Acoustic Anechoic Chamber Antenna Testing Room With RF Absorber

Antenna test anechoic chamber with RF absorber

RF shielded room

The RF shielded room forms the basis for a semi-anechoic chamber. It’s a near RF-impenetrable metal box, that offers electric and magnetic field shielding effectiveness up to 100 dB over a wide range of frequencies. It’s good for emissions testing because no signals or ambient noise from the outside world can penetrate it, making it much easier to measure the emissions generated only by the EUT. It’s also good for immunity testing because no signals generated inside the enclosure can escape to the outside world, possibly causing harmful interference to equipment or personnel located nearby.

Keep in mind there are different types of shielding materials and configurations for semi-anechoic chambers and each of them have different shielding performance levels. If your application requires maximum shielding effectiveness, then you may want to consider shielding material that is double electrically isolated. This shielding has two layers of metal (one on the inner surface and one on the outer surface), typically connected at only the main grounding point of the chamber. If anything needs to be mounted to either the inside or outside of the chamber then the mounting screws selected should be keep short enough to penetrate just the first shielding layer and not go through the second.
