Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an adjustable antenna array and electronic device. Background Technology

[0002] In dual-polarized or multi-polarized antenna array design, multiple polarization modes can be implemented simultaneously in a single antenna element. Among them, dual-polarized antennas based on dual polarization modes have gradually become an indispensable component of wireless communication systems due to their advantages such as the ability to simultaneously transmit two orthogonal electromagnetic wave signals with minimal interference between them and ease of full-duplex operation, thus influencing the performance of the communication system.

[0003] In practical dual-polarization liquid crystal antenna unit and array design, the number of phase shifters corresponding to the antenna unit also increases exponentially due to the multiplication of polarization modes. This leads to insufficient space for device placement, significantly increasing the complexity of the design layout. Furthermore, the corresponding increase in control circuits and drive circuits also increases the complexity of the control system. These and other problems urgently need to be addressed.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0056] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains. As used in this disclosure, the words “comprising” or “including” and similar terms mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, but do not exclude other elements or objects.

[0057] In related technologies, Figure 1 The diagram shows one top-view schematic of a 2x2 antenna array composed of four antenna elements. The antenna element 01 has dimensions a*b, where a = 0.25λ and b = 0.25λ, and λ is the wavelength corresponding to the operating frequency of the center of the antenna array. The horizontal and vertical spacing of the antenna elements 01 is 0.5λ. Each antenna element 01 corresponds to a phase shifter 02, and the antenna element 01 and its corresponding phase shifter 02 are coupled via a feed line 03, allowing the phase shifter 02 to drive the antenna element 01 one-to-one. Each phase shifter 02 is also coupled to a control line 04 for drive control. Figure 2 As shown Figure 1 A corresponding cross-sectional structural diagram, where 05 represents the upper substrate, 06 represents the lower substrate, and 07 represents the ground plane. Figure 1As shown, in the actual layout, this 2*2 antenna array needs to arrange four phase shifters 02, four sets of feed lines 03, and four sets of control lines 04 within a λ*λ space, while considering the lateral and longitudinal spacing of the antenna elements 01. Especially when the size of a single phase shifter 02 is large, this poses a challenge to the design of the antenna elements 01 and the layout of the array. It is necessary to take into account the performance connection between the antenna elements 01 and the phase shifters 02, the performance impact between the feed lines 03 and the phase shifters 02, the routing of multiple control lines 04, and many other factors, which restricts the design. The difficulty will increase further as the array size increases.

[0058] In view of this, embodiments of the present disclosure provide an adjustable antenna array and electronic device for saving layout space.

[0059] Combination Figure 3 and Figure 4 As shown, this disclosure provides an adjustable antenna array. Wherein, Figure 3 This is a top-view schematic diagram of one possible structure of the adjustable antenna array. Figure 4 for Figure 3 A schematic diagram of one corresponding cross-sectional structure. Specifically, the adjustable antenna array includes:

[0060] The first base 10 and the second base 20 are set opposite to each other, and the multiple antenna subarrays 30 are arranged in an array.

[0061] Among them, at least a portion of the plurality of antenna subarrays 30 includes a phase shifter 40, a power divider feed network 50, and a plurality of radiating elements 60; the phase shifter 40 and the power divider feed network 50 are located between the first substrate 10 and the second substrate 20, at least a portion of the plurality of radiating elements 60 are connected to the phase shifter 40 through the power divider feed network 50, and the antenna pattern corresponding to the plurality of radiating elements 60 includes at least a portion of the pattern located on the side of the second substrate 20 opposite to the first substrate 10, and the orthogonal projection area of ​​the power divider feed network 50 on the first substrate 10 is smaller than the orthogonal projection area of ​​the phase shifter 40 on the first substrate 10.

[0062] In practical implementation, the adjustable antenna array includes a first substrate 10 and a second substrate 20 arranged opposite each other, and multiple antenna subarrays 30 arranged in an array. The first substrate 10 and the second substrate 20 can be glass substrates, polyimide (PI), liquid crystal polymer (LCP), printed circuit boards (PCBs), ceramics, etc. Of course, the first substrate 10 and the second substrate 20 can be configured according to actual application needs, and are not limited here. Furthermore, the specific number of antenna subarrays 30 can be set according to actual application needs, and is not limited here.

