Abstract

An octagonal split ring slot DGS (Defected Ground Structure) based MIMO (Multiple Input Multiple Output) microstrip antenna has been presented in this paper. Four ports rectangular patch elements, which are electrically small size 62.8 x 60 x 1.6 mm³ , with FR-4 substrate of dielectric constant 4.4 are proposed in the Multiple Input Multiple Output antenna. The ground plane, which is an inadequate ground structure (DGS) having a number of octagonal split ring slot DGS (OSRSDGS) windows are organised in H shape under the patch. The High-Frequency Structure Simulator (HFSS) software is used to simulate the MIMO antenna. The proposed antenna were simulated, fabricated, and measured. The proposed MIMO antenna resonates at 5.9 GHz frequency with -17.9 dB isolation with an overall bandwidth of 369 MHz. The proposed MIMO antenna results were explained in terms of reflection coefficients, data rate, Mutual Coupling Coefficients (MCC), and peak gain along with radiation pattern. The simulated and measured results give good agreement between them. The detail of the antenna design and results are presented and discussed.
