Description

Antenna devices and electronic equipment Technical Field

[0002] With the continuous advancement of mobile communication technology, the evolution from 2G to 5G has brought significant improvements in network performance, but it has also been accompanied by increased equipment complexity and space requirements. In particular, the deployment of 5G base stations, coexisting with 2G / 3G / 4G equipment on existing sites, has led to extremely limited rooftop space. Consequently, multi-band, multi-array, common-aperture antennas have become the mainstream for base station antennas. However, in a limited space, the dense placement of multiple array antennas inevitably causes severe mutual coupling, resulting in a significant deterioration in antenna performance. Therefore, how to improve antenna performance through reasonable decoupling design in multi-array, common-aperture antennas has become a pressing technical problem that needs to be solved.

[0086] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0087] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0088] This disclosure provides an antenna device comprising two elements operating at different frequency bands: a first element and a second element. The first element operates at a higher frequency than the second element. For example, the first element operates at a high frequency of 2.6 GHz, while the second element operates at a low frequency of 700 MHz. Both the first and second elements are integrated transceivers with a common aperture design. For ease of description, the first element is referred to as the high-frequency element, and the second element as the low-frequency element.

[0089] Figure 1 is a schematic diagram of an exemplary antenna unit 100 according to an embodiment of the present disclosure; Figure 2 is a schematic diagram of an exemplary antenna device according to an embodiment of the present disclosure; As shown in Figures 1 and 2, the antenna device includes a reflector 1 and a plurality of antenna units 100 disposed on the reflector 1 and arranged side by side. Each antenna unit 100 includes 5 elements, namely 4 high-frequency elements 101 and 1 low-frequency element 102; wherein the 4 high-frequency elements 101 are arranged in an array and are arranged around the low-frequency element 102, that is, the low-frequency element 102 is located in the middle of the 4 high-frequency elements 101.

[0090] Furthermore, since the high-frequency vibrator 101 and the low-frequency vibrator 102 operate in different frequency bands, their heights are different to prevent them from blocking each other. Specifically, for each antenna element 100, the height of the low-frequency vibrator 102 in the direction away from the reflector 1 is greater than the height of the high-frequency vibrator 101 in the same direction.

[0091] The antenna device includes not only the aforementioned structure but also a feeding structure to feed the vibrator within the antenna device. Taking a dual-polarized vibrator as an example, the coaxial cable includes a first coaxial cable and a second coaxial cable.

[0092] In some examples, Figure 3 is an exploded view of a high-frequency vibrator 101 according to an embodiment of the present disclosure; Figure 4 is a front view of the high-frequency vibrator 101 fixed to the reflector 1 according to an embodiment of the present disclosure; as shown in Figures 3 and 4, the high-frequency vibrator 101 includes a first balun assembly 21 and a second balun assembly 22 arranged in a cross configuration, and a radiating layer 23. The radiating layer 23 includes four radiating sections, namely a first radiating section 232a, a second radiating section 232b, a third radiating section 232c, and a fourth radiating section 232d. A first coaxial cable feeds the first radiating section 232a and the second radiating section 232b through the first balun assembly 21, and a second coaxial cable feeds the third radiating section 232c and the fourth radiating section 232d through the second balun assembly 22.

[0093] Specifically, the first balun assembly 21 of this embodiment includes a first fixing plate 211, a first balun feed line 212 disposed on the first fixing plate 211, and a first reference electrode 213 disposed on the side of the first fixing plate 211 opposite to the first balun feed line 212. The second balun assembly 22 includes a second fixing plate 221, a second balun feed line 222 disposed on the second fixing plate 221, and a second reference electrode 223 disposed on the side of the second fixing plate 221 opposite to the second balun feed line 222. The first fixing plate 211 and the second fixing plate 221 are intersecting, and the planes of both the first fixing plate 211 and the second fixing plate 221 form an angle with the plane of the first substrate 1. For example, the first fixing plate 211 and the second fixing plate 221 are orthogonal, and the plane of the first fixing plate 211 is perpendicular to the plane of the reflector 1, and the plane of the second fixing plate 221 is perpendicular to the plane of the reflector 1.

[0094] The first coaxial cable is connected to the first balun feed line 212 of the first balun assembly 21, and the second coaxial cable is correspondingly connected to the second balun feed line 222 of the second balun assembly 22. The first reference electrode 213 of the first balun assembly 21 is connected to the first radiating section 232a and the second radiating section 232b; the second reference electrode 223 of the second balun assembly 22 is connected to the third radiating section 232c and the fourth radiating section 232d. In this configuration, the first coaxial cable powers the first balun feed line 212, and the second coaxial cable powers the second balun feed line 222. Signal radiation is then generated in the radiating layer 23 through the first balun feed line 212 and the second balun feed line 222. This structure effectively improves radiation efficiency, resulting in a high gain for the antenna.