[0063] At least a portion of the multiple antenna subarrays 30 include phase shifters 40, power divider feed networks 50, and multiple radiating elements 60. The number of phase shifters 40 can be one or more. The number of power divider feed networks 50 can also be one or more. The specific number of phase shifters 40 and power divider feed networks 50 can be set according to the specific number of multiple radiating elements 60 in the actual antenna subarray 30, and is not limited here. Figure 3 The diagram illustrates an adjustable antenna array comprising two antenna subarrays 30 arranged in an array, wherein each antenna subarray 30 contains two radiating elements 60, a power divider feed network 50, and a phase shifter 40, but is not limited to this configuration. The phase shifter 40 and the power divider feed network 50 are located between the first substrate 10 and the second substrate 20, and at least some of the radiating elements 60 are connected to the phase shifter 40 via the power divider feed network 50. Since the power divider feed network 50 can split the signal input to the phase shifter 40 into multiple paths and provide them to the corresponding radiating elements 60, even if the number of radiating elements 60 is large and fixed, the number of phase shifters 40 can be reduced to some extent. Furthermore, the projected area of ​​the power divider feed network 50 on the first substrate 10 is smaller than the projected area of ​​the phase shifter 40 on the first substrate 10. That is, although the adjustable antenna array includes a power divider feed network 50, the power divider feed network 50 can be designed to be much smaller than a single phase shifter 40. In this way, while reducing the number of phase shifters 40, the layout space of the adjustable antenna array is effectively saved.

[0064] It should be noted that the power divider feed network 50 is essentially a portion of the feed lines in the adjustable antenna array, excluding the phase shifter 40 and the power divider feed network 50. Correspondingly, the orthographic projection area of ​​the power divider feed network 50 on the first substrate 10 is essentially the area of ​​the cross-sectional shape of this portion of the feed line parallel to the plane containing the first substrate 10. Specifically, the width of the cross-sectional shape of this portion of the feed line is much smaller than the width of the cross-sectional shapes of the phase shifter 40 and the power divider feed network 50 parallel to the plane containing the first substrate 10, and the orthographic projection area of ​​the cross-sectional shape of this portion of the feed line on the first substrate 10 is much smaller than the orthographic projection area of ​​the phase shifter 40 on the first substrate 10.

[0065] In addition, it should be noted that Figure 4 The figures simply illustrate the positional relationships between the components in the adjustable antenna array. The dimensions and shapes of the figures mentioned in the embodiments of this disclosure do not reflect actual scale and are intended only to illustrate the content of this disclosure. Furthermore, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0066] In one exemplary embodiment, at least a portion of the radiating element 60 and the output port of the power divider feed network 50 connected to at least a portion of the radiating element 60 have orthographic projections onto the first substrate 10 that at least partially overlap. In one exemplary embodiment, as... Figure 5 As shown, the output port of the power divider network 50 can be directly electrically connected to at least a portion of the radiating elements 60 via a through-glass via (TGV) (H) through the corresponding substrate. In one exemplary embodiment, the output port of the power divider network 50 can be coupled to at least a portion of the radiating elements 60. Of course, the connection method between the power divider network 50 and at least a portion of the radiating elements 60 can be configured according to actual application needs, and is not limited here.

[0067] In a specific implementation, the antenna pattern corresponding to the plurality of radiating elements 60 includes at least a portion of the pattern located on the side of the second substrate 20 opposite to the first substrate 10. In one exemplary embodiment, as shown... Figure 3 As shown, the antenna patterns corresponding to the plurality of radiating elements 60 include a portion of the pattern located on the side of the second substrate 20 opposite to the first substrate 10. In one exemplary embodiment, the antenna patterns corresponding to the plurality of radiating elements 60 include not only a portion of the pattern located on the side of the second substrate 20 opposite to the first substrate 10, but also a portion of the pattern located on the side of the first substrate 10 opposite to the second substrate 20, thereby improving the radiation range of the corresponding antenna subarray 30.

[0068] It should be noted that the positional relationship of each element within the antenna subarray 30 in the adjustable antenna array can be as shown in the following cases.

[0069] In practical implementation, when the antenna subarray 30 includes Q radiating elements 60, the number of phase shifters 40 within the antenna subarray 30 and the number of control lines 400 connected to the phase shifters 40 can both be reduced to 1 / Q of the original number, where Q is a positive integer greater than 1. The following explanation uses an example where each radiating element 60 has dimensions a*b, a = 0.25λ, b = 0.25λ, where λ is the wavelength corresponding to the center operating frequency of the adjustable antenna array, and the lateral and longitudinal spacing between adjacent radiating elements 60 is 0.5λ. This example illustrates the positional relationship of the elements within the antenna subarray 30 and its applicable application scenarios.

