Decoupling of Dual-Polarized Antenna Arrays Using Non-Resonant Metasurface
A non-resonant metasurface (NRMS) concept is reported in this paper to improve the isolation of dual-polarized and wideband large-scale antenna arrays. By properly designing the NRMS, it can perform stable negative permeability and positive permittivity ...
