Description

Technical Field

[0001] This utility model belongs to the field of radar antenna technology, specifically, it relates to a quick-release triangular dipole antenna. Background Technology

[0002] With the rapid development of electronic technology, antennas are increasingly used in communication, direction finding and electronic countermeasures, which also puts forward higher requirements for their performance. They not only need to have characteristics such as wide bandwidth (often up to several times the frequency), small size, light weight and high strength, but also need to meet specific polarization methods, which undoubtedly increases the design difficulty of antennas.

[0003] Log-periodic antennas have been widely used in the aforementioned fields due to their significant advantages such as low cost, simple structure, light weight, and good consistency. Furthermore, research on reducing antenna size and improving structural strength by changing the shape of the elements, based on traditional log-periodic antennas, has become an important direction in the industry.

[0004] As an improved form, the triangular dipole element replaces the traditional dipole element, increasing the antenna's equivalent diameter and exhibiting excellent broadband performance. This ensures good matching of the antenna feed system across the entire frequency band and also improves the antenna's current distribution and gain, making it particularly suitable for log-periodic antennas. However, existing triangular dipole elements have certain limitations in practical applications. Their overall structure is often inconvenient for rapid setup and storage, and they occupy a large amount of space during packaging and transportation, making them unsuitable for portable use. Therefore, there is an urgent need for a triangular dipole element structure that allows for rapid assembly and disassembly and is easy to package and transport to solve these problems.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] As an example, see the attached document. Figure 1 As shown, in order to solve the above-mentioned technical problems, this embodiment provides a quick-release triangular dipole antenna, including a connecting line 1, at least one triangular dipole 2 and several linear dipoles 3;

[0031] One end of the linear oscillator 3 is fixedly connected to the connecting line 1;

[0032] As attached Figure 2 As shown, the triangular oscillator includes a first straight tube oscillator 201, a second straight tube oscillator 202, a bent tube oscillator 203, a mounting base 204, a pressure block 205, and a wing screw 206;

[0033] The two ends of the bent tube vibrator 203 are bent structures; one end of the first straight tube vibrator 201 is connected to one end of the bent tube vibrator 203, and the other end of the second straight tube vibrator 202 is connected to the other end of the bent tube vibrator 203.

[0034] The mounting bracket is set on the assembly line; see attached. Figure 3As shown, the pressure block 205 is disposed inside the mounting base 204; both the inner side of the mounting base 204 and the outer side of the pressure block 205 are provided with arc-shaped grooves; the arc-shaped groove on the outer side of the pressure block 205 and the arc-shaped groove on the inner side of the mounting base 204 form a gap; one end of the first bent tube vibrator 201 is disposed in the gap located on one side of the pressure block 205, and one end of the second bent tube vibrator 202 is disposed in the gap located on the other side of the pressure block 205.

[0035] The wing screw passes through the pressure block 205 and the mounting base 204 into the assembly line.

[0036] Optionally, the mounting base and pressure block are V-shaped clamping structures.

[0037] The V-shaped structure is more adaptable to the bending angle of the triangular oscillator, and can automatically align the connection ends of the first straight tube oscillator and the bent tube oscillator, as well as the second straight tube oscillator and the bent tube oscillator. This allows the gap formed by the arc groove to fit more tightly with the first straight tube oscillator and the second straight tube oscillator. This structure not only improves the uniformity of the clamping force and prevents the first straight tube oscillator and the second straight tube oscillator from loosening during use, but also simplifies the alignment operation during installation. Stable fixation can be achieved without precise adjustment of the oscillator position, further improving the efficiency of disassembly and assembly.

[0038] Optional, as shown in the appendix Figure 4 As shown, both ends of the bent tube vibrator 203 are provided with crimp nuts 2031; one end of the first straight tube vibrator is connected to one end of the bent tube vibrator and the other end of the second straight tube vibrator is connected to the bent tube vibrator by crimp nuts.

[0039] Crimped nut connections combine mechanical strength with electrical reliability: mechanically, they provide rigid fixation between oscillators, preventing loosening or detachment; electrically, the metal crimp nuts ensure low-impedance conduction between oscillators, reducing signal transmission loss. Furthermore, compared to non-removable connections like welding, crimped nuts allow for repeated assembly and disassembly without the need for special tools, offering quick-release advantages and facilitating maintenance and storage.