[0070] For example, antenna subarray 30 includes m longitudinally arranged radiating elements 60, where m is a positive integer greater than 1. In this case, the longitudinal spacing between adjacent antenna subarrays 30 can be m*0.5*λ. If the feed signals of each radiating element 60 are consistent, the longitudinal scanning angle of the adjustable antenna array will be relatively... Figure 1 The size of a single radiating element 60 within a subarray is reduced, and consequently, this adjustable antenna array can be applied to electronic devices with low requirements for longitudinal scanning performance.

[0071] For example, antenna subarray 30 includes n horizontally arranged radiating elements 60, where n is a positive integer greater than 1. In this case, the horizontal spacing between adjacent antenna subarrays 30 can be n*0.5*λ. If the feed signals of each radiating element 60 are consistent, the horizontal scanning angle of the adjustable antenna array will be relatively large compared to... Figure 1 The size of a single radiating element 60 within a subarray is reduced, and consequently, this adjustable antenna array can be applied to electronic devices with lower requirements for lateral scanning performance.

[0072] For example, if the Q radiating elements 60 in the antenna subarray 30 are not arranged in an m*n rectangular pattern, and the feed signals of each radiating element 60 are kept consistent, then the feed signals of the elements in different subarrays can produce specific performance differences, which can ensure the specific product performance corresponding to the adjustable antenna array.

[0073] For example, the total power distribution feed network 50 corresponding to the Q radiating elements 60 in the antenna subarray 30 can be composed of a 1-to-Q power distribution feed network plus a feed line 600. The 1-to-Q power distribution feed network can be continuously connected by several 1-to-2 power distribution feed networks. Moreover, according to the impedance matching design requirements of the corresponding power distribution feed network 50, the line width and line length of the 1-to-2 power distribution feed networks at asymmetrical positions can be different.

[0074] In this embodiment, the arrangement and driving method of the antenna subarrays 30 in the adjustable antenna array can take various forms, mainly reflected in the number of radiating elements 60 connected within the antenna subarray 30, the connection relationship between the elements within the antenna subarray 30, and their positional relationship. In one exemplary embodiment, the input port 501 of the power divider feed network 50 is connected to the phase shifter 40, and the multiple output ports 502 of the power divider feed network 50 are respectively configured to correspond one-to-one with the corresponding radiating elements 60.

[0075] In specific implementation, the input port 501 of the power divider feeder network 50 and the phase shifter 40 can be connected electrically or coupled, without limitation. In one exemplary embodiment, the multiple output ports 502 of the power divider feeder network 50 can be respectively configured to correspond one-to-one with the corresponding radiating elements 60, and the number of multiple output ports 502 is equal to the number of multiple radiating elements 60.

[0076] In one exemplary embodiment, such as Figure 6 The diagram shows a top-view schematic of one type of antenna subarray 30 in an adjustable antenna array. It includes two radiating elements 60, one power divider feed network 50, two output ports 502 of the power divider feed network 50, and one phase shifter 40. Since the power divider feed network 50 includes two output ports 502, which are connected to the two radiating elements 60 respectively, the signal input to the input port 501 of the power divider feed network 50 via the phase shifter 40 is output as two separate signals via its two output ports 502. These two signals can be provided to the corresponding radiating elements 60. Furthermore, the number of output ports 502 can be set according to the specific number of radiating elements 60 in the actual application. For example, three radiating elements 60 can be connected to the three output ports 502 of the power divider feed network 50. Or, four radiating elements 60 can be connected to the four output ports 502 of the power divider feed network 50. The following example illustrates this. Figure 3 Taking the example shown, the situation where multiple output ports 502 of the power distribution feeder network 50 are respectively set to correspond one-to-one with the corresponding radiation units 60 will be explained. Figure 3 The adjustable antenna array shown is essentially a 2x2 array consisting of four radiating elements 60. Only two phase shifters 40 are needed in this array. Figure 1 In comparison, when the size of a single antenna element and a single radiating element 60 are the same, and the size of a single phase shifter 40 is the same, the number of phase shifters 40 is reduced by half, and the number of control lines 400 connected to the phase shifters 40 is also reduced by half, thus saving layout space.

[0077] In one exemplary embodiment, combined with Figures 7 to 9As shown, there are at least three of the plurality of radiating units 60, at least two of the power distribution feed networks 50, and the number of output ports 502 of each of the power distribution feed networks 50 is less than the number of the plurality of radiating units 60.

