Abstract:
First realizations of reconfigurable intelligent surfaces (RIS) are becoming available as research on 6G advances. Consequently, prototypes have to be characterized by means of radiation pattern measurements to confirm the design properties. The main challenges here are the degrees of freedom from independent receiver and transmitter location in combination with surface configurations. We propose a far-field to near-field measurement setup to conduct first full-sphere CATR measurements of a 5 GHz RIS at RWTH Aachen University. In order to cope with parasitic effects of the near-field probe, applicable post-processing methods including time gating and reconstructed equivalent currents are applied and evaluted.
