Abstract
- This research work proposes a high gain MIMO antenna with improved isolation. The present antenna is low profile and contains four elements built with FR-4 substrate. This antenna uses a superstrate based metasurface to reduce the coupling between antenna elements and frequency selective surface (FSS) to improve the antenna gain. The suggested antenna is topped with a superstrate-based metasurface, which is positioned at a height of 15 mm below the antenna. FSS structure consists of a concentric circular ring on a single-layered FR4 substrate. The present MIMO antenna has operating band of 1.18–2.89 GHz with a peak gain of 8.44 dBi and isolation of less than − 20 dB between each antenna element. This MIMO antenna provides maximum efficiency of 96% and 92.3% reduction in the correlation coefficient. Additionally, the current structure offers a diversity gain (DG) of 9.99 and an envelope correlation coefficient (ECC) of 0.01. [ABSTRACT FROM AUTHOR]
