摘要

This communication proposes a novel decoupling approach for multiple-input multiple-output (MIMO) dielectric resonator antennas (DRAs) using a dielectric superstrate above the array. Utilizing the interaction with electromagnetic fields, the superstrate affects the coupled field distributions inside the adjacent DRA and so reduces coupling between two closely located DRAs. Five decoupling cases ar...