[0095] Furthermore, the planes containing the first fixing plate 211 and the second fixing plate 221 have a certain included angle, for example, the included angle is 90°, meaning the first fixing plate 211 and the second fixing plate 221 are orthogonally arranged. The planes containing the first fixing plate 211 and the second fixing plate 221 also have a certain included angle relative to the plane containing the reflector 1, for example, the plane containing the first fixing plate 211 is perpendicular to the plane containing the reflector 1, and correspondingly, the plane containing the second fixing plate 221 is also perpendicular to the plane containing the reflector 1. In this embodiment, only the example of the first fixing plate 211 and the second fixing plate 221 being orthogonally arranged, and both their planes being perpendicular to the plane containing the reflector 1, is used.

[0096] Figure 5 is a cross-sectional view of the first balun assembly according to an embodiment of the present disclosure; Figure 6 is a top view of one side of the first balun assembly according to an embodiment of the present disclosure; Figure 7 is a top view of the other side of the first balun assembly according to an embodiment of the present disclosure; Figure 8 is a cross-sectional view of the second balun assembly according to an embodiment of the present disclosure; Figure 9 is a top view of one side of the second balun assembly according to an embodiment of the present disclosure; Figure 10 is a top view of the other side of the second balun assembly according to an embodiment of the present disclosure; Referring to Figures 5-10, the first fixing plate 211 has a first opening extending along the thickness direction of the reflector plate 1, and the second fixing plate 221 has a second opening extending along the thickness direction of the reflector plate 1. The first fixing plate 211 is fixed to the second fixing plate 221 through the first opening, and the second fixing plate 221 is fixed to the first fixing plate 211 through the second opening, so that the two are orthogonally arranged. Since the first fixing plate 211 and the second fixing plate 221 are orthogonal, the second fixing plate 221 divides the first fixing plate 211 into a first sub-plate 2111 and a second sub-plate 2112, and the first fixing plate 211 divides the second fixing plate 221 into a third sub-plate 2211 and a fourth sub-plate 2212. The portion of the first reference electrode 213 located on the first sub-plate 2111 is called the first sub-reference electrode 2131, and the portion of the first reference electrode 213 located on the second sub-plate 2112 is called the second sub-reference electrode 2132; the portion of the second reference electrode 223 located on the third sub-plate 2211 is called the third reference electrode 2231, and the portion of the second reference electrode 223 located on the fourth sub-plate 2212 is called the fourth reference electrode 2232.

[0097] Since the first balun assembly 21 and the second balun assembly 22 are fixed to the reflector 1 and the radiation layer 23 at their respective ends, a first connecting portion 214 and a second connecting portion 215 can be provided at both ends of the first sub-plate 2111 along the thickness direction of the reflector 1, a third connecting portion 216 and a fourth connecting portion 217 can be provided at both ends of the second sub-plate 2112 along the thickness direction of the reflector 1, a fifth connecting portion 224 and a sixth connecting portion 225 can be provided at both ends of the third sub-plate 2211 along the thickness direction of the reflector 1, and a seventh connecting portion 226 and an eighth connecting portion 227 can be provided at both ends of the fourth sub-plate 2212 along the thickness direction of the reflector 1. Correspondingly, four through holes can be provided on the reflector 1 corresponding to the first connecting portion 214, the third connecting portion 216, the fifth connecting portion 224 and the seventh connecting portion 226. The first connecting portion 214, the third connecting portion 216, the fifth connecting portion 224 and the seventh connecting portion 226 are fixed to the reflector 1 through the four through holes provided on the reflector 1 respectively. Similarly, four vias corresponding to the second connecting portion 215, the fourth connecting portion 217, the sixth connecting portion 225, and the eighth connecting portion 227 can be provided on the radiation layer 23. The second connecting portion 215, the fourth connecting portion 217, the sixth connecting portion 225, and the eighth connecting portion 227 are fixed to the radiation layer 23 through the four vias provided on the radiation layer 23 respectively.

[0098] Furthermore, FIG11 is a top view of the reflector of the present disclosure embodiment; as shown in FIG11, the four through holes of the reflector 1 include two first through holes 11 and two second through holes 12, wherein the two first through holes 11 are respectively corresponding to the first connecting part 214 and the third connecting part 216, and the two second through holes 12 are respectively corresponding to the fifth connecting part 224 and the seventh connecting part 226.

