Referring to fig. 10 and 11, when the conductive slider 34 and the first conductive runner 32 are located on different planes, the first conductive runner 32 is located on the first surface 105, and the conductive slider 34 is located on the second surface 106 or a surface opposite to the second surface 106. The present embodiment is described by taking the conductive slider 34 on the second surface 106 as an example. The second end 332 of the conductive shaft 33 extends through the first surface 105 and is electrically connected to the main feed port 30. The first end 331 of the conductive shaft 33 penetrates the second surface 106 and is electrically connected to one end of the conductive slider 34. The other end of the conductive runner 34 extends towards the side of the first conductive runner 32. The orthographic projection of the conductive slider 34 on the plane of the first conductive slideway 32 at least partially coincides with the area of the first conductive slideway 32. For convenience of description, the overlapping portion 342 is defined as a portion where an orthographic projection of the conductive slider 34 on the plane of the first conductive slideway 32 and the first conductive slideway 32 overlap. The overlap 342 is coupled to the first conductive runner 32. The overlap 342 separates the first conductive runner 32 into a first runner portion 321 and a second runner portion 322. The first ramp portion 321 is located between the first feeder port 41 and the overlap 342, and the second ramp portion 322 is located between the second feeder port 42 and the overlap 342. In this embodiment, the conductive shaft 33, the conductive sliding piece 34 and the first sliding path portion 321 form a first phase shift branch 311. The conductive shaft 33, the conductive slider 34, and the second runner portion 322 form a second phase shift branch 312.
Referring to fig. 6, the array antenna assembly 10 further includes a driving member 5. The drive 5 may be a micro motor or the like.
Referring to fig. 6, the shaft of the driving member 5 is connected to the conductive shaft 33. Specifically, the rotation axis of the driving member 5 is also along the Z-axis direction. The driving member 5 is connected to a side of the conductive rotating shaft 33 away from the first conductive slideway 32. The driver 5 is located on the second surface 106 side of the second insulating dielectric substrate 104. When the conductive sliding piece 34 and the first conductive sliding way 32 are located on the same surface, the driving member 5 is connected to the second end 332 of the conductive rotating shaft 33. When the conductive sliding piece 34 and the first conductive sliding way 32 are located on different planes, the driving member 5 is connected to the first end 331 of the conductive rotating shaft 33.
The driving member 5 is used for driving the conductive rotating shaft 33 to rotate around the Z axis to drive the conductive sliding piece 34 to slide along the first conductive sliding way 32, so as to adjust the length of the conductive path between the conductive rotating shaft 33 and the first antenna unit 111 and the length of the conductive path between the conductive rotating shaft 33 and the second antenna unit 112. The length of the conductive path between the conductive rotating shaft 33 and the first antenna element 111 is an effective length of current flowing from the end of the conductive rotating shaft 33 electrically connected with the main feed port 30 to the first branch feed port 41. The length of the conductive path between the conductive shaft 33 and the second antenna element 112 is the effective length for current to flow from the end of the conductive shaft 33 electrically connected to the main feed port 30 to the second feed port 42.
By driving the conductive slider 34 to slide along the first conductive slideway 32, the length of the first slideway section 321 and the length of the second slideway section 322 can be changed, in particular, the length of the first slideway section 321 is decreased and the length of the second slideway section 322 is increased, or the length of the first slideway section 321 is increased and the length of the second slideway section 322 is decreased; so as to change the length of the conductive path from the main feed port 30 to the first branch feed port 41 and also change the length of the conductive path from the main feed port 30 to the second branch feed port 42, so that the phase of the signals radiated by the first antenna element 111 and the second antenna element 112 is adjustable, and the signals radiated by the first antenna element 111 and the second antenna element 112 are shaped into a beam and form a pattern with higher gain.
It is understood that the driver 5 may be electrically connected to the main board 200 of the electronic device 1000 through an electrical connector. The main board 200 is provided with a control chip (not shown) for electrically connecting the driving member 5 to start the rotation of the rotating shaft of the driving member 5, so as to drive the conductive sliding piece 34 to rotate.
