Description

TECHNICAL FIELD

[0001] The present disclosure relates to, but is not limited to, the field of communication, and in particular, to an antenna structure and a communication system. BACKGROUND

[0002] Dual-polarized omni-directional antenna is a new type of antenna technology, which combines two pairs of polarization directions of +45° and -45° orthogonal to each other and works in a transceiver duplex mode, so the most prominent advantage is to save the number of antennas of a single directional base station.

[0003] At present, the structure of the dual-polarized omni-directional antenna is complex, the cost is high, and it is not convenient to disassemble and assemble. In order to ensure the gain, the number of antenna units needs to be increased, which leads to the large overall size of the dual-polarized omni-directional antenna, the large windward surface, and the greater possibility of damage by the natural environment.

[0077] like Figure 1 An antenna structure shown may include two antenna assemblies 1 spaced apart in a first direction. The two antenna assemblies 1 may be arranged symmetrically about a first plane 9 located between the two antenna assemblies 1, with the first direction being perpendicular to the first plane. The antenna assembly 1 may include at least two spaced-apart antenna units 2. Each antenna unit 2 may include a connected reflector 4 and a patch mechanism 5. The patch mechanism 5 may be located on the side of the reflector 4 facing away from the first plane 9. Thus, this antenna structure, using only two antenna assemblies 1, can achieve omnidirectional coverage. Compared to related dual-polarized omnidirectional antennas, it maintains gain while maintaining a smaller size and simpler structure.

[0078] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the two antenna components 1 are arranged symmetrically about the first plane 9, the distances between the two antenna components 1 and the first plane 9 are equal, and the distance between the two antenna components 1 is set to D. In this example, the value of D can be set to 40 mm, but is not limited thereto. For example, the value of D can be other values ​​greater than 10 mm.

[0079] In some exemplary embodiments, Figure 1 and Figure 2 As shown, in addition to the antenna unit 2, the antenna assembly 1 may also include a connector 3. The reflectors 4 of two adjacent antenna units 2 may be configured to be connected via the connector 3. The two adjacent antenna units 2 may be configured to be symmetrically arranged according to the connector 3. The connector 3 and the two connected reflectors 4 may be an integral part, but are not limited thereto. For example, the connector 3 and the two connected reflectors 4 may be detachably connected by plugging, snapping, etc. With respect to a single antenna assembly 1, the antenna assembly 1 includes two antenna units 2, which are spaced apart in the second direction. The reflectors 4 of the two antenna units 2 may both be located on a second plane, which is parallel to the first plane 9. The second direction is perpendicular to the first direction and parallel to the first plane 9. The number of antenna units 2 is not limited to two. The following uses two antenna units as an example to describe the antenna structure.

[0080] In some exemplary embodiments, Figure 1 and Figure 3 As shown, the reflector 4 can be made of metal and can be set to a square plate shape. In this example, the reflector 4 can be a copper plate. The thickness of the reflector 4 is h. The four edges of the reflector 4 are perpendicular to each other and have the same extension length. Figure 7 The size in the second direction is set to L6, and the size in the third direction is set to L 11L6 = L 11 L6 = L 11 L6 = L 11 The four circumferential edges of the reflector plate 4 include a third edge 11 away from the connecting piece 3, the third edge 11 extends along a third direction, the third direction is perpendicular to the first direction and the second direction. The shape of the reflector plate 4 is not limited to a square plate, for example, the reflector plate 4 can also be a rectangular plate, the size of the reflector plate 4 in the second direction is not equal to the size of the reflector plate 4 in the third direction, for example, the reflector plate 4 is a rhombic plate, and so on, the four circumferential edges of the reflector plate 4 are no longer perpendicular to each other.

