Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna technology, specifically to a half-wave dipole antenna. Background Technology
[0002] In the field of 5G antennas, radiating elements (vibrators) are assembled on the feed network PCB board in an array manner. That is, the radiating elements are arrayed in the form of a certain row and column spacing and installed on the feed network PCB board.
[0003] For example, an SMT surface mount oscillator module structure, as disclosed in announcement number CN212412193U, includes a power supply network PCB board and oscillators. Multiple oscillators are arranged in an array on the power supply network PCB board. Each oscillator includes an integrally formed radiating surface and a power supply core. Four rectangular notches are formed by stamping a metal plate. The four rectangular notches are symmetrically distributed along the diagonal direction of the radiating surface. The metal sheet at the notch is bent downward to form the power supply core. The end of the power supply core is bent outward or inward at 90° to form the oscillator base. The width of the oscillator base is the same as the width of the power supply core. Corresponding pads are provided on the power supply network PCB board at the position of each oscillator base. The oscillators are directly surface mounted on the power supply network PCB board using an automated SMT surface mount process to form the final oscillator module structure.
[0004] Existing antennas all use the aforementioned PCBs or cables as transmission networks, which suffer from significant losses during transmission, resulting in insufficient gain and poor transmission efficiency. Utility Model Content

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] In a first aspect, this utility model provides a half-wave dipole antenna, comprising:
[0008] The reflector is provided with several spaced-apart network fixed protrusions;
[0009] The antenna feed network is fixed to each of the network fixing protrusions and suspended from the reflector.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0034] To address the technical problem of high network transmission loss in dipole antennas, this invention provides a half-wave dipole antenna that reduces network transmission loss and improves network transmission performance by forming an air microstrip.
[0035] like Figure 1-2As shown, the half-wave dipole antenna provided in this embodiment includes a reflector 10, an antenna feed network 20, a dipole module 30, and a dipole feed line 40. The reflector 10 is provided with a plurality of spaced-apart network fixing protrusions 11. The antenna feed network 20 is fixed to each network fixing protrusion 11 and suspended from the reflector 10, so that the antenna feed network 20 forms an air microstrip. The dipole module 30 is fixed to the reflector 10. The dipole feed line 40 is integrally formed on the antenna feed network 20 and connected to the dipole module 30. The dipole feed line 40 is coupled to the dipole module 30.
[0036] Specifically, the half-wave dipole antenna comprises a reflector 10, an antenna feed network 20, a dipole module 30, and a dipole feed line 40. The reflector 10 has several spaced-apart network fixing protrusions 11. The antenna feed network 20 is fixed to each network fixing protrusion 11 and is suspended from the reflector 10. The dipole module 30 is fixed to the reflector 10. The dipole feed line 40 is integrally formed with the antenna feed network 20 and connected to the dipole module 30, coupling with the dipole module 30 to form a network radiation structure. The integral forming of the dipole feed line 40 with the feed network eliminates the need for welding to connect the dipole feed line 40 to the antenna feed network 20, reducing the antenna welding process. Furthermore, since the antenna feed network 20 is suspended from the reflector 10, it forms an air microstrip, thereby reducing network transmission loss, increasing antenna gain, and enhancing antenna radiation efficiency.
[0037] In this embodiment, the antenna is completely solderless, reducing assembly steps, simplifying assembly, and avoiding a series of problems caused by poor soldering. This saves time and costs.
[0038] In one embodiment, the reflector 10 is made of die-cast plastic electroplating to reduce the weight of the antenna.
[0039] In one embodiment, the antenna feed network 20 is fabricated using metal cutting and stamping to enhance signal conductivity.
[0040] In this embodiment, each network fixed convex hull 11 is evenly spaced along the contour direction of the antenna feed network 20.
[0041] In one embodiment, such as Figure 1-3 As shown, the antenna feed network 20 is provided with several insertion holes at intervals, and the network fixing bulge 11 is provided with a limiting protrusion 111, which is inserted into the insertion hole. Specifically, the antenna feed network 20 can be limited on the reflector 10 by the limiting protrusion 111, and can be suspended by the support of the network fixing bulge 11, thereby forming a stable air microstrip.
