Designing A Metamaterial Inspired MIMO Antenna For Multi-Band Application

Abstract

creating a novel MIMO antenna with two elements that can operate in different bands. This study's design of an ultra-wideband and multiple band antenna was suggested along with an analysis of its characteristics. To accomplish the downsizing and performance of the two antennas, an isolation approach using well-designed metamaterials is proposed. The metamaterials employed significantly minimise the coupling of multi-antennas. Split-ring resonator (SRR) materials have been used to the antenna patch plane, which has improved the antenna's performance in terms of S parameters, multiplexing effectiveness, diversity gain (DG), radiation characteristics, and envelope correlation coefficient (ECC). To reduce the isolation between dual components, a novel decoupling structure has been studied and developed between the two antennas. The transmission rate is raised as a result. This antenna system has benefits including reduced weight and thickness, which makes it easier to integrate it into a receiver designed specifically for mobile communication. Using Computer Simulation Technology (CST), the antenna was tuned for 2-18 GHz with a permittivity of 2.2 and a thickness of 1.57 mm on a FR-4 substrate.
