Description

Technical Field

[0001] This utility model relates to the field of communication vibrator equipment technology, and in particular to a mesh octagonal ultrawideband vibrator. Background Technology

[0002] FDD-LTE is a long-term evolution of communications, a global standard, and a trend in the development and evolution of communications. It improves and enhances air access technology for information, and has advantages such as high data transmission rate, packet transmission, low latency, wide coverage, and backward compatibility. However, since most existing FDD-LTE antenna elements have narrow bandwidth (790-870MHz / 806-960MHz), this narrow bandwidth is difficult to meet the current needs of communication base station construction, multi-system assembly, and signal coverage, and the cost is extremely high. Therefore, the development of FDD-LTE ultra-wideband dual-polarized antennas is the current focus of antenna research and development, and the development and optimization of FDD-LTE ultra-wideband dual-polarized elements, which are the basic units of FDD-LTE antenna arrays, are even more important.

[0003] In existing oscillators, the higher the frequency, the wider the frequency bandwidth. However, as the frequency decreases, the frequency bandwidth becomes narrower and narrower, making it impossible to achieve wideband and ultra-wideband in the low-frequency range, resulting in poor compatibility. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a mesh-shaped octagonal ultrawideband oscillator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mesh-like octagonal ultrawideband oscillator includes a support, a radiating metal plate arranged in an octagonal structure, and a feed plate. The radiating metal plate includes four radiating plates arranged at intervals along one end of the support. The area enclosed by the four radiating plates is coaxial with the support, and the feed plate is located within the area enclosed by the vertices of the four radiating plates. Each vertices of two adjacent radiating plates has a concave point, and each vertices of two adjacent radiating plates has a protruding convex point. The feed plate is coupled to two of the concave points and two of the protruding points. One end of the feed plate has a feed hole, and the other end has a cable core hole. The feed plate is electrically connected to the cable core and the feed post through the feed hole and the cable core hole.

[0007] By adopting the above technical solution, the radiating metal plate on the support is set into a diamond-shaped planar structure, enabling the vibrator to operate with a VSWR ≤ 1.4 within the frequency range of 680-960MHz. This allows for an antenna with a relatively uniform beamwidth within a 3dB width in the horizontal plane, achieving wideband and ultra-wideband capabilities in the low-frequency band, and providing stronger compatibility. The entire vibrator is small in size and low in profile, with stable structural performance and better consistency, meeting the needs of current mobile communication development.

[0008] Furthermore, the radiating sheet is provided with multiple sets of strip-shaped holes. Each set of strip-shaped holes includes multiple strip-shaped holes spaced apart along the apex of the radiating sheet towards the side away from the center of the support, and the strip-shaped holes are interconnected. The radiating sheet is provided with multiple strip-shaped holes, which reduces the size of the radiating metal plate, saves costs, and reduces the space occupied.

[0009] Furthermore, the radiating sheet is provided with four sets of strip-shaped holes. The size of the strip-shaped holes in the two middle sets of the strip-shaped holes is larger than that in the two sets of strip-shaped holes on the sides, and they are symmetrically arranged along the central axis of the radiating sheet. This can improve the symmetry and balance of the radiating metal plate, thereby further improving the isolation between the two polarizations.

[0010] Furthermore, the size of the strip holes in the same group of strip holes increases sequentially along the diameter direction of the radiating sheet, resulting in a compact structure and efficient use of space.

[0011] Furthermore, one end of the bracket is open, and a cavity is provided inside the bracket, which is connected to one end of the bracket; the other end of the bracket is sealed. Four through-slots are provided on the side wall of the cavity along its central axis to form four partition strips, and a radiating plate is fixedly connected to the end of each partition strip, making installation and disassembly more convenient.

[0012] Furthermore, each radiating plate has at least one extension post on its lower surface on the side away from the vertex, with the end of the extension post suspended away from the corresponding radiating plate. The extension post can optimize standing wave parameters, improve signal transmission efficiency and stability, reduce signal attenuation and distortion, and help maintain or expand the antenna's coverage area.

[0013] Furthermore, each of the radiating plates is provided with at least one reinforcing plate on the side facing the bracket. One side of the reinforcing plate is fixedly connected to the lower surface of the radiating plate, and the other side of the reinforcing plate is fixedly connected to the side of the bracket. The reinforcing plate can broaden the frequency band and improve the stability of the connection structure between the radiating metal plate and the bracket.

[0014] Furthermore, the vertices of any two adjacent radiating plates are perpendicularly arranged along the central axis of the diameter direction of the support, and the four radiating plates are arranged in a coplanar manner around the vertices, thereby improving the symmetry and balance of the radiating metal plate and improving the isolation between the two polarizations.

[0015] Furthermore, the bracket and the four radiating plates are integrally die-cast, resulting in an aesthetically pleasing appearance, small size, higher structural stability, easier processing, and lower cost.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] The radiating metal plate on the support in this invention is designed with a diamond-shaped planar structure, enabling the vibrator to operate with a VSWR ≤ 1.4 within the frequency range of 680-960MHz. This allows for an antenna with a relatively uniform beamwidth within a 3dB width in the horizontal plane, achieving wideband and ultra-wideband capabilities in the low-frequency band, and providing stronger compatibility. The entire vibrator is small in size and low in profile, exhibiting stable structural performance and better consistency, meeting the needs of current mobile communication development.

[0029] The following is in conjunction with the appendix Figures 1-6 The embodiments of this utility model will be described in further detail below.

