Description

Technical Field

[0002] In recent years, communication technology has developed rapidly. As an important hardware component of communication technology, transceiver antennas have also made great progress. However, many deficiencies have emerged during the use of these antenna devices. For example, some antennas have large shapes and are not easy to move, but such antennas have strong adaptability. There are also some antennas with small shapes that can be flexibly moved, but such antennas often have poor adaptability. Once the usage environment changes, the coverage range of the antenna's capabilities is greatly reduced, resulting in its inability to be used and the need to replace it with an adaptable antenna. To address this problem, the usage scenarios of antennas in complex environments are analyzed, the typical application requirements in different scenarios are decomposed, and combined with the characteristics of the antennas in use, this application designs a brand-new miniaturized and quickly assembled test antenna. This antenna is small in size, flexible to move, and convenient to transport and move in different environments. Moreover, by using a multi-degree-of-freedom adjustment mechanism, the antenna overcomes the usage constraints in different environments, enhances the coverage application ability of the antenna, and solves the problem of poor adaptability of the same antenna in different environments, thus providing a brand-new, modular, and sustainable development idea for the subsequent development of small antenna technology.

[0031] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0032] As Figures 1 to 5 shown, a miniaturized and rapidly assembled test antenna, by analyzing the spatial movement trajectory of the antenna, decomposes the realization of the movement trajectory onto three movement module devices. And because the movement originally realized by one device is decomposed and realized by three modules, the design of each module is simplified, thus achieving the miniaturization and light weight of the module. Moreover, each module adopts the same interface design, enabling the entire inventive device to achieve a rapid assembly form during assembly. The following will introduce in detail the composition and the function of each part of the inventive device through specific examples, as follows:

[0033] Figure 1 and Figure 2 are the perspective view and the exploded view of a miniaturized and rapidly assembled test antenna according to the present invention. From Figure 1 and Figure 2It can be seen that the device is mainly realized by three parts, namely: a rotation module 1, a tracking module 2, and a multi-directional fine-tuning module 3. The connection relationship between the three modules is as follows: The rotation module 1 is at the bottom layer and is connected to the relevant fixed device. The tracking module 2 is installed on the rotation module 1, and the multi-directional fine-tuning module 3 is installed on the tracking module 2. The antenna 308 is installed on the tracking module 2 for use. The rotation module 1 is connected to the fixed device, providing support for the entire invention device and the rotation module 1 also has a one-dimensional rotational motion, which can provide a 360-degree rotational motion for the equipment installed on the rotation module 1. The tracking module 2 mainly designs a tracking device with two degrees of freedom of vertical rotational motion and left-right swinging motion based on the principle of the equatorial coordinate system. This device is mainly composed of two parts: the tracking mechanism main body 201 and the counterweight disk 202. The main function of the counterweight disk 202 is to balance the weight of the relevant equipment installed on the rotation module 1, so that the motion of the rotation module 1 is always in a balanced state. Figure 3 It is the internal structure diagram of the multi-directional fine-tuning module 3. The multi-directional fine-tuning module 3 can provide a 360-degree small swing motion, thereby providing a small-range fine-tuning motion for the antenna and helping the antenna to have higher positioning accuracy. The multi-directional fine-tuning module 3 is mainly composed of the following parts: a support barrel 301, an X-direction driving motor 302, a Y-direction driving motor 303, a Y-shaped fork rotating shaft 306, a central rotating ring 305, a large U-shaped rotating shaft 304, a linkage frame 307, and an antenna 308. The motion in the X direction is mainly realized by the X-direction driving motor 302, the Y-shaped fork rotating shaft 306, and the central rotating ring 305. The motion in the Y direction is mainly realized by the Y-direction driving motor 303, the large U-shaped rotating shaft 304, and the central rotating ring 305. The connection between the motion in the X direction and the motion in the Y direction is realized through the connection between the central rotating ring 305 and the linkage frame 307 to achieve the connection of the two motions. In actual motion, the motion in the X direction and the motion in the Y direction can both move independently, and at the same time, they can also perform linkage motion.

[0034] Figure 4 and Figure 5 It is the motion position diagram of a miniaturized and quickly assembled test antenna of the present invention. According to the motion characteristics of the device of the present invention, the motion diagrams of 2 positions are specially selected to illustrate the present invention, reflecting the design originality of the present invention and the coverage of the antenna space motion range.

[0035] The antenna involved in the present invention is small in external shape and volume, adopts a modular design concept, and has the ability to be quickly assembled and quickly tested in different environments.

[0036] The main purpose of a miniaturized and quickly assembled test antenna of the present invention is to meet the requirements in field tests. Compared with traditional test antennas, traditional ones are large in size and heavy in weight. Moreover, in a relatively poor field test environment, there are also great problems in installation and debugging. To solve this problem, the movement trajectory of the antenna with respect to spatial position changes is analyzed. Then, according to the design concept of sub-functional modules, the degrees of freedom of the antenna movement are determined in terms of position and function. A miniaturized and quickly assembled test antenna is designed. One advantage of this antenna is the sub-module design. The benefit of this design is that the antenna is divided into three modules, and each module is responsible for different movement functions, and the functions between modules do not interfere with each other. The second advantage is the miniaturized design. Since the sub-module design is adopted, the movement completed by one mechanism is decomposed and realized on three modules. Therefore, the design function of each module is simplified compared with the traditional antenna mechanism design. As a result, the function completed by each module is reduced. Subsequently, under the condition of meeting the function, each module adopts a miniaturized and lightweight design, increasing the flexibility of module use. The third advantage is the quick assembly property. When designing, a common interface is adopted between modules, which is easy to disassemble and assemble. During transportation, the modules are transported separately, and the transportation is flexible. When in use, because a unified interface is adopted between modules, they can be quickly assembled, making the antenna of the present invention have strong disassembly and assembly properties.

[0037] A miniaturized and quickly assembled test antenna of the present invention is mainly designed with three functional modules, namely a rotation module, a tracking module, and a multi-directional fine-tuning module. The rotation module mainly provides a one-dimensional rotation degree of freedom. The tracking module mainly adopts the method of astronomical observation and designs a tracking mechanism using the equatorial coordinate system. The multi-directional fine-tuning module mainly adopts a multi-joint mechanism design and can provide a 360-degree fine-tuning method. The entire mechanism is arranged in a line according to functional requirements. The rotation module is the basic module, with the tracking module connected above it, and the antenna is installed above the tracking module. Therefore, the antenna of the present invention has a large movement range in space, resulting in a strong coverage range of the antenna.

[0038] In addition, usually, when the antenna of the present invention is in use, the rotation module and the tracking module provide a large-range antenna movement tracking function, and the multi-directional fine-tuning module provides a small-range antenna fine-tuning function. Such a design can improve the tracking and positioning accuracy of the antenna during use and meet the high-precision use requirements of the antenna.

[0039] Considering the characteristics of a miniaturized and quickly assembled test antenna of the present invention, such as small size, flexible and compact, easy to carry and transport, and large antenna coverage range, the antenna of the present invention has strong adaptability in different environments. Therefore, when using the antenna of the present invention, multiple antennas are often used in an array.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
