Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to a multi-angle testing device for a satellite communication antenna. Background Art

[0002] An antenna is a transducer used for transmitting and receiving electromagnetic waves. It effectively radiates or receives electromagnetic waves in specific directions in space, enabling various functions such as wireless communication, positioning, and sensing. In modern society, antennas play a vital role in fields such as communications, healthcare, and transportation. For example, the antennas in mobile phone base stations are essential media for wireless communication and information exchange, supporting the operation and development of mobile communication networks.

[0003] In satellite communications, the satellite antenna serves as the intermediary between ground equipment and the satellite. Responsible for transmitting and receiving satellite signals, it is a critical component in ensuring the proper functioning of satellite communication systems. The performance of the satellite antenna directly impacts communication quality and stability, making precise positioning and adjustment of the antenna crucial during testing and calibration.

[0004] Traditionally, antenna mounting has relied primarily on manual bundling. Ensuring stable and precise positioning of antennas is crucial during antenna testing. However, traditional manual bundling methods exhibit significant shortcomings in this regard. Traditional methods often rely on manual attachment of antennas to test equipment or brackets, a process that can involve tying, bundling, and other complex operations. This method is inefficient, time-consuming, labor-intensive, and difficult to perform.

[0005] In this manner, the antenna may move or deviate during testing. Due to inadequate or inaccurate antenna mounting, it may shift slightly during testing, causing the antenna's pointing direction to deviate from its intended target. The quality of the antenna's received signal and the accuracy of its pointing direction are crucial to the test results. If the antenna moves during testing, test data may be skewed, affecting test accuracy. Such inaccurate test results can lead to subsequent performance issues in the communication system, such as signal degradation or unstable connections.

[0006] Furthermore, traditional fixing methods suffer from poor repeatability. Differences in manual operation can result in inconsistent fixing results each time the antenna is fixed. This variability can stem from a variety of factors, including operator experience, tooling, and operating environment. This inconsistency in fixing results directly impacts the comparability and consistency of antenna testing. Lack of comparability and consistency in test data can negatively impact antenna R&D, production, and quality control.

[0007] Comparability and consistency are key metrics for test data quality. Lack of consistent test conditions and results can make it impossible to reliably compare different antenna designs or production batches. This hinders antenna performance verification and optimization, quality control, and product improvement. Failure to ensure consistent test results during production can result in substandard products entering the market, impacting user experience and the overall reliability of communication systems.

[0008] In summary, traditional manual bundling methods present problems with antenna mounting, including low efficiency, complex operation, poor stability, and insufficient repeatability. These issues not only affect the accuracy of antenna testing but can also adversely impact antenna R&D, production, and quality control. Utility Model Content

To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0029] See also Figure 1 and Figure 2 A multi-angle testing device for a satellite communication antenna includes a test bench 1, an antenna fixing seat 2, an antenna support shaft seat 3 and an antenna angle adjustment positioning seat 4.

[0030] The test bench is formed into a base with a test surface on its upper portion. The antenna support shaft seat is fixed to the test surface of the test bench and has a rotating shaft. The antenna fixing seat is mounted on the antenna support shaft seat and tilts around the rotating shaft 2-1. The antenna fixing seat is equipped with a positioning pin. The antenna fixing seat is used to secure the antenna under test. The antenna angle adjustment positioning seat is provided with N positioning pin holes 4-1. The positioning pin holes are used to connect with positioning pins and are distributed along an arc centered on the rotating shaft.

[0031] In this embodiment, the test bench includes universal wheels 1-1, a support base 1-2, support legs 1-3, a push handle 1-4, a pull-out operating platform 1-5, a support crossbar 1-6 and a support table 1-7. The upper end surface of the support table forms the test table.

[0032] Specifically, the universal wheel is located below the support leg, and the universal wheel is tightly connected to the support leg through a connecting gasket and a fixing bolt. A locking mechanism is installed on the universal wheel, and the opening and closing of the universal wheel is controlled by the locking mechanism. The universal wheel is used to move the test device and adjust the angle direction of the antenna, and the test device can be fixed by a locking mechanism. The support legs are located around the support bottom, and the support legs are connected to the support base by welding. The support legs are also connected to the pull-out operating platform and the support table. The pull-out operating platform is connected to the support cross bars on all sides. The pull-out operating platform includes a slide rail and an operating surface. The slide rail of the pull-out operating platform is fixed to the support cross bar by bolts, and the operating surface slides through the slide rail. The push handle is fixed to the support leg, and the push handle is connected to the support leg by welding. The support table is at the top of the test device, and the support table is connected to the support legs shown by welding.

[0033] The support legs, support base, support crossbar, and support table are fixedly connected. The support legs are 80 cm high and ergonomically designed, allowing operators to perform antenna testing in a comfortable manner whether standing or sitting. The support base not only provides support, making the overall structure more stable, but also serves as a storage space for related test tools. The push handle is fixed to the support legs by welding, making it more portable and easier to control when moving the test device. The support crossbar and support legs are fixed by welding, which also serves to stabilize the structure. The two sides of the pull-out operating platform are installed on the support crossbar through slide rails. The slide rails use steel balls, which have a simple structure, save space, have a large load-bearing capacity, and are easy to replace. The pull-out operating platform 6 provides the operator with a host computer operating platform space for placing a PC notebook. The support table is used to connect the bottom components and the top antenna support structure, and is connected to the antenna angle adjustment positioning seat and the antenna support rod 1 with a fixed base through fixing bolts.

[0034] The antenna angle adjustment base is installed on the support table through fixing bolts and the fixing base. There are 10 openings on the antenna angle adjustment base as positioning pin holes, corresponding to 0° to 90°, with an adjustment positioning hole every 10°, which can more accurately control the azimuth direction.

[0035] The antenna mount includes an antenna support rod 3-1, an upper antenna support bracket 3-2, and a lower antenna support bracket 3-3. The lower end of the antenna support rod is attached to the rotating shaft of the antenna support shaft base. The antenna support rod mates with the antenna angle adjustment base via a positioning pin. The positioning pin and the pin hole engage to control the tilt of the antenna support rod and the antenna angle adjustment base, thereby controlling the tilt angle.

[0036] The upper antenna support bracket and the lower antenna support bracket serve as two points for supporting and fixing the antenna respectively. The upper antenna support bracket fixes the antenna under test 5 through a fixing buckle, and the lower antenna support bracket is fixed to the antenna under test through four fixing screws.

[0037] The lower antenna support bracket is connected to the antenna support pole through fixing bolts. The lower antenna support bracket is used to support the antenna and firmly fix the antenna to the antenna support pole by bundling. The upper antenna support bracket ties the antenna pole to the antenna support pole through the locking cap, which strengthens the fixation of the antenna and prevents the antenna from shaking during testing due to external factors such as natural weather, thereby affecting the antenna signal.

[0038] Furthermore, in this embodiment, the antenna angle adjustment positioning seat can be designed to be split, that is, a positioning arc plate is installed on it by bolts, and a positioning pin hole is provided on the positioning arc plate. The positioning arc plate serves as a positioning accessory of this device and can be replaced to adapt to the positioning angle requirements of different types of antennas.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