[0040] Optional, as shown in the appendix Figure 5 As shown, both the first and second straight tube vibrators include a straight tube 401, a crimping post 402, and a crimping screw post 403; one end of the crimping post 402 is provided with an external thread; one end of the straight tube 401 is provided with an internal thread; one end of the straight tube 401 is threadedly connected to the crimping post 402, and the other end of the straight tube 401 is connected to the crimping screw post 403.

[0041] The threaded connection between the straight tube and the crimping post allows for flexible adjustment of the overall length of the straight tube vibrator, adapting to different frequency band requirements and improving the antenna's versatility. The design of the crimping post and crimping screw post enhances the structural strength of the vibrator end, preventing deformation of the connection points due to frequent disassembly or external impact. The segmented structure combined with the threaded connection further reduces the packaging size (it can be disassembled for storage), and the tubular straight tube design maintains its lightweight advantage, enhancing portability. In addition, both the straight tube vibrator and the bent tube vibrator in this antenna are tubular structures, which reduces the overall size of the antenna.

[0042] Optionally, a spring-loaded washer is provided between the wing screw and the pressure block.

[0043] Spring-flat washer (a combination of spring washer and flat washer) can compensate for the loosening gap of wing screw through elastic deformation, prevent the screw from loosening due to external force during vibration, transportation or long-term use, and ensure the stable clamping force of the pressure block on the vibrator. At the same time, the flat washer can increase the force-bearing area, avoid the pressure block from deforming due to excessive local force, and extend the service life of the component.

[0044] Optionally, the linear vibrator includes an upper vibrator and a lower vibrator; the upper vibrator is positioned above the metal tube and one end is connected to the metal tube; the lower vibrator is positioned below the metal tube and one end is connected to the metal tube.

[0045] Vertically distributed linear dipoles can expand the radiating element distribution range of the antenna, optimize the current distribution, and thus broaden the operating frequency band and improve gain performance. In addition, the symmetrical vertical structure can enhance the antenna's balance, reduce the deformation of the metal tube caused by unilateral stress, and improve the overall structural stability.

[0046] Optionally, the center of the pressure block has a through hole structure; the through hole structure has an internal thread; the wing screw passes through the internal thread in the center of the pressure block.

[0047] The precise fit between the internal thread of the pressure block and the wing screw guides the screw to apply pressure vertically, preventing the pressure block from shifting under force and ensuring that the arc-shaped grooves on both sides of the pressure block fit evenly with the vibrator. This structure reduces local stress concentration in the vibrator, prevents the vibrator from bending due to long-term stress, and ensures the stability of the antenna shape.

[0048] Optionally, the mounting base has an internal thread at its bottom center; the wing screw passes through the internal thread at the bottom center of the mounting base.

[0049] The internal thread of the mounting bracket directly engages with the wing screw, which can directly transmit the screw's tightening force to the connecting line, forming a rigid force chain between the screw, pressure block, mounting bracket, and connecting line. This prevents relative slippage between the mounting bracket and the connecting line, further enhancing the connection stability between the triangular oscillator and the connecting line.

[0050] Optionally, the quick-release triangular oscillator of the antenna also includes a limiting box; the limiting box is provided with several through holes; each metal tube of the connecting wire passes through the through holes respectively.

[0051] The limiting box constrains the relative positions of the metal tubes in the assembly line through perforations, preventing the metal tubes from shifting, bending, or shaking due to external forces (such as collisions and wind) during transportation or use. The stable position of the metal tubes ensures that the relative arrangement of the linear and triangular dipoles remains unchanged, thereby maintaining the antenna's preset radiation performance (such as radiation pattern and impedance matching) and reducing performance fluctuations.

[0052] Each metal tube of the assembly line passes through the perforation of the limiting box, which can stabilize and fix each metal tube.

[0053] Optionally, the mounting bracket, pressure block, and wing screws are all metal components.

[0054] Metal materials have high strength and excellent conductivity: metal components can withstand greater clamping force and external impact, improving structural durability and adapting to complex environments such as outdoors and in the field; metal components can ensure the continuity of electrical connection between the triangular dipole and the connecting wire, reduce contact loss in signal transmission, and ensure the stability of the antenna's electrical performance (such as meeting the standards for VSWR and gain).

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
