Abstract :
The design of an antenna using metamaterials (MTM) for usage in the Terahertz frequency range is presented here. A detailed analysis of the ω-β curves, scattering (S) parameters and radiation patterns is done for a Composite Right/Left Handed (CRLH) transmission line metamaterials designed as a metal-metal (MM) waveguide that incorporates an hour glass slot unit cell structure. An array of the same in two dimension is studied next. This is followed by a study of the 3D stacked structure of the same MM-MTM. A final design configuration is proposed for application in active antenna systems.
