In the embodiment of the present application, the structure of the body 100 is not limited. For example, the body 100 may have a strip structure or a block structure. As an example, as shown in fig. 1, the body 100 has a rectangular parallelepiped structure.
Here, the body 100 is used for a dielectric substrate. The material of the body 100 is not limited as long as the dielectric loss can be reduced and the reflection gain of a large-scale antenna signal can be increased. For example, the material of the body 100 may be silicon dioxide.
Here, the thickness of the body 100 is not limited. For example, the thickness of the body 100 has a value ranging from 450um to 550um. As an example, the thickness of the body 100 has a value of 500um.
It should be noted that the thickness of the body 100 refers to a thickness formed between a surface opposite to the first surface of the body 100 and the first surface of the body 100, as indicated by H in fig. 1 as the thickness of the body 100.
In the present embodiment, the working layer 200 is used for large-scale antenna radiation.
In the embodiment of the present application, the cross-sectional shape of the conductive ring 210 is not limited. For example, the conductive ring 210 may have a circular ring-shaped cross-sectional shape. For another example, as shown in fig. 1, the cross-sectional shape of the conductive ring 210 may also be a square-shaped structure, in which case, the inner frame and the outer frame of the conductive ring 210 may be both rectangular.
Here, the thickness of the conductive ring 210 is not limited. For example, the thickness of the conductive ring 210 has a value in the range of 0.1um to 0.3um. As an example, the thickness of the conductive ring 210 has a value of 0.2um.
It should be noted that the thickness direction of the conductive ring 210 is substantially the same as the thickness direction of the body 100.

The thickness of the phase change portion 220 is substantially the same as the thickness of the conductive ring 210.
Here, the material of the phase change portion 220 is vanadium dioxide, and in this case, the phase change portion 220 is sensitive to temperature, and the electrical conductivity of the phase change portion 220 is greatly changed under the external temperature excitation.
As shown in fig. 7, a vanadium dioxide film with a thickness of 0.2um is formed by a vanadium dioxide material through a magnetron sputtering method, and when the temperature is increased to about 60 ℃, the conductivity of the vanadium dioxide film can reach 10000 siemens per meter (S/m); so that the conducting state of the conducting ring 210 is rapidly changed through the phase change portion 220 of the vanadium dioxide material.
When the conductive ring 210 is energized, the phase change portion 220 forms a capacitance structure at the opening 211, the temperature of the phase change portion 220 increases, and the phase change portion 220 can be transformed from an insulating state to a conductive state, so that the conductive ring 210 is transformed from an open state to a closed state.
In the embodiment of the present application, the power-on states of the conductive loops 210 of the at least two working layers 200 are programmed to control the large-scale antenna to be at different radiation angles by programming the conductive loops 210 of the at least two working layers 200 to be at different on-states or off-states.
Here, the power-on states of the at least two working layers 200 correspond to radiation angles of the large-scale antenna; under the condition that the energization states of the working layers 200 of the at least two working layers 200 are different, the radiation angles of the large-scale antenna are different, and at this time, the radiation angles of the large-scale antenna can be controlled by controlling the energization states of the working layers 200 of the at least two working layers 200.

For example, the value of the spacing between adjacent working layers 200 in the at least two working layers 200 ranges from 20um to 30um. As an example, the spacing between adjacent working layers 200 in the at least two working layers 200 has a value of 25um.
In some optional implementations of embodiments of the present application, the conductive ring 210 may include: a first wall portion 212 and a second wall portion 213. The first wall portion 212 is strip-shaped, the first wall portion 212 is attached to the first surface of the body 100 in the first direction, and the opening 211 is formed in the first wall portion 212; both ends of the second wall 213 are connected to both ends of the first wall 212, respectively, and the second wall 213 and the first wall 212 form a ring structure.
In the present embodiment, the cross-sectional shape of the first wall portion 212 is not limited. For example, the first wall portion 212 may have a straight strip structure. For another example, as shown in fig. 1, the cross-sectional shape of the first wall portion 212 may be rectangular. Of course, the first wall portion 212 may have a curved structure.
Here, the specific direction of the first direction is not limited. For example, the at least two working layers 200 are spaced apart in a first direction on the first surface of the body 100, that is, the first wall 212 is disposed in the same direction as the at least two working layers 200 are spaced apart. As an example, the first direction is the a direction shown in fig. 1.
In the present embodiment, the cross-sectional shape of the second wall portion 213 is not limited. For example, the cross-sectional shape of the second wall portion 213 may be a C-shaped structure.
