Description

Technical Field

[0001] This invention relates to the field of antenna technology, and in particular to an ultra-wide antenna reflector. Background Technology

[0002] Currently, mobile communication networks are in an era where 2G, 3G, 4G and 5G coexist. Mobile communication network operators are facing challenges such as scarce rooftop site resources, coexistence of multiple network standards and surging user demand. There is an urgent need for common-port antennas that combine multi-frequency, multi-port and miniaturized features.

[0003] In simple terms, a base station antenna consists of two parts: the antenna body and the outer casing. The size of the antenna body determines the minimum size of the outer casing. The key components of the antenna body are mainly the radiating element, the feed network, and the reflector. Typically, the radiating element is fixed to the front of the reflector, and the feed network is fixed to the back of the reflector. The shape and size of the radiating element and the reflector, as well as the distance from the front of the reflector to the antenna casing, are matched. The feed network mainly affects the distance from the back of the antenna reflector to the antenna casing, and has little impact on the width of the antenna reflector. Taking a single-row two-port antenna as an example, the radiating element is fixed horizontally and centered on the front of the reflector. The width of the reflector is 0.7-1.1 wavelengths of the center frequency of the operating band. For example, the reflector width of a 1710-2690MHz single-row two-port antenna is about 135mm, and the reflector width of a three-row six-port antenna is about 400mm. In summary, as the number of antenna arrays increases, the width of the reflector also increases, with some antennas even reaching 650mm in width. This leads to a significant decrease in reflector strength, causing connected components such as radiating elements, feed networks, and support plates to loosen, deform, or even detach. This results in a deterioration in the antenna's electrical performance, such as reduced consistency in standing wave isolation, worsened intermodulation, and decreased structural reliability. Moreover, the wider and longer the reflector, the more prone it is to deformation, making antenna assembly, debugging, and relocation more difficult. Simultaneously, with the increase in the number of antenna ports and the densification of the arrays, the mutual coupling between the antenna arrays becomes more complex, making it more difficult to achieve electrical performance independence for each antenna array.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] This invention provides an ultra-wide antenna reflector, including a main reflector assembly and a reinforcing device. The main reflector assembly includes a first component and a second component. The width of the first component and the second component is smaller than the total width of the main reflector assembly, thus reducing the degree of strength degradation of the main reflector assembly itself. The first component includes a first base plate, a first reinforcing side, and a first splicing side. The first base plate is fixed to the first component. The first reinforcing side and the first splicing side are disposed on both sides of the first base plate and form a certain angle with the first base plate, ensuring the strength of the first component itself. The second component includes a second base plate, a second reinforcing side, and a second splicing side. The second base plate is fixed to the second component. The second reinforcing side and the second splicing side are disposed on both sides of the first base plate and form a certain angle with the first base plate, ensuring the strength of the first component itself. The second component includes a second base plate, a second reinforcing side, and a second splicing side. The second base plate is fixed to the second component. The second base plate forms an angle with both sides of the second base plate, ensuring the strength of the second component. The reinforcing device includes reinforcing strips and fixed supports. The first base plate, the second base plate, the first splicing side, and the second splicing side integrate the first component and the second component with the reinforcing device. The reinforcing devices on the first and second base plates prevent misalignment and deformation of the first component, achieving structural reliability of the ultra-wide antenna reflector. Simultaneously, since the first and second components are separate, the current directions on their first and second splicing sides are opposite, creating electric field cancellation. This effectively reduces mutual coupling between the radiating elements of each array in the ultra-wide antenna, helping to maintain the consistency and independence of the electrical performance of each antenna array. Furthermore, in terms of manufacturing process, dividing an ultra-wide reflector into two components for separate assembly and then splicing reduces production difficulty, increases production efficiency, and saves production costs.

[0030] Therefore, the ultra-wide antenna reflector of the present invention meets the performance requirements of the antenna, reduces the difficulty of antenna production, and improves production efficiency.

[0031] Figure 1The diagram shows a conventional array layout for a 2-port antenna. The radiating element 2 is horizontally centered and fixed on the front of the reflector 1. The width of the reflector 1 is 0.7-1.1 wavelengths of the center frequency of the operating frequency band of the radiating element 2. The antenna's performance requirements can be met by using conventional support frames fixed between the front of the reflector 1 and the outer cover, and support plates fixed between the back of the reflector 1 and the outer cover.

