Antenna Far-field Measurement Anechoic Chamber

Antenna Far-field Measurement Anechoic Chamber

Such anechoic chamber & related test field can fully the measurement on the radiation performance parameters, such as: Aantenna Gain, Radiation Pattern, Directivity, Axial Ratio, Half-power Beam width, Front to Back Ratio, Beam Pointing Angle, Cross-polarization Discrimination, Upper Side-Lobe Suppression, Zero-filling, Equivalent Radiation Efficiency and etc. EUT, e.g.: horn antenna, micro strip antenna, yagi uda, slot waveguide antenna and etc.

The test filed is a steel plate bolted anechoic chamber, with net size: 7m(L)×3m (W)×3m(H) (before the absorbers installed), and the distance between transmitting antenna and receiving antenna is 4m. Note: the size can be customized according to the users specific application and requirements.

This anechoic chamber with good ventilation, pollution-free, odor-free, can be monitored.

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.
