[0033] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.

For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.

[0036] The terms used in the various embodiments of this application (such as "first," "second," etc.) may modify various constituent elements in the various embodiments, but do not limit the corresponding constituent elements. For example, the above terms do not limit the order and / or importance of the elements. The above terms are only used for the purpose of distinguishing one element from other elements. For example, a first user device and a second user device refer to different user devices, although both are user devices.

[0037] like Figure 1-6As shown, this application provides a helical antenna, including a base 3, a first carrier 1, and a second carrier 2. Both the first carrier 1 and the second carrier 2 are disposed on the base 3, and the second carrier 2 is located inside the first carrier 1. The first carrier 1 is provided with a plurality of spaced-apart first radiating arms 4, each extending from a first end to a second end of the first carrier 1. The second carrier 2 is provided with a plurality of spaced-apart second radiating arms 5, each extending from a first end to a second end of the second carrier 2. The extension direction of the second radiating arms 5 is different from that of the first radiating arms 4. The plurality of first radiating arms 4 and the plurality of second radiating arms 5 cooperate to realize multi-frequency communication, and the radiation patterns of different frequencies are different, thereby improving the flexibility of the device and optimizing the communication stability and reliability.

[0038] Specifically, this application achieves multi-frequency communication by nesting a first carrier 1, a second carrier 2, and radiating arms with different extension directions located on the first carrier 1 and the second carrier 2. It is compatible with multiple communication frequency bands, allowing the device to flexibly switch frequency bands without multiple antennas, thereby improving communication compatibility and versatility. Furthermore, by differentiating the radiation patterns of different frequency signals, it can adjust the radiation characteristics as needed, thereby greatly improving the flexibility of the device and optimizing communication stability and reliability.

[0039] like Figure 3-6 As shown, each first radiating arm 4 is rotated and tilted from the first end of the first carrier 1 to the second end of the first carrier 1 to form a first helical arm; each second radiating arm 5 is rotated and tilted from the first end of the second carrier 2 to the second end of the second carrier 2 to form a second helical arm; wherein the first and second helical arms are spatially intersecting. This application achieves a complex structural layout within a limited space by winding the first radiating arms 4 and the second radiating arms 5 into spatially intersecting first and second helical arms, respectively, significantly improving the utilization rate of the antenna's internal space. Furthermore, the spatially intersecting helical arm structure allows for flexible adjustment of the electrical length and radiation characteristics, easily enabling multi-frequency communication. Simultaneously, the intersecting helical arms form a unique radiation field, which can precisely control the signal patterns of different frequencies, thereby greatly improving the flexibility of the device and optimizing communication stability and reliability.

[0040] like Figure 3-6 As shown, the first radiating arm 4 or the second radiating arm 5 includes a meandering arm, a tapered arm, or a stepped arm. This application utilizes diverse structures such as meandering arms, tapered arms, or stepped arms in the first radiating arm 4 or the second radiating arm 5 to enable the antenna to achieve wider frequency band coverage and better performance in multi-frequency communication scenarios, thus adapting to complex communication environments.

[0041] Specifically, the curved arm precisely adapts to the low-frequency band by extending its electrical length, reducing antenna size while enhancing low-frequency gain; the gradient arm's smooth transition structure effectively widens the bandwidth, achieving seamless connection between adjacent frequency bands; the stepped arm flexibly adjusts the resonant frequency by varying its width to meet the performance requirements of specific frequency bands. Based on different performance requirements, the structural types of the first radiating arm 4 and the second radiating arm 5 are selected, thereby enabling the antenna to have wider frequency band coverage and better performance in multi-frequency communication scenarios, adapting to complex communication environments.

[0042] like Figure 3-6 As shown, the width of the first radiation arm 4 is the same as the width of the second radiation arm 5. This application uses the same width design to make the electrical characteristics of the first radiation suit and the second radiation arm 5 more consistent, which facilitates the coordinated control of radiation parameters to improve the quality of communication.

