THz Plasmonic Metamaterial Antenna with High Isolation and Geometrical Performance Optimization for 6G/TWPAN Applications

The need for faster communication in today's world has led to the need for antennas with high bandwidth and gain. A novel THz MIMO antenna based on metamaterial is presented in this manuscript for high-speed communication applications with broad bandwidth and high gain. The THz MIMO metamaterial antenna is designed using a C-shaped metamaterial resonator. The metamaterial antenna is also compared with a simple square patch MIMO antenna design for different antenna parameters like gain, reflection, and transmission coefficients. The metamaterial MIMO antenna gives a higher bandwidth of around 1.95 THz, three operating bands and a maximum isolation of about 80 dB. The maximum gain of the metamaterial MIMO design is 20.4 dB. The metamaterial MIMO antenna is also optimized for its geometrical parameters like slot length, slot width, substrate thickness and ground layer thickness. The optimized value of slot length, slot width, substrate and ground layer thicknesses are obtained as 10 mu m, 10 mu m, 1.5 mu m and 1 mu m, respectively. The MIMO parameters like ECC, DG, MEG, CCL and TARC are analyzed. All these parameter values fall within the standard requirement for MIMO antennas. The designed metamaterial MIMO antenna can be a good pick for 6G/TWPAN communication devices.
