Satellite Compact Antenna Test Range

Yice Technology's CATR can test products with a size of 0.6m. Its principle is to use a mirror to convert the spherical wave emitted by the feed source into a plane wave. It features a small testing distance, high accuracy, and small error. It can solve the problems of difficult alignment, poor confidentiality, and high climatic requirements in traditional far-field measurements. It is particularly suitable for the calibration test of satellite phased array antennas.

Anechoic Chamber Test

Yice Technology has built a standard 3-meter semi-anechoic chamber, which can be used for the radiation emission and radiation immunity tests of civilian products with a size of less than 2m. Its most prominent feature is that it does not rely on the main building at all. It is recommended to use it in an open area. The outer body of the darkroom is treated with special waterproof materials. It is completely possible to conduct normal tests under adverse weather conditions in the wild.

Antenna Calibration Open-Area Test Site

Yice Technology has built an OATS at its base in Chuzhou, Anhui Province, which is used for antenna calibration and metrology testing.
The core of the OATS is an elliptical flat area. Conductive metal plates are laid on the ground to suppress reflected interference. The antenna and EUT are respectively placed at the foci of the ellipse. The test distance is usually 3 meters, 10 meters or 30 meters. This site is mainly suitable for the 30MHz-1GHz frequency band. By scanning the antenna height (1-4 meters) and switching the polarization direction, the maximum superimposed field strength of the direct wave and the ground reflected wave is captured. This open field meets the requirements of low background noise and no reflectors, and can be widely used for electromagnetic compatibility radiation performance testing and antenna metrology calibration testing.

Automotive Antenna Open-Area Test Site

With the rapid development of automotive communication technology, the requirements for the performance of in-vehicle wireless communication are increasing day by day. As a core component of the entertainment system, the performance of the car radio antenna directly affects the reception effect and user experience of the entire system.
This test field focuses on the far-field performance testing of the vehicle's AM/FM/DAB antenna system, capable of measuring key parameters such as the pattern and antenna gain to comprehensively evaluate the vehicle's signal reception performance in all directions, thereby ensuring high-quality sound reception.
