Antenna Positioner

Antenna Positioner is a key part of antenna far-field measurement. Such 3-dimensional positioner system is composed by azimuth axis, pitching axis and polarization axis. Tested antenna is fixed on the installation surface of the polarization axis, and the positioner can accurately change the mechanical point of the antenna in space, in order to achieve the 3-dimentional direction pattern.

Technical Specification (Example)

The design ideas of such positioner are:

a) Positioner’s configuration: It adopts U-T framework structure, and the

framework is made up of welded steel plate components, which

ensure a sufficient strength and stiffness conditions of the components.

And it also greatly reduce the moment of inertia of the axises.

b) Dragging device: it adopts Japanese Yaskawa AC servo motor

c) Sensor: it adopts high-precision optical encoder as the angle sensor, in

order to achieve high-precision control of the positioner.

d) Control program: it adopts PC digital control to achieve full control function. The control system of the positioner contains a control PC, which is a direct control device of the positioner, to achieve high-precision and high frequency control requirements. The control PC, as a man-machine interface, adopts WINDOWS operation system, with a friendly interface, easy for operation and management.

We  mainly engaged in product R&D, system design and project contracting in the fields of Antenna measurement system and Anechoic Chambers as well as 5G telecom related testing and servies.

As a high-tech enterprise,we have been awarded a number of national high-grade qualifications, and has passed authentication of ISO9001 Quality Management System, ISO14001 Environmental Management System, and OHSAS 18001 Occupational Health and Safety Management System.

Due to excellent performance and good service, we have been one of the indispensable co-partner of the government, IT has undertaken and accomplished series of major projects in many significant missions including National-level Professional Anechoic Chambers, Largest Integrated Testing Anechoic Chamber in Asia and so on. Besides the outstanding achievement in China, we had exploited the international market actively and had exported the products to more than 80 countries and regions around the world. we also undertook some foreign aid projects from the Ministry of Commerce of the People-s Republic of China and achieved remarkable success.

We look forward to cooperating with the friends all over the world, making mutual benefit, and creating a bright future.