[0078] In specific implementation, the number of multiple radiating elements 60 can be three or more, depending on the actual application requirements; no limitation is imposed here. There are at least two power divider feed networks 50, and the number of power divider feed networks 50 can be two or more, depending on the actual application requirements; no limitation is imposed here. The number of output ports 502 of each power divider feed network 50 is less than the number of multiple radiating elements 60. In one exemplary embodiment, each power divider feed network 50 has two output ports 502, and the multiple radiating elements 60 have three. In one exemplary embodiment, some power divider feed networks 500 have two output ports 502, some have three, and the radiating elements 60 have five. Of course, the number of output ports 502 of each power divider feed network 50 can be set according to the performance requirements of the adjustable antenna array; no limitation is imposed here.

[0079] In this embodiment of the disclosure, combined with Figures 3 to 10 As shown, the line length and line width of each output port 502 in the power divider network 50 are equal. This ensures that the physical structure of the power divider network 50 and the electrical performance of each output port 502 are consistent, achieving equivalent driving of the corresponding radiating unit 60 by each output port 502.

[0080] In this embodiment of the disclosure, combined with Figures 3 to 10 As shown, each of the power distribution feeder networks 50 has the same number of output ports 502. For example, each power distribution feeder network 50 has two output ports 502. Alternatively, each power distribution feeder network 50 has three output ports 502. The specific number of output ports 502 for each power distribution feeder network 50 can be set according to actual application needs and is not limited here.

[0081] In this embodiment of the disclosure, combined with Figures 3 to 10 As shown, the power distribution feed network 50 includes a first-stage power distribution feed network 70 and a second-stage power distribution feed network 80. The output port 502 of the first-stage power distribution feed network 70 is connected to the plurality of radiating units 60. The input port 501 of the first-stage power distribution feed network 70 is connected to the output port 502 of the second-stage power distribution feed network 80. The input port 501 of the second-stage power distribution feed network 80 is connected to the phase shifter 40.

[0082] In specific implementation, the power distribution feeder network 50 may include a first-stage power distribution feeder network 70 and a second-stage power distribution feeder network 80. The first-stage power distribution feeder network 70 can be one or more. The second-stage power distribution feeder network 80 can also be one or more. The specific number of the first-stage power distribution feeder network 70 and the second-stage power distribution feeder network 80 can be set according to actual application needs and is not limited here. Furthermore, the output port 502 of the first-stage power distribution feeder network 70 is connected to multiple radiating units 60, the input port 501 of the first-stage power distribution feeder network 70 is connected to the output port 502 of the second-stage power distribution feeder network 80, and the input port 501 of the second-stage power distribution feeder network 80 is connected to the phase shifter 40. In one exemplary embodiment, the power distribution feeder networks at each stage can be connected electrically or coupled. Furthermore, the corresponding power distribution feeder network and the phase shifter 40 can be connected electrically or coupled, and is not limited here. In this way, the signal input to the input port 501 of the second-stage power divider network 80 via the phase shifter 40 is first output from the output port 502 of the second-stage power divider network 80, and then each signal is input to the input port 501 of the first-stage power divider network 70. Then, each signal is output to the corresponding radiating element 60 via the output ports 502 of the first-stage power divider network 70, thereby ensuring the driving of multiple radiating elements 60 and ensuring the performance of the adjustable antenna array.

[0083] In one exemplary embodiment, combined with Figures 3 to 10 As shown, both the first-stage power distribution feeder network 70 and the second-stage power distribution feeder network 80 have two output ports 502. Correspondingly, both the first-stage power distribution feeder network 70 and the second-stage power distribution feeder network 80 are one-drive-two-power-distribution feeder networks.

[0084] Combination Figures 7 to 9 As shown, there is an even number of the plurality of radiating units 60, and every two radiating units 60 are connected to the output port 502 of a first-stage power distribution network 70.

[0085] Combination Figure 7 and Figure 8As shown, there are four radiating units 60, two first-stage power divider feed networks 70, and one second-stage power divider feed network 80. Each pair of adjacent radiating units 60 is connected to the output port 502 of one first-stage power divider feed network 70, and each pair of adjacent radiating units 60 is connected to the output port 502 of another first-stage power divider feed network 70. The input ports 501 of the two first-stage power divider feed networks 70 are connected to the output ports 502 of the second-stage power divider feed network 80.

