Description

Technical Field

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

[0002] With the rapid development of the communications industry and the continuous innovation of industrial technology, base station antennas, as a key hub for information transmission, are facing unprecedented challenges and opportunities in their design and manufacturing. Against this backdrop, antenna technology is constantly evolving towards lightweighting, greening, and high performance to meet the increasingly stringent requirements of modern communication networks for energy efficiency, environmental protection, and deployment flexibility.

[0003] Among the many structural components of a base station antenna, the antenna vibrator plays a central role. It is not only a key element for electromagnetic wave radiation and reception, but also the most numerous component in the antenna structure. While traditional die-cast and sheet metal vibrators are widely used in the industry due to mature manufacturing processes and relatively low production costs, these metal vibrators generally suffer from inherent drawbacks such as significant weight. Furthermore, their radiating arms are prone to deformation during use, which not only increases the overall load on the antenna but also causes inconvenience in installation, transportation, and subsequent maintenance.

[0004] To address the issue of excessive weight of the oscillator making it difficult for traditional balun structures to effectively support the radiating arm, the industry has proposed using a plastic base to support the oscillator. However, existing plastic base structures have revealed significant limitations in practical applications, primarily in achieving stable fixation and reliable support for the radiating arm. This lack of secure fixation directly leads to fluctuations and degradation in the oscillator's electrical and radiation performance, compromising the stability and high quality of signal transmission.

[0005] Even more challenging is the structural stability of the oscillator, a persistent technical problem that the industry urgently needs to solve. This is especially true for oscillator structures with numerous slots in the radiating arms designed to optimize radiation performance; these slots significantly reduce mechanical strength, leading to insufficient structural rigidity. Such structures are highly susceptible to irreversible deformation during use. This deformation not only destroys the physical integrity of the oscillator but also severely interferes with its electromagnetic properties, thereby affecting the overall communication performance and coverage of the base station antenna.

[0006] Therefore, ensuring the stable support and structural stability of the oscillator radiating arm has become a technical bottleneck that urgently needs to be overcome by those skilled in the art. Summary of the Invention

The oscillator base includes an installation platform, the installation platform is configured with a limiting structure for the branch pair, the limiting structure includes a partition block embedded in the gap, and the limiting structure is configured with a fastener for at least one radial branch of the branch pair, the fastener being engaged with the corresponding radial branch.

[0009] In one embodiment, the limiting structure is that each of the two radial branches of the branch pair is equipped with a fastener.

[0010] In one embodiment, the partition block is disposed between the two fasteners, and the two fasteners are symmetrically arranged with respect to the gap of the corresponding branch pair.

[0011] In one embodiment, two branches are arranged to intersect, and the gaps between the two branches are connected to form a cross gap. A partition block is embedded in the cross gap, and the partition block is embedded in both gaps of the cross gap.

[0012] In one embodiment, the plurality of radiating branches include a plurality of main branches, the radiating section includes a radiating arm, the radiating arm being formed by connecting a power supply section to the plurality of main branches, the power supply section being used to receive external current to power the radiating arm to which it is located; at least one pair of branches has a gap extending to the power supply section, the mounting platform is provided with a fastening member corresponding to the power supply section, the fastening member is embedded in the gap extending to the power supply section, and the fastening member is engaged with the corresponding power supply section.

[0013] In one embodiment, the plurality of radiating branches further includes connecting branches. The radiating part includes a plurality of radiating arms. Two adjacent radiating arms with different polarization directions are connected by the connecting branches. The connecting branches and one main branch of each of the two radiating arms form the branch pair.

[0014] In one embodiment, the radiating part is integrally formed from sheet metal.

[0015] In one embodiment, the fastener includes a support plate protruding from the mounting platform, the support plate is provided with a snap-fit ​​spring, a snap-fit ​​groove is formed between the snap-fit ​​spring and the mounting platform, the radial branch is inserted into the snap-fit ​​groove, and the snap-fit ​​spring and the radial branch elastically abut against each other.

[0016] In one embodiment, the oscillator base further includes a support base, the mounting platform is disposed on the top of the support base, the support base has an installation channel, and the radiating unit further includes a feed plate, the feed plate is installed in the installation channel, and the feed plate is used to receive external current to feed the radiating part.

