A New Conical Helix Antenna based on MEMS Technology using Genetic Algorithms

Abstract

The manufacturing of Micro-Electromechanical Systems (MEMS) antennas has recently outperformed major hurdles by reducing the long and expensive development cycles due to adequate Computer Aided Design (CAD) equipments with advanced optimization methods to address the special need for a new class of terahertz (THz) antennas, and model accurately the physical behavior of such three dimensional (3D) micro-devices. In this paper a new design of a highly miniaturized MEMS conical helix antenna modeled by High Frequency Structure Simulator (HFSS) based on Genetic Algorithms (GA), is proposed for THz wireless systems to present very low return losses of less than -20dB to -70dB and excellent voltage standing wave ratios of less than 1.20 to 1.00 for a wide frequency band ranging from 3.5 to 4.5 THz, resulting in excellent electromagnetic response and good directivity due to the high geometrical accuracy achieved using effective automatic techniques to rectify various tunable parameters embedded in silicon platform divided into helix variables and feeding line characteristics.