[0043] In this application, the number of first radiating arms 4 is the same as the number of second radiating arms 5. By using the same number of first radiating arms 4 and second radiating arms 5, this application achieves excellent frequency band coordination performance, efficient and smooth multi-frequency communication, and excellent anti-interference and gain, which greatly optimizes communication stability and reliability.

[0044] like Figure 3-6 As shown, the first carrier 1 includes a hollow cylindrical carrier or a hollow conical carrier; the second carrier 2 includes a hollow cylindrical carrier or a hollow conical carrier.

[0045] This application uses cylindrical and conical carriers, first carrier 1 and second carrier 2, to flexibly adjust the radiation mode according to different frequency band characteristics and communication needs. For example, cylindrical carriers are used to ensure coverage in low frequency bands, and conical carriers are used to improve gain in high frequency bands, so as to achieve optimal matching of multi-frequency band communication performance.

[0046] In one embodiment, the first carrier 1 includes a hollow cylindrical carrier, and the second carrier 2 also includes a hollow cylindrical carrier. The second carrier 2 is nested inside the first carrier 1. Through the cylindrical carrier structure design of the first carrier 1 and the second carrier 2, the radiating arms can be evenly spirally distributed along their surfaces to achieve a relatively stable and wide beam radiation pattern, which is beneficial for omnidirectional communication scenarios and ensures large-area coverage of signals in open environments.

[0047] In another embodiment, the second carrier 2 includes a hollow conical carrier and a centrally controlled conical narrow body. The conical carrier, due to its gradually changing shape, can change the helical curvature and spatial distribution of the radiating arms, forming radiation characteristics with directional gain, enhancing the signal strength in a specific direction, and is suitable for long-distance point-to-point communication.

[0048] like Figure 1-6As shown, the axis of the first carrier 1 and the axis of the second carrier 2 are on the same straight line. This application achieves high electromagnetic efficiency and optimized frequency band characteristics through the coaxial design of the first carrier 1 and the second carrier 2. At the same time, the coaxial design makes the overall antenna structure symmetrical and balanced, and significantly improves mechanical stability.

[0049] Both the first carrier 1 and the second carrier 2 include flexible carriers. This application greatly improves the flexibility of the first carrier 1 and the second carrier 2 by designing flexible materials.

[0050] like Figure 1-3 As shown, the base 3 includes a cover 31 and a base 32. The cover 31 is disposed on the base 32 and cooperates with the base 32 to define an accommodating cavity 7. The first carrier 1 and the second carrier 2 are located in the accommodating cavity 7. A connecting structure 8 is provided between the cover 31 and the base 32. The cover 31 is detachably connected to the base 32 through the connecting structure 8. This application uses the detachable design of the cover 31 and the base 32 to facilitate the quick separation of the cover 31 and the base 32, thereby facilitating the replacement and inspection of internal components such as the first carrier 1, the second carrier 2, and the radiation arms on the carriers, so as to improve the reliability and safety of the product.

[0051] like Figure 1-6 As shown, a bottom power supply plate 6 is provided on the base 32. The first carrier 1 and the second carrier 2 are set on the bottom power supply plate 6. The bottom power supply plate 6 is connected to the end of the first radiating arm 4 and the end of the second radiating arm 5, and is used to power the first radiating arm 4 and the second radiating arm 5. This application realizes multi-frequency communication through the cooperation between the first carrier 1, the second carrier 2, the bottom power supply plate 6, the first radiating arm 4 and the second radiating arm 5. It is compatible with multiple communication frequency bands, so that the device can flexibly switch frequency bands without multiple antennas, thereby improving communication compatibility and versatility.

[0052] The bottom power supply board 6 and the base 32 have a cavity 7, which is used to shield spatial interference signals and greatly improve the reliability of the equipment.

[0053] The bottom power supply board 6 is integrated with the first carrier 1 and the second carrier 2. The base 32 and the bottom power supply board 6 are detachably connected by screws 9. The detachable connection between the base 32 and the bottom power supply board 6 allows for better replacement of internal components and facilitates maintenance.
