K−factor Emulation in Different OTA Chambers

This paper discusses over-the-air testing chambers and the principles behind emulating Rician-distributed channel fading envelopes of the propagation channel. The discussed chambers are the classical reverberation chamber, the vibrating intrinsic reverberation chamber, the multi-probe anechoic chamber, the resonating cavity hybrid anechoic-reverberation chamber, and the aveguide hybrid anechoic-reverberation chamber.