[0081] In some example embodiments, as shown in Figure 1 and Figure 3 , the connecting piece 3 can be made of metal and in the form of a plate, in this example, the connecting piece 3 can be a copper plate, and the connecting piece 3 can be in the second plane, that is, the connecting piece 3 and the reflector plate 4 are coplanar. The thickness of the connecting piece 3 can be the same as the thickness of the reflector plate 4, both of which are h, so that the connecting piece 3 and the two reflector plates 4 can be formed by a copper plate with a thickness of h, which is convenient for production. The connecting piece 3 can be rectangular, and the four circumferential edges of the connecting piece can include two first edges 10 (the dashed line positions in Figure 3 ) respectively located at the two ends of the connecting piece 3 in the second direction, the extension length of the first edge 10 is set to be the size L 14 of the connecting piece 3 in the third direction, and the two first edges 10 are respectively connected to the two reflector plates 4, and the first edge 10 extends along the third direction. The edge of the circumferential edge of the reflector plate 4 away from the third edge 11 is connected to the first edge 10, and the extension length of the third edge 11 and the first edge 10 in the third direction is consistent, that is, L 14 in Figure 3 is equal to L 11 in Figure 7 , so that the two ends of the connecting piece 3 and the reflector plate 4 in the third direction are flush, and it can be known that the copper plate forming the connecting piece 3 and the two reflector plates 4 is rectangular. In addition, the size of the connecting piece 3 in the second direction can be L 15 , wherein the value of L 15 is set to be equal to the value of L 14 , so that the connecting piece 3 is also square, but it is not limited thereto, the size of the connecting piece 3 in the second direction (L 15 ) can be greater than or less than the size of the connecting piece in the third direction (L 14 ), forming a rectangle.

[0082] In some example embodiments, as shown inFigure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the patch mechanism 5 may include a dielectric plate 6 and a radiating patch 7. The radiating patch 7 may be arranged parallel to the reflector 4 and spaced apart from the reflector 4 in the first direction. The dielectric plate 6 is sandwiched between the radiating patch 7 and the reflector 4. The reflector 4, dielectric plate 6, and radiating patch 7 can be assembled as a whole using a printed circuit board process, resulting in low-cost and easy production. The use of the patch mechanism 5 enables the antenna structure to be a microstrip patch antenna, which has the advantage of a low profile and can effectively reduce the overall thickness of the antenna. The dielectric plate 6 can be an FR4 substrate, and the radiating patch 7 can be a copper plate. The two radiating patches 7 are approximately 300 mm to 400 mm apart in the second direction. The dielectric plate 6 and radiating patch 7 are both arranged centered relative to the reflector 4, with the geometric centers of the reflector 4, dielectric plate 6, and radiating patch 7 aligned in a straight line extending along the first direction.

[0083] In some exemplary embodiments, Figure 5 and Figure 6 As shown, the dielectric plate 6 and the radiation patch 7 are also square plates. The four circumferential edges of the dielectric plate 6 are perpendicular to each other and have the same size. Two edges extend along the second direction and two edges extend along the third direction. The size of the dielectric plate 6 in the second direction is set to L5, and the size of the dielectric plate 6 in the third direction is set to L 10 , where the value of L5 is equal to L 10 The cross section of the dielectric plate 6 parallel to the first plane is a square, and the side length of the square is L5, or the side length is L 10 , the sides of the square extend along the second direction and the third direction respectively. The four circumferential edges of the radiation patch 7 are perpendicular to each other, two edges extend along the second direction, and two edges extend along the third direction. The size of the radiation patch 7 in the second direction is set to L2, and the size of the radiation patch 7 in the third direction is set to L9, where the value of L2 is equal to the value of L9. The cross-section of the radiation patch 7 parallel to the first plane is a square, and the side length of the square is L2, or called the side length L9, and the side lengths of the square extend along the second direction and the third direction respectively. Among them, the edge length of the dielectric plate 6 can be greater than the edge length of the radiation patch 7. It can be seen that L2=L9<L 10 =L5. Figure 5 and Figure 6 Based on the combination Figure 7 , we can see that the edge length of the dielectric plate 6 can be greater than the edge length of the radiation patch 7, and the edge length of the dielectric plate 6 can be less than the edge length of the reflector 4, that is, L2=L9<L5=L 10 <L6=L 11，The areas of the projections of the three square-shaped members on the first plane are in order from small to large: the radiation patch 7, the dielectric plate 6, and the reflecting plate 4. The projection of the dielectric plate 6 on the first plane can be arranged within the projection of the reflecting plate 4 on the first plane, and the projection of the radiation patch 7 on the first plane can be arranged within the projection of the dielectric plate 6 on the first plane. The edge size ratio of the radiation patch 7 and the dielectric plate 6 is L2:L5, and the ratio of L2 and L5 is between 1:1.33 and 1.07:1.12. The edge size ratio of the reflecting plate 4 and the dielectric plate 6 is L6:L5, and the ratio of L6 and L5 is between 1:2.1 and 1.19:1.39.