[0017] In one embodiment, the mounting channel is provided with a clamping structure corresponding to the power supply sheet. The clamping structure includes at least one pair of limiting blocks, each pair of limiting blocks being arranged opposite to each other and each pair of limiting blocks being located on both sides of the power supply sheet.

[0018] In one embodiment, the radiating part is further provided with a feeding arm, which is inserted into the mounting channel, and the feeding plate is coupled to or physically contacts the corresponding feeding arm to achieve electrical connection.

[0019] In one embodiment, a feeding slot is provided on the radiating part, and the feeding plate is inserted into the feeding slot. The feeding plate is coupled to or physically contacts the feeding slot to achieve electrical connection.

[0020] An antenna is provided to suit one of the purposes of the present invention, comprising a radiating element as described in any one of the preceding purposes.

[0021] To suit one of the purposes of this invention, a base station is provided comprising the antenna as described in the preceding purpose.

[0022] Compared with existing technologies, the present invention has many advantages, including but not limited to: First, this invention embeds a partition block in the gap between the branches and uses a fastener to secure the radiating branches. The partition block effectively maintains the distance between a pair of radiating branches, preventing them from approaching or even contacting each other due to local bending or external forces. Simultaneously, the fastener securely locks the radiating branches to the mounting platform. The combined effect of these two mechanisms significantly enhances the structural rigidity of the radiating branches and the entire radiating section, thereby preventing damage to physical integrity caused by structural deformation.

[0023] Secondly, this invention maintains the relative positions of the radiating branches through the separator blocks and provides a stable fastening force through the snap-fit ​​mechanism, ensuring that the current path flowing through the radiating branches remains constant. This robust mechanical constraint avoids poor contact or spacing changes caused by vibration or thermal expansion and contraction, thereby eliminating fluctuations in electrical performance and ensuring that the radiating unit can stably radiate signals to the outside according to predetermined radiation parameters.

[0024] Furthermore, this invention utilizes snap-fit ​​fasteners to securely fasten the radiating section to the mounting platform, achieving a quick and stable connection between the radiating section and the vibrator base. This mechanical connection method eliminates the need for additional fasteners (such as screws and nuts), simplifying the assembly process, reducing production costs, and avoiding potential failure risks caused by loose or detached fasteners. The snap-fit ​​fasteners and spacers work together to form multi-point limiting, effectively preventing displacement or rotation of the radiating section in any direction on the mounting platform, ensuring the structural integrity of the product during long-term use.

[0025] Furthermore, the combination of partition blocks and snap-fit ​​components allows for one-step installation and positioning of the radiating unit, significantly improving production assembly efficiency and product consistency. This modular installation method facilitates quality control and subsequent maintenance, while also creating favorable conditions for the miniaturization and high-density integration of the radiating unit.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0036] This invention provides a radiating unit. The radiating unit includes a mounting platform and a radiating section disposed on the mounting platform. The radiating section has a pair of branches, each pair consisting of a pair of radiating branches arranged side-by-side, with a gap between the branches. The mounting platform has a partition block embedded in the gap, and a fastening element is provided for at least one of the radiating branches in the pair. By engaging the corresponding radiating branches with the fastening element, the pair of branches is fixed to the mounting platform, thereby securely fixing the radiating section to the mounting platform.

[0037] In a typical embodiment of the present invention, combined with Figure 1 The radiation unit 10 includes a radiating section 100 and a oscillator base 200. The radiating section 100 is configured to receive an externally fed current signal and radiate electromagnetic wave signals outward under the excitation of the external current. The oscillator base 200 is provided with a mounting platform 210, on which the radiating section 100 is mounted and fixed. The mounting platform 210 provides stable mechanical support and positioning for the radiating section 100, effectively maintaining the overall structural stability of the radiating section 100, thereby ensuring that the radiating section 100 can continuously and stably radiate electromagnetic signals outward.

[0038] Specifically, combined Figure 2 The radiating section 100 includes a plurality of radiating branches 110. These radiating branches 110 are configured to conduct external current, allowing the external current to flow through them, thereby exciting the radiating section 100 to generate electromagnetic radiation. Simultaneously, by rationally setting the layout and size of the radiating branches 110, the radiating section 100 can radiate signals externally according to predetermined radiation parameters (such as radiation pattern, gain, etc.) to meet specific communication performance requirements.

