Abstract: We characterize three near-field sub-regions for phased array antennas by elaborating on the boundaries Fraunhofer, radial-focal, and non-radiating distances. The Fraunhofer distance which ...

Abstract: The natural integration of extremely large antenna arrays (ELAAs) and terahertz (THz) communications can potentially establish Tbps data links for 6G networks. However, due to the extremely ...