[0099] In some examples, FIG12 is a top view of the radiating layer 23 of an embodiment of the present disclosure; as shown in FIG12, the radiating layer 23 includes a third fixing plate 231 and four radiating portions disposed on the side of the third fixing plate 231 opposite to the reflector 1, namely a first radiating portion 232a, a second radiating portion 232b, a third radiating portion 232c, and a fourth radiating portion 232d. The first radiating portion 232a, the second radiating portion 232b, the third radiating portion 232c, and the fourth radiating portion 232d can be arranged in an array. Among them, the first radiating portion 232a is electrically connected to the first sub-reference electrode 2131, the second radiating portion 232b is electrically connected to the second sub-reference electrode 2132, the third radiating portion 232c is electrically connected to the third sub-reference electrode 2231, and the fourth radiating portion 232d is electrically connected to the fourth sub-reference electrode 2232.

[0100] In this case, the four vias on the radiating layer 23 are a third via 233 penetrating the third fixing plate 231 and the first radiating part 232a, a fourth via 234 penetrating the third fixing plate 231 and the second radiating part 232b, a fifth via 235 penetrating the third fixing plate 231 and the third radiating part 232c, and a sixth via 236 penetrating the third fixing plate 231 and the fourth radiating part 232d. At this time, the first sub-reference electrode 2131 is connected to the first radiating part 232a through the third via 233, and the two can be connected by welding. Similarly, the second sub-reference electrode 2132 is connected to the second radiating part 232b through the fourth via 234, and the two can be connected by welding. The third sub-reference electrode 2231 is connected to the third radiating part 232c through the fifth via 235, and the two can be connected by welding. The fourth sub-reference electrode 2232 is connected to the fourth radiating part 232d through the sixth via 236, and the two can be connected by welding.

[0101] In some examples, the first radiating part 232a, the second radiating part 232b, the third radiating part 232c, and the fourth radiating part 232d are joined together to form a radiating surface. The first radiating part 232a, the second radiating part 232b, the third radiating part 232c, and the fourth radiating part 232d include, but are not limited to, polygons (e.g., squares, rectangles, hexagons), circles, etc.

[0102] In some examples, FIG13 is a front view of another embodiment of the present disclosure where a high-frequency vibrator 101 is fixed to a reflector 1; as shown in FIG13, the high-frequency vibrator 101 not only includes the above-described structure, but may also include a guide portion 24 disposed on the side of each radiating portion away from the reflector 1.

[0103] The above is an exemplary structure of a high-frequency oscillator 101 in an embodiment of this disclosure.

[0104] Figure 14 is a front view of the low-frequency oscillator 102 and the reflector 1 fixed according to an embodiment of this disclosure. As shown in Figure 14, the low-frequency oscillator 102 can adopt a structure similar to that of the high-frequency oscillator 101, or it can be slightly different from the high-frequency oscillator 101. In the low-frequency oscillator 102 of this disclosure, the connection between the first radiating part 232a and the first sub-reference electrode 2131, the connection between the second radiating part 232b and the second sub-reference electrode 2132, the connection between the third radiating part 232c and the third sub-reference electrode 2231, and the connection between the fourth radiating part 232d and the fourth sub-reference electrode 2232 are not direct connections. In the low-frequency oscillator 102, a coupling layer 25 is installed on the side of the first balun assembly and the second balun assembly away from the reflector 1. A first sub-reference electrode 2131, a second sub-reference electrode 2132, a third sub-reference electrode 2231, and a fourth sub-reference electrode 2231 are directly connected to the coupling layer 25 through through-holes. A first radiating part 232a is coupled to the first sub-reference electrode 2131 through the coupling layer 25. A second radiating part 232b is coupled to the second sub-reference electrode 2132 through the coupling layer 25. A third radiating part 232c is coupled to the third sub-reference electrode 2231 through the coupling layer 25. A fourth radiating part 232d is coupled to the fourth sub-reference electrode 2232 through the coupling layer 25.

[0105] In some examples, FIG15a is a top view of the radiating portion of the low-frequency oscillator 102 according to an embodiment of the present disclosure; as shown in FIG15a, the radiating portion 232 of the low-frequency oscillator 102 includes a first side S1, a second side S2, a third side S3, a fourth side S4 and multiple connecting edges; the first side S1 and the second side S2 are connected to form a first apex, the third side S3 and the fourth side S4 are connected to form a second apex, at least one connecting edge is connected between the first side S1 and the third side S3, and at least one connecting edge is connected between the second side S2 and the fourth side S4; the first apex and the second apex are arranged opposite to each other; the first apex of the first radiating portion 232a is opposite to the first apex of the second radiating portion 232b, and the first apex of the third radiating portion 232c is opposite to the first apex of the fourth radiating portion 232d. In Figure 17, taking the example of a hexagonal radiating section connected by a connecting edge S5 between the first side S1 and the third side S3, and a connecting edge S6 between the second side S2 and the fourth side S4, this method extends the current path and reduces insertion loss.

