Description

Technical Field

[0001] This utility model belongs to the field of mobile communication technology, specifically relating to a radiating component, an antenna configured with the radiating component, and a base station configured with the antenna. Background Technology

[0002] Driven by the current digital wave, the communications industry is booming, with various communication technologies constantly iterating and upgrading, placing more stringent demands on the performance and structure of communication infrastructure. To meet the needs of miniaturization and multi-band, multi-standard integration of base station antennas, and to improve space utilization, multi-band, multi-standard antennas generally adopt a coaxial nested structure. The core design idea of ​​this structure is to embed high-frequency radiating elements within low-frequency radiating elements. Through this spatial nesting layout, multi-band coverage of the antenna can be achieved within a limited space, thereby minimizing the antenna's size while ensuring its functionality. However, existing coaxial nested antenna structures have revealed a series of problems that urgently need to be addressed in practical applications.

[0003] First, bandwidth is a significant issue. Existing coaxial nested antenna structures have relatively narrow bandwidths, making them unsuitable for the application requirements of ultra-wideband (UWB). With the rapid development of communication technology, UWB has significant advantages in high-speed data transmission and high-capacity communication, but existing antenna structures cannot fully realize the potential of UWB, limiting the performance improvement and application expansion of communication systems.

[0004] Secondly, severe inter-band coupling occurs. Because high-frequency radiating elements are nested within low-frequency radiating elements, the electromagnetic field interaction between different frequency bands intensifies, leading to significant inter-band coupling. This inter-band coupling triggers a series of negative effects, the most prominent being decreased inter-band isolation. Poor inter-band isolation means that signals from different frequency bands are more prone to interference, reducing signal purity and thus affecting communication quality. Simultaneously, beam efficiency is significantly reduced due to inter-band coupling, causing distortion of the antenna's signal radiation pattern and a reduced signal coverage area, failing to meet the signal coverage requirements of practical communication scenarios.

[0005] Third, the problem of reflector coupling energy has not been effectively solved. While some technological innovations have been implemented to reduce spatial scattering coupling between high and low frequencies, the design of using a shared reflector for both frequencies means that the energy coupled through the reflector cannot be effectively reduced. Excessive reflector coupling energy further exacerbates inter-band interference, leading to unstable antenna performance and impacting the reliability and stability of the communication system. Utility Model Content

[0006] The primary objective of this invention is to solve at least one of the aforementioned problems by providing a radiating component, antenna, and base station.

[0007] To achieve the various objectives of this utility model, the following technical solution is adopted:

[0008] To achieve one of the objectives of this utility model, a radiating component is provided, comprising:

[0009] A high-frequency oscillator includes a high-frequency base and a high-frequency radiating arm supported on the high-frequency base, wherein the bottom surface of the high-frequency base protrudes downward to form an extension.

[0010] A low-frequency oscillator includes a low-frequency base and a low-frequency radiating arm supported on the low-frequency base. The low-frequency base has a through hole, and the bottom surface of the low-frequency base protrudes downward to form an annular support seat. The annular support seat and the through hole are coaxially arranged.

[0011] The high-frequency oscillator is nested within the low-frequency oscillator, and the extension passes through the through hole.

[0012] In one embodiment, the annular support base and the through hole are coaxially arranged, and the axial length of the annular support base is less than 0.05 times the operating frequency of the low-frequency oscillator.

[0013] In one embodiment, the annular support is formed by the outer edge of the low-frequency base or the outer edge of the through hole protruding downwards.

[0014] In one embodiment, a first connecting seat and a power supply hole are also formed on the bottom surface of the low-frequency base. The first connecting seat and the power supply hole extend in the same direction as the annular support seat. The first connecting seat is used to accommodate an external connector.

[0015] In one embodiment, the low-frequency oscillator includes a plurality of radiating components, each including a low-frequency radiating arm and a low-frequency balun. The two ends of the low-frequency balun are respectively connected to the low-frequency base and the low-frequency radiating arm. The plurality of radiating components are arranged sequentially along the circumference of the low-frequency base to form a mounting cavity, and the high-frequency oscillator is embedded in the mounting cavity.

[0016] In one embodiment, the low-frequency radiating arm includes a horizontal radiating stub arranged in a horizontal direction and a vertical radiating stub arranged in a vertical direction. The two ends of the horizontal radiating stub are respectively connected to the low-frequency balun and the vertical radiating stub, and the width of the horizontal radiating stub is greater than the width of the vertical radiating stub.

