FIG.1illustrates a schematic view of a top view structure of an antenna device provided in embodiments of the present application, andFIG.2illustrates a schematic view of an A-A cross-sectional view of an antenna device provided in embodiments of the present application. As shown inFIG.1andFIG.2, the antenna device includes a dielectric substrate10, a grounding metal layer20, a radiation patch30, a first feeding structure40, a first deflection patch50, and a radio frequency chip60. The dielectric substrate10may include at least one substrate layer, that is to say, the dielectric substrate10may include one substrate layer, two substrate layers, three substrate layers, or more than three substrate layers. The dielectric substrate10includes a first side and a second side opposite to the first side. The grounding metal layer20, the dielectric substrate10and the radiation patch30are stacked. The grounding metal layer20is attached to the second side of the dielectric substrate10. The radiation patch30is attached to the first side of the dielectric substrate10. The first feeding structure40penetrates through the dielectric substrate10. The first end of the first feeding structure40is connected to the radiation patch30, which defines a first connection point between the first feeding structure40and the radiation patch30. The second end of the first feeding structure40extends through the grounding metal layer20, and is electrically connected to the radio frequency chip60. A first gap is formed between the first feeding structure40and the grounding metal layer20. The radio frequency chip60is used to feed a first excitation signal to the first feeding structure40, and the first excitation signal is used to excite the radiation patch30to radiate beam. The first deflection patch50is fixed at the first side of the dielectric substrate10away from the grounding metal layer20. The first deflection patch50is positioned at a first side of the radiation patch30. The first deflection patch50can be converted from an amorphous state to a crystalline state, or from a crystalline state to an amorphous state.

In the embodiment of the present application, the first excitation signal can be fed through the first feeding structure40, and then the radiation patch30can be excited by the first excitation signal to radiate the beam, so as to implement the basic function of the antenna device. Alternatively, since the first deflection patch50can be converted from a crystalline state (metal state) to an amorphous state (insulating state), or from an amorphous state (insulating state) to a crystalline state (metal state), so that when the radiation patch30radiates beam, the first deflection patch50can be controlled to be in different states, that is, the first deflection patch50can be controlled to be in a crystalline state, or the first deflection patch50can be controlled to be in an amorphous state, so as to implement the deflection of the radiation direction of the beam, thus achieving the adjustment of the radiation direction of the beam, improves the spatial coverage of the antenna device.

In operation, when the first deflection patch50is controlled to be in the crystalline state, the radiation direction of the beam radiated by the radiation patch30excited by the first excitation signal can be deflected to one side of the first deflection patch50. When the first deflection patch50is controlled to be in the amorphous state, the radiation direction of the beam radiated by the radiation patch30excited by the first excitation signal will not be deflected. That is, as shown inFIG.3, when the first deflection patch50is in the crystalline state, the beam radiated by the radiation patch30is deflected to the first side of the radiation patch30, as shown inFIG.4, when the first deflection patch50is in the amorphous state, the beam radiated by the radiation patch30does not occur deflection. In this way, the adjustment of multiple radiation directions of the beam of the antenna device can be implemented under different requirements.

The first connection point between the first feeding structure40and the radiation patch30may be located on the center line of the radiation patch30, and a distance between the first connection point and the center point of the radiation patch30may be located within a first distance threshold range, the first distance threshold range refers to a distance range used to adjust impedance matching. That is, the impedance of the antenna device can be adjusted by adjusting the distance between the first connection point and the center point of the radiating patch30, and then the antenna matching of the antenna device can be implemented to increase radiation efficiency of the antenna device. The first connection point can be located on the center line of the radiation patch30parallel to the length direction of the first deflection patch50. Obviously, the first connection point can also be slightly offset from center line of the radiation patch30parallel to the length direction of the first deflection patch50, which is not limited in the present application.

Illustratively, the distance between the first connection point and the center point of the radiation patch30can be adjusted so that the impedance of the antenna device is 4 ohms, 5 ohms, or 6 ohms. The present application does not limit the impedance of the antenna device after adjustment.

In some embodiments, the antenna device, including the dielectric substrate10, the grounded metal layer20, the radiation patch30, and the first feeding structure40, may be a side-fire antenna or an end-fire antenna, such as a dipole antenna etc. In addition, the antenna device, including the dielectric substrate10, the grounded metal layer20, the radiation patch30, and the first feeding structure40, may be a single antenna unit or an antenna array. That is, the antenna device, including the dielectric substrate10, the grounded metal layer20, the radiation patch30, and the first feeding structure40, can be arranged in a matrix structure to obtain an antenna array. The implementation form of the antenna device, including the dielectric substrate10, the grounded metal layer20, the radiation patch30and the first feeding structure40, is not limited in the present application.