[0106] In other examples, FIG15b is a top view of the radiating layer 23 of the low-frequency oscillator 102 according to an embodiment of the present disclosure. As shown in FIG15b, the outline of the radiating portion 102 is the same as that in FIG15a, except that slots 230 are provided in the middle region and on the sides of the radiating portion 232 to improve the coupling between the high-frequency oscillator 101 and the low-frequency oscillator 102. The slots 230 on the radiating portion 232 are symmetrically arranged about the diagonal of the first apex and the second apex as the axis of symmetry, and are rotationally symmetrical about any two adjacent radiating portions 232 to avoid the radiation pattern shift.

[0107] It should be noted that the above are merely exemplary structures of the high-frequency oscillator 101 and the low-frequency oscillator 102 in this embodiment of the present disclosure. The high-frequency oscillator 101 and the low-frequency oscillator 102 in this embodiment of the present disclosure can also adopt any other structure. Therefore, the above structure does not constitute a limitation on the protection scope of this embodiment of the present disclosure.

[0108] In some examples, continuing to refer to Figure 1, for each antenna element 100, along the arrangement direction of the antenna element 100, the high-frequency vibrator 101 is divided into multiple columns. A first isolation component 103 is disposed between two adjacent columns of high-frequency vibrators, and a second isolation component 104 is disposed around the high-frequency vibrator 101. Both the first isolation component 103 and the second isolation component 104 are disposed on the reflector 1, and the orthographic projection of a high-frequency vibrator 101 on the reflector 1 lies within the orthographic projection of a second isolation component 104 on the reflector 1. Both the first isolation component 103 and the second isolation component 104 can prevent mutual interference between the high-frequency vibrator 101 and the low-frequency vibrator 102. Further, the second isolation component 104 can specifically be a ring-shaped fence structure formed by sequentially splicing isolation plates, for example, a square fence structure formed by sequentially splicing four isolation plates.

[0109] Figure 16 is a perspective view of the antenna unit 100 according to an embodiment of the present disclosure; Figure 17 is a top view of the antenna unit 100 according to an embodiment of the present disclosure; Figure 18 is a front view of the antenna unit 100 according to an embodiment of the present disclosure; Figure 19 is a top view of the decoupling structure 6 according to an embodiment of the present disclosure; as shown in Figures 16-19, an antenna device is provided in this embodiment of the present disclosure. The antenna device includes a reflector 1 and a plurality of vibrators disposed on the reflector 1, wherein some vibrators are high-frequency vibrators 101 and others are low-frequency vibrators 102. The antenna device is divided into a working area and a peripheral area surrounding the working area; the plurality of vibrators are located in the working area. In particular, the antenna device of this embodiment of the present disclosure also includes a decoupling structure 6 disposed on the reflector 1; the decoupling structure 6 is located in the peripheral area and is disposed on at least one side of the working area. The plane where the decoupling structure 6 is located has a certain angle with the plane where the reflector 1 is located; specifically, the decoupling structure 6 includes multiple conductive lines 61 and conductive patches 62 that are electrically connected to adjacent conductive lines 61; wherein, at least some of the multiple conductive lines 61 are located in different layers; for two conductive lines 61 located in different layers and electrically connected, the two conductive lines 61 are respectively connected to two conductive patches 62, and the two conductive patches 62 are coupled.

[0110] It should be noted that Figure 16 only shows an example where the plane containing the decoupling structure 6 is orthogonal to the plane containing the reflector 1. However, in actual products, the angle between the plane containing the decoupling structure 6 and the plane containing the reflector 1 may not be equal to 90°. The angle between the plane containing the decoupling structure 6 and the plane containing the reflector 1 can be set according to the specific business scenario.

[0111] The antenna device in this embodiment includes a decoupling structure 6. The decoupling structure 6 effectively reduces mutual interference between the high-frequency vibrator 101 and the low-frequency vibrator 102, thereby improving the antenna's radiation performance. The number of conductive lines 61 and conductive patches 62 in the decoupling structure 6 depends on the frequency points to be improved in the service scenario where the antenna device is applied. Specific examples will illustrate this below.

[0112] In some examples, the decoupling structure 6 is set on both sides of the arrangement direction of the antenna element 100, and each antenna element 100 is provided with a decoupling structure 6 on both sides of the arrangement direction of the antenna element 100. That is, each antenna element 100 is provided with two decoupling structures 6, and each decoupling structure 6 located on the same side of the arrangement direction of the antenna element 100 is set independently. The reason for this setting is to facilitate the fabrication of the decoupling structure 6.