By designing the phase shifting network 3 between the first antenna element 111 and the second antenna element 112 and the total feed port 30 of the rf transceiver chip 20, by designing the phase shift network 3 to include a conductive sliding piece 34 driven by the driving member 5 and a first conductive sliding track 32 connected to the feeding port of the first antenna element 111 and the feeding port of the second antenna element 112, by driving the conductive slider 34 to rotate, the conductive slider 34 can move along the first conductive sliding way 32, so as to adjust the length of the first conductive slideway 32 on both sides of the conductive sliding piece 34, adjust the length of the conductive path between the conductive rotating shaft 33 and the second antenna unit 112, and adjust the length of the conductive path between the conductive rotating shaft 33 and the third antenna unit 113, the phases of the signals radiated by the first antenna unit 111 and the second antenna unit 112 are adjustable, and the beam of the signals radiated by the first antenna unit 111 and the second antenna unit 112 is shaped and the beam scanning angle is flexibly changed.
Referring to fig. 12, the array antenna assembly 10 further includes a phase compensation network 6. The phase compensation network 6 comprises at least a first phase compensator 61 and a second phase compensator 62. The first phase compensator 61 is electrically connected to the first shunt port 41 of the first antenna element 111 and one end of the first conductive slideway 32, and the first phase compensator 61 is used for performing phase compensation on a signal radiated by the first antenna element 111. The second phase compensator 62 is electrically connected to the first feeding port 41 of the second antenna unit 112 and the other end of the first conductive slideway 32, and the second phase compensator 62 is used for performing phase compensation on the signal radiated by the second antenna unit 112. In this embodiment, the conductive lengths of the first phase compensator 61 and the second phase compensator 62 are fixed, so the compensation value of the first phase compensator 61 for the phase is fixed. In other embodiments, the first phase compensator 61 and the second phase compensator 62 may also be phase-adjustable phase compensators, for example, a switch may be provided in the first phase compensator 61 (or the second phase compensator 62), and the switch may be turned off or on under different conditions.
Alternatively, the first phase compensator 61 may be a microstrip line, a conductive via, or the like. The second phase compensator 62 may be a microstrip line, a conductive via, or the like.
Optionally, referring to fig. 13, the phase compensation network 6 may be disposed between the first insulating dielectric substrate 101 and the second insulating dielectric substrate 104. The array antenna assembly 10 further includes a third insulating dielectric substrate 107 stacked between the first insulating dielectric substrate 101 and the second insulating dielectric substrate 104. The third insulating dielectric substrate 107 includes third and fourth oppositely disposed surfaces 108 and 109. The third surface 108 faces the second face 103. The fourth surface 109 faces the first surface 105. The phase compensation network 6 may be provided on the third surface 108. Alternatively, the phase compensation network 6 may be a microstrip line.
The electrical connection between the phase compensation network 6 and the array antenna 1 is electrically connected or coupled through conductive vias. The electrical connection between the phase compensation network 6 and the phase shift network 3 is electrically connected or coupled by conductive vias.
When the length of the conductive path between the main feed port 30 and the first sub-feed port 41 needs to be long, and the length is provided by the first conductive slideway 32 only, the space occupied by the first conductive slideway 32 is large, which is not favorable for miniaturization of the array antenna assembly 10. Based on this, by arranging the first phase compensation piece 61 on the first conductive slide 32, the first phase compensation piece 61 may be located at a different layer from the first conductive slide 32, so as to reduce the space occupied by the first conductive slide 32, and the function of the second phase compensation piece 62 may refer to the function of the first phase compensation piece 61, which is not described herein again.
Alternatively, the conductive length of the first phase compensator 61 and the conductive length of the second phase compensator 62 may be the same or different. The "conductive length" of the first phase compensator 61 is the length that is switched in between the first conductive slide 32 and the first shunt port 41. The "conductive length" of the second phase compensator 62 is the length that taps between the first conductive runner 32 and the second feed-through port 42.
