A Practical Approach to Generating First-Order Rician Channel Statistics in a RC plus CATR Chamber at mmWave

Alejandro Antón Ruiz, Samar Hosseinzadegan, John Kvarnstrand +2

This paper explores a novel hybrid configuration integrating a Reverberation Chamber (RC) with a Compact Antenna Test Range (CATR) to achieve a controllable Rician K-factor. The fo…