In some embodiments, because the beam radiation direction of the antenna device can be adjusted, the array antenna formed by the antenna device can not only realize the general performance of the antenna, but also realize the performance of beam scanning. Wherein, when the antenna device includes the dielectric substrate10, the grounded metal layer20, the radiation patch30, the first feeding structure40and the first deflection patch50, the first deflection patch50can be controlled to convert from an amorphous state to a crystalline state, and the beam scanning is realized by the antenna array formed by the antenna device, and the beam scanning diagram can be as shown inFIG.5.

In some embodiments, the radiation patch30may include at least one radiation sub-patch. When the radiation patch30includes two or more radiation sub-patches301, the radiation sub-patches301are stacked, the shape and size of each radiation sub-patch301are different from that of the others, or, the shape or size of each radiation sub-patch301is different from that of the others. Since each radiation sub-patch301has a different shape and size, or, each radiation sub-patch301has a different shape or size, when the radiation sub-patches301are stacked and arranged, different bandwidths corresponding to each radiation sub-patch301and mutual coupling between two radiation sub-patches301can increase the overall bandwidth of the radiation patch30, thereby increasing the bandwidth of the antenna device.

FIG.6andFIG.7illustrate some embodiments of the radiation sub-patch301, the radiation sub-patch301may have a rectangular or circular structure.

When the radiation sub-patch301has a rectangular structure, the length direction of the first deflection patch50is parallel to the first side of the radiation sub-patch301, wherein the first side edge of the radiation sub-patch is an edge of the radiation sub-patch adjacent to the first deflection patch50. In some alternative embodiments, the length direction of the first deflection patch50and the adjacent first side of the radiation sub-patch301may define a certain angle.

When the sub-radiating patch301has a circular structure, the length directions of the first deflection patch50and the radiation sub-patch301are located on the same plane.

For example, the radiation sub-patch301may be a whole-piece structure, obviously, it also be a sheet-like structure provided with through holes. For example, as shown inFIG.8, the radiation sub-patch301may be a rectangular ring structure, or as shown inFIG.9, the radiation sub-patch301may be a circular ring structure, or as shown inFIG.10, the radiation sub-patch301may be a rectangular structure provided with a cross-shaped through hole or the like.

In an embodiment, as shown inFIG.1, the first deflection patch50may be a striped rectangular structure, and the first deflection patch50may be formed by a reversible phase change material. For example, the phase change material may be vanadium dioxide, germanium antimony tellurium alloy, scandium antimony tellurium alloy or germanium antimony alloy, etc.

In some embodiments, the first deflection patch50and the radiation patch30may be located on different substrate layers of the dielectric substrate10, that is, dielectric substrate10may include a first substrate layer and a second substrate layer, at this time, the first deflection patch50is fixed on the first substrate layer of the dielectric substrate, and the radiation patch layer30is fixed on the second substrate layer of the dielectric substrate; or the first deflection patch50is fixed on the second substrate layer of the dielectric substrate, and the radiation patch30is fixed on the first substrate layer of the dielectric substrate.

In some embodiments, the first deflection patch50and the radiation patch30may be located on same substrate layer of the dielectric substrate, that is, the first deflection patch50and the radiation patch30are located at the same plane. In this way, the deflection effect of the first deflection patch50on the direction of the beam of the radiation patch30can be better improved.

For example, when the distance between the first deflection patch50and the radiation patch30approaches zero, the radiation patch30and the first deflection patch50can be approximated as one piece so that the deflection of the beam radiation direction cannot be achieved; when the distance between the first deflection patch50and the radiation patch30approaches infinity, it is equivalent to the absence of the first deflection patch50, so that the deflection of the beam radiation direction cannot be achieved. Therefore, the distance between the first deflection patch50and the radiation patch30is within a certain range, so as to better realize the deflection of the beam direction radiated by the radiation patch30. Wherein, the distance between the radiation patch30and the first deflection patch50may be in a range of about 0.2 mm to about 2 mm.

