| Custom Size Anechoic Chamber For EMI Testing |
A microwave anechoic chamber is a specially designed shielded space used for microwave and RF testing. By installing absorbing materials and shielding structures inside, it simulates a free-space electromagnetic environment, thereby avoiding external electromagnetic interference and eliminating internal electromagnetic wave reflections.

(a) Shielding Room:
The shielding room consists of a shielding shell, shielding door, ventilation waveguide window, and various power filters. The shielding shell can be either welded or assembled according to user requirements.(b) Absorbing Materials:
- Single-layer Ferrite Tiles: Operating frequency range 30MHz~1000MHz.
- Pyramid-shaped Carbon-loaded Foam Absorbing Material: This material is made by impregnating polyurethane foam in a carbon glue solution, featuring good flame retardancy
Antenna Testing:
- Far-field Testing: Used to measure the radiation characteristics and radiation pattern of antennas in the far-field region.
- Near-field Testing: Used to measure the performance parameters of antennas in the near-field region. Near-field measurement data can be used to calculate far-field radiation characteristics.
Electromagnetic Compatibility (EMC) Testing:
- Used to detect and evaluate the electromagnetic interference (EMI) and electromagnetic susceptibility (EMS) of electronic devices to ensure they comply with relevant EMC standards and regulations.
Radar Cross Section (RCS) Measurement:
- Used to measure the radar cross-section of objects, assessing their stealth characteristics in the radar band.
Radio Frequency (RF) and Microwave Device Testing:
- Used to test and calibrate various RF and microwave devices, such as filters, amplifiers, mixers, etc., ensuring their performance and parameters within specific frequency ranges.
Communication System Testing:
- Used to evaluate and verify the performance of communication systems, including signal propagation characteristics, antenna array performance, and signal coverage.
Material and Absorbing Material Testing:
- Used to test the performance of various absorbing materials and electromagnetic shielding materials, such as reflection loss and absorption coefficient, to evaluate their effectiveness in the microwave frequency range.
Education and Research:
- Used in universities and research institutions for teaching and research in related fields such as electromagnetic fields, antennas, wireless communication, and radar technology.