[0113] In some examples, the decoupling structure 6 can be mounted on the reflector 1 via a support assembly, in which case there is a certain distance between the decoupling structure 6 and the reflector 1. The support assembly is made of insulating material, such as plastic.

[0114] In some examples, the conductive line 61 comprises multiple sequentially connected connecting segments 611, and at least some of the connecting segments 611 extend in different directions. That is, the conductive line 61 is a bent trace, and the shape of the conductive line 61 will be described in detail later.

[0115] To better illustrate the performance improvement of the decoupling structure 6 in the antenna device of this embodiment, the antenna device of this embodiment will be described in conjunction with the specific structure of the decoupling structure 6. The following description will use an example where the antenna device employs the aforementioned high-frequency vibrator 101 and low-frequency vibrator 102, and each antenna element 100 is provided with two decoupling structures 6.

[0116] First Example: Figure 20 is a schematic diagram of the first surface side of the first dielectric substrate 63 of the decoupling structure 6 in the first example; Figure 21 is a schematic diagram of the second surface side of the first dielectric substrate 63 of the decoupling structure 6 in the first example; as shown in Figures 19-21, in this example, the decoupling structure 6 includes not only multiple conductive lines 61 and conductive patches 62, but also the first dielectric substrate 63. Specifically, a portion of the multiple conductive lines 61 is a first conductive line 61a, and another portion is a second conductive line 61b, with the first conductive lines 61a and the second conductive lines 61b alternately arranged. The conductive patches 62 include a first conductive patch 621 and a second conductive patch 622. The first dielectric substrate includes a first surface and a second surface disposed opposite to each other along its thickness direction; the first conductive lines 61a and the first conductive patches 621 are located on the first surface, and the second conductive lines 61b and the second conductive patches 622 are located on the second surface. For the first conductive line 61a and the second conductive line 61b, which are arranged adjacently by orthographic projection on the plane of the first surface, the first conductive line 61a is connected to the first conductive patch 621, and the second conductive line 61b is connected to the second conductive patch 622; the orthographic projections of the first conductive patch 621 and the second conductive patch 622 on the plane of the first surface at least partially overlap. That is, some of the multiple conductive lines 61 are located on different sides of the reflector 1, and the conductive lines 61 located on different sides are coupled and connected through their respective connected conductive patches 62.

[0117] Furthermore, in this example, only three conductive lines 61 are used: two are first conductive lines 61a, and one is a second conductive line 61b. The corresponding number of conductive patches 62 is two. The conductive lines 61 in this example include multiple connecting segments 611, which include a first connecting segment 611a extending in a first direction and a second connecting segment 611b extending in a second direction. The first connecting segments 611a and 611b are alternately arranged and connected to form a square wave-shaped conductive line 61. That is, each connecting line is square wave-shaped. The conductive patches 62 are square, and the corresponding first conductive patch 621 and second conductive patch 622 are both square. Of course, the conductive patches 62 can also use other shapes, such as circles, hexagons, octagons, etc.

[0118] The antenna element 100 using the above-described decoupling structure 6 is simulated. Figure 22a shows the simulation results of the voltage standing wave ratio (VSWR) of each port of the high-frequency antenna array in the antenna element 100 of the first example; Figure 22b shows the simulation results of the directivity coefficient of the high-frequency antenna array in the antenna element 100 of the first example in the range of 1.69 to 2.69 GHz; Figure 22c shows the simulation results of the voltage standing wave ratio (VSWR) of each port of the low-frequency vibrator 102 in the antenna element 100 of the first example; Figure 22d shows the simulation results of the antenna element 100 of the first example. Simulation diagrams of the directivity coefficient of the low-frequency vibrator 102 in the range of 0.69 to 0.96 GHz are shown in Figures 22a and 22b. From the simulation results, the voltage standing wave ratio (VSWR) of each port of the high-frequency antenna array composed of the high-frequency vibrator 101 is less than 1.7, and the directivity coefficient in the range of 1.69 to 2.69 GHz is 11.9 to 13.9 dB; the voltage standing wave ratio (VSWR) of each port of the low-frequency vibrator 102 is less than 1.5, and the directivity coefficient in the range of 0.69 to 0.96 GHz is 8.0 to 8.5 dB. The antenna device including the three antenna elements 100 described above was simulated. Figure 23a is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the low-frequency antenna array in the antenna device of the first example; Figure 23b is a simulation diagram of the directivity coefficient of the low-frequency antenna array in the antenna device of the first example in the range of 0.69 to 0.96 GHz. As shown in Figures 23a and 23b, the simulation results show that the VSWR of each port of the low-frequency antenna array composed of the low-frequency vibrator 102 is less than 1.6, and the directivity coefficient in the range of 0.69 to 0.96 GHz is 11.9 to 13.1 dB.

