laser light, so that the phase change material may change from the crystalline state to the amorphous state. Correspondingly, the laser excitation device may also continue to emit laser to the phase change device 401, so that the phase change material in the phase change device may be restored from the amorphous state to the crystalline state, that is, the laser excitation device may change an energy parameter of the emitted laser, and emit laser that the phase change material in the phase change device needs to be changed into the crystalline state or the amorphous state, so as to induce the phase change material to change from the amorphous state to the crystalline state, or from the crystalline state to the amorphous state. For example, the phase change material may be in a crystalline state under the laser with the first energy, the phase change material may be in an amorphous state under the laser with the second energy, and if the phase change material needs to be changed from the crystalline state to the amorphous state, the laser excitation device may emit the laser with the second energy to the phase change device, so as to induce the phase change material to be changed from the crystalline state to the amorphous state; if the phase change material needs to be changed from the amorphous state to the crystalline state, the laser excitation device may emit laser light of energy one to the phase change device, thereby inducing the phase change material to change from the amorphous state to the crystalline state.
In one possible implementation, the trigger device is a temperature control device for changing the temperature of the phase change device to induce the phase change device. For example, in FIG. 4 above, when the phase change device is in the crystalline state, a temperature control device (trigger device 407) may change the temperature of phase change device 401, and the phase change material in the phase change device is activated by the change in temperature, such that the phase change material may change from the crystalline state to the amorphous state. Accordingly, the temperature control device may also continue to change the temperature of phase change device 401 such that the phase change material in the phase change device may be restored from the amorphous state to the crystalline state, i.e., the temperature control device may give the phase change material in the phase change device a temperature at which it needs to change to the crystalline state or the amorphous state, induce the phase change material to change from the amorphous state to the crystalline state, or change from the crystalline state to the amorphous state. For example, the phase change material may be in a crystalline state at a first temperature, the phase change material may be in an amorphous state at a second temperature, and if the phase change material needs to be changed from the crystalline state to the amorphous state, the temperature control device may change the temperature of the phase change device to the second temperature, thereby inducing the phase change material to be changed from the crystalline state to the amorphous state; if the phase change material needs to be changed from the amorphous state to the crystalline state, the temperature control device may change the temperature of the phase change device to temperature one, thereby inducing the phase change material to change from the crystalline state to the amorphous state.
In one possible implementation, the trigger device is an energizing device for energizing the phase change device to induce the phase change device. For example, in fig. 4, when the phase change device is in the crystalline state, the power-on device (trigger device 407) may apply a voltage to the phase change device through the power-on line to change the voltage of the phase change device 401, and the phase change material in the phase change device is activated by the voltage, so that the phase change material may be changed from the crystalline state to the amorphous state. Accordingly, the phase change material in the phase change device may be restored from the amorphous state to the crystalline state by applying a voltage to the phase change device, that is, the phase change material in the phase change device may be given a voltage required to change to the crystalline state or the amorphous state by the energization device, and the phase change material is induced to change from the amorphous state to the crystalline state or from the crystalline state to the amorphous state. For example, the phase change material may be in a crystalline state at a first voltage, the phase change material may be in an amorphous state at a second voltage, and if the phase change material needs to be changed from the crystalline state to the amorphous state, the voltage of the phase change device may be changed to the second voltage by the energization device, so as to induce the phase change material to be changed from the crystalline state to the amorphous state; if the phase change material needs to change from the amorphous state to the crystalline state, the application of a voltage to the phase change device may change the voltage of the phase change device to a voltage of one, thereby inducing the phase change material to change from the crystalline state to the amorphous state.
Please refer to fig. 6, which illustrates a schematic structural diagram of another antenna module related to fig. 4 according to an exemplary embodiment of the present application. As shown in fig. 6, a phase change device 601, a trigger device 602, a first probe point 603, and a second probe point 604 are included. The trigger device 602 may apply a voltage to the first probe point 603 and the second probe point 604 through a pass line, and when the voltage of the phase change material is changed into a first voltage, the phase change material in the phase change device 601 may be changed into a crystalline state, and when the trigger device 602 applies a voltage to the first probe point 603 and the second probe point 604 through a pass line, the voltage of the phase change material is changed into a second voltage, the phase change material in the phase change device 601 may be changed into a crystalline state again. Wherein the phase change material may be in a crystalline state at a first voltage and the phase change material may be in an amorphous state at a second voltage.
Optionally, the first antenna portion 403 shown in fig. 4 is a parasitic antenna, and the second antenna portion 404 is an inverted F antenna; when the first antenna portion 403 and the second antenna portion 404 are combined into all of the same antenna, the same antenna is a LOOP antenna (also referred to as a LOOP antenna). That is, when the phase-change device 401 is in the amorphous state, the second antenna portion is an independent inverted-F antenna, the first antenna portion is a parasitic antenna depending on the operation of the second antenna portion, and the second antenna portion may excite the first antenna portion to operate in a coupling manner when operating. When the phase change device 401 is in the crystalline state, the first antenna portion and the second antenna portion are combined into one LOOP antenna, and operation is performed through the LOOP antenna.