In some embodiments, the first deflection patch50can switch between the crystalline state and the amorphous state under the action of temperature, obviously, it can also switch between the crystalline state and the amorphous in other ways, such as under the action of laser excitation, the crystalline state and the amorphous state can be switched.

When the state is switched by the effect of temperature, as shown inFIG.11, the antenna device may further include a first conductive structure70, and the first conductive structure70penetrates through the dielectric substrate10, the first end of the first conductive structure70is connected to the first deflection patch50, and the second end of the first conductive structure70extends through the grounding metal layer20, and is electrically connected to an external circuit, the first conductive structure70is insulated from the grounding metal layer20, and the external circuit is used to feed a first electrical signal to the first conductive structure70, the first electrical signal is used to excite the first deflection patch50from an amorphous state to a crystalline state, or from a crystalline state to an amorphous state.

In operation, when the first deflection patch50is converted between the two states, assuming that the first deflection patch50is currently in the crystalline state, the first reflection patch50can be excited by the first electrical signal to heat up, when the temperature of the deflection patch50is not less than the temperature threshold, the excitation of the first electrical signal is stopped to achieve the rapid cooling of the first deflection patch50, so that the first deflection patch50is switched to the amorphous state. And, assuming that the first deflection patch50is currently in the amorphous state, the rust reflection patch50can be excited by the first electrical signal to heat up, when the temperature of the first deflection patch50is not less than the temperature threshold, the first electrical signal is slowly reduced to achieve the slow cooling of the first deflection patch50, so that the first deflection patch50is switched to the crystalline state.

Wherein, the temperature threshold may be determined based on the material of the first deflection patch50, and the temperature threshold refers to the temperature at which the crystal grains inside the first deflection patch50can be in a free state.

In an embodiment, as shown inFIG.12, the antenna device may further include a second deflection patch80. The second deflection patch80is located on a second side of the radiation patch30opposite to the first side of the radiation patch30, and the second deflection patch80can be converted from an amorphous state to a crystalline state, or from a crystalline state to an amorphous state.

Wherein, the second deflection patch80is fixed on the first side of the first substrate layer of the dielectric substrate10away from the grounding metal layer20. The first deflection patch50and the second deflection patch80can be located on the same substrate layer of the dielectric substrate. Alternatively, the first deflection patch50and the second deflection patch80can be located on the different substrate layers of the dielectric substrate10, for example, the first deflection patch50is fixed on the first substrate layer, and the second deflection patch80is fixed on the second substrate layer of the dielectric substrate10away from the grounding metal layer20, the second substrate layer of the dielectric substrate is a substrate layer of the dielectric substrate10which is different from the first substrate layer of the dielectric substrate10.

Wherein, the material of the second deflection patch80and the material of the first deflection patch50may be the same or similar. In some embodiments, the setting position of the second deflection patch80at the second side of the radiation patch30may be substantially corresponding to the setting position of the first deflection patch50at the first side of the radiation patch30. This will not be repeated in the application embodiments.

Wherein, the first substrate layer of the dielectric substrate may be located above the second substrate layer of the dielectric substrate, or may be located below the second substrate layer of the dielectric substrate, which is not limited in the embodiment of the present application. When the first deflection patch50and the second deflection patch80are both located on the first substrate layer of the dielectric substrate, it can be considered that the first deflection patch50and the second deflection patch80are arranged in the same layer, when the first deflection patch50is located on the first substrate layer of the dielectric substrate and the second deflection patch80is located on the second substrate layer of the dielectric substrate, it can be considered that the first deflection patch50and the second deflection patch80are arranged in different layers. In addition, the radiation patch30may be provided in the same layer as the first deflection patch50and the second deflection patch80, or may be provided in different layers, which is not limited in the embodiment of the present application.

Alternatively, when the reversible change between the crystalline state and the amorphous state of the second deflection patch80is achieved by temperature change, as shown inFIG.13, the antenna device may further include a second conductive structure90, and the location structure of the second conductive structure90may be the same or similar to that of the first conductive structure70, which will not be repeated in the embodiment of the present application.

For example, when the antenna device includes the first deflection patch50and the second deflection patch80, the first deflection patch50can be controlled to be converted from an amorphous state to a crystalline state, and the second deflection patch80can be controlled to be converted from a crystalline amorphous state to an amorphous state to achieve a beam scan by an antenna array of the antenna device, and the beam scanning diagram can be as shown inFIG.14; or the first deflection patch50can be controlled to be converted from crystalline state to amorphous state, and the second deflection patch80is controlled to be converted from an amorphous state to a crystalline state to achieve a beam scan by an antenna array c of the antenna device, and the beam scanning diagram can be as shown inFIG.15.