Here, the width of the second wall portion 213 and the width of the first wall portion 212 may be the same or different.
As an example, the second wall portion 213 and the first wall portion 212 form a zigzag structure; at this time, the inner frame of the loop-shaped conductive loop 210 may be substantially rectangular, and the outer frame of the loop-shaped conductive loop 210 may be substantially rectangular.
Here, the length of the inner frame in the zigzag structure in the first direction may be smaller than the length of the inner frame in the zigzag structure in the second direction, as shown in fig. 1. As an example, the length of the inner frame in the square-shaped structure in the first direction is 120um, and the length of the inner frame in the square-shaped structure in the second direction is 175um.
Here, the second direction and the first direction may satisfy a perpendicular condition, that is, the second direction and the first direction are perpendicular or substantially perpendicular.

In the present implementation, the cross-sectional shape of the first connection part 230 is not limited. For example, the first connection portion 230 may have a strip structure. As an example, the first connection part 230 has a rectangular cross-sectional shape.
Here, the thickness of the first connection part 230 is not limited. For example, the thickness of the first connection portion 230 is substantially equal to the thickness of the conductive ring 210.
Here, the material of the first connection part 230 is not limited. For example, the material of the first connection portion 230 is gold, so as to ensure that the first connection portion 230 has extremely high stability in air and low oxidation; meanwhile, the performance stability and the service life of the large-scale antenna can be effectively ensured.
In the present embodiment, the cross-sectional shape of the second connection portion 240 is not limited. For example, the second connection portion 240 may have a stripe structure. As an example, the cross-sectional shape of the second connection part 240 is a rectangle.

Here, the material of the second connection part 240 is not limited. For example, the material of the second connection portion 240 is gold, so as to ensure that the second connection portion 240 has extremely high stability under air and low oxidation; meanwhile, the performance stability and the service life of the large-scale antenna can be effectively ensured.
As an example, in the case that the conductive ring 210 includes a first wall portion 212 and a second wall portion 213, a first connection portion 230 is attached to the first surface of the body 100 in the second direction, the first connection portion 230 is connected to a first end of the first wall portion 212, and a first gap is formed between the first connection portion 230 and the second wall portion 213; the second connecting portion 240 is attached to the first surface of the body 100 in the second direction, the second connecting portion 240 is connected to the second end of the first wall portion 212, and a second gap is formed between the second connecting portion 240 and the second wall portion 213; the second end of the first wall portion 212 is disposed opposite the first end of the first wall portion 212.
Here, the second direction is not limited. For example, as shown in fig. 2, the at least two working layers 200 are spaced apart in a first direction a on a first surface of the body 100; the second direction and the first direction may satisfy a vertical condition.
Here, a portion of the first connection portion 230 connected to the first end of the first wall portion 212 may be the same as the width of the first wall portion 212, or may be the same as the width of the first connection portion 230.
The portion of the second connecting portion 240 connected to the second end of the first wall portion 212 may have the same width as the first wall portion 212, or may have the same width as the second connecting portion 240.
It should be noted that the width of the first connection portion 230 refers to the length of the first connection portion 230 in the first direction, and the width of the second connection portion 240 refers to the length of the second connection portion 240 in the first direction.
The width of the first wall portion 212 is defined as the width from the inner frame of the conductive ring 210 to the outer frame of the conductive ring 210, and the width of the second wall portion 213 is defined as the width from the inner frame of the conductive ring 210 to the outer frame of the conductive ring 210.
In an example, a first partial working layer of the at least two working layers 200 is spaced apart from the first surface of the body 100 in a first direction; the conductive loop 210 of the first partial operation layer is programmed to provide a plurality of operation layers 200 spaced apart from each other in a first direction for a large-scale antenna. A second partial working layer of the at least two working layers 200 is disposed on the first surface of the body 100 in a second direction; adjacent working layers 200 in the second partial working layer are connected by the first connection portion 230 and the second connection portion 240, so that the large-scale antenna is provided with a plurality of interconnected working layers 200 in the second direction; thereby enabling the large-scale antennas to form an antenna array; meanwhile, because the adjacent working layers 200 in the second partial working layer are connected through the first connection part 230 and the second connection part 240, the same row of working layers 200 in the array can be simultaneously heated, and the complexity of a large-scale antenna heating structure is greatly reduced.
In example one, the power-on state of the conductive loop 210 of the first partial operating layer is programmed to control the large-scale antenna to be at different radiation angles by programming the conductive loop 210 of the first partial operating layer to be at different on-states or off-states.
