Application Background

The antenna test rotator is a crucial equipment for the research and testing of communication antennas and radar antennas etc. It is used to measure the radiation characteristics of the antenna, such as the pattern, gain and polarization etc., ensuring antenna performance match the design demands.
In view of the high gain and narrow beam characteristics of phased array antennas, the antenna test rotator structure improved the concentricity and verticality of the azimuth axis, elevation axis and roll axis, matching the testing needs for performance verification, calibration and multi-beam testing of phased array antennas.

Technical Feature

1. Multi-axis structure: Antenna test rotator usually adopt multi-axis structures which can achieve multi-dimensional rotation and adjustment. This multi-axis structure can match various test demands of antenna, such as pattern, gain, axial ratio etc.

2. High-precision positioning and measurement: The positioning accuracy of the rotator is extremely high and the repeat positioning accuracy can reach ±0.005°.

3. Adaptable: The design of the rotator can accommodate antennas of different sizes and weights.

4. Automatic antenna clamping: The roll axis flange is equipped with an automatic antenna clamping mechanism. Once the antenna properly aligned, it can be clamped and fixed with the cable connection completed with one click.

Advantages

1.Improving accuracy: The high-precision positioning and measurement capabilities ensure accurate measurement of antenna performance parameters, reducing test errors. Via adopting high-precision transmission and control systems, the rotator can achieve precise angle adjustments and repeated positioning.

2.Enhancing flexibility: The rotator is suitable for diverse antennas test demands.

3.Automation and intelligence: The rotator connect to an upper-level automation control system, enabling remote operation and one-click automatic measurement.