[0084] In some example embodiments, as shown in Figure 1 and Figure 3 The windward area of the antenna structure is approximately the cross section of the copper plates constituting the connecting plate 3 and the two reflecting plates 4 that is parallel to the first plane 9, and the area of the cross section is equal to the product of the length of the first edge length and the length of the second edge length. The length of the first edge length is the size of the connecting plate 3 and the two reflecting plates 4 in the second direction, and the length of the second edge length is the size of the connecting plate 3 or the reflecting plate 4 in the third direction. The windward area can be approximately between 0.1 m 2 and 0.15 m 2 In this example, the windward area can be 0.12 m 2 , which is much smaller than the standard windward area (0.8 m2), and thus the antenna structure has a small windward area and is less affected by the external environment such as wind and rain, and the risk of damage from the natural environment can be reduced.

[0085] In some example embodiments, as shown in Figures 3 to 7As shown, the radiation patch 7 can have two feed ports 8 which are 90° rotationally symmetric about the geometric center of the radiation patch 7, the feed ports 8 can be coaxial feed ports 8, and the two feed ports 8 have a phase difference of 180°. The two feed ports 8 are respectively located on two diagonal lines C1 of the square radiation patch 7, forming ±45° dual polarization, and the feed mode is set to be a dual-port equal-radiation unequal-phase feed. The circumferential four edges of the radiation patch 7 include a second edge 15 located at one end of the radiation patch 7 in the third direction, the second edge 15 extends along the second direction, and the two feed ports 8 are arranged away from the second edge 15 and have equal distances from the second edge 15. The positions of the two feed ports 8 are not limited to this, for example, the two feed ports 8 are respectively located on the two diagonal lines C1, but are arranged away from the edges of other radiation patches 7. The feed port 8 can be composed of a copper tinned pad (not shown in the figure) and a coaxial metal inner core (not shown in the figure), and the cross section of the feed port 8 is circular. The copper tinned pad is provided with a through hole (not shown in the figure) for accommodating the coaxial metal inner core, the coaxial metal inner core penetrates through the radiation patch 7 and is welded on the front surface (the end surface facing away from the reflecting plate 4) of the radiation patch 7, and the other end of the coaxial metal inner core penetrates through the reflecting plate 4 to be connected and can be connected to a power divider (not shown in the figure) through a cable. The reflecting plate 4, the dielectric plate 6 and the radiation patch 7 are sequentially provided with a first through hole 12, a second through hole 13 and a third through hole 14 for the feed port 8 to penetrate through.

[0086] In some example embodiments, the antenna structure can include an insulating piece (not shown in the figure) and a shell (not shown in the figure), the two antenna assemblies 1 are connected through the insulating piece, the insulating piece can be a hexagonal nylon column, and holes need to be punched on the reflecting plates 4 or the connecting plates 3 of the two antenna assemblies 1 respectively, the insulating piece is correspondingly inserted into the holes to form a fixed installation of the antenna assembly 1. The two antenna assemblies 1 can be installed in the shell, the shell is slightly larger than the size of the antenna structure, and the antenna structure can also be positioned in the shell through the insulating piece.

[0087] In some example embodiments, Figure 30 is set to Figure 1 The Realizd Gain simulation schematic diagram of the antenna structure in Figure 29 is set to Figure 1 The antenna pattern simulation of the antenna structure in Figure 30 The abscissa axis in is the circumferential angle of the antenna, and the ordinate is the numerical value of the gain; the antenna pattern refers to the pattern of the relative field strength (normalized modulus) of the radiation field varying with the direction at a certain distance from the antenna, which is usually represented by two mutually perpendicular plane patterns in the maximum radiation direction of the antenna.

[0091] In some exemplary embodiments, Figure 11 As shown, a single antenna assembly 1 includes two antenna elements 2 spaced apart in the second direction. The reflectors 4 of the two antenna elements 2 lie in the same plane. The reflectors 4 can be square. In this example, the reflectors 4 and the connector 3 are both copper plates. The connector 3 also lies in the second plane, meaning the connector 3 and reflectors 4 are coplanar. The thickness of the connector 3 can be the same as that of the reflectors 4. Thus, the connector 3 and the two reflectors 4 are constructed from a single copper plate with a thickness of h, facilitating production. The connector 3 is rectangular, with its dimensions in the third direction being smaller than those of the reflectors 4. Furthermore, the connector 3 is centrally located in the third direction, and the copper plate comprising the two connectors 3 and the three reflectors 4 is I-shaped.

The phase difference between the two feeding ports 8 is 180°, forming ±45° dual polarization. The feeding mode is set to dual-port equal-radiation unequal-phase feeding. Figure 11 As shown, the frontal area of ​​the antenna structure is approximately the cross section of the copper plate forming a connector 3 and two reflectors 4 parallel to the first plane 9. In this example, the frontal area is smaller, approximately 0.1m 2 , relative to the antenna standard frontal area of ​​0.8m 2, which is also much smaller than the standard frontal area, ensuring that the antenna structure has a smaller frontal area and reducing the risk of damage from the natural environment. The reflector 4, dielectric plate 6, and radiating patch 7 can be assembled as a whole using printed circuit board technology, which is low-cost and easy to manufacture.

