The anechoic chamber was built through carefully design and calculation, and it can provide near-field measurement conditions for testing antennas radiation performance. This chamber can effective eliminate outside electromagnetic interference and other reflection interference. It can simulate free space environment required by antenna measurement, in order to obtain reliable & standardized test data, ensuring the accuracy of antenna measurement.
According to the function, anechoic chamber’s main body can be divided into near-field antenna measurement microwave anechoic chamber and antenna measurement control room. Considering work type and usage, we would like to choose a rectangular anechoic chamber.
Anechoic chamber’s size: 60m×30m×30m (net size of shielding space)
Performance of absorbing materials:
Working frequency range 0.4～110GHz
Main wall’s reflection loss ≥35dB
Other wall’s reflection loss ≥30dB
Quiet zone’s reflection level:
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.