[0119] The second example: Figure 24 is a top view of the decoupling structure 6 of the second example of the present disclosure; Figure 25 is a schematic diagram of the first surface side of the first dielectric substrate 63 of the decoupling structure 6 of the second example; Figure 26 is a schematic diagram of the second surface side of the first dielectric substrate 63 of the decoupling structure 6 of the second example; As shown in Figures 25-26, this example is substantially the same as the structure of the first example, except that the decoupling structure 6 of this example has five conductive lines 61 and four corresponding conductive patches 62. The five conductive lines 61 include three first conductive lines 61a and two second conductive lines 61b.

[0120] The antenna element 100 using the above-mentioned decoupling structure 6 was simulated. Figure 27a is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the high-frequency antenna array in the second example antenna element 100; Figure 27b is a simulation diagram of the directivity coefficient of the high-frequency antenna array in the second example antenna element 100 in the range of 1.69 to 2.69 GHz; Figure 27c is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the low-frequency antenna array in the second example antenna device; Figure 27d is a simulation diagram of the directivity coefficient of the low-frequency antenna array in the second example antenna device in the range of 0.69 to 0.96 GHz. As shown in Figures 27a to 27d, the simulation results show that the voltage standing wave ratio of each port of the high-frequency antenna array composed of the high-frequency vibrator 101 is less than 1.7, and the directivity coefficient in the range of 1.69 to 2.69 GHz is 11.9 to 13.9 dB. Simulations were performed on the antenna device comprising the three antenna elements 100 described above. The simulation results show that the voltage standing wave ratio (VSWR) at each port of the low-frequency antenna array composed of the low-frequency vibrator 102 is less than 1.5, and the directivity coefficient in the range of 0.69–0.96 GHz is 11.9–13.1 dB. Combining the simulation results of the first example, it can be seen that the different decoupling structures 6 have slightly different effects on the various frequency points of the high- and low-frequency antenna arrays. In the second example, although the directivity coefficient of the high-frequency antenna array is slightly higher near 2.17 GHz, its bandwidth is relatively narrow, and the directivity coefficient decreases slightly after accounting for bandwidth differences. The directivity coefficient curve of the low-frequency antenna array is not as smooth as in the first example, and the directivity coefficient is slightly lower at 894 MHz. Although its bandwidth increases, it still decreases slightly after accounting for bandwidth differences.

[0121] The third example: Figure 28 is a top view of the decoupling structure 6 of the third example of the present disclosure. As shown in Figure 28, the decoupling structure 6 in this example differs from the above two examples in that it adopts a metal structure. The first dielectric substrate 63 is no longer provided in this example, and there is an air gap between the conductive lines 61 located on different layers. In this case, the conductive lines 61 and the conductive patches 62 connected to them can be fixed to the reflector by a support assembly. Specifically, the support assembly can be an insulating component.

[0122] The antenna element 100 using the above-mentioned decoupling structure 6 was simulated. Figure 29a is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the high-frequency antenna array in the antenna element 100 of the third example; Figure 29b is a simulation diagram of the directivity coefficient of the high-frequency antenna array in the antenna element 100 of the third example in the range of 1.69 to 2.69 GHz; Figure 29c is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the low-frequency antenna array in the antenna device of the third example; Figure 29d is a simulation diagram of the directivity coefficient of the low-frequency antenna array in the antenna device of the third example in the range of 0.69 to 0.96 GHz. As shown in Figures 29a to 29d, the simulation results show that the voltage standing wave ratio of each port of the high-frequency antenna array composed of the high-frequency vibrator 101 is less than 1.7, and the directivity coefficient in the range of 1.69 to 2.69 GHz is 11.8 to 13.8 dB. Simulations were performed on the antenna device comprising the three antenna elements 100 described above. The simulation results show that the voltage standing wave ratio (VSWR) at each port of the low-frequency antenna array composed of the low-frequency vibrator 102 is less than 1.5, and the directivity coefficient is 12.0–13.2 dB in the range of 0.69–0.96 GHz. Combining the simulation results of the first example, it can be seen that although the directivity coefficient of the high-frequency antenna array in the third example is slightly higher at 2.155 GHz, its bandwidth is relatively narrow, and the directivity coefficient decreases slightly after accounting for bandwidth differences. The directivity coefficient curve of the low-frequency antenna array is not as smooth as that of the first example; although the directivity coefficient is slightly higher at 894 MHz, it remains essentially unchanged after accounting for bandwidth differences.