[0086] Still combined Figure 7 As shown, the subarray comprises four radiating elements 60, two first-stage power divider feed networks 70, one second-stage power divider feed network 80, and a phase shifter 40. The four radiating elements 60 are arranged laterally in the same direction. Two adjacent radiating elements 60 are connected to the output port 502 of one first-stage power divider feed network 70, and another two adjacent radiating elements 60 are connected to the output port 502 of the other first-stage power divider feed network 70. In practice, the line length and linewidth of each output port 502 in each first-stage power divider feed network 70 are equal, ensuring the consistency of the electrical performance of each output port 502 and improving the performance of the adjustable antenna array. Furthermore, the input ports 501 of the two first-stage power divider feed networks 70 are connected to the output ports 502 of the second-stage power divider feed network 80. In one exemplary embodiment, the input ports 501 of the two first-stage power divider feed networks 70 and the output ports 502 of the second-stage power divider feed network 80 can be electrically connected respectively; in another exemplary embodiment, the input ports 501 of the two first-stage power divider feed networks 70 and the output ports 502 of the second-stage power divider feed network 80 can be coupled respectively. The line length and linewidth of each output port 502 in each second-stage power divider feed network 80 are equal, thereby ensuring the consistency of the electrical performance of each output port 502 and improving the performance of the adjustable antenna array.

[0087] Still combined Figure 8 As shown, the subarray comprises four radiating elements 60, two first-stage power divider feed networks 70, one second-stage power divider feed network 80, and a phase shifter 40. The four radiating elements 60 are arranged in a 2x2 array. Combined with... Figure 9As shown, there are four radiating units 60, one first-stage power divider feed network 70, and one second-stage power divider feed network 80. Two adjacent radiating units 60 are connected to the output port 502 of the first-stage power divider feed network 70, and one of the remaining two radiating units 60 is connected to the output port 502 of the second-stage power divider feed network 80. The other of the remaining two radiating units 60 is directly connected to another phase shifter 40.

[0088] Still combined Figure 9 As shown, the subarray comprises four radiating elements 60, a first-stage power divider feed network 70, a second-stage power divider feed network 80, and two phase shifters 40. The four radiating elements 60 are arranged in a 2x2 array. Each adjacent radiating element 60 is connected to the output port 502 of the first-stage power divider feed network 70. The input port 501 of the first-stage power divider feed network 70 is connected to one of the remaining two radiating elements 60 and to the output port 502 of the second-stage power divider feed network 80. In one exemplary embodiment, the input port 501 of the first-stage power divider feed network 70 can be electrically connected to one of the output ports of the second-stage power divider feed network, and one of the remaining two radiating elements 60 is coupled to the output port 502 of the second-stage power divider feed network 80. In this way, the signal input to the input port 501 of the second-stage power divider feed network 80 via the phase shifter 40 is input to the input port 501 of the first-stage power divider feed network 70 and the corresponding radiating element 60 via the two output ports 502 of the second-stage power divider feed network 80, respectively. Then, the signal input to the input port 501 of the first-stage power divider feed network 70 is input to the corresponding radiating element 60 via the two output ports 502 of the first-stage power divider feed network 70. The radiating element 60, which is directly coupled to the other phase shifter 40, can directly receive the signal from the other phase shifter. In this way, while saving layout space, the flexible design of the subarray structure is ensured, and the performance of the adjustable phased array is improved.

[0089] In this embodiment of the disclosure, combined with Figure 10 As shown, the plurality of radiating units 60 is an odd number, and every two radiating units 60 are connected to the output port 502 of the first-stage power divider feed network 70, and the remaining radiating unit 60 is connected to the output port 502 of the second-stage power divider feed network 80.

[0090] Still combined Figure 10As shown, there are three radiating units 60, one first-stage power divider feed network 70, and one second-stage power divider feed network 80. Two adjacent radiating units 60 are connected to the output port 502 of the first-stage power divider feed network 70, and the input port 501 of the first-stage power divider feed network 70 and the remaining radiating unit 60 are connected to the output port 502 of the second-stage power divider feed network 80.

[0091] Still combined Figure 10 As shown, the subarray includes three radiating elements 60, a first-stage power divider feed network 70, a second-stage power divider feed network 80, and a phase shifter 40. The three radiating elements 60 are arranged laterally in the same direction. Adjacent radiating elements 60 are connected to the output port 502 of the first-stage power divider feed network 70, and the input port 501 of the first-stage power divider feed network 70 and the remaining radiating element 60 are connected to the output port 502 of the second-stage power divider feed network 80. In one exemplary embodiment, the input port 501 of the first-stage power divider feed network 70 is electrically connected to one of the output ports 502 of the second-stage power divider feed network 80, and the remaining radiating element 60 is coupled to the output port 502 of the second-stage power divider feed network 80. Furthermore, the input port 501 of the second-stage power divider feed network 80 is coupled to the phase shifter 40. In this way, the signal input from the phase shifter 40 to the input port 501 of the second-stage power divider feed network 80 is input to the corresponding radiating element 60 and the input port 501 of the first-stage power divider feed network 70 via the two output ports 502 of the second-stage power divider feed network 80, respectively; then, it is input to the two corresponding radiating elements 60 via the two output ports 502 of the first-stage power divider feed network 70. This saves layout space while ensuring the performance of the adjustable antenna array.