[0017] In one embodiment, the axial length of the extension is less than 0.05 times the operating frequency of the high-frequency oscillator.

[0018] In one embodiment, a second connector and a power supply channel are also formed on the bottom surface of the high-frequency base. The second connector, the power supply channel, and the extension extend in the same direction. The second connector is used to accommodate an external connector.

[0019] An antenna is provided to meet one of the purposes of this utility model, comprising a reflector and a plurality of radiating components as described in any one of the preceding purposes, wherein a low-frequency base of a low-frequency vibrator is situated on the reflector, a high-frequency base of a high-frequency vibrator is situated on the reflector, and the plurality of radiating components are arranged in an array.

[0020] To achieve one of the purposes of this utility model, a base station is provided, comprising the antenna as described in the preceding purpose.

[0021] Compared with the prior art, this utility model has many advantages, including but not limited to:

[0022] In the radiating assembly of this invention, the low-frequency vibrator rests on the reflector via a ring-shaped support, while the high-frequency vibrator rests on the reflector via an extension, thus increasing the distances between the low-frequency vibrator and the reflector, and between the high-frequency vibrator and the reflector, respectively. According to electromagnetic field theory, when the distance between the vibrator and the reflector increases, the current coupled to the reflector decreases significantly. Because current attenuates with increasing distance during transmission, increasing the distance reduces the electromagnetic interaction between the high- and low-frequency vibrators and the reflector, thereby effectively reducing the coupling degree between high and low frequencies. This significantly reduces signal interference when the antenna operates in different frequency bands, improving the antenna's anti-interference capability.

[0023] This invention's radiating component alters the antenna's resonant characteristics and expands its resonant frequency range by increasing the spacing between the low-frequency and high-frequency vibrators and the reflector. This is because the change in spacing affects the distribution of the electromagnetic field around the antenna, enabling it to effectively radiate and receive electromagnetic waves over a wider frequency range. By reducing the current coupled to the reflector, inter-band interference is reduced, resulting in more balanced antenna performance across all frequency bands. This expands the antenna's bandwidth, allowing it to meet the application requirements of ultra-wideband frequencies and providing communication systems with higher-speed, higher-capacity data transmission capabilities.

[0033] This invention provides a radiating component disposed on a reflector. By increasing the distance between the radiating component and the reflector, the bandwidth of the antenna is expanded, the coupling between the radiating component and the reflector is reduced, and the mutual coupling between high and low frequencies is reduced, thereby improving the communication performance of the antenna.

[0034] To clearly illustrate the structure and working principle of the radiating component in this utility model, the radiating component will be described below in conjunction with an antenna. However, this combination should not be regarded as a limitation on the scope of protection of this utility model.

[0035] In a typical embodiment of this utility model, combined with Figure 1 The antenna 100 includes a radiating component 200 and a reflector 300, with the radiating component 200 mounted on the front side of the reflector 300. The radiating component 200 includes a high-frequency vibrator 400 and a low-frequency vibrator 500, with the high-frequency vibrator 400 embedded within the low-frequency vibrator 500.

[0036] Combination Figures 2 to 4 The low-frequency oscillator 500 includes a low-frequency base 510 and a plurality of radiating components 520. The plurality of radiating components 520 are evenly distributed along the outer periphery of the low-frequency base 510. Through the cooperation of the low-frequency base 510 and the plurality of radiating components 520, they jointly form an installation cavity, which provides space for the installation of the high-frequency oscillator 400.

[0037] The radiating component 520 includes a balun (referred to as low-frequency balun 521) and a radiating arm (referred to as low-frequency radiating arm 522). Along the vertical direction of the low-frequency vibrator 500, the low-frequency radiating arm 522 is positioned above the low-frequency base 510, and both ends of the low-frequency balun 521 are connected to the low-frequency radiating arm 522 and the low-frequency base 510, respectively. In this embodiment, it is recommended that the length of the low-frequency balun 521 be set to 0.25 times the operating frequency of the low-frequency vibrator 500; however, this length setting is only a preferred option and should not be construed as a limitation on the scope of protection of this utility model.

