Adopt planar & cylindrical near-field measurement to measure the antenna, in order to obtain the antenna's performance parameter

Working principle:
It adopts two test Ports of Vector Network Analyzer as the Input and output terminal of the
Near-Field measurement, Under the control of the host computer, meanwhile, through the
test probe on the scanner, output terminal transmits signals in a certain scanning mode
under the control of the driving device. At the same time, another port of tester collects test
data by using the antenna matrix and transfer the data to the master computer, then the
data processing system will analysis, diagnosis the Near-field characteristics of the
antenna matrix , and calculate the Far-field parameters. When perform cylindrical near-field measurement, the test antenna is mounted on the positioner, Under the control of the host computer, coordinate the positioner's rotating positioning, probe's scanning, and amplitude & phase data collection of the instruments. And then adopt cylindrical near-field data processing system to analysis, diagnosis the Near-field characteristics of the antenna matrix, and calculate the Far-field parameters .

System requires:
Working Frequency: 0.8~5GHz
Size of test antenna: 3.0m×0.35m
Effective scanning range: 4.5m×4.5m
Error of sidelobe measurement: <±1dB(-15dB,in sidelobe electric level)
Error of gain measurement: ≤ ± 0.5dB
Positioning accuracy: <±0.2mm

System Composition:
a) scanner
b) Positioner

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.