[0032] Figure 2 The diagram shows a conventional array layout for a 12-port antenna. The reflector 1 includes a first base plate 11 and a second base plate 12, which are integrated. A low-frequency radiating element 21 is laterally fixed to the front of the first base plate 11, and similarly, a high-frequency radiating element 31 and a low-frequency radiating element 22 are laterally fixed to the front of the second base plate 12. Clearly, the increased number of elements in the transverse array leads to an increased width of the reflector 1, resulting in a significant decrease in its strength. Conventional methods are insufficient to meet the antenna's performance requirements.

[0033] Preferably, the first base plate and the second base plate, the first reinforcing side and the second reinforcing side, the first splicing side and the second splicing side are of the same or equivalent width, symmetrical sides, or equivalent side width, respectively.

[0034] Figure 3 This is a block diagram of the array layout of a 12-port antenna according to the first embodiment of the present invention. The reflector 1 includes a first base plate 11 and a second base plate 12. A low-frequency radiating element 21 is laterally fixed to the front of the first base plate 11, and a high-frequency radiating element 31 is also laterally fixed to the front of the first base plate 11. A low-frequency radiating element 22 is laterally fixed to the front of the second base plate 12, and a high-frequency radiating element 32 is also laterally fixed to the front of the second base plate 12. Moreover, the first base plate 11, the low-frequency radiating element 21, and the high-frequency radiating element 31 are symmetrically distributed with the second base plate 12, the low-frequency radiating element 22, and the high-frequency radiating element 32. Obviously, due to the increase in the number of horizontal arrays, the total width of the first base plate 11 and the second base plate 12 increases accordingly, and the width of the first base plate 11 and the second base plate 12 is half of their total width. The degree of deterioration in the strength of the reflector 1 itself is small, thus overcoming the antenna performance requirements in a conventional way.

[0035] Figure 4This is a block diagram of a conventional array layout for an 18-port ultrawide antenna. Low-frequency radiating element 2 is horizontally centered and fixed on the front of reflector 1. High-frequency radiating elements 31 and 32, and 33 and 34 are horizontally symmetrically fixed on the front of reflector 1, with elements 31 and 32 and 33 and 34 positioned vertically along the longitudinal direction of reflector 1. Clearly, due to the increase in the number of horizontal array elements, the width of reflector 1 increases accordingly, resulting in a significant decrease in the strength of reflector 1. Conventional methods are insufficient to meet the antenna's performance requirements.

[0036] Figures 5-10 This illustrates an 18-port ultrawide antenna according to a second embodiment of the present invention. Figure 5 The array layout diagram shows that the reflector 1 includes a first base plate 11 and a second base plate 12, which are joined together. Low-frequency radiating elements 2 are laterally fixed to the front of the first base plate 11, and high-frequency radiating elements 31 and 33 are laterally fixed to the front of the first base plate 11, respectively, and are placed vertically along the longitudinal direction of the first base plate 11. High-frequency radiating elements 32 and 34 are laterally fixed to the front of the second base plate 12, respectively, and are placed vertically along the longitudinal direction of the second base plate 12. Furthermore, the low-frequency radiating elements 2 are arranged laterally in the center of the total width of the first base plate 11 and the second base plate 12, and the high-frequency radiating elements 31 and 33, along with 32 and 34, are arranged laterally in the center of the total width of the first base plate 11 and the second base plate 12. Clearly, due to the increase in the number of horizontal array elements, the total width of the first base plate 11 and the second base plate 12 increases accordingly. Since the width of the first base plate 11 and the second base plate 12 is half the width of the reflector 1, the strength of the reflector 1 deteriorates only slightly, overcoming the antenna performance requirements in a conventional manner.

[0037] Preferably, the first base plate is perpendicular to the first reinforcing side and the first splicing side 111, and the second base plate is perpendicular to the second reinforcing side and the second splicing side 121. The first splicing side 111 is perpendicular to the second splicing side 121 and splices together, thereby realizing the assembly of the reflector 1 assembly.

[0038] Figure 6The diagram shows a front view of the reflector 1 of the 18-port ultrawide antenna. Clearly, the width of the first base plate 11 and the second base plate 12 is approximately half their combined width, resulting in minimal degradation of the reflector 1's strength. This overcomes the antenna's performance requirements using conventional methods. The first base plate 11 and the second base plate 12 are separate, and the radiating elements fixed to their respective front sides no longer share the same ground plane. This significantly reduces the mutual coupling between antenna arrays caused by a shared ground plane. Furthermore, since the currents on the first joining side 111 of the first base plate 11 and the second joining side 121 of the second base plate 12 flow in opposite directions, electric field cancellation occurs, effectively reducing mutual coupling between radiating elements, decreasing the abrupt changes in antenna array standing wave ratio and isolation, and improving the consistency and independence of the antenna array's electrical performance. In addition, by first assembling the first base plate 11 and the second base plate 12 separately and then assembling them, the assembly difficulty is significantly reduced, the space required for the assembly platform is decreased, production efficiency is improved, and production costs are saved.

