Gain enhancement of MEMS helix antenna using double substrate and fractal structures

This paper is concerned with the design of a novel MEMS helical antenna that is mainly incorporated for Terahertz (THz) applications. The antenna comprises of a metal helix and a CPW feed on the substrate. The antenna can be fabricated using only one wafer and it has high packaging density. For THz applications the antenna parameters has been optimised so that desired performance can be achieved. Moreover low fabrication cost makes this antenna suitable for terahertz systems.
