Abstract :
Indoor antenna measurements in classic anechoic chambers necessitate electromagnetic (EM) absorbers to cover the internal walls. An alternative fully metallic ellipsoid chamber structure is presented that controls the EM wave propagation to generate an appropriate quiet zone by guiding waves into a simple spherical absorber. The simulated performance demonstrates a significant reduction in absorber usage.