[0039] Specifically, among the plurality of radial branches 110, a pair of radial branches 110 arranged side by side and adjacent to each other constitute a branch pair 120. In this branch pair 120, the two radial branches 110 are arranged at a distance from each other, thereby forming a gap 121 between them.

[0040] In one embodiment, the radiating part 100 is a sheet-like structure, and the radiating part 100 is integrally formed from sheet metal.

[0041] In a typical embodiment of the present invention, combined with Figure 3 The mounting platform 210 is provided with a mounting surface 211, and the radiating part 100 is disposed on the mounting surface 211. The mounting surface 211 is provided with at least one limiting structure 220 corresponding to each branch pair 120. The limiting structure 220 is used to fix the branch pair 120, so that the radiating part 100 can be stably disposed on the mounting platform 210, thereby maintaining the overall structural stability of the radiating part 100 and ensuring the stability of the external radiated signal of the radiating part 100.

[0042] Specifically, combined Figures 1 to 3 The limiting structure 220 includes a partition block 221 protruding from the mounting surface 211. The partition block 221 is embedded in the gap 121 of the branch pair 120 to separate the two radiating branches 110 in the branch pair 120. Through the limiting function of the partition block 221, the two radiating branches 110 can be effectively prevented from getting close to each other, avoiding contact caused by local bending deformation of the radiating branches 110, thereby maintaining the structural stability of the two radiating branches 110, ensuring the stability of the current flowing through the two radiating branches 110, and thus ensuring the stability of the electrical performance of the radiating part 100, so that the radiating part 100 can continuously and stably radiate signals to the outside.

[0043] In this embodiment, the width of the partition block 221 is equal to the width of the gap 121, or the width of the partition block 221 is slightly smaller than the width of the gap 121. This arrangement ensures that even if two radiating branches 110 tend to approach each other under external force, the partition block 221 prevents them from contacting each other, effectively maintaining the structural stability of the branch pair 120. This, in turn, guarantees the structural and electrical stability of the radiating section 100, ensuring the reliability of the radiating signal emitted by the radiating section 100.

[0044] The limiting structure 220 further includes a latching member 222 protruding from the mounting surface 211. The limiting structure 220 provides the latching member 222 for at least one radial branch 110 in the branch pair 120. The latching member 222 is used to engage with the corresponding radial branch 110, thereby firmly fixing the corresponding radial branch 110 to the mounting platform 210 to further maintain the overall structural stability of the radiating section 100.

[0045] In one embodiment, combined Figure 3 The latching member 222 includes a support plate 2221 and a snap-fit ​​spring piece 2222. The support plate 2221 protrudes from the mounting surface 211. The top end of the snap-fit ​​spring piece 2222 is connected to the support plate 2221, and the bottom end of the snap-fit ​​spring piece 2222 is opposite to and spaced from the mounting surface 211, forming a snap-fit ​​groove between the bottom end of the snap-fit ​​spring piece 2222 and the mounting surface 211. Figures 1 to 3 One section of the radial branch 110 extending axially (hereinafter referred to as the insertion section 111) is inserted into the snap-fit ​​groove. The bottom of the snap-fit ​​spring 2222 elastically abuts against the insertion section 111 to apply an elastic force to the insertion section 111, thereby fixing the insertion section 111 to the mounting surface 211. This achieves the fixation of the radial branch 110 to the mounting surface 211, and further, the fixation of the radial part 100 to the mounting surface 211.

[0046] In this embodiment, the snap-fit ​​spring piece 2222 is preferably integrally stamped from the support plate 2221 using a sheet metal process. The support plate 2221 has a notch formed due to the stamping process, and the snap-fit ​​spring piece 2222 hangs upside down at the notch. It should be noted that the specific forming process and structural form described above are merely illustrative and should not be construed as limiting the invention.

[0047] In one embodiment, the latching member 222 is disposed outside the gap 121 of the branch pair 120. Specifically, the latching member 222 is disposed on the latching side of the corresponding radial branch 110, the latching side and the gap 121 being located on opposite sides of the radial branch 110 in the width direction. The latching member 222 is located on the latching side of the radial branch 110 and latches with the corresponding insertion segment 111 from the latching side. Thus, even when the gap 121 of the branch pair 120 is small, the latching member 222 can still achieve effective latching on the latching side of the radial branch 110, and there is no need to manufacture the latching member 222 too small, thereby effectively reducing the manufacturing cost of the mounting platform 210.