In a possible implementation manner, when the first antenna portion 403 and the second antenna portion 404 shown in fig. 4 are combined into all of the same antenna, the antenna feeding point of the same antenna is at the center of the radiation arm of the same antenna, and the phase change device is at one quarter of the radiation arm of the same antenna. Please refer to fig. 7, which illustrates a schematic structural diagram of an antenna according to an exemplary embodiment of the present application. As shown in fig. 7, the phase change device 701, the first antenna group 702, the antenna feeding point 703, the first antenna group 702 further includes a first antenna portion 704 and a second antenna portion 705. The antenna feed point 703 is located at the center of the antenna radiation arm, and the phase change device 701 is located at one quarter of the antenna radiation arm.
The first antenna portion 704 and the second antenna portion 705 may produce a quarter-wave resonant mode when the phase change device 701 is in the amorphous state, and the first antenna portion 704 and the second antenna portion 705 may constitute a LOOP antenna with an antenna feed point located at the center of the antenna radiating arm, which may produce a half-wave resonant mode, when the phase change device 701 is in the crystalline state. Alternatively, the position of the phase change device 701 may be designed according to actual requirements (for example, located at one eighth of the radiating arm of the antenna, or other positions, etc.), and this is not limited in this embodiment of the application.
It should be noted that, in the embodiment of the present application, both the first antenna portion and the second antenna portion may be inverted-F antennas or other types of antennas, and the operation principle thereof may also be similar to the description of the parasitic antenna and the inverted-F antenna, and details are not described here again.
Alternatively, the LOOP antenna described in the embodiments of the present application may be replaced with another type of antenna. For example, for a PIFA (Planar Inverted F-shaped Antenna), the phase change device may also be made into a Planar shape, which is not limited in the present application, and the PIFA Antenna changes into different Antenna portions or is recombined into itself according to the phase change device, which may also refer to the manner in the embodiments of the present application, and is not described herein again.
In summary, the antenna module provided by the present application includes a phase change device and a first antenna group; the first antenna group comprises a first antenna part and a second antenna part; the first port of the first antenna part is connected with the second port of the second antenna part through a phase change device; the phase change device comprises a crystalline state and an amorphous state, the phase change device has a conductive function in the crystalline state, and the phase change device has an insulating function in the amorphous state; when the phase change device is changed from an amorphous state to a crystalline state, the first antenna part and the second antenna part are combined into all or part of the same antenna; when the phase change device is changed from the crystalline state to the amorphous state, the first antenna part and the second antenna do not belong to the same antenna. The first antenna part and the second antenna part are combined or separated through the conversion of the phase change device between the crystalline state and the amorphous state, so that the form of the antenna is changed, the antenna is supported to work in different modes and the resonant frequency is changed, other external circuits are prevented from being designed for the antenna, and the complexity of the antenna circuit is reduced.
Please refer to fig. 8, which illustrates a schematic structural diagram of a terminal according to an exemplary embodiment of the present application. As shown in fig. 8, the terminal 800 includes a first antenna module 801, a second antenna module 802, a third antenna module 803, and a fourth antenna module 804, and a plurality of antenna modules may share a same ground plane 805. The first antenna module 801, the second antenna module 802, the third antenna module 803 and the fourth antenna module 804 can all adopt the antenna module provided in fig. 2 or fig. 3. Optionally, when the terminal uses one or two antenna modules to send data such as messages and videos, the terminal may determine whether to change the form of the antenna according to the frequency sent in the actual antenna module, and when the form of the antenna needs to be changed, the terminal may change from the amorphous state to the crystalline state by controlling the phase change device, or change from the crystalline state to the amorphous state by controlling the phase change device, thereby implementing the change of the form of the antenna included in the antenna module, expanding the frequency range that the antenna can cover, and achieving a better transmission effect.
For example, when the terminal needs to transmit a signal in a 5GHz band to the outside by using the first antenna in the first antenna module, the first antenna part and the second antenna part in the first antenna module can realize a resonant mode in the 5GHz band after being combined, and the terminal can control the phase change device to change from an amorphous state to a crystalline state, so as to realize the combination of the first antenna part and the second antenna part. Or, when the terminal needs to transmit a signal of a 2.5GHz band to the outside by using the first antenna in the first antenna module, after the first antenna part and the second antenna part in the first antenna module are separated, the first antenna part and the second antenna part can respectively realize a resonance mode of the 2.5GHz band, and correspondingly, the terminal can also control the phase change device to change from a crystalline state to an amorphous state, so as to realize the separation of the first antenna part and the second antenna part, and realize a working mode of working in another working band.