[0092] It should be noted that, within the same antenna subarray 30, the thickness of the control line 400 coupled to the phase shifter 40 can be less than the thickness of the corresponding metal film layers of the phase shifter 40, the power divider feed network 50, and the feed line 600. The number of control lines 400 depends on the number of phase shifters 40, and typically the number of control lines 400 is consistent with the number of phase shifters 40. Drive signals can be provided to the corresponding phase shifters 40 through the control lines 400, thereby adjusting the phase shift degree of the phase shifter 40. The material of the control line 400 can be indium tin oxide (ITO), ensuring the driving capability of the phase shifter while maintaining the light transmittance of the antenna subarray 30.

[0093] Furthermore, after the arrangement and driving configuration of the antenna subarrays 30 are determined, multiple antenna subarrays 30 can be arranged to form the desired array. For the same antenna subarray 30, M subarrays can be extended horizontally and N subarrays can be extended vertically. Each antenna subarray 30 includes Q radiating elements 60, thus forming a large array consisting of M*N antenna subarrays 30 and containing M*N*Q radiating elements 60. In addition, several different antenna subarrays 30 can be freely combined to form various large arrays according to actual application needs.

[0094] In one exemplary embodiment, the plurality of radiating elements 60 are arranged side by side. For example... Figure 11 The diagram shown is a top view of one possible array configuration. In this embodiment, the array includes 3*3 antenna subarrays 30 arranged in an array. Each antenna subarray 30 includes two radiating elements 60 arranged side by side, and the array includes a total of 3*3*2 radiating elements 60.

[0095] In one exemplary embodiment, the plurality of radiating elements 60 are arranged in an array. For example... Figure 12 The diagram shown is a top view of one of the array arrangements. In this embodiment, the array includes 3*3 antenna subarrays 30 arranged in an array, and each antenna subarray 30 includes four radiating elements 60 arranged in an array.

[0096] Of course, besides the array arrangement mentioned above, the various subarrays in the array and the various radiating elements 60 in the antenna subarray 30 can also be arranged according to actual application needs, which will not be detailed here. In the embodiments of this disclosure, the radiating elements 60 constituting the antenna subarray 30 and the array can have various polarization forms. In one exemplary embodiment, combined with Figures 13 to 18 As shown, each of the radiating elements 60 is a single-polarization structure with the same polarization direction. The single-polarization structure includes any one of vertical polarization, horizontal polarization, +45° polarization, -45° polarization, right-hand circular polarization, and left-hand circular polarization. Taking one antenna subarray 30 as an example, as... Figure 13 The diagram shown illustrates one type of structure in which both radiating elements 60 in a subarray are vertically polarized; as shown... Figure 14 The diagram shown illustrates one type of structure where both radiating elements 60 in the subarray are horizontally polarized; as shown... Figure 15 The diagram shown illustrates one possible structure where both radiating elements 60 in the subarray are polarized at +45°; Figure 16 The diagram shown illustrates one possible structure where both radiating elements 60 in the subarray are polarized at -45°. Figure 17 The diagram shown illustrates one type of structure where both radiating elements 60 in the subarray are right-handed circularly polarized; as shown... Figure 18The diagram shows one possible structure where both radiating elements 60 in the subarray are left-handed circularly polarized. The arrows in the diagram indicate the polarization direction of the corresponding radiating element 60.

[0097] In one exemplary embodiment, taking an antenna subarray 30 as an example, combined with Figures 19 to 21 As shown, each of the radiating units 60 is a dual-polarization structure comprising two different polarization directions. The dual-polarization structure includes any one of vertical and horizontal dual polarization, ±45° dual polarization, or left-right circular polarization. For example, Figure 19 The diagram shows one type of structure in which both radiating elements 60 in the subarray are vertically and horizontally dual-polarized; as shown... Figure 20 The diagram shown illustrates one possible structure where both radiating elements 60 in the subarray are ±45° dual-polarized; Figure 21 The diagram shown is a schematic of one type of structure in which both radiating elements 60 in the subarray are both left and right double circularly polarized.