[0048] In another embodiment, the latching member 222 may also be disposed within the gap 121. This allows the latching member 222 to be suitable for scenarios where the gap 121 is wide, or for situations where the latching member 222 and the partition block 221 are misaligned along the extension direction of the gap 121. It should be noted that the variations of the above embodiments are merely illustrative and should not be construed as limiting the invention.

[0049] In a typical embodiment of the present invention, the technical solution of the present invention is described in detail by taking the fastening member 222 disposed on the fastening side of the corresponding radial branch 110 as an example, but it should not be construed as a limitation of the present invention.

[0050] In this embodiment, combined with Figures 1 to 3 The installation platform 210 is equipped with a first limiting structure 230 for the branch pair 120. The first limiting structure 230 includes two latching members 222 and a partition block 221, wherein the partition block 221 is embedded in the gap 121 of the branch pair 120, and the two latching members 222 are respectively engaged with the two radial branches 110. In other words, the first limiting structure 230 provides one latching member 222 for each of the two radial branches 110.

[0051] Through the first limiting structure 230, the two fasteners 222 respectively fasten the two radiating branches 110, while the separator 221 is embedded in the gap 121 to separate the two radiating branches 110. Thus, under the constraint of the first limiting structure 230, the two radiating branches 110 can not only maintain their own structural stability, but also be firmly fixed on the mounting platform 210, thereby effectively maintaining the structural and electrical stability of the radiating part 100, and thus ensuring that the radiating unit 10 can stably radiate signals to the outside.

[0052] In a further embodiment, the two latching members 222 of the first limiting structure 230 are symmetrically arranged with respect to the gap 121 of the corresponding branch pairs 120. This symmetrical arrangement allows the two latching members 222 to apply symmetrical forces to the two radial branches 110, thereby ensuring a more secure connection between the two latching members 222 and the two radial branches 110, further enhancing the structural and electrical stability of the radial section 100.

[0053] In this embodiment, the partition block 221 is disposed between the two fasteners 222, and the partition block 221 and the two fasteners 222 are spatially collinear (i.e., all three are on the same straight line). Under the combined action of the partition block 221 and the two fasteners 222, the first limiting structure 230 can stably constrain and limit the branch pair 120, and firmly fix the branch pair 120 to the mounting platform 210. This layout effectively maintains the structural and electrical stability of the radiating part 100, thereby ensuring that the radiating unit 10 can continuously and stably radiate signals to the outside.

[0054] In one embodiment, the mounting platform 210 is further configured with a second limiting structure 240 for the branch pair 120. The second limiting structure 240 includes a latching member 222 and a partition block 221, wherein the partition block 221 is embedded in the gap 121 of the branch pair 120, and the latching member 222 is engaged with one of the radial branches 110 of the branch pair 120.

[0055] Through the second limiting structure 240, the fastener 222 engages with the corresponding radiating branch 110, thereby securely fixing the branch pair 120 to the mounting platform 210. Simultaneously, the separator 221 is embedded in the gap 121 to separate the two radiating branches 110. Thus, under the constraint of the second limiting structure 240, the two radiating branches 110 not only maintain their structural stability but are also securely fixed to the mounting platform 210, effectively maintaining the structural and electrical stability of the radiating section 100, thereby ensuring that the radiating unit 10 can stably radiate signals externally.

[0056] In one embodiment, the mounting platform 210 is equipped with both a first limiting structure 230 and a second limiting structure 240 for the branch pair 120. The first limiting structure 230 and the second limiting structure 240 are arranged sequentially along the extension path of the gap 121 of the branch pair 120. For example, the first limiting structure 230 and the second limiting structure 240 are respectively disposed at the beginning and end of the gap 121, which can provide double limiting for the branch pair 120 at both ends in the extension direction of the gap 121. Thus, not only is the branch pair 120 firmly fixed on the mounting platform 210, maintaining the structural stability of the branch pair 120, but also the structural and electrical stability of the radiating part 100 is effectively maintained, ultimately ensuring that the radiating unit 10 can stably radiate signals to the outside.

[0057] In one embodiment, combined Figures 1 to 3 The radiating section 100 includes two intersecting branch pairs 120, and the gaps 121 of the two branch pairs 120 are connected to form a cross gap. The mounting platform 210 is also equipped with a third limiting structure 250, which includes a partition block (hereinafter referred to as a cross block 251). The cross block 251 is respectively embedded in the two gaps 121 of the cross gap to maintain the structural stability of the cross gap.

