A Comprehensive Guide to RF Anechoic Chambers

RF Anechoic Chambers create a unique space for engineers and researchers to evaluate the performance of antennas, wireless devices, and electronic equipment.

The concept of an anechoic chamber originated in the early 1940s during World War 2. It was primarily driven by the need to test radar equipment without interference from reflections. Over the years, advancements in technology led to the development of RF Anechoic Chambers, which became crucial for various applications like electromagnetic compatibility testing, antenna testing, and RF measurements. These specialized chambers have the capability to remove external noise and reflection caused by electromagnetic waves.

If you’ve ever shouted ‘echo!’ in a large room, you’ve probably noticed some kind of reverberation and you’ve heard your voice repeat a few times. To avert this phenomena, anechoic chambers are lined on the inside with materials that are designed to completely absorb all sound waves therefore eliminating any and all reflections. With the presence of many sources of electromagnetic waves – ensuring electromagnetic compatibility is essential.
