Specifically, when the antenna unit 100 is controlled to send a beam, the radio-frequency signal is provided to the power feeder 31 in each phase shifting unit 30 through the radio-frequency signal terminal 50, a grounding signal is provided to the grounding electrode 33 in each phase shifting unit 30 through a grounding signal end, and the driver circuit 40 provides a control signal to the drive electrode 34 in each phase shifting unit 30. The Liquid Crystal Polymer in each phase shifting unit 30 is deflected by an electric field formed by the drive electrode 34 and the grounding electrode 33, so that the dielectric constant of the liquid crystal polymer is changed, and the radio-frequency signal transmitted in the power feeder 31 is phase-shifted. The phase-shifted radio frequency signal is radiated through the radiator 32 in the phase shifting unit 30, and a radio-frequency signals radiated by the phase shifting units 30 interfere to form a beam having a main lobe direction, to satisfy the performance requirements of the antenna unit 100.
For one phase shifting unit 30, the driver circuit 40 provides different control signals to the drive electrode 34, and the electric field form by the drive electrode 34 and the grounding electrode 33 drives the liquid crystal polymer to deflect, so that the liquid crystal polymer may have different dielectric constants, and then the phase shifting unit 30 performs shifting the phase for the radio-frequency signal to different extents, that is, in the embodiment of the present disclosure, the phase shifting unit 30 is a phase shifting unit whose control signal voltage is variable, and one phase shifting unit 30 can radiate radio-frequency signals having a phases. Thus, by adjusting the phase of the radio-frequency signals radiated by the phase shifting unit 30, when the radio-frequency signals radiated by the phase shifting units 30 interfere with each other, the direction of the main lobe of the final formed beam can be adjusted.
The radiator 32 in the phase shifting unit 30 can radiate and receive signals. When the radiator 32 receives the radio-frequency signal, the liquid crystal polymer in the phase shifting unit 30 controls the phase shifting of the radio-frequency signal, and the phase shifted radio-frequency signal is transmitted to the radio-frequency signal terminal 50 via the power feeder 31, and outputted via the radio-frequency signal terminal 50.
As shown in
It can be understood that this is an embodiment, but limitations would not be made thereto. In some embodiments, the grounding electrode 33 and the power feeder 31 may be disposed in a same layer, the radiator 32, the power feeder 31 and the grounding electrode 33 are all disposed on a surface of a first substrate 10 facing a second substrate 20, and the drive electrode 34 is disposed on a surface of the second substrate 20 facing the first substrate 10. The performance requirement of the antenna unit 100 can also be satisfied. At the same time, the power feeder 31, the radiator 32 and the grounding electrode 33 are all disposed on a surface of the first substrate 10 facing the second substrate 20, so that in the process flow of forming the power feeder 31, the radiator 32 and the grounding electrode 33, merely one layer of metal, such as one layer of copper, is evaporated on the surface of the first substrate 10, and then the power feeder 31, the radiator 32 and the grounding electrode 33 can be etched by using one mask process, thus simplifying the process flow and reducing the manufacturing cost.
In some embodiments, the antenna unit 100 and the antenna apparatus provided in the embodiment of the present disclosure further include a power feeder line 36, a first substrate 10 of each antenna unit 100 is provided with the power feeder line 36, and power feeders 31 of a phase shifting units 30 of a same antenna unit 100 are electrically connected to a same radio-frequency signal terminal 50 through the power feeder line 36. Thus, the radio frequency signal supplied from the radio frequency signal end 50 is transmitted to the power feeder 31 of each phase shifting unit 30 via the power feeder line 36, to ensure the normal operation of each phase shifting unit 30. Moreover, with this arrangement, merely one radio-frequency signal terminal 50 is provided in the antenna unit 100 to transmit radio-frequency signals to the power feeder 31 of each phase shifting unit 30, to reduce the number of radio-frequency signal terminals 50 required to be provided and further reducing the manufacturing cost of the antenna unit 100.
As an embodiment, the antenna unit 100 provided in the embodiment of the present disclosure further include a control signal lines 37, the control signal lines 37 are disposed on the second substrate 20, and the drive electrode 34 of each phase shifting unit 30 of the same antenna unit 100 is connected to the driver circuit 40 of the same antenna unit 100 through one control signal line 37. Based on this arrangement, the control signals received by the phase shifting units 30 are independent of each other. By controlling the phase shifting of the radio-frequency signal by each phase shifting unit 30, the accuracy of adjusting the main lobe direction of the beam formed by the antenna unit 100 can be improved.
