Description

Technical Field

[0001] This disclosure relates to the field of mobile communication antenna technology, and in particular to an antenna. Background Technology

[0002] As a crucial component of mobile communications, antennas are generally designed to achieve low carbon emissions and high efficiency by reducing phase-shifting network losses and improving radiation efficiency.

[0003] The existing technical solution uses a network to eliminate cables, with direct feeding of the radiating element and phase-shifting network to reduce the transmission path. It also uses a metal air stripline instead of a printed circuit board (PCB) to reduce transmission line loss. This solution can effectively improve the antenna's gain, and eliminating cables allows for modular assembly of the vibrator and phase-shifting network, supporting automated installation. However, the phase from the phase-shifting network output port to the radiating element is fixed, which limits the antenna's radiation performance. Summary of the Invention

[0004] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides an antenna that can adjust the phase of the phase-shifting network and the radiating device, thereby achieving flexible and adjustable radiation performance.

[0005] This disclosure provides an antenna, including a phase-shifting network and a plurality of radiating devices mounted on the phase-shifting network;

[0006] The radiation device includes a dual-polarized oscillator, a metal cavity, and a feeding structure. The dual-polarized oscillator is disposed at the upper end of the metal cavity, and the feeding structure is disposed inside the metal cavity. The dual-polarized oscillator is fed to the output port in the phase-shifting network through the feeding structure.

[0007] The power supply structure is provided with a phase adjustment component, which is used to adjust the phase of the radiation device.

[0008] In some embodiments, the phase adjustment component is an insulating medium wrapped around the surface of the feed structure, and the length of the insulating medium is variable. By changing the length of the insulating medium, the phase of the radiation device is adjusted.

[0009] In some embodiments, the surface of the insulating medium is provided with a phase adjustment scale.

[0010] In some embodiments, the surface of the insulating medium is formed with tear-resistant grooves.

[0011] In some embodiments, the dual-polarized oscillator includes a first dipole and a second dipole arranged orthogonally, and the feeding structure includes a first feeding plate and a second feeding plate arranged orthogonally.

[0012] The first feed plate is electrically connected to the first dipole, and the second feed plate is electrically connected to the second dipole. The phase adjustment component is provided on both the first feed plate and the second feed plate.

[0013] In some embodiments, a through hole is formed in the metal cavity, the through hole penetrates the metal cavity, and the power supply structure is disposed in the through hole.

[0014] In some embodiments, the dual-polarized oscillator and the metal cavity are integrally formed.

[0015] In some embodiments, the phase-shifting network includes a reflector and a phase-shifting network cavity disposed on the bottom surface of the reflector. A signal transmission network is disposed within the phase-shifting network cavity, and the dual-polarized oscillator is fed to the output port of the signal transmission network through the feeding structure.

[0016] In some embodiments, an insulating sleeve is installed at the bottom of the radiating device, and the radiating device is limited and connected to the phase-shifting network through the insulating sleeve.

[0018] The antenna provided in this disclosure includes a phase-shifting network and multiple radiating devices mounted on the phase-shifting network.

[0026] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0028] like Figures 1 to 5 As shown, this embodiment of the present disclosure provides an antenna, including a phase-shifting network 2 and a plurality of radiating devices 1 mounted on the phase-shifting network 2. Each radiating device 1 includes a dual-polarized vibrator 11, a metal cavity 12, and a feeding structure 13. The dual-polarized vibrator 11 is disposed at the upper end of the metal cavity 12, and the feeding structure 13 is disposed inside the metal cavity 12. The dual-polarized vibrator 11 is fed to an output port within the phase-shifting network 2 via the feeding structure 13. A phase adjustment component is disposed on the feeding structure 13, and the phase adjustment component is used to adjust the phase of the radiating device 1.

[0029] The antenna provided in this embodiment can adjust the phase between the output port of the phase-shifting network and the radiating device by changing the setting of the phase adjustment component, thereby realizing the flexible adjustment of the antenna's radiation index. The phase adjustment components in each radiating device are independent of each other, so the phase of each radiating device can be adjusted independently.

[0030] In existing technologies, changes in the antenna array boundary cause variations in radiation performance, requiring the redesign of the phase-shifting network wiring, which is inflexible and costly. In contrast, the embodiments disclosed in this disclosure do not require redesigning the phase-shifting network wiring or adjusting the transmission lines of the phase-shifting network, thus achieving flexible optimization of the antenna's radiation performance at a low cost.

[0031] In some embodiments, the phase adjustment component is an insulating medium 130 wrapped around the surface of the feeding structure. The insulating medium 130 can be made of PE (polyethylene), PVC (polyvinyl chloride) or PP (polypropylene). The length of the insulating medium 130 is variable. By changing the length of the insulating medium 130, the phase of the radiation device 1 is adjusted. Figures 1 to 4 The diagrams show the state before the feed structure 13 is installed into the radiating device 1. By changing the length of the insulating medium 130, the dielectric constant of a portion of the transmission line in the feed structure 13 of the radiating device 1 can be altered, thereby adjusting the phase of each radiating device 1. When the phase of the radiating device 1 needs to be ahead, the insulating medium 130 is shortened to reduce the dielectric constant of the feed structure 13; when the phase of the radiating device 1 needs to be lagging, the insulating medium 130 is lengthened to increase the dielectric constant of the feed structure 13.

