Description

Technical Field

[0001] This utility model relates to the field of anechoic chamber technology, and more specifically, to a modular anechoic chamber. Background Technology

[0002] An anechoic chamber is a special type of shielded room primarily used to simulate open fields, and also for radiated radio interference (EMI) and radiated susceptibility (EMS) measurements. It consists of a shielded chamber and absorbing materials. The shielding effectively blocks interference from external electromagnetic signals, while the absorbing materials reduce internal reflections, thus creating a virtual infinite space within the chamber with virtually no internal reflections and minimal impact from unwanted external radio frequency noise.

[0003] The existing anechoic chambers are covered with absorbing materials on all six sides to simulate a completely free space environment. They are suitable for emission, sensitivity and immunity experiments. However, the absorbing material at the bottom is subject to excessive wear from long-term exposure to personnel, and replacement is difficult. Utility Model Content
