A novel design of THz MEMS a-helix antenna using HFSS-based effective stochastic solvers

Abstract

The investigation of antennas based on Microelectromechanical Systems (MEMS) processing, has particularly reported major milestones to research in THz wave applications, due to the encouraging results afforded by the real progress of the different optimization techniques based on developed Computer Aided Design (CAD) tools, to provide a new class of antennas for THz systems covering relevant areas including communication, biomedicine, spectroscopy, and other emerging fields. This paper describes a novel design of MEMS A-Helix antenna developed using High Frequency Structure Simulator (HFSS) based on effective stochastic solvers. The antennas demonstrates a high performance resulting in very low Return Losses (RL) of less than −15dB to −35dB, and excellent Voltage Standing Wave Ratio (VSWR) of less than 1.4 to 1.04 for a wide range of frequencies from 2.29 THz to 2.63 THz. The optimized MEMS A-Helix antenna presents an excellent electromagnetic response using effective automatic techniques for optimizing various tunable parameters embedded in silicon platform including the helix variables and feeding line parameters.