[0098] In a specific implementation, each radiating element 60 in the adjustable antenna array is a dual-polarized structure with two different polarization directions. In one exemplary embodiment, the plurality of radiating elements 60 includes a first radiating element 601 and a second radiating element 602; the power divider feed network 50 includes a first power divider feed network 90 and a second power divider feed network 100; the phase shifter 40 includes a first phase shifter 110 and a second phase shifter 120; the output port 502 of the first power divider feed network 90 is connected to the first radiating element 601 and the second radiating element 602 respectively, and the input port 501 of the first power divider feed network 90 is connected to the first phase shifter 110 through a first feed line 130; the output port 502 of the second power divider feed network 100 is connected to the first radiating element 601 and the second radiating element 602 respectively, and the input port 501 of the second power divider feed network 100 is connected to the second phase shifter 120 through a second feed line 140.

[0099] In one exemplary embodiment, the input port 501 of the first power distribution feeder network 90 is electrically connected to the first phase shifter 110 via a first feeder 130, and the input port 501 of the second power distribution feeder network 100 is electrically connected to the second phase shifter 120 via a second feeder 140. In another exemplary embodiment, the input port 501 of the first power distribution feeder network 90 is coupled to the first phase shifter 110 via a first feeder 130, and the input port 501 of the second power distribution feeder network 100 is coupled to the second phase shifter 120 via a second feeder 140. In yet another exemplary embodiment, the input port 501 of the first power distribution feeder network 90 is coupled to the first phase shifter 110 via a first feeder 130, and the input port 501 of the second power distribution feeder network 100 is electrically connected to the second phase shifter 120 via a second feeder 140. Of course, the connection method between the power distribution network and the corresponding phase shifter can be set according to the actual application needs, and no limitation is made here.

[0100] Still combined Figures 19 to 21 As shown, the antenna subarray 30 in the adjustable antenna array is provided with two radiating elements, including a first radiating element 601 and a second radiating element 602; two power-dividing feed networks, including a first power-dividing feed network 90 and a second power-dividing feed network 100; and two phase shifters, including a first phase shifter 110 and a second phase shifter 120. The coupling relationship between the elements in this subarray can be as follows: the output port 502 of the first power-dividing feed network 90 is coupled to the first radiating element 601 and the second radiating element 602 respectively, and the input port 501 of the first power-dividing feed network 90 can be connected to the first phase shifter 110 through the first feed line 130; the output port 502 of the second power-dividing feed network 100 can be coupled to the first radiating element 601 and the second radiating element 602 respectively, and the input port 501 of the second power-dividing feed network 100 is connected to the second phase shifter 120 through the second feed line 140. In this way, even if the subarray is composed of a dual-polarization structure, the entire subarray only requires two power distribution feed networks and two phase shifters, thus saving layout space.

[0101] Still with Figures 19 to 21 Taking the illustrated embodiment as an example, the first phase shifter 110, the first feed line 130, the first power divider feed network 90, the second phase shifter 120, the second feed line 140, and the second power divider feed network 100 are all fabricated from a single layer of metal film with the same thickness on the same substrate. The metal film can be made of materials such as copper (Cu), silver (Ag), or aluminum (Al). This reduces the manufacturing cost of the subarray and improves the manufacturing efficiency of the tunable antenna array. Figure 22 As shown Figures 19 to 21 A schematic diagram of one type of cross-sectional structure corresponding to any one of the structures in the diagram, such as... Figure 23 As shown Figures 19 to 21 A schematic diagram of one cross-sectional structure corresponding to any one of the structures. In one exemplary embodiment, combined with Figure 22 As shown, the units coupled to the first radiating unit 601 and the units coupled to the second radiating unit 602 are arranged symmetrically in structure. Accordingly, the first phase shifter 110 and the second phase shifter 120 have the same structural parameters, including linewidth and line length; the first feed line 130 and the second feed line 140 have the same structural parameters, including linewidth and line length, on the same substrate; the first power divider feed network 90 and the second power divider feed network 100 have the same structural parameters, including linewidth and line length, on the same substrate.

[0102] In one exemplary embodiment, combined with Figure 23 As shown, the units coupled to the first radiating unit 601 and the units coupled to the second radiating unit 602 are structurally asymmetrically arranged. Correspondingly, the structural parameters of units with the same performance for each radiating unit can be different. For example, the first feed line 130 and the second feed line 140, which are on the same substrate, have different structural parameters, including linewidth and line length. Figure 23 As shown, the linewidth of the first feed line 130 is smaller than the linewidth of the second feed line 140.