[0042] In one embodiment, such as Figure 1-3As shown, the antenna feed network 20 is welded and fixed to the limiting protrusion 111. Specifically, after the antenna feed network 20 is installed on the limiting protrusion 111, it is then welded to the limiting protrusion 111 to achieve a stable connection.
[0043] In one embodiment, such as Figure 1-2 As shown in Figure 4, the vibrator module 30 includes a vibrator fixing member 31 and several vibrators 32. Each vibrator 32 is fixed to the reflector 10, and the vibrator fixing member 31 is connected to each vibrator 32. Specifically, the vibrator module 30 is fixed on the reflector 10 by fixing each vibrator 32 to the reflector 10. The vibrator fixing member 31 limits and stabilizes each vibrator 32 by connecting each vibrator 32, so that the vibrators 32 form a gap, effectively expanding the bandwidth of the antenna.
[0044] In this embodiment, there are 4 oscillators 32, and each oscillator 32 is a half-wave oscillator.
[0045] In one embodiment, such as Figure 1-2 As shown in Figure 4, the oscillator 32 includes an oscillator arm 321 and a radiating plate 322. The oscillator arm 321 is fixed to the oscillator fixing member 31, and the lower end of the oscillator arm 321 is fixed to the reflector plate 10. The radiating plate 322 is integrally formed on the upper end of the oscillator arm 321 and coupled to the oscillator feed line 40. Specifically, by integrally forming the oscillator arm 321 and the radiating plate 322, it is not necessary to further connect and fix the oscillator arm 321 and the radiating plate 322, thereby reducing the assembly difficulty of the oscillator module 30.
[0046] In one embodiment, such as Figure 1-2 As shown in Figure 4, a buckle 311 is provided on the top of the oscillator fixing member 31, and the buckle 311 is engaged with the radiation plate 322. Specifically, the radiating plate 322 can be stabilized by limiting the position of the buckle 311.
[0047] In one embodiment, such as Figure 1-2 As shown in Figures 4-5, the oscillator fixing member 31 is provided with a through-hole 312 with a side wall opening. The oscillator arm 321 passes through the oscillator fixing member 31 and is limited by the oscillator fixing member 31. Specifically, by providing the through-hole 312 with a side wall opening, when assembling the oscillator module 30, it is only necessary to first install the oscillator arm 321 into the through-hole 312 through the side opening, and then limit the radiating plate 322 by the buckle 311. This completes the assembly of the oscillator 32 and the oscillator fixing member 31, and achieves the stability of the oscillator 32 and the oscillator fixing member 31, reducing the assembly difficulty of the oscillator 32 and the oscillator fixing member 31.
[0048] In one embodiment, such as Figure 5As shown, the oscillator fixing member 31 is also provided with a lower opening for insertion into a cavity 313, into which the oscillator feed wire 40 is inserted. In this embodiment, when connecting the oscillator feed wire 40 to the oscillator module 30, it is only necessary to insert the oscillator feed wire 40 into the cavity 313 through the lower opening, thereby facilitating the assembly of the oscillator module 30 and the oscillator feed wire 40.
[0049] In this embodiment, the antenna feed network 20 can be assembled with the radiating part's vibrator module 30 first and then assembled onto the reflector 10, or it can be fixed onto the reflector 10 first and then the radiating part's vibrator module 30 can be installed. This simplifies assembly, reduces the types of parts, and improves assembly efficiency.
[0050] In one embodiment, such as Figure 1-2 As shown, the lower end of the vibrator arm 321 is fixed to the reflector plate 10 by rivets. Specifically, the lower end of the vibrator arm 321 is connected and fixed to the reflector plate 10 by rivets, thereby achieving welding-free fixing of the vibrator arm 321 and reducing the difficulty of fixing the vibrator arm 321.
[0051] In this embodiment, the vibrator arm 321 is fixed to the reflector plate 10 by rivets, so that the entire antenna assembly, except for the main feed welding of the antenna feed network 20, does not need to be welded, thus simplifying the assembly process.
[0052] In one embodiment, the vibrator fixing member 31 is a plastic part. Specifically, by making the vibrator fixing member 31 a plastic part, the production cost of the vibrator fixing member 31 can be effectively reduced, the weight of the antenna can be reduced, and the material cost of the antenna can be reduced.
[0053] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