[0092] In some exemplary embodiments, Figure 12 As shown, a single antenna assembly 1 includes a reflector 4, a dielectric plate 6, and a radiating patch 7. The reflector 4, dielectric plate 6, and radiating patch 7 are all rectangular. The dimensions of the reflector 4, dielectric plate 6, and radiating patch 7 in the third direction are all larger than their respective dimensions in the second direction, but this is not limited to this. For example, the dimensions of the reflector 4, dielectric plate 6, and radiating patch 7 in the second direction are all larger than their respective dimensions in the third direction. The dimensions of the connecting plate 3 in the third direction are consistent with those of the reflector 4, so that the connecting plate 3 and the two reflectors 4 form a single copper plate.

The phase difference between the two feeding ports 8 is 180°, forming ±45° dual polarization. The feeding mode is set to dual-port equal-radiation unequal-phase feeding.

[0093] In some exemplary embodiments, Figure 13 and Figure 14 As shown, an antenna unit 2 includes a square reflector 4, a dielectric plate 6, and a radiation patch 7. The reflector 4, dielectric plate 6, and radiation patch 7 can be assembled as a whole using a PCB process, which is low-cost and easy to manufacture. The dielectric plate 6 and the radiation patch 7 are both arranged to be centered relative to the reflector 4. The two feeding ports 8 are respectively located on the two diagonals of the square radiation patch 7. The radiation patch 7 can be provided with a second slot 16, which is centrally arranged on the radiation patch 7 and passes through the radiation patch 7 in the thickness direction of the radiation patch 7. The geometric center of the second slot 16 coincides with the geometric center of the radiation patch 7, achieving a centered arrangement. The second slot 16 is configured as a cross-shaped slot, which includes a second transverse slot 17 and a second vertical slot 18 intersecting each other. The second transverse slot 17 and the second vertical slot 18 are perpendicular to each other, and the slot lengths of the second transverse slot 17 and the second vertical slot 18 are consistent, both being L1. The slot widths of the second transverse slot 17 and the second vertical slot 18 are consistent, and can be set between 1 mm and 2 mm. The slot depths of the second transverse slot 17 and the second vertical slot 18 are equal to the thickness of the radiation patch 7, so as to penetrate the radiation patch 7. Figure 5As shown, the radiation patch 7 is a square plate with a side length of L2, that is, the extension length of the radiation patch 7 in the second direction is set to L2, and combined with Figure 14 As shown, L1:L2=1:2, and the length of the second transverse slot 17 and the second vertical slot 18 is about half of the side length of the radiation patch 7. The antenna structure of this example changes the current distribution on the antenna by opening the second slot 16. The increase in the current path length makes the antenna produce a larger current path. Figure 1 The antenna structure shown has a lower resonance point at the resonance frequency, thereby expanding the bandwidth of the antenna. The second slot 16 is not limited to a cross-shaped slot, and can be, for example, L-shaped, but needs to be arranged centrally on the radiation patch 7.

[0094] In some exemplary embodiments, Figure 15 As shown, the antenna unit includes a square reflector 4, a dielectric plate 6, and a radiating patch 7. The reflector 4, dielectric plate 6, and radiating patch 7 can be assembled as a whole using a PCB process, which is low-cost and easy to manufacture. The dielectric plate 6 and radiating patch 7 are both arranged to be centered relative to the reflector 4. The radiating patch 7 can be provided with a second slot 16, which is centrally arranged on the radiating patch 7 and penetrates the radiating patch 7 in the thickness direction of the radiating patch 7. The geometric center of the second slot 16 coincides with the geometric center of the radiating patch 7, achieving a centered arrangement. The second slot 16 is configured as a cross-shaped slot, which includes two intersecting oblique slots 30. The two oblique slots 30 are perpendicular to each other, have the same slot length, and have the same slot width, which can be set between 1 mm and 2 mm. The slot depth of the two oblique slots 30 is equal to the plate thickness of the radiating patch 7, thereby penetrating the radiating patch 7. The radiation patch 7 may have two feeding ports 8 that are 90° rotationally symmetrical about the geometric center of the radiation patch 7. The feeding ports 8 may be coaxial feeding ports 8. The phase difference between the two feeding ports 8 is 180°, forming ±45° dual polarization. The feeding mode is set to dual-port equal-radiation unequal-phase feeding. Figure 15 As shown, the radiation patch 7 is a square plate with a side length. The length of the oblique slot 30 is about half of the side length of the radiation patch 7. One oblique slot 30 and a feeding port 8 are located on one diagonal line C1 of the radiation patch 7, and another oblique slot 30 and another feeding port 8 are located on another diagonal line C1 of the radiation patch 7. The antenna structure of this example changes the current distribution on the antenna by providing the second slot 16. The increase in the current path length causes the antenna to generate a current path length, such as Figure 1 The antenna structure shown ( Figure 1 The antenna structure shown does not have a second slot 16 ) to provide a resonance point with a lower resonance frequency, thereby extending the bandwidth of the antenna.