[0103] In one exemplary embodiment, such as Figure 24 As shown, the adjustable antenna array provided in this embodiment can be a reflective antenna array. Specifically, the adjustable antenna array further includes a ground electrode 150 located on the side of the first substrate 10 away from the second substrate 20, and the orthographic projection of each of the radiating elements on the first substrate 10 completely falls within the area of ​​the orthographic projection of the ground electrode 150 on the first substrate 10, so that the electromagnetic wave signal received by the adjustable antenna array on the side of the second substrate 20 away from the first substrate 10 is reflected from the same side via the ground electrode 150. Still in conjunction with... Figure 24 As shown, the electromagnetic wave signal received by the adjustable antenna array from the side of the second substrate 20 away from the first substrate 10 will be reflected back from the same side due to the grounding electrode 150 located on the side of the first substrate 10 away from the second substrate 20. The arrows indicate the direction of electromagnetic wave signal propagation. In this way, the propagation direction of the electromagnetic wave signal can be adjusted according to the actual application needs, thereby improving the performance of the adjustable antenna array.

[0104] In one exemplary embodiment, the adjustable antenna array provided in this disclosure can be a transmissive antenna array. Specifically, the antenna pattern further includes another portion of the pattern located on the side of the first substrate 10 opposite to the second substrate 20. The orthographic projections of this other portion of the pattern and the first portion of the pattern on the first substrate 10 at least partially overlap, so that electromagnetic wave signals received by the adjustable antenna array on the side of the second substrate 20 opposite to the first substrate 10 are transmitted out from the side of the first substrate 10 opposite to the second substrate 20. In a specific implementation, the antenna pattern further includes another portion of the pattern located on the side of the first substrate 10 opposite to the second substrate 20. The orthographic projections of this other portion of the pattern and the first portion of the pattern located on the side of the second substrate 20 opposite to the first substrate 10 at least partially overlap on the first substrate 10. Figure 25 The diagram shows a cross-sectional view of one embodiment of the adjustable antenna array provided in this disclosure. The diagram illustrates the complete overlap between one part of the antenna pattern and another part of the pattern, and the arrows in the diagram indicate the propagation direction of the electromagnetic wave signal. In this way, the electromagnetic wave signal received by the adjustable antenna array on the side of the second substrate 20 away from the first substrate 10 can be transmitted through the side of the first substrate 10 away from the second substrate 20, thereby ensuring the transmission performance of the adjustable antenna array.

[0105] Of course, in addition to the aforementioned reflective and transmissive antenna arrays, the adjustable antenna array can also be an adjustable phased array antenna array. Of course, other methods can be selected to set up the adjustable antenna array according to the actual application needs, which are not limited here.

[0106] It should be noted that the phase shifter in the tunable antenna array includes multiple non-overlapping phase shifting units on the same substrate. Each phase shifting unit includes a first electrode disposed on the side of the first substrate 10 facing the second substrate 20, a second electrode disposed on the side of the second substrate 20 facing the first substrate 10, and an intermediate dielectric layer 160 located between the first and second electrodes. The materials of the first and second electrodes can be the same or different. For example, the material of the first electrode can be indium tin oxide (ITO), copper (Cu), or silver (Ag), and the material of the second electrode can be indium tin oxide (ITO), copper (Cu), or silver (Ag), etc. Different materials have different conductivity and losses. In practical applications, the materials of the first and second electrodes can be selected according to the actual requirements of the phase shift degree of the phase shifter 40, and are not limited here. In one exemplary embodiment, the intermediate dielectric layer 160 can be a liquid crystal layer, and the corresponding phase shifter 40 is a liquid crystal phase shifter. The liquid crystal molecules of the liquid crystal layer can be positive liquid crystal molecules or negative liquid crystal molecules, and are not limited here. In addition, an insulating layer 170 is provided on both the side of the intermediate dielectric layer 160 closest to the first substrate 10 and the side closest to the second substrate 20. The insulating layer 170 can be SiN or SiO, which is not limited here. This effectively prevents external water and oxygen from corroding the relevant film layers in the tunable antenna array and improves the performance of the tunable antenna array.

[0107] Furthermore, when the intermediate dielectric layer 160 in the phase shifter 40 is a liquid crystal layer, an alignment layer can be pre-set to tilt the liquid crystal molecules in the liquid crystal layer at a preset angle. This improves the adjustment efficiency of the dielectric constant of the liquid crystal layer after the driving electrode is applied to the relevant electrode via the control line 400, thereby increasing the phase shifting efficiency. Of course, other films in the adjustable antenna array can also be set according to actual application needs; specific implementation details can be found in related technologies and will not be elaborated here.
