Effect of DGS Technique in MIMO Antenna
In this paper, the authors use DGS (Defective Ground Surface) in MIMO (Multiple-Input and Multiple-Output) antenna to enhance the antenna performance parameter. The concept of DGS with MIMO antenna reduces antenna size and reduce mutual coupling between the antenna elements. It also enhances parameters such as gain, directivity, return loss and efficiency. The MIMO antenna has two symmetric monopole, one metal strip, one triangle and two novels bent slits. In this paper, double E shaped DGS connected to each other are etched in the ground plane. The analysis has been done by using IE3D software based on Method Of Moments (MOMs).