In this embodiment, the conductive length of the first phase compensator 61 is equal to the conductive length of the second phase compensator 62. Thus, by driving the conductive sliding piece 34 to slide, the phases of the signals fed into the first antenna unit 111 and the second antenna unit 112 can be changed, and the phase shift value thereof also forms a mapping relationship with the rotation angle of the conductive sliding piece 34.
The phase shift network 3 provided in the second embodiment of the present application is specifically described below with reference to the drawings. The present embodiment is substantially the same as implementing a phase shift network 3 provided, and the main differences are as follows:
referring to fig. 14, the array antenna 1 further includes a third antenna unit 113. The third antenna unit 113 is disposed between the first antenna unit 111 and the second antenna unit 112, and is spaced apart from the first antenna unit 111 and the second antenna unit 112. Specifically, the first antenna element 111, the third antenna element 113, and the second antenna element 112 are sequentially arranged in the X-axis direction. The shapes and sizes of the first antenna element 111, the third antenna element 113, and the second antenna element 112 are not specifically limited in the present application. Meanwhile, the shapes of the first antenna element 111, the third antenna element 113, and the second antenna element 112 may be the same or different. The spacing between two adjacent antenna elements 11 may be equal or different.
Referring to fig. 14, the third antenna unit 113 includes a third branch port 43. The third antenna unit 113 is electrically connected to one end of the conductive rotary shaft 33. Specifically, the third feeding port 43 is directly electrically connected to the conductive rotating shaft 33. Further, the third sub feed port 43 is electrically connected to the main feed port 30.
By setting the first antenna unit 111, the third antenna unit 113, and the second antenna unit 112 as the array antenna 1, the phases of the signals received by the first antenna unit 111, the third antenna unit 113, and the second antenna unit 112 can be distributed in an equal difference manner by adjusting the phase shift amounts of the first antenna unit 111 and the second antenna unit 112 to be the same and increasing or decreasing each other without adjusting the phase of the third antenna unit 113, thereby realizing beam scanning.
Specifically, the third branch feeder port 43 is located between the first branch feeder port 41 and the second branch feeder port 42, and is spaced apart from both the first branch feeder port 41 and the second branch feeder port 42. Further, the first branch feed port 41, the third branch feed port 43, and the second branch feed port 42 are collinear and arranged in the X-axis direction in sequence.
Referring to fig. 15, the phase compensation network 6 further includes a third phase compensation element 63. The third phase compensator 63 electrically connects the third feeding port 43 of the third antenna unit 113 and the conductive rotation shaft 33. The third phase compensator 63 is used for performing phase compensation on the signal radiated by the third antenna unit 113, so as to meet the requirement of the phase of the signal radiated by the third antenna unit 113.
Alternatively, the phase shift amount of the third phase compensator 63 may be adjustable or not, and reference may be made to the description of the second phase compensator 62 and the first phase compensator 61. The third phase compensator 63 may be a conductive via, a microstrip line, or the like. In this embodiment, the third phase compensator 63 is a microstrip line.
Referring to fig. 15, the first conductive slideway 32 is an axisymmetric structure. The first conductive runner 32 includes a first intermediate portion 323. The line connecting the first intermediate portion 323 to the conductive shaft 33 coincides with the axis of symmetry of the first conductive runner 32. Further, the conductive shaft 33 may be disposed at a center of a connecting line of the two opposite ends of the first conductive slideway 32. Of course, in other embodiments, the conductive shaft 33 may also be offset from the center position.
Further, the conductive rotation shaft 33 corresponds to the third antenna unit 113 in the Z-axis direction. One end of the first conductive runner 32 corresponds to the first antenna element 111 in the Z-axis direction. The other end of the first conductive runner 32 corresponds to the second antenna element 112 in the Z-axis direction.
