Description

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.

Antenna Far-field Measurement Anechoic Chamber

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.

① Anechoic chambe’s size: 7m(L)×3m(W)×3m(H) example size

② Working frequency: 0.5～10GHz

③ Quiet zones location: its center is 2m far from the back wall,and in the middle between up and down, left and right wall.

④ Quiet zones size:0.4m×0.4m×0.4m, and meet the far-field conditons

⑤ Quiet zones reflection level: 0.8～1GHz, >-25dB; 1～2GHz,>-30dB; 2～6GHz,>-35dB.

⑥ Cross polarization level ≤-25dB@1～10GHz

⑦ Shielding effectiveness: ≥80dB@0.8～10GHz

⑧ EUT (Antenna under test):

Frequency range: 0.5～10GHz

Antenna size: it should meet the far-field conditons

Gross weight ≤10kg

Test accuracy: Gain ≤ ±0.5dB

Side lobe (-10dB) ≤ ±1.0dB

3dB beamwidth measurement error ≤ ±5% of BW

Front to back ratio accuracy < 3dB

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