[0058] Specifically, the two branch pairs 120 are a first branch pair 130 and a second branch pair 140, which are intersecting. The gap 121 of the first branch pair 130 is defined as the first gap 131, and the gap 121 of the second branch pair 140 is defined as the second gap 141. The first gap 131 and the second gap 141 are connected to form the intersecting gap. One of the first branch pair 130 and the second branch pair 140 is equipped with the third limiting structure 250, and the intersection block 251 of the third limiting structure 250 is simultaneously embedded in both the first gap 131 and the second gap 141. In this way, the structural stability of both the first gap 131 and the second gap 141 can be maintained simultaneously, thereby maintaining the structural stability of the first branch pair 130 and the second branch pair 140, ultimately ensuring the structural and electrical stability of the radiating part 100, enabling the radiating unit 10 to stably radiate signals externally.

[0059] In this embodiment, for ease of explanation, the example of the first branch pair 130 being configured with the third limiting structure 250 is used for illustration, but this should not be construed as a limitation of the present invention. In practical applications, the third limiting structure 250 may further include a fastening member 222, which is fastened and fixed to the radial branch 110 of the first branch pair 130.

[0060] In one embodiment, combined Figure 2 The radiating section 100 includes a radiating arm 150, which is composed of a feed section 151 and multiple main branches 152. Specifically, some of the radiating branches 110 of the radiating section 100 are the main branches 152, and the feed section 151 is connected to the multiple main branches 152 to jointly form the structure of the radiating arm 150. The feed section 151 is configured to receive externally fed current and transmit the current to the multiple main branches 152 to excite the radiating arm 150 to generate electromagnetic radiation, thereby realizing the function of external signal radiation. The main branches 152 are electrically connected to the feed section 151. The main branches 152 can effectively guide the distribution path of the current in the radiating arm 150, optimize the distribution characteristics of the electromagnetic field, and thus improve the radiation efficiency and signal radiation stability. This not only enhances the electrical performance of the radiating section 100 but also provides a structural basis for the radiation of multi-band or broadband signals.

[0061] In a further embodiment, the radiating arm 150 is provided with at least one third branch pair 160. The third branch pair 160 forms a gap 121 that extends to the feed section 151, and the feed section 151 constitutes the end of one end of the gap 121. Figures 1 to 3 The mounting platform 210 is provided with a fastening member 260 corresponding to the third branch pair 160. The fastening member 260 protrudes from the mounting surface 211 of the mounting platform 210. The fastening member 260 is embedded in the gap 121 of the third branch pair 160 and is located close to the power supply part 151. The fastening member 260 is fastened to the power supply part 151 to fix the power supply part 151 to the mounting platform 210. Through the fastening member 260, the overall structural stability of the radiating arm 150 can be effectively maintained, ensuring that the power supply part 151 can stably supply power to the radiating arm 150, thereby ensuring the structural and electrical stability of the radiating part 100.

[0062] In this embodiment, combined with Figure 3The fastening element 260 specifically includes a fastening spring 261. The bottom end of the fastening spring 261 is connected to the mounting platform 210, and the fastening spring 261 protrudes from the gap 121 of the third branch pair 160. The top end of the fastening spring 261 is bent towards the power supply part 151 and elastically abuts against the power supply part 151. The fastening spring 261 applies a stable elastic force to the power supply part 151, thereby firmly mounting the power supply part 151 on the mounting platform 210 and ensuring that the power supply part 151 can continuously and stably supply power to the radiation arm 150.

[0063] In another embodiment, combined Figures 1 to 3 The mounting platform 210 is further provided with a positioning pin 270 corresponding to the power supply unit 151. The positioning pin 270 protrudes from the mounting surface 211 of the mounting platform 210, and the power supply unit 151 has a matching positioning hole 1511. In the assembled state, the positioning pin 270 passes through the positioning hole 1511 to achieve relative positioning between the power supply unit 151 and the mounting platform 210, thereby driving the radiating arm 150 to be accurately installed on the mounting platform 210. Through the cooperation of the positioning pin 270 and the positioning hole 1511, the radiating arm 150 can be further structurally constrained, effectively limiting its displacement and sway on the mounting plane. This not only helps in the precise assembly of the radiating arm 150, but also ensures that the radiating arm 150 is stably set on the mounting platform 210, thereby significantly improving the overall structural stability and electrical reliability of the radiating unit 100.