Optionally, the conductive length of the first phase compensator 61 is equal to the conductive length of the second phase compensator 62. When the conductive sliding piece 34 is disposed in the first middle portion 323 of the first conductive sliding track 32, the lengths of the first sliding track portion 321 and the second sliding track portion 322 are equal, the length of the conductive path from the main feed port 30 to the first branch feed port 41 is the same as the length of the conductive path from the main feed port 30 to the second branch feed port 42, and the length of the conductive path from the main feed port 30 to the first branch feed port 41 is decreased (or increased) by N length and the length of the conductive path from the main feed port 30 to the second branch feed port 42 is also increased (or decreased) by N length by adjusting the rotation angle of the conductive sliding piece 34, so that the phase shift amount of the first antenna unit 111 and the second antenna unit 112 is the same and is increased or decreased, and the phase of the signals received by the first antenna unit 111, the third antenna unit 113 and the second antenna unit 112 is distributed in equal difference without adjusting the phase of the third antenna unit 113, thereby realizing beam scanning.
When conductive slide 34 slides to first intermediate portion 323, the sum of the conductive length of first phase compensator 61, the conductive length of conductive slide 34, and the conductive length of first conductive runner 32 connected between conductive slide 34 and first phase compensator 61 is equal to the conductive length of third phase compensator 63, i.e., the length of the conductive path between main feed port 30 to first shunt feed port 41 is the same as the length of the conductive path between main feed port 30 to third shunt feed port 43. Further, the length of the conductive path between the main feed port 30 and the second sub feed port 42 is also the same as the length of the conductive path between the main feed port 30 and the third sub feed port 43, so that the beam of the array antenna 1 is directed at the 0 ° position when the conductive slider 34 is in the first middle portion 323. The 0 position is the normal direction of the first face 102.
The conductive length of the third phase compensator 63 is greater than the conductive length of the first phase compensator 61 and the conductive length of the third phase compensator 63 is greater than the conductive length of the second phase compensator 62.
The excitation energy from the main feed port 30 is input to the branch feed ports of the antenna elements 11, which are the first branch feed port 41, the third branch feed port 43, and the second branch feed port 42 from left to right. The phase delay amount from the excitation energy main feed port 30 to the third branch feed port 43 is the smallest, and the phase delay amount from the first branch feed port 41 to the second branch feed port 42 is relatively large. By setting the conductive length of the third phase compensator 63 to be greater than the conductive length of the first phase compensator 61 and the conductive length of the third phase compensator 63 to be greater than the conductive length of the second phase compensator 62, it is possible to effectively compensate for the phase delay amount of the excitation energy received by the third feeding port 43, so that when the conductive sliding piece 34 slides to the first intermediate portion 323, the phases of the main feeding port 30 to the sub feeding ports of the respective antenna elements 11 are uniform, thereby directing the array antenna 1 to the 0 ° position.
Referring to fig. 15, a straight line segment, an arc segment, or a broken line segment is formed between the end of the first conductive sliding path 32 connected to the first phase compensation element 61 and the first middle portion 323 of the first conductive sliding path 32. Since the first conductive runner 32 has an axisymmetrical structure, a portion of the first conductive runner 32 between the end portion of the first phase compensator 61 and the first intermediate portion 323 and a portion of the first conductive runner 32 between the end portion of the second phase compensator 62 and the first intermediate portion 323 have the same shape, the opposite structure, and the same length.
In this embodiment, the portion of the first conductive sliding path 32 connecting the end of the first phase compensator 61 and the first middle portion 323 and the portion of the first conductive sliding path 32 connecting the end of the second phase compensator 62 and the first middle portion 323 are both 1/4 circular arcs, so the first conductive sliding path 32 is in a semi-circular arc shape. The conductive rotating shaft 33 may be located at the center of the semi-circular arc. Of course, in other embodiments, the first conductive runner 32 may also be a 120 ° arc segment, a 270 ° arc segment, or the like.
In other embodiments, referring to fig. 16, the first conductive runner 32 may also be two waists of an isosceles triangle, wherein the intersection point between the two waists is the first middle portion 323. In other embodiments, the first conductive runner 32 may also be the top side and two legs of an isosceles trapezoid, where the top side of the isosceles trapezoid is centered at the first middle portion 323.
By designing the first conductive runners 32 to be isosceles triangles or isosceles trapezoids, the area occupied by the first conductive runners 32 can be reduced compared to circular arcs, which facilitates miniaturization of the array antenna assembly 10.