[0095] In some exemplary embodiments, Figure 16As shown, the antenna unit can include a square-shaped reflecting plate 4, a dielectric plate 6 and a radiation patch 7, which can be integrated by a printed circuit board process, and are low-cost and easy to manufacture.

As shown in Figure 16 As shown, the radiation patch 7 is a square plate with a side length of L2, i.e., the extension length of the radiation patch 7 in the third direction is set to L2, and in combination with Figure 16 As shown, L1:L2=1:2, and the slot length of the second horizontal slot 17 and the second vertical slot 18 is about half of the side length of the radiation patch 7. In the antenna structure of the present example, the second slot 16 is provided to change the current distribution on the antenna, and the increase in the current path length causes the antenna to generate a resonance point with a lower resonance frequency than the original resonance frequency, thereby expanding the bandwidth of the antenna. The second slot 16 is not limited to a T-shaped slot, and can be, for example, an H-shaped slot, but needs to be arranged centrally on the radiation patch 7. Figure 1 As shown, the antenna structure resonates at a lower resonance frequency, thereby expanding the bandwidth of the antenna. The second slot 16 is not limited to a T-shaped slot, and can be, for example, an H-shaped slot, but needs to be arranged centrally on the radiation patch 7.

[0096] In some example embodiments, as Figure 17As shown, the antenna unit includes a square reflector plate 4, a dielectric plate 6 and a radiation patch 7, which can be integrated by PCB process, low cost and easy to manufacture.

The slot length of the first vertical slot 21 and the first vertical slot 21 is consistent and less than the side length of the dielectric plate, both being L4, wherein L4 is about 0.9xL5; the slot depth and the slot width of the first vertical slot 21 and the first vertical slot 21 are consistent, wherein the slot width is 1mm to 1.5mm, and in this example, it is 1mm, and the slot depth of both is the thickness of the connecting plate 3. The dielectric plate 6 can adopt FR4 substrate, the radiation patch 7 and the reflector plate 4 can be copper plates, and the distance between the two radiation patches 7 in the second direction is about 300mm to 400mm. The dielectric plate 6 and the radiation patch 7 are also square plates, and the side lengths of the dielectric plate 6, the radiation patch 7 and the reflector plate 4 are arranged in order from large to small as the reflector plate 4, the dielectric plate 6 and the radiation patch 7.

The antenna structure of this example can improve the coupling effect between the two-sided antenna assembly 1 by increasing the first slot 19. Figure 31 As shown in the antenna pattern simulation diagram of the antenna structure, Figure 31 and Figure 29 compared with Figure 1The lowest gain of the antenna structure is improved from 4.16dB to 4.3dB, while the highest gain 11.17dB is reduced to 11.02dB, and the overall directivity is improved by about 0.3dB. The first slot 19 is not limited to the intersecting first horizontal slot 20 and first vertical slot 21, for example, the first slot 19 can only be a plurality of parallel first horizontal slots 20, and for example, only a plurality of parallel first vertical slots 21, which can increase the current path and reduce coupling.

[0097] In some example embodiments, as shown in Figure 18 The antenna unit includes a square reflector plate 4, a dielectric plate 6 and a radiation patch 7, which can be integrated by PCB process, low cost and easy to manufacture.

The second slot 16 is arranged as a cross-shaped slot, including intersecting second horizontal slot 17 and second vertical slot 18, and the second horizontal slot 17 and the second vertical slot 18 are perpendicular. The connecting piece 3 can have a first slot 19 arranged to penetrate the connecting piece 3 in a first direction, and the first slot 19 is arranged centrally on the connecting piece 3 and symmetrically relative to the geometric center of the connecting piece 3. If the first slot 19 is arranged eccentrically, it will affect the symmetry of the antenna.