[0064] In one embodiment, the radiating section 100 is configured with a plurality of polarizations, each polarization having at least one radiating arm 150. As a specific implementation, the radiating section 100 includes two pairs of radiating arms 150, and the polarization directions of the two pairs of radiating arms 150 are orthogonally arranged to each other.

[0065] Combination Figure 2In the plurality of radiating branches 110 of the radiating section 100, some radiating branches 110 are connecting branches 153. Two adjacent radiating arms 150 with different polarization directions are connected by the connecting branches 153. For ease of description, the two adjacent radiating arms 150 with different polarization directions are defined as a first radiating arm 170 and a second radiating arm 180, respectively. The first radiating arm 170 includes a first main branch 171, and the second radiating arm 180 includes a second main branch 181. The first main branch 171 and the second main branch 181 are arranged along the same axis. The connecting branch 153 is arranged side by side with both the first main branch 171 and the second main branch 181, that is, the connecting branch 153 forms a branch pair 120 with the first main branch 171 and the second main branch 181, respectively.

[0066] Furthermore, a third gap 172 is defined between the connecting branch 153 and the first main branch 171, and a fourth gap 182 is defined between the connecting branch 153 and the second main branch 181. The third gap 172 and the fourth gap 182 are arranged along the same axis and are interconnected to jointly form a fifth gap 121.

[0067] In this embodiment, combined with Figures 1 to 3 A limiting structure 220 is provided between the connecting branch 153 and the first main branch 171, and / or a limiting structure 220 is also provided between the connecting branch 153 and the second main branch 181. In another optional embodiment, the connecting branch 153, the first main branch 171, and the second main branch 181 share one or more limiting structures 220 to achieve effective positioning and constraint of adjacent radial arms 150.

[0068] In this embodiment, to clearly illustrate the technical solution of the present invention, the radiating section 100 is described as including two pairs of orthogonally polarized radiating arms 150. It should be noted that this is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0069] Specifically, combined Figure 2 In the arrangement of the two pairs of radiating arms 150, the radiating arm 150 of any polarization is arranged adjacent to the radiating arm 150 of the other polarization. For example, the two pairs of radiating arms 150 are defined as a first polarization and a second polarization, respectively, wherein the first polarization includes a first radiating arm 170, and the second polarization includes a second radiating arm 180 and a third radiating arm 190; the first radiating arm 170 is arranged adjacent to the second radiating arm 180 and the third radiating arm 190.

[0070] Furthermore, the end of the first radiating arm 170 away from the polarization center is connected to the end of the second radiating arm 180 away from the polarization center through a first connecting branch 183; at the same time, the end of the first radiating arm 170 away from the polarization center is connected to the end of the third radiating arm 190 away from the polarization center through a second connecting branch 191.

[0071] In a typical embodiment of the present invention, combined with Figure 3 The mounting platform 210 has a bottom surface and a mounting surface 211 disposed opposite to each other, wherein the mounting surface 211 constitutes the top surface of the mounting platform 210. The vibrator base 200 further includes a support base 280, the top of which is connected to the bottom surface of the mounting platform 210, and the support base 280 is used to provide structural support for the mounting platform 210.

[0072] The vibrator base 200 has an installation channel 290, which extends vertically and connects the installation platform 210 and the support base 280. Figure 4 The radiation unit 10 further includes a feed plate 300, which is installed in the mounting channel 290 and is used to provide a feed signal to one or more radiation arms 150 of corresponding polarization.

[0073] In this embodiment, the radiating arms 150 include two pairs of radiating arms 150 arranged orthogonally with polarization. The radiating unit 10 is independently configured with a feed plate 300 for each polarization, so that the two feed plates 300 respectively feed the two pairs of radiating arms 150.

[0074] In one embodiment, combined Figure 2 The power supply section 151 of the radiating arm 150 is provided with a power supply groove 1512. The power supply section 151 has a first surface facing the mounting surface 211 and a second surface opposite to the first surface and facing the same direction as the mounting surface 211. The power supply groove 1512 is recessed from the first surface toward the second surface.