In example one, the number of the first partial working layers is not limited. For example, as shown in FIG. 3, the first partial operational layer may include 9 rows of operational layers 200.
In example one, the number of the second partial working layers is not limited. For example, as shown in FIG. 3, each row of working layers 200 of the first partial working layer includes 9 working layers 200. That is, the massive antennas form an antenna array of 9 rows and 9 columns.
In example one, as shown in fig. 4, if the voltages applied to each row of the working layer 200 in fig. 3 are labeled as V1, V2, V3, V4, V5, V6, V7, V8, and V9 in sequence. V1, V2, V3, V7, V8, V9 are not energized, and V4, V5 and V6 are energized at the same voltage. At this time, the radiation angle of the large-scale antenna is negative 30 degrees and positive 30 degrees, as shown in fig. 10.
It should be noted that each row of the working layer 200 is connected to a set voltage at one end and to ground at the other end.
As another example, the first partial operation layer includes 12 rows of operation layers 200, and voltages applied to each row of operation layers 200 are sequentially labeled as V1, V2, V3, V4, V5, V6, V7, V8, V9, V10, V11, and V12. V1, V2, V3, V4, V9, V10, V11, V12 are not energized, and V5, V6, V7 and V8 are energized. At this time, the radiation angle of the large-scale antenna is negative 22 degrees and positive 22 degrees, as shown in fig. 11.
At this time, the conduction voltage of the first partial working layer corresponding to the radiation angle of the large-scale antenna is controlled by programming, so that the radiation angle of the large-scale antenna can be controlled.
In example one, as shown in fig. 3 and 2, the conductive loop 210, the phase change part 220, the first connection part 230, the second connection part 240 and portions of the body 100 form an antenna unit, that is, a large-scale antenna is formed of at least two antenna units.
Of course, in the case that the working layer 200 includes the conductive loop 210 and the phase change portion 220, the conductive loop 210, the phase change portion 220 and the portion of the body 100 form an antenna unit, as shown in fig. 1.
Here, as shown in fig. 5 and 6, the single antenna body has a first length in the first direction a, and the single antenna body has a second length in the second direction B.
The value of the first length is not limited. For example, the first length has a value ranging from 200um to 400um. As an example, the first length has a value of 320um.
The value of the second length is not limited. For example, the second length has a value ranging from 200um to 400um. As an example, the second length has a value of 320um.
As an example, the first length has a value of 320um, the second length has a value of 320um, and at this time, the single antenna can radiate a beam of 0.218 terahertz (THz), and the phase change unit 220 has a phase difference of approximately 180 degrees in the case of the phase change of the beam of 0.218 terahertz (THz), as shown in fig. 9. Meanwhile, as shown in fig. 8, the same reflection amplitude ensures the accuracy of snell's law used in the antenna-unit control of the terahertz wave beam.
It should be noted that, according to snell's law, when the phase gradient condition of the terahertz antenna is satisfied, the deflection function of the terahertz beam can be realized.
The value of the first length may be equal to the value of the second length. Of course, the value of the first length may not be equal to the value of the second length.
In some optional implementations of embodiments of the present application, the large-scale antenna may further include: and a reflective layer. The reflective layer is attached to the second surface of the body 100; the second surface and the first surface are back-to-back; so that the massive antenna forms a reflector antenna by means of the reflective layer.
In this implementation, the material of the reflective layer is not limited as long as it has a reflective function. For example, the material of the reflecting layer is gold so as to ensure that the reflecting layer has extremely high stability in air and has low oxidizability; meanwhile, the performance stability and the service life of the large-scale antenna can be effectively ensured.
In this implementation, the degree of layering of the reflective layer is not limited. For example, the reflective layer has a thickness greater than 0.1um. As an example, the thickness of the reflective layer is 0.2um.
The large-scale antenna in the embodiment of the present application includes a body 100; at least two working layers 200, said working layers 200 comprising: a conductive ring 210 attached to the first surface of the body 100, having conductivity, and having an opening 211; a phase change portion 220 filled in the opening 211; the at least two working layers 200 are spaced apart on the first surface of the body 100; the power-on states of the conductive rings 210 of the at least two working layers 200 are controlled by programming; the phase change portion 220 is made of vanadium dioxide, and when the conductive ring 210 is energized, the phase change portion 220 can be converted from an insulating state to a conductive state; since the phase change portion 220 is only filled in the opening 211 of the conductive ring 210, the phase change time of the phase change portion 220 can be greatly shortened under the same power-on condition, and the working efficiency of the large-scale antenna can be improved.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