[0038] In this embodiment, combined with Figure 4 The low-frequency radiating arm 522 is composed of two radiating branches. One radiating branch extends horizontally and is referred to as the horizontal radiating branch 5221 for ease of description; the other radiating branch extends vertically along the low-frequency vibrator 500 and is referred to as the vertical radiating branch 5222, and the vertical radiating branch 5222 extends toward the direction of the reflector 300.

[0039] The two ends of the horizontal radiating stub 5221 are connected to the low-frequency balun 521 and the vertical radiating stub 5222, respectively. Furthermore, the width of the horizontal radiating stub 5221 is greater than the width of the vertical radiating stub 5222. This width difference can alter the current distribution and radiation characteristics of the low-frequency vibrator 500, thereby effectively expanding the bandwidth of the low-frequency vibrator 500 and improving the radiation performance of the antenna 100, enabling it to maintain good radiation performance over a wider frequency range.

[0040] In a further embodiment, the horizontal radiating stub 5221 is divided into multiple radiating segments along its extension path. These radiating segments are further divided into wide radiating segments and narrow radiating segments, wherein the width of the wide radiating segment is greater than the width of the narrow radiating segment. The wide radiating segments and the narrow radiating segments are alternately arranged in the extension direction of the horizontal radiating stub 5221, which can further adjust the current distribution of the low-frequency vibrator 500, change its resonant characteristics, thereby further expanding the bandwidth of the low-frequency vibrator 500, optimizing the radiation performance of the antenna 100, and enabling the antenna 100 to achieve more efficient radiation at different frequencies, meeting the diverse performance requirements of the communication system for the antenna 100.

[0041] In a typical embodiment of this utility model, combined with Figures 2 to 4 The low-frequency base 510 has a through hole (referred to as the center hole 511), which extends through the low-frequency base 510 along the vertical direction. In this embodiment, it is recommended that the center hole 511 be located at the center of the low-frequency base 510, but this should not be construed as a limitation of the present invention.

[0042] The plurality of radiating components 520 are disposed on the top surface 512 of the low-frequency base 510 to achieve connection and fixation between the radiating components 520 and the low-frequency base 510. Meanwhile, an annular support 530 is disposed on the bottom surface 513 of the low-frequency base 510. The annular support 530 is annular in structure and protrudes downward along the vertical direction of the low-frequency base 510. Spatially, the annular support 530 protrudes towards the direction of the reflector 300.

[0043] Since the annular support 530 is an annular structure, a hole is naturally formed inside it, which is referred to as the annular hole 531 for ease of description. In this embodiment, the annular hole 531 and the central hole 511 are coaxially arranged, that is, their axes are located on the same straight line. This coaxial arrangement helps to ensure the symmetry and stability of the low-frequency base 510 structure. Furthermore, the diameter of the annular hole 531 is greater than or equal to the diameter of the central hole 511.

[0044] When the low-frequency vibrator 500 is mounted on the reflector 300, the annular support 530 sits on the reflector 300. Specifically, the low-frequency vibrator 500 is supported on the reflector 300 by the annular support 530, so that a certain gap is formed between the low-frequency vibrator 500 and the reflector 300, which can effectively increase the distance between the low-frequency base 510 of the low-frequency vibrator 500 and the reflector 300.

[0045] Increasing the distance between the low-frequency base 510 and the reflector 300 has significant positive effects. On the one hand, it effectively widens the bandwidth, enabling the low-frequency vibrator 500 to maintain good operating performance over a wider frequency range, meeting the needs of different communication scenarios. On the other hand, it improves the performance indicators of the antenna 100, such as its front-to-back ratio, cross-polarization, gain, and beam efficiency. Furthermore, increasing the distance reduces the coupling current between the low-frequency vibrator 500 and the reflector 300, thereby improving the isolation between high and low frequencies, reducing mutual interference between signals of different frequency bands, and ensuring the stability and reliability of the communication system.

[0046] In this embodiment, it is recommended that the extension length of the annular support 530 (i.e., the axial length of the annular support 530) be less than 0.05 times the operating frequency of the low-frequency oscillator 500. However, it should be clarified that this length setting is only a preferred option and should not be construed as a limitation on the scope of protection of this utility model.

[0047] In this embodiment, the outer edge of the bottom surface 513 of the low-frequency base 510 protrudes towards the direction of the reflector 300, thereby forming the annular support 530. Regarding the shape of the bottom surface 513 of the low-frequency base 510, in this embodiment, it is recommended to use any one of regular polygons such as circles, ellipses, and rectangles. However, it should be emphasized that the choice of the shape of the bottom surface 513 is only an exemplary design and should not be construed as a limitation on the scope of protection of this utility model. In practical applications, the shape of the bottom surface 513 of the low-frequency base 510 can be flexibly adjusted according to specific design requirements, spatial layout, and performance requirements.

