Abstract

A new sub-6 GHz antenna array that supports slant ±45. dual-polarization Multiple-Input-Multiple-Output (MIMO) communications with high inter-port isolation and stable radiation performance over wide scan angles and bandwidths is designed. An architecturally-inexpensive solution, which combines a standard truncated waveguide array and a single-layer patterned metasurface superstrate with wave manipulation capabilities, is proposed. A task-oriented formulation is adopted to mathematically formulate the EM associated multi-scale design problem, then solved with an innovative instance of the System-by-Design (SbD) paradigm where the fast and reliable modeling of the device is yielded by an ad-hoc artificial intelligence based surrogate. The final layout of the antenna array is validated with industry-standard full-wave numerical simulators.