[0039] Preferably, at least one of the aforementioned reinforcing devices is provided on the first base plate and the second base plate, the reinforcing device ensuring the strength of the reflector assembly and meeting the relevant performance requirements of the antenna.

[0040] Preferably, the reinforcing strip consists of a bottom and bent reinforcing edges on both sides of the bottom. The cross-section of the reinforcing strip is an open rectangle. The two sides of the reinforcing strip are fixed to the first base plate and the second base plate by fixing screws 6 in sections to ensure the strength of the reflector assembly.

[0041] Figure 7 The diagram shows a front view of the back of the reflector 1 of an 18-port ultrawide antenna. Reinforcing devices 41, 42, 43, and 44 are sequentially fixed longitudinally to the back of the first base plate 11 and the second base plate 12. With the assistance of the reinforcing devices 41, 42, 43, and 44, the strength of the reflector 1 formed by the first base plate 11 and the second base plate 12 is ensured, thereby meeting the relevant performance requirements of the antenna.

[0042] Preferably, the fixed support is connected to the first base plate and the second base plate on both sides, the top of the fixed support is connected to the bottom of the reinforcing strip, and the fixed support is convex in shape.

[0043] Preferably, an insulating gasket is provided between the first splicing side 111 and the second splicing side 121 to meet the structural reliability requirements.

[0044] Preferably, an insulating gasket is provided between the first base plate 11 and the fixed support, and an insulating gasket is provided between the second base plate 12 and the fixed support, so as to meet the structural reliability requirements.

[0045] Preferably, an insulating gasket is provided between the top of the fixed support and the bottom of the reinforcing strip to meet the structural reliability requirements.

[0046] Preferably, the first splicing side 111 and the second splicing side 121 are respectively provided with notches, the notches are used to avoid the reinforcing strip, and the reinforcing strip more firmly fixes the first base plate 11 and the second base plate 12.

[0047] Figure 8 The diagram shows a rear side view of the reflector 1 of the port ultrawide antenna 18. The first base plate of the first base plate 11 and the second base plate of the second base plate 12 are respectively fixed together with the same reinforcing device by multiple A structures. The reinforcing device includes 41, 42, 43 and 44. The first splicing side 111 of the first base plate 11 and the second splicing side 121 of the second base plate 12 are fixed together by multiple B structures. The first splicing side 111 of the first base plate 11 and the second splicing side 121 of the second base plate 12 are provided with notches to avoid the reinforcing strips 411, 421, 431 and 441 of the reinforcing devices 41, 42, 43 and 44. With the help of the reinforcing devices 41, 42, 43 and 44, the misalignment and deformation that may occur when the first base plate 11 and the second base plate 12 are spliced ​​are overcome, and the structural reliability of the ultra-wide antenna reflector 1 is realized. This avoids the problem that the reflector 1 is easy to deform due to poor strength, which may cause the connected radiating element, feed network and other components to become loose, deformed or even fall off, resulting in a deterioration of the antenna's electrical performance, such as poor consistency of standing wave and isolation, intermodulation deterioration, reduced structural reliability, and difficulties in antenna assembly, debugging and turnover. In this way, the electrical performance requirements of the antenna can be guaranteed.

[0048] Figure 9 The diagram shows the fixing of the reflector 1 and the reinforcing device of the 18-port ultrawide antenna. The first base plate 11 and the two sides of the fixing support 412 of the reinforcing device 41 are fixed together by screws 6, and an insulating gasket 7 is provided between their contact surfaces. Similarly, the reinforcing strip 411 of the reinforcing device 41 and the top of the fixing support 5 are fixed together by screws 6, and an insulating gasket 7 is provided between the contact surfaces of the reinforcing strip 411 and the fixing support 421. This design can meet both the structural reliability requirements and the electrical intermodulation requirements.

[0049] Figure 10 The diagram shows the fixing of the splicing side of the reflector 1 of the 18-port ultrawide antenna. The first splicing side 111 of the first base plate 11 and the second splicing side 121 of the second base plate 12 are fixed together by screws 6. An insulating gasket 7 is provided between the contact surfaces of the first splicing side 111 and the second splicing side 121. This design can meet both the structural reliability requirements and the electrical intermodulation requirements.

[0050] In summary, this invention provides an ultra-wide antenna reflector, including a main reflector assembly and reinforcing devices. The main reflector assembly includes a first component and a second component, both of which are narrower than the total width of the ultra-wide antenna reflector. The first component includes a first base plate, a first reinforcing side, and a first splicing side.