In some embodiments, as shown inFIG.16orFIG.17, the antenna device may further include a second feeding structure11, and the second feeding structure11penetrates through the dielectric substrate10, and the first end of the second feeding structure1I is electrically connected to the radiation patch30, which defines a second connection point between the second feeding structure40and the radiation patch30. The second end of the second feeding structure11extends through the grounding metal layer20, and is electrically connected to the radio frequency chip60. A second gap is formed between the second feeding structure11and the grounding metal layer20, and the radio frequency chip60is used to feed a second excitation signal to the second feeding structure11, and the second excitation signal is used to excite the radiation patch30to radiate radiation beam.

In this way, when the radio frequency chip60feeds the second excitation signal to the second feeding structure11, the radiation patch30can be excited by the second excitation signal to radiate the directional beam, and the radio frequency chip60can feed the first excitation signal to the first feeding structure40, under the influence of the first deflection patch50, the feeding structure40excites the beam with adjustable radiation direction of the radiation patch30through the first excitation signal.

For example, the second feeding structure11may be provided when the antenna device includes the radiation patch30and the first deflection patch50, or the second feeding structure11may be provided when the antenna device includes radiation patch30, the first deflection patch50and the second deflection patch80.

In some embodiments, when the second deflection patch80is fixed on the first side of the first substrate layer of the dielectric substrate away from the grounding metal layer20, the third deflection patch12is fixed on the side of the first substrate layer of the dielectric substrate or the third substrate layer of the dielectric substrate away from the grounded metal layer20, that is, the first deflection patch50, the second deflection patch80, and the third deflection patch12are located on the same substrate layer of the dielectric substrate, or the first deflection patch50and the second deflection patch80are located on the same substrate layer of the dielectric substrate, and the third deflection patch12is located on another layer of dielectric substrate.

In this way, when the second excitation signal is fed through the second feeding structure11excites the radiation beam of the radiation patch30, the third deflection patch12can be controlled to be in different states, that is, the third deflection patch12can be controlled to be in a crystalline state, or the third deflection patch12can be controlled to be in an amorphous state, so as to implement the deflection of the radiation direction of the beam.

In the actual embodiment process, when the third deflection patch12is in the crystalline state, the radiation direction of the beam radiated by the radiation patch30excited by the second excitation signal can be deflected to towards the side where the third deflection patch12is located, that is, towards the third side of the third radiation patch; when the third deflection patch12is in the amorphous state, the radiation direction of the beam radiated by the radiation patch30excited by the second excitation signal will not be deflected. In this way, the adjustment of multiple radiation directions of the beam of the antenna device can be implemented under different requirements.

Wherein, the positional relationship between the first substrate layer of the dielectric substrate and the third substrate layer of the dielectric substrate may not be limited, and the first deflection patch50, the second deflection patch80, and the third deflection patch12may be located on the same substrate layer of the dielectric substrate or on the different substrate layers of the dielectric substrate based on the set position, which are not limited in the embodiment of the present application.

The fourth dielectric substrate is one substrate layer of the dielectric substrate of at least one dielectric substrate10that is different from the first dielectric substrate, the second dielectric substrate, and the third dielectric substrate.

For example, when the antenna device includes a first deflection patch50, a second deflection patch80, a third deflection patch12, and a fourth deflection patch14, the first deflection patch50, the second bias The sheet80, the third deflection patch12, the fourth deflection patch14and the radiation patch30can be fixed to the same substrate layer of the dielectric substrate, that is, the first deflection patch50, the second deflection patch80, the third deflection patch12, the fourth deflection patch14, and the radiation patch30may be located one the same plane, which is not limited in the embodiment of the present application.

Illustratively, when the second feeding structure11feeds the excitation signal, the fourth deflection patch14is in a crystalline state, and the third deflection patch12is in an amorphous state, regardless of the state of the first deflection patch50and the second deflection patch80, the main beam of the antenna is deflected in the direction of the fourth deflection patch14. When the second feeding structure11feeds the excitation signal, the fourth deflection patch14is in an amorphous state, and the third deflection patch12is in a crystalline state, regardless of the state of the first deflection patch50and the second deflection patch80, the main beam of the antenna is deflected in the direction of the third deflection patch12. And, when the second feeding structure11feeds the excitation signal, the fourth deflection patch14and the third deflection patch12are in the same state, the main beam of the antenna is not deflected, usually in the side firing direction.