[0075] Combination Figure 4 and Figure 2The top of the feed plate 300 is provided with a feed head 310, which is inserted into the feed slot 1512. The feed head 310 and the feed slot 1512 are fed through coupling, or the feed head 310 and the feed slot 1512 are in direct physical contact to achieve electrical connection; thus, after receiving external current, the feed plate 300 transmits the external current to the corresponding radiating arm 150. In this embodiment, the feed plate 300 is provided with two feed heads 310, which are correspondingly arranged with two radiating arms 150 of the same polarization, so that the feed plate 300 can simultaneously feed two radiating arms 150 of the same polarization.

[0076] In another embodiment, combined Figure 6 The radiating arm 150 has a feeding section 151 with a feeding arm 1513, which extends into the mounting channel 290. Figure 7 and Figure 5 The feeding arm 1513 is coupled to the feeding head 310 of the corresponding feeding plate 300, or the feeding arm 1513 is directly physically connected to the corresponding feeding head 310 to achieve electrical connection, so that the feeding plate 300 transmits the external current to the corresponding radiating arm 150 after receiving the external current. In this embodiment, the feeding plate 300 is provided with two feeding heads 310, which are correspondingly arranged with two radiating arms 150 of the same polarization, so that the feeding plate 300 can simultaneously feed two radiating arms 150 of the same polarization.

[0077] In a preferred embodiment, the power supply arm 1513 is integrally formed by stamping the power supply portion 151. It should be noted that this is only a preferred embodiment of the present invention and should not be construed as a limitation of the invention.

[0078] In one embodiment, combined Figure 1 The bottom end of the feed plate 300 is electrically connected to an external feed network, which supplies power to the radiating arm 150 via the feed plate 300. Specifically, the feed network is mounted on a terminal block 400, and the bottom end of the feed plate 300 is inserted into the terminal block 400, achieving electrical connection with the feed network on the terminal block 400. Furthermore, the bottom of the support base 280 is provided with a connecting structure, through which the support base 280 is connected to the terminal block 400, thereby ensuring that the feed network mounted on the terminal block 400 can stably supply power to the feed plate 300.

[0079] In one embodiment, combined Figure 3The mounting channel 290 of the vibrator base 200 is provided with a clamping structure corresponding to the feed plate 300. The clamping structure includes at least one pair of limiting blocks 291, each pair of limiting blocks 291 being arranged at a relative interval and located on both sides of the feed plate 300, to clamp and limit the feed plate 300, so that the feed plate 300 can be stably installed in the mounting channel 290, thereby ensuring that the feed plate 300 stably feeds the corresponding radiating arm 150, effectively improving the electrical stability of the radiating unit 10.

[0080] In this embodiment, the clamping structure is specifically configured with two pairs of limiting blocks 291. The two pairs of limiting blocks 291 are respectively disposed at both ends of the feed plate 300 in the width direction, and cooperate with each other to securely limit the feed plate 300 within the mounting channel 290, thereby further ensuring the power supply reliability and electrical performance stability of the radiation unit 10.

[0081] In one embodiment, the oscillator holder 200 adopts a one-piece molded structure and is made of insulating material, thereby effectively preventing the oscillator holder 200 from interfering with the electrical performance of the radiating section 100 and the feed plate 300. As a preferred embodiment, the oscillator holder 200 is made of plastic material. It should be noted that this is only a preferred embodiment of the present invention and should not be construed as a limitation of the present invention.

[0082] The present invention also provides an antenna comprising the radiating element 10 described above. Due to the use of the radiating element 10, the antenna maintains good structural stability and electrical performance, thereby achieving efficient signal radiation and reception.

[0083] The present invention also provides a base station, which includes the antenna described above. By configuring the antenna, the base station can provide stable and reliable wireless communication coverage, meeting the application requirements of communication networks.

[0084] In summary, the radiating unit of the present invention achieves both structural stability and performance optimization by mounting the radiating part on a mounting platform. Specifically, the radiating part has a pair of branches, and the mounting platform maintains the structural stability of the branch pair by embedding partition blocks in the gaps between the branch pairs and using fasteners to secure the radiating branches of the branch pairs. This firmly fixes the radiating part to the mounting platform, effectively ensuring the structural and electrical stability of the radiating part, thereby ensuring that the radiating part can stably radiate signals to the outside.
