Usage of Shaped Stubs for Mutual Coupling Reduction in A MIMO Antenna

Abstract

This paper discusses about the performance of a novel-shaped multi-input multi-output antenna (MIMO) which exhibits high-performance gain and low mutual coupling. The proposed design of the antenna is the introduction of radiating elements in the ground plane of the design, these radiating elements in turn help in producing high isolation between the MIMO antenna. The mentioned design of the antenna has a high diversity gain (DG>9.7) a very low mutual coupling (S21 < -60) an envelope correlation coefficient (ECC<0.07) and over the entire UWB frequencies high peak gains can be observed.