When the first feeding structure40feeds the excitation signal, the first deflection patch50is in a crystalline state, and the second deflection patch80is in an amorphous state, regardless of the state of the fourth deflection patch14and the third deflection patch12, the main beam of the antenna is deflected in the direction of the first deflection patch50. When the first feeding structure40feeds the excitation signal, the first deflection patch50is in an amorphous state, and the second deflection patch80is in a crystalline state, regardless of the state of the fourth deflection patch14and the third deflection patch12, the main beam of the antenna is deflected in the direction of the second deflection patch50. And, when the first feeding structure40feeds the excitation signal, the first deflection patch50and the second deflection patch80are in the same state, the main beam of the antenna is not deflected, usually in the end firing direction.

In some embodiments, the single-polarized antenna may be formed by the first feeding structure40and the radiation patch30, obviously, the antenna device may further include a third feeding structure, and the third feeding structure penetrates through the dielectric substrate10, and the first end of the third feeding structure is connected to the radiation patch30, which defines a third connection point between the third feeding structure40and the radiation patch30. The second end of the third feeding structure extends through the grounding metal layer20, a third gap is formed between the third feeding structure and the grounding metal layer20. The third feeding is used to feed the third excitation signal, and the third excitation signal is used to excite the radiation patch30to radiate beam.

In this way, when the radiation patch30is excited by the first excitation signal and the third excitation signal respectively fed through the first feeding structure40and the third feeding structure, the dual-polarized antenna can be realized, and thus the deflection of the beam radiation direction of the dual-polarized antenna can be achieved by the first deflection patch50.

Wherein, a third connection point between the third feeding structure and the radiation patch30and the first connection point form center symmetry with the center point of the radiation patch30.

In some embodiments, the single-polarized antenna may be formed by the second feeding structure11and the radiation patch30, obviously, the antenna device may further include a fourth feeding structure, and the fourth feeding structure penetrates through the dielectric substrate10, and the first end of the fourth feeding structure is connected to the radiation patch30, which defines a fourth connection point between the fourth feeding structure40and the radiation patch30. The second end of the fourth feeding structure extends through the grounding metal layer20, and is electrically connected to the radio frequency chip60. A fourth gap is formed between the fourth feeding structure and the grounding metal layer20. The fourth feeding structure is used to feed the fourth excitation signal, and the fourth excitation signal is used to excite the radiation patch30radiation beam.

In this way, when the radiation patch30is excited by the second excitation signal and the fourth excitation signal respectively fed through the second feeding structure11and the fourth feeding structure, the dual-polarized antenna can be realized, and thus the deflection of the beam radiation direction of the dual-polarized antenna can be achieved by the third deflection patch12and the fourth deflection patch14.

Wherein, the fourth connection point between the fourth feeding structure and the radiation patch30and the second connection point form center symmetry with the center point of the radiation patch30.

In the embodiment of the present application, the first excitation signal and the second excitation signal can be fed through the first feeding structure and the second feeding structure respectively, and then the radiation patch can be excited by the first excitation signal and the second excitation signal to radiate the beam, so as to implement the basic function of the antenna device. Alternatively, since the first deflection patch, the second deflection patch, the third deflection patch, and the fourth deflection patch can all be converted from a crystalline state to an amorphous state, or from an amorphous state to a crystalline state, that is, the four deflection patches can all be converted from a metal state to an insulating state, or from an insulating state to a metal state, so that when the radiation patch radiation beam is excited by the first excitation signal and the second excitation signal, the first deflection patch and the second deflection patch can be controlled to be in different states, and the third deflection patch and the fourth deflection patch can be controlled to be in different states. That is, the first deflection patch can be controlled to be in the crystalline state and the second deflection patch can be controlled to be in the amorphous state, or, the first deflection patch is in the amorphous state, and the second deflection patch is in the crystalline state, and the third deflection patch can be controlled to be in the crystalline state and the fourth deflection patch can be controlled to be in the amorphous state, or the third deflection patch is in the amorphous state and the fourth deflection patch is in the crystalline state, thus achieving the adjustment of the radiation direction of the beam, improves the spatial coverage of the antenna device.