In some embodiments, a driver circuit 40 of each antenna unit 100 includes a flexible circuit board, the flexible circuit board includes a control signal terminals, and the control signal terminals are electrically connected to the control signal lines 37 in one-to-one correspondence. In one embodiment, a transmission path of the control signal is formed between the control signal line 37, the drive electrode 34 and the control signal end of the flexible circuit board to ensure that the control signal is transmitted to the drive electrode 34, to ensure that an electric field is formed between the drive electrode 34 and the grounding electrode 33 to drive the liquid crystal polymer to deflect and shift the phase of the radio frequency signal.
As an embodiment, in the antenna unit 100 provided in the embodiment of the present disclosure, an orthographic projection of the phase shifting region 20a on the plane where the first substrate 10 is located is in a shape of a polygon, an orthographic projection of the first step region 12 on the plane where the first substrate 10 is located starts from one edge of the polygon and protrudes along the first direction X and away from the polygon, and an orthographic projection of the second step region 22 on the plane where the first substrate 10 is located starts from another edge of the polygon and protrudes along the second direction Y and away from the polygon. In other words, a shape of an orthographic projection of the first body region 11 on the plane where the first substrate 10 is located and a shape of an orthographic projection of the second body region 21 on the plane where the first substrate 10 is located are same and polygonal. A direction in which the first step region 12 protrudes from the phase shifting region 20a is different from a direction in which the second step region 22 protrudes from the phase shifting region 20a and the included angle between the two directions is smaller than 180°.
With the above arrangement, the connection and control requirements between the driver circuit 40, the radio-frequency signal terminals 50 and the phase shifting units 30 can be achieved. With the above arrangement, the first step region 12 of the antenna unit 100 and the second step region 22 of the antenna unit 100 may be provided on adjacent sides, so that when the antennas are spliced, regions where edges of the phase shifting regions 20a in which the first step region 12 and the second step region 22 are not provided are located can be spliced with each other. This arrangement enables the antenna units 100 to be spliced in a directions, to increase the number of antenna units 100 included in the antenna apparatus under the condition of the same length size and/or width size, achieve a multi-radiator 32 arrangement and improve the gain of the antenna apparatus.
In some embodiments, in the antenna unit 100 provided in the embodiment of the present disclosure, each edge of the polygon presented by the orthographic projection of the phase shifting region 20a on the plane where the first substrate 10 is located is equal in length. The above arrangement facilitates the connection and control among the radio-frequency signal terminal 50, the driver circuit 40 and each phase shifting unit 30. At the same time, since each edge of the polygon presented by the orthographic projection of the phase shifting region 20a on the plane where the first substrate 10 is located is equal in length, the phase shifting regions 20a of the antenna units 100 are facilitated to be spliced with each other when the antenna units 100 are spliced to form the antenna device.
As an embodiment, when each edge of the polygon presented by the orthographic projection of the phase shifting region 20a on the plane where the first substrate 10 is located is equal in length, the polygon may be made to be a rhombus or a regular polygon to satisfy the splicing requirement between the antenna units 100.

The first edge aa, the second edge bb, the third edge cc, and the fourth edge dd are arranged in succession, two adjacent edges are connected and perpendicular to each other, and the first edge aa, the second edge bb, the third edge cc, and the fourth edge dd together form a regular quadrangle.
The orthographic projection of the first step region 12 on the plane where the first substrate 10 is located starts from the first edge aa of the regular quadrangle and protrudes along the first direction X and away from the regular quadrangle, and the orthographic projection of the second step region 22 on the plane where the first substrate 10 is located starts from the second edge bb of the regular quadrangle and protrudes along the second direction Y and away from the regular quadrangle. The shape of the orthographic projection of the first step region 12 on the plane where the first substrate 10 is located and the shape of the orthographic projection of the second step region 22 on the plane where the first substrate 10 is located are rectangles. With the above arrangement, four antenna units 100 may be arranged in two rows and two columns by splicing four antenna units 100 with each other. Among two antenna units 100 spliced with each other, a region where a third edge cc of one antenna unit 100 is located and a region where a fourth edge dd of the other antenna unit 100 is located can be butted with each other to ensure the butting between the antenna units 100 and improve the gain of the formed antenna apparatus.

In an embodiment, at least one end of the second step region 22 along an extending direction of an edge where the second step region 22 is located is provided with an oblique angle 20b. With the above arrangement, stress concentration at a connection position between the second step region 22 and the second body region 21 of the second substrate 20 can be reduced, and the safety performance of the antenna unit 100 can be further improved.