[0030] A mesh-like octagonal ultrawideband oscillator 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a support 2, a radiating metal plate 3 with an octagonal structure, and a feed plate. The radiating metal plate 3 includes four radiating plates 31 arranged at intervals along the periphery of one end of the support 2. The area enclosed by the four radiating plates 31 is coaxially aligned with the support 2, and the feed plate is located within the area enclosed by the vertices 311 of the four radiating plates 31. Each vertices 311 of two adjacent radiating plates 31 have a concave point 32, and each vertices 311 of two adjacent radiating plates 31 have a protruding convex point 33. The feed plate is coupled to the two concave points 32 and the two protruding points 33. One end of the feed plate has a feed hole, and the other end has a cable core hole. The feed plate is electrically connected to the cable core and the feed post through the feed hole and the cable core hole. The structure of the feed plate is not shown in the figure.

[0031] The radiating metal plate 3 on the support 2 is designed with a diamond-shaped planar structure, enabling the vibrator to operate with a VSWR ≤ 1.4 within the frequency range of 680-960MHz. This allows for an antenna with a relatively uniform beamwidth within a 3dB width in the horizontal plane, achieving wideband and ultra-wideband capabilities in the low-frequency band, and providing stronger compatibility. The entire vibrator is small in size and low in profile, with stable structural performance and better consistency, meeting the needs of current mobile communication development.

[0032] In some embodiments, the four radiating plates 31 are arranged with identical structures, and the end face of the radiating plate 31 away from the vertex 311 is provided with three continuous fold lines. The fold lines of two adjacent radiating plates 31 are arranged correspondingly to make the radiating metal plate 3 present an octagonal structure.

[0033] Please refer to Figure 1 , Figure 3 The radiating sheet 31 is provided with multiple sets of strip-shaped holes. Each set of strip-shaped holes includes multiple strip-shaped holes 341 spaced apart along the apex 311 of the radiating sheet 31 towards the side away from the center of the support 2. The strip-shaped holes 341 are arranged through each other. The radiating sheet 31 is provided with multiple strip-shaped holes 341, which reduces the size of the radiating metal plate 3, saves costs, and reduces the space occupied.

[0034] Preferably, the radiating sheet 31 is provided with four sets of strip holes. The size of the strip holes 341 in the middle two sets of strip holes is larger than that in the two sets of strip holes on the sides. They are symmetrically arranged along the central axis of the radiating sheet 31, which can improve the symmetry and balance of the radiating metal plate 3, thereby further improving the isolation between the two polarizations.

[0035] Specifically, the dimensions of the strip holes 341 in the same group of strip holes increase sequentially along the diameter direction of the radiating plate 31, resulting in a compact structure and efficient use of space. Specifically, the strip holes 341 are designed with a fan-shaped structure, and both the arc length and the width along the diameter direction of the strip holes 341 increase sequentially.

[0036] In some embodiments, please refer to Figure 2 , Figure 4 The bracket 2 has one open end and a cavity 21 inside, which is electrically connected to one end of the bracket 2. The other end of the bracket 2 is sealed. Four through-slots 22 are provided on the side wall of the cavity 21 along its central axis to form four partition strips 23. Each partition strip 23 is fixedly connected to a radiating plate 31 at its end, which makes installation and disassembly more convenient and ensures that the spacing between adjacent radiating plates 31 is equal, thereby achieving impedance matching.

[0037] In some embodiments, please refer to Figure 3 , Figure 4The apexes 311 of the four radiating plates 31 are all located above the cavity 21. At least one extension post 35 is provided on the lower surface of each radiating plate 31 on the side away from the apex 311, with the end of the extension post 35 suspended away from the corresponding radiating plate 31. The extension post 35 can optimize the standing wave parameters, improve signal transmission efficiency and signal stability, reduce signal attenuation and distortion, and help maintain or expand the antenna's coverage. Specifically, in this embodiment, each radiating plate 31 is provided with two extension posts 35, and the spacing between adjacent extension posts 35 is the same.

[0038] Preferably, each radiating plate 31 has at least one reinforcing plate 36 on the side facing the support 2. One side of the reinforcing plate 36 is fixedly connected to the lower surface of the radiating plate 31, and the other side of the reinforcing plate 36 is fixedly connected to the side of the support 2. The reinforcing plate 36 can broaden the frequency band and improve the stability of the connection structure between the radiating metal plate 3 and the support 2. The end of the reinforcing plate 36 is fixedly connected to the side of the corresponding extension column 35, making the structure more stable.

[0039] In some embodiments, the apex 311 of any two adjacent radiating plates 31 is perpendicularly arranged along the central axis of the diameter direction of the support 2, and the four radiating plates 31 are arranged in a coplanar manner around the apex 311, which improves the symmetry and balance of the radiating metal plate 3 and improves the isolation between the two polarizations.

[0040] In some embodiments, the bracket 2 and the four radiating plates 31 are integrally die-cast, which is aesthetically pleasing, small in size, has higher structural performance stability, is easier to process, and has lower cost. It also helps to stabilize the vibrator and ensures the electrical performance of the antenna.

[0041] Please refer to Figure 5 , Figure 6 The direction can be seen from the directional diagram. Figure 1 Good consistency and relatively convergent. From the standing wave ratio (SWR) plots, we can see that: Trajectory 1 at 835.8MHz has an SWR of 1.3664 at port 1, indicating that the impedance matching of port 1 at this frequency is quite ideal (very little energy reflection); Trajectory 2 at 927.6MHz has an SWR of 1.3263 at port 2, indicating that the impedance matching of port 2 at this frequency is also very ideal; Trajectory 3 shows that when the signal is input from port 1 and output from port 2, the transmission loss is between -30dB and -40dB across the entire frequency band from 690MHz to 960MHz.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