[0123] Fourth Example: Figure 30 is a top view of the decoupling structure 6 of the fourth example of the present disclosure. As shown in Figure 30, only the conductive lines 61 and conductive patches 62 located on the first and second surfaces of the first dielectric substrate 63 are schematically shown as orthographic projections on the first or second surface of the first dielectric substrate 63. The structure of this example is roughly the same as that of the first example, except that in this example decoupling structure 6, the extension directions of adjacent second connecting segments 611b in the conductive lines 61 are different. Specifically, the extension lines of the odd-numbered first connecting segments 611a coincide, and the extension lines of the even-numbered first connecting segments 611a coincide; the spacing d1 between the odd-numbered first connecting segments 611a is greater than the length d2 of the even-numbered first connecting segments 611a.

[0124] The antenna element 100 using the above-mentioned decoupling structure 6 was simulated. Figure 31a is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the high-frequency antenna array in the antenna element 100 of the fourth example; Figure 31b is a simulation diagram of the directivity coefficient of the high-frequency antenna array in the antenna element 100 of the fourth example in the range of 1.69 to 2.69 GHz; Figure 31c is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the low-frequency antenna array in the antenna device of the fourth example; Figure 31d is a simulation diagram of the directivity coefficient of the low-frequency antenna array in the antenna device of the fourth example in the range of 0.69 to 0.96 GHz. As shown in Figures 31a to 31d, the simulation results show that the voltage standing wave ratio of each port of the high-frequency antenna array composed of the high-frequency vibrator 101 is less than 1.7, and the directivity coefficient in the range of 1.69 to 2.69 GHz is 11.7 to 14.0 dB. Simulations were performed on the antenna device comprising the three antenna elements 100 described above. The simulation results show that the voltage standing wave ratio (VSWR) at each port of the low-frequency antenna array composed of the low-frequency vibrator 102 is less than 1.5, and the directivity coefficient is 12.0–13.3 dB in the range of 0.69–0.96 GHz. Combining the simulation results of the first example, it can be seen that while the directivity coefficient of the high-frequency antenna array in the fourth example is slightly higher at 2.155 GHz and 2.17 GHz, its radiation pattern distortion is relatively large at 2.3 GHz. The directivity coefficient of the low-frequency antenna array does not change significantly after accounting for the difference in bandwidth, but the bandwidth at some frequency points is relatively narrow.

[0125] Fifth Example: Figure 32 is a top view of the decoupling structure 6 of the fifth example of this disclosure. As shown in Figure 32, only the conductive lines 61 and conductive patches 62 located on the first and second surfaces of the first dielectric substrate 63 are schematically shown as orthographic projections onto the first or second surface of the first dielectric substrate 63. The structure of this example is largely the same as that of the first example, except that in this example of decoupling structure 6, the conductive lines 61 are wavy lines, such as sine curves, and the conductive patches 62 are circular. Of course, the conductive patches 62 can also be other shapes, such as squares, hexagons, octagons, etc.

[0126] The antenna element 100 using the above-mentioned decoupling structure 6 was simulated. Figure 33a is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the high-frequency antenna array in the antenna element 100 of the fifth example; Figure 33b is a simulation diagram of the directivity coefficient of the high-frequency antenna array in the antenna element 100 of the fifth example in the range of 1.69 to 2.69 GHz; Figure 33c is a simulation diagram of the voltage standing wave ratio (VSWR) of each port of the low-frequency antenna array in the antenna device of the fifth example; Figure 33d is a simulation diagram of the directivity coefficient of the low-frequency antenna array in the antenna device of the fifth example in the range of 0.69 to 0.96 GHz. As shown in Figures 33a to 33d, the simulation results show that the voltage standing wave ratio of each port of the high-frequency antenna array composed of the high-frequency vibrator 101 is less than 1.7, and the directivity coefficient in the range of 1.69 to 2.69 GHz is 11.7 to 14.0 dB. Simulations were performed on the antenna device comprising the three antenna elements 100 described above. The simulation results show that the voltage standing wave ratio (VSWR) at each port of the low-frequency antenna array composed of the low-frequency vibrator 102 is less than 1.5, and the directivity coefficient in the range of 0.69–0.96 GHz is 12.0–13.3 dB. Combining the simulation results of the first example, it can be seen that although the directivity coefficient of the high-frequency antenna array in the fifth example is slightly improved at some frequency points after accounting for the bandwidth difference, its radiation pattern distortion at 2.3 GHz is relatively large. The low-frequency antenna array does not change much after accounting for the bandwidth difference, but the bandwidth at some frequency points is relatively narrow.

