Analyzing DGS behavior for a MIMO antenna system using theory of characteristic modes

In this paper, the Theory of characteristic modes (TCM) is used for analyzing the behavior of a defected ground structure (DGS) as an Isolation enhancement method for Multi-Input-Multi-Output (MIMO) antenna systems. For analysis purposes a MIMO antenna system consisting of PIFA elements is used. Modes of the antennas were analyzed and the modes contributing to coupling were blocked by the DGS. The other modes are not significantly affected by the addition of the DGS. Using this approach we were able to get 5 dB extra isolation in the Bandwidth of interest.
