Four‐Port Metasurface‐Loaded Graphene–Ceramic THz Radiator With Frequency Tunability, Circular Polarization, and Enhanced Far‐Field Decorrelation
In this paper, a four‐terminal graphene‐coated ceramic antenna with a metasurface wall is proposed for tunable terahertz (THz) MIMO communication. The proposed design solves the problems of frequency reconfigurability, circular polarization, high port isolation, and better far‐field decorrelation in a compact archite...