[0127] Sixth Example: Figure 34 is a schematic diagram of the first surface side of the first dielectric substrate of the sixth example decoupling structure 6; Figure 35 is a schematic diagram of the second surface side of the first dielectric substrate of the sixth example decoupling structure 6; as shown in Figures 34 and 35, in this example, the decoupling structure 6 includes a first dielectric substrate 63, multiple conductive lines 61, and conductive patches 62. The first dielectric substrate 63 includes a first surface and a second surface disposed opposite to each other along its thickness direction. The conductive lines 61 are square-wave shaped. The conductive lines 61 include a first sub-conductive line 61 disposed on the first surface and a second sub-conductive line 61 disposed on the second surface; the first sub-conductive line 61 includes a first conductive pattern disposed at intervals, and the second sub-conductive line 61 includes a second conductive pattern disposed at intervals; the first conductive pattern includes a first connecting segment extending along a first direction, and a second connecting segment connected to both ends of the first connecting segment and extending along the first direction; the second conductive pattern includes a third connecting segment extending along the first direction, and a fourth connecting segment connected to both ends of the first connecting segment and extending along the first direction. For a conductive line 61, at least a portion of the second connecting segment of the first conductive line and at least a portion of the fourth connecting segment of the second conductive line are provided in a one-to-one correspondence, and the orthographic projections of the corresponding second connecting segment and the fourth connecting segment on the first dielectric substrate at least partially overlap.

[0128] The conductive patch 62 includes a first conductive patch 621 and a second conductive patch 622. The first conductive patch 621 is disposed in the same layer as the first conductive pattern, and the second conductive patch is disposed in the same layer as the second conductive pattern. The first conductive patch 621 and the second conductive patch 622 at least partially overlap in orthographic projection on the first dielectric substrate, so that the adjacent conductive lines 61 are electrically connected.

[0129] Seventh Example: Figure 36 is a top view of the decoupling structure 6 of the seventh example of the present disclosure. As shown in Figure 36, only the conductive lines 61 and conductive patches 62 located on the first and second surfaces of the first dielectric substrate 63 are schematically shown as orthographic projections onto the first or second surface of the first dielectric substrate 63. The structure of this example is substantially the same as that of the first example, except that the lengths of the second connecting segments in this example are at least partially unequal. For example, a coordinate axis is established with the first direction as the abscissa and the second direction as the ordinate, with one end of each second connecting segment located on the abscissa, and the length of each second connecting segment satisfying a sine function.

[0130] It should be noted that the above are only a few exemplary decoupling structures 6. Any variations or combinations of the above structures are within the protection scope of the embodiments disclosed herein.

[0131] This disclosure provides an electronic device that may include the antenna device described above.

[0132] The antenna device provided in this disclosure also includes a transceiver unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filtering unit. The antenna in the antenna system can function as either a transmitting antenna or a receiving antenna. The transceiver unit may include a baseband and a receiving end. The baseband provides signals in at least one frequency band, such as 2G, 3G, 4G, and 5G signals, and transmits these signals to the radio frequency transceiver. After receiving the signal, the antenna in the antenna system processes it through the filtering unit, power amplifier, signal amplifier, and radio frequency transceiver before transmitting it to the receiving end in the transmitting unit. The receiving end may be, for example, a smart gateway.

[0133] Furthermore, the RF transceiver is connected to the transceiver unit and is used to modulate the signals transmitted by the transceiver unit, or to demodulate the signals received by the antenna before transmitting them to the transceiver unit. Specifically, the RF transceiver may include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives various types of signals provided by the baseband, the modulation circuit can modulate the various types of signals provided by the baseband and then send them to the antenna. The antenna receives the signals and transmits them to the receiving circuit of the RF transceiver. The receiving circuit then transmits the signals to the demodulation circuit, which demodulates the signals and transmits them to the receiving end.

[0134] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, which are then connected to a filtering unit. The filtering unit is connected to at least one antenna. During signal transmission, the signal amplifier improves the signal-to-noise ratio (SNR) of the RF transceiver's output signal before transmitting it to the filtering unit; the power amplifier amplifies the power of the RF transceiver's output signal before transmitting it to the filtering unit. The filtering unit may include a duplexer and a filtering circuit. The filtering unit combines the signals output from the signal amplifier and power amplifier, filters out clutter, and transmits them to the antenna, which then radiates the signal. During signal reception, the antenna receives the signal and transmits it to the filtering unit. The filtering unit filters out clutter from the received signal before transmitting it to the signal amplifier and power amplifier. The signal amplifier increases the gain of the received signal, improving the SNR; the power amplifier amplifies the power of the received signal. The received signal is then processed by the power amplifier and signal amplifier before being transmitted to the RF transceiver, which in turn transmits it to the transceiver unit.

[0135] In some examples, the signal amplifier may include various types of signal amplifiers, such as low-noise amplifiers, without limitation.

[0136] In some examples, the antenna device provided in this disclosure embodiment further includes a power management unit connected to a power amplifier and providing the power amplifier with a voltage for amplifying the signal.

[0137] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