[0048] To facilitate the explanation of the technical solution of this utility model, in this embodiment, the bottom surface 513 of the low-frequency base 510 is circular, and the cross-sectional shape of the annular support 530 is correspondingly circular, as an example for illustration. However, it should be clarified that this example should not be regarded as a limitation of this utility model, and other shapes of bottom surface 513 and annular support 530 are equally applicable to the technical concept of this utility model.

[0049] In another embodiment, the outer edge of the central hole 511 protrudes towards the reflector 300, thereby forming the annular support 530, which also provides support and spacing between the low-frequency vibrator 500 and the reflector 300. In this embodiment, it is recommended that the central hole 511 be a circular hole, and correspondingly, the cross-sectional shape of the annular support 530 is also circular. However, it should also be noted that the shape of the central hole 511 and the cross-sectional shape of the annular support 530 are only recommended designs and are not the only limitation of this utility model.

[0050] In another embodiment, the annular support 530 is disposed between the central hole 511 and the outer edge of the bottom surface 513 of the low-frequency base 510. In this embodiment, it is recommended that the cross-sectional shape of the annular support 530 be the same as the cross-sectional shape of the central hole 511 or the outer edge shape of the bottom surface 513 of the low-frequency base 510, which helps to ensure the symmetry and stability of the low-frequency base 510 structure. However, it should be emphasized that this shape matching relationship is only a recommended solution and should not be construed as a limitation of this utility model.

[0051] In one embodiment, a connecting seat (referred to as a first connecting seat 540) is further provided on the bottom surface 513 of the low-frequency base 510. The first connecting seat 540 is used to accommodate an external connecting member, through which the low-frequency base 510 and the reflector 300 are connected, so as to stably mount the low-frequency vibrator 500 on the reflector 300. In this embodiment, the external connecting member is a bolt, and the first connecting seat 540 is a screw hole seat, as an example to describe the present invention, but it should not be construed as a limitation of the present invention. The bolt threadedly connects the screw hole seat and the reflector 300 to stably fix the low-frequency vibrator 500 on the reflector 300.

[0052] In this embodiment, the first connecting seat 540 is disposed on one side of the annular support seat 530, or the first connecting seat 540 is disposed on the annular path of the annular support seat 530. The first connecting seat 540 and the annular support seat 530 extend the same distance toward the reflector 300 to facilitate the installation of external connectors onto the first connecting seat 540.

[0053] In one embodiment, the low-frequency base 510 is further provided with a power feeding hole 550, which penetrates the low-frequency base 510 in the vertical direction. A power feeding component (not shown) is provided in the power feeding hole 550. One end of the power feeding component is connected to an external power feeding device, and the other end of the power feeding component is electrically connected to the corresponding low-frequency radiating arm 522 through a cable 540 to power the corresponding low-frequency radiating arm 522.

[0054] In this embodiment, the power supply hole 550 is disposed on one side of the annular support 530, or the power supply hole 550 is disposed on the annular path of the annular support 530. The power supply hole 550 protrudes towards the reflector 300 relative to the bottom surface 513 of the low-frequency base 510 to facilitate electrical connection between the power supply component and an external power supply device. In this embodiment, it is recommended that the protruding length of the power supply hole 550 be the same as the extension length of the annular support 530, but this should not be construed as a limitation of the present invention.

[0055] In a typical embodiment of this utility model, combined with Figure 5 The high-frequency oscillator 400 includes a base (referred to as high-frequency base 410), two pairs of radiating arms (referred to as high-frequency radiating arms 420), and two baluns (referred to as high-frequency baluns 430). Each high-frequency balun 430 is connected to a corresponding high-frequency radiating arm 420, and the two high-frequency baluns 430 respectively support the two pairs of high-frequency radiating arms 420. In this embodiment, it is recommended that the pair of high-frequency radiating arms 420 form a dipole, but this should not be construed as a limitation of the present invention.

