MIMO Two Dimensional Metamaterial Antenna for Wireless Communication and Radar Applications

Abstract

The current research, aims in minimizing the mutual coupling between the antennas. An unique wideband square split ring metamaterial structure is proposed and positioned in the same plane of antenna. At frequencies between 4.2 GHz and 8 GHz, isolation of -20 dB is achieved due to the ENG features present in metamaterial structure. The metamaterial structure proposed has a permittivity of 4.3, it is made on FR-4 Substrate with 1.6 mm thickness. The proposed MIMO antenna operates in the C band (4.2 GHz-8 GHz) and has an isolation of -20 dB after applying a decoupling method in the entire C band. Gain, ECC, and DG among other performance and diversity factors, are computed and found within the allowed operating range for MIMO, further demonstrating that the design is a good substitution for the other existing design.
