A Super-Wideband and High Isolation MIMO Antenna System Using a Windmill-Shaped Decoupling Structure
In this paper, a novel super-wideband multiple-input multiple-output (SWB-MIMO) antenna system with high isolation has been proposed, each antenna element consisting of a spade-shaped radiation patch, a defected ground structure (DGS) as well as a windmill-shaped decoupling structure.The elliptical slot etched on the radiation patch and the rectang