[0056] The high-frequency balun 430 has a top end and a bottom end at its two ends in the vertical direction. The top end of the high-frequency balun 430 is connected to a pair of corresponding high-frequency radiating arms 420, and the bottom end of the high-frequency balun 430 is connected to the top surface of the high-frequency base 410. In this embodiment, it is recommended that the length of the high-frequency balun 430 be 0.25 times the operating frequency of the high-frequency oscillator 400, but this should not be construed as a limitation of this utility model.

[0057] An extension 440 is formed on the bottom surface of the high-frequency base 410, and the extension 440 protrudes towards the reflector 300 along the vertical direction. When the high-frequency vibrator 400 is nested in the mounting cavity of the low-frequency vibrator 500, the extension 440 passes through the central hole 511 of the low-frequency base 510 of the low-frequency vibrator 500, so that the extension 440 sits on the reflector 300, that is, the high-frequency vibrator 400 sits on the reflector 300 via the extension 440. In this embodiment, the high-frequency base 410 and the extension 440 are integrally formed as an example to describe the present invention, but this should not be construed as a limitation of the present invention.

[0058] The extension portion 440 protrudes vertically toward the side where the reflector 300 is located. Its specific shape and size can be optimized according to actual design requirements to achieve good cooperation with the reflector 300 and other components. In this embodiment, it is recommended that the extension length of the extension portion 440, i.e., the axial length of the extension portion 440, be less than 0.05 times the operating frequency of the high-frequency vibrator 400, but this should not be construed as a limitation of this utility model.

[0059] When the high-frequency vibrator 400 is nested in the mounting cavity of the low-frequency vibrator 500, the extension 440 can pass through the central hole 511 of the low-frequency base 510 of the low-frequency vibrator 500, so that the bottom end of the extension 440 sits on the reflector 300. That is, the high-frequency vibrator 400 is connected and supported to the reflector 300 through the extension 440, so that the high-frequency vibrator 400 is stably set on the reflector 300.

[0060] The extension 440 plays a crucial supporting role in the connection structure between the high-frequency vibrator 400 and the reflector 300. It supports the high-frequency vibrator 400 on the reflector 300, thereby increasing the distance between the high-frequency base 410 of the high-frequency vibrator 400 and the reflector 300. This increased distance has several positive effects: firstly, it effectively widens the operating bandwidth of the high-frequency vibrator 400, enabling it to maintain good radiation performance over a wider frequency band; secondly, it improves the front-to-back ratio, cross-polarization, gain, and beam efficiency of the antenna 100, enhancing its overall performance; furthermore, it reduces the coupling current between the high-frequency vibrator 400 and the reflector 300, reducing mutual interference and improving the isolation between high and low frequencies, ensuring that the high and low frequency vibrators 500 can operate independently and stably.

[0061] In one embodiment, the extension 440 near the reflector 300 is further provided with a connecting seat (referred to as a second connecting seat, not shown). The second connecting seat is used to accommodate an external connector, which connects the extension 440 and the reflector 300 to stably mount the high-frequency vibrator 400 on the reflector 300. In this embodiment, the external connector is a bolt, and the second connecting seat is a threaded hole seat, as an example to describe the present invention, but this should not be construed as a limitation of the present invention. The bolt threadedly connects the threaded hole seat and the reflector 300 to stably fix the high-frequency vibrator 400 on the reflector 300.

[0062] In one embodiment, the high-frequency base 410 is further provided with a power supply channel 460, which passes through the high-frequency base 410 and the extension 440 in the vertical direction. A power supply piece (not shown) is provided in the power supply channel 460. One end of the power supply piece is connected to an external power supply device, and the other end of the power supply piece is electrically connected to a corresponding pair of high-frequency radiating arms 420 to power the corresponding pair of high-frequency radiating arms 420.

[0063] In a typical embodiment of this utility model, combined with Figure 1 The antenna 100 includes multiple radiating components 200, which share the same reflector 300 and are arranged in an array to facilitate the external radiation of signals and improve radiation performance.

[0064] This utility model also provides a base station, which includes the antenna described above.

[0065] In summary, the radiating component of this utility model increases the distance between the reflector and the low-frequency vibrator by setting an annular support base at the bottom of the low-frequency vibrator, and increases the distance between the high-frequency vibrator and the reflector by setting an extension at the bottom of the high-frequency vibrator, thereby reducing the mutual coupling between the low-frequency vibrator and the high-frequency vibrator and the reflector, improving the isolation between high and low frequencies, and optimizing the radiation performance of the antenna.