[0032] In some embodiments, an insulating sleeve 14 is installed at the bottom of the radiating device 1, and the radiating device 1 is mounted on the phase-shifting network 2 through the insulating sleeve 14. The bottom surface of the insulating sleeve 14 has a snap fastener, and the surface of the phase-shifting network 2 has corresponding mounting holes. The insulating sleeve 14 is connected to the phase-shifting network 2 by the snap fastener and mounting holes. The hollow portion inside the insulating sleeve 14 matches the size of the metal cavity 12 of the radiating device 1, allowing the radiating device 1 to be mounted on the phase-shifting network 2 through the insulating sleeve 14.

[0033] like Figure 5 As shown, in some embodiments, the phase-shifting network 2 includes a reflector 21 and a phase-shifting network cavity 22 disposed on the bottom surface of the reflector 21. A signal transmission network 23 is disposed inside the phase-shifting network cavity 22, and the dual-polarized oscillator is fed and connected to the output port of the signal transmission network 23 through the feeding structure 13.

[0034] The phase-shifting network cavity 22 is laid flat on the bottom surface of the reflector 21, making full use of the planar space of the reflector 21 and reducing the overall space occupied by the antenna. Figure 1 and Figure 2 As shown, ten radiating devices 1 are installed on the phase-shifting network 2, and the insulating medium 130 on the feed structure 13 of each radiating device 1 is set to a different length according to the actual phase adjustment needs.

[0035] In some embodiments, the bottom of the insulating sleeve 14 is provided with a power supply through hole, and the reflector 21 is also provided with a power supply through hole at the corresponding position. The power supply structure 13 is connected to the output port in the phase shifting network 2 through the power supply through holes of the insulating sleeve 14 and the reflector 21 to realize signal transmission.

[0036] like Figure 3 As shown, in some embodiments, the surface of the insulating medium 130 is provided with a phase adjustment scale, which shows the direct correspondence between the length of the insulating medium 130 and the phase of the radiating device 1. Typically, the initial length of the insulating medium 130 is relatively large, resulting in a large dielectric constant for the feed structure 13 and a significant phase lag for the radiating device 1. Each graduation of the phase adjustment scale represents the effect of shortening the insulating medium 130 to the current graduation on the phase of the radiating device 1. For example, the first graduation corresponds to a 1 / 4 wavelength lag, the second graduation corresponds to a 1 / 8 wavelength lag, the third graduation corresponds to no phase change, the fourth graduation corresponds to a 1 / 8 wavelength lead, and the fifth graduation corresponds to a 1 / 4 wavelength lead.

[0037] like Figure 4 As shown, in some embodiments, the surface of the insulating medium 130 is provided with easy-tear markings. These markings are formed circumferentially around the insulating medium 130, either once or halfway around it, to facilitate tearing off a specific length of the insulating medium 130 by tearing without the need to cut it with a tool. The easy-tear markings can also be combined with the aforementioned phase adjustment scale, forming easy-tear markings at the position of each scale line.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, the dual-polarized oscillator 11 includes a first dipole 111 and a second dipole 112 orthogonally arranged, with the two oscillators of the first dipole 111 and the two oscillators of the second dipole 112 orthogonally arranged to form a dual-polarized oscillator.

[0039] The power supply structure 13 includes a first power supply piece 131 and a second power supply piece 132 arranged orthogonally. The surfaces of the first power supply piece 131 and the second power supply piece 132 are both covered with an insulating medium 130 and are disposed inside the metal cavity 12. The upper end of the first power supply piece 131 is coupled and electrically connected to the first dipole 111, and the upper end of the second power supply piece 132 is coupled and electrically connected to the second dipole 112. The lower ends of the first power supply piece 131 and the second power supply piece 132 are connected to the output port in the phase shifting network 2 through the power supply through hole of the insulating sleeve 14 and the reflector 21.

[0040] In some embodiments, through holes 121 and 122 are formed within the metal cavity 12, penetrating the metal cavity 12, and the power supply structure 13 is disposed within the through holes 121 and 122. Specifically, a first power supply piece 131 is disposed within the through hole 121, and a second power supply piece 132 is disposed within the through hole 122. The diameters of the through holes 121 and 122 are slightly larger than the outer diameters of the first power supply piece 131 and the second power supply piece 132 (including the insulating medium 130), which can provide a relatively stable limiting effect on the first power supply piece 131 and the second power supply piece 132.

[0041] In some embodiments, the dual-polarized vibrator 11 and the metal cavity 12 are integrally formed, and the dual-polarized vibrator 11 and the metal cavity 12 can be manufactured simultaneously by die casting or sheet metal, thereby improving the production efficiency of the antenna.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0043] The above are merely specific embodiments of this disclosure, enabling those skilled in the art to understand or implement this disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to these embodiments, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
